The Aarrangement Analysis Of Concept Learning Characteristics Of The America Junior High School Biology Teaching Material "Life Science"

As the reform of the course standard, teaching material is reforming too. The value of reform has been excavated, the selection of teaching material content has to adjust in the curriculum standard request. The higher correlation of the materials selection knowledge content and the basic concept, basic principle, the greater likelihood of migration in the mind of the students and its timeliness is more long, and the higher value development of student lifelong learning. To this, the teaching materials should be how to grasp the biology concept learning intrinsic psychological logic, which highlights the concept teaching, is worth our study. In this paper, based on the relevant theory of concept learning, aims to learn biology concept, core science textbooks for American high school life science for text analysis.The teaching materials from the multiple perspective aims introduct the concept. On the choice of titles at all levels, as much as possible to show more concept noun or phrase, highlight the internal relations between concepts; Through the "abstract", "the study focused on" columns, clear about the core concept, grasp the focus of the teaching material content; Through the "navigation experiment" columns, provide relevant concepts of perceptual knowledge, in preparation for concept generation; Through the study of "folding card" columns, provide relevant concept learning ideas, also provide guidance for concept generation; Prepared through "learning" to test the students of the related concepts of former concept, to prepare for the concept transformation, finally realizes the concepts generated.The concept of generation is a process of constantly strengthened. Example of concept definition, concept name, the acquisition of level should not only stay in the memory, because the ultimate goal of concept learning is to be able to apply. The teaching material through "chapter review" column to summarize learning concept and testing; Through the "study guides" concept, build a conceptual knowledge network; Through the standardized test in the problem sets to reinforce concepts, makes the concept of the generation, migration; Through the laboratory experiment", "family lab" columns to apply concepts, to solve problems in reality. American textbooks to grasp the concept of consolidation and application of the concept of the main method is realized through practice memory, testing the concept generation, and the concept of the migration guide etc. Also through to implement in the real situation so as to realize the application of the concept.In a word, the teaching material content arrangement to grasp the concept as the main line; follow the general process of concept learning; attach great importance to the highlights and transfer of concepts.
