This study used a multistage mixed-methods analysis to assess the content-related validity (i.e., item validity, sampling validity) and construct-related validity (i.e., substantive validity, structural validity, outcome validity, generalizability) of a teaching evaluation form (TEF) by examining students’ perceptions of characteristics of effective college teachers. Participants were 912 undergraduate and graduate students (10.7% of student body) from various academic majors enrolled at a public university. A sequential mixed-methods analysis led to the development of the CARE-RESPECTED Model of Teaching Evaluation, which represented characteristics that students considered to reflect effective college teaching—comprising four meta-themes (communicator, advocate, responsible, empowering) and nine themes (responsive, enthusiast, student centered, professional, expert, connector, transmitter, ethical, and director). Three of the most prevalent themes were not represented by any of the TEF items; also, endorsement of most themes varied by student attribute (e.g., gender, age), calling into question the content- and construct-related validity of the TEF scores.

A Comparative Analysis of Teacher Effectiveness Ratings by Principals and Teacher Value-Added Measures.'
Policymakers are revolutionizing teacher evaluation by attaching greater stakes to student test scores and observation-based teacher effectiveness measures, but relatively little is known about why they often differ so much. Quantitative analysis of thirty schools suggests that teacher value-added measures and informal principal evaluations are positively, but weakly, correlated. Qualitative analysis suggests that some principals give high value-added teachers low ratings because the teachers exert too little effort and are “lone wolves” who work in isolation and contribute little to the school community. The results suggest that the method of evaluation may not only affect which specific teachers are rewarded in the short term, but shape the qualities of teacher and teaching students experience in the long term.
