Abstract
Background: Software testing is a common course in universities. It mainly explains the principles and methods of software testing and the use of testing tools. It is committed to develop software testing talents. At present, some urgent problems have appeared in the course of software testing. For example, teaching content lacks practical ability, students’ interest in learning is not high, personnel training has far behind market lags demand. TPACK is a subject teaching knowledge of integrated technology, which was proposed by American scholar Kohler and Mishra on the basis of the subject teaching knowledge. To research on TPACK, domestic and overseas scholars have taken up large number of theoretical and practical since 2005. Through research, it is agreed that the study of TPACK can improve the ability of teachers to master and use information technology. For the problems in software testing course, TPACK is introduced to improve it.
Methods: According to the existing teaching methods, a mixed teaching model using TPACK (MTMTPACK) is proposed in this paper. Combined with the three basic elements of TPACK framework and the characteristics of four compound elements, this mode is deeply integrated into the software testing course. Moreover, TPACK's learning ideas have been creatively put forward. In the MTM-TPACK teaching mode, it not only utilizes multimedia, network learning, WeChat and other ways are used to enhance students' interest in learning but also adopts some teaching method (such as case teaching method, task driven method and so on) to improve students’ enthusiasm and initiative in learning. In this way, students not only can fully participate in the teaching process of software testing, and their learning effect can also be improved at the same time. In order to compare the test results, a statistical method is introduced to analyze the experimental results.
Results: The reform of most teaching methods focuses on one aspect of improvement. The improvement of the MTM-TPACK teaching mode is aimed at the whole process. In the teaching effect between the experimental class and the ordinary class, the whole process of the test is designed. Through the methods of questionnaire survey and data collection, the test data were sorted and analyzed. The test results were compared in five aspects, such as score results, students' practical learning ability, knowledge expansion ability, learning interest and satisfaction, communication and team cooperation. The test results show that the new teaching method is superior to the traditional teaching method in terms of indicators.
Conclusion: This paper presents a mixed teaching mode in software testing course. This mode solves the problems in current software testing teaching, for example poor teaching effect. It not only improves the comprehensive quality of students' practical operation ability and teamwork ability, but also provides good conditions for students to engage in software testing. The method proposed in this paper lays a solid foundation for their future development, which can be applied to the practical courses of computer science and can contribute to the improvement of computer majors' practical ability.
