传统的化学课堂教学没有明确地意识到学生是学习的主体,没有提出如何使学生主动地参与到学习活动中去的办法。而“学案导学”正是以学生自学、自研、互研,学生间合作探究,教师导学释疑为手段进行的教学活动,学生亲身参与课堂教学,真正确立起学生的主体地位。 Traditional chemistry classroom teaching does not explicitly recognize that students are the main body of study, and there is no suggestion on how to make students actively participate in learning activities. The “case study guide” is a teaching activity that takes students self-study, self-study, mutual research, inter-student cooperation exploration and teachers ’guidance and explanation as means. Students participate in classroom teaching by themselves and really establish students’ dominant position.
