Description

Technical Field

[0001] The present invention relates to the technical field of teaching equipment, and in particular to an online teaching auxiliary device for teachers' oral teaching. Background Art

[0002] Teachers' oral language is a professional skill course that aims to train and consolidate students' Mandarin listening and speaking skills, and improve and cultivate teachers' professional oral expression skills. The course is highly applied, practical and demonstrative. The course content includes three parts: basic Mandarin training, comprehensive oral expression training and professional oral language training for teachers. Through the study and training of Mandarin phonetic knowledge, expression skills, and oral language for teaching and education, students can master the basic theories and pronunciation essentials of Mandarin phonetics and have a certain dialect dialectical ability; have strong reading, speech and speaking skills, and express oral language clearly, accurately and appropriately; master the oral characteristics of teaching and education, and strive to be scientific, concise, vivid and inspiring. Cultivate students to correctly grasp the characteristics of teachers' oral language, use teaching oral language skills, and master the laws of educational oral language, so that they can become users of standardized, civilized and beautiful language.

[0003] Interactivity is a key factor in increasing students' interest and participation. Teaching without interactivity may lead to students' lack of participation, which in turn affects learning outcomes. Oral learning involves a variety of skills, such as customer service, event management, crisis management, etc. The lack of multi-scenario drills means that students cannot practice these skills in a safe simulated environment, which affects the development of their comprehensive abilities. The oral learning major requires a close integration of theoretical knowledge with practice. If the teaching equipment cannot provide actual scenario simulations, students will encounter difficulties in applying theory to practice. The lack of multi-scenario drills means that students cannot be fully prepared to deal with the various challenges in actual work. Summary of the invention

After the subject selection unit is selected, the starting unit activates the projection transmission element to turn on the external projection device connected by wireless signals, and then uses the data transmission unit to transmit the data of the subject teaching materials, and can also use the voice input unit for voice transmission; after the processor component is turned on by the starting unit, the teaching data unit receives the scene subject teaching material information from the data transmission unit, the keywords are compared and extracted through the oral management database, the data matching unit confirms the input keyword features, and the voice receiving unit After receiving the voice keywords from the voice input unit, the voice recognition unit recognizes the voice, and the feature extraction unit extracts features from the voice by comparing it with the voice integration database.

