<p> 疫情当前，为了提升学生能力，激发学生学习热情，增加学生间的交流学习，昊天学校九年级数学备课组筹划了“争做数学小讲师”的学科实践活动。</p><p> 各班同学全部参加，在中考试题中选取一个专题的题目进行讲解，可以利用ppt、几何画板等工具，旨在讲的同学能够讲清楚，听的同学能够听明白。</p> 准备工作 <p> 任务一布置下去，各班同学积极参与，挑选题目，认真制作课件和视频。在挑选题目的过程中，同学们对中考专题有了更深刻的思考和学习；在制作课件的过程中，同学们学会了几何画板和录屏软件的使用方法；在讲解题目的过程中，同学们表达流畅自然，讲解的有理有据！</p> 修改完善 <p> 同学们录制后请老师提出意见，一遍遍进行修改。修改后的作品语言顺畅、讲解条理清晰，并且能熟练使用画图工具。</p> 精彩回顾 <p> 本次活动以小组为单位，各组组长认真负责，组员积极配合，合作学习，加强了同学们的协作沟通能力和团队意识。为了更好的交流展示，各班各组的同学将本组的作品制作成精彩的美篇。欢迎大家点开下面的链接一睹我们九年级小讲师的风采，为你心目中最好的小讲师投票！</p> <p><a
