Social bookmarking. When you save a Web site as a favorite or bookmark, it's added to a list that stays within that browser. Use another computer, and you don't have access to that bookmark. When you use a social-bookmarking service, you save your bookmarks on that server, making them available to you wherever you access the Web, and allowing you to share them with others. Ask your students to create accounts on a social-bookmarking service and to bookmark Web sites, news articles, and other resources relevant to the course you're teaching. Create a unique "tag" for your course and have your students use it, so that their bookmarks can be easily found. Ask students to apply multiple tags to the resources they bookmark, as a way to help them locate their bookmarks quickly and to prepare them for the kind of keyword searching they'll need to do when using library databases. If you're teaching a face-to-face or hybrid class, be sure to spend some class time having students share their latest finds, so they can see the connections between this work outside class and classroom discussions. Students most likely won't find this difficult. After all, you're asking them to surf the Web and tag pages they like. That's something they do via Facebook every day. By having them share course-related content with their peers in the class, however, you'll tap into their desires to be part of your course's learning community. And you might be surprised by the resources they find and share.

Let’s start with what Khan Academy is. Khan Academy is a collection of video lectures that give demonstrations of mechanical processes. When it comes to this purpose, KA videos are, on the average, pretty good. Sal Khan is the main reason; he is approachable and has a knack for making mechanical processes seem understandable. Of course, his videos are not perfect. He tends to ramble a lot and get sidetracked; he doesn’t use visuals as effectively as he could; he’s often sloppy and sometimes downright wrong with his math; and he sometimes omits topics from his subjects that really need to be there (LU decomposition in linear algebra, for example). But on balance, KA is a great resource for the niche in which it was designed to work: giving demonstrations of mechanical processes.

But let’s also be honest about what Khan Academy is not. Khan Academy is not a substitute for an actual course of study in mathematics. It is not a substitute for a live teacher. And it is not a coherent curriculum of study that engages students at all the cognitive levels at which they need to be engaged. It’s OK that it’s not these things. We don’t walk into a Mexican restaurant and fault it for not serving spaghetti. I don’t fault Khan Academy for not being a complete educational resource, because it wasn’t designed for that purpose. Again, Khan Academy is a great resource for the niche in which it was designed to work. But when you try to extend it out of that niche — as Bill Gates and others would very much like to do — all kinds of things go wrong.

When we say that someone has “learned” a subject, we typically mean that they have shown evidence of mastery not only of basic cognitive processes like factual recall and working mechanical exercises but also higher-level tasks like applying concepts to new problems and judging between two equivalent concepts. A student learning calculus, for instance, needs to demonstrate that s/he can do things like take derivatives of polynomials and use the Chain Rule. But if this is all they can demonstrate, then it’s stretching it to say that the student has “learned calculus”, because calculus is a lot more than just executing mechanical processes correctly and quickly. To say that it is not — that knowledge of calculus consists in the ability to perform algorithmic processes quickly and accurately — is to adopt an impoverished definition of the subject that renders a great intellectual pursuit into a collection of party tricks.

Control, whether by threats or bribes, amounts to doing things to children rather than working with them. This ultimately frays relationships

The alternative to bribes and threats is to work toward creating a caring community whose members solve problems collaboratively and decide together how they want their classroom to be

grades in particular have been found to have a detrimental effect on creative thinking, long-term retention, interest in learning, and preference for challenging tasks

I’m concerned that most one-to-one implementation strategies are based on the new tool as the focus of the program. Unless we break out of this limited vision that one-to-one computing is about the device, we are doomed to waste our resources.

Then, teachers are instructed to go! But go where?

I believe every student must have 24-7 access to the internet.

The new standards instead propose that teachers move students purposefully through increasingly complex text to build skill and stamina.

higher-order thinking in reading depends heavily on knowledge of word meanings.

Students' ability to comprehend a piece of text depends on the number of unfamiliar domain-specific words and new general academic terms they encounter.
