Home School Water Consumption Investigation Teaching Plan and ReflectionThe following is a lesson plan and reflection on the water consumption survey in the home school:
##1. Home and School Water Consumption Investigation Teaching Plan
###(1) Teaching objectives
1. * * Knowledge and Skill Target **
- Students can master the basic methods of investigating water consumption, such as data collection, recording, etc.
- Learn to use appropriate tools (such as measuring cups) to measure the amount of water.
2. * * Course, Method, and Target **
- Through field investigations of the amount of water used in different scenarios at home and school (such as kitchen, bathroom, campus cleaning, etc.), students were trained to observe and analyze problems.
- They could sort out and analyze the collected data and draw preliminary conclusions.
3. * * Emotions, attitudes, values, goals **
- To enhance the students 'awareness of water conservation and to recognize the preciousness of water resources.
- Cultivate students 'cooperative ability and sense of responsibility, and actively participate in the practice of water resources protection.
###(2) Difficulties in Teaching
1. * * Teaching Focus **
- Master the specific process and method of investigating water consumption.
- Accurately collect and record water consumption data.
2. * * Teaching Difficulties **
- How to guide students to analyze the reasons behind the data, such as the impact of different seasons and different usage habits on water consumption.
- According to the results of the investigation, effective water conservation suggestions were put forward.
###(3) Teaching Method
Teaching method, field investigation method, group cooperation method, and discussion method.
###(4) Teaching process
1. * * import (5 minutes)**
- By showing some pictures or videos of water-scarce areas, the students would pay attention to water resources. Then they would ask,"Our families and schools use water every day. How much water do we use? How should we investigate?"
2. * * Knowledge explanation (10 minutes)**
- Explain the basic concept of water consumption survey, including the scope of the survey (household and school) and the subjects of the survey (such as water faucet, water dispenser, flushing toilet, etc.).
- It introduced some tools for measuring water consumption, such as measuring cylinder, measuring cup, etc., and briefly demonstrated how to use them.
- He explained how to record data, such as creating a table to record the date, location, water equipment, water consumption, and other information.
3. * * Group allocation and task arrangement (10 minutes)**
- The students were divided into several groups, such as the family survey group and the school survey group. Each group was further divided into different tasks, such as measuring the water consumption in the kitchen, the water consumption in the bathroom, and so on.
- Give each team a task, specify the time frame of the investigation (such as one week), the specific content of the investigation (the frequency of use of each water equipment and the amount of water used each time), and so on.
4. * * Field Investigation (20 minutes)**
- Each group carried out a water consumption survey in the family or school according to the task arrangement.
- Guide students to use measuring tools correctly and record data accurately.
5. * * Data analysis (15 minutes)**
- Each group would sort out the data they collected and summarize it into a table or chart.
- Guide the students to analyze the data, such as finding out the equipment that used the most water, the difference in water consumption at different times, and so on.
6. * * Discussion and Exchange (15 minutes)**
- He organized groups to discuss, and each group shared their findings and analysis conclusions.
- Based on the results of the survey, the students were guided to discuss ways to save water at home and school, such as turning off the tap in time and using water-saving appliances.
7. * * Wrap-up (5 minutes)**
- The teacher summarized the entire teaching process, emphasized the importance of water conservation, and evaluated the students 'investigation activities to encourage students to actively practice the concept of water conservation in their daily lives.
##2. Reflection on Teaching
###(I) Success
1. * * Cultivation of practical ability **
- Through the field investigation of household and school water consumption, students were allowed to participate in the process of data collection and analysis, effectively improving their practical ability and hands-on ability.
- This practical teaching method also allowed students to have a more intuitive and deeper understanding of the use of water resources.
2. * * The embodiment of cooperative learning **
- In the process of assigning tasks and completing the investigation together, students learned to cooperate with others and cultivate teamwork.
- The communication and sharing between different groups also broadened the students 'thinking horizons, allowing them to look at water consumption from different perspectives.
3. * * Enhanced awareness of water conservation **
- The entire teaching process revolved around the investigation of water consumption and finally came down to the theme of water conservation. During the investigation and analysis, the students naturally strengthened their awareness of water conservation.
###(2) Deficiency
1. * * Limitations of investigation tools **
- During the actual investigation, it was found that some measuring tools (such as measuring cups) had limited measurement ranges, and the measurement of some larger water consumption (such as school swimming pool water) was not accurate enough, which affected the accuracy of the data.
2. * * The rationality of the time arrangement **
- In the field investigation, due to the large number of water facilities in the family and school, the situation was more complicated. The investigation time arranged for the students was slightly tight, resulting in some groups not being able to collect sufficient data.
3. * * The lack of in-depth analysis **
- In the data sorting and analysis process, although the students could find some superficial phenomena, such as the equipment that used the most water, they did not dig deep into the deeper reasons behind the data (such as the influence of social and cultural factors on water usage habits).
###(3) Enhancement measures
1. * * To improve measuring tools **
- For the measurement of larger water consumption, one could find or make a larger measurement tool, or use a combination of estimation and accurate measurement to improve the accuracy of the data.
2. * * Time-based optimization **
- In the next lesson, the time for the field investigation should be appropriately extended to give the students more time to collect data to ensure the comprehensiveness of the investigation.
- At the same time, in the teaching process, the time ratio of each link should be reasonably arranged to avoid the situation of loosening the front and tightening the back.
3. * * Guiding in-depth analysis **
- In the data analysis section, teachers can set some in-depth questions, such as "Why is the water consumption of toilets in different households different?" He guided the students to think deeply about the reasons behind the data and improve their analytical skills.
