Description

Technical Field

[0001] The invention relates to the technical field of teaching, and in particular to a multimodal English teaching device. Background Art

[0002] Multimodal teaching means that in the teaching process, teachers use a variety of teaching methods and resources, such as text, images, sounds, videos, etc., to stimulate students' learning interest and improve teaching effectiveness. In English classes, multimodal teaching is particularly important because learning English as a language is not just about memorizing words and grammar, but more importantly, being able to use language for effective communication.

[0003] In current English teaching, exams are the main way to evaluate students' learning status and level. However, the existing exam feedback mechanism has obvious defects. After the exam, although the students' test papers will be distributed and explained by the teacher as a whole, due to the different distribution of wrong questions in each test paper, some questions have a higher frequency of errors, while some questions have fewer errors. When listening to the lecture, students can only rely on the teacher's explanation to understand their own mistakes, and cannot intuitively see other students' test papers, especially those questions with a higher frequency of errors. This one-way explanation method makes students' understanding of wrong questions not deep enough, especially for those repeated mistakes, students lack sufficient visual and interactive experience to deepen their memory. In addition, the teacher may skip some repeated wrong questions during the explanation, which further weakens the students' impression of these questions. Therefore, the existing teaching method is insufficient in terms of wrong question feedback and interactivity, and cannot effectively help students understand wrong questions comprehensively and deeply.

[0004] To this end, we have developed a new multimodal English teaching device. Summary of the invention

Then the transverse movement component 8 operates to drive the electric deflection bracket 3 and the camera 4 to move. When the camera 4 is separated from the protective component 5, the electric deflection bracket 3 operates to change the position of the camera 4 so that the placement rack 7 is located between the two cameras 4.
