Elementary school integrated practice excellent subject
Elementary school integrated practice excellent subject, for teachers want to assess the title, you need to do more research, only research topics enough, then in the promotion of the title will become a little bit faster, the teachers are the main object of research is the students, the following look at the elementary school integrated practice excellent subject.
Activity Background:
Plastic from the birth of the present is not a long history, but the plastic products have been all over the world, and has become an inseparable thing in our daily lives. The invention of plastics has greatly facilitated human life, but also caused great pollution to the natural environment. Recognizing and understanding plastics not only enables children to strengthen their practical ability and expand their knowledge, but also strengthens their awareness of environmental protection in the process of the activity. Therefore, the design of this activity.
Second, the activities of the objectives:
1, so that students have to pay attention to society, pay attention to the good quality of nature, to strengthen the students' environmental awareness.
2 、Cultivate the children's practical ability and sense of innovation, expanding knowledge.
3 、Cultivate children's observational skills, good at discovering, good at thinking about the quality of learning and participation in activities, enthusiasm, self-confidence.
Third, the process of activities: create the situation:
1, I am very happy to have a comprehensive practical activities with the students, let's pay attention to life, into science.
Teachers said: In the last week, I noticed a phenomenon on the way to and from work, in fact, this phenomenon usually exists, but this time extraordinarily touch me, what is it? Let's take a look. Show the photo.
2, you think this phenomenon in our lives more? Where are so many plastic bags? Have you ever had this phenomenon? In our Taizhou, there are a lot of bad habits in life people have taken for granted. What do you mean by bad habits? Uncivilized, unreasonable habits. For example; (let the students say) spitting, throwing garbage etc.
But few people feel abnormal, is not it? But often it is precisely because people do not think, do not care that can lead to serious consequences, you say right?
3, now I give students to dig an intellectual trap, see if you will fall into it? How about it, do you dare to take it? Please listen to the question (under the music 2): white paper, white cloth waste is not "white pollution"? (The students said that they understand the "white pollution") At present, "white pollution" plagued many countries in the world is really a big problem for us humans, but this problem was overcome by me.
I decided: to the United Nations Health Organization initiative: all countries in the world to ban the production of plastic products, you see how?
4, students will certainly be on the benefits of plastic to express their views. Teachers can also take physical objects to the students to prompt: guitar, jump rope, etc..
Photos: blinds, TVs, scooters, pianos, car steering wheels and so on.
Teachers will prepare teaching aids on the board: food, drink, clothing, play, musical instruments, decorative materials, transportation, household appliances, furniture, agriculture, etc..
Teachers say: it seems that plastic is really everywhere in our lives. Plastic is so widely used in our lives, it is not what special skills? Its birth to our humanity in the end is a disaster or a blessing? How is it? Want to know more about plastic? First give us a theme for this activity!
5, to establish the name of the theme of the activity
6, to give students time to think about the discussion, clear what they want to explore the most. Teachers go down to guide and guide the students to expand their ideas appropriately.
7, the whole class to communicate and raise questions. Teachers will write them one by one on the blackboard. Guide the students to generalize and organize themselves.
8. Divide the questions into several categories. Ask the students to choose their own topics of interest and sit in a group. (If there are too many people in one group, divide one group into two).
9, the students to research and discuss, the teacher to the groups to guide. Add background music.
10, the students introduced the program. Add background music to set the mood.
11, after the exchange of activity programs, the teacher summarizes. After class, when doing duty, you can often see students wipe the blackboard, wipe the bottom half, can not reach the top half. Some of them in order to save time, jumping wipe, jump a little wipe, often a small piece of place takes a lot of time; some students move to the stool stopped at the top of the wipe, often wipe this side, and then jump up and down to wipe the other side, sometimes feet on the stool on the wobbly, so that people look worried, there is a hidden danger of insecurity; there are also students simply do not care about it, the teacher came to class or a full board of words, affecting the teacher and the students. Classes, to teachers and students brought great inconvenience. So we want to make a convenient model of the blackboard brush, to the whole school teachers and students to bring convenience.
Purpose: Through practical activities, understand the shortcomings of the blackboard brush, so as to find a proper production method and make a model. In practice, to cultivate our ability to interact, the spirit of cooperation; learn to discover, research, problem solving and other abilities, to be a small master of society.
Second, the main results:
In this comprehensive practical activities, all the members of our Victory Squad, everyone has their own appropriate work, and actually try out a variety of roles, experience the activities of the hardship and happiness, learned a lot of classroom learning can not be learned skills, a lot of harvest. Specific reports are as follows:
(a), our practical activities research using field observation, questionnaires, visits, practice and other methods.
(2), the activities of the research process:
Stage (1) investigation of students and teachers who have used the blackboard brush, to understand the use of the blackboard brush.
After we determined our own research topic, we conducted a questionnaire in the whole school.
Questionnaire on Convenient Blackboard Brushes
Hello, students. We are members of the research and production team of the convenient blackboard brush, in order to more convenient research on this topic, we came out with such a questionnaire, please make sure that students fill out this volume, thank you.
