This supplementary report presents the final evaluation conducted to determine the effectiveness of 34 environmental curriculum units for grades K-6 that were developed by the Center for the Development of Environmental Curriculum. A preliminary evaluation consisting of in-class use and review was conducted in 1973. The final evaluation based on criteria established by ESEA IV included 54 teachers and 15 nonteachers who reviewed the environmental curriculum units. Teachers reviewing the material were provided with a packet pertinent to their grade level. All nonteachers received all 34 units. Each reviewer completed one questionnaire for each unit which consisted of 20 questions to be rated 1 (Strongly Agree) through 7 (Strongly Disagree). Based on the results, 31 units or 91.2 percent of the units successfully met all criteria. This supplementary report also contains 41 appendixes that include a further breakdown of the evaluation and other related materials. (Author/TK)