In this unit, students can simulate shopping in supermarkets or markets, practice asking for prices, paying, simulating chatting, introducing friends, and discussing hobbies, etc.Enhance students' social skills, simulate birthday parties, holiday celebrations and other occasions, practice greetings and polite expressions, and finally determine the scene of the subject by the simulation scene confirmation unit and transmit it to the teaching material matching unit; after the teaching processing module completes the teaching material confirmation, the feedback processing component is turned on, the instruction reading unit reads the teaching material instruction of the teaching material output unit, and guides it to the external projection device through the projection transmission element for corresponding projection, the mode reading unit reads the corresponding display teaching mode, and the display mode conversion unit starts the operating motor or the projection transmission element to convert the two display modes to each other, the operating motor drives the linkage bevel gear fixed to its output end to rotate, and when the driven shaft rotates, the bevel gear installed inside the curved frame rotates, and the bevel gear rotates. At the same time, it drives the linked bevel gear meshing with it to rotate, and the bevel gear 2 meshing at the other side of the linked bevel gear also rotates accordingly. Because of the coaxial relationship with the bevel gear, bevel gear 2 and bevel gear 1 will rotate simultaneously in opposite directions, and bevel gear 2 also drives the active shaft to rotate inside the filling tank, and the active shaft and the driven shaft respectively drive the scissor boom 1 and the scissor boom 2 to rotate simultaneously in opposite directions, so that the scissor boom 1 and the scissor boom 2 included in the scissor support mechanism 1 begin to unfold or fold along the fixed plate. When unfolded, it is a display mode. The outer ring belt rollers set at the end points of the scissor boom 1 and the scissor boom 2 will form a rectangular distribution, and the exhibition belt 1 set between the outer ring belt rollers will open in the form of an equilateral rectangle. The teaching promotional cards can be plugged in and out through the T-shaped rail arranged on the outer surface of the exhibition belt, so that it can be displayed from four perspectives. When the scissor-type boom 1 and the scissor-type boom 2 are unfolded, the linkage column opened at the bottom thereof will drive the linkage rod 1 and the linkage rod 2 included in the scissor-type linkage mechanism and the scissor-type support rod 1 and the scissor-type support rod 2 included in the scissor-type support mechanism 2 to unfold, so that the scissor-type linkage mechanism and the scissor-support mechanism 2 are synchronized with the operation of the scissor-support mechanism 1, and the scissor-type unfolding mechanism is also synchronized. The scissor-type unfolding rod 1 and the scissor-type unfolding rod 2 included in the scissor-type unfolding mechanism rotate with each other to form a scissor-type structure, one end of the scissor-type unfolding rod 1 and the scissor-type unfolding rod 2 are connected to the scissor boom 1 and the scissor boom 2, and the other end is connected to the linkage rod 1 and the linkage rod 2 respectively. When the scissor-type booms 1 and 2 are unfolded, the scissor-type booms 1 and 2 will cross each other and fold, and pull the linkage rods 1 and 2 upward, so that the sliding rollers installed at both ends of the linkage rods 1 and 2 begin to slide upward synchronously along the linkage column until the sliding rollers are wrapped into the interior of the exhibition belt 1, forming only four display surfaces composed of the exhibition belt 1. When the scissor-type support mechanism 1 is driven by the operating motor to fold, it is another display mode. The scissor-type booms 1 and 2 will move closer to each other and fold, and the exhibition belt 1 will also begin to fold with the outer ring belt roller and change into a rectangular shape. After the scissor-type booms 1 and 2 are folded, the exhibition belt 1 has two display areas with larger relative areas. The scissor-type unfolding mechanism is also under the influence of the folding action of the scissor-type booms 1 and 2.Push the scissor linkage mechanism downward, and the scissor linkage mechanism will fold synchronously with the scissor support mechanism 1, while driving the sliding sleeve roller and the exhibition belt 2 that is connected between the sliding sleeve rollers to descend. The exhibition belt 2 will also form a relatively larger display surface due to the folding of the linkage rod 2 and the linkage rod 1, and will be combined with the exhibition belt 1 to form a larger projection screen mechanism. At this time, the external projection equipment can be started through the projection transmission element to carry out multi-scene oral teaching and voice response teaching.

[0025] The present invention provides an online teaching auxiliary device for teachers to teach oral English.

[0026] Beneficial effects:

[0027] 1. The present invention has enhanced interactivity and practical experience effects. By simulating various oral teaching scenarios, this system provides a learning environment close to reality. Students can understand and apply theoretical knowledge through practical operations, thereby gaining a deeper learning experience. By simulating different scenarios such as customer service, dispute resolution, and sales, students can practice coping with various situations in a safe environment, thereby improving their adaptability and decision-making skills. The system covers multiple aspects of oral teaching, from reception and reservation to dispute resolution, and provides comprehensive educational content to ensure that students can fully understand and master all aspects of oral teaching, visualization, and multi-sensory learning.

[0028] 2. The present invention has visualization and multi-sensory learning effects: through projection and other visual display technologies, the system provides a rich multi-sensory learning environment, which helps to improve the attractiveness of learning and the memory effect. The system supports a variety of teaching modes and scene switching, including voice input and feedback processing, which increases the flexibility and dynamism of the learning process. This diversity helps to adapt to different learning styles and needs. Through intelligent data matching and scene simulation, students can obtain relevant information and feedback more quickly, accelerating the learning process. At the same time, the automation characteristics of the system reduce the administrative burden on teachers, allowing them to focus more on teaching.

[0029] 3. The present invention has a variable multi-angle visual display effect: driven by the operating motor, the structure can switch between different display modes, such as from a compact mode to a fully expanded mode, which provides a variety of display methods suitable for different teaching scenes and contents. Through the design of the exhibition belt and T-shaped rail, the teaching content can be displayed from multiple perspectives, thereby improving the visual appeal and information acceptance.

[0030] 4. The present invention has a dynamic structural adjustment effect: the combination of scissor-type booms, linked bevel gears and sliding rollers allows the system to undergo complex structural changes when expanded and contracted. This dynamic adjustment enables the display structure to adapt to different space requirements and visual display effects. The structure allows students to participate in the teaching process through physical interaction (such as inserting and pulling cards) to enhance the learning experience. Through the design of the scissor-type structure, the system can provide a maximized display area within a limited space, which is particularly useful for teaching environments with limited space.
