以问题引领的任务驱动的方式,是指教师在课堂上把本节课的内容设置为具体的情境问题,以问题驱动促使学生完成教学任务,以此调动学生学习的积极性.使学生在学习过程中发现新问题,并解决问题.这节课创设、模拟各种不同的情境,推导外力对物体做的功的表达式,从而得出动能和动能定理的表达式.从单过程到多过程,从直线到曲线、从恒力到变力,目的是让学生感悟运用动能定理的优越性和适用的广泛性;注重学生参与过程,主动探索、发现和获取知 The problem-driven task-driven approach refers to the teacher in class to set the contents of this lesson as a specific context to problem-driven students to complete the task of teaching, in order to mobilize the enthusiasm of students to enable students in the learning process In this lesson to create, simulate a variety of different situations, derive the expression of external work done on the object, and thus come to the kinetic energy and kinetic energy theorem expression.From the single process to multiple processes, From straight to the curve, from constant force to variable force, the purpose is to enable students to perceive the use of kinetic theorems superiority and the applicability of the extensive; pay attention to the process of student participation, take the initiative to explore, find and access to knowledge
