As we begin implementing the Common Core State Standards this year, many of the schools I advise are having very similar problems with grade-level readiness. This isn’t a new problem, to be sure, but it has become intensified by Common Core expectations. The Common Core standards are more rigorous than last year’s New York State standards, so even students who were on grade level last year have some catching up to do. Also, built into the DNA of the Common Core is the idea of a “staircase of complexity” in which students must master the standards of the prior year before they are ready for the standards of the current year. In other words, they must master the 5th-grade standards in order to become 6th-grade ready.

For example, students in Kindergarten learn to state an opinion (”My favorite book is…”). In Grade 1, they provide a reason for their opinion. In Grade 4, they support their reasons with information, while in Grade 6 they write arguments to support claims with reasons and evidence. In math, students are expected to be effortlessly fluent in addition and subtraction by the end of Grade 2, so they will be ready to begin fractions in Grade 3. By the end of Grade 5, their understanding of fractions is thorough enough to begin algebra in the 6th grade. It’s a well-structured progression that brings students step-by-step from Kindergarten to college and career readiness by providing incremental support based on the learning that has accrued through the previous years of instruction in every grade.

What happens, then, during the first year of implementation? Our students aren’t even coming in on grade level based on the old standards, let alone the more rigorous standards demanded by (and required for) the Common Core. Our 6th graders aren’t coming in having mastered fractions or the opinion essay. Their reading levels do not prepare them to approach the complex texts in the new reading band levels, which themselves are set higher than previous levels by the Common Core (as can be seen in the chart at the bottom of page 8 of the ELA Appendix A):

(Click for a larger image.)

And this problem is even more profound in high school, where the high-stakes Regents Exams are looming, and many students aren’t even prepared to read the instructions.

In a December 2011 keynote titled “What Must Be Done in the Next Two Years” (you can download the transcript here), David Coleman, the architect of the Common Core Standards, addresses the idea of grade-level readiness. He’s a brilliant man who speaks with a persuasive confidence, but he’s on the wrong side of this particular issue.

But for your sakes, the really exciting thing is for the first time there’s a measure in the standards that insists that students at each level are encountering texts of adequate complexity.

Nonetheless, you could nonetheless be defeated, because the most popular instructional practice for students who are behind is to replace their core reading with leveled text at their level, right? So if you were to actually look at what your kids are being given, they are constantly matched in this seeming noble idea that you should match everything they read to where they are today, often called a proximal zone of development, et cetera.

Let me be rather clear. Leveled readers and reading at your own level has a crucial role to play for kids in terms of their vocabulary growth, their love of reading, and has a very important role, so I’m not saying kind of just get rid of it. But what I am saying is the core of instruction, if we want kids to catch up, has to be the deliberate study of sufficiently complex texts, again and – we cannot exclude students from that and expect them to magically catch up. That’s a scaffolded environment, do you get me? Where their frustration – they are expected to be frustrated. That frustration is managed. It’s part of the classroom community, and they engage repeatedly in dealing with things that are more difficult than they can handle.

First of all, it’s the Zone of Proximal Development (ZPD), not the “proximal zone of development, et cetera.” I’m less bothered by his mixing the words around than I am by the “et cetera,” as if to say “yeah, there was more but I couldn’t be bothered to absorb it.” The ZPD is the range between what a child can do independently and what that same child can do with support. The concept was first described by Soviet psychologist Lev Vygotsky in the 1930’s, and has had a profound impact on developmental psychology and learning science. You can’t be dismissive of the ZPD in one breath, and then go on to recommend scaffolding in the next. The very idea of scaffolding is based on a Vygostkian model of development. The term was introduced by American psychologist Jerome Bruner, and it refers to the supports that we provide students within their ZPD to help them achieve at higher levels. As the metaphor suggests, once students can do these tasks independently, we can remove the scaffolding.

Coleman’s right that there should be managed frustration. If students read texts that are too easy for them, they may enjoy those texts, but it’s not the best way to support reading progress. When students have to read within their ZPD, they feel a frustration we might accurately describe as growing pains. They experience a stretch, and in that stretch, learning can actually help drive cognitive development. If, on the other hand, the material is above the upper limit of their ZPD, they will not experience that productive frustration. They will simply shut down and not attempt to read the material at all. And there is no amount of scaffolding that will make it possible. Think of a weight you can lift easily, a weight that requires some effort to lift, and a weight you can’t budge at all. Which of those three weights would you choose if you wanted to promote muscle growth?

