Investigation into the effects of preview on language acquisition

Introduce the content and structure of courseware which multimedia CAI do help previewing physics experiment.

Based on the requirements of the new syllabus and the new idea of compiling teaching materials, this paper presents the strategy to improve the college English teaching efficiency—— guiding students in their preview scientifically.

Preparation is an important factor to make an inorganic chemistry experiment well and the precondition to ensure the experiment being carried out successfully and securely,while the preparation method is the key of preparation effect.

Aiming at the existing defects in the current circuit experiment preparation, it firstly puts forward changing students’attitude to preparation,then guiding students to perform proper preparation according to the different types of experiments, so as to enhance teaching quality of circuit experiments.

The online preview system of the organic chemical experiment can help the students learn the function and usage of the organic chemical experimental instruments, and through the simulation assembly of the experimental devices and instruments, make the students be familiar to reaction process of the organic chemical experiment.

Research in the Preview and Review System for College Physical Experiment;

A statistical investigation were carried out on the previewing notebooks of chemical experiments of chemistry department.
