Acceleration: A coat of many colours

The word “acceleration” continues to generate controversy. Although the literature makes it clear that acceleration in its various guises is a positive intervention for many gifted students, educational practitioners in Australia continue to resist the evidence and campaign actively against allowing students to take this option. This article synthesizes 3 research projects conducted in New South Wales, Australia, exploring different forms of acceleration. The first project involved an investigation of the Early Entry policy for gifted children in one region of the state; the second reports on the experiences of students who skipped at least 1 grade; and the third examines a vertical programming system that allows students to accelerate within subjects at an academically selective high school. Based on these research studies, this article explores the issues that are at the center of the acceleration debate.     

Informationist programme in support of biomedical research: a programme description and preliminary findings of an evaluation

BACKGROUND: The informationist programme at the Library of the National Institutes of Health (NIH) in Bethesda, MD, USA has grown to 14 informationists working with 40 clinical and basic science research teams. PURPOSE: This case report, intended to contribute to the literature on informationist programmes, describes the NIH informationist programme, including implementation experiences, the informationists' training programme, their job responsibilities and programme outcomes. BRIEF DESCRIPTION: The NIH informationist programme was designed to enhance the library's service capacity. Over time, the steps for introducing the service to new groups were formalized to ensure support by leadership, the team being served and the library. Job responsibilities also evolved from traditional library roles to a wide range of knowledge management activities. The commitment by the informationist, the team and the library to continuous learning is critical to the programme's success. RESULTS / OUTCOMES: NIH scientists reported that informationists saved them time and contributed to teamwork with expert searching and point-of-need instruction. Process evaluation helped refine the programme. EVALUATION METHOD: High-level, preliminary outcomes were identified from a survey of scientists receiving informationist services, along with key informant interviews. Process evaluation examined service implementation, informationists' training and service components. Anecdotal evidence has also indicated a favourable response to the programme.     

Problem-based medical education: effect on library use.

Problem-based learning (PBL) is being adopted by U.S. medical schools. Information-seeking skills are central to the PBL curriculum, which emphasizes self-directed learning and the acquisition of problem-solving and lifelong learning skills. The purpose of this study is to begin exploring the relationship between the PBL curriculum and student information and library use. Medical students in PBL and conventional medical school curricula were compared on library and information-seeking competencies, behaviors, and perceptions. A survey was sent to second-year students in four medical schools, two schools with two curricular tracks (one PBL and one conventional), one PBL school, and one conventional school. The results showed certain significant differences (P less than 0.05) between PBL and conventional curriculum students, suggesting that PBL students were the more frequent library users, used information resources that supported the independent learning process, acquired information-seeking skills at an earlier stage in their medical education, and reported greater ease in using these skills.     

A three-dimensional examination of the planar nature of the golf swing

Previous planar models of the downswing in golf have suggested that upper limb segments (left shoulder girdle and left arm) move in a consistent fixed plane and that the clubhead also moves only in this plane. This study sought to examine these assumptions. Three-dimensional kinematic analysis of seven right-handed golfers of various abilities (handicap 0- 15) was used to define a plane (named the left-arm plane) containing the 7th cervical vertebra, left shoulder and left wrist. We found that the angles of this plane to the reference horizontal z axis and target line axis (parallel to the reference x axis) were not consistent. The angle to the horizontal z axis varied from a mean of 133 degrees (s = 1 degrees) at the start of the downswing to 102 degrees (s = 4 degrees) at impact, suggesting a "steepening" of the left-arm plane. The angle of the plane to the target line changed from - 9 degrees (s = 16 degrees) to 5 degrees (s = 15 degrees) during the same period, showing anticlockwise (from above) rotation, although there was large inter-individual variation. The distance of the clubhead from the left-arm plane was 0.019 m (s = 0.280 m) at the start at the downswing and 0.291 m (s = 0.077 m) at impact, showing that the clubhead did not lie in the same plane as the body segments. We conclude that the left arm and shoulder girdle do not move in a consistent plane throughout the downswing, and that the clubhead does not move in this plane. Previous models of the downswing in golf may therefore be incorrect, and more complex (but realistic) simulations should be performed.