So if you have students who are one or two grades below grade level, it might be worth trying to push them in the way Coleman describes. But students who are four, five, six years below their grade level, aren’t going to be reading on grade level by the end of the year no matter whose philosophical outlook you subscribe to. Nobody is expecting them to “magically catch up.” The idea is to support them in making the greatest progress possible. It is Coleman who is invoking magic when he expects that these students will be able to catch up simply through teacher patience, student frustration, and intense scaffolding.

But if anybody should be a proponent of Vygotsky, it’s David Coleman himself, for Vygotsky provides a clear developmental framework for the Common Core. If learning really can drive development, and I believe it can, then having a rigorous set of standards defined for each grade level organized into a staircase of complexity makes a lot of sense. If we adhere to these standards from Kindergarten, making sure that students receive support in a multi-tiered Response to Intervention system to ensure that they remain on grade level at the end of each year, then the Common Core might actually be a blueprint for making sure that our students are well prepared for the rigors of college and the workplace by the end of Grade 12. Wouldn’t it be a shame if that were all true and the Common Core really is a better way of doing business, but nobody ever knew it because the implementation was so badly botched?

So what can we do? If I were in charge of implementation, I would have had two years of bridge standards before fully adopting the Common Core. If the 5th grade NYS standards say ABC and the 8th grade Common Core standards say JKL, then we develop a logical DEF for 6th grade and a 7th-grade GHI that allow us to incrementally meet the higher standards. Instead, we’re going right from 5th-grade NYS to 6th-grade Common Core, and even students that were on grade level last year are being left behind. The folks at the New York City Department of Education, for their part, seem to understand the difficulties involved, and are trying to make the changes as gradually as possible to support teachers. But no such support is available for students, as the level of rigor expected for them is coming from Albany, and is out of the city’s hands.

I can’t tell you what the statewide assessments are going to look like at the end of this year, but I’m pretty sure the students are going to be expected to read on what is now considered grade level, and this is the problem. What do you do if you have 8th-grade students reading on a 4th-grade level, when you know you are going to be accountable for them passing an 8th-grade test at the end of the year? One option is, as Coleman describes, to give them 8th-grade reading selections anyway, have them read fewer overall texts, and heavily scaffold the texts being read. Another option is to try to give them two years of instruction in a year, committing to bring them from a 4th-grade level to 6th-grade level. Neither strategy will prepare them to read on the 8th-grade level by test time, but I prefer the latter method. It’s better to make meaningful progress in the time that you have than to squander the opportunity by fumbling around with inappropriately difficult texts. I understand, respect, and even admire Coleman’s desire to get everyone on grade level. It’s not going to happen this year.

Given that some of the quantitative targets may not be possible this year, another option is to focus on the qualitative shifts. Give students more exposure to informational texts. Give them more complex texts than they are reading now. Have them read more independently, and give them opportunities to cite evidence from the things they read to support their writing. These are all Common Core-aligned shifts, and can be implemented right away, regardless of student reading levels.

Finally, teachers can make a big difference by differentiating instruction. Some students may have higher upper bounds in their ZPD than might be apparent at first. And if you’ve agreed with me up until now, follow me the rest of the way. It’s important for teachers to challenge their students to the highest extent as is possible for them. Students will push back, but being a teacher means to encourage students to do more than they ever thought they could. Now is the time to do that. Please don’t mistake my nuanced understanding of cognitive development for timidity. I’ve taught Shakespeare, in the original language, to low-performing 5th graders. But to do that, I had to have some confidence that my learning goals were within their Zone of Proximal Development. And when they were, it turns out that it was possible!

As for the end-of-the-year tests, the whole state is in the same bind, so relative success is still very much in reach given the right strategies. Students feel growing pains, and so do teachers. But that pain just means that we’re working outside of our comfort zone, and are instead in a zone that is more conducive to growth.

New research from Liverpool University shows that Shakespeare (and other classical writers) can stimulate the brain. For me, what stood out from earlier studies, was the attention to the duration of the phenomenon:

The study went on to test how long the effect lasted. It found that the “peak” triggered by the unfamiliar word was sustained onto the following phrases, suggesting the striking word had hooked the reader, with their mind “primed for more attention”.

