PowerPoint slide provision and student performance: the moderating roles of self-efficacy and gender

Research on the pedagogical value of providing students with PowerPoint (PPT) slide handouts has produced mixed results. One reason for the inconsistent findings may be that most studies in this stream of research have neglected to examine individual differences. In the current study, we aimed to advance research on the pedagogical value of providing students with access to PPT slide handouts by examining whether self-efficacy and gender influence the effect of PPT slide provision on academic performance. We found no evidence to suggest that the provision of slide handouts has broad, unconditional pedagogical value. Instead, we found that both self-efficacy and gender moderated the extent to which the availability of the handouts enhanced or hindered students’ performance. As predicted, both students high on self-efficacy and males performed significantly better when they were provided with handouts. Conversely, students low on self-efficacy performed significantly worse when the handouts were provided. Female students also trended toward lower performance when the handouts were provided. Additionally, we found that students who were provided with PPT handouts perceived their instructor as more effective, and that this relation was mediated by students’ feeling of preparation. Finally, students also considered the provision of PPT handouts more valuable to their learning and course performance than one-to-one interactions with the professor. Implications for research and practice are discussed.  相似文献

Perceptions of the school self-evaluation process: the case of Abu Dhabi     

Rida Blaik Hourani  David Litz 《School Leadership & Management》2016,36(3):247-270

The Abu Dhabi Education Council (ADEC) has initiated educational change and school improvements. As part of the school reform agenda, ADEC has introduced school self-evaluation-Irtiqaa (SSE-Irtiqaa). This research probes the effectiveness of school administrators (SAs), including principals, vice principals, academic principals, and heads of faculty, and their perceptions of the implications and implementation of SSE-Irtiqaa. The study also intends to improve school quality and help benchmark Abu Dhabi public schools with international academic standards, by tracing challenges faced during the SSE-Irtiqaa process. Public SAs are the participants of this study. This research is an exploratory case study that employed a qualitative research tool. Semi-structured individual interviews were conducted with 14 administrators representing 6 public schools in Abu Dhabi. Findings and recommendations shed light on the areas and paths of development required to facilitate and improve the SSE-Irtiqaa process.  相似文献   

Li1xNaxV3O8电极在硫酸锂-水-乙醇体系中的电化学性能     

袁安保  宋维相 《上海大学学报(英文版)》2007,11(4):411-414

A series of Lil-xNaxV3O8 materials was prepared by solution reaction followed by calcination method and their electrochemical performances in 2 M LieSOa-water-ethanol solution as negative electrodes for aqueous electrolyte lithium ion battery were studied and compared each other. X-ray diffraction analysis revealed that partially substituting sodium for lithium in LiV3Os could increase the interlayer distances of （100） plane. Cyclic voltammetric experiments have demonstrated that the Li^＋ insertion and extraction kinetics of Li0.7Na0.3V3O8 is superior to that of LiV3O8. Charge/discharge results showed that the discharge specific capacity of Li0.7Na0.3V3O8 electrode is higher than that of LiV3O8 electrode.  相似文献

School Management Teams’ Instructional Leadership Role in Closing the Achievement Gap in Impoverished Schools     

Raj Mestry 《Africa Education Review》2019,16(6):94-110

Abstract

Although the South African government has made numerous strides in addressing equity and social justice in education, significant inequalities still exist in learner performance, especially in many impoverished schools. One of the reasons cited for poor learner achievement is the ineffective leadership role of school management teams (SMTs). This article reports on a study that explored the instructional leadership role of SMTs of public schools with the view to closing the achievement gap in poor performing schools. To gain better insights into the SMTs’ realities and experiences of their work as curriculum leaders, qualitative research located within the interpretivist paradigm was undertaken. The findings revealed that SMTs of impoverished schools exhibit consistently low to moderate instructional leadership competencies which ultimately affect student learning. In order to close the achievement gap in poor performing schools, SMTs should play a more pronounced instructional leadership role by leading and managing core curriculum matters and educational resources effectively and efficiently.  相似文献
