Slice Up - The Thin Slices Technique: Application to classroom instruction and analysis of judgement processes
Final Report Abstract
The Slice-Up project investigated a highly economical method to analyze teaching quality that has thus far rarely been used in instructional research. In the thin slice technique, untrained raters assess dimensions of teaching quality on the basis of very short video clips. The project used data from existing video studies to determine the accuracy of such judgments, to investigate the cognitive processes leading to the judgment and to derive practical recommendations for the successful application of the technique. The work program included secondary analyses of existing video studies, (quasi-)experimental studies and metaanalyses. The results showed that teaching clips of only 30 seconds in length are sufficient to obtain a sufficiently accurate judgment of the teaching quality in this class and that these judgments are made on the basis of a rapid, intuitive form of information processing. The quality ratings obtained by the TST show high reliability and correlate with quality ratings of trained raters who evaluated the entire lesson. Accuracy increases with the number of raters. Two longitudinal studies in which student outcomes were predicted by the teaching quality as measured by the TST brought inconsistent results. In summary, the TST can be recommended as a quick and efficient screening tool for teaching quality, but it cannot replace a detailed analysis of teaching.
