Comprehensive practical activity refers to a practical curriculum model based on students' interests and direct experience, with various realistic, comprehensive and practical problems closely related to students' study life and social life as the content, and with research-oriented learning as the leading learning mode, with the main purpose of cultivating students' innovative spirit and practical ability and embodying students' comprehensive application of knowledge. First, raise awareness ideologically.

Mathematics Curriculum Standard points out that mathematics knowledge comes from life and is applied to life. Mathematical practice is to verify this sentence. Now many teachers have realized its position and role in teaching, but there are only two practical activities in the textbook each semester, which can not meet the actual needs of teaching. Teachers should lead students out of the classroom, contact the society, broaden students' horizons, increase students' information, and let them see that mathematics is an indispensable and powerful tool in life.

According to the characteristics of first-year students, combined with what they have learned, students are encouraged to contact with real life and carry out social practice activities. We designed two themes: 1. Investigation on output value of rural crops. 2. Investigate parents' support for students' study and school education. Through this semester's mathematical practice, we think that teachers have a long way to go to carry out mathematical practice. We should constantly study and think, explore and try to build a teaching mode of mathematical practice activities with personal characteristics, improve students' mathematical ability and work hard for their all-round development.

Second, cultivate students' abilities.

1, observation ability. For example, after learning to discover laws and observe objects, students often pay attention to observing things in life, find problems, ask questions, discuss and study problems, and their observation ability is also improved.

2. Hands-on operation ability.

3. Communication and presentation skills. Mathematics practical activity class provides students with a broad space for cooperation and communication. Mathematical communication is mainly manifested in learning to cooperate with people, being able to communicate the process and results of thinking with people, and initially forming the consciousness of evaluation and reflection.

4. Question thinking ability. In the activity of finding the corner of life, students point out the existence of the corner with some objects around them. However, several students observed it carefully. They found that the two sides of many corners in life are not straight enough, the vertices are not sharp and a little dull, and questioned that the corners in life are not as standardized as described in math textbooks. After intense discussion, verification and communication, it is concluded that there is a certain connection and difference between the apparent angle of objects in life and the strictly defined angle in mathematics class.

5. Creativity. Traditional teaching methods and answers to questions are often single and absolute, which is not conducive to cultivating students' creative thinking. The characteristic of creative thinking is that it can analyze problems from multiple angles, levels and sides, thus producing many associations.

Third, the relationship between teachers and students in activities

In comprehensive practical activities, teachers are no longer teachers, but promoters. The key to being a facilitator is to promote students' autonomous learning, urge students to feel and experience, observe experiments and explore discussions. Teachers become the most reliable source of psychological support for students. In comprehensive practice, students are no longer passive recipients, but active subjects, and researchers who ask questions and try to solve them. The relationship between teachers and students is cooperative, * * * is committed to the research process of problems, and * * * enjoys the joy of success.

Fourthly, several problems should be paid attention to in the teaching of mathematical practice activities.

1. Make a feasible activity plan.

Teachers should fully tap the educational factors that can be used in teaching materials, closely connect with students' learning and life reality, as well as students' knowledge level and cognitive ability, and strive to achieve clear goals and careful planning.

2. Carry out practical activities in line with students' age characteristics.

Junior high school students' subjective consciousness is gradually enhanced, and they have a certain mathematical knowledge base and social life experience. Therefore, activities such as specific operations, field measurement, visits and small-scale experiments are generally carried out to gradually cultivate students' awareness of discovery ability, exploration ability and application ability.

3. Change teachers' roles and highlight students' dominant position.

Mathematics comprehensive practice requires teachers to return the initiative of learning and the right of personality development to students, so that students can play a leading role. Teachers should change from imparting knowledge to organizers, instructors and participants of activities.

4. Do a good job in the evaluation of comprehensive practical activities.

Objective and correct evaluation has certain guidance and incentive, so we should actively do a good job in the evaluation of comprehensive practical activities and play a positive incentive role.

2. Comprehensive practical activity plan

I. Design Theme With the improvement of people's living standards, a healthy and elegant living environment has become the pursuit of more and more people. Students are the masters of the future, as well as the creators and enjoyment of a better life. They should cultivate health awareness, environmental awareness and aesthetic ability from an early age, and this task undoubtedly falls on our educators. We carry out comprehensive practical activities of flower conservation and healthy life, which is to let students master the knowledge about flowers on the basis of consulting materials, maintaining flowers and thinking, so as to beautify healthy life and improve their ability of thinking, communication, appreciation and debate.

Second, the design ideas:

This activity should be closely linked with students' real life. By observing flowers and plants, consulting materials, investigating and visiting, and caring for flowers and plants personally, students can master more knowledge of flowers and plants, know the advantages and disadvantages of caring for different flowers and plants, and improve their aesthetic ability and ability to beautify their lives.

1, through consulting materials, exchange and discussion, establish the theme of comprehensive practical activities this semester.

2. Through observation and consultation, learn about the relevant knowledge of flowers and plants that you are interested in at home or at the homes of relatives and friends, and communicate in groups.

3. Design the health and beautification standards that each functional room in your home needs to meet, and consult or visit experts online to learn about the relevant functional flowers and plants.

4. Group communication. Select the members of the group to communicate on behalf of the group in class.

5, according to their own needs and on behalf of the promotion of the situation, using their favorite' flowers and plants', and write a good observation diary.

Three. moving target

1, knowledge and ability: let students pay attention to and understand the relevant knowledge of flowers and plants, be able to choose reasonable methods to consult edited materials, master conversation skills during the visit, listen politely to the interviewees' conversations and pay attention to making records, master the methods and skills of maintaining flowers and plants, and improve their ability to dress up and beautify their lives.

2. Processes and methods: Class is mainly group activities, and family or society is mainly individual and group visits. Carry out various activities through consultation, research, investigation and interview, and practice.

3. Emotion, attitude and values: Through the knowledge of flowers and plants and the improvement of people's living standards, let students know that planting flowers and raising grass has become a part of people's lives. Flowers and plants are friends of human beings, which can cultivate people's sentiments, entrust people's feelings, beautify, purify and healthy our living environment. Each of us should understand the knowledge of flowers and plants, actively participate in planting flowers and protecting them, and beautify our healthy life.

Four. Highlights and difficulties of the activity

Key points:

1. Learn about flowers and plants by consulting materials, including their living habits, maintenance points, indoor applications, etc.

2. Conduct surveys, interviews and field trips to understand the ecological habits of flowers and plants, the key points of conservation, the advantages and disadvantages to the environment, and cultivate the ability to conserve flowers and plants, the awareness of beautifying the healthy environment and the awareness of aesthetic design.

Difficulties:

1. After consulting and refining related flowers and plants, collect them by classification or draw handwritten newspapers.

2. Investigation visits and field visits and writing investigation reports.
