Pre- and post-tests were administered to three treatment (136 emotionally handicapped, 8 physically handicapped, and 79 trainable mentally retarded students) and two non-treatment groups (11 emotionally handicapped and 70 non-handicapped students) for purposes of assessing teacher, student, and program centered objectives. Administered or completed by the 21 teachers involved, the instruments employed were: the Student Content Test; the Student Attitude Survey; the General Classroom Behavior Teacher Rating Scale; the Participant Evaluation; and the Participant Narrative Evaluation. The four teacher centered objectives focused on knowing the what, where, how, and why of outdoor teaching; the three student centered objectives focused on increased comprehension of the natural world, self, and others; and the program objectives focused on improvement of student communication skills, understanding re: local environment and environmental problems, social responses, and manipulative/motor skills. Results indicated 7 of the 13 objectives were met and 3 were partially met, while 3 of the program objectives were not directly measurable. Since 3 of the 13 objectives were not measurable, it was concluded that the project was nearly 100% successful. (JC)
