摘要

This study evaluates the effectiveness of an on-line adaptive training system aimed at improving students' abilities to solve physics problems. The system displays a set of multiple-choice problems along with the correct answer and several carefully designed distracters. The distracters correspond to typical mistakes that undergraduate students make according to the authors' teaching experience. Depending on students' choices, the system provides them with appropriate, timely feedback and prompts them to solve other problems to practise their problem-solving skills further. In this way students solve a different set of problems of different difficulty levels according to their particular learning needs. The system also has the capability of providing other didactic resources such as tutorials or virtual learning environments, such as active simulators, to enhance student learning. Owing to its flexible structure, the system allows for the sharing of test banks and didactic resources between different courses and professors. It also keeps track of student performance and generates specific reports. The software was tested using a sample of 169 undergraduate engineering students taking physics courses. Using a pre-testlpost-test assessment tool, it is found that students using the software (the focus group) have a larger average integrated learning gain than students who did not use it (the control group). This conclusion is supported by a statistical analysis based on Z tests.
