Ten criteria for use in assessing the emphasis on environmental education in textbooks and similar resource materials were developed and given to 30 members of the Australian Conservation Foundation Education and Training Committees throughout the country. Each rater applied the criteria to three chapters of a biology textbook "The Web of Life," the Australian adaptation of the Biological Sciences Curriculum Study materials) and three units of the Australian Science Education Project materials (see ED 061 106 and ED 063 167 for two of the units). The results of the rating are presented, and, where appropriate, the maximum deviation from a cumulative reference distribution based on random rating (Kolmogorov-Smirnov one-sample test) is presented. The reliability of each index, and difficulties encountered in its use, are discussed. Copies of the scales, instructions and explanations provided to raters, and the rationale for each criterion are included in an appendix to the report. (AL)
