The Design, Development And Testing Of The Prototype Of The Problematic Teaching Design Automation Tool For Primary And Middle School Teachers

In the information age,learners are required to have innovative ability and advanced thinking ability.In order to achieve this goal,traditional teaching methods need to be reformed.Education should stimulate students’problem awareness and improve their ability to solve problems,so as to cultivate high-quality talents required by the era.As a model that can effectively stimulate students’interest in learning and improve their ability to solve problems,problem-based teaching has been recognized and praised by various fields.But in educational works,the question teaching pattern has the implementation difficulty to be big,the work load is heavy,time-consuming and so on the question.If we want to improve teachers’working efficiency in the problem teaching mode,we should provide support and help in the problem teaching design.With the ideas of the teaching design automation problems combining the teaching design,the development of a problem of teaching design automation tools can be implemented,not only can provide guidance for problem of teachers’teaching design,also be able to upgrade the accuracy and effectiveness of the problems in teaching design,so as to help teachers design a scientific and reasonable and efficient problem teaching design scheme.The research through the teaching design automation,the problem teaching and user-centered design method of the research status at home and abroad,summarized the current research in the field of design automation teaching shortcomings,at the same time,the problems in the research of this teaching concept defining,and user-centered design method of concrete steps are clear.Taking the teaching design automation thought as the theoretical guidance,using the user-centered design method,combining the basic elements and processes of the problem teaching design and the results of the user demand analysis,a prototype that can assist teachers to carry out the problem teaching design is designed.The prototype reappears every step of problematic instructional design and sets a selection box in some locations,aiming to help teachers sort out instructional design ideas through instructional design tips.Meanwhile,it can also help teachers consolidate their knowledge of instructional system design and improve their ability of problematic instructional design.The prototype in this study underwent three iterations of design and development,including two user tests.(1)initial development:the initial development of the prototype is carried out according to the relevant knowledge of problem-based instructional design and the results of user demand analysis.(2)secondary development:the first round of usability test is conducted with the prototype developed for the first time,and the test methods are usability observation test and user interview.The data results in the usability observation test record form are used to record the parts where users have problems.At the same time,the Suggestions and opinions put forward by users are summarized according to the interview results of users.Based on this,the secondary development is carried out.(3)three times of development:the second round of usability test is carried out with the prototype developed in the second round.The method adopted is the same as that adopted in the first round of test.The problems in the second round of usability observation test record table and user interview record table are sorted out,and the prototype is developed in the third round.By sorting out the test results of the two rounds,it is found that the prototype mainly provides users with effective help in the following aspects:(1)it provides a reasonable design framework for teaching objectives;(2)accurate teaching problem determination steps are provided;(3)it presents a clear way of organizing teaching problems;(4)provide guidance on the framework of problem activities;(5)provide a complete teaching design framework.After three iterations of the design and development process and two user tests,the conclusions of this study can be summarized as follows:(1)the prototype developed in this study can be friendly and usable;(2)the prototype can provide help for teachers to carry out problem-oriented teaching design;(3)the prototype improves the efficiency of teachers’ teaching design;(4)the prototype improves teachers’ teaching design ability.
