Sampling Methods and Sample Populations in Quantitative Mass Communication Research Studies: A 15-Year Census of Six Journals     

Joseph Erba  Brock Ternes  Piotr Bobkowski  Tara Logan  Yuchen Liu 《Communication Research Reports》2018,35(1):42-47

This study evaluated the sampling methods and sample populations used in all U.S.-based survey and experimental mass communication studies published between 2000 and 2014 in six major journals (N = 1,173). Most studies used nonprobability samples, and more than half used student samples. Experiments used more nonprobability and student samples than surveys. Funded studies used more probability and nonstudent samples than nonfunded studies. Implications of results pertaining to population validity and interpretations of findings for mass communication research are discussed.  相似文献   

Can a systematic assessment moderation process assure the quality and integrity of assessment practice while supporting the professional development of casual academics?

There has been a threefold increase in the employment of casual academics in Australian universities within the last 20 years, to the extent that most teaching and marking is now undertaken by casual academics, also known as sessional staff. Yet, casualised teaching and assessment has been considered a risk to student engagement and success, and casual academics report a lack of professional development and increased feelings of marginalisation within the academy. Concurrently, the quality assurance of teaching and assessment in higher education has become a central focus of the government-funded regulatory organisation, the Tertiary Education Quality and Standards Agency (TEQSA). Situated within this context, we report on an assessment moderation process that could support casual academics’ contextualised professional development, generate a sense of connectedness and collegiality and fulfil the requirements of TEQSA. Such processes may ensure that workforce growth in the higher education system supports a robust quality assurance and regulatory framework.  相似文献

“We must educate our masters”     

Michael Brock 《牛津教育评论》2013,39(3):221-232

In this paper we examine the possible explanations for the patterns of results found at Oxford, in which women students consistently achieve a lower proportion of both first and third class honours. Usual explanations that rest on socio‐biology or simple forms of socialisation are rejected in favour of an explanation which is based on the idea of a mutual determination of social structure and social being. Various hypotheses are proposed as possible explanations of the examination statistics.  相似文献

Teachers' Emotional Support Consistency Predicts Children's Achievement Gains and Social Skills     

Timothy W. Curby  Laura L. Brock  Bridget K. Hamre 《Early education and development》2013,24(3):292-309

Research Findings: It is widely acknowledged that consistent, high-quality teacher–student interactions promote optimal developmental outcomes for children. Previous research on the quality of teacher–student interactions provides empirical support for this premise. Little research has been conducted on the consistency of teacher–student interactions. This study examines whether consistency in teachers' emotional support is related to better academic and social outcomes for children. Multiple observations were conducted in 694 prekindergarten classrooms. Mean levels of emotional support and consistency of emotional support were used as predictors in multilevel models. Results indicated that when mean levels of emotional support were controlled, within-day consistency of emotional support predicted several academic outcomes in prekindergarten as well as social competence in kindergarten. Practice or Policy: Results indicate that teachers' consistency of emotional support is a salient aspect of children's classroom environment. Findings suggest that consistency should be considered when evaluating teachers' emotionally supportive interactions.  相似文献
