Six Kansas school psychologists structured their teacher consultation in terms of three consultative modes which varied primarily in the number of follow-up contacts. The findings indicated that follow-up contacts led to greater teacher implementation of recommendations, greater perceived pupil behavior improvement, and greater sense of cooperative planning by the teachers. These outcome differences occurred between follow-up contacts and no follow-up contacts, with outcome differences not occurring between more and less extensive contacts.  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

Sexual harassment is an interdisciplinary topic in organizational research that has received increased attention with the rise of the #MeToo movement. The online environment has complicated the experiences of employees who are sexually harassed by a coworker. One particular medium where online sexual harassment occurs is on social networking sites (SNS), such as Facebook. This research report examined how victims of sexual harassment believe organizations should handle online sexual harassment. We qualitatively coded 153 responses to the question, “What else do you think employers could do to handle sexual harassment on Facebook?” Our findings demonstrated a clear tension between whether harassment on Facebook is a private concern of the employee or a public concern of the employer/organization. Some victims advocating keeping work friends off of Facebook, while others suggesting having open door policies, conversations, and/or trainings. The difference in these approaches illuminates how the victims grappled with the public/private tension, and whether the organization should be made aware of their situations or if victims should handle it themselves. Implications of this research suggest that the blurred boundaries between employee face-to-face and online sexual harassment should continue to be explored, including why victims report harassment and to whom they report it.  相似文献

ABSTRACT

Online learning has become a ubiquitous part of the educational landscape and how teachers are supported in developing approaches to teaching online is a fundamental aspect of the students’ learning experience. Based on the implementation of a professional development course on becoming an online teacher offered in a blended learning mode at one university in Hong Kong, this article proposes that offering this type of professional development in a blended mode is very effective in facilitating enhanced usage of the university’s learning management system. In a blended mode, teachers are actively engaged with blended learning and were found to make more extensive use of features/tools in Blackboard after they attended the professional development course. Results support that offering professional development in a blended mode provides teachers with an authentic student perspective, at the same time as they take guided steps in the teacher’s role in blended learning.  相似文献

To test the hypothesis that formal operational reasoning modes are predictors of critical thinking abilities and grades assigned by teachers in science and mathematics, in September 1986 the Group Assessment of Logical Thinking (GALT) and in December 1986 the Watson-Glaser Critical Thinking Appraisal (WGCTA) were administered to 101 rural students in Grades 9 through 12. The grades assigned by teachers were collected in May 1987. Construct and criterion-related validities and internal-consistency reliability using Cronbach's alpha method were established on the GALT. On the WGCTA, content and construct validities and internal consistency reliability using the split-half procedure, coefficient of stability, and coefficient of equivalence were established. The five formal operational reasoning modes in the GALT were found to be significant predictors of critical thinking abilities and grades assigned by teachers in science and mathematics. The variance in the five critical thinking abilities attributable to the five formal operational reasoning modes ranged between 28% and 70%. The five formal operational reasoning modes explained 29% of the variance in mathematics achievement and 62% of the variance in science achievement.  相似文献

Methods for identifying students with learning disabilities continue to be an area of controversy. The present investigation examined the impact of implementing statewide guidelines for the identification of these students. Data were collected from multidisciplinary team reports on 718 students with learning disabilities who were referred and labeled during the 1983-84 school year (before implementation of statewide learning disability guidelines) and 790 students who were identified during 1987-88 (after implementation of the guidelines). The results of the study revealed that the statewide guidelines significantly changed the characteristics of students who were identified. After the implementation of the guidelines, students with much more severe academic problems were identified. These students were much more likely to have a severe discrepancy and be chronically failing in the regular classroom. However, even with explicit, widely accepted guidelines, approximately one third of all students identified in 1987-88 failed to meet the stated criteria for identification. The implications of these findings for professional practice and future research are discussed.  相似文献

This paper examines the effect of modifiers on the stability of a vinyl acetate/ethylene copolymer dispersion adhesive upon aging. Eighteen common modifiers were added to a well-characterized vinyl acetate/ethylene copolymer dispersion (Dur-O-Set® E-150) in known concentrations and dry-film samples were subjected to 16–17 years of dark aging and seven to eight years of light aging. Yellowing, pH, gloss, swelling, cohesive strength, and flexibility were monitored for changes upon aging. Generally, the neat Dur-O-Set® E-150 (no additives) was found to become acidic on aging, but was fairly resistant to yellowing. It also swelled substantially in toluene, was of high gloss, medium strength, and flexible, and remained so on aging. No modifier was found to improve these properties. Various solvents, wetting agents, and thickeners did not alter the properties by much, while plasticizers, freeze-thaw stabilizer, glycerin, and certain fillers had a more negative effect.  相似文献
