Description

An adjustable whiteboard

technical field

The utility model relates to the technical field of teaching whiteboards, in particular to an adjustable whiteboard.

Background technique

In elementary school English teaching, improving students' interest in learning English is an important teaching goal. Teachers should take the initiative to establish a harmonious relationship between teaching and learning, take students as the main body, give full play to students' learning initiative, and mobilize students' learning enthusiasm. Classroom teaching through listening, speaking, reading, writing, acting and games, etc., allows students to learn in a happy classroom atmosphere, so that students can be confident in English learning, thereby improving the effect of English teaching in primary schools. In actual teaching activities, Teachers should create a good teaching atmosphere and learning environment, so that students can learn English in a relaxed and happy environment. For example, schools can carry out some beautification and decoration in classrooms and other places, and draw some English paintings on the walls of the school or story characters, etc., to create a good English learning atmosphere, so that students can maintain a sense of freshness and strong curiosity about English learning, use English to express some daily expressions in English classes, and continuously improve students' English Oral expression ability, but when the traditional whiteboard is used, the materials are not convenient to fix. Usually, the lecturer needs to repeatedly lift the prepared materials and let the students see. The time that the students can see is relatively limited. There is a sense of soreness, and students have a poor impression of the material, and the traditional whiteboard is usually a whole, which often requires two people to carry it as a whole when moving, and the flexibility is poor.
