The curriculum resources of comprehensive practical activities lie in students' curious nature and teachers' keen thinking. There is a poem that says well, "How can the canal be so clear, because there is running water at the source". The curriculum resources of comprehensive practical activities are dynamic. It is in a state of continuous generation and is a kind of "loose-leaf resource".
The implementation of comprehensive practical activities is oriented to students' complete life field, which not only pays attention to their actual needs, respects their hobbies, but also takes into account their long-term development. It gives students a broad world, gives them the opportunity to go out of the classroom to the society, provides an open space for their development, and realizes the publicity and healthy development of students' personality in the process of deepening activities. This semester, our class has made some progress in the development, implementation, discussion, evaluation and management of comprehensive practical activities.
First, the development of resources is "in-depth"
The curriculum resources of comprehensive practical activities lie in students' curious nature and teachers' keen thinking. There is a poem that says well, "How can the canal be so clear, because there is running water at the source". The curriculum resources of comprehensive practical activities are dynamic. It is in a state of continuous generation and is a kind of "loose-leaf resource". This semester, our class has set up two theme activities. According to the theme stipulated at the beginning of the semester, it is "the study of traditional festivals", that is, the Mid-Autumn Festival research activities were carried out; The second theme is "great maternal love". According to the age characteristics of students, a series of activities were carried out, such as caring for mothers, singing for mothers, and holding maternal love handwritten newspapers.
Second, the implementation of the curriculum is "fresh"
This semester, in our activities, students' comprehensive abilities such as practical ability, practical ability, research ability and innovation ability have been improved, mainly in the following aspects:
The first is to understand the origin of Mother's Day in activities. The second week of May coincides with Mother's Day, so students are organized to study the origin of Mother's Day. In the exchange of achievements, students report in various forms, not only in the form of manuscripts in the past, but now they can report their achievements in various forms such as stories, introductions, recitations and explanations. Through activities, improve students' ability to collect, organize and exchange information, and let students have a better understanding of Mother's Day.
The second is to cultivate social skills in activities. For example, "Understanding Motherly Love" organized some students to collect stories about mothers; In "praising maternal love", half of the students are required to collect and try to write poems praising maternal love; Comment on Motherly Love reports what you want to say to your mother in the form of handwritten newspapers or cards, and expresses your love for your mother in Comment on Motherly Love.
Although most students are nervous at first when they collect or express their love for their mothers, through this series of activities, students can initially master the methods of participating in social practice and sorting out information. At the end of the activity, they all felt emboldened and dared to tell their mother the truth, which showed that their ability to communicate with others was really improved during the activity. Moreover, in the process of learning to write investigation reports, I have initially developed a correct learning attitude and the ability to explore problems.
The third is to improve psychological quality in activities. In view of the poor psychological quality of students, the sixth grade students carried out the theme activity of "Understanding and Appreciating Mothers", which enabled students to have a more comprehensive and objective understanding of their mothers, love their mothers more and increase their feelings.
The fourth is to enhance the awareness of innovation in activities. For example, in a series of activities such as making greeting cards and learning to write poems, students can learn to observe their mother's life, find their own problems, and stimulate their interest in hands-on practice, so as to develop their practical ability and enhance their innovative consciousness.
Third, the evaluation method is "diversified"
The evaluation of comprehensive practice course should pay attention to students' learning state, vitality, innovative consciousness and ability development, so the evaluation of students in our school is carried out from three aspects: knowledge and skills, process and method, emotion and attitude. After each theme activity, the leaders of each activity group organize members to summarize, reflect and evaluate the activity. There are three evaluation methods: student self-evaluation, peer evaluation and teacher evaluation, which are driven by evaluation to promote students to carry out the next round of activities.
Fifth, the organization and management should be "orderly"
Because comprehensive practical activity is an open, generative and comprehensive course, I attach great importance to the design and guidance of theme activities in the activity, and every activity is orderly. In the process of implementing each activity theme, I can enrich the activities and ask students to carry out activities such as activity design, data collection, investigation, design, production, performance, summary, communication, defense and reflection as much as possible; Pay attention to the accumulation of process data and sort it out.
Students are the biggest beneficiaries, because comprehensive practical activities open the wings of imagination for them and build a platform for them to show themselves.
Through a series of attempts, we deeply realize that there is no good or bad practice. As long as it is true, students have gained some gains in ability, attitude and emotion, and their emotions have been cultivated. This is success, and it is the success of our education and guidance! You know, close contact comprehensive courses must be based on practice, and only by doing can you "learn"! Yes, only by continuous learning can we be close to perfection. As long as we have the courage and confidence to embark on a road with our own characteristics! The result of these activities is always win-win, isn't it?
