This study explored Ridley and Novak's (1983) hypothesis that gender differences in science achievement are due to differences in rote and meaningful learning modes. To test this hypothesis, we examined gender differences in fifth- and sixth-grade students' (N = 213) self-reports of confidence, motivation goals (task mastery, ego, and work avoidance), and learning strategies (active and superficial) in whole-class and small-group science lessons. Overall, the results revealed few gender differences. Compared with girls, boys reported greater confidence in their science abilities. Average-achieving girls reported greater use of meaningful learning strategies than did their male counterparts, whereas low-ability boys reported a stronger mastery orientation than did low-ability girls. The results further showed that students report greater confidence and mastery motivation in small-group than whole-class lessons. In contrast, students reported greater work avoidance in whole-class than small-group lessons. In general, the findings provide little support for Ridley and Novak's hypothesis that girls tend to engage in rote-level learning in science classes. Differences in self-reports of motivation and strategy-use patterns were more strongly related to the student's ability level and to the structure of learning activities (small group vs. whole class) than to gender. © 1996 John Wiley & Sons, Inc.  相似文献

Objectives:Analyze the information-seeking practices and identify the information and education needs of nurses in a war veterans nursing home. Develop an online toolkit for use at the nurses'' stations to meet nurses'' health information needs.Methods:Investigators employed mixed methods to determine the health information needs of the participating nurses at the skilled nursing facility using an online questionnaire and in-person observations. Resulting data was compared to determine how nurses'' self-reported data corresponded with investigator observations.Results:Twenty-seven out of a total of thirty-five nurses responded to the online questionnaire. The study principal investigator also observed a total of twelve nurses working across all shifts. The online questionnaire asked nurses to identify when they need health information for an acute clinical scenario. Nurses self-reported feeling most confident in assessing falls and pain, followed by medication adherence and skin integrity. Issues most frequently encountered during observation of nurses were falls, interventions surrounding cognitive ability or dementia, and use of antibiotics. Nurses reported and were observed to consult colleagues most frequently, followed by drug handbooks and relying on nursing experience.Conclusion:Nurses in skilled nursing facilities will benefit from ready online access to current drug handbooks as well as information resources surrounding commonly encountered clinical issues and stated needs. An outcome of this project is an online toolkit site using a LibGuide created specifically for this purpose. Researchers purchased laptop computers that were installed at each of the nurses'' stations to provide ready access to the toolkit site.  相似文献

This study assessed changes in selected physiological and kinematic variables over 6 weeks of treadmill skating in an effort to understand the process of habituation to this novel training modality. Seven male, Atom-A hockey players who were injury-free and had no previous treadmill skating experience participated in the study. Players performed four 1-min skating bouts at progressively increasing speeds, each week, for 6 weeks. One speed (10.5 km/h) was repeated weekly to allow for assessment of the habituation process. Our criteria for habituation were: a decrease in stride rate, heart rate and rating of perceived exertion, and an increase in stride length, trunk angle and vertical movement of the centre of mass, leading to a plateau, over the course of the 6-week study. Significant decreases were seen in stride rate, heart rate and ratings of perceived exertion, and significant increases were found in stride length. Some of these changes were evident after only one week of training and all were present by week 4. After 6 weeks (24 min) of exposure to treadmill skating, all participants displayed a visibly more efficient skating style.  相似文献
