在分组实验探究中,以学生主动探究为主,教师则是明确实验目标,指导学生设计实验方案,分析、讨论、归纳、综合实验信息,得出实验结论.这有利于培养学生独立思考、自主学习、实践操作的能力.一、明确实验目标在分组实验教学中,教师应引导学生明确实验目标,实验要求与目的,让学生有目标地进行探究.因此,在实验探究之前,教师可创设一定的问题情境,以吸引学生的课堂注意力,调动学生的求知欲,让学生积极融入到实验探究中.当然,实验目标应具有讨论性、针对性、可行性,以培养学生合作精神,提高学生的探究能力.例如,在探究“小车速度随时间变化的规律”时,教师可这样导入新课:一般而言,物体运动是较为复杂的,不同的 In the grouping experiment research, the students take the initiative to explore mainly, the teacher is the clear experiment goal, guides the student to design the experiment plan, analyzes, discusses, induces, synthesizes the experimental information, draws the experimental conclusion.This is advantageous in cultivating the student independent thinking, the autonomy Learning and practical operation.A clear objective of the experiment In the group experiment teaching, teachers should guide the students to clear the experimental objectives, experimental requirements and purposes, so that students have the goal to explore.Therefore, before the experimental exploration, teachers can create a certain Of the problem situation in order to attract students ’attention in the classroom, to mobilize the students’ curiosity, so that students actively involved in the experimental exploration of course, the experimental objectives should be discussed, targeted and feasible to develop student cooperation and enhance students For example, when exploring the “law governing the speed of a car over time,” teachers can import new lessons this way: In general, object motions are more complex and different
