Applied Research On Cooperative Learning About Chemistry In Senior Middle School

With the development of the times and the further improvement of quality-oriented education,especially the full implementation of new curriculum reform in senior middle school in our country,the existing problems in the course of education in middle school are becoming more and more prominent.The investigation results from Division of Basic Education in Ministry of Education shows that the main characteristic of teaching and learning style in basic education is passive acceptance,and the chemistry education in senior middle school is no exception.In recent years,although the education reform in middle school has developed a lot,there are still many prominent problems.For example,in the aspect of teaching methods,the teaching style of one-way transmission is still relatively common,which takes teachers' instruction seriously but despises students' self-construction.In the aspect of teaching goals,it attaches importance to cognitive objectives but slights affection objectives,so the development of students' potential has been restricted,the power of the power system of students' learning is insufficient,as well as students are lack of cooperative awareness and cooperative skills in particular.It doesn't agree with our information age that needs cooperative awareness and social skills,and it is not conducive to the cultivation of students' innovation ability and the improvement of students' quality.In the aspect of teaching evaluation,it minds results but looks down on process, emphasizes competition excessively but despises cooperation,concerns a small number of top students only but lets most students play a failure role in accompanist,so that the self-esteem and learning initiative of most students are hurt.One of the key points of the new round of curriculum reform is to study how to promote changes in students' learning styles,as well as initiate self-learning,cooperative learning and inquiry learning,so that,there will be a substantive change in students' learning styles. Highlighting the concept of humanistic education,cooperative learning considers the improvement of human relations in teaching to be a breakthrough point,takes the development of human resources in teaching as a focal point.By creating a learning environment with multilateral interaction and freedom,cooperative learning fully mobilizes the students' enthusiasm to join in the learning process actively,so that, students can form the learning style of self-construction and the modern consciousness full of participation,co-operation,competition,as well as association.Therefore,it makes students obtain a positive and profound experience,promotes the development of students' cognitive level,social skill as well as social emotion,and comprehensively improves the quality of students.This study,combined with the characteristics of chemistry discipline in senior middle school and through the discussion to practical problems in cooperative learning, builds a model of cooperative learning about chemistry in senior middle school,which is more reasonable and easy to operate.So that it can provide practical guidance for the effective implementation of cooperative learning on chemistry education in senior middle school and the comprehensive improvement of students' quality,and promote the development of the new round of chemistry curriculum reform,sparing no effort.This paper is divided into seven parts:The first part,which is the part of introduction,briefly describes the backgrounds and basic problems of the study as well as its significance.In the second part,the paper traces to the history source of cooperative learning and defines its connotation.In the third part,the paper carries on analysis and research from the four aspects of cooperative learning,which are its theoretical bases,classification,nature and philosophy. In the fourth part,the paper concludes and analyzes the existing problems in implementing cooperative learning,and based on this,it comes up with strategies to them.The fifth part,which is based on the practice in the case of cooperative learning on chemistry education in senior middle school,builds a more reasonable and easy-to-use model of cooperative learning.The sixth part carries on an experiment research to the model of cooperative learning on the chemistry in senior middle school.The seventh part is the conclusion of the paper.
