Electronic circuit capacity of the student to professional

Abstract With the deepening and development of vocational education, work opportunities needed to become more and more high-ability students and educators to exercise, then how do we achieve it? In this paper, a brief analysis of electronic circuits and professional students the ability to do so.
Electronic circuits are electrical grounds vocational training courses, teaching theory and practical disciplines, teachers have to deal with the relationship between teaching theory and practice of teaching. If teachers use the teaching methods of the past - to explain to teachers and students listening passively, interest will begin to learn a lot of students who are tired of escape, and even the teacher, the students will actively participate in the learning process will be possible to Xueshengxuewan worse, solving practical problems still do not know where to begin.
So, how can we change this problem? Learning, teaching methods can be used to project the needs of the students the ability to enhance the social and Methods.
First, the objectives, the Trust
Should contribute to the professional teachers in the educational process insurance (http://www.gafreepapers.com/). Not only the first-generation of specialized courses teaching courses, specialized perspectives, development, currently in production applications, and the beginning of the study, and enable students to recognize the importance of expertise, to learn professional and technical, then I understand that the professional training material. To study the process of electronic circuits to encourage students to participate in the ability of certification of skills, combined with the properties of the course of social practice activities, such as repair of electronic products to the public, to organize a variety of simulation practice, practice, students master the technology, in turn, inspire them to information theory, the better.
The practice of teaching content, improve the practical ability of students to analyze "blackboard and chalk, training of qualified personnel." The most important aspect of vocational education is the fundamental advantage that students who have a wealth of practical experience, excellent operating ability. Based on the learning theory, may not be suitable for students with high-level professional employment.
The reform of electronic circuits, convergence and cooperation in teaching and learning theory to practice, practice, teaching reform and innovation in content, the practical ability of students to analyze and solve important problems.
(A), strengthen the construction of the laboratory for teachers
Laboratory School: An experimental study of managers in charge of the experimental equipment is ready to work with the students to try and direct the training of teachers and true. By an average of 14 lessons a week to complete the task of not only teaching, but also tedious work of classroom teachers (paper http://www.gafreepapers.com/). There is a limited amount of time and personal effort to ensure that I have the remedial course material is difficult to experiment with.
In addition, the number of people in each class, generally 30 people up and down a lot of work in each experiment and experimental components are sensitive to environmental factors such as humidity, temperature effects cause more debugging problems, it is difficult to get a comprehensive experimental results, often I would not class struggle experimental debugging problems for students to solve, and includes an experimental evaluation.
Reply to this phenomenon through the proper management of laboratory experiments in materials, design, teaching practice in the management of the laboratory task of improving the level of business and technical management of the laboratory, but in the first row of the instructor, Teng more time and effort devoted to teaching, improve teaching efficiency.
(B) For the purpose of experimental subjects, the experimental resolution effects in the spirit of "experimental contact theory, experiment consolidation theory", despite the fact that the experiment is closely related to the theory of teaching materials, consider the factual basis for the student, the author's teaching practice, from shallow-depth, step-by-step, to carry out various experiment. Preliminary experiments oscilloscope is used as a "one-tube amplifier experiment" to carry out the first experiment, the first creation, the experiment runs smoothly. Pupils independent experiments, identify problems, and the ability to problem solve, and develop educational materials for school children on the basis of a detailed experimental briefly explain all the experimental class of experimental precautions, and students for successful independent experiments.Links Download Free Paper http://www.gafreepapers.com Center
Third, the practical problems of teaching automotive electronic circuits () Current problems in the educational process in the classrooms of teachers based on their own experience, as well as the problems of students in the process of testing the reality of the daily life of the electronic circuit of the car's problems summed up their thinking and discussion by the students. Automotive electronic circuits may exist in real life, they share the following characteristics: component breakdown. Breakdown, including the breakdown voltage or over-current and thermal breakdown due to overheating. Performance Breakdown sometimes short-circuit, disconnect sometimes. Because the circuit faults caused by accident, overvoltage overcurrent back often. Aging component or performance degradation. It includes many features such as the ability to reduce the capacitor, causing the insulation resistance, leakage transistors increases, resistance to change, which could forever alter the resistance of the adjustable resistor, relay contact ablation. Components, such as filtering, often due to outdated insulation, coil is blown, formed out of a short-circuiting contacts jitter, one can not even change the initial failure to act. Fault line g. Failure to include loose wiring, bad contact, moisture and corrosion due to poor insulation, short circuit and bypass. Such failures are generally nothing to do with the components.
The problems raised by the students' knowledge of electronic circuits, systems thinking about how to solve the problem? (B) will be led by a teacher who is teaching the practical problems to solve real-world problems can be discussed among the first students in the learning process, every team must learn to explore their knowledge of the fault line of automotive electronics solutions proposed by teachers might increase students lost.
We can restore the science and the need to focus on the details above.
Analysis of the circuit schematic, I see the entire circuit and contacts. When the contacts are not familiar with the models and lines often makes itself, analyzing the circuit schematic, even if the inclusion of surveying and mapping scheme is required. B. Out after the first one, and finally, to determine the state of the technology. Many electronic circuits in the car, performance and technology, in order to protect a variety of reasons, often have removable packs, such as the kind of thick film regulator, the ignition circuit solid ring. The appropriateness of an alternative element g.Such as the number of vehicles imported electronic circuit, can be removed, but sometimes it is not changing the kind of discrete components, often means it should be at home or finding other imported components. This refers to the possibility of component replacement. It is forbidden to use the "test of fire to the fault and why. Traditional methods used for repair of automotive electrical fault often to check on a known fault location and why. Despite the fact that this method is not very safe, reliable and battery damage, but it is still possible with traditional repair methods . imported vehicles equipped with electronic circuit and is not allowed to use this method. poster to avoid current overload. allowed to use the ohm ohm meter multimeter file Rx100 low power transistor for detecting small resistance, so it does not go too much damage.
F. Be careful of electrostatic breakdown transistor. To be demolished demolition medal final; replacement transistor base access.
Tube metal oxide semiconductor have to be careful with electrostatic collapse. Metal arc welding, soldering, disconnect the power plug. Prevent Scorch components soldering iron. To remove and install components, cut out. If so, a couple of solder joints in some directions more than 10 mm, no Scorch components soldering iron, you should use a thermostat or a power of less than 75W soldering iron.
I believe that teaching work is done in such a way that the accumulation of knowledge students should be more useful at the same time, the efficiency and effectiveness of classroom teaching and experiential learning, improve synchronization.
Abstract
