学生对牛顿第三定律理解的波动

Fluctuations in Student Understanding of Newton's 3rd Law

Jessica W. Clark, Eleanor C. Sayre, Scott V. Franklin

摘要:

我们目前的数据从学生之间的研究,学生对牛顿第三定律的问题,整个学年的反应。这项研究在罗切斯特理工学院进行,涉及三个季度序列中的第一个和第三个学生。反应曲线的构建揭示了学生学习中的微妙动态,而不是简单的前/后测试。我们发现直接指导有显著的积极影响,在部队的指导结束时达到顶峰,到季度末就会减少。两个季度后,在物理学III中,当指令从电力和电场的矢量量改变为电势的标量时,正确反应出现了显著的下降。然而,一旦教学回到涉及磁场的基于矢量的主题,学生的反应就会反弹到初始值。

英文摘要:

We present data from a between-student study on student response to questions on Newton's Third Law given throughout the academic year. The study, conducted at Rochester Institute of Technology, involved students from the first and third of a three-quarter sequence. Construction of a response curve reveals subtle dynamics in student learning not captured by simple pre/post testing. We find a a significant positive effect from direct instruction, peaking at the end of instruction on forces, that diminishes by the end of the quarter. Two quarters later, in physics III, a significant dip in correct response occurs when instruction changes from the vector quantities of electric forces and fields to the scalar quantity of electric potential. Student response rebounds to its initial values, however, once instruction returns to the vector-based topics involving magnetic fields.
