The stretchiness of learning the digital mystery of learning in one-to-one environments in schools

The aim of the study is to generate knowledge of how teachers change their teaching and how pupils change their learning as a consequence of working in One-to-One environments in schools. The result shows that teachers and students are changing their relation to teaching and learning when school is digitized. The most important dimension of this change is that content related knowledge of the digitized learning in a one-to-one school, is a prerequisite for improved quality and better results in schools where digital artefacts are used. The results also show in what ways teachers must understand that knowledge is stretched between analogue and digital teaching and learning in the classroom.     

How Students Verify Conjectures: Teachers’ Expectations

Eight teachers were interviewed concerning how students verify conjectures. The study is a sequel to a previous study, “How Students Verify Conjectures” [Bergqvist, T. (2000). How students verify conjectures. Research reports in Mathematics Education 3]. Teachers’ expectations of students’ reasoning and performance are examined, and also how they wish students would work. The results indicate that the teachers tend to underestimate the students’ reasoning levels and that they believe that only a small group of students in each class can use higher level reasoning in mathematics.     

Modeling acquisition of an advanced skill: The case of Morse code copying

To determine characteristics of those who pass, 21 soldiers were tracked through a course in Morse code copying. Passers differed from attrites in the form of functions relating reaction times to presentation speed (p < 0.05). We suggest this is due to differing rates of copying behind and offer a model in which an initially speeded task converts, at expert level, to one of delayed responding. We then show how the model explains otherwise puzzling data. This success demonstrates the need to understand the information-processing complexities of an advanced skill before an appropriate student model can be created for instructional purposes.     

Little more than personality: Dispositional determinants of test anxiety (the Big Five, core self-evaluations, and self-assessed intelligence)

This study attempted a hierarchical integration of several dispositional determinants of test anxiety (TA) [Sarason, I.G. (1984). Stress, anxiety and cognitive interference: Reactions to tests. Journal of Personality and Social Psychology, 46, 929–938.], namely the Big Five personality traits [Costa, P.T. Jr., & McCrae, R.R. (1992). Revised NEO personality inventory (NEO-PI-R) and NEO five-factor inventory (NEO-FFI): Professional manual. Odessa: Psychological Assessment Resources.], core self-evaluations (CSE) [Judge, T.A., Erez, A., Bono, J.E., & Thoreson, C.J. (2003). The Core Self-Evaluation Scale: Development of a measure. Personnel psychology, 56, 303–331.], and self-assessed intelligence (SAI) [Furnham, A. (2001). Self-estimates of intelligence: Culture and gender difference in self and other estimates of both general (g) and multiple intelligences. Personality and Individual Differences, 31, 1381–1405.] in a sample of 388 US and UK university students. Structural equation models showed that TA was largely a function of Neuroticism, and that CSE and SAI do not contribute to the prediction of TA over established personality traits. Furthermore, the relationship between CSE and TA was fully accounted for by personality traits, whereas SAI was not a significant predictor of TA. The results undermine the notion that self-beliefs affect TA and suggest that wider dispositions play a salient role determining individual differences in TA. Theoretical and applied implications are discussed, particularly in regards to educational settings.

Consumer databases as practical accomplishments: the making of digital objects in three movements

This paper aims to reflect on some key issues linked to the production of digital objects in business settings. In doing so, it problematizes current social science scholarship, which emphasizes the analysis of digital data and analytics, and reinforces the magnitude of its consequences and ‘data power’. The paper proposes making three corrective ‘movements’ that might enrich our approaches to how databases and analytics are assembled in business settings. The first movement involves the problem of ethnographic access to data-making practices. We propose taking seriously the issue of fabricating an ethnographic encounter where the process of making digital objects is exposed. The second movement concerns the visibility and the type of politics taking place in data practices. We argue for the need to displace attention from data impacts and results to the myriad of mundane practices and devices through which these objects are assembled. The third movement we suggest requires a focus on examining error and failure as key aspects of the manufacturing of consumer databases. Each of these movements is illustrated by ethnographic vignettes from a 9-month ethnographic experiment that involved participating in the first stages of the manufacturing of an online financial retail company's consumer database.     

Classification of lunge biomechanics with multiple and individual inertial measurement units

Lunges are a common, compound lower limb resistance exercise. If completed with aberrant technique, the increased stress on the joints used may increase risk of injury. This study sought to first investigate the ability of inertial measurement units (IMUs), when used in isolation and combination, to (a) classify acceptable and aberrant lunge technique (b) classify exact deviations in lunge technique. We then sought to investigate the most important features and establish the minimum number of top-ranked features and decision trees that are needed to maintain maximal system classification efficacy. Eighty volunteers performed the lunge with acceptable form and 11 deviations. Five IMUs positioned on the lumbar spine, thighs, and shanks recorded these movements. Time and frequency domain features were extracted from the IMU data and used to train and test a variety of classifiers. A single-IMU system achieved 83% accuracy, 62% sensitivity, and 90% specificity in binary classification and a five-IMU system achieved 90% accuracy, 80% sensitivity, and 92% specificity. A five-IMU set-up can also detect specific deviations with 70% accuracy. System efficiency was improved and classification quality was maintained when using only 20% of the top-ranked features for training and testing classifiers.     

Rethinking the ownership of information in the 21st century: Ethical implications

This paper discusses basic concepts and recentdevelopments in intellectual property ownership in theUnited States. Various philosophical arguments havepreviously been put forward to support the creation andmaintenance of intellectual property systems. However, in an age of information, access toinformation is a critical need and should beguaranteed for every citizen. Any right of controlover the information, adopted as an incentive toencourage creation and distribution of intellectualproperty, should be subservient to an overriding needto ensure access to the information. The principlesunderlying intellectual property regimes in the UnitedStates recognize and embody this. In addition, thephilosophical/ethical dimensions of this debate couldalso be structured to support this attitude as well. Intellectual property is fast becoming digitalproperty. New technologies allow owners to extendtheir control of both legitimate uses and misuses ofthe intellectual property. Recent trends demonstratethat the access principle has not always beenparamount in judicial or legislative applications. Thetrend rather is to allow a proprietarianism factor todominate the analysis. Finally, several principles areforwarded which would assist adjudicators and policymakers in reaffirming the basic purpose of theintellectual property law, which is to benefit thepublic at large.     

Linking curriculum theory and linguistics: the performative use of ‘equivalence’ as an educational policy concept

The linguistic turn has helped to create new methods within social and educational theory. This study draws attention to the constitutive force of political language and the performative dynamics of one essentially contested concept—equivalence—in Swedish educational policy at both the national and the local level. It illustrates the way in which different interpretations of the concept of equivalence produce different truths, the performative concept thereby becoming a way of advocating particular understandings of the purpose of education.     

Potential of service-learning to promote sustainability competencies in pre-service teachers: a case study

This research investigates the potential of service-learning to develop a situated, embodied and critically reflective human agency for sustainability. It employs document analysis to review the intended curriculum and the institutional contexts of national and international cases wherein service-learning is a component of pre-service teacher education. Exploration of intended learning outcomes and project and assessment experiences across three cases reveal the potential of service-learning to develop in pre-service teachers sustainability competencies involving participative action with community partners to achieve agreed-upon outcomes, as well as critically reflective capacities and understanding of how, in their future classrooms, schools and communities, they can serve as adaptive, lifelong learners and agents for social and environmental change. Findings also suggest that explicitly linking service-learning activities, guided by social justice and equity principles, with a (social) sustainability agenda may further validate the utilisation of and investment in service-learning and civic engagement in teacher and higher education settings.
