Sketching,not representational competence,predicts improved science learning

Representational competence is a target of novel learning environments given the assumption that improved representational competence improves learning in science. There exists little evidence, however, that improving representational competence is positively correlated with learning outcomes across science disciplines. In this report, we argue that the previously reported weak relationships between representational competence and science learning outcomes have resulted from designs that do not explicitly analyze the discipline‐specific skills related to the representational competence construct. Here, we demonstrate through a detailed analysis of students' representation use that at least two demonstrated skills comprising representational competence (e.g., construction and selection) are not strongly related to improved conceptual understanding in the domain. We discuss the implications of these results for the design of future learning environments that aim to improve learning through improved representational competence.     

Levelling the playing field between rural schools and urban schools in a HE context: A Scottish case study

At a time when interventions in widening access to, and participation in, higher education aim to maximise impact by engaging with schools located in the most deprived communities, school pupils in rural communities, and who experience deprivation, are, in practice, less likely to benefit. Using statistics available from the Scottish government, we show that state secondary schools located in Scottish remote or rural areas are not well served by the indicators capturing socio-economic, educational, or geographical deprivation widely used in the selection of schools for these outreach interventions. We construct a marker that identifies schools facing higher levels of deprivation than the Scottish average. We argue that (1) this marker is a step in the direction towards levelling the playing field between remote or rural schools and urban schools; and (2) it selects a wider range of schools for outreach interventions.

Tests as boundary signifiers: level 6 tests and the primary secondary divide

This paper addresses the question: How do teachers and school leaders respond to high stakes testing of pupils transitioning from primary to secondary school? It explores how a new test, the Level 6 test, operated with regard to primary/secondary school relationships in England. It draws on an analysis of qualitative interviews with teachers and school leaders in 20 primary schools that took part in the test, 40 school leaders that chose not to and 20 secondary-school leaders. Theoretical work on social boundaries is utilised to develop an argument that this test and its results acted as a boundary signifier, crystallising many of the tensions between primary and secondary schools. These tensions included the role of accountability regimes in requiring schools to demonstrate progress; narrowing of the curriculum and teaching to the test; and the extent to which test results can provide a true representation of pupil attainment. We conclude by suggesting the potential of the boundary signifier concept in relation to other tests at the primary/secondary boundary and other key transition points in education, and consider whether such tests can act as an ideal boundary object, serving to help overcome, rather than cement, barriers between schools.     

Situating Vocationalism

The approaches taken to the analysis of vocationalism within the sociology of education have been dominated by the concept of the New Right and have operated within a dominant strong‐state/free market paradigm based upon an analysis of the Thatcherite project. I argue that vocationalist ideologies should be more properly linked to an emerging ‘statist’ model of capitalism in which the state intervenes to create the conditions for greater international competitiveness. However neither this, nor other legitimations of vocationalism in terms of its supposed Jit’ with a new post‐fordist economy, can be seen to cany complete conviction.

Beyond internationalisation and isomorphism – the construction of a global higher education regime

ABSTRACT

National higher education systems are undergoing profound changes, discussed in many but unrelated studies as outcomes of internationalisation dynamics and institutional isomorphism pressures. We propose to link these studies by emphasising the influence of both internationalisation and isomorphism on the formation of a global educational regime. Through a broad range of indicators, we describe the growth of the discursive, normative, and regulatory dimensions of such a global higher education regime. We find evidence of the following developments: (1) a rapidly growing network of international organisations focused on conferences, initiatives, and programmes supporting a global higher education agenda; (2) a striking increase in the number of international and national accreditation agencies, their mutual cross-national recognition as well as the number of universities that are nationally and internationally accredited; and lastly, (3) parallel increases in regional qualification frameworks and in the implementation of national qualification frameworks. These developments create integration pressures manifest in the mutual recognition of higher education degrees, for which a new generation of regional conventions has emerged worldwide in the past two decades. We discuss these processes and their implications for understanding ‘national’ higher education as well as the threats and limits to the burgeoning higher education regime.     

Multilevel Rasch Modeling: Does Misfit to the Rasch Model Impact the Regression Model?

Abstract

Multilevel Rasch models are increasingly used to estimate the relationships between test scores and student and school factors. Response data were generated to follow one-, two-, and three-parameter logistic (1PL, 2PL, 3PL) models, but the Rasch model was used to estimate the latent regression parameters. When the response functions followed 2PL or 3PL models, the proportion of variance explained in test scores by the simulated student or school predictors was estimated accurately with a Rasch model. Proportion of variance within and between schools was also estimated accurately. The regression coefficients were misestimated unless they were rescaled out of logit units. However, item-level parameters, such as DIF effects, were biased when the Rasch model was violated, similar to single-level models.     

Cognitive development,genetics problem solving,and genetics instruction: A critical review

Recent studies have analyzed the cognitive demands of solving problems in genetics, focusing primarily on the Piagetian schemas of combinations, proportions, and probability. Based on data from these primarily correlational studies, some authors have argued for the elimination of classical genetics from the high school curriculum. The critical review of the literature presented in this article reaffirms that formal-operational thought is conducive to successful genetics problem solving. The weight of the evidence to date, however, does not support the position that formal operational thought is strictly required for solving typical genetics problems. Arguments are therefore presented in support of the inclusion of genetics and genetics problem solving in high school biology. Implications of this analysis for the selection of appropriate content, problems, and instructional techniques for genetics instruction for nonformal students are presented.
