First of all, there is a clear purpose of the activity.
All mathematical practice activities have the same purpose: to cultivate students' ability to analyze and solve problems by using mathematical knowledge; Through a practical activity, let students realize the role of mathematics knowledge in life, and enhance their confidence in learning mathematics well and their awareness of using mathematics. However, because mathematical practice can involve all fields of life and its purpose is very broad, I simply divide mathematical practice into several categories: (1) Consolidating knowledge. (2) cultivate interest classes. (3) Ideological education. Before the activity, teachers must design the purpose of the activity, which is the premise of successfully carrying out practical activities.
Second, make a practical activity plan.
As the guide of practical activities, teachers are the leaders of students' practical activities, and teachers should do a good job in guiding every step of practical activities. This requires teachers to comprehensively consider every step of this activity, formulate a reasonable and operable activity plan, and determine the scope, object and time of the investigation, so as to guide students to successfully complete the activity.
Third, make full preparations for activities.
The following work should be done in the preparation stage of the activity:
1. Break into groups. Group cooperative learning is an effective way for students to learn and can cultivate their sense of cooperation. Group is the basic unit of mathematics practice, generally 4 ~ 6 people are the main ones, and students can combine freely when grouping.
2. Make a group activity plan. Group is the basic unit to carry out mathematical practice activities. After the group is established, the activity plan of the group should be made according to the general outline formulated by the teacher. Senior students can present the plan to the teacher in the form of a written report, and the teacher will guide and improve according to the plan made by the students. Teachers can give guidance from the aspects of time arrangement, division of labor among group members, where to go and what to do, how to do it, etc., so that the group can have a clear purpose when carrying out activities and ensure the smooth progress of group investigation and research.
For the formulation of the plan, each group can learn from each other and learn from each other's strengths.
3. Prepare necessary tools according to the plan. On the one hand, teachers explain the necessary tools to students according to their own master plan, on the other hand, the group prepares the necessary tools according to the activity plan formulated by the group. Fourth, teachers should give guidance in activities.
The method of practical activities is generally group independent activities. The teacher explained the time and scope of the activity to the students. Teachers participate in activities as bystanders to understand students' thoughts and trends. Teachers can give necessary guidance when students deviate from the direction of investigation and help students solve problems when they encounter them. Students should learn to sort out and analyze data through activities and use data to explain a phenomenon and problem. In order to cultivate students' knowledge and interest in mathematics, practical ability of hands-on operation, investigation and interview, data collection and cooperation spirit, we must give full play to students' dominant position, let students actively participate in activities, and pay attention to students' full participation.
Verb (abbreviation of verb) shows the result of activity.
This is the central link of the activity and the sublimation stage of the activity. On the basis of group discussion and collective evaluation, senior students can organize the results of their own investigation, analysis and discussion into a simple research report, giving students a chance to re-create. Junior students can make an oral report and report the results and findings of their own group investigation and research. Teachers organize the whole class to communicate, show the achievements of each group, put forward some outstanding figures and good practices of each group, and cultivate students' expression ability and the ability to learn from others with an open mind. During the exhibition, students should be given enough space to exchange information and fully express the various gains of this activity.
Sixth, do a good job in activity evaluation.
Evaluation can be divided into three parts: self-evaluation, mutual evaluation and teacher evaluation. In self-evaluation, students should fully display the advantages and characteristics of the activities, and at the same time show the good deeds of team members in the activities in front of the whole class. Then each team member should talk about his gains in the activity and give himself a score. When evaluating each other, we should call a split view to look at others' achievements. Teachers should make a comprehensive evaluation of each group in the spirit of encouragement in order to cultivate students' interest and arouse their enthusiasm and initiative. As long as students make efforts to make progress on the original basis, even small and low progress should be positively evaluated, so that students can see their progress and experience the happiness of success.
Mathematical practice is an effective way to train students to use mathematical knowledge to solve practical problems. The majority of mathematics teachers should actively explore in teaching, so that mathematics knowledge can be better applied to life. ;
