Rationalising for and against a policy of school-led careers guidance in STEM in the U.K.: a teacher perspective

This paper reports on teacher attitudes to changes in the provision of careers guidance in the U.K., particularly as it relates to Science, Technology, Engineering and Mathematics (STEM). It draws on survey data of n?=?94 secondary-school teachers operating in STEM domains and their attitudes towards a U.K. and devolved policy of internalising careers guidance within schools. The survey presents a mixed message of teachers recognising the significance of their unique position in providing learners with careers guidance yet concern that their ‘relational proximity’ to students and ‘informational distance’ from higher education and STEM industry may produce bias and misinformation that is harmful to their educational and occupational futures.     

Moving Beyond the Lecture: Inspiring Social Justice Engagement through Counter-Story Using Case Study Pedagogy

Abstract

The paper examines participant perceptions of the effectiveness of using case studies with college students (undergraduate – doctoral) to teach social justice and educational equity. Findings indicate that participants who identified with the characters in the cases were able to draw connections between the case and their own personal experiences. They felt the cases broadened their understanding of the topics and increased their sense of empathy and their commitment to principles of social justice.

Unravelling the interplay of sources of self-efficacy in negotiating in role-play simulations of political decision-making: A longitudinal in-depth case study

This study contributes to current self-efficacy research in two ways. First, it responds to the need for more context- and competency-specific self-efficacy research by expanding the research field to the context of role-play simulations and focusing on the outcome of self-efficacy in negotiating. Second, aiming to investigate sources of self-efficacy and their interplay, the study addresses the need for more in-depth qualitative research by conducting a single holistic case study with a longitudinal design. Moreover, the study focuses on outcomes of an increase or decrease in self-efficacy over time. Data were collected during a four-day European Union simulation. Three data sources – diaries, interviews, and semi-structured observations and field notes – contributed to data convergence, ensuring that more than a single source of evidence supported findings. Four students were selected using maximum variation sampling. The final sample of 27 meaningful events – about the development of self-efficacy in negotiating – were selected by within-case sampling based on a set of inclusion criteria. Data were analyzed by means of content analysis. Three groups of sources of self-efficacy could be defined: personal sources, social sources, and contextual sources, which encompassed and enriched the four previously hypothesized sources of self-efficacy. With regard to the interplay of sources, five main pathways could be defined. Personal sources were present in all pathways. The contribution of social sources to an increase in self-efficacy was more obvious than its role in a decrease in self-efficacy. The contribution of the contextual source to the development of self-efficacy in negotiating was generally less prominent.

Do altmetrics assess societal impact in a comparable way to case studies? An empirical test of the convergent validity of altmetrics based on data from the UK research excellence framework (REF)

Altmetrics have been proposed as a way to assess the societal impact of research. Although altmetrics are already in use as impact or attention metrics in different contexts, it is still not clear whether they really capture or reflect societal impact. This study is based on altmetrics, citation counts, research output and case study data from the UK Research Excellence Framework (REF), and peers’ REF assessments of research output and societal impact. We investigated the convergent validity of altmetrics by using two REF datasets: publications submitted as research output (PRO) to the REF and publications referenced in case studies (PCS). Case studies, which are intended to demonstrate societal impact, should cite the most relevant research papers. We used the MHq’ indicator for assessing impact – an indicator which has been introduced for count data with many zeros. The results of the first part of the analysis show that news media as well as mentions on Facebook, in blogs, in Wikipedia, and in policy-related documents have higher MHq’ values for PCS than for PRO. Thus, the altmetric indicators seem to have convergent validity for these data. In the second part of the analysis, altmetrics have been correlated with REF reviewers’ average scores on PCS. The negative or close to zero correlations question the convergent validity of altmetrics in that context. We suggest that they may capture a different aspect of societal impact (which can be called unknown attention) to that seen by reviewers (who are interested in the causal link between research and action in society).
