Junior Middle School Chemistry Teaching Practice Research Based On The Constructivism

Things always cannot leave from the restriction and influence made by external environment factors and internal movement essence and regularity,In the process of development, there are always inevitably come with some things neither fit the external environment,conditions, demand, nor coordinate with their own internal factors such as movement and change, this time the way of change is needed to find a new balance and coordination.Began in 2001, this round of curriculum reform(generally considered as the eighth elementary education curriculum reform Since the founding of “New China”),It is based on the observation and thinking of international and domestic forms, combined with the rule and essential of education and teaching itself, designed to improve education quality of teaching and talent training for an innovative measures."Subject teaching" is one of the main platforms of education and teaching reform and the implementation method, chemistry as a backbone course during the junior middle school stage, has an important position and value of education in the stage of basic education.The success of the discipline teaching reform and exploration will effectively promote the process of the curriculum reform and development.Constructivism, as a kind of philosophy and epistemology genre,as a way of human understanding and explaining the world, is applied to teaching, has a strong impact, the viewpoint and method can promote the development and change of the way of teaching, in turn, it affect the cultivation of the talent, has undeniably important value and significance.This paper is the study to apply constructivism theory in junior high school chemistry teaching practice.From reading literature,grasp learning constructivism theory and reference, on the basis of existing research, combined with the method of questionnaire, interview method, classroom observation and other methods, and then carried out the concept and essential knowledge of constructivism and constructivism teaching theory, junior middle school chemistry teaching design and teaching instance design research based on constructivism, research of junior high school chemistry classroom teaching based on constructivism and the teaching effect,etc.The inspection of the teaching effect from this study mainly from three aspects:Theharvest of students’ basic knowledge and skills from chemistry learning, the change of chemical learning behavior,and the change and development of students’ chemistry learning emotion and attitude.Through the analysis of classroom teaching and the teaching effect, it is concluded that the junior middle school chemistry teaching practice based on constructivism, to a certain extent, can promote the development of most of the students’ "knowledge and skills", can achieve the change of most of the students’ learning behavior and way, it also has a positive function for the development of students’ chemistry discipline emotion and attitude, for the will of chemistry learning(willpower) of cultivating and strengthening.Also found that junior middle school chemistry teaching practice based on the constructivism,in promoting the development of each student, the effect is not the same.A kind of teaching mode sometimes dose not harmonious with students’ existing structure of "know", "background" and "personality temperament" and so on,there are certain connections, this link may be a problem such as "mutually exclusive", as a result, this paper also puts forward some new problems to be studied in the future.Limited to the actual condition of teaching and research, this study itself has some limitations, such as: no "control group", can’t compare research problems.To these problems, the author will continue the study when the conditions permit,and will constantly get more reliable conclusions, just as advocated by constructivism, the conclusion is only a kind of temporary and reveal interpretation...