This means that if you’re experiencing a work by Shakespeare, who is constantly throwing these poetic curve balls, you can sustain the brain boost over long periods of time. I’ve certainly experienced this sensation many times. I’ll basically go to see any Shakespeare play, regardless of the venue, just so I can hear these words spoken to me. I participate in a monthly Shakespeare reading group, and feel the effect even more profoundly when I am the one reading the words.

Even seeing the text written can do the job, though I often pause a lot when reading and so the pace isn’t necessarily the same. But the research shows an increase in reflection as well, so perhaps that’s a different manifestation of the effect. I subscribe to a Twitter feed that only tweets the plays themselves, one line every ten minutes like clockwork. Every now and then I’ll hit a familiar line and feel the brain bolt. I don’t know why that should be, but I get my shot to the brain all the same.

If I’m doing something that requires no mental attention, I’ll listen to an audio lecture. If I’m doing something that requires my full attention, I’ll listen to music. But if I’m doing something tedious that needs some focus but provides no mental stimulation, I’ll listen to Shakespeare. I’ll typically choose an audio production that I’ve listened to many times before, so I don’t need to be an engaged audience member the whole time. But I find that I can keep my conscious mind engaged on the task much more easily if my subconscious mind is swept away on a wave of poetic bliss. And when a line or two does drift into my awareness, I know the play well enough that I can enjoy it out of context, much like I do the Twitter feed. I get the hit without having to break my stride.

This is your brain on Shakespeare. Any questions?

Today, I worked with science teachers on their performance tasks. Actually, I’ve been doing a lot of consulting this year on performance tasks, which is the hot new trend in assessment.

A performance task is an opportunity for students to demonstrate that they can independently apply the skills they’ve learned in a real-world context. So it’s like a post-test, only instead of multiple-choice questions, students have to do an authentic activity. Teachers examine the resulting student work with a rubric to measure whether or not students have learned the skills, and they can then use this information to plan future instruction. It’s much more effective than standardized-testing data in diagnosing student needs, though I do admit it is much more time-consuming.

This year, I’ve been working a lot with social studies and science teachers. Because of the Common Core shifts, these teachers are now required to teach literacy skills. There are no actual content standards in social studies or science in the Common Core; all of the standards for these subject areas are literacy standards. There are science content standards currently under development by Next Generation. When they are completed, states will have the option of adopting them in the same way they adopted Common Core. But until then, science content standards come from the states, and literacy standards from the Common Core are applied across the curriculum.

Now, I actually like the idea of literacy across the curriculum, but it is a big adjustment for science and social studies teachers, and so the schools where I consult have asked me to work with these teachers to help them infuse literacy skills into their curriculum and their assessments, particularly the performance tasks that New York City is requiring them to administer this year.

I have had a lot of experience working with social studies teachers in the past, but I’m probably working more with science teachers this year than I ever have before. And that’s fantastic, because I get the opportunity to learn a lot of new things. I also get the chance to yell “Science!” like Magnus Pyke a lot. No, I don’t really do that, but it would be fun.

One of the science teachers I worked with today swears by a website for an organization called Urban Advantage. It has some great resources for teaching middle-school science with an inquiry-based approach. I like the way that their materials scaffold scientific writing, which is my focus this year.

Another science teacher I worked with today showed me the PhET website, which has some really compelling interactive simulations in the sciences. I watched 7th-grade students run a simulation on density, in which they had to determine the mass and volume of various mystery substances and identify them from a list of materials and their densities.

Science!

From Hamlet:

I cannot live to hear the news from England;
But I do prophesy the election lights
On Fortinbras.

Shift around the letters, and it becomes:

Math prognosticator Nate Silver predicted the whole state finishing roll, one-none.

Fun hobby!

Okay, so I missed the riddle this week. I do apologize, but I’ve been constantly besieged by natural disasters of biblical proportions. Sort of.

I was actually in Virginia for the earthquake. I’ve spent the last week vacationing with my family, visiting Jamestown and Williamsburg and the like. On Tuesday, we were at Busch Gardens, and when the group split into different factions, I took the opportunity to set off on my own for a while. I went to go see the Pirates “4-D” movie. A “4-D” movie is like a 3-D movie, except they shake your seat and squirt water at you at appropriate moments in the film. It has nothing to do with the fourth dimension, but it’s fun all the same. At one point, the whole theatre shook from side to side, which I thought was pretty cool, but I later learned that I was actually at the epicenter of a 5.8-magnitude earthquake. It even kind of fit with what was going on in the movie, so I just enjoyed it as part of the show.

