An eight‐year study of online lecture use in a medical gross anatomy and embryology course

Online lectures have been used in lieu of live lectures in our gross anatomy and embryology course for the past eight years. We examined patterns of online lecture use by our students and related that use to academic entry measures, gender and examination performance. Detailed access records identified by student were available from server logs. Total views per page of lecture material increased over the first six years, then decreased markedly between years seven and eight, possibly due to the recent availability of alternate forms of lecture audio. Lecture use peaked in midafternoon and again in the evening, although some use was seen at all hours. Usage was highest at midweek and lowest on Fridays as might be expected. Individual student's use varied widely from rates equivalent to less than one viewing/page to more than three viewings per page. Overall use by male students was greater than that of females and gender‐specific differences in the daily pattern were seen. Lecture use was correlated to the Medical College Admission Test® (MCAT®) Verbal Reasoning and Physical Sciences scores but not to composite MCAT scores or undergraduate grade point average. Overall use appeared to be driven by scheduled team‐based learning (TBL) sessions and major examinations. Specific subsets of lecture material were most often viewed before related TBL sessions and again during review for examinations. A small but significant correlation between lecture use and examination and course performance was seen, specifically in the male student population. These findings, along with earlier observations, suggest that varied use of online lectures is attributable to multiple factors. Anat Sci Educ © 2012 American Association of Anatomists.     

Human performance modeling: A case study

Modeling critical performance elements can assist the human performance technology practitioner in better understanding the often complex, messy, and fuzzy real world of human performance. As illustrated in the embedded case study, generically developed models that, in turn, can be adapted to context‐specific applications often have the greatest practical value. The key in developing any good model is to first identify those key variables—the critical few—that truly account for the greatest variance in performance.     

Reading,learning and enacting: interpretation at visitor sites in the Wet Tropics rainforest of Australia

The northern Wet Tropics rainforest of Australia was declared a world heritage site in 1988 and now supports an extensive tourism industry that attracts an estimated 2.5 million local and international visits annually. As part of the visitor experience, many sites include both environmental and cultural interpretation experiences, which range from static displays to one‐on‐one guided tours. This paper identifies visitor demand and level of satisfaction with the static signage and displays used at rainforest sites throughout the Wet Tropics. The research involves visitor surveys conducted in 2007 and 2008 and observations at a number of rainforest sites. The results indicate that visitors consider the level of interpretation to be adequate, but appear to use it poorly. While higher at commercial sites, visitor interest in reading the interpretation is very low at public sites. Overall, this article seeks to address whether the aims of nature‐based interpretation, including education and the influencing of attitudes and site behaviour, are being achieved.     

Classroom Provocateurs and Ethical Classroom Practice

This article is based upon a larger study that considered three high school literature units in the US. Through a close analysis of one classroom discussion between a teacher and a provocative 8th grade student named Fish, I argue that it is not only ethically responsible to position the Fishes of this world as laudable, but that doing so is beneficial for critically focused English classes as a whole. Further, I argue that my reading of Fish as a provocateur can be productively transferred to other student‐provocateurs in our English classrooms who vex the smooth doing‐of‐school in different ways than Fish did.     

Attachment Styles,Social Skills,and Depression in College Women

Attachment styles, social skills, and depression were studied in 93 college women using the Relationship Questionnaire (K. Bartholomew & L. M. Horowitz, 1991), the Beck Depression Inventory‐II (A.T. Beck, R.A. Steer, & G. K. Brown, 1996), and the Interpersonal Competence Questionnaire (D. Buhrmester, W. Furman, M.T. Wittenberg, & H.T. Reis, 1988). The self and other attachment models and the social skills of negative assertion, self‐disclosure, and conflict management all correlated with depression. Conflict management partially mediated the relationship between attachment self‐model and depression. Implications for counseling are discussed.     

足球运动员股四头肌肌粗值的测定

膝关节受伤以后,最早出现萎缩的肌肉是股四头肌内侧头。足球运动员膝关节伤病多,所以对其股四头肌肌粗值进行定量分析,具有实际意义。以体表形态数据建立数学模型,推导出股四头肌肌粗值,建立了统一的对比衡量标准。肌粗值的变化,首先是受髌骨上５ｃｍ 外缘腿围影响,其次是受髌中围的影响,相关程度分别为高度相关和低度相关,而肌粗值与髌骨上１０ｃｍ 外缘腿围间变化呈不相关。
