This study employs narrative methods to give a holistic view of the experiences of five mature age preservice teachers in
a semester unit of science education. The unit was designed to help teachers examine and make explicit their ideas about science
and science teaching and consider ways in which they might put those ideas into practice. The pivotal theme, around which
the teachers' experiences could be organised, was found to be learning science. The preservice teachers expressed a need for
a supportive learning environment in which concepts were built gradually and introduced using concrete examples. Previous
science experience was found to be a major influence on the attitudes the participants brought to the present course. A lack
of previous experience or negative past experiences were a major cause of anxiety. Gender was also important as it had limited
the science experiences available to some participants in the past and continued to influence the way they participated in
classes during the semester.

A study of students from a primary school and its local secondary school was conducted to investigate students' relative interests
in geology and biology during the years prior to Year 10. Students from Years 1, 3, 5, 7 and 9 were interviewed, using an
innovative interview technique, and results show that interest in both subjects appears to be fairly evenly distributed throughout
all years. This paper reports on the study conducted and illustrates the success of the interview technique developed to accommodate
all students, especially those from younger year levels.

Purpose: The benefits of physical activity (PA) in preventing abdominal obesity are well recognized, but the role of different sport disciplines remains open. We aimed, therefore, to investigate how participation in different sport disciplines, and the number and types of sports engaged in are associated with waist circumference (WC) in young adulthood. Methods: This population-based cohort study comprised 4027 Finnish twin individuals (1874 men), with a mean age of 34 y (32–37), who answered a survey, including self-measured WC. We extracted the number and identified the types (aerobic, power, and mixed) of the different sport disciplines respondents reported participating in. Results: The number of sport disciplines participated in was inversely associated with WC, the linear decrease averaging 1.38?cm (95% CI 1.10–1.65) per each additional sport discipline. The result persisted after adjustment for the main covariates, such as volume of PA and diet quality. Among dizygotic twin pairs discordant for sports participation (0–2 vs. 5 or more disciplines), the mean within-pair difference in WC was 4.8?cm (95% CI 0.4–9.1) for men and 11.2?cm (95% CI 4.4–18.0) for women; among discordant monozygotic pairs, no differences were observed. In men, all three types of sports were individually associated with smaller WC, while in women, only mixed and power sports showed this association. Conclusions: Participation in several sport disciplines and sport types was associated with smaller WC among young adults in their mid-30s. Shared genetic background may explain some of the associations. 相似文献

Test procedures and their accuracy in determining critical fall height (CFH) on sporting grounds are paramount to player safety.
The procedure currently adopted for synthetic turf in Australian football [1] consists of four consecutive drops at various drop heights at three test locations on the sample. The quantity and packing
of the infill in third-generation turf and the pooling effect of the rubber particles with consecutive drops suggests that
the current standard protocol may need re-assessment. Therefore, the purpose of this pilot study was to investigate whether
current methods of testing for CFH are appropriate for third-generation synthetic turf or whether an alternative or adapted
method needs to be developed. CFH was measured, using a HISUN Uniaxe-II Impact Tester, on 12 combinations of synthetic turf
samples (four different products with three shock pad options). Three conditions were investigated on each sample; the existing
protocol; an alternative 12 single-drop protocol and four single drops from the CFH determined from the existing protocol.
A significant difference was found for both absolute and percentage difference between the existing and 12 single-drop protocol,
with p = 0.001 and t = 4.33 and p < 0.001 and t = 6.03, respectively. There was also a significant difference between the CFH reached with and without a shock pad for both
the existing protocol and the 12 single-drop protocol. The results of this pilot study demonstrate that differences do occur
with alterations to the existing protocol and highlight the need for a more detailed characterisation of testing methods on
third-generation synthetic turf and the response of surfaces to them. 相似文献

Central Michigan University provides, through the Individualized Degree Program, a bachelor's degree to individuals who could not be served by conventional on-campus programs. The present study was undertaken in an effort to learn more about selected attributes of those in the program. Quantitative and qualitative analyses of the data revealed characteristics common to participants in the Individualized Degree Program and isolated five factors which are predictive of academic success. 相似文献
