The invention discloses an auxiliary teaching device, which includes a support assembly and a rotating assembly, the support assembly includes a glass plate, a swivel, a slide bar, a bottom plate and a support bar, and the two ends of the slide bar are respectively fixedly connected to the glass plate and a rotating ring, the rotating ring is located on the upper surface of the base plate, and one end of the support rod is fixedly connected to the base plate; the object to be projected is placed on the glass plate, and then the user twists the rotating rod, At the same time, under the action of the connecting rod and the bracket, the projection lamp and the projection board are driven to adjust their positions through the rotation of the rotation rod, and the projection lamp, the objects on the glass plate and the projection board are always on the same straight line, Under the irradiation of the light, the projection of the object can always be located on the projection board, and then adjusted according to different positions, the user can see the projection of the object at different angles, and then under the rotation of the rotating rod, the manual ability of the students is increased. And enable students to better understand projection knowledge.
Description
technical field [0001] The invention belongs to the technical field of teaching, and in particular relates to an auxiliary teaching device. Background technique [0002] Projection, a mathematical term, refers to the method of projecting a figure through the shadow of an object onto a surface or a line, making the projection line pass through a point or other object, projecting to the selected projection surface, and obtaining graphics on the surface is called projection method . [0003] In junior high school mathematics teaching, it is necessary to explain the relationship between projected views to students. Simply using textbooks cannot help students understand the knowledge points, especially when junior high school students first come into contact with projected views, their comprehension ability is even more limited, resulting in students being unable to effectively understand the projected views. Project knowledge for learning Contents of the invention [0004] T...
