First, the specific methods of implementing the integration of theory and practice teaching model

(A clear teaching objectives

The main content of this course is to learn the working principle of AC and DC circuits composed of resistors, capacitors and inductors. The main goal of this course is to enable students to analyze and solve common AC and DC circuits on the basis of mastering these components and combining the theoretical knowledge they have learned, and to apply what they have learned to practical operation to guide practice, so as to meet the needs of employers and the trend of social development. Based on the above factors, the teaching process of electrical technology course is roughly divided into the following modules. Module 1: Basic concepts in circuits. Including the composition of the circuit, physical quantities in the circuit, resistance, ohm's law, electric work and electric power. These knowledge can be learned by operating ammeter, voltmeter, multimeter, regulated power supply, insulation resistance meter and other experiments, and the combination of theoretical knowledge and practical operation can be realized. Module 2: DC circuit analysis. Including series and parallel connection of resistors, voltage source and current source, Kirchhoff's law and branch current method, capacitance and inductance. This knowledge is learned through series-parallel resistance experiment, Kirchhoff's law experiment and capacitor charging and discharging experiment. Module 3: Single-phase sine and three-phase AC circuits. Including the generation of sinusoidal alternating current, basic physical quantities, RLC series circuit, the generation of three-phase alternating current, the connection of three-phase power supply and the safe use of electricity. Alternating current is the most common in real life, and three-phase electricity is widely used in power supply. This part of the content is learned through the understanding of sinusoidal AC circuit, the measurement of AC series circuit, the star connection of three-phase load and the installation of lighting circuit.

(B) Teaching implementation process

In the process of realizing the basic concepts in module-circuit, it is necessary to explain and introduce the related knowledge in detail by using blackboard writing and multimedia. After that, students will be given a lot of time to operate ammeter, voltmeter, regulated power supply, insulation resistance meter and other instruments independently to deepen their understanding of theoretical knowledge. During this period, through the use and operation of multimeter, master the zero adjustment method and matters needing attention of multimeter. In addition, the measurement and reading methods of current, voltage and resistance can be mastered through practical operation. In the DC circuit analysis of module 2, the electronic devices such as resistance, capacitance and inductance are explained in detail. These components are important components of DC circuits and AC circuits, and it is very practical to operate and establish DC circuits through them. In addition, this module also has an important law of DC circuit-Kirchhoff's law, which is instructive to analyze the working principle of DC circuit. The third module is single-phase sine and three-phase AC circuit. Students need to master the star angle connection of AC circuit, RLC series circuit, three-phase AC and three-phase load through learning. In the installation experiment of fluorescent lamp circuit and lighting circuit, students not only learned the theoretical knowledge of AC circuit analysis, but also mastered the actual operation in the actual circuit installation process.

(3) Problems and solutions in the implementation process.

Distribution of course hours: In the past, most of the teaching arrangements were 2 hours each time, so that after the teacher taught the theoretical knowledge, students did not have enough time to absorb the theoretical knowledge in class, let alone apply the theoretical knowledge to practice. And the theoretical content mentioned before the next class has been forgotten a lot. Based on this, the class hours were adjusted and the course of integration of theory and practice was changed to 4 hours. The advantage of this is that when students are listening to the theoretical knowledge told by the teacher, when I haven't forgotten it, let students strengthen the digestion of theoretical knowledge through practical operation, which will help them understand the knowledge on the one hand and improve their practical operation ability on the other. Place of implementation: The traditional teaching mode is usually classroom teaching, which focuses on the study of theoretical knowledge and does not have the conditions for practical operation. The implementation place of the integration of theory and practice teaching is the training room or laboratory, which not only has the conditions for theoretical knowledge teaching, but also can use training equipment and instruments for practical operation. In this way, teachers can teach theoretical knowledge while demonstrating practice on the spot, and the teaching effect is better. Transformation of teaching mode: In the traditional teaching mode, teachers play a leading role in teaching, and students usually play the role of cooperating with teachers. In this case, students' learning enthusiasm is not too high, and their learning initiative has not been fully mobilized. The integrated teaching mode of theory and practice makes students become the main body of teaching, and the teacher's duty is more to guide students, which can greatly arouse their enthusiasm and initiative in learning.

Second, the benefits of the integration of theory and practice teaching model

(A) to help students have a deeper understanding of theoretical knowledge.

In the process of implementation, the knowledge of resistance, capacitance, inductance, common circuits and instruments can be obtained through the training room, instead of relying on teachers' explanations, students' imagination or multimedia means in traditional teaching. In this way, the original imaginary knowledge content has become a vivid thing in reality, allowing students to learn more about this knowledge.

(B) help to improve students' practical ability.

In the teaching process, the operating platform of the training room or laboratory is provided, so that students can give full play to their subjective initiative and carry out practical operations instead of rote learning in the traditional teaching mode, so that students can have more practical opportunities in learning theoretical knowledge and have a deeper understanding of the guidance of theoretical knowledge in the practice process.

(C) help to improve students' interest in learning

In the process of implementation, students are no longer the supporting role of teachers' teaching, but the dominant position, which will inevitably stimulate students' interest in learning, and students will participate in the teaching process more actively, and complete the theoretical knowledge and practical operation teaching with teachers efficiently.

Three. Concluding remarks

The integrated teaching mode of theory and practice of electrical technology combines theoretical knowledge teaching with practical operation well, and spans the gap between practice and theory. It successfully integrates the theoretical knowledge, hands-on practice and social needs of the electrical technology course. Teaching hours are more concentrated, teaching places are changed from classrooms to training rooms, and teaching methods are changed from teachers to students. Through these changes, the distance between teachers and students can be narrowed, and students can operate in theory and verify the theory in operation. A two-pronged approach will enable them to understand and master theoretical knowledge more deeply and vividly, and at the same time improve their practical operation ability, and gradually make themselves high-quality and practical talents that meet the needs of employers and society.
