【摘要】：在长期的教学实践中,教育工作者一直追求的是高效的课堂教学。怎样提高课堂教学的有效性,改善课堂教学质量是当前的研究热点。化学实验是化学教学内容的重要组成部分,是化学学科最现实、最形象、最生动、最有效的教学载体。虽然有关有效教学和化学实验教学的文献资料很丰富,但从有效教学的角度对初中化学实验进行的研究方面却很少。基于此,笔者决定开展初中化学实验有效性教学的研究。本研究课题立足于新课标,在有效教学和建构主义、先行组织者的理论指导下,结合有效教学的诸多定义中存在一些共性的内容,从教师的教学行为要促进学生的发展这个角度出发,对初中化学实验有效教学进行界定。通过对学生展开问卷调查了解目前初中化学实验教学的现状,并从学生的学习情况和教师的教学情况两个维度分析调查结果,总结阻碍实验教学达到预期目标的因素,有针对性的提出相应的策略：探究性实验及时化、“灌输式”向“启发式”实验教学模式转变、实验方案优化、实验生活化、有选择的使用多媒体技术、开展多元的评价等,应用相应的教学策略来提升初中化学实验教学的有效性。
[Abstract]:In the long-term teaching practice, educators have been pursuing efficient classroom teaching. How to improve the effectiveness of classroom teaching and improve the quality of classroom teaching is the current research hotspot. Chemistry experiment is an important part of chemistry teaching content, and it is the most realistic, vivid, vivid and effective teaching carrier of chemistry subject. Although the literature about effective teaching and chemical experiment teaching is very rich, there are few researches on junior high school chemistry experiment from the point of view of effective teaching. Based on this, the author decided to carry out a study on the effectiveness of junior high school chemistry experiment teaching. This research subject is based on the new curriculum standard, under the guidance of effective teaching and constructivism, leading organizer, there are some common contents in many definitions of effective teaching. From the point of view of teachers' teaching behavior to promote the development of students, the effective teaching of junior high school chemistry experiments is defined. The present situation of chemistry experiment teaching in junior high school is understood through the questionnaire survey, and the investigation results are analyzed from the two dimensions of students' learning situation and teachers' teaching situation, and the factors hindering the experiment teaching to reach the expected goal are summarized. Some corresponding strategies are put forward: timely transformation of inquiry experiment, transformation from "infusion" to "heuristic" experimental teaching mode, optimization of experimental scheme, adaptation of experiment life, selective use of multimedia technology, and development of pluralistic evaluation, etc. The application of corresponding teaching strategies to enhance the effectiveness of junior high school chemistry experiment teaching.
