How to raise effectively review efficiency in short time? This paper puts forward the review method of strengthening rudimentary knowledge and ability training, improving problem solving ability.

Combine the trend of examination of chemical calculations and students\' learning situations about our school, We use two different effective review strategies about chemical calculations in 2 different classes of senior high school, grade three.

An empirical study on effect of soft technology on learning efficiency;

Demonstrative Study on the Factors in Students Mathematics Learning Efficiency;

Differences in Learning Efficiency between Mathematical Disability Students and High Ability Students in High Schools;

This research aims at inquiring into the different background music s influence on the study efficiency to middle school student under the identical condition.

Most students do not realize that self supervision of study has direct influence on their study efficiency.

In the study of Chinese, making full use of the advantages of the transference law will help improve our study efficiency, even obtain the aims of "drawing inferences of other cases from one" and "teaching the students how to fish".

The paper establishes a model on how to evaluate the scheme to improve children s studying efficiency which has been planned the by the educators (the scheme is called briefly efficiency scheme in the following),and how to get the best efficiency scheme with the excellent ability of operation.