After I left the theatre, I ran into my nephew Ian (age 7), accompanied by Dave, a family friend. Dave told me that there had been some kind of earthquake, and that all of the rides were shut down. I assumed that this was a story Dave told Ian to get a break from the roller coasters, so I gave him a knowing smile and went along with the charade. It’s worth noting that, at this point, I had both felt the earthquake and had been told there was an earthquake, and still I did not know there had been an earthquake.

Pretty soon, however, it became hard for even me to stay in the dark, as reports of the unusual phenomenon spread rapidly. It stayed big news for a day or two, but was just as quickly overshadowed by news of an impending hurricane. Hurricane Irene was expected to sweep up the Eastern seaboard and hit New York City by Saturday night. I decided to cut my trip short a day and head back home a bit early. My train was delayed a bit because of flooding below Washington, D.C., but my trip was largely uneventful and I made it back to New York City in time to do some grocery shopping and put my earthly affairs in order.

As I settled in for a grocery-enhanced night of a Kill Point marathon sporadically interrupted by checking online weather maps, I learned of an impending Tornado Watch for New York City. Really?

Anyway, there was no tornado, and not even really a hurricane. Irene was downgraded to a tropical storm before it hit here, and even by that standard, it was pretty mild. I had no interruptions of power or Internet, and could only occasionally hear the rustling of wind outside my window. I did make it through the entire series of The Kill Point, which was about a hostage standoff in a bank, so that was pretty exciting, but that was about it. I can’t say I’m disappointed, but I’m not feeling all that relieved either.

Mostly, I’m disappointed that I missed a riddle, which usually means I’ve been neglecting the blog for too long. I think I’m about ready to return. This week, I survived earthquakes, hurricanes, floods, and tornadoes, so I’m feeling pretty unstoppable. That’s right, Mother Nature, if you want a piece of this, next time you best bring a FREAKIN’ VOLCANO.

Feel free to post relevant quotes from King Lear in the comments. The Shakespeare Teacher is back.

Last week, an IBM computer named Watson beat Ken Jennings and Brad Rutter, the two greatest Jeopardy! players of all time, in a nationally televised event. The Man vs. Machine construct is a powerful one (I’ve even used it myself), as these contests have always captured progressive imaginations. Are humans powerful enough to build a rock so heavy, not even we can lift it?

Watson was named for Thomas J. Watson, IBM’s first president. But he could just as easily have been named after John B. Watson, the American psychologist who is considered to be the father of behaviorism. Behaviorism is a view of psychology that disregards the inner workings of the mind and focuses only on stimuli and responses. This input leads to that output. Watson was heavily influenced by the salivating dog experiments of Ivan Pavlov, and was himself influential in the operant conditioning experiments of B.F. Skinner. Though there are few strict behaviorists today, the movement was quite dominant in the early 20th century.

The behaviorists would have loved the idea of a computer playing Jeopardy! as well as a human. They would have considered it a validation of their theory that the mind could be viewed as merely generating a series of predictable outputs when given a specific set of inputs. Playing Jeopardy! is qualitatively different from playing chess. The rules of chess are discrete and unambiguous, and the possibilities are ultimately finite. As Noam Chomsky argues, language possibilities are infinite. Chess may one day be solved, but Jeopardy! never will be. So Watson’s victory here is a significant milestone.

Much has been made of whether or not the contest was “fair.” Well, of course it wasn’t fair. How could that word possibly have any meaning in this context. There are things computers naturally do much better than humans, and vice versa. The question instead should have been in which direction would the unfairness be decisive. Some complained that the computer’s superior buzzer speed gave it the advantage, but buzzer speed is the whole point.

Watson has to do three things before buzzing in: 1) understand what question the clue is asking, 2) retrieve that information from its database, and 3) develop a sufficient confidence level for its top answer. In order to achieve a win, IBM had to build a machine that could do those things fast enough to beat the humans to the buzzer. Quick reflexes are an important part of the game to be sure, but if that were the whole story, computers would have dominated quiz shows decades ago.

To my way of thinking, it’s actually the comprehensive database of information that gives Watson the real edge. We may think of Ken and Brad as walking encyclopedias, but that status was hard earned. Think of the hours upon hours they must have spent studying classical composers, vice-presidential nicknames, and foods that start with the letter Q. Even a prepared human might temporarily forget the Best Picture Oscar winner for 1959 when the moment comes, but Watson never will. (It was Ben-Hur.)

