The Construction And Application Of PBL Model In Middle School Chemistry Experiment Teaching

PBL, also is known as Problem-Based-Learning or ProblemOriented Learning, is a teaching model in which the students solve real problems together by means of cooperative learning group under the teacher’s guidance to build student’s flexible knowledge base, to improve the cooperative learning ability, problem solving ability and autonomous learning ability.Compared with the traditional teaching mode, PBL teaching mode change in learning objectives, learning process, students’ role, teacher’s role and the way of evaluation, etc. The concept of it conforms to our country that the current new curriculum reform pays attention to the cultivation of student’s ability of philosophy. From its formally until today, the theory of PBL has gradually perfect. PBL as a kind of teaching mode in our country foundation education course such as Chinese, Maths, Geography, History, Biology Disciplines have different levels of trying. And the application in the Chemical also can see a little bit. But the specific study of middle school chemistry experiment teaching has some deficiencies. By previous scholars study found that secondary school chemical experiment teaching present situation is not optimistic in our country. The new curriculum reform is just superficial or even completely ignored. So the purpose of this paper is to build an effective teaching mode that applicable to the chemistry experiment teaching. And applying it into the chemistry experiment teaching. Through it sought a new idea of chemical experiment teaching, improve the students’ learning atmosphere, improve the students’ experimental ability and all aspects of comprehensive literacy.In this paper, through the adoption of a variety of methods like literature analysis method, interview method, questionnaire survey method and statistical analysis method to complete the work and obtain the following research results.(1)The author wrote a literature review about the PBL teaching mode and expounds the connotation of it. And it also describes the research history and research status of PBL at home and abroad and the present application situation of the PBL teaching mode in the experimental teaching.(2)On the basis of predecessors’ research are perfected and improved. From the theoretical basis, teaching target, teaching program, implementation conditions and evaluation system in five aspects, build such a PBL teaching mode that could practice in the middle school chemistry experiment teaching.(3)In the paper in view of the four types of middle school chemistry experiment respectively used as construct the teaching mode, specific examples are given for reference.(4)In the middle school chemistry experiment class through the questionnaire survey conducted empirical research. PBL teaching model is verified by the results of it are viable.The study indicates that, Problem-Based-Learning used in middle school chemistry experiment teaching was conform to the concept of the new curriculum, and could effectively improve the students’ ability of autonomous learning, problematic consciousness, cooperation consciousness and the ability of chemical experiment.
