First, the vivid introduction of multimedia courseware is conducive to focusing children's attention and stimulating their interest in learning.
Bruner, a contemporary cognitive psychologist, said: "The best learning motivation is to be interested in the learning materials themselves." "Interest is the best teacher." Multimedia teaching comprehensively uses the effects of shape, color, sound and light to create various vivid learning and teaching situations, which can greatly stimulate children's interest in learning and make them unconsciously engage in teaching activities. For a long time, I have found that some children with poor discipline can quickly calm down and watch multimedia courseware during teaching, which is particularly serious.
At the beginning of the activity of "Saving Laziness with Wisdom", I showed the courseware, taking a scene about lazy wolves chasing by the river in the children's favorite cartoon "Happy and Big Big Wolf" as the background to stimulate children's interest in this activity.
Because children in small classes are limited by age, they don't pay attention to things for a long time. The teacher telling stories is a relatively quiet activity. If monotonous preaching is adopted, children are not only difficult to understand, but also prone to fatigue, which ultimately affects the educational effect. The participation of courseware is helpful to solve this problem. Thinking in early childhood is mainly carried out with the help of concrete images, not with the help of conceptual judgment and reasoning. So I will tell this story in the form of multimedia animation. Multimedia courseware can express more abstract truth or requirements with pictures. It is very concrete, not only with bright colors and vivid images, but also with sweet music and infectious sound. It can be said that it is a combination of shape, sound and color. Children can listen, watch, entertain and think, which can easily arouse students' interest in learning, thus stimulating their enthusiasm for learning.
Second, using multimedia courseware to skillfully set up game situations is conducive to encouraging children to explore new knowledge.
The famous educator Chen Heqin once said: "Games are children's lives". Children in small classes especially like games, and mathematics is relatively abstract and boring because of its subject characteristics. If we integrate mathematics knowledge into games and let children play middle school, we can not only meet the needs of children's games, but also achieve the purpose of mathematics teaching. Using games in multimedia courseware can also organically combine entertainment and education.
I designed a game to exercise children in activities, so that children can develop their intelligence in the game, experience the joy of success and change their interest in pursuing success again. The outline puts forward: "Guide children to be interested in the phenomena of number, shape, quantity, time and space in the surrounding environment, construct a preliminary concept of number, and learn to solve some simple problems in life and games with simple mathematical methods." In the courseware, I set "shape link" as the first level. There are four beautiful homes on the screen, which are the homes of chickens, rabbits, dogs and kittens. Every home is marked with their favorite shape. Chickens like to make friends with triangles, rabbits like to make friends with circles, dogs like to make friends with squares and kittens like to make friends with hearts. When the mouse clicks on a shape, ask the children to help it find a friend and connect it to the corresponding home. If it finds the right one, it will make a cheerful cry of small animals. If you make a mistake, the shape will automatically return to its original position (these are all preset paths in the courseware). ) At the same time, it sounds "Please, please think again". Using computers to make various lively and lovely animals, with colorful backgrounds and lively and pleasant sounds, the whole process is clear, vivid, vivid and lifelike, which effectively stimulates children's hearing, audio-visual and makes them have a strong interest in learning and a strong desire to explore, laying a good foundation for completing activities.
Children in small classes are interested in bright colors, so in the second level, I showed four identical houses, but the colors were different, including blue, red, green and yellow. The topic of this level is called color touch, which is to let children see what color house they have in their hands, and then touch the house with the same color as you on TV. If it is right, click the music "Congratulations, you are right, you are great", if it is wrong, click the music "Keep working hard, come on, come on". In this way, children's participation in this mathematical activity is obviously improved, and their learning changes from passive to active, and they gradually master more abstract and boring mathematical knowledge in the game. It is more direct and convenient to praise children with sound effects in multimedia, so that children can have interest, emotional reserve, quick thinking and self-confidence in activities than to fiddle with pictures in traditional teaching and then wait for the teacher to check the effect.
Children have a strong desire for self-expression, and when the performance is successful, it will arouse the desire for re-expression. As the organizer of teaching activities, I use multimedia courseware to provide rich perceptual materials for children, create diverse learning situations that can stimulate new strangeness, truly give children autonomy, let children break the shackles of conventional thinking, and actively think about problems from different ways and angles with their own wisdom and ability, actively explore and creatively solve problems. According to children's cognitive rules, consciously use multimedia courseware to create problem situations. The third level is to combine one or two levels to let children know how to match things, both colors and shapes, and to stimulate their desire for expression with "wisdom test"!
Thirdly, the dynamic demonstration of multimedia courseware is used to realize human-computer interaction.
Multimedia courseware has the best audio-visual effect because of its intuitive and vivid characteristics. It provides many possibilities, which are often beyond our ordinary teaching methods. It will make the silent teaching materials vivid, make the classroom vivid, introduce students into the unique situation created by teaching, and make children interested in activity learning through direct audio-visual sensory effects. At the end of Saving Laziness with Wisdom, the dynamic image of lazy crying in the slowly opened door and the combination of door opening sound and lazy crying sound are designed, which makes the picture more vivid, concrete, intuitive and dynamic and strongly attracts children. Then I showed a lazy and happy smiling face, which brought the whole activity to a successful conclusion. The children saw that they had saved laziness with everyone's efforts, and everyone was very happy, which effectively realized the effect of human-computer interaction.
Through teaching practice and children's performance, I deeply realized the benefits of using multimedia courseware to assist mathematics teaching. It can make children have a strong interest in boring and abstract mathematical content, make children actively think, calculate, compare and discover the laws between perceived things, phenomena and mathematical concepts, develop children's creative thinking, make children learn actively, easily and flexibly, and bring unlimited fun to children.
