罗马尼亚学生和美国学生处理机电物理问题的风格比较
A comparison between the styles Romanian and American students use to approach an E&M physics problem
摘要：
虽然物理在世界范围内都是一样的，但属于不同学习体系和不同文化环境的学生可能会发展出不同的处理和推理物理问题的风格。在第一个实验中，我们比较两个不同的学生群体之间的学生物理问题解决的风格：一组典型的美国学生（从俄勒冈州立大学微积分为基础的入门课程）和一组罗马尼亚学生（从布加勒斯特大学二年级班）。我们讨论的问题之一，在一个简短的E&M的调查，在这两个人口的学生提出了一个点电荷在一个区域包含一个统一的磁场。我们要求学生确定不同初始条件下电荷所受的力。在第二个实验中，三名美国物理系学生和三名罗马尼亚物理系学生被问到同样的问题，并被要求大声解释他们对每个问题的答案。他们的回答被录音了。学生的答案取决于对洛伦兹力的理解和他们对经典力学的一般知识。观察到的相似性和差异，这些学生群体之间的方法进行了讨论，我们的研究结果进行了说明。
英文摘要：
Although Physics is the same worldwide, students belonging to different learning systems as well as different cultural environments may develop different styles of approaching and reasoning out Physics problems. In a first experiment we compare student physics problem-solving styles between two different student populations: a group of typical American students (from an OSU calculus-based introductory course) and a group of Romanian students (from a second-year class at Bucharest University). We discuss one of the problems given in a short E&M survey, in which students from both populations were presented with a point charge in a region containing a uniform magnetic field. We asked students to determine the force on the charge for different initial conditions. In a second experiment, three American physics students and three Romanian physics students were given the same problem and were asked to explain loudly their answer to each question. Their answers were tape-recorded. Students' answers depend on an understanding of the Lorentz force and their general knowledge from classical mechanics. Observed similarities and differences in approach between these student groups are discussed, and our study's results described.
