Conclusion The preceding overview of counseling and information services for adults in the English-speaking Caribbean indicates that there is a considerable amount of activity which varies, of course, from country to country. What is also evident is that such services are rarely offered in a very formal way, that often they are voluntary, that there is at present very little coordination of activity, and that, except in very few cases, those providing such services have not been specifically trained for this task. The thrust for the future must be toward securing personnel trained to provide service of this kind and toward developing better coordination among the agencies and individuals involved, while at the same time seeking to expand such services and increase the number of persons with whom direct contact is made. 相似文献

The Science Co-op is a local systemic change project that connects eight regional clusters of elementary schools in rural Missouri and Iowa in the USA. These clusters are comprised of 38 school districts distributed over 40,000 square miles and include more than 1,400 teachers and 20,000 elementary school students. The project stresses inquiry science in the classroom and involves investigating science ideas using a constructivist approach and cross-curricular connections. Within the frameworks of the Science Co-op project a technology known as Interactive Television (ITV) allows for almost real-time interaction (a 3–5 second delay) within the state boundaries of Missouri and Iowa, respectively. The primary goals of the ITV sessions are to enhance the science content and science pedagogical knowledge among the population of elementary school teachers that they may have lacked in their prior education, and to reinforce and extend instructional strategies emphasized in this local systemic change project. In this study the participants' self-reported learning and reactions to live ITV sessions and videotaped, delayed broadcast of ITV sessions were compared. Regression analysis results show teaching experience's influence on overall satisfaction with ITV (p<0.05) while mode attended, perceived technical difficulty, preferred mode, and perceived new skills or content learned in the session entered the regression equation at p=.000. Further t-tests suggested p>0.05 for perceived new skills and content learned on the different modes of communication. 相似文献

Several authors have suggested reasons for children transferring to new schools, and they have hypothesized that the reasons may affect the nature and tenure of the transition process. The present study investigated the reasons parents of 451 elementary school children gave for changing schools and demonstrated that the reasons influenced children's ability to adjust to their new schools. Specifically, children transferring because their old school closed were more competent academically and had a higher average socioeconomic status than did the other groups. On the other hand, those transferring because of changing households had poorer academic performance and more stressful life events on average than the other groups. Finally, reasons for moving not only vary according to race, but the effects of the reasons are different for each racial group. Implications for school personnel seeking to integrate transfer students into their schools effectively are discussed. 相似文献

There have been many conflicting observations between the linear or curvilinear decline in maximal heart rate (HRmax) with age. The aim of this study was to determine if linear or curvilinear equations would better describe the decline in HRmax with age in individuals of differing cardiorespiratory fitness (CRF) levels. Treadmill cardiopulmonary exercise test (CPX) results from participants (1510 men and 1134 women; 18–76 years) free of overt cardiovascular disease were retrospectively examined using cross-sectional and longitudinal study designs. Participants completing ≥2 CPX with ≥1 year between test dates were included in the longitudinal analysis (325 men and 150 women). Linear and quadratic regressions were applied to age and HRmax for the whole cohort and respective CRF groups (high, moderate, and low, relative to age and gender normative values). To test for differences among linear, quadratic, and polynomial equations, the change in R2 (cross-sectional analysis) and Bayesian information criterion (BIC) (longitudinal analysis) from the linear to the more complex models were calculated. The quadratic or polynomial regression in the cross-sectional analysis, marginally improved the variance in HRmax explained by age compared to the linear regression for the whole cohort (0.2%), moderate fit group (0.3%), and low fit group (0.8%). With no improvements in the high fit group. BIC did not improve for any CRF category in the longitudinal analysis. In conclusion, the minimal differences among linear, quadratic, and polynomial equations in the respective CRF groups, emphasizes the use of linear prediction equations to estimate HRmax. 相似文献

