Excellent topics of comprehensive practice in primary schools. Teachers need to do more research to evaluate their professional titles. Only when there are enough research topics will the promotion of professional titles become faster. The main research object of teachers is students. Let's take a look at the excellent topics of comprehensive practice in primary schools.
Excellent subject of comprehensive practice in primary schools 1 1. Activity background:
Although the history of plastics is not long since its birth, plastic products have spread all over the world and become something we can't live without. The invention of plastics has greatly facilitated human life, but it has also caused great pollution to the natural environment. Understanding plastics can not only strengthen children's hands-on ability and expand their knowledge, but also strengthen children's awareness of environmental protection in the process of activities. Therefore, this activity was designed.
Second, the activity objectives:
1, so that students have a good quality of caring about society and nature and strengthen their awareness of environmental protection.
2. Cultivate children's practical ability and innovative consciousness, and expand their knowledge.
3. Cultivate children's learning quality of observing, discovering and thinking, and their enthusiasm and confidence in participating in activities.
Third, the activity process: create an activity situation:
1. I'm glad to have another comprehensive practical activity with my classmates. Let's pay attention to life and go into science together.
The teacher said: Last week, I noticed a phenomenon on my way to and from work. In fact, this phenomenon usually occurs, but this time it touched me in particular. What is this? Let's take a look. Show me the photos.
Do you think this phenomenon is common in our life? Where did you get so many plastic bags? Have you ever seen this phenomenon? In Taizhou, there are many bad habits in life, which people have become accustomed to. What is a bad habit? Uncivilized and unreasonable habits. For example; Spitting, littering, etc.
But few people feel abnormal, right? But it is often because people don't agree and don't care that it will lead to serious consequences, right?
Now I'll dig an intelligence trap for my classmates to see if you will fall into it. How's it going? Dare to take it? Listen to the topic (Music 2): Is white paper and white cloth "white pollution" after being discarded? Students talk about their understanding of "white pollution". At present, "white pollution" puzzles many countries in the world, and it does bring us great problems, but this problem has been overcome by me.
I decided to propose to the United Nations Health Organization that all countries in the world ban the production of plastic products. what do you think?
Students will definitely express their views on the benefits of plastics. Teachers can also remind students in kind: guitar, skipping rope, etc.
Photos: blinds, TV, scooter, piano, car steering wheel, etc.
Teachers will paste the prepared teaching AIDS on the blackboard: eating, drinking, wearing, playing, musical instruments, decorative materials, transportation, household appliances, furniture, agriculture and so on.
The teacher said: It seems that plastics are really everywhere in our lives. Plastics are widely used in our lives. Does it have any special skills? Is its birth a curse or a blessing for us human beings? How's it going? Want to know more about plastics? Give us a theme for this activity first!
5. Create the name of the activity theme.
6. Give students time to think and discuss, and make clear what they want to explore most. The teacher then guides and appropriately guides the students to expand their thinking.
7. Communicate with the class and ask questions. The teacher wrote them one by one on the blackboard. Instruct students to summarize themselves.
8. Divide the problems into several categories. Please choose a topic that interests you and sit in a group. If there are too many people in a group, divide one group into two groups.
9. Students conduct research and discussion, and teachers go to various groups for guidance. Add background music.
10, students introduce the activity plan. Add background music to set off the atmosphere.
1 1. After exchanging the activity plan, the teacher will summarize it.
Excellent topics of comprehensive practice in primary schools II. Expected results of project design:
Our lovely hometown, Putuo, has many schools. In every classroom, the blackboard is indispensable, and of course, the blackboard is also inseparable. When class is over and on duty, students can often be seen cleaning the lower part of the blackboard, but they can't reach the upper part. In order to save trouble, some skip a little and brush a little, which often takes a lot of time in a small place; Some students moved to stools and stopped to clean them. They often cleaned one side and then jumped up and down to clean the other side. Sometimes they stagger on the stool, which makes people worry and has hidden dangers. Some students simply gave up, and when the teacher came to class, the blackboard was still full of words, which affected the class and brought great inconvenience to teachers and students. So we want to make a convenient blackboard brush model to bring convenience to all teachers and students.
Objective: To understand the shortcomings of blackboard brushes through practical activities, so as to find a suitable manufacturing method and make a model. In practice, cultivate our communication ability and cooperation spirit; Learn to discover, learn and solve problems, and be a small master of society.
Second, the main results:
In this comprehensive practical activity, all the members of our victory team have their own suitable jobs, actually tried various roles, experienced the hardships and happiness of the activity, and learned many skills that were not learned in class, and gained a lot. The specific report is as follows:
(1) We adopted the methods of field observation, questionnaire survey, interview and practice.
(2), activity research process:
Stage (1) investigates students and teachers who have used blackboard brushes, and understands how to use blackboard brushes.
After we determined the research topic, we conducted a questionnaire survey in the whole school.
Convenient blackboard brush questionnaire
Hello, class. We are members of the R&D and production team of convenient blackboard brushes. In order to study this topic more conveniently, we sent out such a questionnaire. Please be sure to fill in this volume. Thank you.
Check the following options.
1, did you clean the blackboard? A did () B didn't ()
Have you ever had any difficulty in cleaning the blackboard? A met () B didn't meet ().
Do you think our blackboard is well painted now? A is good () B is bad () C is average ()
4. Do you want to change our current blackboard brush? A hopes () B doesn't want () C doesn't matter ()
Short answer.
1. What difficulties did you encounter when cleaning the blackboard?
2. What kind of blackboard brush do you want?
Do you have any suggestions for us to design a new blackboard brush?
