Focus on depth in high school leads to greater success in college

Physorg.com - Study finds that students benefit from depth, rather than breadth, in high school science courses

A large study done on over 8,000 college students found that those that spent a month or more on a single topic in high school science classes got higher science grades in general than students who covered more topics over the same time period. Cryptically, the reports claim that students who focused on fewer topics in greater depth 'were impacted twice as much' as those who touched on every major topic. The results conflict with the standardized tests that tend to assess a wide range of topics. Note that this study had students self-reporting the work they did in high school.