Students’ engagement with two-dimensional (2D) representations as opposed to three-dimensional (3D) representations of anatomy such as in dissection, is significant in terms of the depth of their comprehension. This qualitative study aimed to understand how students learned anatomy using observational and drawing activities that included touch, called haptics. Five volunteer second year medical students at the University of Cape Town participated in a six-day educational intervention in which a novel “haptico-visual observation and drawing” (HVOD) method was employed. Data were collected through individual interviews as well as a focus group discussion. The HVOD method was successfully applied by all the participants, who reported an improvement of their cognitive understanding and memorization of the 3D form of the anatomical part. All the five participants described the development of a “mental picture” of the object as being central to “deep learning.” The use of the haptic senses coupled with the simultaneous act of drawing enrolled sources of information that were reported by the participants to have enabled better memorization. We postulate that the more sources of information about an object, the greater degree of complexity could be appreciated, and therefore the more clearly it could be captured and memorized. The inclusion of haptics has implications for cadaveric dissection versus non-cadaveric forms of learning. This study was limited by its sample size as well as the bias and position of the researchers, but the sample of five produced a sufficient amount of data to generate a conceptual model and hypothesis. 相似文献

The link between physical activity and weight loss has precipitated interest in interventions to foster adherence to exercise. It has been suggested that treatment effects, when significant, should be analyzed to determine theory-based mediators. This research assessed possible mediation of changes in Physical Self-Concept, Exercise Self-Efficacy, Total Mood Disturbance, and Body Areas Satisfaction scores on the relationship between exercise session attendance and participation by obese women in a 6-month treatment based on tenets of social cognitive theory (n = 73) or a control condition (n = 64). Participation in the treatment was associated with significantly greater exercise session attendance and significantly greater improvements in Physical Self-Concept, Exercise Barriers Self-Efficacy, and Body Areas Satisfaction. Overall, changes in the assessed psychological factors demonstrated significant mediation of the association between group membership and exercise session attendance, R2 = .23, with only change in Physical Self-Concept scores providing a significant unique contribution. Extensions of this research across different sample types, and with longer durations, were suggested to refine theory and, ultimately, improve exercise adherence treatments. 相似文献

The first year of a 5 year professional development project for elementary teachers in two mid-western states integrated a bridge of two distinctly different distance education networks (T-1 and fiber optics) to provide science professional development for elementary school teachers in rural communities. Interactive television (ITV), the title given to the distance component, consisted of a series of twenty-four, 2 h presentations by scientists and content specialists. It provided expansion to the science pedagogical content knowledge of the elementary teachers involved. Eighty-five teachers in 38 school districts from the two states completed individual surveys following the final ITV session. Analysis of variance of participants post-session survey scores yielded differences (p < 0.05) on the subscales measuring perceived effectiveness of using distance education for professional development purposes and years of teaching experience. Teachers with over 20 years of classroom experience perceived the use of distance education technologies for science professional development to be more effective than teachers with 16–20 years of classroom experience. These results might suggest another digital divide. 相似文献

Socially reared juvenile bonnet macaques responded at high sustained levels in an operant task for presentation of color videotaped television images of social stimuli. Absolute levels of response depended upon the nature of the stimulus. In two experiments, subjects responded at 60.8% and 74.6% of the 1-h experimental sessions for presentation of a color videotape of a conspecific adult female moving freely in an enclosed stimulus chamber. In a later experiment, subjects maintained high levels of response during 15-min sessions for presentations of the conspecific image, but responded with significantly shorter duration responses for similar presentation of a videotape of an adult female of another macaque species, a still picture of a conspecific adult female, and a videotape of the empty stimulus chamber. With longer, 1-h, stimulus presentation, the three social stimuli sustained high levels of response while responses for presentation of the empty stimulus chamber waned significantly over the experimental session. The sustained high levels of response obtained over several hours of stimulus presentation suggest the value of color videotape stimuli in the experimental study of social perception in nonhuman primates. 相似文献
