学生对Direct电流阻性电路的理解
Students' Understanding of Direct Current Resistive Electrical Circuits
摘要：
研究表明，高中生和大学生关于直流电阻电路的推理模式往往与目前接受的解释不同。目前，在电路中没有标准的诊断检查。两个版本的诊断仪器称为确定和解释电阻电路概念测试（直接），每个由29个问题。考试提供的信息为课堂教师提供了一种手段，用以评估学生的进步和概念困难以及他们的教学方法。它可以用来评估课程包和/或其他补充材料的有效性，在克服学生的概念困难。分析表明，学生，特别是女性，往往持有多种错误的概念，即使在教学。在采访中，电池是一个恒定的电流源的想法是最经常用来回答问题。学生们在解题时往往把注意力集中在电流上，并混淆术语，经常把电流的性质归结为电压和/或电阻。结果显示学生对电路现象的基本机制没有清楚的了解。另一方面，学生能够轻松地从电路的“现实”表示转换为相应的原理图。
英文摘要：
Research has shown that both high school and university students' reasoning patterns regarding direct current resistive electric circuits often differ from the currently accepted explanations. At present, there are no standard diagnostic examinations in electric circuits. Two versions of a diagnostic instrument called Determining and Interpreting Resistive Electric circuits Concepts Tests (DIRECT) were developed, each consisting of 29 questions. The information provided by the exam provides classroom instructors a means with which to evaluate the progress and conceptual difficulties of their students and their instructional methods. It can be used to evaluate curricular packages and/or other supplemental materials for their effectiveness in overcoming students' conceptual difficulties. The analyses indicate that students, especially females, tend to hold multiple misconceptions, even after instruction. During interviews, the idea that the battery is a constant source of current was used most often in answering the questions. Students tended to focus on current in solving the problems and to confuse terms, often assigning the properties of current to voltage and/or resistance. Results indicated that students do not have a clear understanding of the underlying mechanisms of electric circuit phenomena. On the other hand, students were able to translate easily from a "realistic" representation of a circuit to the corresponding schematic diagram.
