A study was conducted to determine if two specific factors had an effect on business teachers' perceptions of barriers to the implementation of a change. The two factors were the type of environment (type of school in which the teacher taught) and whether or not a change was perceived as being new or old. The change was implementation of a competency-based business curriculum. A proportional random sample of secondary, vocational-technical center, and community college business teachers in Florida were asked to respond to a perceived barriers scale and a measure of newness of the competency-based business curriculum. Two-way analysis of variance was used to analyze the data. Results indicated that environment had an effect on the perceptions of barriers. Vocational-technical center teachers saw significantly fewer barriers than did business teachers in the other two types of schools. Findings indicated that the concept of an idea as an innovation made little difference in whether teachers saw barriers to its implementation. No significant interaction effect of the two variables on teachers' perceptions of barriers to implementing the competency-based business education curriculum was found. (YLB)
