A Study On The Teaching Strategies Of Chemistry Based On The Three-dimensional Objective

Education, in essence, is a realization of the activities of the value of human life. The basic idea Of China's new curriculum reform is "for the Chinese nation's revival, for each student's development". The new curriculum reform requires implementing the three-dimensional objective in practice. The subject focuses on the cultivating and pursuing of the perfect personality, attaches importance to the harmonious development of intellectual factors and non-intellectual factors, emphasizes on the organic unity of dedicatee's body spirit, emotion and intellect, as well as individual potential development. Chemical education is the science education, and the ideal science education should be harmonious between science logos and humanist spirit and should be the pursuit of truth, benevolence and beauty, meanwhile, the pursuit of the perfect human nature and social responsibility.At present, the new curriculum reform is in full swing. From the practice of curriculum reform, teachers' lack of theory and guide on implementing the three-dimensional objective has already become the main factor that impacts the effect of education teaching and student development. From the view of teaching research, current instructional theory can't offer the theory foundation of teaching strategies for integrated three-dimensional objective, and lack the study on teaching strategies of chemistry based on three-dimensional objective, as well as the effects of guiding and adjusting for practical teaching. Therefore, the selection of this study is to adapt the needs of curriculum reform and teaching in practice, with important theoretical significance and practical value.In this study, the research attributes the study of empirical based on theory, it's idea is from theory practice to practice and then back to theory. At first, we obtain the research question in practice by carrying out a field investigate, interviewing and taking a questionnaire investigation on teachers. Secondly, through theoretical research, we have explored the essence and connotation of three-dimensional objective as well as the sources of classification, and the theoretical foundation of the teaching strategies of chemistry based on three-dimensional objective. On the basis of theoretical research, the teaching strategies of chemistry based on three-dimensional objective has been formed, which provides a theoretical guidance for the following experimental method. At last, taking students in two parallel classes as subjects, we conduct an instructional experimentation which applies and validates the teaching strategies of chemistry based on three-dimensional objective.The dissertation consists of seven chapters.Chapter one is presentation of questions. The main content in this chapter is about research reason, meaning and problem. Through the investigation of the teaching strategical status of current chemistry teacher, the study finds out the concrete problems and puzzles faced by teachers, searches the practical source for the subject. and analyzes the desire of present police, economy, culture to education, clears era meaning of putting forward of three-dimensional objective in new curriculum reform.Chapter two is literature review. The chapter defines the concepts of three-dimensional objective and teaching strategies, reviews the research status of domestic and international research about teaching strategies of chemistry, and rethinks and looks forward to the existent questions.Chapter three is research design. The main content in this chapter is about research route and content, research method, research object, research reliability and validity, methods and process of collecting data, the process of tidying and analyzing data, and summarizes the prepare research process.Chapter four is theory research. The chapter studies the essence and the sources of the three-dimensional objective profoundly, the theory foundation of teaching strategies of chemistry based on three-dimensional objective, and integrate diversified theories with Wilber consciousness spectrum theotry.Chapter five is strategies research. The chapter is the method guide based on theory foundation. At first, the chapter offers the teaching strategies of chemistry based on three-dimensional objective. Secondly, the chapter studies about how to implement in a whole the three-dimensional objective of chemistry curriculum.Chapter six is experiment research. The study takes an experiment and validates the effect about the teaching strategies of chemistry based on three-dimensional objective in practice.Chapter seven is conclusion and suggestion. This chapter puts forward the summarize conclusion about the teaching strategies of chemistry based on three-dimensional objective, and some useful suggestions about new curriculum reform, the constructing of efficient classroom and teacher's professional development.The conclusions of the research are as follows:1. From the view of philosophy, psychology and pedagogic, the study demonstrates the nature of three-dimensional objective that is a whole and generalized knowledge concept, integrates the three major attributes of knowledge: objectivity, process, and dynamic.2. From the theory research, the study discovers the good teaching strategies lie to eliminate the boundary between the person and knowledge, knowledge's and knowledge and situation. That Wilber consciousness spectrum theory can integrate diversified theories, all of which construct the theoretical foundation of strategies based on three-dimensional objective. (1) knowledge and skill- the theory of generalized knowledge processing. (2) process and method- situated cognize theory. (3) emotion attitudes and values- the learning theory of humanism. (4) integrated education- brain-based education study.3. Based on the research of theory, the study put forwards some teaching strategies of chemistry based on three-dimensional objective. (1) knowledge and skill: the analyzing of chemistry knowledge type, the constructing of chemistry knowledge network, the representation and logic of chemical knowledge. (2) process and method: Situated design of chemical teaching, multiple-sense representation learning, the deep processing of chemical knowledge, science thinking guide in experimental teaching, the arrange of primacy-recent effect. (3) emotion attitude and values: the strategies of emotion attitude and value education etc..4. The study verifies the relativity among the three-dimensional objective, and establishes the relation structure of three-dimension objective of chemistry curriculum through the instructional experimentation.5. The study constructs the square matching relation between three-dimensional objective and teaching strategies of chemistry through the instructional experimentation.6. Instructional experimentation shows that the teaching strategies of chemistry based on three-dimensional objective can promote students overall development remarkably in knowledge and skill, process and method, emotion attitude and values.The innovations of this research are as follows:1. From the view of philosophy, psychology and pedagogic respectively, The study demonstrates the nature of three-dimensional objective is a whole and generalized knowledge concept, and it integrates the three major attributes of knowledge: objectivity, process, and dynamic.2. Wilber consciousness spectrum theory integrates these theories' distillation which includes the theory of generalized knowledge processing, situated cognitive, humanistic learning and brain-based education study, and offers the teaching strategies of chemistry based on three-dimensional objective on the basic of these theories.3. The instructional experiment verifies the relativity of three-dimensional objective, constructs the relation structure of three-dimension objective of chemistry curriculum, and the square matching relation between three-dimension and teaching strategies of chemistry, validates that teaching strategies of chemistry based on three-dimensional objective can promote student's overall development in knowledge and skill, process and method, emotion attitude and values remarkably.The study can offers some basic operational methods for new curriculum teaching strategies of chemistry, and provides relevant direction for the implementation of foundation education curriculum reform idea in practice of chemistry class.
