The increasing popularity of including environmental topics and issues in school curricula has created a need for effective environmental education teachers. One way to evaluate teacher effectiveness is through teacher efficacy, a belief measure that evaluates a teacher's perception that he/she can teach effectively. Research suggests that teachers' instructional decisions are influenced by their beliefs, which are framed by their personal experiences. Because teacher efficacy is content specific, the purpose of this study was to develop a survey, the Environmental Education Teacher Efficacy Belief Instrument (EETEBI), to measure the teacher efficacy beliefs of preservice teachers as they relate to environmental education teaching strategies and outcomes.
