The studying that middle school and high school students do after the dismissal bell rings is either an unreasonable burden or a crucial activity that needs beefing up. Which is it? Do American students have too much homework or too little? Neither, I’d say. We ought to be asking a different question altogether. What should matter to parents and educators is this: How effectively do children’s after-school assignments advance learning?

The quantity of students’ homework is a lot less important than its quality. And evidence suggests that as of now, homework isn’t making the grade. Although surveys show that the amount of time our children spend on homework has risen over the last three decades, American students are mired in the middle of international academic rankings: 17th in reading, 23rd in science and 31st in math, according to results from the Program for International Student Assessment released last December.

“Spaced repetition” is one example of the kind of evidence-based techniques that researchers have found have a positive impact on learning. Here’s how it works: instead of concentrating the study of information in single blocks, as many homework assignments currently do — reading about, say, the Civil War one evening and Reconstruction the next — learners encounter the same material in briefer sessions spread over a longer period of time. With this approach, students are re-exposed to information about the Civil War and Reconstruction throughout the semester.

On Wednesday, Mr. Gardner will celebrate his 95th birthday with the publication of another book — his second book of essays and mathematical puzzles to be published just this year. With more than 70 books to his name, he is the world’s best-known recreational mathematician, and has probably introduced more people to the joys of math than anyone in history.

After four years at the charter school, eighth-graders showed average test score gains in math equal to an additional year and a half of school, compared with district students.

the charter has a lean administrative staff and slightly larger classes—31 students compared with an average of about 26 or 27 in district schools—so it can pour resources into teacher pay and training.

Benoit Mandelbrot, who died on October 14 aged 85, was largely responsible for developing the discipline of fractal geometry – the study of rough or fragmented geometric shapes or processes that have similar properties at all levels of magnification or across all times.
