Teaching Design and Reflection on the Scientific Experiment of Making Drone Remote ControlThe following is a teaching design for a scientific experiment to make a drone remote control:
** 1. Teaching objectives **
1. ** Knowledge and Skill Target **
- Students can understand the basic working principle of the drone remote control, including the signal transmission, transmission, and conversion mechanism.
- Master the functions of each channel of the remote control (such as aileron, lift, throttle, direction channel, etc.) and the corresponding relationship with the flight movements of the drone.
- Learn how to make a simple drone remote control or understand the key links in the production process.
2. ** Course, Method, and Target **
- Through theoretical explanation and practical operation (if possible), students 'practical ability and logical thinking ability will be cultivated.
- To let students experience the process from design to production (or understanding production), and improve their ability to solve practical problems.
3. ** Emotions, attitudes, values, goals **
- Stimulate students 'interest in drone technology and cultivate their love for technological innovation.
- Cultivate the students 'teamwork spirit and improve their patience and perseverance in the face of technical challenges.
** 2. Important and Difficult Points in Teaching **
1. ** Teaching Focus **
- The working principle and basic functions of the drone remote control.
- The key technical points in the process of making the drone remote control, such as the construction of the signal transmission module, the setting of the control channel, and so on.
2. ** Teaching Difficulties **
- How to transform complex electronic circuit knowledge and flight control principles into simple and understandable content to teach students.
- To ensure the safety of students during the production process (if actual production is involved), especially when dealing with electronic components and radio equipment.
** 3. Teaching Method **
1. Teaching method: Explain the basic principles, structure, and functions of the drone remote control.
2. Demonstrating method: Demonstrate the working process and production process of the drone remote control through pictures, videos, or physical objects (if possible).
3. Group Cooperation Method: If it is a practical production project, the students can be divided into groups and let them work together to complete the production of the remote control to cultivate teamwork.
** 4. Teaching process **
#(1) import (5 - 10 minutes)
1. By playing a wonderful drone flight performance video, it aroused the students 'interest.
2. Ask the students,"Do you know how the drone flies according to our ideas?" He guided the students to think about the role of the remote control, which led to the theme of this lesson-the production of the drone remote control.
#(2) Explanation of theoretical knowledge (20 - 30 minutes)
1. How the remote works
- Explain how the drone remote control communicated with the receiver on the drone through radio waves. When the remote control's control lever was operated, these actions were converted into radio wave signals and sent to the drone receiver. The receiver then interpreted the signals and converted them into digital signals for transmission to the drone control system, thereby controlling the drone's flight.
2. Remote Control Core Channel and Function
- Explain in detail each core channel, such as the flap channel.(responsible for controlling the drone to roll around the vertical axis, and operate it left and right through the right rudder of the remote control), elevator channel (responsible for the pitch action, and control the drone to move forward and backward through the front and back operation of the right rudder), throttle channel (control the drone to rise or fall along the vertical axis, and adjust the motor speed through the front and back operation of the left rudder), direction channel (control the direction of the drone, which is reflected in changing the direction of the body rotation in the multi-roter drone, and changing the direction of the nose by operating the vertical tail).
3. Principles of Production (if it is a production course)
- It briefly introduced the functions and relationships of the electronic components involved in the production of the drone remote control, such as the launch module, control chip, signal processing unit, etc.
#(3) Practice (20 - 30 minutes if possible)
1. The students were divided into groups, and each group was assigned a set of production tools and materials (or materials for simulation production).
2. According to the pre-designed production process, guide the students to make the remote control step by step.
- For example, first install the signal transmission module, then connect the control channel circuit, and finally carry out the overall adjustment.
3. During the production process, he would patrol the teams and answer the students 'questions in time to ensure the smooth progress of the production process.
#(4) Summing up and Evaluation (10 - 15 minutes)
1. Ask the representatives of each group to show the remote controls they made (or the results of their production, if it was a simulation), and briefly introduce the production process, problems encountered, and solutions.
2. They evaluated the students 'performance, including their mastery of theoretical knowledge, practical ability, teamwork, and so on.
3. To summarize the key content of this lesson, he once again emphasized the working principle, functions, and production points of the drone remote control.
** 5. Reflection on Teaching **
1. ** Success **
- The video could effectively attract the students 'attention and stimulate their interest in learning.
- In the process of explaining theoretical knowledge, the function of the remote control channel was explained in combination with actual flight movements, which helped the students better understand the abstract knowledge.
- If there was a practical operation segment, the group cooperation method could cultivate the students 'teamwork and hands-on ability. At the same time, during the production process, the students' understanding of knowledge would be further deepened.
2. ** Inadequacies **
- For some students with poor foundations, they might have difficulty understanding the theoretical knowledge. They needed to use more examples or simpler explanations in the subsequent teaching.
- If it was a production course, some teams might not be able to complete the production tasks due to limited time in the practical operation segment. They needed to arrange their time more reasonably or simplify the production process.
- In the evaluation process, more attention was paid to the students 'results. The students' thinking process and innovation points in the production process were not explored enough. They needed to be considered more comprehensively in future evaluations.
