I. teaching material analysis
The role of animals in nature is the first section of chapter 3 in the first volume of the eighth grade of the ecological education edition. This chapter summarizes the role of animals from the height of biosphere, which is consistent with the idea that the first two textbooks highlight man and biosphere. The role of animals in nature indirectly affects human life, laying a foundation for understanding the significance of unit 6 protecting biodiversity. Therefore, this lesson is of great significance for deepening students' understanding that the biosphere is a unified whole. Based on the above analysis, combined with the concept of new curriculum standards, I have determined the following teaching objectives:
Second, the teaching objectives
1 Knowledge objective: (1) Give examples to illustrate the role of animals in maintaining ecological balance, promoting material circulation in ecosystems, helping plants pollinate and spreading seeds. (2) Recognize that animals are important members of the biosphere.
Ability goal: dialectical understanding of the interests of animals and human beings.
Emotional attitude and values: Through the study in this section, I will gradually establish an ecological view, establish environmental awareness, cultivate students' feelings of caring for animals, and establish a sustainable development view.
Third, the establishment of teaching emphasis and difficulty:
1 It shows that it is both important and difficult for animals to maintain ecological balance and promote material circulation in the ecosystem. Recognizing that animals are important members of the biosphere, it is important to cultivate students' love for animals and protect their emotions. It is difficult to learn to understand the beneficial and harmful relationship between animals and humans from a dialectical point of view.
Fourth, teaching methods.
1 This course runs through data analysis and discussion. It mainly uses heuristic dialogue to inspire students' thinking, stimulate their enthusiasm for learning, follow the cognitive law from perceptual knowledge to rational knowledge, and use multimedia modern educational means to guide and help students gradually understand the role of animals in nature through a series of cognitive activities such as observation, thinking, analysis and synthesis.
2 Use the transfer of old and new knowledge to break through difficulties. The concepts of ecological balance and material circulation are abstract. On the basis of reviewing the knowledge about food chain and food web in the first textbook of grade seven, students can understand the relationship between animals' eating and being eaten. The matter and energy in organisms flow from one organism to another along the food chain and food web, which is helpful to understand the concept of material cycle.
Verb (abbreviation of verb) learning method
Through data analysis and discussion, we can discover knowledge, gradually cultivate the habit and ability of autonomous learning, experience the process of knowledge acquisition, appreciate the charm of students' cooperation and taste the fun of inquiry learning. Colleagues have also improved their ability to analyze problems and express them in words.
Sixth, the teaching process.
1 Create scenes to activate thinking
By showing pictures of mascots of Beijing Olympic Games, let students observe the animals represented by each "Fuwa", thus leading to a new lesson.
2. Independent experience and cooperative exploration
(1) By showing the daily behaviors of several groups of animals and the morphological and structural characteristics of plants, students are guided to discuss in groups, and it is concluded that animals can help plants pollinate and spread seeds. At the same time, it is not good to know too much or too little about animals.
(2) Let students read the materials and guide them to think from the perspective of food chain and things, so as to understand the influence of the growth and decline of some animals on other animals. Discuss in groups, and each group can answer questions selectively to create an equal, democratic and harmonious classroom. Under this division, students' thinking is divergent and full of spirituality, and it is easy to agree that animals are important members of the biosphere, so as to learn to understand the pros and cons between animals and humans from a dialectical point of view. Through the above activities, combined with old knowledge, students naturally highlight the difficulty, that is, the role of animals in maintaining ecological balance.
(3) Review the contents of the ecosystem in the first volume of the seventh grade, and show the material cycle through the pictures of the cycle among producers, consumers and decomposers. On the basis of reviewing old knowledge, enter a deeper understanding.
3 Leading knowledge, knowing and unifying.
What else do you know about animals in nature besides the functions we mentioned above? The group cultivates students' team spirit through competitions. This leads to our love and protection of animals.
4 summary and promotion, make the finishing point
Through the analysis of the role of animals in the animal kingdom, it is not difficult to see that the biosphere is an interactive and mutually restrictive whole that agrees to make up lessons. Everyone has a responsibility to protect the biosphere.
5 practice
Homework: According to the actual situation, make a handwritten newspaper to protect animals.
