Problems to be noted in the classroom introduction

1, the time should be short

Introduction is a transition link in classroom teaching, the time should be short, generally controlled within 5 minutes, and strive to use the least amount of language, quickly and skillfully shorten the distance between teachers and students, as well as the distance between the students and the materials to focus the attention of the students in the process of searching for knowledge. Avoid a long introduction to occupy the best learning time, so that students produce a shift in attention, and can not achieve the desired goal.

2, clear objectives

Introduction of clear objectives, pointing to focus on preventing all, dilute the focus of the goal, should be selected and the most relevant to the new knowledge, and the teaching of the most important need for the content.

3, level control

Introduction should be based on the degree of difficulty of the knowledge update and the students' existing life experience and knowledge level, in the student's "recent development zone", to guide the "half-baked", resulting in "jumping and picking fruit. "Jump a jump to pick fruit" effect, create a space and situation for students to actively explore, avoid going to the extreme of absurdity.

4, to contextualization

Introduction contextualization, but not absolutely living. Mathematics classroom standards: students in a vivid and concrete situation to understand and recognize mathematical knowledge. Mathematics teaching has long been detached from the actual life of the students, the proposed living mathematics is reasonable. It is favorable to students.

Because of the limitations of students' life experience and mathematical knowledge, coupled with the complexity of life, the introduction should pay attention to the elimination of negative factors, the scenario design should be in line with the actual situation of the students, and can not be noisy.

. p>Classroom introduction methods:

1, self-introduction method

Self-introduction introduction method can be in a relatively short period of time so that teachers and students to understand each other, shorten the distance, but also can be skillfully introduced to the content of the new class, stimulate the students to the thirst for new knowledge.

A successful use of self-introduction method of introduction of the classroom, must be the lecturer well into the new knowledge into the life of the introduction, so it will appear natural, smooth, produce a two birds with one stone effect, rather than hard for the sake of the introduction to the introduction of the introduction to be much better.

2, review the introduction method

At the beginning of each class, teachers usually use the content of the previous lesson as a method of introducing a new lesson. This method is convenient for students to consolidate what they have learned, easy to link the old and new knowledge systematically, and easy for teachers to carry out teaching in a gradual manner.

Review of the introduction of general questions, exercises, retelling, etc., so that students in the "old" on the basis of "into the question" and "know the new". Can also be used to review the way to review, and then introduce a new lesson. This is a review of the previous lesson, but also very natural to introduce a new lesson, is not a good way.

3, pre-study introduction method

This method can cultivate students' ability to learn independently and the spirit of innovation, so that students have a more adequate psychological preparation for the content of the students to verify the students' ability to learn on their own, so that the students have a sense of achievement, so as to develop good learning habits.

Therefore, teachers set up a preview of the content before class, and it is best to set up a few questions, which should be able to allow students to fully expand the problem. Then in the classroom targeted questions, so that students unknowingly into the learning state. However, teachers should pay attention to set up the pre-study questions to be specific, not too much, too difficult.

4, fun introduction method

This is based on the age of the students, the use of children's songs, riddles, paintings, games and other forms of introduction to the new class method. It can stimulate students to learn the hobby, mobilize students to learn actively, to meet their curiosity and desire for knowledge, so that their thinking activities from the state of inhibition into an active state.
