THE GRAPEVINE

Students, eat your breakfast! That's the advice from Annemarie Boschloo and six colleagues at the University of Amsterdam based on their study of 605 adolescents. They find that, after controlling for a variety of other variables, those who habitually skip breakfast have significantly lower grades than those who eat breakfast daily. The results hold regardless of age or gender, and regardless of whether the student is judged to be a "morning person" or an "evening person." See "The Relation Between Breakfast Skipping and School Performance in Adolescents," Mind, Brain, and Education, 6 (June 2012): 81-88.

Sharmistha Self of Missouri State in Springfield examined the influence of the attendance policy in the principles of macroeconomics class. After controlling for other relevant factors, she found "strong support" that having an attendance policy reduces absenteeism. What's more, a policy that penalizes students for missing class is more effective than one that rewards them for good attendance. Fewer carrots, more sticks. See "Studying Absenteeism in Principles of Macroeconomics: Do Attendance Policies Make a Difference?" Journal of Economic Education, 43 (July-September, 2012): 223-234.
