At the University of Maine, middle and high school teachers observed more than 250 university science, technology, engineering, and mathematics classes and collected information on the nature of instruction, including how clickers were being used. Comparisons of classes taught with (n = 80) and without (n = 184) clickers show that, while instructional behaviors differ, the use of clickers alone does not significantly impact the time instructors spend lecturing. One possible explanation stems from the observation of three distinct modes of clicker use: peer discussion, in which students had the opportunity to talk with one another during clicker questions; individual thinking, in which no peer discussion was observed; and alternative collaboration, in which students had time for discussion, but it was not paired with clicker questions. Investigation of these modes revealed differences in the range of behaviors, the amount of time instructors lecture, and how challenging the clicker questions were to answer. Because instructors can vary their instructional style from one clicker question to the next, we also explored differences in how individual instructors incorporated peer discussion during clicker questions. These findings provide new insights into the range of clicker implementation at a campus-wide level and how such findings can be used to inform targeted professional development for faculty.  相似文献

This study sought to assess current and future school psychologists’ attitudes toward and preparedness to address the needs of lesbian, gay, bisexual, and transgender (LGBT) students in schools. Two‐hundred seventy‐nine school psychologists (n = 162, 58%) and school psychology graduate students (n = 117, 42%) were included in the study. Participants completed measures of attitudes toward LGBT students, preparedness to address the needs of LGBT youth, and social desirability. For both school psychologists and graduate students, increased education was associated with improved attitudes and increased preparedness to treat LGBT youth. For school psychologists, presence of a gay‐straight alliance was associated with increased knowledge about LGBT youth, as well as higher ratings of preparedness to treat LGBT youth; the same associations did not hold true for the graduate students. These findings have implications for the training and practice of school psychologists in addressing the needs of LGBT youth in schools.  相似文献

Emerging fathers experience a variety of stressors, including identity and role transitions, changes in their relationships, and challenges in developing caregiving skills. Increasing expectations for father involvement in childcare are emphasizing the importance of the father role, but social supports for new fathers remain scarce. Nineteen expectant and new fathers participated in a pilot 5-week group intervention aimed at improving stress coping and involvement attitudes using a combination of mindfulness practices and skill-building for parenting and partner communication. We administered surveys pre- and postintervention to assess efficacy in the areas of stress, depressive symptoms, father involvement attitudes, and mindfulness. Within-participant differences were compared across participants as well as examining individual reliable change. Results indicated initial reductions in stress and depressive symptoms and increases in the mindfulness constructs of nonjudgment and nonreactivity. No significant changes were found in father involvement attitudes. Perinatal intervention specific to fathers holds promise as an underexplored avenue for supporting families across the transition to parenthood.  相似文献

ABSTRACT

The objective of this study was to analyse the effect of the use of social networks in smartphones or playing video games on the passing decision-making performance in professional soccer athletes. Participants were 25 male professional soccer athletes (mean ± SD: age 23.4 ± 2.8 years). The participants performed three randomised conditions divided into three groups: control (CON), smartphone (SMA), and video game (VID). Before and after each experimental condition, the Stroop Task assessed the level of induced mental fatigue. Then, the athletes performed a simulated soccer match. A CANON® camera recorded the matches for further analysis on passing decision-making performance. A group effect was identified (< .01) with impairment on passing decision-making performance for the SMA (p = .01, ES = 0.5) and VID (p = .01, ES = 0.5) conditions. We concluded that the use of social networks on smartphones and/or playing video games right before official soccer matches might impair the passing decision-making performance in professional soccer athletes.  相似文献

Self‐efficacy pertains to individuals’ belief about their capability to accomplish a task; consequently, school counselors’ positive self‐efficacy is a theoretically based prerequisite for their facilitation of school‐based interventions. In addition, school counselor‐led interventions and comprehensive, developmenta l guidance programs benefit students’ personal social, academic, and career development. Therefore, this investigation examined the contribution of practicing school counselors’ (N = 693) self‐efficacy in relation to the frequency of their programmatic service delivery. The findings indicate that participants’ self‐efficacy scores contributed to the frequency of their programmatic service delivery (48% of the variance explained). Implications for school counselors, supervisors, and educational researchers are discussed.  相似文献

Abstract

This article reports the results of a quantitative and systematic analysis comparing usage rates between English-language and French-language e-monograph titles at Laurentian University, Canada. Full-text viewings were collected as usage metrics. English-language e-monographs exhibited medium strength linear relationships between collection size and usage. On the other hand, French-language e-monographs exhibited weak linear relationships between collection size and usage. The French-language e-monograph collection experienced a higher rate of full-text use, relative to size. The cost-per-viewing ratio for the English-language e-monograph collection was higher than those that calculated for the French-language collection.  相似文献

Objective: To analyze the possible dose-response association between components of sports participation (intensity, volume and previous engagement) and 4-year mortality rates among Brazilian adults.

Methods: 679 males and females (mean age among men = 66.7 ± 9.3 years old and mean age among women = 64.8 ± 8.9 years old) composed the study sample. Sports participation was assessed using Baecke’s questionnaire, which considers intensity, duration and previous engagement. Medical records were used to identify the cause of the death. Cox regression analysis was performed to determine the independent associations of exercise components and mortality.

Results: Participants that reported exercising at moderate-vigorous intensity (Moderate/vigorous: 4.1% versus None/light: 10.3% [p-value = 0.012]; HR = 0.42 [0.1 to 0.94)] and for more than four months (≥4 months: 5.3% versus <4 months: 10.2% [p-value = 0.038]; HR = 0.47 [0.24 to 0.94]) had lower mortality risk. The percentage of survival according to all-cause mortality was significantly higher for participants engaged in sports at moderate-vigorous intensity (p-value = 0.014), as well as for those engaged in sports for periods superior than four months (p-value = 0.036).

Conclusion: We found higher percentage of survival among adults engaged in sports at moderate-vigorous intensity and with at least four months of previous engagement.  相似文献
