The Strategy Research Of Analogy Method Applied To Scientific Conceptual Change Teaching In Junior High School

The concept of junior high school students’ scientific literacy teaching can effectively develop the education sector, has become one of the hot and everyone concerned about the topic. Conceptual teaching is the teaching of conceptual change, which is based on understanding the former concept of students, and gradually correcting, supplementing, improving and constructing new cognitive system.In the concept of junior high school science teaching, students do not have specific methods to understand the concepts, but do not know how to use their own thinking to deeply and contact, the analogy method using in the concept teaching is a kind of effective method. Analogy method is a scientific method which has a long history and has a great effect. It is mainly used in the scientific hypothesis, the establishment of the model and so on, has formed a set of perfect system. But junior high school science as the integration of the subject, the use of analogy to the concept of junior high school science teaching empirical research is less.This article through to the analogy method in the ordinary classroom teaching use question to carry on the analysis, summarized three aspects:because the concept is not clear; does not have the appropriate model; has the similar ratio but does not have the analogy. Then, five teaching strategies are summarized, which are to promote the change of concepts by analogy method:1. The basic steps of the analogy method of making full use of the analogy in the teaching material.2 to guide students to establish a model to stimulate students’ autonomy.3 in the scientific method to find the common, between the nature of science and technology.4 using life situation, combined with STSE teaching.5 interdisciplinary model, to play the advantages of integration. And based on the case analysis and practical exploration. Examples are from five aspects of physics, chemistry, biology, geography, the concept of the typical cases and the case were summary and promotion.The concept teaching is the teaching which has profound influence on the students’ daily life, study and life development in the future. The use of analogy in the concept of junior high school science teaching strategies, teaching design based on student’s original concept, can help students build knowledge system can be improved, and can continue to construct and perfect, so that let the students master the scientific understanding of the key!...
