The influence of background variables on both leadership and efficacy is also analyzed. A sequential mixed methods approach was used in this study. The survey sample was comprised of teachers in the elementary divisions of schools from the nine international school regional associations. Teacher participation was obtained through an email containing an online survey link. Following the analysis of survey responses (N=356), in-depth interviews (N=17) were conducted. Reliability for the instructional leadership scale was found to be .94 (coefficient alpha) and .69 for the personal science teaching efficacy (PSTE) scale. The results show a significant correlation between elementary school teachers' perceptions of principal instructional leadership and their PSTE levels, with the most significant correlation that between the study of a science-related major or minor at college and higher PSTE scores. Strong correlations were also found between PSTE levels and having principals who discussed goals at faculty meetings, participated in science curricular review, supported recognition of student progress, encouraged new skills and concepts, discussed student progress with faculty, and used assessments to see science progress towards easily understood goals. PSTE levels were also higher in schools where principals had grade or school level science coordinators in place and where they supported the use of science kits.en-USElementary SchoolInstructional LeadershipPrincipalsScienceSelf EfficacyTeachersEducational Policy and AdministrationThesis or Dissertation
