We study whether raising instructional time can crowd out student pro-social behaviour. To this end, we exploit a large educational reform in Germany that has raised weekly instructional hours for high school students by 12.5% as a quasi-natural experiment. Using a difference-in-differences design, we find that this rise has a negative and…

This article presents a mathematical algorithm that relates student achievement with directly observable, quantifiable teacher and student behaviors, producing a modified form of the Walberg model. The algorithm (1) expands the measurable factors that comprise the quality of instruction in a linear basis of research-based teaching components and…

Many professors who have ventured into online education are finding that shorter, modular clips are a more successful teaching approach than traditional 50-minute lectures. The author cites educators from several institutions who have adapted smaller, 15-20 minute instructional units originally developed for online courses, to their face-to-face…
