Making sense of learner and learning Big Data: reviewing five years of Data Wrangling at the Open University UK

Most distance learning institutions collect vast amounts of learning data. Making sense of this ‘Big Data’ can be a challenge, in particular when data are stored at different data warehouses and require advanced statistical skills to interpret complex patterns of data. As a leading institute on learning analytics, the Open University UK instigated in 2012 a Data Wrangling initiative. This provided every Faculty with a dedicated academic with expertise data analysis and whose task is to provide strategic, pedagogical and sense-making advice to staff and senior management. Given substantial changes within the OU (e.g. new Faculty structure, real-time dashboards, two large-scale adoptions of predictive analytics approaches, increased reliance on analytics), this embedded case study provides an in-depth review of lessons learned of five years of data wrangling. We will elaborate on the design of the new structure, its strengths and potential weaknesses, and affordances to be adopted by other institutions.     

Transformative and emancipatory literacy to empower

ABSTRACT

This paper draws on sociological and critical educational frames, particularly Bourdieu’s concept of symbolic violence, in order to contest the dominant model of literacy education that is driven by the premise of a ‘knowledge economy’. Instead it foregrounds the political, social, and economic factors that marginalise learners. Data from two projects: an ethnographic study in a Further Education (FE) College in England and a study of community-based literacy programmes in Scotland, are probed to show how literacy classes can offer spaces to challenge symbolic violence and facilitate learners to reclaim identities of success. These changes are illustrated from the learners’ views of the contrasts between their experiences of school education and literacy programmes that use transformative and emancipatory approaches. Our research demonstrates how critical education can open up spaces for a more equitable approach based on the co-production of knowledge. It is argued that making changes to policy and practice could inform and shape the literacy curriculum and its pedagogy if adult literacy can disentangle itself from instrumental approaches driven by neoliberal fusion and instead create critical space for contextualised and emancipatory learning.     

Primary physical education subject leadership: along the road from in-house solutions to outsourcing

The modern primary school is a complex institution containing a growing community of individuals and organisations with potentially competing agendas. Within this environment, subject leaders are typically looked upon for advice and guidance within a given subject area such as Physical Education. Yet for those endeavouring to provide Physical Education subject leadership within primary schools, the challenge has grown significantly over the last two decades amidst an ever-changing policy landscape. This paper is for and about primary Physical Education subject leadership; the purpose of which, to plot primary Physical Education's policy journey and explore the implications of reform in shaping the subject leader's role. The paper addresses the current lack of guidance for the subject leader and examines the professional knowledge, skills and experience required to do the role effectively.     

Technical characteristics of the peabody individual achievement test as a function of item arrangement and basal and ceiling rules

The effects that item order and basal and ceiling rules have on test means, variances, and internal consistency estimates for the PIAT mathematics and reading recognition subtests were examined. Seven items on the math subtest and one item on the reading recognition subtest were significantly easier or harder than their test placement indicated. The use of basal and ceiling rules had a pronounced effect on the means, variances, and reliabilities on the multiple choice math subtest, while the rules' effects on the reading recognition subtests were minor. Item order also affected scores on the math subtest.     

Chronic flexibility gains: effect of isometric contraction duration during proprioceptive neuromuscular facilitation stretching techniques

The aim of this study was to assess the effect of to isometic contraction durations during propiceptive neuromuscular facilitation stretching on gains inflexion at the hip. Forty-three women (M age = 20.0 years, SD = 1.3) were assigned to one of three groups: 5-s isometric contraction (5-IC), 10-IC, and control. Flexibility was assessed at baseline and Weeks 3 and 6. Analysis of covariance, controlling for pretest differences, showed a significant interaction, F(2, 33) = 44.1, p < .001. Flexibility was significant lower in the control group relative to the 5-IC and 10-IC groups and in the 5-IC group relative to the 10-IC group at 3 and 6 weeks (3 weeks = 101.2 +/- 1.4 degrees, 114.3 +/- 1.5 degrees, 120.5 +/- 1.3 degrees; 6 weeks = 103.0 +/- 1.4 degrees, 126.1 +/- 1.6 degrees, 133.3 +/- 1.4 degrees for control, 5-IC and 10-IC groups, respectively). A longer contraction time led to greater increases in flexibility.     

Indigenous students' persistence in higher education in Australia: contextualising models of change from psychology to understand and aid students' practices at a cultural interface

The need to address the substantial inequities that exist between Indigenous and non-Indigenous Australians in higher education is widely recognised. Those factors that affect the performance of Indigenous students in tertiary education have been reasonably well documented across different institutions, disciplines, and programme levels but there has, to date, been less consideration of the processes by which Indigenous students either persist or desist in higher education. This paper aims to present a conceptual understanding of academic persistence that can inform the delivery of tailored academic support interventions to Indigenous students who are at high risk of leaving higher education.     

Mastery Motivation in Children with Intellectual Disability: Is there Evidence for a Down Syndrome Behavioural Phenotype?

The main purpose of the current study was to provide empirical evidence to support or refute assumptions of phenotypic deficits in motivation for children with Down syndrome (DS). Children with moderate intellectual disability (MID) associated with etiologies other than DS were recruited in an extension of a previous study that involved children with DS and typically developing children. The participants were 29 children with MID and 33 children with DS who were matched on mental age to 33 typically developing children, aged 3–8 years. Mastery motivation was assessed on task measures of curiosity, preference for challenge and persistence, as well as parental reports. There were no significant group differences on the mastery motivation tasks. Parental ratings of mastery motivation differed, with typically developing children generally being rated more highly than each of the disability groups. The view that motivational deficits are part of the DS behavioural phenotype was not supported.     

Digital body preservation: Technique and applications

High-fidelity anatomical models can be produced with three-dimensional (3D) scanning techniques and as such be digitally preserved, archived, and subsequently rendered through various media. Here, a novel methodology—digital body preservation—is presented for combining and matching scan geometry with radiographic imaging. The technique encompasses joining layers of 3D surface scans in an anatomical correct spatial relationship. To do so, a computed tomography (CT) volume is used as template to join and merge different surface scan geometries by means of nonrigid registration into a single environment. In addition, the use and applicability of the generated 3D models in digital learning modalities is presented. Finally, as computational expense is usually the main bottleneck in extended 3D applications, the influence of mesh simplification in combination with texture mapping on the quality of 3D models was investigated. The physical fidelity of the simplified meshes was evaluated in relation to their resolution and with respect to key anatomical features. Large- and medium-scale features were well preserved despite extensive 3D mesh simplification. Subtle fine-scale features, particular in curved areas demonstrated the major limitation to extensive mesh size reduction. Depending on the local topography, workable mesh sizes ranging from 10% to 3% of the original size could be obtained, making them usable in various learning applications and environments.
