Cognitive diagnosis tool for solving teaching problem

Abstract

The invention aims to solve teaching problems, and discloses a cognitive diagnostic tool for solving a teaching problem. The cognitive diagnostic tool comprises a mounting plate. A first motor is mounted in the middle of the surface of the mounting plate; a rack is fixedly connected between the first motor and the mounting plate; a first rotating shaft is mounted on the left side of the first motor; the left side of the surface of the first rotating shaft is fixedly sleeved with a rotating disc; a protruding block is fixedly installed on the periphery of the rotating disc; a wheel frame is fixedly connected to the outer side of the protruding block; a guide wheel is sleeved with the wheel frame; connecting plates are symmetrically installed on the two sides of the surface of the mounting plate; first fastening screws are symmetrically installed between the connecting plates and the mounting plate; connecting frames are connected to the left sides of the connecting plates; a spiral spring is fixedly mounted between the corresponding connecting frame and the mounting plate; and hydraulic cylinders are sleeved with the connecting frames. According to the cognitive diagnosis tool for solving the teaching problem, the blackboard-writing content on a blackboard is marked through a connecting belt, so that the blackboard-writing content is stored, students can learn repeatedly, and the teaching efficiency is improved.

Description

technical field [0001] The invention relates to the field of teaching, in particular to a cognitive diagnosis tool for solving teaching problems. Background technique [0002] Cognitive diagnostic test is an improvement and perfection of traditional examination and evaluation. Educational tests in general, especially large-scale ones, only provide test scores or competency scores. However, from a single score, neither the conclusion of what knowledge the subject has or has not mastered, nor the reasons for the subject's wrong test questions can be obtained for remediation; differences in knowledge status and cognitive structure. The information provided by traditional examinations is no longer suitable for the needs of individual development. The main task of cognitive diagnostic assessment is to mine more cognitive processing information according to individual differences. [0003] When teaching, the teacher writes on the blackboard. Generally, it will be erased after w...

Problems solved by technology

[0003] When teaching, the teacher writes on the blackboard. Generally, it will be erased after writing, and the written on the blackboard will not be able to be viewed again, which will easily affect the students' learning of the teaching content. In the process of teaching, the blackboard written by the teacher is not easy to save, and it is inconvenient in the follow-up teaching. Therefore, it is urgent to design a cognitive diagnostic tool to solve teaching problems.
