Description

Technical Field

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

[0002] In recent years, with the rapid development of information technology, educational technology has also ushered in unprecedented changes. Especially in the field of English teaching, the application of multimedia technology and network technology has greatly enriched teaching methods and improved teaching efficiency. The traditional English teaching method mainly relies on paper teaching materials, blackboards, chalk and other tools. Although this method is classic, it has obvious shortcomings in stimulating students' interest, enhancing interactivity and practicality. With the popularization of smart devices, more and more teaching devices have begun to integrate multiple functions, such as video playback, voice recognition, touch operation, etc., to meet the needs of modern teaching. However, existing multimodal teaching devices often focus on strengthening a specific function, while ignoring the importance of teacher-student interaction in the teaching process, especially in the aspects of oral training and writing practice. Support is not sufficient.

[0003] In the prior art, although some teaching devices have certain multimedia display capabilities, most of them fail to effectively integrate functions such as writing, recording, and video recording, which causes teachers to frequently switch between different devices during actual use, which not only increases the workload of teaching preparation, but also may affect the continuity of the class and the students' concentration. In addition, for English learning, good pronunciation demonstration and timely feedback are the key to improving students' language skills. However, most teaching devices on the market currently either lack high-quality audio input and output systems, or are not equipped with special software to support real-time language evaluation and feedback, which to a certain extent limits the improvement of teaching effectiveness. Therefore, we propose a multimodal teaching device for English teaching. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a multimodal teaching device for teaching English. By having a display screen, a writing area, a speaker and a microphone, writing, display, voice and audio are combined for teaching to achieve multimodal teaching. The device also has a transparent writing area and a camera for intelligently recognizing written text.

[0038] Working principle: The multimodal English teaching device of the present invention realizes its functions through the following main steps: Start the device: First, the user pushes the device to the predetermined position in the classroom and positions it by the wheel locking mechanism on the base 8. Connect the terminal 11 on the battery 12 to the power source to start the device. At this time, the display screen 2, the speaker 13 and the microphone are all in standby mode, ready to receive instructions.

[0039] Display teaching content: The teacher selects teaching content through the remote control or other control devices, and the display screen 2 will display the corresponding courseware, video or text. The display screen 2 adopts high resolution and high brightness design to ensure that the teaching content can be clearly displayed under various lighting conditions.
