Lindsey, Beth A.; Stetzer, MacKenzie R.; Speirs, J. Caleb; Ferm, William N., Jr.; van Hulten, Alexander – Physical Review Physics Education Research, 2023
In this paper, we seek to evaluate the extent to which students can follow a deductive reasoning chain when it is presented to them. A great deal of instruction in introductory physics courses is centered on presenting students with a logical argument that starts from first principles and systematically leads to a particular conclusion. This…

Mohazzabi, Pirooz – Physics Teacher, 2018
In an article in this journal, it was shown that air resistance could never be a significant source of error in typical free-fall experiments in introductory physics laboratories. Since projectile motion is the two-dimensional version of the free-fall experiment and usually follows the former experiment in such laboratories, it seemed natural to…
