初中化学教学内容既包括理论知识教学,也包括化学实验教学,所以在新课程改革理念下,提高教学有效性就要全面关注教学质量,提高教学效率。教学有效性的提高有助于在实现教学目标的同时关注学生化学知识体系的构建,老师教学方法的丰富,以及对学习方法的指导,从而更加全面地关注教学的各个环节。所以从转变教学观念、高效备课、丰富教学方法、注重实践等几个方面来研究提高初中化学教学有效性的策略。
The content of junior high school chemistry teaching includes not only theoretical knowledge but also chemistry experiment teaching. Therefore, under the new concept of curriculum reform, to improve teaching effectiveness, we must pay attention to teaching quality and improve teaching efficiency. The improvement of teaching effectiveness helps to pay more attention to all aspects of teaching while paying more attention to the construction of students ’chemical knowledge system, the enrichment of teachers’ teaching methods and the guidance of learning methods. Therefore, the strategies to improve the effectiveness of junior high school chemistry teaching are studied from several aspects, such as changing teaching ideas, preparing lessons effectively, enriching teaching methods and focusing on practice.
