Teaching process and design intention

Make a special activity plan in the first class.

First, family talk, the introduction of true feelings

1. Students, each of us will encounter problems that we want to explore. If we can pay attention to collecting information and use relevant information for research, we can solve the problem. You can carry out investigation and research activities, write simple research reports, communicate with people, and cultivate scientists' research quality from an early age.

Please read the text and make clear today's learning requirements. (Text 125)

We read the text just now. Let's discuss it and talk about the requirements of the text.

There are three requirements for students' communication: ① Choose topics that interest them. ② You can cooperate or do your own research. ③ Obtain information by reading newspapers, books and materials, and searching on the Internet. (4) From the collected data, find out the parts that are particularly useful for solving problems, read them several times, and then form your own opinions. Read the following two research reports carefully and discuss how to write them. Then write them separately and communicate with your classmates.

(Design intention) Family talk can stimulate interest, read textbooks with a clear purpose, so that students can eliminate their fear of difficulties and devote themselves enthusiastically.

Please choose a topic that you are most interested in as a group, and use it as the survey topic.

[Design Intention] Let the students choose their own topics of interest, give the initiative of investigation and research to the students themselves, and let the students participate with ease and passion.

Third, make plans and define tasks.

1. Teacher's introduction: Investigation is one of the commonly used methods of scientific inquiry. China's forest resources should be inspected every five years, which is a survey. A census is also a survey. First of all, we should make clear the purpose and object of the investigation and make a plan to stand out from the crowd. The investigation should be truthfully recorded. The survey results should be sorted out and analyzed, and sometimes they should be counted by mathematical methods. Just now, everyone chose the topic that they are most interested in, which is also the question we want to investigate. How should we investigate? First of all, we should make a careful investigation plan. "Everything is done in advance." How to make an investigation plan? Next, we will discuss and design an activity plan on how to investigate the myopia of fifth-grade students.

2. Make clear the object and purpose of the investigation:

Survey object: all students in grade five.

Purpose of investigation:

(1) Understand the myopia of fifth-grade students;

[Design Intention]: Cultivating students' flexibility and openness in analyzing problems will play a good role in promoting students' personality development and creative thinking. By selecting the best from the best, students' interest in using information for research is stimulated.

Reflection after class

In this activity, we designed three links of organizational learning: preparation, process guidance and report evaluation. Let students gain some knowledge, ability, emotional attitude and other gains in the activities. In addition, we gave the final evaluation right to the students in the design of this activity, which also reflected the students' active position in the whole process. In the comprehensive practical activities, with the gradual improvement of students' practical ability, teachers' organizational management role has gradually changed into a cooperative guidance and communication mode. We can express our opinions in their activities, but for the groups who participate in the whole research process, they have more power to win their opinions. While investigating research activities, teachers naturally become their collaborators, giving them ideas and suggestions. Through collective reporting, it provides a good environment for information blending. On the one hand, through the display and exchange of results, it reflects the research value of the subject and has radiation effect; On the other hand, it provides students with opportunities to re-create and learn to appreciate others; On the other hand, the students' practical ability and psychological satisfaction have been greatly improved from careful preparation to presentation. At the same time of self-evaluation and mutual evaluation, we gradually see our own advantages and disadvantages, which can be maintained and revised in future practice. Through investigation activities, students have improved their interview ability, information processing ability and statistical analysis method. More importantly, after this activity, the seeds of the scientific spirit of "doing research with information" were deeply planted in their hearts. To some extent, it improves the quality of students' inquiry. These qualities are beneficial to the lifelong development of students and the future of the country.
