任務(wù)分析法在高中化學(xué)教學(xué)中的應(yīng)用
[Abstract]:As an important part of teaching design, task analysis can improve students' interest and improve classroom efficiency. The importance of task analysis has been recognized by more and more teachers and scholars. From 2000 to 2015, many researches on instructional design have applied task analysis theory and technology, but so far few researchers have used this theory and technology to guide chemistry teaching in senior high schools. Therefore, it is an urgent need to combine the theory and technology of task analysis with chemistry teaching in senior high school, so that the teaching of chemistry in senior high school has more abundant scientific theory guidance. In this study, the origin and development of the task analysis method are briefly described, and the corresponding psychological basis is expounded. Then, the application process of the task analysis method in the teaching process is summarized through the literature. By means of interview and questionnaire, the present situation of "task analysis" used by chemistry teachers in Qianjiang City, Hubei Province, was investigated. Based on the results of the investigation, two classes were selected in the second grade of senior high school for a one-semester comparative experiment, and the teaching design of "chemical balance" was designed, and the practical teaching effect of task analysis method was verified from many angles. The conclusion of this study is as follows: in the aspect of teaching effect, task analysis not only contributes to the improvement of academic achievement, but also contributes to the enhancement of students' interest in learning. As far as teachers' teaching is concerned, task analysis is helpful to the improvement of students' short-term and long-term achievement, and the longer the teaching time is, the more obvious the effect is. The innovation of this paper lies in the following: a comprehensive and systematic study on the present situation of task analysis is carried out, and the present situation of task analysis theory in the process of high school chemistry teaching is investigated by a large number of interviews and questionnaires, and the current situation of task analysis theory in high school chemistry teaching is investigated. This paper generalizes the process of task analysis comprehensively and meticulously, and carries on a semester of comparative experiment teaching, validates the effect of task analysis method, and gives a concrete teaching design case. The deficiency of this study is that the samples collected are relatively small, the number of experiments is less, only two classes in the second grade of senior high school are selected for the comparative experiment, and the universality of the experimental conclusion needs to be improved. At the same time, this study can also collect some foreign data and samples for comparative analysis.