In fact, given what I could see, Watson’s biggest challenge seemed to be understanding what the clue was asking. To avoid the complications introduced by Searle’s Chinese Room thought experiement, we’ll adopt a behaviorist, pragmatic definition of “understanding” and take it to mean that Watson is able to give the correct response to a clue, or at least a reasonable guess. (After all, you can understand a question and still get it wrong.) Watching the show on television, we are able to see Watson’s top three responses, and his confidence level for each. This gives us remarkable insight into the machine’s process, allowing us a deeper level of analysis.

A lot of my own work lately has been in training school-based data inquiry teams how to examine testing data to learn where students need extra help, and that work involves examining individual testing items. So naturally, when I see three responses to a prompt, I want to figure out what they mean. In this case, Watson was generating the choices rather than simply choosing among them, but that actually makes them more helpful in sifting through his method.

One problem I see a lot in schools is that students are often unable to correctly identify what kind of answer the question is asking for. In as much as Watson has what we would call a student learning problem, this is it. When a human is asked to come up with three responses to a clue, all of the responses would presumably be of the correct answer type. See if you can come up with three possible responses to this clue:

Category: Hedgehog-Pogde
Clue: Hedgehogs are covered with quills or spines, which are hollow hairs made stiff by this protein

Watson correctly answered Keratin with a confidence rating of 99%, but his other two answers were Porcupine (36%) and Fur (8%). I would have expected all three candidate answers to be proteins, especially since the words “this protein” ended the clue. In many cases, the three potential responses seemed to reflect three possible questions being asked rather than three possible answers to a correct question, for example:

Category: One Buck or Less
Clue: In 2002, Eminem signed this rapper to a 7-figure deal, obviously worth a lot more than his name implies

Ken was first to the buzzer on this one and Alex confirmed the correct response, both men pronouncing 50 Cent as “Fiddy Cent” to the delight of humans everywhere. Watson’s top three responses were 50 Cent (39%), Marshall Mathers (20%), and Dr. Dre (14%). This time, the words “this rapper” prompted Watson to consider three rappers, but not three potential rappers that could have been signed by Eminem in 2002. It was Dr. Dre who signed Eminem, and Marshall Mathers is Eminem’s real name. So again, Watson wasn’t considering three possible answers to a question; he was considering three possible questions. And alas, we will never know if Watson would have said “Fiddy.”

It seemed as though the more confident Watson was in his first guess, the more likely the second and third guesses would be way off base:

Category: Familiar Sayings
Clue: It’s a poor workman who blames these

Watson’s first answer Tools (84%) was correct, but his other answer candidates were Yogi Berra (10%) and Explorer (3%). However Watson is processing these clues, it isn’t the way humans do it. The confidence levels seemed to be a pretty good predictor of whether or not a response was correct, which is why we can forgive Watson his occassional lapses into the bizarre. Yeah, he put down Toronto when the category was US Cities, but it was a Final Jeopardy, where answers are forced, and his multiple question marks were an indicator that his confidence was low. Similarly cornered in a Daily Double, he prefaced his answer with “I’ll take a guess.” That time, he got it right. I’m just looking into how the program works, not making excuses for Watson. After all, it’s a poor workman who blames Yogi Berra.

But the fact that Watson interpreted so many clues accurately was impressive, especially since Jeopardy! clues sometimes contain so much wordplay that even the sharpest of humans need an extra moment to unpack what’s being asked, and understanding language is our thing. Watson can’t hear the the other players, which means he can’t eliminate their incorrect responses when he buzzes in second. It also means that he doesn’t learn the correct answer unless he gives it, which makes it difficult for him to catch on to category themes. He managed it pretty well, though. After stumbling blindly through the category “Also on Your Computer Keys,” Watson finally caught on for the last clue:

Category: Also on Your Computer Keys
Clue: Proverbially, it’s “where the heart is”

Watson’s answers were Home is where the heart is (20%), Delete Key (11%), and Elvis Presley quickly changed to Encryption (8%). The fact that Watson was considering “Delete Key” as an option means that he was starting to understand that all of the correct responses in the category were also names of keys on the keyboard.

