To aid the explanation of abstract science concepts, authors of textbooks employ learning tools such as analogies to help students learn. Analogies are believed to allow new material to be more easily assimilated with students' prior knowledge by linking it to their previous experiences. Continuing research on analogies in science textbooks and science teaching is providing a clearer picture of the types of analogies that are available (Duit, 1991), their ranges of presentation style (Curtis & Reigeluth, 1984; Thiele & Treagust, 1992), and their efficacy to effect students' conceptual understandings (Harrison & Treagust, 1993).  相似文献

The systemic changes facing postsecondary institutions today pose a threat to the quality of academic programs unless new faculty can be successfully attracted and retained. To be more competitive in the recruitment and retention of faculty, a better understanding is needed of the adjustment experiences of newly hired faculty. Our study examined the adjustment of new hires at the point of entry into their institutions using research productivity as one indicator of adaptation. It was expected that perceived personal control, age, gender, and type of institution would relate to research productivity. At the beginning of their first and second year, newly hired faculty in three different types of postsecondary institutions responded to a comprehensive questionnaire concerning their initial adjustment experiences. A path analysis indicated both direct and indirect linkages between the independent variables of interest and research productivity. Substantial direct paths were found between the institution type and research productivity, specifically for the research I and liberal arts/comprehensive institutions, and to a lesser degree, between age and research productivity. Age, the research I university, and the liberal arts/comprehensive universities had direct effects on two measures of perceived control and were linked indirectly to research productivity via perceived control. Perceived control resulting from the personal qualities of the faculty members was instrumental to research productivity, whereas perceived control resulting from activities initiated by faculty members were not related to productivity. Surprisingly, gender was not related to research productivity through either direct or indirect paths. If the adjustment of newly hired faculty is viewed in terms of research productivity, then these results suggest that perceived control, the milieu of research-oriented institutions, and age (to a limited extent), are important predictors of faculty performance.  相似文献

ABSTRACT

This study aimed to evaluate responsiveness (ability to detect change) of isometric force-time measures to neuromuscular fatigue in resistance-trained participants using two differing protocols that modified both the instructions provided to participants and the duration of the test. Both protocols were completed at two knee joint angles in the isometric squat test. Ten participants volunteered to take part in this study (age: 27.0 ± 4.5 years, strength training experience: 7.7 ± 2.6 years). Isometric peak force (ISqTpeak) and isometric explosive force (ISqTexp) test protocols were assessed at two joint angles (knee angle 100° and 125°) pre-high intensity strength training, immediately post strength training, 24-h post, 48-h post and analysed for peak and RFD performance. Participants completed eight sets of three repetitions of the back-squat exercise as the high-intensity strength training. Results showed the highest standardised response means (SRM) detected was peak force using the ISqTpeak 100, SRM ?1.97 compared to an SRM of ?1.31 for RFD 200 ms in the ISqTexp 125. Peak force was the most responsive variable using the ISqTpeak protocol, whereas the ISqTexp protocol was most responsive for RFD measures. Therefore, ISqTpeak and ISqTexp test protocols should not be used interchangeably to evaluate RFD variables.  相似文献

Shared governance, a term that is garnering more attention in higher education, is often described as a balancing act between faculty, staff, and administration's participation in planning and decision‐making processes. However, over the last few years, systems of shared governance have evolved to include more and more representation in the decision‐making process.  相似文献