Tick the following options.
1, you have wiped the blackboard? A wiped ( ) B not wiped ( )
2, in your wiping the blackboard encountered difficulties? A encountered ( ) B did not encounter ( )
3, you think our current blackboard brush is good? A good ( ) B not good ( ) C general ( )
4, you want to change our current blackboard brush? A希望（ ）B不希望（ ）C无所谓（ ）
Short answer.
1, what difficulties have you encountered when you wipe the blackboard?
2. What kind of blackboard brush do you want?
3. What suggestions do you have for us to design a new blackboard brush?
Investigation of students and teachers who have used the blackboard brush, to learn from them about the use of the blackboard brush, in order to have found the shortcomings of the blackboard brush, so that we have targeted research to facilitate the blackboard brush. From the survey to reflect the situation, the general students think that when wiping the blackboard there is dust on the blackboard will get to the eyes; short brush can not be high chalk words; some teachers write very hard, wipe when it is difficult to wipe; wipe the blackboard, scattered chalk dust will get to the clothes; blackboard brush nailed to the ground is not solid, it is easy to come off and so on the difficulties? They all hoped that the blackboard brushes could be elongated, lightweight, durable, absorb chalk dust, and be clean and convenient to erase. Their opinions are a good reference for us to make and study the convenient blackboard brush.
Stage (2) Consult with relevant experts, teachers and students on how to draw the design, and the materials to make it.
Knowing the shortcomings of the chalkboard brush, we started to design the drawing of the chalkboard brush. But how to design it? We encountered difficulties. So we divided into action, a group of online search for information, looking for information about the design of the drawings; a group to interview relevant experts and teachers. On the Internet we know that the design drawings to do:
1, to have the exact proportion. Regardless of how the drawings are scaled, its absolute area remains unchanged.
2, the plan shows the contents of three parts, the first part of the structure and size; the second part of the specific shape and size, the map needs to indicate the specifications of the material and process requirements; the third part of the standard equipment and facilities placed in the location.
To interview the teacher encountered some problems, we interviewed the art teacher Yu, Yu teachers are not very clear about this.
Originally prepared to go to interview the relevant master, but did not find, only their own research.
Members of our group together to discuss, research, each home to design a convenient blackboard brush in their minds. Back to the classroom, and then discuss the repertoire, to determine the final production drawings.
Attachment: research and production drawings of the convenient blackboard brush (sketch)
(Sketch 1)
The blackboard brush is about 13.5 centimeters long and five centimeters wide
The metal rod is about 1 centimeter wide
The metal rod can be extended and retracted, and the full length can be up to about 50 centimeters
(sketch 2)
The blackboard brush is about 13.5 centimeters long and five centimeters wide
The metal rod is retractable and extends to a full length of about 50 centimeters and a width of about 1 centimeter
Stage (3) Make a model of a handy chalkboard brush.
After determining the drawings to make, we are ready to make. First of all, we have to go to the street to buy the materials for making. We looked for several hardware stores, ask the owner, finally bought the aluminum alloy rod that can be moved, in addition to universal glue, soft iron and other materials. A group of us to use the double holiday in the students' home began to make up, in the production, and encountered some difficulties:
When we make, found that the metal rod after stretching there are thin and thick, we will be the thinnest . The place and the blackboard brush outer guest stick, but it is too thin, the blackboard brush weight heavy, a few times after the problem. The second time, we will extend the metal rod, the slightly thicker end will be glued to the chalkboard brush outer shell above, we finished. A few days later, I did not expect the convenience of the blackboard brush is bad, check the reasons for the original is not enough adhesive force, (such as sketch two) because we do to facilitate the blackboard brush the metal rod and the blackboard brush shell only stick three centimeters away from the natural fall, we decided to stick the metal rod and the blackboard brush shell long all the way to stick, (such as sketch one) in this way, our convenience of the blackboard brush is finally completed. Took the school to try, the rod did not break, great, the students are very happy.
After everyone's efforts, the effort is not unmerited, our convenient blackboard brush to do a success.
Phase (4) publicize, show and sell our handy blackboard brush.
In order to make the whole school teachers and students understand the role of the convenient blackboard brush, learn to use the convenient blackboard brush, so that our convenient blackboard brush into each classroom, we went into each classroom to publicize, display, marketing our convenient blackboard brush. In the promotion of publicity, some students think that this blackboard brush is good, can be freely retracted, very convenient; some say that we wipe the blackboard no longer need to stand to the bench to wipe; some of the lower grades children also said that we can not send us a, we are very much in need of; some students also gave us advice, said that the handle in the chalkboard brush must be of good quality, to be strong, durable, so that the students will like! ......
It seems that our chalkboard brush has been recognized by the students. We succeeded!
Stage (5) Organize relevant information and write a summary report on the subject. Understand how to apply for a patent.
After making the handy blackboard brush, we went online to find out about applying for a patent. From the Internet to find:
