The impact of change facilitator styles (CFS) on elementary teachers' stages of concerns (SoC) about adopting outcome-based education (OBE) in their schools was studied. The group studied was 266 teachers from the Texas Network for Outcome-Based Education. Principal styles are based on the Concerns-Based Adoption Model (CBAM. Styles were determined by the Change Facilitator Style Questionnaire, and teachers' concerns profiles were measured by the Stages of Concern Questionnaire. ANOVA and t tests were conducted to assess the effects of CFS at each of the seven stages of concern. ANOVA assessed teachers' educational level, experience with teaching and OBE, principal gender and type of community related to SoC. Chi-square addressed the relationship among the demographic variables and CFS. With schools as the unit of analysis, significant differences at stages 0,1,2 were found. When teachers were the unit of analysis, significant differences were found at stages 0,1,2, and 3. Concerns of teachers with Initiator style principals were significantly lower at these stages. All teachers demonstrated concerns typical of nonusers, indicating resistance to OBE. Concerns were significantly lower for teachers with master's degree than for bachelor's at stages 0 to 3. Teachers with the least experience with OBE had significantly higher concerns. Chi-square compared change facilitator styles with the demographic variables. The only significant results were more males at the management style than expected. These findings support the CBAMtheory that the initiator style is more effective at impacting SoC and improving success in adopting an innovation. Teacher demographic variables do not affect SoC or CFS. The study indicates problems implementing OBE but suggests effective leadership could impact teachers' concerns.
