The Comparison And Study Of Exercises Of The New High School Chemistry Textbook

The Exercise is an important part of the senior school chemistry textbook. Exercise will not only help students to consolidate, skilled, live basic knowledge to enhance their memory and understanding of chemical knowledge; but which is an important carrier for students’ learning ability. New Curriculum for all versions of the exercises with a chemistry textbook, the researchers know which version to better reflect the concept of the new curriculum standards, which version of the exercises can really change with the outline, which version of the number of exercises, the difficulty with more Good hierarchy and discrimination, the paper selected based on current "Curriculum Standards" adopted by the preparation and validation of three new high school textbooks:People’s Education Press (Song Xinqi editor), Jiangsu Education Press (Wang Zuhao editor), Shandong Science and Technology Press (Lei editor) for the study.This paper from a number of exercises, the difficulty level of material and other aspects of the three versions of the textbook exercises were analyzed and compared.By comparison of the three versions of textbooks exercises, the following conclusions:the number of the exercises, the PEP larger number of textbook exercises, a total of473; for Jiangsu small number of exercises in the textbook, for a total of352; Luke version of the number of textbook exercises the least, for a total of329. Type in the exercises, the three versions of the exercises have the following materials:①The traditional format (such as:multiple choice, filling, quiz questions) still dominant;②open questions (such as:practical exercises, experimental design) increased proportion;③setting exercises reflect the comprehensive, diversity and flexibility. Material in the exercises, the three versions of textbook exercises in class exercises related to the proportion of living is not high. Difficulty in a comprehensive exercise, the exercises for Jiangsu in the "background","reasoning" and "practical exercise" four factors were higher than PEP and the Luke version, and in the "inquiry" of the lower in the PEP. The overall situation from a graphical point of view, the three versions of textbooks are focused on the "reasoning" and of "practical exercise" is more lightly. Exercise above the level in the three versions of the materials in the text after the exercises and the difficulty of the exercises are much the same. Exercise of these materials through the analysis of three versions, for the majority of classroom teachers in order to better grasp the material heavy and difficult to provide some useful information.
