初中科学课堂教学有效性的研究与实践

初中科学课堂教学有效性的研究与实践
摘要：自新课程标准实施以来，无论是刚刚踏上工作岗位的年轻教师还是经验丰富的老教师都陷入了如何实施高效率教学的困境中。然而，教育工作者对初中科学课堂教学有效性的研究并不多见，其一是因为初中科学所涉及的内容极其广泛包括物理、化学、生物、地理、天文等给研究带来了一定的难度。此外，课堂类型多样性比如有综合课、互动课、开放课、实践课等等造成各个类型的课堂有效性标准不尽相同，因此对本课题的研究和实践都带了一定的困难。为使教师在改变教学方式的同时，提高教学有效性，促进教师从理论和实践的角度充分认识新课程的理念，改进教学模式，提高教学的有效性，使学生在课堂上学习知识之外也能有所发展，培养符合社会要求的科学人才，使师生共同进步。笔者从浙教版初中自然科学教材特点、初中学生特点、提高初中科学课堂教学有效性等方面进行研究，并提出初中课堂教学有效性的指标。解决了浙教版初中自然科学新课程实施过程中出现的一些现象和问题，并联系实际，以理论作为指导，以浙教版初中自然科学中“物质的溶解性”为例进行教学。

Study and practice on the effectiveness in the junior science  teaching
 
Abstract：In recent years, since the implementation of The new curriculum standards, whether young teachers or experienced senior teacher falls into the dilemma of high-efficiency teaching, and with the voice of “efficacious class", "effective class" is growing a variety of teaching models have been explored and practiced. Although the diversification of implementation of teaching methods provide more opportunities and platforms for us to do research of this topic, the study of this topic is still on exploration stage for the effectiveness evaluation of science teaching in middle school is not clear. Science teaching in middle school including physics, chemistry, biology, geography, astronomy and that sets difficulty for research. And it is difficult to do research and take practice for this topic for there are so many class types, such as integrated lessons, interactive classes, open classes, practical courses.

Key word:  classroom teaching, junior science , effectivity
