The Construction And Practice Of Pattern Of Biology Dialogue Instruction Based On The Task Lists

As a new dynamic teaching approach, dialogue instruction is becoming one of the latest focuses in the education field. However, as seen from literature, the specialized researches on the dialogue instruction are mainly theoretical, seldom based on experiments. Moreover, these researches mainly focus on literal arts teaching issues such as Chinese and English. The theory on dialogue instruction is inapplicable to the teaching reality in middle school. The application of dialogue teaching approach in biology instruction is limited by many factors. In this background this paper combining the study of theory with practice, does a further research on the biology dialogue instruction, aiming at constructing a new modern type of dialogue instruction with the task lists, establishing a relevant evaluation system, designing task lists of high quality, making the students study happily, thereby enhancing the effectiveness of classroom teaching biology.Following methodologies have been adopted in this study:content analysis, questionnaire survey, examination contrast, and case study, some of which are combined with each other when doing the research. This paper analyzes the situation of the dialogue teaching research, start from its not in high school biology teaching being implemented, as well as the problems of teaching high school biology, designs and distribute relevant questionnaires, constructs a mode of biology dialogue instruction with the task lists in middle school, carries out the mode, and refines the mode continually in practice. All the data are analyzed by the SPSS 11.5 and the following conclusions come out:It can raise the students' interest of biology study, create a class atmosphere of equality and democracy, enhance remarkably the students'subject consciousness, facilitate the development of students'innovative potentialities, cultivate the students'positive emotions and make students get a remarkably higher mark in tests.However, some problems have been found out during the research. Teachers have not changed their views of dialogue instruction and can not understand it thoroughly; apply the dialogue instruction blindly and ignore other modes of teaching which makes dialogues formalized and fake;. The students can not operate this mode freely. To the problems above, some suggestions are put forward:renewing the views of teachers by organizing teacher training and making lectures and so on; improving the qualities of teachers and their dialogue skill; combining the dialogue instruction with other modes of instruction; sticking to diversified criterion of evaluation.
