Enhancement of anatomical learning and developing clinical competence of first‐year medical and allied health profession students

Hands‐on educational experiences can stimulate student interest, increase knowledge retention, and enhance development of clinical skills. The Lachman test, used to assess the integrity of the anterior cruciate ligament (ACL), is commonly performed by health care professionals and is relatively easy to teach to first‐year health profession students. This study integrated teaching the Lachman test into a first‐year anatomy laboratory and examined if students receiving the training would be more confident, competent, and if the training would enhance anatomical learning. First‐year medical, physician assistant and physical therapy students were randomly assigned into either the intervention (Group A) or control group (Group B). Both groups received the course lecture on knee anatomy and training on how to perform the Lachman test during a surface anatomy class. Group A received an additional 15 minutes hands‐on training for the Lachman test utilizing a lightly embalmed cadaver as a simulated patient. One week later, both groups performed the Lachman test on a lightly embalmed cadaver and later completed a post‐test and survey. Students with hands‐on training performed significantly better than students with lecture‐only training in completing the checklist, a post‐test, and correctly diagnosing an ACL tear. Students in Group A also reported being more confident after hands‐on training compared to students receiving lecture‐only training. Both groups reported that incorporating clinical skill activities facilitated learning and created excitement for learning. Hands‐on training using lightly embalmed cadavers as patient simulators increased confidence and competence in performing the Lachman test and aided in learning anatomy.

The Roles of Engagement at The Ohio State University Libraries: Thoughts from an Early Adopter

Changes in information and technology continue to test how librarians interact with and support patrons. Now, engaged librarians have the opportunity to immerse themselves in their user’s workflows and become partners in the research enterprise. Engagement represents a model of librarianship in which librarians are challenged to move from the traditional collection-centered model to an engaged-focused one. It requires new roles and tasks, as well as a deeper understanding of the academic setting. This article discusses working in a large research institution and articulates the engagement model.     

A tapered channel microfluidic device for comprehensive cell adhesion analysis, using measurements of detachment kinetics and shear stress-dependent motion

We have developed a method for studying cellular adhesion by using a custom-designed microfluidic device with parallel non-connected tapered channels. The design enables investigation of cellular responses to a large range of shear stress (ratio of 25) with a single input flow-rate. For each shear stress, a large number of cells are analyzed (500–1500 cells), providing statistically relevant data within a single experiment. Besides adhesion strength measurements, the microsystem presented in this paper enables in-depth analysis of cell detachment kinetics by real-time videomicroscopy. It offers the possibility to analyze adhesion-associated processes, such as migration or cell shape change, within the same experiment. To show the versatility of our device, we examined quantitatively cell adhesion by analyzing kinetics, adhesive strength and migration behaviour or cell shape modifications of the unicellular model cell organism Dictyostelium discoideum at 21 °C and of the human breast cancer cell line MDA-MB-231 at 37 °C. For both cell types, we found that the threshold stresses, which are necessary to detach the cells, follow lognormal distributions, and that the detachment process follows first order kinetics. In addition, for particular conditions’ cells are found to exhibit similar adhesion threshold stresses, but very different detachment kinetics, revealing the importance of dynamics analysis to fully describe cell adhesion. With its rapid implementation and potential for parallel sample processing, such microsystem offers a highly controllable platform for exploring cell adhesion characteristics in a large set of environmental conditions and cell types, and could have wide applications across cell biology, tissue engineering, and cell screening.     

Differences between web sessions according to the origin of their visits

The aim of this paper is to characterize the distribution of number of hits and spent time by web session. It also expects to find if there are significant differences between the length and the duration of a session with regard to the point of access–search engine, link or root. Web usage mining was used to analyse 17,174 web sessions that were identified from the webometrics.info web site. Results show that both distribution of length and duration follow an exponential decay. Significant differences between the different origins of the visits were also found, being the search engines’ users those who spent most time and did more clicks in their sessions. We conclude that a good SEO policy would be justified, because search engines are the principal intermediaries to this web site.     

Training and psychosocial patterns during the early development of Portuguese national team athletes

This study explored the early development of expert athletes compared to a group of athletes that did not achieve an expert level of performance despite being involved in youth events with their national squads. In particular, the activities, training patterns, and psychosocial influences that characterized their paths in competitive sports were examined. Male and female participants (N?=?42) from different sports were interviewed. Overall, athletes showed several commonalities. However, experts were selected to national squads later and also started thinking about investing in becoming elite athletes later. Non-experts revealed more parental pressure and less individual training with coaches.     

Mentoring Matters: An Exploratory Survey of Educational Leadership Doctoral Students’ Perspectives

There is limited research on quantitative differences between men and women’s experiences in doctoral programs. We aim to fill that gap by sharing findings from a web-based exploratory survey of perceived gender differences on quality mentoring in educational leadership doctoral programs. According to survey results, there is limited statistical significance in terms of gender differences in programmatic supports and scholarly progress. However, women experience feelings of self-doubt due to negative experiences with advising and mentoring, including difficulties making connections to a quality mentor. Furthermore, both female and male participants shared common definitions of what constitutes quality mentorship and believed mentorship was important, but lacking in varying degrees. Finally, all participants agreed that their educational leadership preparation programs should provide additional support in terms of writing and research development. Participants also shared important recommendations for strengthening mentoring experiences as well as future research methods and foci.     

Effects of a Cooperative Learning Program on the Elaborations of Students Working in Dyads

In this study, the effects of a school improvement program on cooperative learning (CL) with respect to the elaborations of 6th-grade students working in mixed-ability and mixed-sex dyads on 2 cooperative tasks were examined. A posttest-only design with a control group was used to investigate the provision and receipt of elaborations within the dyads and the performance of the dyads working on cooperative mathematics and language tasks. Treatment dyads were found to exchange significantly more high-level elaborations during the language task than the control dyads. The treatment dyads also tended to produce higher performance scores on the 2 tasks.     

National Assessment of New Standards for Mathematics in Elementary Education in Flanders

A baseline assessment of the new curriculum standards of mathematics for elementary education in Flanders is presented and discussed. A total of 24 measurement scales, each representing a cluster of standards, covered the whole mathematics curriculum. A total of 5,763 6th-grade students participated in the study. Performance on each scale was summarized by estimating the proportion of students who were nonmasters, intermediate, and good masters. Overall, the more innovative curriculum standards were mastered worse. Few gender differences in performance were observed.
