Abstract
In research on teaching and teachers, there is a need for valid and economic methods of assessing teaching quality. One approach to such assessment of teaching quality is the so-called thin slices method of video observations—short sequences judged by briefly trained raters. Until now, this method has been used on cross-sectional data only, and not in studies evaluating professional development programs of teachers. In this study, ratings of 41 teacher trainees were cross-validated with student judgments (N = 806) of the same observed lessons in the context of a mindfulness intervention study. For the aspects Disturbances, Time Efficiency, and Student Support, the agreement of students’ and external raters’ ratings was established, underscoring the criterion validity. Additionally, ratings based on the thin slices method were sensitive enough to detect general time effects during teacher training and training effects of an intervention for teachers both on classroom disturbances.
期刊介绍:
Studies in Educational Evaluation publishes original reports of evaluation studies. Four types of articles are published by the journal: (a) Empirical evaluation studies representing evaluation practice in educational systems around the world; (b) Theoretical reflections and empirical studies related to issues involved in the evaluation of educational programs, educational institutions, educational personnel and student assessment; (c) Articles summarizing the state-of-the-art concerning specific topics in evaluation in general or in a particular country or group of countries; (d) Book reviews and brief abstracts of evaluation studies.
