Not all information is created equal. The bottom layers (the most ubiquitous, whose sources are the most ephemeral, and with the least amount of validation) lead to layers with greater dependability, all the way to the highest layers, made up mostly of academic resources maintained and validated by academic publishers that use multiple peer reviews, trained editors, and scholarly reviewers. When the system is effective, the layers serve to reinforce one another through clear pathways that allow queries to move from one layer to another with little resistance.

Most of the nearly 2,500 students who responded said they consult Wikipedia, but when questioned more deeply, it became clear that they use it for, as one student put it, "pre-research." In other words, to gain context on a topic, to orient themselves, students start with Wikipedia. That makes perfect sense. Through user-generated efforts, Wikipedia is comprehensive, current, and far and away the most trustworthy Web resource of its kind. It is not the bottom layer of authority, nor the top, but in fact the highest layer without formal vetting. In this unique role, it therefore serves as an ideal bridge between the validated and unvalidated Web.

Of course, some people want a formal education. I do not think everyone should leave college, but I challenge my peers to consider the opportunity cost of going to class. If you want to be a doctor, going to medical school is a wise choice. I do not recommend keeping cadavers in your garage. On the other hand, what else could you do during your next 50-minute class? How many e-mails could you answer? How many lines of code could you write?

Say your “thank yous” and “good jobs” in hopes that this positivity will come back to you.

powerful learning depends on the quality of the conversation that develops around the content being studied together.

The study found that in 64 percent of children with ADHD, the symptoms were caused by food. "It's a hypersensitivity reaction to food," Pessler said.

But Pessler's study indicates that up to two-thirds -- or 2 of the 3 million children currently medicated for ADHD -- may not need medication at all. "With all children, we should start with diet research," Pessler said.

After three years on Ritalin, children were about an inch shorter and 4.4 pounds lighter than their peers, according to a major study published in the Journal of the American Academy of Child and Adolescent Psychiatry in 2007.

Test scores are an inadequate proxy for quality because too many factors outside of the teachers’ control can influence student performance from year to year — or even from classroom to classroom during the same year.

there’s a far more direct approach: measuring the amount of time a teacher spends delivering relevant instruction — in other words, how much teaching a teacher actually gets done in a school day.

Thirty years ago two studies measured the amount of time teachers spent presenting instruction that matched the prescribed curriculum, at a level students could understand based on previous instruction. The studies found that some teachers were able to deliver as much as 14 more weeks a year of relevant instruction than their less efficient peers.

Information and knowledge

These gains often turn out to be an achievement mirage

Three interconnected factors are as essential for whole-school achievement as knowing how to teach well: trust, collaboration, and authenticity.

professional learning is ongoing and embedded

uture is not out there to be "discovered": It has to be invented and designed.

Learning is a process of knowledge construction, not of knowledge recording or absorption. Learning is knowledge-dependent; people use their existing knowledge to construct new knowledge. Learning is highly tuned to the situation in which it takes place. Learning needs to account for distributed cognition requiring knowledge in the head to combined with knowledge in the world. Learning is affected as much by motivational issues as by cognitive issues.

previous notions of a divided lifetime-education followed by work-are no longer tenable.

What an indictment of the Ivy League and its peers: that colleges four levels down on the academic totem pole, enrolling students whose SAT scores are hundreds of points lower than theirs, deliver a better education, in the highest sense of the word.

Conscientiousness and Openness have the biggest influence on academic success.

people learn better when using multiple, short training episodes rather than one extended session

participants who held jobs with higher levels of complexity with data and people, such as management and teaching, had better scores on memory and thinking tests
