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.     

Computer‐based Monitoring of Rivers ‐ A Contribution to Ecological Action

Abstract

While people are beginning to know a lot about major ecological effects, little is being done individually to try to counter them. The article looks at various studies and their effects within the European Union.

     

Research in Sport Management: A Vital Rung of This New Corporate Ladder

As sport assumes greater importance in American society, research specific to the problems of this industry becomes increasingly vital. This paper reviews the current state of research in sport management. Further, four areas for future study are suggested (depending on the variables used): subordinate-related, superior-related, organization-related, and environment-related. Research topics and issues specific to each of these four areas are offered.     

Personality traits moderate the Big-Fish–Little-Pond Effect of academic self-concept

Equally able students have lower academic self-concepts in high-achieving classrooms than in low-achieving classrooms. This highly general and robust frame of reference effect is widely known as the Big-Fish–Little-Pond Effect (BFLPE; Marsh, 1987). This study contributes to research aiming to identify moderators of the BFLPE by investigating the effects of students' personality (i.e. Big Five traits and narcissism). Multilevel structural equation modeling was used to test the moderator hypotheses, drawing on data from a large sample of N = 4973 upper secondary track students (M age = 19.57). Consistent with a priori predictions, the negative effect of school-average achievement (the BFLPE) interacted significantly with narcissism. Students high in narcissism experienced smaller BFLPEs than did students with low or average levels of narcissism. The statistically significant effect for neuroticism acted in the opposite direction. The study illustrates how personality moderates frame of reference effects that are central to self-concept formation.     

Standardizing characterization of membrane active peptides with microfluidics

Antimicrobial peptides (AMPs) are emerging as important players in the fight against antibiotic resistance. In parallel, the field of microfluidics has matured and its benefits are being exploited in applications of biomimetics and standardized testing. Membrane models are essential tools extensively utilized in studying the activity and modes of action of AMPs. Here, we describe how the utilization of microfluidic platforms in characterizing membrane active peptides can develop a reliable colorful image that classical techniques have rendered black and white.     

Adventure-based experiential therapy with inpatients in child and adolescent psychiatry: an approach to practicability and evaluation

This article examines the use of adventure-based experiential therapy (AET) with child and adolescent psychiatry inpatients. AET environments, indications, practicality, therapeutic effects and research are outlined and clinical findings are reported. Activities such as rock-climbing, exploring a creek and caving are discussed and the limitations of AET in the hospital setting are addressed. AET activities range from leisure-time activities and activities that facilitate change to actual therapeutic work. Case studies showing the effects on individuals and groups, with and without specific processing of the activity, are surveyed and the similarities to mentalization-based psychotherapy are touched upon. Possible future research directions are suggested. As AET treatments are not commonly discussed in child and adolescent psychiatry, this article seeks to be a catalyst for further discussion and research.     

Reliability and agreement of student ratings of the classroom environment: A reanalysis of TIMSS data

In educational research, characteristics of the learning environment are generally assessed by asking students to evaluate features of their lessons. The student ratings produced by this simple and efficient research strategy can be analysed from two different perspectives. At the individual level, they represent the individual student’s perception of the learning environment. Scores aggregated to the classroom level reflect perceptions of the shared learning environment, corrected for individual idiosyncrasies. This second approach is often pursued in studies on teaching quality and effectiveness, where student-level ratings are aggregated to the class level to obtain general information about the learning environment. Although this strategy is widely applied in educational research, neither the reliability of aggregated student ratings nor the within-group agreement between the students in a class has been subject to much investigation. The present study introduces and discusses different procedures that have been proposed in the field of organisational psychology to assess the reliability and agreement of students’ ratings of their instruction. The application of the proposed indexes is demonstrated by a reanalysis of student ratings of mathematics instruction obtained in the Third International Mathematics and Science Study (N = 2,064 students in 100 classes).
