Production Of Magnetic Teaching Aids And Its Application In High School Biology Teaching

Self-made teaching aids refer to the teachers or students making teaching aids by themselves according to their conceptual design of teaching content. There are a lot of materials and production process on self-made teaching aids:Based on the compulsory modules contents of PEP biology for high schools, which using magnetic rubber sheet (disk) as the main material and other auxiliary materials. Follow the basic principles of self-made teaching aids design, the teachers have designed the 17 sets of disk aids by teaching design (function), design (structure) choosing materials, processing trial, modification and other basic steps.In the practical application of self-made teaching aids, the teacher selected the five parts of teaching contents as a case from the teaching material to carry out teaching activities, and the questionnaire survey was conducted to evaluate teaching effect after the course.The results show that:1. The students like the self-magnetic teaching aids’ intuitive image, combination of simulation, bright and beautiful, especially the three-dimensional aids.2. It has a greater influence on the learning ability of students is to deepen understanding of knowledge, the second is associated with more imagination, the last is initiative thinking analysis.3. Students loved the teaching method. Students and teachers operated on aids and it can enhance students’sense of accomplishment.4. Most of the students hope to make their own disk and they want to search for knowledge by the self-made magnetic teaching aids in a group.5. The liberal arts students’acceptance, operation, and speculation on the self-made magnetic aids is more difficult than science students.Through the study, the teacher summed up a set of self-made disk and its application of the basic methods and steps:simulation showing some unknown facts, observation analysis, associating reasoning, simulation display communication and simulation presenting new knowledge.The teacher put forward the teaching suggestions on the application of self-made teaching aids as follows:1. Design and production of self-made teaching aids, teachers and students should participate in together.2. The teachers should consider students’thinking reasoning space and simulation implementation fully during the design and use.3. The teachers should consider regarding students’ performance as the main part in the activity and teachers’demonstration as main introduction when they used it.4. Self-made teaching aids can promote the development of teaching aids.5. It can help to change teaching mode through the use of self-made magnetic aids and teaching aids. 6. Information technology should combine with self-made magnetic teaching aids.
