Effectiveness of a Short,Intense Bridging Course for Scaffolding Students Commencing University-level Study of Chemistry

Bridging courses designed to support students commencing tertiary education are widespread, and some evidence for the value of semester-length courses has been reported; however, little attention has been paid to short-but-intense bridging courses, and empirical evidence of their effectiveness is particularly sparse. The current study followed the academic performance of a cohort of students enrolled in a first-year chemistry unit of study designed for those with little or no background knowledge of chemistry. The aims of this study are two-fold: first to determine the strength of the linkage between prior knowledge in chemistry and performance on the end of semester exam, and secondly, to explore the reasons for any differences observed. In particular, the value of the week-long intensive-mode bridging course offered by the University of Sydney was analysed. Quantitative and qualitative data were collected. The research has shown that participation in the chemistry bridging course is associated with ‘bridging the gap’ in academic performance between students with No Prior Chemistry background and those with a Strong Background. While the content of the bridging course is a significant contributor to academic success, so too is the confidence in their own learning that the course engenders among participants.     

Service Blueprinting: A Method for Assessing Library Technologies within an Interconnected Service Ecosystem

ABSTRACT

Service blueprinting is a method for designing, assessing, and improving services. This article provides a practical overview of the service blueprinting process for library technology services. We begin by outlining the recent conversation around library technologies, service design, and service blueprinting. We then detail an iterative case study for the creation process of a service blueprint, followed by a discussion of the service insights and improvements that resulted from this activity. We conclude by offering a set of recommendations for creating and analyzing service blueprints. Ultimately, the service blueprint is a useful tool for understanding the operation of a service, and for situating that service within a broader and interconnected library ecosystem.     

Family‐Centered Positive Behavior Support Interventions in Early Childhood To Prevent Obesity

Positive behavior support (PBS) strategies in early childhood, which include proactively structuring environments to support and positively reinforce healthy dietary and physical activity behaviors, are critical for preventing pediatric obesity, particularly among low‐income, ethnic minority children. Existing evidence‐based family‐centered preventive interventions effectively impact parents’ use of PBS strategies. Enhancing these programs to more directly target the key mechanisms of change specific to promoting children's healthy lifestyle behaviors could serve as the foundation for the next generation of effective protocols for preventing pediatric obesity. Two established programs that target PBS that can be feasibly implemented in a variety of service delivery systems using a multi‐tiered, adaptive approach and the next steps of translation are discussed.     

Factor structure of child behavior scale scores in peruvian preschoolers

Behavior rating scales aid in the identification of problem behaviors, as well as the development of interventions to reduce such behavior. Although scores on many behavior rating scales have been validated in the United States, there have been few such studies in other cultural contexts. In this study, the structural validity of scores on a Spanish translation of the six‐factor Child Behavior Scale (CBS) was assessed in a sample of 265 Peruvian preschool children who ranged from 2 to 6 years in age. Exploratory factor analysis yielded a four‐factor structure, and reliability estimates for scores on the four factors were adequate. The authors suggest replicating the study and examining the utility of CBS scores in predicting future problem behaviors in this population. © 2011 Wiley Periodicals, Inc.     

Three-Dimensional Printing of Archived Human Fetal Material for Teaching Purposes

The practical aspect of human developmental biology education is often limited to the observation and use of animal models to illustrate developmental anatomy. This is due in part to the difficulty of accessing human embryonic and fetal specimens, and the sensitivity inherent to presenting these specimens as teaching materials. This report presents a new approach using three-dimensional (3D) printed replicas of actual human materials in practical classes, thus allowing for the inclusion of accurate examples of human developmental anatomy in the educational context. A series of 3D prints have been produced from digital data collected by computed tomography (CT) imaging of an archived series of preserved human embryonic and fetal specimens. The final versions of 3D prints have been generated in a range of single or multiple materials to illustrate the progression of human development, including the development of internal anatomy. Furthermore, multiple copies of each replica have been printed for large group teaching. In addition to the educational benefit of examining accurate 3D replicas, this approach lessens the potential for adverse student reaction (due to cultural background or personal experience) to observing actual human embryonic/fetal anatomical specimens, and reduces the potential of damage or loss of original specimens. This approach, in combination with ongoing improvements in the management and analysis of digital data and advances in scanning technology, has enormous potential to allow embryology students access to both local and international collections of human gestational material.

An attention-modulated associative network

We present an elemental model of associative learning that describes interactions between stimulus elements as a process of competitive normalization. Building on the assumptions laid out in Harris (2006), stimuli are represented as an array of elements that compete for attention according to the strength of their input. Elements form associations among each other according to temporal correlations in their activation but restricted by their connectivity. The model moves beyond its predecessor by specifying excitatory, inhibitory, and attention processes for each element in real time and describing their interaction as a form of suppressive gain control. Attention is formalized in this model as a network of mutually inhibitory units that moderate the activation of stimulus elements by controlling the level to which the elements are suppressed by their own inhibitory processes. The model is applied to a range of complex discriminations and related phenomena that have been taken as evidence for configural-learning processes.     

Comparative efficacy of group and individual feedback in gross anatomy for promoting medical student professionalism

Professionalism is a core competency of medical training that requires students to develop the skills of providing and receiving feedback. Our study evaluated the effectiveness of delivering feedback in a group setting compared with an individual setting. The first‐year class of Mayo medical students (n = 49) enrolled in gross anatomy (in dissection teams), completed weekly anonymous evaluations of themselves and their teammates regarding seven aspects of professionalism (altruism, compassion, respect, honesty/integrity, responsibility, commitment to excellence, and self‐reflection). Professionalism scores from these surveys were calculated using a six‐point Likert scale. Students were also asked to comment on strengths and possible areas for improvement on each peer. At the midpoint of the course, peer comments and professionalism scores were shared with students in debriefing sessions either individually or with their team. Analysis of preintervention and postintervention professionalism scores indicated that the students receiving feedback in a one‐on‐one setting (student and instructor) were more likely to demonstrate higher scores on subsequent evaluations as compared with those students receiving feedback in a group setting (all team members and one instructor). Our findings suggest that providing feedback to first‐year medical students on an individual basis is the best way to improve professional attitudes and behaviors.

The influence of hydration on anaerobic performance: a review

This review examines the influence of dehydration on muscular strength and endurance and on single and repeated anaerobic sprint bouts. Describing hydration effects on anaerobic performance is difficult because various exercise modes are dominated by anaerobic energy pathways, but still contain inherent physiological differences. The critical level of water deficit (approximately 3-4%; mode dependent) affecting anaerobic performance is larger than the deficit (approximately 2%) impairing endurance performance. A critical performance-duration component (> 30 s) may also exist. Moderate dehydration (approximately 3% body weight; precise threshold depends on work/recovery ratio) impairs repeated anaerobic bouts, which place an increased demand on aerobic metabolism. Interactions between dehydration level, dehydration mode, testing mode, performance duration, and work/recovery ratio during repeated bouts make the dehydration threshold influencing anaerobic performance mode dependent.
