The biggest feature of heuristic exploration method is to stimulate children's interest, arouse their initiative and enthusiasm in learning to the maximum extent, and guide children to explore and acquire new knowledge independently through positive thinking. The heuristic exploration method of children's mathematics teaching is mainly to mobilize children's active exploration activities through teachers' enlightening questions. There are many kinds of problems, which are divided into positive problems and negative problems.
When the children in the small class compared the number of objects between the two groups, the teacher asked, "Which is more? Which one is less? " "Still as much", this is an affirmative question; When the big class knows the relationship between three adjacent numbers, the teacher can directly ask Liu 6' s neighbors (good friends). You can also ask, "Whose neighbors are 6 and 8?" ? "This is a negative question.
Problems can also be divided into general problems and specific problems. A general question means that the question itself is a general question, and the question does not contain any hints. Specific questioning means that the question itself contains hints about the way to answer the question, but the degree of hints can be different. For example, the big class knows a cube, and l asks the children to compare a plane square with a cube (each face of the cube is as big as a plane square). The teacher can ask the question, "What's the difference between a square and a cube?" (general question), this question contains a wide range of contents. Www.jy 135.com may give various answers to this question. Individual children may say that a cube has many sides, and the teacher may further ask, "How many sides does a cube have?" (specific questions),
This question only points to the number of faces that make up a cube, so it is more specific than the general question. When counting cubes, some children will turn the cubes over and ask these children who really have difficulties: "Are you counting from different directions?" Even tell the child directly, "How many faces have you counted from up, down, left, right, front and back?" This is a specific problem, and there are hints to solve it. These two specific questions are different from different directions and directly tell them that the suggestibility is different. The latter has almost no suggestibility, so children are required to make different thinking efforts in exploration.
Asking questions is also a way of asking questions, which is often used to ask children to prove their answers or state reasons. For example, after the children in the middle and large classes make a correct judgment on logarithmic conservation or shape conservation, the teacher further forces them to ask: "Why do they have different things, different colors, different postures, or the same amount?" Or "Why are they all triangular in size and color?" Wait a minute. Asking questions can promote children to further explore relevant mathematical knowledge and cultivate their initial logical thinking ability.
When using heuristic exploration method, we often pay attention to the following aspects:
1, heuristic exploration method is suitable for classes of all ages and should be implemented throughout the teaching process.
2. Heuristic exploration method should be combined with operation method.
3. Teachers should be good at asking questions. Only by asking questions to the point can we enlighten the key points and let the questions guide the children's thinking and explore the direction.
Children should be allowed to explore problems independently under the inspiration of teachers. After the teacher asks questions, we should encourage each child to think independently about the answers to the questions and let each child do his best intellectually. Under this premise, we should also create conditions to carry out * * * exploration activities among children.
5, using heuristic exploration method, facing the whole, individual treatment.
Of course, in the process of cultivating children's inquiry consciousness, we should also pay attention to the following points: (1) homework materials should be changeable; Explore the content of the theme with imagination; Teachers' problem setting should have multiple solutions.
