Enhancing Knowledge Transfer in Classroom Versus Online Settings: The Interplay Among Instructor, Student, Content, and Context

This article integrates management education and organizational learning theories to identify the factors that drive the differences in student outcomes between the online and classroom settings. We draw upon theory on knowledge transfer barriers in organizations to understand the interlinking relationships among presage conditions, deep learning process, and product in the 3P model of student learning. We test our model in the context of undergraduate education and find that confidence in the instructor's expertise, perceived content relevance, and the social richness of the classroom learning environment enhance student enjoyment of the course. Confidence in instructor's expertise and perceived content relevance also contribute to greater understanding of causal relationships among course concepts. Enjoyment is positively associated with learning performance in the classroom, but not online, and student ability is positively associated with learning performance in the online context, but not in the classroom. Our results have implications for course designs in the traditional classroom context and the more innovative online environment.     

Scaling Constraints in Junior Tennis: The Influence of Net Height on Skilled Players’ Match-Play Performance

Purpose: The net height in tennis (0.91 m) is approximately 50% of a professional tennis player’s height. Children are also expected to play with this net height, even though it is approximately 70% of the average 10-year-old’s height. This study examined the immediate effect of lowering net height on the performance characteristics of skilled junior tennis players aged 10 years and younger. Method: Sixteen players were matched in 8 pairs of even tennis ability and same sex. Each pair played 25-min singles matches in 4 conditions that varied in net height (0.91 m, 0.78 m, 0.65 m, and 0.52 m). Match-play characteristics were analyzed via video replay. Results: Results showed that lowering the net height to 0.65 m and 0.52 m led to players adopting a more attacking style of play, as evidenced by a significant increase in the number of winners without a commensurate increase in errors and more shots struck inside the baseline. Lower nets also led to a greater percentage of successful first serves. The lowest net (0.52 m), however, reduced rally length significantly and therefore decreased hitting opportunities. Conclusion: These results offer support for equipment scaling to enhance match-play performance for skilled junior tennis players. We propose that current net height recommendations for junior tennis should be revised.     

A test-retest assessment of the effects of mental load on ratings of affect,arousal and perceived exertion during submaximal cycling

This study aimed to test the effects of mental (i.e. executive) load during a dual physical-mental task on ratings of perceived exertion (RPE), affective valence, and arousal. The protocol included two dual tasks with matched physical demands but different executive demands (2-back and oddball), carried out on different days. The procedure was run twice to assess the sensitivity and stability of RPE, valence and arousal across the two trials. Linear mixed-effects analyses showed less positive valence (?0.44 points on average in a 1–9 scale; R_β² = 0.074 [CI90%, 0.052–0.098]), and heightened arousal (+0.13 points on average in a 1–9 scale; R_β² = 0.006 [CI90%, 0.001–0.015]), for the high executive load condition, but showed no effect of mental load on RPE. Separated analyses for the two task trials yielded best-fitting models that were identical across trials for RPE and valence, but not for arousal. Model fitting was improved by assuming a 1-level autoregressive covariance structure for all analyses. In conclusion, executive load during a dual physical-mental task modulates the emotional response to effort, but not RPE. The autoregressive covariance suggests that people tend to anchor estimates on prior ones, which imposes certain limits on scales' usability.

‘Discipline Your Ladies … So They Become Independent’: A Discourse on the Beginnings of Women’s Skiing in the Black Forest,Germany

Abstract

The Black Forest is considered to be the cradle of skiing in Germany. In 2016, the 125th anniversary of the beginning of skiing in the Black Forest is being celebrated. Over the decades, skiing developed into a very popular sport for men and women in Germany and spread to the Alps. Presently, the German Ski Federation (Deutscher Skiverband, DSV) has over 500,000 members, about 40% being women. This paper will concentrate on the first decades of women’s skiing in the Black Forest until the First World War. To present a wider picture, in some sections, it will be necessary to relate to other parts of Germany. A special focus will be put on competitive skiing, skiing as a social event and the discourse about women’s ski clothes.     

