How much anatomy is enough?

Innovations in undergraduate medical education, such as integration of disciplines and problem based learning, have given rise to concerns about students' knowledge of anatomy. This article originated from several studies investigating the knowledge of anatomy of students at the eight Dutch medical schools. The studies showed that undergraduate students uniformly perceived deficiencies in their anatomical knowledge when they started clinical training regardless of their school's didactic approach. A study assessing students' actual knowledge of clinical anatomy revealed no relationship between students' knowledge and the school's didactic approach. Test failure rates based on absolute standards set by different groups of experts were indicative of unsatisfactory levels of anatomical knowledge, although standards differed markedly between the groups of experts. Good test performance by students seems to be related to total teaching time for anatomy, teaching in clinical context, and revisiting anatomy topics in the course of the curriculum. These factors appeared to outweigh the effects of disciplinary integration orwhether the curriculum was problem‐based or traditional.

Wireless instrumented klapskates for long-track speed skating

In the current project, we aim to provide speed skaters with real-time feedback on how to improve their skating performance within an individual stroke. The elite skaters and their coaches wish for a system that determines the mechanical power per stroke. The push-off force of the skater is a crucial variable in this power determination. In this study, we present the construction and calibration of a pair of wireless instrumented klapskates that can continuously and synchronously measure this push-off force in both the lateral direction and normal direction of the skate and the centre of pressure of these forces. The skate consists of a newly designed rigid bridge (0.6 kg), embedding two three-dimensional force sensors (Kistler 9602, Kistler Group, Winterthur, Switzerland), which fits between most individual skate shoes and Maple skate blades. The instrumented klapskates were calibrated on a tensile testing machine, where they proved to be unaffected to temperature conditions and accurate up to an RMS of 42 N (SEM = 1 N) in normal and up to an RMS of 27 N (SEM = 1 N) in lateral direction. Furthermore, the centre of pressure of these forces on the blade was determined up to a mean error of 10.1 mm (SD = 6.9 mm). On-ice measurements showed the possibility of recording with both skates simultaneously and synchronously, straights as well as curves. The option to send data wirelessly and real-time to other devices makes it possible to eventually provide skaters and coaches with visual real-time feedback during practice.     

Institutional Level Student Engagement and Organisational Cultures

Driven by the growing presence of market forces within higher education worldwide, universities are changing the way they engage with students. This article explores how a university's internal culture relates to engagement with students and their views. It builds on wider research into student engagement and organisational cultures. The organisational cultures of two universities are mapped against a typology developed by McNay, which was extended by the author to include aspects of institutional engagement with students. It appears that corporate and bureaucratic institutional cultures that may respond well to external pressures on institutions (regulation, performance indicators, audits and policy pressure) are not conducive to engagement with student opinion. The stronger preference of students remains a collegial, partnership‐based approach for enhancement of the student experience. This study will be of interest to institutional managers, student (union) leaders, academics and practitioners who seek to improve the student experience through effective engagement with student views.     

Effects of Montessori Education on the Academic,Cognitive, and Social Development of Disadvantaged Preschoolers: A Randomized Controlled Study in the French Public-School System

Previous research on Montessori preschool education is inconsistent and prone to analytic flexibility. In this preregistered study, disadvantaged preschoolers in a French public school were randomly assigned to either conventional or Montessori classrooms, with the latter being adapted to French public education. Adaptations included fewer materials, shorter work periods, and relatively limited Montessori teacher training. Cross-sectional analyses in kindergarten (N = 176; M_age = 5–6) and longitudinal analyses over the 3 years of preschool (N = 70; M_age = 3–6) showed that the adapted Montessori curriculum was associated with outcomes comparable to the conventional curriculum on math, executive functions, and social skills. However, disadvantaged kindergarteners from Montessori classrooms outperformed their peers on reading (d = 0.68). This performance was comparable to that of advantaged children from an accredited Montessori preschool.     

Who succeeds in advanced mathematics and science courses?

Few students (particularly few girls) currently choose to take their Final School Examination (FSE) in advanced mathematics, chemistry and physics, a combination of subjects that is the best preparation for a science‐oriented study in higher education. Are these subjects attainable by more students than is currently the case? This study examined 6033 students in upper secondary education, including 720 students who took their FSE in advanced mathematics, chemistry and physics. The results show that the latter group (and in particular the girls in that group) had higher scores on math ability than students who chose other examination subjects. Regression analyses demonstrated the relative importance of math ability and achievement motivation for attainment in these science subjects. However, an expected positive effect of homework time as well as possible mediating and moderating effects of the predictors could not be confirmed.     

Development and validation of a low cost blood filtration element separating plasma from undiluted whole blood

Clinical point of care testing often needs plasma instead of whole blood. As centrifugation is labor intensive and not always accessible, filtration is a more appropriate separation technique. The complexity of whole blood is such that there is still no commercially available filtration system capable of separating small sample volumes (10-100 μl) at the point of care. The microfluidics research in blood filtration is very active but to date nobody has validated a low cost device that simultaneously filtrates small samples of whole blood and reproducibly recovers clinically relevant biomarkers, and all this in a limited amount of time with undiluted raw samples. In this paper, we show first that plasma filtration from undiluted whole blood is feasible and reproducible in a low-cost microfluidic device. This novel microfluidic blood filtration element (BFE) extracts 12 μl of plasma from 100 μl of whole blood in less than 10 min. Then, we demonstrate that our device is valid for clinical studies by measuring the adsorption of interleukins through our system. This adsorption is reproducible for interleukins IL6, IL8, and IL10 but not for TNFα. Hence, our BFE is valid for clinical diagnostics with simple calibration prior to performing any measurement.
