The application discloses a kind of education resource sequence recommendation method, device and equipment based on three-view structure distillation and storage medium, the method includes: based on student-course interaction log, the learning sequence of time sequence course index is constructed, three types of view hypergraph are constructed according to semantic, path, concept structure multidimensional feature, three-view course representation matrix is generated by structure coding fusion, and the recommended list is output by inputting education resource recommendation model;Education resource recommendation model generates student state vector by the coding of Transformer, and the total course score is obtained by fusing three-view branch score and predicted;The present application predicts the education resource recommendation by three-view collaborative scoring from multiple perspectives, accurately captures course representation, effectively depicts learning path high-order law, improves the accuracy, explainability and generalization ability of education resource recommendation in sparse interaction and cold start scene.

The utility model discloses a kind of multi-angle rotating projection devices, it is related to projector technical field, including projector, further include: clamping component, for the projection device is fixed on support surface;Lifting assembly, it is set on the clamping component, for driving the projector to carry out lifting movement;Rotary component, it is set on the lifting assembly, for driving the projector to carry out horizontal direction rotation.The utility model is through setting clamping component, through rotating handle operating screw rod, laborsaving and accurate.Using person can be intuitively controlled the tightness degree of clamping by rotating number, avoid damaging equipment due to excessive force, simultaneously chuck can be rotatably arranged at the end of screw rod, prevent rotating friction piano surface, cause scratch to appear on the surface of piano cover, and by cooperation between L-shaped rod and spring, chuck two sides can be abutted to the side of piano cover, avoid chuck autorotation.

This utility model relates to the field of teaching aids technology and discloses a sound teaching aid, including a main board and an amplitude adjustment plate. An adjustment mechanism is fixedly installed at the center of the upper surface of the main board. Slots are formed at the front and rear ends and near the edges on both sides of the upper surface of the main board. A locking block is fixedly installed at the lower end and one side of the amplitude adjustment plate. The adjustment mechanism includes an adjustment box and a positioning block. Positioning grooves are formed on the upper surface, front and rear ends, and both sides of the adjustment box. Circular magnets are embedded in each of the five positioning grooves. A square magnet is embedded in the lower end of the positioning block. A steel ruler is fixedly installed on the upper end of the positioning block by bolts. In this utility model, the magnetically fixed adjustment mechanism facilitates adjustment of the spatial orientation of the steel ruler, enabling adjustment from vertical to horizontal placement. Combined with the synchronously adjustable amplitude adjustment plate, it helps users observe the changes in the vibration amplitude of the steel ruler at different horizontal angles, thus better understanding the vibration propagation of sound in different directions.

The invention discloses a domain knowledge driven intelligent teaching assisting system based on multi-agent cooperative workflow, and relates to the technical field of education, and the system is characterized in that a workflow scheduling agent creates a task context, transmits information and dynamically arranges an agent combination; the resource perception collects textbooks and the like and outputs standardized data; constructing a knowledge graph on the basis of knowledge construction; questions are understood and answered to generate answered student questions; planning a learning path according to the learning strategy; the interaction and feedback realize input and output conversion, content presentation, collection and feedback to the scheduling agent; a multi-agent collaborative architecture is adopted, teaching materials are integrated to construct a knowledge graph, students' questions are accurately understood, answers fitting key points are generated, personalized learning paths are planned, multiple interaction forms are supported, a complete closed loop is formed, the mode adapts to different students, knowledge weak points are made up, traditional limitations are broken through, initiative is stimulated, and the learning efficiency is improved. And collaborative improvement of learning efficiency and teaching quality is realized.
