Slice Up - The Thin Slices Technique: Application to classroom instruction and analysis of judgement processes

该项目的目标是研究一个高度经济的测量方法的适用性-这还没有被广泛用于教学研究-教学质量变量的分析。薄片技术（英语：Thin Slices technique，简称TST）是一种在人格研究中发展起来的方法，法官根据非常短的视频剪辑（最长5分钟）来评估其他人。TST在不同领域的应用表明，它是可能的，以可靠的方式评估各种人或互动变量，虽然法官只能获得非常有限的信息，因此，只能形成第一印象。跨各种域（例如，社会心理学、心理治疗、组织研究、体育运动），这些快速判断显示出高度的可靠性和实际相关性，例如通过预测未来的事件或行为。迄今为止，TST几乎没有在教育背景下使用。这是令人惊讶的事实，特别是在教学研究中，有一个客观的高需求，但在同一时间经济的方法来分析教学过程中的课堂。本研究拟探讨以下相关研究问题：（1）TST能否应用于评估与学习相关的教学过程，以及TST评估的准确性如何？(2)TST的判断基于哪些认知过程，哪些因素影响评级？该研究计划包括对现有视频研究的重新分析，实验和准实验研究以及荟萃分析。如果TST的课堂教学的分析成功的应用，这种方法可以帮助进行研究的教学变量的影响与迄今为止常见的视频研究中的大样本，也可以找到实际用途，例如在评估或专业发展课程的教师。

The goal of the proposed project is to examine the applicability of a highly economical measurement approach – which has not yet been much used in instructional research – to the analysis of instructional quality variables. The thin slices technique (TST) is a method developed in personality research in which judges evaluate other persons on the basis of very short video clips (maximum five minutes). The application of the TST in diverse domains shows that it is possible to assess various person or interaction variables in a reliable manner although the judges have access to only very limited information and thus, only a first impression can be formed. Across various domains (e.g., social psychology, psychotherapy, organizational research, sports) these fast judgements show high reliability and practical relevance, for instance by predicting future events or behaviors. To date, the TST has hardly been used in educational contexts. This is surprising given the fact that especially in instructional research there is a high demand for objective, but at the same time economical methods to analyze instructional processes in the classroom. Several studies are planned to examine the following related research questions: (1) Can the TST be applied to assess those instructional processes that are relevant for learning and how accurate are the ratings gained from TST? (2) On which cognitive processes are the TST judgements based and which factors influence the ratings? The research program includes re-analyses from existing video studies, experimental and quasi-experimental studies, and a meta-analysis. If the application of the TST to the analysis of classroom instruction succeeds, this method could help to carry out research on the effects of instructional variables with larger samples as hitherto common in video studies and could also find practical use for example in evaluations or professional development courses for teachers.
