Abstract:

The use of student evaluation of teaching (SET) remains as a controversial topic due to various issues associated with it (e.g. lack of established reliability and validity, poor predictors of student learning, prone to biases and errors). Though this might be the case, SETs are still considered as essential tools in providing feedback on teaching effectiveness and facilitating decisions on the professional development of teachers. This study was then aimed at developing a reliable, valid, and functional Teachers’ Behavior Inventory (TBI) for the Basic Education Department (BED) following the standards set by the government, accrediting bodies, and educational organizations. Different statistical analyses were used to establish the internal consistency, content validity, factorial purity, and convergent validity of the instrument. The results show that the items are strongly interrelated and are deemed reasonably relevant and clear by seasoned teachers. The instrument also yielded a strong correlation with a US-based teacher evaluation tool. However, adjustments were made in the factorial validity of the TBI in which a three-factor model was considered more appropriate than a two-factor model. Research implications and recommendations are discussed.
