近日,听取一位老师执教了《铁生锈》(青岛版六年级上册)。上课后师生观看视频《身边生锈的危害》引入了新课,在师生互动学新课环节,让学生看视频《铁钉生锈的条件》,并在黑板上加以板书。在生活实践与应用环节,又播放视频《钢铁的锈蚀与防护》。在整个学习过程中,教师既没有自己做实验把过程和结果呈现给学生,也没有让学生亲自动手做一做,亲身感受这种变化,只是通过视频,老师将结果告诉学生。
Recently, listening to a teacher coached the “iron rust” (Qingdao version of the sixth grade). After class, teachers and students watched the video “The Risks of Rust Around” and introduced a new lesson. During the new course of teacher-student interaction, students could watch the video “Rusty Conditions of Nails” and put on the blackboard a blackboard. In the life practice and application links, but also play the video “rust and protection of steel.” Throughout the learning process, teachers did not experiment with their own process and the results presented to the students, did not let the students do it one hand, to experience this change, but through the video, the teacher told the students the results.
