Novel teaching aid for political teaching

Technical Field

The utility model belongs to the technical field of teaching aid technique and specifically relates to a novel teaching aid is used in political teaching.

Background

Many knowledge of politics are invisible, untouchable, abstract, and hollow, if only lean on mr dictation, the student does not have audio-visual impression, and the interest can not be mobilized at all, and the learning effect is not good. The object can help the student to attract the attention of the student in class, arouse great interest of the student, arouse the learning desire of the student and voluntarily enter the learning state. How to change abstract and profound theories into knowledge of being light and easy to understand, impressive and solid in memory and to teach students is a subject in front of teachers. Therefore, in the course of ideological and political course teaching, teachers need to help students understand and learn by showing a large amount of text materials or pictures. Present show board teaching aid is mostly the fixed bolster, and the adjustment is very inconvenient, and the show board is together fixed with the support is many, and the height and the inclination of show board can not carry out corresponding adjustment as required, and the teacher is very inconvenient when carrying out the blackboard writing or posting up teaching material, has influenced teaching efficiency.