Watson also is not emotionally affected by game play. After giving the embarrassingly wrong answer “Dorothy Parker” when the Daily Double clue was clearly asking for the title of a book, Watson just jumped right back in like nothing had happened. A human would likely have been thrown by that. And while Alex and the audience may have laughed at Watson’s precise wagers, that was a cultural expectation on their part. There’s no reason a wager needs to be rounded off to the nearest hundred, other than the limitations of human mental calculation under pressure. This wasn’t a Turing test. Watson was trying to beat the humans, not emulate them. And he did.

So where does that leave us? Computers that can understand natural language requests and retrieve information accurately could make for a very interesting decade to come. As speech recognition improves, we might start to see computers who can hold up their end of a conversation. Watson wasn’t hooked up to the Internet, but developing technologies could be. The day may come when I have a bluetooth headset hooked up to my smart phone and I can just ask it questions like the computer on Star Trek. As programs get smarter about interpreting language, it may be easier to make connections across ideas, creating a new kind of Web. One day, we may even say “Thank you, Autocorrect.”

It’s important to keep in mind, though, that these will be human achievements. Humans are amazing. Humans can organize into complex societies. Humans can form research teams and develop awesome technologies. Humans can program computers to understand natural language clues and access a comprehensive database of knowledge. Who won here? Humanity did.

Ken Jennings can do things beyond any computer’s ability. He can tie his shoes, ride a bicycle, develop a witty blog post comparing Proust translations, appreciate a sunset, write a trivia book, raise two children, and so on. At the end of the tournament, he walked behind Watson and waved his arms around to make it look like they were Watson’s arms. That still takes a human.

UPDATE: I’m told (by no less of an authority than Millionaire winner Ed Toutant) that Watson was given the correct answer at the end of every clue, after it was out of play. I had been going crazy wondering where “Delete Key” came from, and now it makes a lot more sense. Thanks, Ed!

Here’s a video that can be enjoyed both by younger viewers and older viewers, but in very different ways.

This clip of The Today Show is apparently from January 1994. The hosts ponder over a new entity that seems to be cropping up all over the place, the strange and magical new Internet. If it’s not obvious, the person on the left is Katie Couric, the current anchor of The CBS Evening News.

The point of this is not to make fun of the hosts who, 17 years ago, could hardly have been expected to understand how ubiquitous the Internet would become in our lives. But the clip is intriguing as a frozen moment in time, recalling the days when you had to check the newspaper for movie listings and you had to buy stamps to mail a letter. Back then, the thought of someone like me writing something like this and having someone like you come here and read it would have been unthinkable.

Now if you’ll excuse me, I’m going outside to do a video chat on my mobile phone.

There’s a really good article on “The Economics of Global Warming” in Newsweek:

The most likely consequences of climate change will be severe impacts on food production in the developing world. We can worry about urban heat waves, polar bears, and forest fires, but the worst effects are almost certainly going to be on food production in the poor countries, where half or more of the population depends on growing its own food.

Estimates of lost world product due to climate change are moderate because the poor have so little to lose. More than a billion people, maybe 2 billion, are estimated to live on less than the equivalent of $2 per day. If a billion of those poorest people lost half their income, it would be an overwhelming tragedy, a true catastrophe, worse than all the earthquakes, floods, tsunamis, landslides, and fires of the past decade happening every year. But those billion people together would lose only $365 billion per year. That is less than 1 percent of world income! They have so little to begin with that what they can lose doesn’t amount to much of a statistic. But they can lose tragically.

It’s not a long article, so click here to read the whole thing.

I thought it might be fun to try something new with the “Question of the Week” feature here on the blog. Instead of asking my readers a question, I will offer up a question from the statewide examinations that New York City students take each year.

The purpose of this will not be for you to try to provide the correct answer, but rather to join me in examining the question. What does it tell us about student understanding? What do each of the wrong answers mean? What is this question testing? What is it really testing? What would students need to know and be able to do to answer this question correctly?

Sound like fun?

To differentiate this feature from the Question of the Week, I’ll call this the Item of the Week, which is what we call questions in the parlance of standardized testing.

Today’s item comes from the 2010 New York State Grade 4 Mathematics Exam. The strand is Measurement and the performance indicator is “4.M04 Select tools and units appropriate to the mass of the object being measured (grams and kilograms).” You can click the image for a larger view.

I like the layering of this question. First of all, the student needs to know which units measure mass and which don’t. If they answer A or D, they don’t. But to choose between B and C, students need to have some idea of how much a gram really is.