Investigate students and teachers who have used blackboard brushes and ask them about their use of blackboard brushes, so as to find out the shortcomings of blackboard brushes and study convenient blackboard brushes in a targeted manner. According to the survey, most students think that when cleaning the blackboard, the dust on the blackboard will get to their eyes; Short people can't brush high chalk; Some teachers have a hard time writing, and it is difficult to wipe it; When cleaning the blackboard, scattered chalk dust will get on clothes; The blackboard brush is not nailed firmly and is easy to fall off. They all hope that the blackboard brush can be elongated, light and durable, can absorb chalk dust, and is clean and convenient to wipe. Their views provide a good reference for us to make and study convenient blackboard brushes.
Stage (2) Ask relevant experts, teachers and students how to draw design drawings and make materials.
Knowing the shortcomings of the brush, we began to design the drawings of the brush. But how to design it? We're in trouble. So we split up, and one group searched the internet for information and related design drawings; One group went to interview related experts and teachers. On the Internet, we know that the design drawings should be:
1, there must be an exact proportion. No matter how the drawing is scaled, its absolute area remains the same.
2. The plan has three parts. The first part indicates the structure and size; The second part should indicate the specific shape and size, and the drawings should indicate the material specifications and process requirements; The third part marks the placement position of equipment and facilities.
We encountered some problems when interviewing teachers. We interviewed Mr. Yu, an art teacher, and Mr. Yu was not very clear about it.
I was going to interview the relevant experts, but I didn't find them, so I had to study them myself.
Our group members discussed and studied together, and everyone designed their own convenient blackboard brushes when they went home. After returning to the classroom, we will discuss compiling and determining the final production drawings.
Attachment: Drawings (sketches) convenient for the development and production of blackboard brushes.
(Draft 1)
The blackboard brush is about 13 long and 5 cm wide.
The width of the metal strip is about 1cm.
The metal rod can be telescopic, and the total length can reach about 50 cm.
(Sketch 2)
The blackboard brush is about 13 long and 5 cm wide.
The metal bar can be telescopic, with a total length of about 50 cm and a width of about 1 cm.
Stage (3) Make a convenient blackboard brush model.
After confirming the drawings, we can start making them. First of all, we should go shopping to buy the materials we made. We found several hardware stores, asked the shopkeepers, and finally bought movable aluminum alloy bars, as well as all-purpose glue, soft iron sheets and other materials. A group of us started doing it at our classmates' house on weekends. In the process of production, we met some difficulties:
When we made it, we found that the metal rod was elongated and thin and thick. We used the blackboard brush to paste the thinnest part on the outside, but it was too thin, and the blackboard brush was heavy, so it broke down several times. The second time, we lengthened the metal bar and glued the slightly thicker end to the shell of the blackboard brush, and it was finished. A few days later, I didn't expect the convenient blackboard brush to break because of insufficient adhesion (as shown in sketch 2). Because the metal strip convenient for the blackboard brush is only three centimeters attached to the blackboard brush shell, it will naturally fall off, so we decided to attach the metal strip to the blackboard brush shell (such as sketch 1). In this way, our convenient blackboard brush was finally completed. I took it to school and tried it. It didn't break. Great, the students are very happy.
After everyone's efforts, many things have been grinded, and our convenient blackboard brush is a success.
Promote, display and sell our convenient blackboard brushes.
In order to let all teachers and students know the function of the convenient blackboard brush and learn to use it, let our convenient blackboard brush enter every classroom, and we go into every classroom to publicize, display and sell our convenient blackboard brush. In the promotion, some students think that this blackboard brush is good, and it can be extended and retracted freely, which is very convenient; Some people say that we will never have to stand on a stool to clean the blackboard again; Some junior children also asked if they could send us one. We really need it. Some students also gave us advice that the handle inside the blackboard brush must be of good quality and durable, so that students will like it. ...
It seems that our blackboard brush has been recognized by our classmates. We did it!
Stage (5) Sort out relevant information and write a summary report. Learn how to apply for a patent.

Third, reflection activities:
We are children who grew up under the careful care of our mother and the hard training of our teachers. We have a sense of small masters in the new century, but we lack the actions of small masters. There are many ideal strategies, but they can't be practiced. Have the desire to succeed, but lack many skills to lay the foundation for growth. This time the school organized teachers to guide us to play a leading role in comprehensive practical activities, which really benefited us a lot.
1, our activities are purposeful, planned and organized. It has cultivated our serious working attitude and scientific research spirit.
2. In the research of small topics, we can learn to use the book knowledge we have learned, exercise our hands-on ability, give play to our imagination, and cultivate our ability and consciousness of loving science and technology, so that we can feel the happiness of research and the successful experience of creation in the research process, thus enhancing our self-confidence.
3. In every classroom of the school, we observe on the spot and find out the disadvantages of blackboard brushes; Through the questionnaire survey, I understand their voices; Test students' practical ability through production; By going out to buy materials, I learned that the goods I bought should not only be cheap and good, but also be of excellent quality ... We believe that our activities have played a role in invention and innovation and enhanced people's awareness of innovation.
Through this activity, we have enriched our after-school life, improved our abilities of practical operation, scientific research, writing and adapting to society, cultivated our spirit of partnership, and exercised our practical ability and perseverance to overcome difficulties.
After this activity, we deeply realized the importance of a person's ability. Learn to listen, learn to cooperate, be good at accepting good advice from others and constantly improve yourself.
6. Learn to use tools such as hammers, pliers and screwdrivers to cultivate our hands-on ability.
7. Because the time of this activity is very tight, and it is the first time to do it, everyone has worked hard and suffered from the pressure of many parents. However, we have done this seriously and successfully.
