Research On Comprehensive Inquiry Teaching Design Of Mechanics In Senior High School

This teaching design integrates high school physics mechanics of the gravity,elasticity,friction,force decomposition with Newton's law of motion and other related knowledge,and takes the common "slide" facilities in life as the background,takes the "how to simulate human slide slides" as the core to carrying out inquiry learning so that students can find problems,think problems and solve problems in real situations.Emphasizing that every student is actively involved in the activities,making the students become the master of the class instead of the passive participant,and cultivate the students' interest and confidence in the physical learning.The author designed this teaching activity after researching the development of "the coins slide from the surface of the book".From the starting question "Is there a minimum height for the slide" to "why the objects on the slope can not slide" and "how to simulate human slide slides" can be carried out to achieve qualitative analysis of the slope problem,and finally achieve quantitative analysis of the slope problem through "calculating the object's slide time" and "application and calculation of the slide".So that students learn to perform comprehensive mechanical analysis of the objects on the slope and have a deeper understanding of the friction.The innovation of this article lies in introducing the real slide situation into the classroom from a new perspective.The selected materials and experimental instruments are all close to life.Students can draw materials conveniently and operate at any time.The entire project uses the "slide" as a carrier,from the simulation of the slide to the understanding of the slide,and finally designing the slide,so that students have a deeper understanding of the comprehensive mechanical problems on the slope,and the students' divergent thinking and scientific creative ability are trained.
