电子实验室减少脚手架的效果

Effects of Reducing Scaffolding in an Undergraduate Electronics Lab

Evan Halstead

摘要:

设计和科学研究被认为是本科物理实验室课程的关键组成部分。有鉴于此,许多成功的实验室项目已经开发出训练学生发展这些能力,这些项目的学生已被证明表现出更高的科学能力转移到新的情况。在本文中,我使用的数据,从电子类物理专业调查如何给学生设计电路的机会-从传统的食谱实验室指南删除步骤-影响学生的能力,以确定他们还没有见过的电路的功能。我比较了实验后测验的结果,从学生谁得到了明确的程序和那些学生谁得到了不完整的程序,我发现两组的结果没有统计学上的显着差异。我探讨了零效应的可能解释,并建议未来的研究方向。

英文摘要:

Design and scientific investigation are recognized as key components of undergraduate physics laboratory curricula. In light of this, many successful lab programs have been developed to train students to develop these abilities, and students in these programs have been shown to exhibit a higher transfer rate of scientific abilities to new situations. In this paper, I use data from an electronics class for physics majors to investigate how giving students the opportunity to design circuits --- by removing steps from traditional cookbook lab guides --- affects the students' ability to determine the function of circuits they haven't seen before. I compared post-lab quiz results from students who were given explicit procedures to those of students who were given incomplete procedures, and I found no statistically significant difference in the results of the two groups. I explore possible explanations for the null effect and recommend future research directions.
