The Educational and Career Interest scale, a self-report instrument measuring high school students’ educational and career interest in STEM, was developed and validated in two studies conducted during 2010 and 2011. Study 1 included data from 92 high school students, in which exploratory factor analysis (EFA) was conducted with an initial item pool of 20 items. EFA identified three factors: educational and career interest in science, educational and career interest in technology, and educational and career interest in mathematics. Study 2 utilized data from 658 students to revisit the three-factor model using confirmative factor analysis. The two studies provide strong evidence that the scale is both valid and reliable. 相似文献

A survey of perceptions of Second Life as a training and development tool indicates that its use is still in the early stages of the adoption curve. Moreover, professionals who are familiar with it do not typically express the same enthusiasm for it as media reports seem to indicate. 相似文献

In social science research on academic careers and mobility, a persistent finding is the substantial effect of doctoral origin on the prestige of the first institution at which one works. There also seems to be a substantial tendency among academic institutions to follow institutional self-recruitment. That is, an academic is more likely to be recruited by an institution in the same prestige category as that which produced him or her. From the period of large expansion to the slowdown of growth in higher education, how have patterns of institutional self-recruitment changed? While elite institutions tend to recruit Ph.D.s from a similar group of institutions, as we go down the line of institutional prestige hierarchy there is a diminishing trend of self-recruitment among similar institutions. This study suggests that there is a general downward mobility in prestige for newly recruited Ph.D.s in a period of a tighter market. While Ph.D.s from elite research universities have continued to increase their chances for being employed at lesser institutions, Ph.D.s from less prestigious graduate institutions have trickled down in the prestige hierarchy. The data used for our analysis are from the National Research Council's Doctorate Records File covering the period from 1969 to 1981, which is marked by significant changes in higher education. The techniques applied are developed by Leo Goodman's loglinear models. 相似文献

ABSTRACT Various factors influence e‐learners' feelings of satisfaction and dissatisfaction with their e‐learning experience, but from an extensive search with six major academic research databases we did not find any research that demonstrated comprehensive profiles of satisfying and dissatisfying factors in e‐learning. We conducted a qualitative study to initiate the effort. We used Thorndike's law of effect and Herzberg's motivation‐hygiene theory as the conceptual frameworks for our study. Thorndike's law of effect applied to human psychology suggests that people would try to avoid annoying stimuli whereas they would try to preserve satisfying stimuli. Herzberg's motivation‐hygiene theory suggests that different factors influence extreme satisfaction and extreme dissatisfaction on the job. Using the two theories as the conceptual frameworks, we revealed profiles of satisfaction‐dissatisfaction factors in e‐learning by analyzing extant data of course evaluation obtained from 17 e‐learning courses. In this article, we provide recommendations on how other e‐learning institutions might utilize the research findings to optimize their e‐learning programs and we discuss the potential impact of such interventions on overall institutional outcomes such as learner retention. 相似文献

Abstract Prior to 1997, the Department of Instructional & Performance Technology (IPT) online program at Boise State University faced a high student dropout rate. The IPT turned to Keller's ARCS model, Kaufman's Organizational Elements Model, and Kirkpatrick's evaluation model throughout the processes of improving the motivational appeal of the online course for the first‐time adult learners and solving the attrition problem. In this article, the author describes a long‐term evaluation case study and explains how she systematically designed and implemented various instructional interventions to reduce attrition. She also presents the results of systemic evaluations. 相似文献

ABSTRACTThe Powerful Tools for Caregivers (PTC) program is designed to help caregivers develop skills to improve their self-efficacy in caregiving. To demonstrate the effectiveness of the PTC program in Boise, Idaho, the program’s pre-survey (n = 277), end-of-program survey (n = 131), and 6-month follow-up post-survey data (n = 100) collected between 2011 and 2017 were analyzed in this study. The end-of-program survey data indicated that caregivers viewed the quality of the program to be excellent and that all of them felt more confident as a caregiver. Factor analysis and reliability testing on the pre-survey data confirmed that seven questions included in the pre- and 6-month follow-up post-survey instruments reliably measured a single factor named as caregiver confidence. A paired samples t-test on 76 complete sets of pre- and 6-month follow-up post-survey data on the seven questions revealed that caregivers improved their confidence in caregiving to a statistically significant level (p < .001, d = 45). Additional paired samples t-tests on each of the seven questions with the Bonferroni correction showed statistically significant improvements in three areas: making tough decisions (p < .001, d = .53), coping with emotions (p < .001, d = .54), and using stress-reducing activities (p < .007, d = .33). Caregivers experienced the greatest improvement in their confidence in making tough decisions. Despite these significant improvements, caregivers still struggled with finding ways to reduce stress and manage their emotions associated with caregiving as shown by the lowest pre- and 6-month follow-up post-survey scores. In addition to the study results, several considerations when synthesizing PTC research results are discussed. 相似文献

The purpose of this study is to review the main perspectives or issues dealt with in the research on considered to be key
competences, in order to develop a fuller understanding of how human competence functions. As a result of this review, two
themes considered as having important implications for the actual practices can be identified: that there exists an holistic
nature with different aspects of a given competence and that influences of a contextual and cultural nature are factors which
affect the operation of human competence. By incorporating four characteristics and three domains of competence with the review
conducted in this study, we began to appreciate what the research on human characteristics related to key competences has
achieved and what is needed for future research. 相似文献

In its late stage, Alzheimer's disease results in progressive muscle weakness in the arms and legs. The aim of this study was to determine whether mice expressing the skeletal muscle-specific mutant PS2 gene (a model of Alzheimer's disease) are a useful experimental system to study the protective effect of exercise on A beta-42 reduction, improvement of behavioural function and changes in metabolic parameters. With this aim in mind, the transgenic mice were subjected to treadmill exercise for 3 months. The results showed that in transgenic mice, but not in normal mice, treadmill exercise resulted in a reduction of A beta-42 deposits and an improvement in behavioural function, thereby restoring normal concentrations of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglyceride. Thus, exercise may represent a practical therapeutic strategy for use with human patients with Alzheimer's disease. 相似文献
