The effects of incentives,instructor motivation and feedback strategies on faculty evaluation response rates in large and small class sizes     

Alicia M. Alvero  Kathleen Mangiapanello  Jennifer Valad 《Assessment & Evaluation in Higher Education》2019,44(4):501-515

Four instructor-led strategies designed to increase faculty teaching response rates were assessed across both small (n?<?50) and large (n?≥?50) class sizes. The interventions included: (a) individual incentives, (b) group incentives, (c) instructor motivation and (d) instructor motivation plus feedback. A comparison group utilizing the standard university strategies was also included in the study. The percentage of answers to open-ended or qualitative questions was measured across groups. The results show that implementing a contingency – whether group or individual – significantly improves the rate at which students complete course evaluation ratings regardless of class size; however, these contingencies, while effective for increasing overall rating response rate, do not promote increased submission rates of qualitative comments. Furthermore, it was found that class GPA did not differ across intervention strategy nor did it influence response rates.  相似文献   

Prediction-Based Student Evaluations of Teaching as an Alternative to Traditional Opinion-Based Evaluations     

Tania Tomes  Astrid Schmulian 《Assessment & Evaluation in Higher Education》2019,44(8):1222-1236

Abstract

The validity of traditional opinion-based student evaluations of teaching (SETs) may be compromised by inattentive responses and low response rates due to evaluation fatigue, and/or by personal response bias. To reduce the impact of evaluation fatigue and personal response bias on SETs, this study explores peer prediction-based SETs as an alternative to opinion-based SETs in a multicultural environment. The results suggest that statistically significant fewer respondents are needed to reach stable average outcomes when peer prediction-based SETs are used than when opinion-based SETs are used. This implies that peer prediction-based SETs could reduce evaluation fatigue, as not all students would need to do each evaluation. The results also report that the peer prediction-based method significantly reduces the bias evident in the opinion-based method, in respect of gender and prior academic performance. However, in respect of the cultural variables, race and home language, bias was identified in the peer prediction-based method, where none was evident in the opinion-based method. These observations, interpreted through the psychology literature on the formulation of perceptions of others, imply that although peer prediction-based SETs may in some instances reduce some personal response bias, it may introduce the perceived bias of others.  相似文献

‘Well I don't feel that’: Schemas,worlds and authentic reading in the classroom     

Marcello Giovanelli  Jessica Mason 《English in Education》2015,49(1):41-55

This article explores reading in the English classroom through a cognitive linguistic lens. In particular, we consider how students' ability to engage with a text, which we term authentic reading, can be facilitated or restricted. We draw on two case studies featuring Year 7 students working with the novel Holes (Sachar 2000), and the short story ‘The man who shouted Teresa' (Calvino 1996) respectively, and argue for the benefits of using cognitive linguistics as a tool for teachers and researchers to ‘think with’ when considering reading in the classroom.  相似文献   

Learning English through actions: a study of mobile-assisted language learning     

Pei-Lin Liu 《Interactive Learning Environments》2015,23(2):158-171

This study investigated the impact of taking photos using mobile phones on the English phrase-learning performance of English as a second-language learners. A total of 116 students enrolled in a college in Central Taiwan participated in this study. The participants were divided randomly into two groups: a control group and an experimental group (EG). The control group was assigned an online phrase-reading activity for the purpose of phrase learning, whereas the EG was instructed to engage in phrase learning by taking photos using their mobile phones. The study primarily investigated the participants' daily encounters with newly acquired phrases through the use of photos taken using mobile phones, which were associated with the sentences they constructed. The results of the study indicated that the students in the EG significantly outperformed the control students on the delayed posttest, and the EG exhibited a significantly higher level of perception toward the phrase-learning activities compared with that of the control group.  相似文献

通过对323名班级心理委员与772名普通学生进行《人际反应指标问卷》测试,发现心理委员在同情关心维度优于普通学生,在其他各方面无显著差异,自变量不同的大学生心理委员人际反应指标存在一定的差异。建议通过将同理心确立为基本的助人价值观,加强人文教育,加强对言语的真诚倾听和非言语信息敏锐性观察的训练、表达训练等方式来提升心理委员同理心能力。  相似文献   

Confirmatory factor analysis of the Sport Emotion Questionnaire in organisational environments     

Rachel Arnold  David Fletcher 《Journal of sports sciences》2015,33(2):169-179

The Sport Emotion Questionnaire (SEQ) (Jones, M. V., Lane, A. M., Bray, S. R., Uphill, M., & Catlin, J. (2005). Development and validation of the SEQ. Journal of Sport and Exercise Psychology, 27, 407–431) was developed and initially validated to assess sport performers’ pre-competitive emotions. The purpose of this study was to test the factor structure of the SEQ in a different environment (viz. organisational) and at a different time point (viz. the past month). A further aim was to examine if the SEQ was invariant across different groups of sport performers. A diverse sample of athletes (n = 1277) completed the questionnaire. Fit indices from confirmatory factor analyses provided partial support for the hypothesised measurement model, with equal or better fit demonstrated than evident in initial validation. The comparative fit index values were above acceptable guidelines for all factors at subscale level. Evidence was also found for the invariance of the SEQ across different groups. Overall, the findings support the reliability and validity of the SEQ as a measure of the emotions experienced by sport performers in an organisational environment during the past month.  相似文献
