学生在优质问题串的驱动下,自行探讨,自主学习.在这样的学习方式中,学生就能真正感受到自己是学习的主人,更能体现学生的主体性,使学生不再是被动的接受者,由此激发其主动参与的热情,激发学生学习的兴趣,给课堂注入活力.这正是我们新课程所倡导的自主学习的一种方式. Under the drive of high-quality question strings, students explore and learn independently. In this way of learning, students can truly feel that they are the masters of learning, and can better reflect the subjectivity of students, so that students are no longer passively accepted. This stimulates the enthusiasm for active participation, stimulates students’ interest in learning, and invigorates the classroom. This is exactly the kind of self-directed learning that our new curriculum advocates.
