A research synthesis of magnet school effect on student outcomes: Beyond descriptive studies

Characterized by thematic instructional programs and voluntary enrollment, magnet schools are often the result of a neighborhood schooling effort to increase racial integration and academic achievement. With the continued expansion of magnet schools, it is critical that stakeholders have a comprehensive research synthesis of their potential impact. This article reviews and aggregates findings from 18 studies that evaluate magnet schools’ influence on student outcomes. Emphasis is given to the results of lottery-based studies and those utilizing prior achievement and demographic controls. Though results across studies vary substantially, effects are generally positive, particularly for magnet secondary schools.     

Using a blended learning approach to support women returning to STEM

ABSTRACT

This paper examines a blended learning model designed to support women returning to STEM after a career break and its delivery in a unique partnership between an online distance education provider and a community-based equality organisation. Through this partnership additional activities such as networking events, returnships, career clinics and webinars were used in conjunction with a structured online Badged Open Course (BOC), which enabled a successful return to employment for many of the participants. This article outlines the results and implications of this integrated model and argues that blended learning approaches need to be flexible and adaptable to be able to incorporate the needs of learners at different life-course stages, taking into consideration gender and other diversity characteristics.     

Pedagogical Reflections by Secondary Science Teachers at Different NOS Implementation Levels

This study investigated what 13 secondary science teachers at various nature of science (NOS) instruction implementation levels talked about when they reflected on their teaching. We then determined if differences exist in the quality of those reflections between high, medium, and low NOS implementers. This study sought to answer the following questions: (1) What do teachers talk about when asked general questions about their pedagogy and NOS pedagogy and (2) what qualitative differences, if any, exist within variables across teachers of varying NOS implementation levels? Evidence derived from these teachers’ reflections indicated that self-efficacy and perceptions of general importance for NOS instruction were poor indicators of NOS implementation. However, several factors were associated with the extent that these teachers implemented NOS instruction, including the utility value they hold for NOS teaching, considerations of how people learn, understanding of NOS pedagogy, and their ability to accurately and deeply self-reflect about teaching. Notably, those teachers who effectively implemented the NOS at higher levels value NOS instruction for reasons that transcend immediate instructional objectives. That is, they value teaching NOS for achieving compelling ends realized long after formal schooling (e.g., lifelong socioscientific decision-making for civic reasons), and they deeply reflect about how to teach NOS by drawing from research about how people learn. Low NOS implementers’ simplistic notions and reflections about teaching and learning appeared to be impeding factors to accurate and consistent NOS implementation. This study has implications for science teacher education efforts that promote NOS instruction.     

Research productivity and perceived teaching effectiveness: A survey of economics faculty

The relationship between research productivity and teaching effectiveness has long been a controversial topic among university professors. This study utilizes a nationwide survey of economics faculty to examine the relationship between research productivity and classroom performance, using self-reported measures of research output and teaching evaluation scores, and to solicit the participants' opinions on this issue. Findings indicate a very weak relationship between research output and teaching effectiveness. However, individual and institutional characteristics seem to explain some differences in research output and teaching evaluation scores. Further, faculty opinions on the research-teaching relationship seem to be influenced by institutional and individual characteristics.     

Forced to choose: some determinants of racial identification in multiracial adolescents

This paper categorizes multiracial youth (N=1,496) ages 14 to 19 and compares them with each other and with monoracial youth on identity development measures. The multiracial categories used here are derived from youths' reports of their own and their parents' race(s). Comparisons are made within groups of multiracial respondents who make different choices among single-race categories. Results show differences between subgroups in strength and importance of ethnic identity, self-esteem, and perceptions of ethnic discrimination. Multinomial logistic regression shows further that physiognomy, ethnic identity, and race of coresident parent(s) are significantly associated with reported race. Also related to racial identification among part-Hispanic youth are the racial distribution and socioeconomic status of their neighborhoods and the racial distributions of their schools.     

Association Between Experienced Teachers’ NOS Implementation and Reform-Based Practices

The assertion that general reform-based science teaching practices (GRBSTPs) can facilitate nature of science (NOS) instruction has been mentioned in the literature, but rigorous and transparent empirical substantiation for this claim has not been made. This investigation empirically demonstrates an association between thirteen experienced teachers’ NOS implementation practices and their GRBSTPs. While effectively implementing GRBSTPs does not ensure the NOS will be taught, the findings show that these practices are associated with high levels of NOS instruction. In this study, teachers who implemented higher levels of reform-based practices were also observed to enact more instances of planned and spontaneous effective NOS instruction. Furthermore, these teachers were more likely to recognize and capitalize on NOS teaching opportunities when they unexpectedly arose in the context of their GRBSTPs. Just as NOS understanding must be assessed when determining factors associated with teachers’ NOS implementation, teachers’ GRBSTPs should also be empirically and transparently established to ensure they do not mask or confound other factors associated with NOS implementation.

Adventures in subsemiotics: towards a new 'object' and writing of visual culture

This article focuses on a debate between Mieke Bal and James Elkins regarding the nature and scope of visual semiotics. Their research, which is concerned with the conceptualisation of the smallest ‘subsemiotic’ marks of pictures, is examined here in terms of the broader issues of visual theory and critique. The exchange between them is used to illuminate a number of key concerns about the nature of visual semiotics and the critical practice it inaugurates for visual culture research. The developments in recent visual culture discourse are presented first with the suggestion that a re-evaluation of the very ‘object’ of visual culture is required, which would bring the differing positions of Bal and Elkins to accord. The contesting positions of Bal and Elkins represent the vacillating need in visual culture for a critical discursive framework and a specifically visual orientation. By drawing much insight from the writings of Roland Barthes, the overall argument is that in order to (ad)venture forth in (sub)semiotics it is crucial to (re)consider past semiotic theory and the very ‘object’ of visual culture in and as writing itself.
