This dissertation examines two related questions. "How do mixed membership models work?" and "Can mixed membership be used to model how students use multiple strategies to solve problems?". Mixed membership models have been used in thousands of applications from text and image processing to genetic microarray analysis. Yet…

Increasingly, many of our higher education teaching staff hail from diverse backgrounds with cultures that are often dissimilar to the world of academia. Drawn to education as a second career, or courted from industry for real world verisimilitude, their experience and external sector knowledge can be invaluable to an institution, but of little…

Using survey data from novice teachers across 99 schools, we estimated multilevel regressions to identify the association between novices' intent to remain teaching within their schools and their perceptions of the collegial climate. The results suggest that novice teachers who perceive a more positive collegial climate marked by higher degrees…

Principals have a clear impact on the transition of teachers into their initial work setting (Allensworth, Ponisciak, Mazzeo, 2009; S. T. Bickmore & D. L. Bickmore, 2010; Scherff, 2008). School administrators' influence on teacher induction is both organizational and relational as they develop structures and practices that support…

This article presents a co-teaching model for developing teaching effectiveness, illustrated with a case example portraying the experiences of two doctoral students who co-developed and co-taught an undergraduate course. As future educators, the doctoral students profited from the unique opportunities co-teaching provided for skills and…

The visual word form system (VWFS), located in the occipito-temporal cortex, is involved in orthographic processing of visually presented words (Cohen et al., 2002). Recent fMRI studies in children and adults have demonstrated a gradient of increasing word-selectivity along the posterior-to-anterior axis of this system (Vinckier et al., 2007), yet…

Onboarding is a new employee orientation process that is designed to formalize and socialize new hires to an organization, or in this case higher education institutions. The onboarding experience that many new employees have can shape employee views and first impressions of their new employer, and shape their early career path to stay or leave…

Spatial thinking is fundamental to the practice and theory of geography, however there are few valid and reliable assessment methods in geography to measure student performance in spatial thinking. This article presents the development and evaluation of a geospatial thinking assessment instrument to measure participant understanding of spatial…

Though literature discussions are a commonplace feature of English classrooms, we know little about how teachers learn to facilitate classroom talk. Research on methods courses reveals little about how, or if, teachers are prepared to enact the "high leverage" practice of literature discussions. This qualitative study examines an English…

We assessed the impact of expert students' instructional quality on the academic performance of novice students in 12th-grade physics classes organized in an expert model of cooperative learning ("jigsaw classroom"). The instructional quality of 129 expert students was measured by a newly developed rating system. As expected, when…

Research on the effectiveness of introductory programming environments often relies on post-test measures and attitudinal surveys to support its claims; but such instruments lack the ability to identify any explanatory mechanisms that can account for the results. This paper reports on a study designed to address this issue. Using Noss and Hoyles'…

Purpose: This article aims to explore the concept of amateurism as a form of critique and addition to the concepts of professionalism, professional work and education. Design/methodology/approach: This is a theoretically driven article based upon a review of the historical and sociological literature on amateur-professional relations in various…

This self-study explores the emerging identity of a first-time teacher educator using a framework that views identity as natural, institutional, discursive, and affinity. This framework provided an opportunity to unpack empirically how these various strands of identity intersected within the classroom of a novice teacher educator. Situated in the…

Vocabulary learning is a crucial factor in second language acquisition (SLA), yet there is no consensus as to how to present vocabulary in a way that facilitates learning. Little theory and scant empirical evidence support the claim that presenting words in semantic clusters facilitates vocabulary acquisition, yet most text books present SL…

Case-based instruction (CBI) offers a promising method for promoting problem-solving skills in learners. However, during CBI, the instructor shoulders major responsibility for shaping the learning that takes place. Research indicates that the facilitation techniques used during case discussions influence what gets covered, and to what extent,…
