摘要

Policy makers and school administrators have sometimes relied on very indirect indicators of instructional effectiveness (e.g., teacher experience, student outcomes, etc.). Classroom observation protocols are a more direct, and potentially more valid, measure of instructional effectiveness. However, some observational measures may be impractical for field use and many observational protocols lack sufficient evidence of psychometric properties such as standardization, validity, and reliability. The Observation of Learning Environments (OLE) is a classroom observation protocol intended to measure on-line mathematics classroom instruction. This study investigated the score reliability, construct validity, and inter-rater agreement of the OLE and found that while score reliability and inter-rater reliability were strong, evidence supporting the construct validity of this measure was limited. Suggestions for improving construct validity evidence were offered.
