Evaluation of educational strategies for litter control

The Virginia Division of Litter Control's education package entitled Operation Waste Watch (OWW) was evaluated at the first, fourth, and sixth grade level in 19 elementary schools in two southwestern counties in Virginia. Evaluation was provided for the standard curriculum program and for a specially modified behavioral version of the original material. Program evaluation for both curriculum packages was provided immediately before, after, and three months after the implementation of the program and consisted of student achievement testing in terms of knowledge about solid waste management and the assessment of actual student behavior. Specifically, the data was analyzed according to the factorial design: 3 Grade (First, Fourth, Sixth) x 3 Curriculum Condition (Standard, Modified, Control) x 3 Phase (Pre, Post, Follow-up). Significant improvements following the implementation of the educational curriculum occurred only for the student achievement tests. Both programs were found to significantly raise student test performance immediately following presentation of the curriculum materials. The level of student knowledge three months later was also found to statistically surpass baseline performance. However, there was little or no evidence, during Posttesting or Followup, of superior performance by students receiving the modified curriculum program. Supplemental information from the teachers concerning the overall effectiveness of the different curriculum components indicated that while the materials of OWW were needed and generally well constructed, there were severe problems concerning the amount of time needed to adequately teach the different student activities.
