Research On The Cultivation Of The Basic Chemistry Concepts For Middle School Students

"Students development-orientied" is the the core idea throughout the basic education curriculum reform . The middle school chemistry curriculum and teaching basic science education, as an important component part should focus on the training and development of the thinking ability of students basic concepts and discipline for students to establish a scientific world outlook and methodology lay the foundation. As a high school chemistry teaching under the guidance of practice, from the traditional "knowledge-based" to the "concept-oriented" is the development of the times on personnel training to the inevitable requirement.In this paper, the basic concept of middle school students to train on the topic of basic concepts of the chemical characteristics of the connotation, as a learning value formation process, training in areas such as strategy, and explains, the specific chemical clarify how the basic concepts with the progress of teaching the and gradually revealed by the sound. A total of nine papers, including part of the following major elements:The first part, first of all clarify the reasons for the choice, pointing out that the basic concept of training students lifelong students of the need for developing a scientific nature of the needs of education, the implementation of the new teaching objectives.The second part, the purpose of this study was, and tasks.The third part, the basic concept of culture of chemical synthesis. On the basic concepts at home and abroad chemical training with the theories developed in the past, which absorbed the essence of reference, expand its research ideas.Part IV, chemical basic concepts culture of the theoretical foundation. This paper discusses the theory of constructivism and Bruner's "academic structure," the major theoretical viewpoints and train students on the basic concepts of the Enlightenment, so as to "concept-based" teaching to provide theoretical support.Part V, chemical content of the concept of basic features and contents of a. Chemistry is the basic concept of middle school students in the system learning courses on the basis of chemical formed by the chemical views and the overall general awareness of the specific performance for individual initiative and chemical use chemical knowledge thinking, methods and the things around inspection deal with the problem of consciousness or thinking habits, it is generally strong and the applicability of the follow-up to the individual development of standards and guidance role. Chemical basic concepts into specific elements of the concept of particulate concept, the role of particulate material of the structure, material changes in the concept of classification of substances and chemical values, and each has its own idea of a specific meaning.Part VI, chemical basic concepts and specific knowledge of the relationship between the levels of development and perspective. Chemical basic concept is the refining and chemical knowledge distillation, chemical knowledge is a basic chemical building tools and the concept of vector. Chemical basic concepts can be divided into different stages of development, is accompanied by specific knowledge of teaching gradually from fuzzy to clear, from low level to high level and deposition was revealed by the students in the educational function generated. Chemical concepts of various levels of development perspective of the study is that part of this paper as well as the most carefully written one.Part VII, discusses the basic concepts of science learning value. Mainly reflected in two aspects: Chemical basic concepts to enrich and develop the middle school students, dialectical thinking;Chemical basic concepts led the development of scientific literacy.Part VIII, the basic concept of the formation of the chemical process and influencing factors. Part of the mechanism of human development of knowledge on the basic concept of the formation of the chemical process, specific knowledge to the core concepts from the core concept of the basic understanding, and to the ideas and methods of control and application of cognitive structure and the improvement of chemical, the students Chemical thinking ability will move the process of deepening their understanding of the concept level reached. Finally, both internal and external factors affecting the chemical on the basic concept of the formation of various factors. Part IX, the basic concepts of training strategies and evaluation methods. The first part of the culture of middle school students basic concepts of the feasibility of the proposed "concept-based" instructional design procedures, as well as specific teaching strategies, students are given an evaluation of the basic concept of building methods, the concept-based Chemistry Teaching regulations.In this paper, the main innovations embodied in the following three aspects: First, a clear definition of the basic concepts, features and content of basic meaning of the basic concepts of a student in the specific field of vision is, in concept-based teaching , and promote the development of thinking ability of students to provide a theoretical basis. Second, the knowledge of secondary school chemistry curriculum content, the concept of the development of various chemical gradient for the perspective. For the overwhelming majority of middle school chemistry teachers to choose, the use of chemical-specific knowledge, the concept-based teaching to provide a realistic basis.Third, from the theory and practice of perspective, the proposed concept-based instructional design procedures, as well as basic concepts of the specific training strategy, concept-based secondary school chemistry teaching more operable.
