Learning of Core Disciplinary Ideas: Efficacy Comparison of Two Contrasting Modes of Science Instruction

Science curricula and teaching methods vary greatly, depending in part on which facets of science are emphasized, e.g., core disciplinary ideas or science practices and process skills, and perspectives differ considerably on desirable pedagogies. Given the multi-faceted nature of science and the variety of teaching methods found in practice, it is no simple task to determine what teaching approaches might be most effective and for what purposes. Research into relative efficacy faces considerable challenges, with confounding factors, ambiguities, conflations, and lack of controls being threats to validity. We provide a conceptual framework characterizing the many teaching strategies found in practice as being variants of two fundamental contrasting epistemic modes, and we disentangle conflations of terms and confusions of constructs in both teaching practice and research. Instructional units for two science topics were developed in parallel in the alternative epistemic modes, differing in concept learning paths but otherwise equivalent. We conducted a randomized controlled study of the comparative efficacy of the two modes for learning core disciplinary ideas, using operationally defined active-direct and guided-inquiry teaching methods. Five middle school teachers taught each unit in both modes over 4 years of classroom trials in an 8-day summer program for eighth grade students. Student understanding of core ideas was assessed using pre- and post-tests, and learning gains were analyzed by mode, teacher, topic, and trial year. Although routes to concept understanding were very different in the two modes, eventual student learning gains were similar, within statistical variation. Efficacy variations between and within teachers were greater than between modes, indicating the importance of teacher effects on student achievement. Findings suggest that teachers need not be bound to one mode throughout and can flexibly decide on the pedagogical approach for each concept and situation, on several grounds other than efficacy of core content acquisition alone.     

An exploration of trans* kinship as a strategy for student success

Abstract

Although the notion of queer kinship has been well discussed within literature on queer individuals, it has not been used as a lens to make sense of how trans* college students successfully navigate rigidly gender dichotomous collegiate environments. Using interview data from the National Study of LGBTQ Student Success, this study explores the narratives of 18 trans* students concerning their experiences of success in college and the role of queer kinship in supporting their success. Analysis documented three domains of kinship (i.e. material, virtual, and affective), which promoted students’ success.

Diverse Expectations and Access to Opportunities: is there a Graduate Labour Market?

Restructuring of the labour market has led to changing demand for skills and concern about potential mismatch between needs of employers and competences developed in higher education courses. This paper extends analysis of the Great Expectations survey of UK final-year undergraduates in 1996 to explore the development of skills and competences in different disciplinary areas and the anticipated career trajectories of students. A detailed assessment is undertaken of the extent to which respondents appear prepared, both in terms of the employment-related skills they consider they have developed as undergraduates and in their expectations, for the changes which have taken place in the labour market in the latter part of the twentieth century. While findings from transitional early careers need to be interpreted cautiously, it does appear that expectations varied less than emerging outcomes for this cohort in the vanguard of mass higher education. Subject and gender differences in expectations and outcomes were significant and 'non-traditional' graduates were more likely than others to report that they were experiencing difficulties in the transition from education to employment. The graduates themselves had a flexible approach to the labour market but it seems that employers may have more inflexible recruitment graduate practices. Further research is required but there is clearly a danger that wider access may not lead to correspondingly wider career opportunities.     

Do We Have a Trust Problem? Exploring Undergraduate Student Views on the Tentativeness and Trustworthiness of Science
