The Application Of Task Analysis In Senior High School Chemistry Taeching

Task analysis as a teaching an important part of the design, it can improve students’ interest and improve classroom efficiency, its importance has been more and more teachers and scholars realized. The study found online in Chinese art from 2000 ——2015, the instructional design studies many of which are applied to task analysis theory and technology, but so far very few researchers using this theory and techniques to guide the high school chemistry Teaching. So the theory and technology high school chemistry teaching task analysis combine to make the high school chemistry teaching richer scientific theoretical guidance become a pressing need.The study first outlines the origin and development of task analysis method, it described its corresponding psychological basis, and then summed up the task of literature analysis application process in the teaching process. By using interviews, questionnaire form, QianJiang City, Hubei Province for teachers to use chemical status of "mission analysis" conducted a survey in teaching. Based on its findings, in sophomore year selected for a period of two classes a semester comparative experimental study, we designed the "chemical balance" instructional design, from many angles to verify the actual task of teaching effectiveness Analysis. Conclusions of this study are the following points:(1) Teaching effect, task analysis may not only help to improve academic performance, but also help students to enhance students’ interest in learning.(2) For teachers, task analysis can help students improve grade of the short-term and long-term, and adhere to the longer, the more obvious effect.The innovations that:For the analysis of previous studies on the status of tasks carried out a comprehensive study of the system, through a lot of interviews survey the status of task analysis theory in the current high school chemistry teaching process, a comprehensive and detailed outlines the process of task analysis, and compared the experimental teaching a semester validation task analysis results, and given the specific instructional design cases.Shortage of this study was collected sample is relatively small, relatively small number of experiments, selected only two classes sophomore year comparative experiment universality of the conclusion to be improved. Meanwhile, the study also can re-gather information and sample some foreign comparative experimental analysis.