Sometimes these questions will have distractor answers that use numbers from the problem to try to trick students into choosing them. But there are no numbers in this problem. And all of the answers use the same number.

The trick here is in the first sentence. The fact that Mr. Patel moved his chair across the room is not relevant. But if you don’t know what “mass” means, that first sentence might trick you into thinking you are looking for a distance, in which case you might choose D. This assumes, of course, that you have no idea how long a kilometer is.

All in all, it seems like a pretty fair question that tests what it purports to test. In practice, it turned out to be one of the harder items for New York City students taking this exam.

As always, I invite further discussion.

Last year, I wrote that I didn’t need an iPad, because I had an iPhone and a Macbook Air. I still have them both, and they are still working out great. But my nephews got iPads for the holidays, and this is how I bond with them, so I had to get an iPad too. How’s that for a rationalization?

But now that I’ve bought one, I’m glad I did, because it’s adding value in ways I hadn’t anticipated. True, it is basically an iPod Touch with a larger screen, but that larger screen makes a big difference. There are a lot of things I can technically do with my iPhone, but usually don’t because the screen size is too small. And I’m finding it easier to do those things on the iPad.

So here are the top ten things you can do on an iPhone or iPod Touch that you can do better on an iPad:

1. Watch: I’ve been carrying around movies and TV shows on my iPhone for years, but I’ve watched more on the iPad in the last couple of months than I ever watched on the little screen. The Videos app (Included) is the very first app on my iPad. But I’ve also signed up for accounts with Netflix (Free app + $7.99/mo.) and Hulu Plus (Free app + $7.99/mo.) that let me stream video content from their impressive libraries. The combined monthly cost is far, far less than the Cable TV I’m canceling. And apps for YouTube (Included) and ABC Player (Free) help establish the iPad as a truly flexible video viewer you can take anywhere.

2. Connect: The power of social media has risen incredibly in the past year, and the App Store (Included) has kept pace. There are a variety of apps to help keep you connected, but I use Reeder ($4.99) as my Google Reader client, Friendly (Free) as my Facebook client, and Twitter (Free) as my client to access the Twitter account I finally broke down and created so that I could follow the national conversation where it seems to have gone. You can also consolidate the three, and much more, in one app called Flipboard (Free), which formats the content into a friendly magazine layout for casual browsing. There is also a WordPress app (Free), which allows me to blog on the go, and Yahoo! Messenger (Free) – actually an iPhone app – which lets users exchange text messages and participate in voice chat. And the iPad Mail interface (Included), designed for the larger screen, is much easier to use than its iPhone counterpart.

3. Read: The biggest surprise for me on the iPad is how much I love my Kindle app (Free), which lets me download books from Amazon and read them on the iPad. And these are real books that I actually want to read, not the limited eBook selection available through Apple. However, there are a lot of places online to get free books in ePub format, which can then be imported into your iTunes library and read on iBooks (Free), so you should definitely get it. I’m a fan of Offline Pages ($4.99), which allows you to save websites (from the iPad or from your home computer) and read them on the iPad, even after you’re no longer connected to the Internet. I also highly recommend the Shakespeare Pro app ($9.99) if Shakespeare’s your thing, and the Newspapers app ($2.99), which lets you access local newspapers from across the country on a daily basis.

4. Play: Any game you can play on the iPhone, you can play on the iPad, either in the original size, or expanded to fit the screen (sometimes with the expected loss of quality). But the expanded real estate has given developers something to code about, so there is a whole spate of new games and revamped versions of old games at the ready. Plants vs. Zombies is the absolute best game to ever grace the iPhone, and Plants vs. Zombies HD ($6.99) is even better on the iPad. Games like Cover Orange HD ($0.99) and Cut the Rope HD ($1.99), which combine tricky puzzles with engaging animations, demonstrate a new level of what is possible in portable gaming. Even the simple games, like Saving Seeds HD ($0.99) or Aces Traffic Pack HD ($2.99), really make you feel like you’re using a next generation device. I was able to play GT Racing: Motor Academy ($0.99) with my two nephews, each of us on our own iPads, racing each other on the same track. This was cool on a level they could not possibly appreciate.

