项目摘要

We implemented a computer tool to assist learners to collect and to process data for laboratory experiments on introductory physics courses. We used this tool to record learners' activity in a course, and analyzed the record to find problems. Found issues that are necessary for learners to be addressed are as follows; oversight of measurement parameters which may be caused by incomplete experiment plans, unnatural measured values which may be caused by inappropriate measurement, errors in calculation formula, inappropriate significant digits, etc.In order to detect these problematic states from information recorded in the data processing tool, we defined conditions and implemented an assistance module in the tool. Advice given to learners is classified into two categories. One is to prompt learners to correction in the middle of experiment because detected issues are essential. The other is to provide learners issues to discuss after the experiment. In order to give learners advice timely, the tool grasps progress of experiment from recorded information.To deepen discussion about results of experiment, it is sometimes necessary to collect data by supplemental experiment. But it is difficult in class because of time limitation. We realized a data sharing tool, with which learners retrieve other learner's data to compare their own results.

我们实施了一种计算机工具，以帮助学习者收集和处理有关介绍性物理课程的实验室实验的数据。我们使用此工具在课程中记录了学习者的活动，并分析了记录以发现问题。发现学习者所需的问题如下：对测量参数的监督可能是由不完整的实验计划引起的，可能是由不适当的测量引起的不自然测量值，计算公式的错误，不适当的数字的错误等。，我们定义了条件并在工具中实现了一个援助模块。给学习者的建议分为两类。一种是提示学习者在实验中进行纠正，因为检测到的问题至关重要。另一个是在实验后为学习者提供讨论的问题。为了及时向学习者提供建议，工具从记录的信息中掌握了实验的进展。为了加深对实验结果的讨论，有时有必要通过补充实验收集数据。但是由于时间限制，在课堂上很难。我们意识到了一个数据共享工具，学习者通过该工具检索其他学习者的数据以比较自己的结果。
