METHODS: A 3D electric ophthalmotrope was designed by simulating the movement of the ocular and the extraocular muscles according to Sherrington’s law. The model with joint bearing was to ensure the flexibility and centripetal rotation of the simulated ball and stepper motor as the driving device. A programmable processor was used to control the motion amplitude of the stepper motor. The size of hole was set at the back of the simulated shell to limit the amount of eye movement. Afterwards, using a 5-point Likert scale, 7 experts evaluated the 3D electric ophthalmotrope’s simulation ability and precision, compared with the traditional anatomical model. In addition, the teaching effectiveness of the 3D electric ophthalmotrope was evaluated at in-class quiz and final exam in a randomized controlled trial. RESULTS: The 3D electric ophthalmotrope could be operated easily to demonstrate the eye movements with motion of different ocular muscles. The experts agreed that the 3D electric ophthalmotrope was different from the traditional model and was easier for students to understand every extraocular muscles’ movement in each evaluation index(P<0.05). Moreover, the results of teaching effectiveness showed that the 3D electric ophthalmotrope were significantly greater than the traditional model both at in-class quiz(P<0.01) and final exam(P<0.05). CONCLUSION: This novel 3D electric ophthalmotrope is better than the traditional model, which can be to improve the ophthalmology teaching effectiveness for students to understand the extraocular muscles’ movement.展开更多

The axisymmetric and central symmetry of the function itself and the axisymmetric and central symmetry between the two functions are explored respectively. On the basis of studying the problem of function symmetry, the universal applicability of the above three tools in high school mathematics teaching is further discussed and prospected. In high school, the symmetry, as one of the basic properties of functions, is not only the content that teachers should focus on in teaching, but also a key knowledge module that it is difficult for most students to understand deeply. Its importance need not be repeated.展开更多
