The Effectiveness of Collaborative Augmented Reality in Gross Anatomy Teaching: A Quantitative and Qualitative Pilot Study

In the context of gross anatomy education, novel augmented reality (AR) systems have the potential to serve as complementary pedagogical tools and facilitate interactive, student-centered learning. However, there is a lack of AR systems that enable multiple students to engage in collaborative, team-based learning environments. This article presents the results of a pilot study in which first-year medical students (n = 16) had the opportunity to work with such a collaborative AR system during a full-day gross anatomy seminar. Student performance in an anatomy knowledge test, conducted after an extensive group learning session, increased significantly compared to a pre-test in both the experimental group working with the collaborative AR system (P < 0.01) and in the control group working with traditional anatomy atlases and three-dimensional (3D) models (P < 0.01). However, no significant differences were found between the test results of both groups. While the experienced mental effort during the collaborative learning session was considered rather high (5.13 ± 2.45 on a seven-point Likert scale), both qualitative and quantitative feedback during a survey as well as the results of a System Usability Scale (SUS) questionnaire (80.00 ± 13.90) outlined the potential of the collaborative AR system for increasing students' 3D understanding of topographic anatomy and its advantages over comparable AR systems for single-user experiences. Overall, these outcomes show that collaborative AR systems such as the one evaluated within this work stimulate interactive, student-centered learning in teams and have the potential to become an integral part of a modern, multi-modal anatomy curriculum.     

The German Media Start-up Opinary: Inventing Tools for Readers’ Opinion-Sharing Online—Reinventing User Engagement on News Websites

Users of news websites increasingly desire to state their opinion on a current issue discussed online. The usual way to do so is writing a comment. However, only few people make use of the comment section and some newsrooms cannot afford to keep it permanently open. The German media start-up Opinary develops visual interactive tools trying to change the way users share opinions. Its founders want to make a new form of user engagement possible.     

Biomechanics of elite recumbent handcycling: a case study

In the presented research, a kinematic and electromyographic study was performed on one world-class male elite handbiker (UCI class H3.2). Activity of 14 muscles of the upper body were measured with surface electromyography (EMG), and a motion analysis of the athlete’s movement was performed concurrently for different backrest positions, crank lengths, and crank heights at three power levels (130, 160 and 190 W). Kinematics in terms of elbow and wrist angle, muscular on-off timing, EMG amplitudes, and integrated EMG were calculated. Results showed that little changes occurred for kinematic parameters and changes in position led to a shift in muscular timing. However, no indication for immediate improvement to the athlete’s preferred original position could be observed.     

Der Zusammenhang von Schulleitungshandeln,Unterrichtsgestaltung und Lernerfolg

Indicators and instruments for determining and measuring school quality within inspection systems are usually based on frameworks for inspection. These frameworks rely heavily upon school and teacher effectiveness research. Thus, a central assumption is that the effectiveness and improvement-oriented school conditions, as measured within an inspection, are related to student achievement. It is unclear if this assumption really holds true, as empirical evidence is still lacking. This study uses data from a random sampling of schools (n = 37) and teachers (n = 1663) and the achievement data from students (n = 23,943) to validate the interpretations and uses of school inspection results regarding the factor school leadership. The study follows Kane’s argument-based approach for validation. Results reveal that principals of schools with recurrent high student achievement very often demonstrate instructional leadership. It is evident that these principals are also leading in a fundamentally different way from principals in schools with lower achievement in that they lead with the specific school context in mind. The study demonstrates that it is possible to make inferences from scores provided by school inspections and to generalize from them. However, this generalizability does not extend to making extrapolations or decisions based on these scores. The analyses make it clear that providing feedback solely on the strengths and weakness of a school is insufficient when it comes to stimulating school improvement through inspection.     