The second part, "Synthesis and Practice", is a kind of learning activity with the participation of teachers and students, which is an important way to help students accumulate experience in mathematics activities. Comprehensive practice can also be understood as mathematical inquiry or mathematical modeling activities, which refers to the process in which students comprehensively apply their learned mathematical knowledge, ideas and methods to solve some mathematical or practical problems. In the design and implementation, we should pay special attention to five links: the choice of problems, the development process of problems, the way of students' participation, the cooperation and exchange of students, the display and evaluation of the process and results of activities; And the requirements of teacher-student interaction in the activity. In teaching design and implementation, we should pay attention to the following points:
First, closely integrate with practice and carefully design problems
The so-called "design problem" is the activity content of designing "synthesis and practice". A good "comprehensive practice" activity should have the following characteristics: first, it is realistic; The second is openness; The third is comprehensiveness; The fourth is practicality. Among them, truth is the premise, openness is the guarantee, comprehensiveness is the foundation, and practicality is the foundation.
For example, estimate corn income.
1. Students should do a good job of investigating some knowledge and information about planting corn before class.
2, reading comprehension, reading questions, to understand the information about Mr. Wang's corn planting, corn production and corn sales, so that students can fully contact and find problems in real life and improve their ability to analyze and solve problems.
3. Solve problems in groups. Put forward the requirement of "group cooperation, help uncle Wang calculate", and let students cooperate to solve three problems in the book. On the basis of the above analysis, let students solve problems through cooperative discussion, which not only cultivates students' spirit of cooperation and communication, but also strengthens students' ability of independent inquiry. Work in groups to help Uncle Wang calculate with a calculator: (1) What is the corn income this year? (2) What is the average income per hectare? (3) How much more revenue is expected than this year? Then exchange the calculation methods and estimation results of each group. Students should be given ample opportunities to exchange different algorithms.
Second, carry out extensive practice and strengthen cooperation and exchanges.
The "extensive" here refers to both "the sufficiency of the process" and "the diversity of forms", and should also include "full communication". For example, in the activity of paving Yong Road, the following links were designed:
(1) Understanding and exchanging information
Investigate the relevant information of floor tiles and exchange the problems of selecting floor tiles. By investigating and reporting information, students can understand the size of flower beds, the location of paved roads and the necessity of using square floor tiles. then
(2) Discuss the issues of election and transfer.
After group discussion, we decided to choose a floor tile with a side length of 25 cm, and explained the reasons. (1 m2 is exactly 16 yuan).
(3) Solving problems
To solve this problem, firstly, the area of the permanent road and the area of each brick are required, and then the area of the permanent road/the area of each floor tile is used to calculate the number of required floor tiles. Then work in groups to discuss the calculation, and students choose their favorite method to calculate. Then report the evaluation to the whole team.
Through the completion of these three tasks, we can achieve "the whole process", "various forms" and "full communication"
Third, pay attention to reflective evaluation and improve practical wisdom.
The process of "doing mathematics" in mathematics practice is the process of making students experience mathematics, apply mathematics and reflect on mathematics. So, let students try it themselves, let them find problems in confusion, ask questions, learn to reflect, practice and summarize, and form correct conclusions. For example, in "2 1 point game":
Activity 1: Beginners hit the road.
1. Find it: ① Find two cards and work out 24. (2) add a card to calculate 24.
2. Give it a try: play three cards and count as 24.
3. The basic method of "24-point" small settlement: according to the numbers on three cards, select two numbers for the first operation, and perform the second operation with another number to make the calculated number 24.
Activity 2: Expert demonstration.
1, students choose three cards and work out 24 cards;
2, mutual calculation at the same table;
3, the whole class group communication.
Through activities, let students feel some ways to calculate 24 with three cards. At the same time, there are sometimes many ways to cultivate students' interest in learning mathematics when they know how to calculate 24 with three cards. )
Activity 3: main ring.
1, try four cards to calculate 24.
2. Group activities:
(1) required question: each team draws lots to choose a question number, and the corresponding four numbers will solve the "24 points" problem.
(2) Grab the answer: use four numbers to calculate 24 points within the specified time, and encourage various methods.
(3) Choose the answer: the question is divided into three questions: one-star question and two-star question, so that each group can choose freely, and the right answer will be rewarded, and the wrong answer will be reversed.
Form evaluation in the process of activities, help students to reflect on their own quality and effect in "comprehensive practice" activities, and explore the lessons of success or failure, then students' thinking will develop at a higher level, which is conducive to the formation of mathematical literacy and practical wisdom.
The comprehensive practice of primary school mathematics is still a new course and will continue. We will continue to learn, improve and gradually improve, so that practical activities can really promote the development of students, so that students can really learn valuable mathematics in practice, so that everyone can get the necessary mathematics, so that different people can get different development in mathematics.
