Many social work students feel anxious when taking a statistics course. Their attitudes, beliefs, and behaviors after learning statistics are less known. However, such information could help instructors support students’ ongoing development of statistical knowledge. With a sample of MSW students (N = 101) in one program, this study examined students’ feelings of anxiety and confidence, beliefs about the relevance of statistics to their education and practice, and the relationship of these attitudes and beliefs to their actual statistical competence. The findings indicate that repeated exposure to statistics supports the development of statistical competence, particularly in relevant applied contexts like field education. 相似文献

The purposes of this review were to determine: (1) if different writing activities were more effective than others in improving students’ reading comprehension, and (2) if obtained differences among writing activities was related to how reading comprehension was measured? Meta-analysis was used to examine these questions across studies involving students in grades 1–12. Nineteen studies were located that met inclusion criteria, resulting in 4 writing activities comparisons with 4 or more studies per comparison: summary writing versus answering questions (k = 5), summary writing versus note taking (k = 7), answering questions versus note taking (k = 4), and answering questions versus extended writing activities (k = 6). Effect sizes calculated for each writing activities comparison indicated there were no statistically significant differences for any of these comparisons when effects were averaged over all reading comprehension measures, excluding treatment-inherent measures. However, statistically significant differences were found for two of the comparisons on specific measures. Extended writing enhanced reading comprehension better than question answering on measures where comprehension was assessed via an extended writing activity, whereas summary writing enhanced reading comprehension better than question answering on a free recall measure. The results provide limited support for the theoretical viewpoint that writing activities are differentially effective in improving reading comprehension based on how closely the writing activities are aligned with a particular measure. 相似文献

This study investigated school psychologists’ continuing professional development (CPD) activities, topics, needs, motivations, financial expenditures, and opinions, as well as relationships between select demographic characteristics and certain CPD practices and preferences. A survey was mailed to 1,000 randomly selected Regular Members of the National Association of School Psychologists, resulting in the return of 510 completed surveys, a 51% response rate. Respondents expressed opinions about CPD that were positive, optimistic, and consistent with their high levels of engagement and investments of both time and financial resources. Most respondents reported engaging in 25 or more hours of CPD during the previous year. CPD topics in which they engaged most frequently were response to intervention and academic, behavioral, and social–emotional interventions, and academic screening and progress monitoring. Respondents reported a high level of need for more CPD in those same topic areas, but a low level of need for offerings in standardized assessment. Older school psychologists were less likely to have engaged in CPD relating to contemporary assessment practices and interventions and more likely to have engaged in activities related to standardized assessment. Almost half of the respondents had engaged in CPD through an online activity and reported a desire for more online opportunities. No relationship was found between age and usage of, or positive opinions about, online CPD. 相似文献

Absract Our understanding of the relationship between physical activity and health is constantly evolving. Therefore, the British Association of Sport and Exercise Sciences convened a panel of experts to review the literature and produce guidelines that health professionals might use. In the ABC of Physical Activity for Health, A is for All healthy adults, B is for Beginners, and C is for Conditioned individuals. All healthy adults aged 18–65 years should aim to take part in at least 150 min of moderate-intensity aerobic activity each week, or at least 75 min of vigorous-intensity aerobic activity per week, or equivalent combinations of moderate- and vigorous-intensity activities. Moderate-intensity activities are those in which heart rate and breathing are raised, but it is possible to speak comfortably. Vigorous-intensity activities are those in which heart rate is higher, breathing is heavier, and conversation is harder. Aerobic activities should be undertaken in bouts of at least 10 min and, ideally, should be performed on five or more days a week. All healthy adults should also perform muscle-strengthening activities on two or more days a week. Weight training, circuit classes, yoga, and other muscle-strengthening activities offer additional health benefits and may help older adults to maintain physical independence. Beginners should work steadily towards meeting the physical activity levels recommended for all healthy adults. Even small increases in activity will bring some health benefits in the early stages and it is important to set achievable goals that provide success, build confidence, and increase motivation. For example, a beginner might be asked to walk an extra 10 min every other day for several weeks to slowly reach the recommended levels of activity for all healthy adults. It is also critical that beginners find activities they enjoy and gain support in becoming more active from family and friends. Conditioned individuals who have met the physical activity levels recommended for all healthy adults for at least 6 months may obtain additional health benefits by engaging in 300 min or more of moderate-intensity aerobic activity per week, or 150 min or more of vigorous-intensity aerobic activity each week, or equivalent combinations of moderate- and vigorous-intensity aerobic activities. Adults who find it difficult to maintain a normal weight and adults with increased risk of cardiovascular disease or type 2 diabetes may in particular benefit from going beyond the levels of activity recommended for all healthy adults and gradually progressing towards meeting the recommendations for conditioned individuals. Physical activity is beneficial to health with or without weight loss, but adults who find it difficult to maintain a normal weight should probably be encouraged to reduce energy intake and minimize time spent in sedentary behaviours to prevent further weight gain. Children and young people aged 5–16 years should accumulate at least 60 min of moderate-to-vigorous-intensity aerobic activity per day, including vigorous-intensity aerobic activities that improve bone density and muscle strength. 相似文献

The development of the Nursing Information Consortium of Orange County (NICOC) is traced over time, and reasons for the crises encountered are explored. Based on the experiences of NICOC, recommendations for other consortia are included, as well as for the consortium grant process. 相似文献
