| Constructivist theory of teaching thinks that student learning is the construction of scientific concepts in nature, the user of scientific knowledge.The meaning of scientific concepts enables students to understand better the nature of things and phenomena, the promotion of scientific knowledge, systematic and structured, help students develop logical reasoning, improve the scientific literacy of students. Thus, in the teaching process we should design in accordance with the laws and students to study the diversity of psychology teaching activities, as much as possible to enlighten the students thinking, to enhance students understanding of science concepts and understanding of the level of construction to avoid the mechanical memory of scientific knowledge.This article is in the constructivist theory of teaching under the guidance of the specific tasks for the investigation report, the author attempts to survey line through the teaching of "original battery" taken in the course of the contents of specific strategy, through interviews, exchanges and other means, comparing different specific effects of different teaching strategies to optimize the combination to achieve the ideal for the purpose of teaching strategies.Through research showed that:different teaching strategies will produce different teaching effectiveness. Traditional teaching strategies mode of teaching activities, the students have some knowledge of the role of the implementation, but the students response capabilities in the obvious flaw; the application of multimedia teaching strategies so that students interested in learning knowledge has improved, the capacity of the classroom increased a lot, and the intuitive knowledge of the microstructure, appropriate difficulty of reducing the knowledge to facilitate students to accept. But the problems is that some students of the attention was attracted by the modern teaching methods, not only did not meet the expectations of teachers, but the effect of the teaching; concept-based teaching strategies from the Perspective of the use of the concept of the electrochemical were introduced to the teaching so that students in learning the knowledge that part of the electrochemical formation of a clear idea of the time, the battery works from the original level constitutes a practical understanding of the original battery, works. And thus achieve self-sufficiency learning, develop capacity of the teaching purpose. However, the use of this kind of teaching strategies and understanding of students subject to acceptance. For a large class of students composed of different classes, is not particularly adapted to the methods.Through this research, we can see that teaching strategies each has its own advantages, there are some defects more or less at the same time, teachers should base on the actual situation of students to choose appropriate selection of appropriate teaching strategies for teaching. |
