The false dichotomy of message desirability in third-person effect scholarship     

David R Dewberry 《Qualitative Research Reports in Communication》2019,20(1):1-8

Meta-reviews of the third-person effect literature explain that scholars have assumed that certain messages are desirable or undesirable. In response, this study examines messages that vary in their social desirability so that we can better understand the specific characteristics of socially (un)desirable messages, how people account for changes in their perceptions of a message’s desirability, and the resulting behaviors from those perceptions.  相似文献   

Professional development on fostering students’ academic language proficiency across the curriculum—A meta-analysis of its impact on teachers’ cognition and teaching practices     

《Teaching and Teacher Education》2020

This meta-analysis aggregates effects from 10 studies evaluating professional development interventions aimed at qualifying in-service teachers to support their students in mastering academic language skills while teaching their respective subject areas. The analysis of a subset of studies revealed a small non-significant weighted training effect on teachers’ cognition (g’ = 0.21, SE = 0.14). An effect aggregation including all studies (with 650 teachers) revealed a medium to large weighted overall effect on teachers’ classroom practices (g’ = 0.71, SE = 0.16). Methodological variables moderated the effect magnitude. Nevertheless, the results suggest professional development is beneficial for improving teachers’ practice.  相似文献

Critical features of professional development programs: Comparing content focus and impact of two large-scale programs     

《Teaching and Teacher Education》2018

By comparing two large-scale professional development programs' content and impact on student achievement, we contribute to research on critical features of high quality professional development, especially content focus. Even though the programs are conducted in the same context and are highly similar if characterized according to established research frameworks, our results suggest that they differ in their impact on student achievement. We therefore develop an analytical framework that allow us to characterize the programs’ content and delivery in detail. Through this approach, we identify important differences between the programs that provide explanatory value in discussing reasons for their differing impacts.  相似文献   

Negotiating the teaching of history in times of curriculum reform: the narrative accounts of four Australian primary teachers     

Paul Reitano  Satine Winter 《Curriculum Journal》2017,28(3):403-420

This research investigates the understandings of four teachers who teach history in primary and early childhood settings. Data were gathered from participants through semi-structured interviews. The participants were experienced teachers who were in the process of curriculum change – from teachers of studies of society and environment to teachers of history, under the auspices of the Australian Curriculum: History. The focus of the study was on their understandings of content knowledge and the pedagogies involved in classroom teaching, using a pedagogical framework, which sought to identify and categorise the nature of their knowledge base in the implementation phase of the Australian Curriculum: History. The study used narrative inquiry to show how temporality, sociality, and place play out in the lives of these teachers of history. The findings from this study indicate the challenges and opportunities for teachers’ professional knowledge landscapes in times of curriculum reform. Whilst there are a small number of participants in this study, their stories provide insight into how teachers responded to the challenges and opportunities of teaching history and how these teachers have shaped the implementation of the history curriculum.  相似文献

ISM-CMAP-Combine (ICMC) for hierarchical knowledge scenario in quality engineering education     

R. K. Upadhyay  S. K. Gaur  V. P. Agrawal  K. C. Arora 《European Journal of Engineering Education》2007,32(1):21-33

Quality assurance in engineering education is a multifaceted problem further augmented by the stakeholders of engineering education. Students, parents and employers are rightfully questioning the quality of the curriculum, the instructional delivery, the learning environment, accessibility to learning technologies and equipment, employability as well as the possibilities of lifelong learning and the improvement of knowledge (Karapetrovic 2002 Karapetrovic, S. 2002. Why and how to develop a meaningful quality assurance system in engineering schools. Int. J. Engg. Educ, 18(3): 285–294. [Web of Science ®] [Google Scholar]). The purpose of the study is, therefore, to identify the parameters that influence the quality of an engineering education system and develop an integrated model of hierarchical structuring and a concept map for pre-identified concept elements through a process of iterative-interactive consensus-driven methodology, as advocated by second-generation system design paradigm for evolving knowledge scenario of concepts related to quality engineering education.  相似文献   

Connecting feedback to self-efficacy: Receiving and providing peer feedback in teacher education     

《Studies in Educational Evaluation》2021

Feedback can play a vital role in fostering teacher self-efficacy. Social comparisons and feedback valence (positive vs. negative feedback) are assumed to have a large impact on self-efficacy. Therefore, how pre-service teachers perceive social comparisons and feedback valence in peer feedback and the extent to which pre-service teachers (bachelor/master students) and teacher trainers incorporate comments that can have an impact on self-efficacy into their peer feedback merit investigation. Two studies were conducted. The first showed that peer feedback consisting of a social comparison and with positive feedback valence resulted in greater willingness to improve and positive affect. The second study revealed that teacher trainers’ feedback was more specific, whereas bachelor students’ feedback contained more social comparisons than did master students’ and teacher trainers’. Future research and practical implications are discussed.  相似文献