Cross-cultural comparisons of child-reported emotional and physical abuse: rates, risk factors and psychosocial symptoms

OBJECTIVES: This study was designed to assess the incidence of child emotional and physical abuse, associated risk factors and psychosocial symptoms in a cross-cultural comparison between post-communist bloc countries. Method: One-thousand one-hundred forty-five children ages 10-14 from Latvia (N = 297), Lithuania ( N = 300), Macedonia (N = 302), and Moldova (N = 246) participated in the study. They completed questionnaires assessing their experience of emotional or physical abuse, and provided information about family risk-factors and psychosocial symptoms, including PTSD-related symptoms. RESULTS: Incidence rates of maltreatment differed by country, as did levels of reported psychosocial symptoms. Incidence of emotional and physical abuse differed by region, with higher levels of abuse reported in the rural regions. In all four countries, a similar association between emotional/physical abuse and psychosocial symptoms was found, with the uniformly largest correlation between emotional abuse and anger. When examining the combined scores of emotional and physcial abuse, even higher correlation's were found, particularly in relation to anger and depression. In all four countries, parental overuse of alcohol was associated with emotional and/or physical abuse. CONCLUSIONS: Findings show differences by country in child-reported levels of emotional and physical abuse, but similar patterns of correlation with psychosocial symptoms and the risk factors of parental alcohol overuse and living in a rural area.     

Value orientations and action conflicts in students’ everyday life: An interview study

The assumption that today’s German students are able to successfully combine synthesis achievement values and well-being values appears to be overly optimistic when regarded from the perspective of motivational psychology. The results of a qualitative-quantitative interview study with 25 students indicate that achievement and well-being values may come into conflict in everyday life. Incentives for achievement and well-being rarely co-occur in the same action domains. Whereas the school context is dominated by achievement incentives, leisure time is dominated by well-being incentives. Since both achievement and well-being are appreciated by most students, they should be prone to experience frequent everyday action conflicts. The motivational characteristics of postdecisional action conflicts are described on the phenomenal level and their possible impairing effects for learning processes are pointed out. Finally, alternative forms of value synthesis, which might be realized more successfully, are discussed.     

Drawing digital pictures: An investigation of primary pupils’ representations of ICT and schools

The relatively restricted nature of children's use of information and communications technologies (ICTs) inside the school setting has long been noted by researchers. With this in mind, this article offers a grounded analysis of drawings collected from 355 primary pupils (years three to six) from five English primary schools depicting desired future forms of school ICT provision. The article contends that the nature and content of these future orientated pictures reflect many of the tensions underlying children's current engagements with ICTs in school. Specifically the article discusses how the drawings offer valuable insights into the issues underlying pupils’ understandings of ICT and schools, not least: the restrictions of the school as organisation; the oppositional relationship between the ‘work’ of learning in school and the ‘play’ of using digital media at home; the unequal power relations that exist between pupils, schools and teachers. The article concludes that rather than accede to demands for free and unfettered use of game consoles and portable devices in the classroom, schools should instead concentrate on fostering informed dialogues with young people about the potential educational benefits of school ICT use.     

Seriously Entertained: Antecedents and Consequences of Hedonic and Eudaimonic Entertainment Experiences With Political Talk Shows on TV

This study's purpose is twofold: to introduce a new format into existing political entertainment research (“serious” political talk shows) and to establish a more specific definition of entertainment in a political context. To do so, the authors rely on a two-process-model of entertainment experiences. A telephone survey (N = 230) was conducted to analyze the antecedents and consequences of eudaimonic and hedonic entertainment experiences and to look into politically relevant variables and their distribution among viewers and nonviewers of such talk shows. The results highlight the importance of introducing new entertainment concepts and their relations to other relevant political and motivational variables into the research of political entertainment. More specifically, the findings demonstrate how entertainment experiences contribute to viewers' feeling of being informed and point out several differences between viewers and nonviewers concerning their internal political efficacy and political interest. Finally, looking at political talk shows from an audience perspective extends previous content-based taxonomies.
