Teaching for transfer
Sanjoy Mahajan
Students, after they leave our care, are called to solve the diverse problems of the world, so we should teach to increase transfer: the ability to apply fundamental principles to…
Estimating gas mileage: An example of order-of-magnitude physics
Sanjoy Mahajan
I discuss how to estimate the gas mileage of a car. This discussion, which covers air resistance and Reynolds numbers, describes one way to introduce dimensional analysis and order…
Is it time for a science counterpart of the Benezet-Berman mathematics teaching experiment of the 1930's?
Sanjoy Mahajan, Richard R. Hake
Should teachers concentrate on critical thinking, estimation, measurement, and graphing rather than college-clone algorithmic physics in grades K--12? Thus far physics education re…
Observations on teaching first-year physics
Sanjoy Mahajan
Highly successful students, as measured by grades and by scores on the Force Concept Inventory, still struggle with fundamental concepts in mathematics and physics. These difficult…
Introductory physics: The new scholasticism
Sanjoy Mahajan, David W. Hogg
Most introductory physics textbooks neglect air resistance in situations where an astute student can observe that it dominates the dynamics. We give examples from many books. Using…