5. View: I’d be remiss if I didn’t discuss how viewing photos is better on the larger screen, obvious as it may be. The iPad has a built-in Picture Frame feature, which lets the device function as a digital picture frame when it’s not otherwise in use. There are also apps that take advantage of the view, like Beautiful Planet HD ($0.99) that shows high-quality images from across the globe, and The Guardian Eyewitness (Free), which shows a different news photo every day. And The Elements ($13.99), the flagship app of the iPad, is everything it’s hyped to be: an interactive periodic table in which you can rotate high-quality 3D images of each of the elements. But it does take up almost 2GB of storage space, so don’t even bother with it if you’re only working with 16GB.

6. Work: The iPad is expensive to begin with, so it seems worth it to me to invest just a bit more in the iWork suite – Pages ($9.99), Numbers ($9.99), and Keynote ($9.99) – to add value to your device. I’ve also become fond of GoodReader ($2.99), which reads PDF files, and Teleprompt+ ($9.99), which allows you to load up text documents from your desktop and use the iPad as your own portable teleprompter. Try that with an iPhone.

7. Organize: I’ve actually not had a problem with the Calendar app on the iPhone, but the iPad’s Calendar interface (Included) makes it possible to see my whole month at a glance, which is a useful feature. As a MobileMe user, I like to use iDisk (Free app + $99/yr. for MobileMe) to coordinate between my desktop, laptop, iPhone, and iPad, but if you’re not a member, I’ve heard good things about Dropbox (Free app + Dropbox account). And I have to mention the Delivery Status app ($4.99), which lets you follow multiple packages from FedEx, UPS, etc. as they are tracked through the system.

8. Browse: The fact that the iPhone had a fully functioning web browser was a major breakthrough, but the iPad takes it a step further. It’s not only that the screen is larger, but also the fact that it allows you to view the full versions of your favorite websites, as opposed to the version optimized for mobile devices. Safari (Included) also syncs your bookmarks bar from its desktop counterpart (via MobileMe, I think), which I have found very convenient. It’s worth checking to see if the websites you frequent have their own apps as well. I recommend Google (Free), WolframAlpha ($1.99), and Articles ($4.99), which is a sharp-looking Wikipedia client.

9. Explore: Here’s how you know you are living in the future. Download GoSkyWatch Planetarium (Free) to your iPad. Then point it at the sky at night. It will display for you the same stars at which you are gazing, along with their names and even the constellations drawn in. Move the iPad around and the display will adjust. It’s also worth getting Solar Walk ($2.99), which gives you more freedom to move around the solar system and see what’s going on, including watching our own artificial satellites as they orbit around the Earth. The more expansive interface also breathes new life into old favorites such as Maps (Included) and Google Earth (Free).

10. Distract: So you’ve bought your iPad and now the kids want to play with it. What can you download to keep them out of your online banking app? The boys have their favorites, but Elena, who is now almost two, can work the icons along with the best of them, even knowing to hit the menu button when she’s bored with one app and wants to switch to another. Voting with her fingers, she recommends Sound Touch ($2.99), Art in Motion ($2.99), Tesla Toy ($1.99), and Drawing Pad ($0.99). Ian (age six) is really into roller coasters, so he enjoys games like New York 3D Rollercoaster Rush HD ($4.99) and Underground 3D Rollercoaster Rush HD ($4.99). But he really loves an app called Coaster Physics ($0.99), which lets him design his own roller coaster and then ride on it as he learns about kinetic and potential energy. He also likes to practice his Dolch sight words with All Sight Words ($0.99) and play Math Bingo ($0.99), while his older brother Jason (age eight) prefers MathBoard ($3.99) to hone his arithmetic skills. I highly recommend the BrainPOP Featured Movie (Free) and PBS’s SUPER WHY! ($3.99), two excellent educational apps by sources from whom we’d expect no less. And there are a whole host of apps that simulate baking different sugary confections, but Cupcakes! XL ($0.99) makes the best use of the iPad’s capabilities.

I certainly mean no disrespect to the iPhone. It’s still, hands down, the coolest thing I’ve ever owned, including the iPad. It has a phone and a camera and it fits in my pocket, so the new kid is really no threat. The iPhone is also better for listening to audio, recording voice memos, MusicID, and playing Doodle Jump or Catan. Most of the things I do with the iPad are things I wasn’t really doing with the iPhone anyway. So the iPad did add value after all.

And now all of my portable digital requirements really are met, and I therefore have no need for any new thing that should happen to be introduced by Apple or anyone else.

Do I?