Evaluation of farmer participatory extension programmes

Purpose: Participatory extension programmes are widely used to promote change in the agricultural sector, and an important question is how best to measure the effectiveness of such programmes after implementation. This study seeks to understand the current state of practice through a review of ex post evaluations of participatory extension programmes.

Design/methodology/approach: A systematic literature review of the peer-reviewed literature was undertaken to analyse the evaluations based on: (i) year of publication; (ii) location of the study; (iii) programme delivery; (iv) evaluation methods; (v) outcome variables; and (vi) inclusion of evaluation in initial programme design.

Findings: The review finds that almost all studies use an experimental or quasi-experimental research design (i.e. using a control group or counterfactual), but some studies do not account for endogeneity or selection bias. Furthermore, only a small number of the evaluations were planned as part of the original programme design, which causes difficulties in obtaining robust counterfactuals. The review also finds that relatively few evaluations, approximately 20%, measure the programme impact on environmental outcomes and only 15% of the evaluations have been undertaken for programmes in developed countries.

Practical implication: Limitations with current evaluation practice are identified, and recommendations are provided for improving practice, including better treatment of endogeneity, and the complementary use of qualitative data.

Theoretical implication: The review provides a contribution to the debate about the use of quantitative versus qualitative evaluation methods, by addressing the use of both quantitative and qualitative evaluation methods in a complementary way.

Originality/value: Despite their widespread implementation, this is the first systematic literature review for published evaluations of participatory extension programmes in the agricultural sector.     

Effects of Visual and Phonological Distinctness on Visual–verbal Paired Associate Learning in Dutch Dyslexic and Normal Readers

In three studies, the effects of visual and phonological distinctness on the visual–verbal paired associate learning of dyslexic and normal readers at the age of 10–12 were examined. We hypothesized that both groups would be equally affected by the visual distinctness of the pictures, whereas the learning performance of the dyslexic children would be more susceptible to the phonological distinctness of the verbal stimuli (words). As expected, in Study 1 we found that the visual distinctness of pictures had a similar effect on both groups. However, the results of Studies 2 and 3 on the effect of phonological distinctness did not support the hypothesis. Both reader groups were equally affected by the phonological distinctness of the words. In addition, we found that, although not consistently, dyslexic children tended to be worse in verbal learning, which could to a large extent be explained by their problems with phonological processing.     

Peer Problems and Hyperactivity–Impulsivity Among Norwegian and American Children: The Role of 5‐HTTLPR

Peer problems are linked to attention deficit hyperactivity disorder (ADHD) symptoms and the serotonin system is thought to be involved in ADHD‐related behavior. Hence, from a Gene × Environment perspective, the serotonin transporter 5‐HTTLPR may play a moderating role. In two large community samples, the moderating role of 5‐HTTLPR was examined related to more hyperactivity–impulsivity symptoms (HI symptoms) predicted by more peer problems. In Study 1, involving 642 Norwegian children, results indicated that for s‐allele carriers only, caregiver‐reported peer problems at age 4 predicted more parent‐reported HI symptoms at age 6. In Study 2, similar results emerged involving 482 American children. Discussion focuses on differential sensitivity to the adverse effects of poor peer relations.     

Information and Digital Literacies in a Kindergarten Classroom: An I-LEARN Case Study

This case study, part of a larger qualitative research project, involved 24 kindergarteners and their teacher in the design, development, and evaluation of a research project built around the I-LEARN model (Neuman, Learning in information-rich environments: I-LEARN and the construction of knowledge in the 21st Century. Springer, New York, 2011b). I-LEARN is a six-step learning model (Identify, Locate, Evaluate, Apply, Reflect and kNow) designed to guide research for twenty first-century learning. The objectives of the study were both to improve the digital and information literacies of the participants and to validate the I-LEARN model for use in an early childhood classroom. The findings have implications for information literacy, digital literacy, and developmentally appropriate practices.
