“自主化学习”教学模式,是以教师的启发导学为基础,以学生的主动探究为主线,以互动式训练为手段,以提高学生元学习为目标的教学方法。这种教法运用启发、自学、讨论、互动、反馈、调控等机制,能激发学生学习的内部动机,充分调动学生学习的主动性和积极性。为了突出以人为本的学生主体观和优质高效的教学效能观,我们采用“自主化学习”进行中学化学课堂教学结构的改革,初步形成了情境质疑→提纲导 The “self-directed learning” teaching model is based on the teacher’s enlightenment and guidance, based on students’ active inquiry as the means, and interactive training as a means to improve students’ meta-learning as the teaching method. This teaching method uses mechanisms such as enlightenment, self-study, discussion, interaction, feedback, and regulation to stimulate students’ internal motivation for learning and to fully mobilize their initiative and enthusiasm for learning. In order to highlight the people-centered concept of student body and the concept of high-quality and effective teaching efficiency, we adopted “self-directed learning” to reform the teaching structure of middle school chemistry classes, and initially formed a situational challenge.
