First, teaching material analysis:

1. Teaching content: Fish are our friends. In children's world, fish is their most familiar and favorite object of expression. Through watching movies, playing games and doing things, students are guided to try to draw and make colorful tropical fish with colored pens, Chinese painting pigments, oil pastels, colored paper and other materials. Encourage students to boldly express distinctive fish shapes, thus promoting the formation and development of students' personality.

2. Teaching emphases and difficulties:

The focus of teaching is to guide students to appreciate and observe all kinds of fish, feel the shape and color of fish, feel the beauty of fish, draw and decorate fish in their favorite way, so as to cultivate students' love for nature.

Difficulties in teaching can be expressed by painting, tearing paper or cutting paper, and attention should be paid to color matching to expand students' ability to express fish.

Second, the analysis of learning situation:

The fourth-grade students basically master art tools and materials, and have a certain grasp of the use of different materials and tools. They will use lines and color blocks to express what they know. Most children are only children now. They have a wide range of ways to receive information, active thinking, rich imagination and strange associations. They are self-centered and like to express their pictures freely according to their own ideas. Strong curiosity, love to express themselves, but poor hands-on ability, can only use simple tools and painting materials to express their ideas naively. The lesson of "painting fish in ink" is to let them express their ideas freely in a relaxed and happy atmosphere, which is in line with the characteristics of students' development.

Third, the teaching objectives:

According to the understanding of the textbook and the students' situation, the teaching objectives of this course are determined:

Cognitive field: guide students to appreciate the beautiful underwater world and let them express tropical fish with different methods and materials.

Operation field: Learn to draw fish by cutting, pasting, painting and collage, and train students' practical ability.

Emotional field: let students be influenced by beauty in the process of appreciation, know how to cherish nature and care for life in hands-on production, enhance students' love for nature and sense of responsibility for protecting nature, and stimulate students' awareness of human ecological protection.

Fourth, the analysis of teaching methods:

1, watch movies to stimulate interest in learning. 2. Appreciate the pictures and know the shape of the fish.

3. The game of making fish enlivens the classroom atmosphere. 4. Demonstrate the drawing of fish.

5. Create situations and stimulate creative potential.

Five, teaching process design, teaching process design.

1, introducing animation to stimulate aesthetic expectation.

? Students, have you ever seen the sea? Yes, the blue sea is endless, but when the waves roll on the sea, the bottom of the sea is another scene. Do you want to travel around the beautiful and magical underwater world with your teacher? The teacher's attractive language firmly grasped the students' curiosity and timely played the wonderful clips in the movie Underwater World. Attract students' vision and hearing, let them enter the situation, let students miss and yearn for it. At the same time, it also stimulates students' interest in learning. In the process of appreciation, let them observe the underwater world by themselves, which is intuitive and vivid. After enjoying it, let the students talk about the protagonist in the sea. The students scrambled to push the classroom atmosphere to the first climax. Then it reveals today's learning theme "painting fish with colored ink", from films to topics, from students' interest to arousing students' desire for knowledge, following students' psychological characteristics, keeping students' interest in painting and expressing objects.

2. Observe and perceive the shape of fish.

Show a picture of different shapes of marine fish with courseware and ask which shapes are combined. Let the students observe with questions in the process of appreciation, and then talk about it with their own observations. When the mouse moves, the contours of different geometric shapes will change color, so although the pictures are rich in color, students can find out what shapes these fish are made of. The different geometric shapes of fish are repeatedly emphasized here, so that students can intuitively master the method of drawing fish. Summarize into various simple geometric shapes, combine them, cut or decorate them slightly, and put on beautiful flowers and clothes, and you can create many beautiful marine fish. Children's modeling methods are vivid, distorted, exaggerated and even abstract; Let students understand the structure, and with the unique nature of children, the painting language will be more vivid and expressive.

3. Play with fish and enjoy fish, and walk into the world of fish.

Children have a desire to express themselves. Let students express fish in body language, which not only enlivens the classroom atmosphere, but also lays the foundation for students to express fish more vividly in the following process. Then the courseware shows students how to enjoy the beautiful pictures of a large number of marine fish in music. I made it specially with courseware. Methods The picture appreciation setting was gradually changed from black and white to color, so that students could learn to identify colors through phenomena invisibly, which stimulated their creative desire and activated the original students' painting methods on the basis of a lot of perception. What method would you use to represent fish? Draw with crayons and oil pastels; Cut and paste with colored paper. ? According to the students' answers, I summed it up: coloring and painting, cutting and pasting colored paper. Give a demonstration and supplementary explanation of the summarized methods, for example, you can also use comprehensive materials such as leaves to let them further understand and master what they have learned today. Our teaching should first consider children's accumulation of life experience, and adopt the above methods according to the characteristics of children's acceptance skills.

4. Draw a fish and cut it, and start the creative process.

Ask the students to look at the pictures of the underwater world. How are you going to express your fish? What shape fish do you want to represent? What pattern clothes it wears are three requirements for creation. Then let the students use the beautiful water plants and corals distributed by the teacher to paste their beautiful fish on the big paper. Students can also draw directly. In this process, we constantly play a large number of pictures of marine fish, and appreciate the pictures circularly, so that students can create in a pleasant artistic atmosphere, which has certain reference significance, broadens their horizons, activates their thinking, and enables them to be influenced by beauty invisibly. In the process of making, students are encouraged to combine various methods to draw fish with different colors and shapes from others, and start a competition, thus encouraging students to innovate and improving their creative ability.

Sixth, classroom evaluation.

1, comment on fish and analyze fish, and share creative happiness.

Teachers and students appreciate the beautiful seascape created by students on the blackboard. Let the students evaluate each other first. What kind of fish do you think is the most beautiful? Guide students to evaluate from the following aspects: whether the collocation of colors is appropriate, whether the change of modeling is vivid, and whether the use of materials is unique. Then teachers and students evaluate each other, teachers affirm students' evaluation, excellent works are praised in time, and unsatisfactory works are encouraged, reminding us to pay attention to overcoming these shortcomings and avoid weaknesses in future homework. A small work is a small soul's exploration of the world. Its unique imagination, bold conception, free technique and unrestrained color are the most touching and wonderful values of children's works.

2. Expansion and extension

Teacher's talk: Students, just now we enjoyed the beauty of the underwater world with our eyes and created the beauty of the underwater world with our hands. After going down, please find out where there are fish patterns around us and how they are expressed. Find out more about fish on the Internet.

Finally, the teacher summed up the dialogue: the underwater world is very beautiful and is a treasure given to us by nature. We have greater responsibility to protect it and feel its beauty at the same time. How can we protect it? Please collect this information after class and discuss it together.

In this way, students can know how to cherish nature and care for living things, enhance their love for nature and sense of responsibility for protecting nature, and thus stimulate their knowledge of human ecological protection.
