Description

Technical Field

[0001] This utility model relates to the field of English teaching technology, specifically to an English teaching vocabulary display device. Background Technology

[0002] In English teaching, common words are listed on the blackboard and explained one by one through their roots and parts of speech. Combinatorial words are also listed on the blackboard, such as words with prefixes and words with suffixes. However, with so many words, writing them down one by one to display and explain them would greatly increase the workload of teachers and would also make it difficult for students to memorize them.

[0003] In the prior art, such as the Chinese utility model application with application number 202121107887.6 entitled "An English Teaching Vocabulary Display Device," a piece of paper with words written on it is fixed to a teaching roller by an elastic component. By rotating the teaching roller, the words fixed on different sides of the roller are displayed. However, this method has the following problems in use:

[0004] 1. Only one teaching roller is set up, and the paper with words written on it is fixed to its side. Only a limited number of words can be displayed, and the roots, prefixes and suffixes that make up the words cannot be displayed separately. New words cannot be formed by combination, which is not convenient for students to understand and remember.

[0005] 2. Simply fixing the paper with the words written on it to the teaching roller using the elastic component is not very effective. The paper is easy to fall off during the rotation of the teaching roller.

[0006] This invention addresses these issues by proposing an English teaching vocabulary display device. The device can display the roots, prefixes, and suffixes that make up words, and can form new words according to word formation rules, which is convenient for students to understand and remember. At the same time, the vocabulary cards have a better fixation effect. Utility Model Content
