Students’ individual schematization pathways - empirical reconstructions for the case of part-of-part determination for fractions

According to the design principle of progressive schematization, learning trajectories towards procedural rules can be organized as independent discoveries when the learning arrangement invites the students first to develop models for mathematical concepts and model-based informal strategies; then to explore the strategies and to discover pattern for progressively developing procedural rules. This article contributes to the theoretical and empirical foundation of the design principle of progressive schematization by empirically investigating students’ individual schematization pathways on the micro-level for the specific case of part-of-part determination of fractions. In design experiments series in laboratory settings, nine pairs of sixth graders explored the part-of-part determination and progressively schematized their graphical strategies before discovering the procedural rule. The qualitative in-depth analysis of 760 min of video shows that progressive schematization is a multi-facetted process that cannot be described by internalization of graphical procedures alone. Instead, the compaction of concepts- and theorems-in-action is crucial, especially for the goal of justifiable procedural rules.     

Competencies and career choice motives: characteristics of high school students interested in teacher education programmes

In contrast to other career choices, the teaching profession seems familiar to those interested in teaching because they have had the chance to observe teachers for years. This phenomenon is known as the apprenticeship of observation and manifests in naïve ideas and expectations of teaching among teacher students. Therefore, characteristics of students interested in becoming teachers are important for early teacher education and counselling. These characteristics include competencies and motives, but nothing is known about their relationship to each other. Following international teaching standards and the expectancy-value framework, this paper analyses associations between both. Three competencies (i.e. planning, communication and cooperation) and seven career choice motives were examined using a paper–pencil survey of 907 high school students. Altogether, 463 students were able to imagine becoming a teacher and were included in the analyses. SEM analyses showed that (1) of all the competencies, communication had the most associations with motives, (2) the motive ‘low difficulty of study’ is positively related to planning, (3) the findings regarding extrinsic motives are ambiguous, and (4) gender differences are marginal. Practical implications for early teacher education and counselling are discussed.     

Simulating the global workplace for graduate employability

Higher education institutions increasingly recognise the need to develop both disciplinary knowledge and soft skills to foster the employability of their graduates. For students in International Studies programmes, the workplace opportunities to develop soft skills relevant to their intended professions are scarce, costly and unavailable to many. This paper argues that universities can harness the power of ICTs in ways that students find engaging and offer opportunities to gain professional experience that prepares them for an international workplace. We describe a new work-integrated learning model that embeds a multi-layered in-person simulation within an academic context. Facilitated by cross-national pedagogical collaboration, students participate live in cross-campus experiential learning with online peers. Students’ reflections on the model indicate that this model can foster a range of generic soft skills that enable them to apply their academic knowledge, collaborate with a culturally diverse group and work in a digital world. To refine this blended learning model, more attention needs to be paid to designing appropriate evaluation tools and harnessing cultural diversity more effectively.

Visual attention in orienteers at different levels of experience

This study explored how differences in orienteering experience are related to differences in how visual attention is allocated to the map, the environment and to travel. Twenty more experienced and 20 less experienced individuals orienteered while wearing a head-mounted video camera with microphone. The participants verbalized what they were attending to (map, environment or travel) at any given time. Each recorded film was coded at each point in time in terms of what the participant was attending to and whether the participant was moving or stationary. More experienced orienteers attended to the map markedly more while moving and spent less time stationary than less experienced orienteers. The participants' performance was significantly related to the ability to attend to the map while moving. The strategic control of attention is proposed to explain this ability. It is proposed that attentional training might enhance performance in sports characterized by multiple and dynamically varying elements.     

Information Literacy Instruction in an English Capstone Course: A Study of Student Confidence,Perception, and Practice

An English professor and an instruction librarian at the University of New Hampshire at Manchester felt that the college's new English Capstone course for majors provided a unique opportunity to assess the information literacy skill levels of graduating English majors. They therefore engaged in a three-year study to evaluate the IL competency of these students, to gauge their perceptions of library instruction provided during the Capstone course and throughout their academic careers, and to determine students' confidence and self-efficacy with respect to these skills. The researchers sought to determine the ways in which the IL program for English majors effectively met established IL goals and to identify areas for improvement.     

Word length and word frequency affect eye movements in dyslexic children reading in a regular (German) orthography

We combined independently the word length and word frequency to examine if the difficulty of reading material affects eye movements in readers of German, which has high orthographic regularity, comparing the outcome with previous findings available in other languages. Sixteen carefully selected German-speaking dyslexic children (mean age, 9.5 years) and 16 age-matched controls read aloud four lists, each comprising ten unrelated words. The lists varied orthogonally in word length and word frequency: high-frequency, short; high-frequency, long; low-frequency, short; low-frequency, long. Eye movements were measured using a scanning laser ophthalmoscope (SLO). In dyslexic children, fixation durations and the number of saccades increased both with word length and word frequency. The percentage of regressions was only increased for low-frequency words. Most of these effects were qualitatively similar in the two groups, but stronger in dyslexic children, pointing to a deficient higher-level word processing, especially phonological deficit. The results indicate that reading eye movements in German children are modulated by the degree of difficulty, and orthographic regularity of the language can determine the nature of modulation. The findings suggest that, similar to Italian but unlike English readers, German children prefer indirect sub-lexical strategy of grapheme-phoneme conversion.     

Productivity effects of basic research in low-tech and high-tech industries

R&D encompasses plenty of activities which are usually summarized under the terms of basic research, applied research and development. Although basic research is often associated with low appropriability it provides the fundamental basis for subsequent applied research and development. Especially in the high-tech sector basic research capabilities are an essential component for a firm's success. We use firm-level panel data stemming from Belgian R&D surveys and apply a production function approach which shows that basic research exhibits a premium on a firm's output when compared to applied research and development. When we split the sample into high-tech and low-tech companies, we find a large premium of basic research for firms in high-tech industries, but no premium in low-tech sectors.     

Organ economy: organ trafficking in Moldova and Israel

Organ trafficking is an illegal means of meeting the shortage of transplants. The activity flourishes for several interacting reasons, such as medical needs, poverty and criminality. Other factors are fundamental conceptual structures such as the dream of the regenerative body as well as the view of the body as an object of utility and an object of value. The article aims to go behind the normative discussions that usually surround organ trafficking. Why this is happening, and what the societal consequences are, is examined through ethnographic fieldwork. The focus is on the shadow economies that govern existence and in which people, goods, weapons, money, bodies, etc. constitute components of the global market.
