Digital electronic technology is a subject of close combination of theory and practice, abstract difficult to understand the theoretical knowledge so that students have a headache, if you can use the experiment, the effect is very different. It can not only help students to understand theory and test theory, but also to cultivate students ' design ability and practical ability of experiment. To understand the experimental techniques, we should grasp the experimental methods, that is, to use the method of experimental testing theory, to seek the methods of the relationship between the physical quantities , to seek the best method of the scheme, etc., to master these methods than simply It is more important to do several experiments .
How to do the digital electronic technology training course? Many teachers reflect that this kind of training class is not easy on, the effect is often a big gap with expectations. No matter how meticulous the teacher's explanation, how smooth the operation, students in strict accordance with the steps of the experimental manual operation, there will be problems. For example, in the traditional teaching experiment process, students in the circuit wiring welding, often do not dare to power-on debugging, because a little careless will "crackling" burned a bunch of components, and instrumentation, improper operation even endanger personal safety. Even if the normal power-on debugging, but in the actual operation is also possible to meet the components, the circuit board of the repeated disassembly, welding, repeatedly set up the fault, the elimination of these operations will aggravate the related experimental facilities and equipment loss. So for the practical training course, the teacher wants to provide students with the opportunity to practice the operation and worry about the various problems in the experiment, equipment loss and student safety and many other factors, so that teachers do not really let go let students do, for the experimental class, can be said to be teachers in the traditional teaching experimental class is the crux of the headache.
until the school began to introduce virtual reality three-dimensional interactive digital teaching resources, so that digital electronic technology will really Theory and Practice tightly bound together. Take the digital display timer experiment as an example, we can first through three-dimensional animation to let students understand the main chip (such as NE555) Working principle and experimental steps, a wealth of three-dimensional model simulation library, can let students according to the experimental requirements of the various types of components required to self- At the same time, the resource platform can be used to provide virtual instruments to check whether the received components are qualified. After testing the components, students can be on the virtual circuit board based on industry standards to build the circuit, but also can be simulated wiring and welding, after the welding can be carried out after the commissioning, the system can be built by the students intelligent judgment. In the process of the experiment can also be free to set up various types of fault, including line failure, device failure, because all three-dimensional model of the platform, animation, scenes have physical properties, so the results reflect the same as the real experiment.
Virtual reality three-dimensional interactive new teaching method not only ensures that each student can enjoy the condition and opportunity of independent experiment, more crucially, it can allow students to experiment freely, fault-tolerant, not confined to the experiment Task book on the specific experimental content, the wrong operation will also appear wrong results, At the same time do not worry about the loss of materials and valuable instrument damage, in order to achieve the purpose of experimental and knowledge consolidation and energy conservation and environmental protection, the theory and practice organically combined to enhance learning effectiveness.
