Research On The Teaching Design Of Middle School Learning Course

The new Curriculum Form has raised the upsurge, but in the actual, due to various objective reasons, we did not pay attention to the reform of chemistry exercises teaching.This research will based on the investigation of the chemistry exercises teaching present situation, systematic and comprehensive analysis function, characteristics, and classification of chemistry exercise class, for the subject of Chemistry presents the basic requirements of chemistry exercises teaching design:pay attention to the three-dimensional target and teaching system structure outstand the Students 'Subjectivity, focus on optimizing the habits of thinking. Construct a chemistry exercise class design basic links which can operation of strong, easy to grasp and implement, mainly from the analysis of the clear teaching objectives, selection design of chemistry exercises, exercises explain strategy, rethinking teaching evaluation exercises four aspects to carry on the elaboration,highlighting chemistry exercises class design of the core-- exercises design and selection,in order to give full play to the exercises lesson inherent value, enhance the effect of teaching chemistry exercise class.The determination of teaching objectives should be based on the curriculum standards and the existing knowledge and experience of the students, the teaching content should be taken into consideration. Exercise selection is the primary basis is conform to the requirements of the teaching goal, but also pay attention to choose students error prone exercise, study emphasis and difficulty of teaching, exploring space. According to the selected choice exercises feature selection exercise teaching strategies, such as exposure students error prone points, cause cognitive conflict and methods as the core breakthrough teaching difficulty. Finally, the reflection and evaluation exercises teaching, improve teaching.This study is based on the basic theory of the teaching design, designed the teaching case of "redox reaction" exercise class. And do the practice of teaching, the experimental class and the control class were studied to test the effect of the teaching. The practical results show that the teaching design is advantageous in the mastery of students' knowledge, analysis and problem solving ability raise.
