Examining the relationship between emotion variability,self-regulated learning,and task performance in an intelligent tutoring system

Educational technology research and development - Prior research has focused extensively on how emotion tendencies (e.g., duration, frequency, intensity, and valence) affect students’...     

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.     

Do expert clinical teachers have a shared understanding of what constitutes a competent reasoning performance in case-based teaching?

To explore the assessment challenge related to case based learning we study how experienced clinical teachers—i.e., those who regularly teach and assess case-based learning—conceptualize the notion of competent reasoning performance for specific teaching cases. Through an in-depth qualitative case study of five expert teachers, we investigate whether they share a common concept of what constitutes a good reasoning performance for a set of three teaching cases. We ask expert teachers to reflect on their problem-solving performances to extract specific expectations regarding the assessment of learners. Using visual representations of their performance, experts inspect and identify whether key elements are considered critical, necessary, and useful for the assessment of learners’ performance. Findings indicate that despite solving cases differently, expert teachers share a common concept regarding the key elements that demonstrate good clinical reasoning for specific cases. These results and methods used to trigger assessment criteria from expert clinical teachers show potential for the development of process measures in the assessment of clinical reasoning.     

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.     

Taking away and determining the difference—a longitudinal perspective on two models of subtraction and the inverse relation to addition

Subtraction can be understood by two basic models—taking away (ta) and determining the difference (dd)—and by its inverse relation to addition. Epistemological analyses and empirical examples show that the two models are not relevant only in single-digit arithmetic. As curricula should be developed in a longitudinal perspective on mathematics learning processes, the article highlights some exemplary steps in which the inverse relation is discussed in light of the two models, namely mental subtraction, the standard algorithms for subtraction, negative numbers and manipulations for solving algebraic equations. For each step, the article presents educational considerations for fostering a flexible use of the two models as well as of the inverse relation between subtraction and addition. In each section, a mathe-didactical analysis is conducted, empirical results from literature as well as from our own case studies are presented and consequences for teaching are sketched.     

Internal and external influences on vocabulary development in preschool children

Competency in society's lingua franca plays a major role in the emergence of social disparities within education. Therefore, the present longitudinal study investigates vocabulary development and its predictors in preschool years. We focus on whether internal (phonological working memory) and external variables (preschool and home learning environment) have different impacts depending on parental native language. The study considers 547 children from 97 German preschools. Children's vocabulary was assessed at the ages of 3, 4, and 5 years. Latent growth curve models show that non-native German language children are characterized by reduced vocabulary at first assessment and lower progress compared to monolingual peers. Phonological working memory has a strong impact on all children's initial vocabulary but also on vocabulary growth in those whose parents speak German as an additional language. The effects of preschool and home learning environment are comparatively smaller.     

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.     

Professional minutia and their consequences: provenance, context, original identification, and anthropology at the Field Museum of Natural History, Chicago, Illinois

Historical settings structure how archivists and museum staff understand their work and how they apply relevant professional principles including the three core principles of provenance, context, and original identification. Their professional practices shape how the public understands or reads “original” artifacts and records. In helping to define what originals (artifacts and documents) are at a particular point in time, archivists and museum staff reinforce, support, or contradict theoretical paradigms, discourses, and social narratives on ethnicity, empire/internal colonialism, class, and gender among others. The article discusses two exemplary cases from the museum world that illustrate how the application of the three core principles is influenced by historical conditions and theoretical concepts and how these contingent applications influence what originals come to signify. In the first example, the theoretical concept of social evolution and the World Columbian Exposition in Chicago informed the founding, collecting, describing, and displaying of American Indian objects at the Field Museum of Natural History in 1894. Reflecting this, provenance, context, and original identifications were defined to mean different things for Euro-American versus American Indian objects and records, and Native Americans and others challenged these definitions and practices at the time. In the second example, the 1929–1933 making and displaying of the Hall of Races, a specific race anthropological understanding of race created unambiguous race anthropological provenance, context and original titles (identifications) for both the exhibit and individual race sculptures. By altering information concerning the three principles over the next 60 years, the Field Museum consciously destroyed the integrity of the originals and their meanings. The exhibit had become a political liability and the museum wanted to erase any trace of the race anthropological roots of the project and its sculptures. The article ends by asserting the contingency and importance of the three core principles for archivists and museum staff regardless of the format of the material involved and adds a few related observations for our contemporary hybrid, that means physical and digital, work world.
