Abstract

This study is attempted to investigate the analysis and the evaluation of achievement of student learning of envirnomental concepts in chemistry of senior high school. As the results of content analysis, there are 692 concepts in all of the chemical textbooks of high school. The results are:
  1. The analysis of environmental concepts of teaching materials in chemistry
    1. The most environmental concepts are distributed in the second book of basic physicochemisty, and the first and the fourth books of chemistry.
    2. Accordin. to Q-technique and the analysis of concept maps, all of the environmental concepts are categorized into 4 groups of concepts: energy, ecosystem balance, air and air pollution and water and water pollution.
    3. From these four categories, we can make four concept maps.
    4. It is better discussed about the kinds, causes, mechanisms, and effects in chemistry than those in the other text book (biology, earth science, civils and geography)
    5. The enviromental concepts in chemistry are about mainly inorganic resources and the preventation the public damges, as in a series of air and air pollution, water and water pollution, energy, and ecosystem balance.
  2. The achievements of student learning of environmental concepts in chemistry.
    1. The concept maps of environmental concepts were used as a base to develop the test tool. In addition, the concept maps can also be used as a base to design teaching activities. As combined with IRS analysis, it can help us to understand the processes of concept formation.
    2. According to the pass rates of answers, the 10 grade got 4%, then the 11,31%; the 12,61%. The results showed the higher the grades the higher the pass rates.
    3. According to the IRS analysis, there are apparent good knowledge construrtion, as a series in air and air pollution, water and water pollution, energy, and ecosystem balance.
    4. As to the IRS analysis, there is a better hierarchy in air and air pollution, then, in energy, ecosystem balance, and water and water pollution.
    5. The current physics textbooks, there is no any environmental teaching materials.
