Teaching Design and Reflection on the Scientific Experiment of Making Drone Remote Control
The 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. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to write the video of scientific experiment making popcorn, teaching reflection
The following is an example of a reflection on the science experiment of making popcorn: ##I. Achievement of Teaching Aims 1. ** Knowledge Comprehension ** - In the science experiment teaching of making popcorn, the aim was to let students understand the principle behind the corn turning into popcorn. For example, the starch and water in the corn expanded when heated, and the shell could not withstand the pressure and burst open. However, during the video tutorial, there might not be enough emphasis on the precise relationship between key factors such as temperature, pressure, and moisture content. As a result, students might only understand the principle on the surface and not understand how these factors interact to cause the corn to explode. 2. ** Skill development ** - Students were expected to master the basic skills of popcorn making through watching videos, such as correctly judging the timing of corn popping and understanding the effects of different heating methods (such as the heating of old-fashioned popcorn machines and the heating of modern home cooking methods) on popcorn making. However, from the perspective of teaching effect, due to the limitations of the video display, students might not be able to fully feel the details of the actual operation, such as the subtle changes in the state of the corn during the heating process, thus affecting the students 'comprehensive mastery of the production skills. ##2. Strengths of Teaching 1. ** Interesting presentation ** - Choosing popcorn making as the subject of the science experiment itself was highly interesting and could attract the attention of students. In the video, the process of popcorn turning from corn to fluffy and delicious popcorn was full of surprises, which helped to stimulate students 'curiosity and desire to explore scientific phenomena. 2. ** Principle combined with examples ** - In the teaching process, the principle of popcorn making was combined with practical examples, such as the working principle of the old-fashioned popcorn machine (the change in the pressure in the furnace caused the corn to pop) and the way modern families made popcorn. This combination helped students connect abstract scientific principles with reality, allowing them to better understand and remember them. ##3. Inadequacies in Teaching 1. ** Lacking interaction ** - The biggest limitation of video lessons was the lack of interaction. Unlike face-to-face teaching, it was impossible to answer the questions of the students in time, nor could it adjust the teaching rhythm according to the feedback of the students. For example, when the changes in the corn during the heating process were shown, the students might have a lot of questions, such as "Why hasn't the corn exploded at this time", but the video couldn't respond immediately. 2. ** Not enough experimental details are shown ** - In the demonstration of the popcorn experiment, some key experimental details may not have been fully demonstrated. For example, when introducing the differences between different types of corn to make popcorn, it was only briefly mentioned. The characteristics of different corn and the specific impact on the production results were not shown in detail. This might cause students to not have a deep understanding of this part of the knowledge. ##IV. Modification 1. ** Added design for the interaction segment ** - In the future, if the video teaching method was continued, an interaction session could be set up, such as setting up a question point in the video to guide the students to pause the video and think about the problem. Then, an online Q & A channel, such as a dedicated discussion area or an online Q & A platform, could be provided to answer the students 'questions in time. 2. ** Details of the optimization experiment ** - When remaking the video, he had to pay more attention to the details of the experiment. For key steps and details that were easily overlooked, close-up shots and slow-motion replays could be used. For example, when showing the impact of the internal structure of corn on popcorn production, the starch granules and moisture distribution inside the corn could be shown through animation or microscopic lens to let students understand the principle more clearly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
On the effectiveness of mini-novel teaching
The effectiveness of teaching mini-novels could be reflected in the following aspects: ** 1. Enlarge the "micro" environment and grasp the atmosphere ** The environment was an important component of a mini-novel. The description was extremely "subtle", concentrating the content of life on a specific "point". In teaching, one could grasp the atmosphere by magnifying this "micro" environment. For example, when teaching the mini-novel " Bridge," the teacher could insert sound effects, guide the students to read the sentences and appreciate the relevant pictures, watch the video, etc., so that the students could feel the wildness of the roaring flood and immerse themselves in the dangerous and tense atmosphere. From there, they could understand the role of the description of the natural environment in exaggerating the atmosphere and setting off the characters, as well as the significance of the description of the social environment in revealing the profound meaning of the work. ** 2. Combing the three elements of "micro" and grasping the plot ** The "small" of a mini-novel was mainly manifested in the fact that the three elements of environment, plot, and characters were the least. Teachers combing through these three elements in teaching would help students grasp the plot. This requires teachers to guide students to understand how to use the least elements to construct a story and experience its unique artistic features. Through the above methods, teachers can improve the effectiveness of teaching mini-novels and let students better understand and appreciate mini-novels. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Zhurong's scientific experiment on Mars
Zhurong conducted many scientific experiments on Mars. Zhurong carried six scientific payloads, including a multi-spectral camera, a sub-surface detection radar, a Mars surface composition detector, a Mars surface magnetic field detector, a Mars meteorologist, and a terrain camera, to carry out scientific experiments. It was mainly used to carry out surface composition, material type distribution, geological structure, and Mars's atmospheric environment. For example, using the data obtained by the multispectral camera, the international research team found evidence of the existence of an ocean in the northern part of Mars. Based on the observation data of the Zhurong rover, Chinese researchers found that the sand dunes in the six zones of Zhurong had crusts, cracks, agglomerations, hexagonal ridges, banded water marks, etc. Spectral data analysis found that the sand dunes were rich in water-bearing minerals such as water-bearing sulfuric acid, opal, and water-bearing iron oxide.It was inferred that the water-bearing characteristics of the sand dunes were due to frost or snowfall. This discovery provided key clues for understanding the history of Mars 'climate evolution and finding life in the future. In addition, Zhurong also carried detection equipment such as meteorology, geological, and physics, as well as a Martian ground penetrating radar to detect the distribution of underground water ice on Mars.
