Computer-based knowledge of results feedback in different delivery modes: Effects on performance,motivation, and achievement emotions     

《Contemporary educational psychology》2021

Immediate Knowledge of Results (KR) feedback at the task level may motivate test takers by showing that their answers matter. Appealing feedback cues may help to prevent negative emotions in lower performers who receive a higher amount of negative feedback. In this experiment, we varied the presence of KR feedback and the feedback delivery mode in a 1 × 5 between-subjects design (i.e., no feedback vs. text, color, sound, or animation feedback) to investigate effects on learning outcomes and affective-motivational measures. Our sample included 661 fifth and sixth graders who solved two computer-based multiple-choice science tests. First, students worked on an 18-item treatment test (with experimental feedback manipulation). Students repeatedly rated their effort, enjoyment, pride, and boredom during the test, as well as their expectancy of success and attainment value after the test. Subsequently, they worked on a posttest (without feedback) that assessed recall and near-transfer learning. All KR feedback conditions significantly increased recall, but there was no evidence for near-transfer learning. Feedback had a significant, negative effect on attainment value, whereas significant interactions between the feedback conditions and students’ treatment performance revealed that feedback effects on several affective-motivational dimensions (i.e., expectancy of success, enjoyment, pride, and boredom) were performance-dependent. Feedback benefited higher performers’ motivation and affect but showed negative effects on some affective-motivational measures for lower performers. The pattern of results indicated that color/sound/animation feedback may have reduced the effect of performance on emotional feedback perception to some extent. However, none of the feedback conditions improved affective-motivational outcomes independent of students’ performance.  相似文献

Language use in kindergarten science lessons: language production and academic language during a video feedback coaching intervention in kindergarten science lessons     

Astrid Menninga  Marijn van Dijk  Annemie Wetzels  Henderien Steenbeek  Paul van Geert 《Educational Research and Evaluation》2017,23(1-2):26-51

This paper aims to gain insight into language production and academic language of 4- and 5-year-old students and their teachers in the course of a teacher intervention during kindergarten science education. The study is based on videotaped classroom observations, and specifically focuses on the academic language use of students (N_intervention = 18, N_controls = 26) and teachers (N_intervention = 5, N_controls = 5). The results suggest that this general teacher intervention yields interesting changes in language use and production. Patterns of change over time confirm the idiosyncratic and non-linear nature of these changes. Science lessons represent an appropriate context in which to acquaint students with academic language, which can be used as a basis to build upon more sophisticated language skills.  相似文献   

基于BOPPPS和“对分”的混合式课堂实践及成效     

冯瑞玲  董俊  张鸿儒  杨娜  沈宇鹏 《教育教学论坛》2020,(3):3-6

针对目前大学生在课堂上玩手机、走神、课堂气氛沉闷等问题,本研究在课堂讲授的过程中基于BOPPPS有效教学结构,注重“精讲留白”,并引入了“对分”教学理念,将部分课堂时间留给学生进行“隔堂讨论”。学生在听完授课内容后,引导学生在课后内化吸收时以“亮考帮”作业与传统作业形式完成授课内容的复习,为下次课进行“隔堂讨论”准备好“个性化”的讨论素材。经过多次实践,总结了实践过程中需特别注意的问题,收集了学生对这种教学模式的意见。反馈结果表明:采用这种教学模式后,大部分同学均表示加深了对知识点的理解程度,减少了上课玩手机、犯困、走神的时间,因同学提出的问题开拓了自己的思维,激发了学习的兴趣等,使课堂学习进入了良性循环状态。  相似文献   

Strategies for using feedback students bring to higher education   总被引：1，自引：1，他引：1  

Deirdre Burke 《Assessment & Evaluation in Higher Education》2009,34(1):41-50

This article explores strategies for acting on feedback that students bring to their higher education, by exploring student perceptions on the guidance they received from their teachers in school or college. Whilst assessment issues have been the subject of a range of research studies, it is the contention of this article that little research has been undertaken to identify the strategies that students possess for ‘using’ feedback. This small‐scale research study was stimulated by M.R. Weaver’s 2006 Weaver, M.R. 2006. Do students value feedback? Student perceptions of tutors’ written response. Assessment and Evaluation in Higher Education, 31(3): 379–394. [Taylor & Francis Online] [Google Scholar] finding that only a quarter of students had received guidance on how to use feedback prior to university. This exploration identifies the guidance for using feedback that 350 students in Humanities brought to their degree course. Analysis of responses revealed the strategies that students had been introduced to, identifying nine indigenous categories. Whilst almost 40% of these students indicated they had received guidance for using feedback, scrutiny of responses showed that many of these students confused ‘actual feedback’ with ‘guidance on how to use’ feedback. The implications of such starting positions for students and staff are considered: questioning the adequacy of such a foundation for students to be able to make effective use of the feedback they will receive in their degree course, and finally suggesting initiatives by which staff could enable students to get more out of feedback.  相似文献

Training preservice teachers to use evidence-based practices: Effects of coaching with performance feedback on teacher and child outcomes     

《Learning and Instruction》2023

Three-term contingency trials (TCTs) involve planned/naturally occurring antecedents, child's demonstration of target behaviors, and planned/naturally occurring consequences. Positive relationships between teachers' frequent use of TCTs and children's learning were noted in literature. This study aimed to investigate impact of an intervention package including training and coaching with performance feedback on experienced and novice special education preservice teachers' use of TCTs and relationship between teachers' implementation and child outcomes through two single-case experiments using multiple baseline across participants design. Three special education preservice teachers and three children with disabilities participated in each study. Results indicated intervention package was effective in increasing preservice teachers' use of TCTs. Preservice teachers generalized their use and sustained it during maintenance sessions conducted after intervention ended. Furthermore, as frequency and accuracy of preservice teachers' implementation increased, percentage of children's correct responses in relation to target skills improved. Implications for future practice and research are discussed.  相似文献
