Given the lack of research on measurement models used to operationalize parental involvement with secondary students, the goal of this research is to examine the measurement properties of the three‐domain conceptualization of parental involvement including school‐based involvement, home‐based involvement, and academic socialization, compared to a more nuanced six domain conceptualization school‐based (1) school/parent communication, (2) attending school activities, home‐based (3) home activities, (4) homework help, academic socialization, (5) parent–child communication about education, and (6) parental aspirations for child's education. When comparing the fit among the models, the six‐factor model had best fit indices and indicated varied correlations among the subdomains. The six‐factor model allowed for more nuanced variations among the subdomains that may be helpful when assessing parental involvement with high school students.  相似文献

The author has presented a rapid overview of the uses of the new information technologies in various aspects of library management and utilization in the United States of America. As early as the 1950's, as concerned librarians had come to realise that manual methods would no longer suffice to cope with the demands being made on libraries, they turned increasingly to automation. Libraries were innovators with regard to the development of large databases and the users of innovations with regard to the development of communications technologies. The latter, the new information and communications technologies (NICT's), are playing increasingly important roles with regard to the operation of libraries in the areas of acquisitions, cataloguing, circulation, reference, administration, inter‐library links including shared cataloguing, resource sharing, and inter‐library loan (now thought of as document delivery). The introduction of these same technologies has required that changes be made in the way librarians are trained, that older practising librarians have their training upgraded, and that library clients be trained in techniques of computer use and information retrieval. For the future, the uses made of the NICT's are bound to expand, leading to increased electronic publishing and distribution and to greater integration of indexes and catalogues. University libraries will increasingly become parts of campus‐wide communications and information networks.  相似文献

Abstract

Advancements in technology have increased preschool children’s access to the Internet. Very little research has been conducted to identify pre-school-aged children’s understandings of the Internet and ramifications of being ‘online’. Without an understanding of children’s thinking about the Internet, it is difficult to provide age- and pedagogically appropriate cyber-safety education. This study developed and pilot-tested an interview schedule that focuses on the Internet thinking and cyber-safety awareness of Australian children aged 4–5 years. The schedule is informed by sociocultural theory, cyber-safety education research and approaches for researching with young children. The schedule shows potential to elicit children’s understandings of the Internet and cyber-safety awareness. Adjustments are required to allow more contextualised responses from children.  相似文献

Clues to how some music can send chills down yourspine are being sought in the moods of chickens. Austrian and U.S.researchers have found that inyoung domestic chicks,the effects of music can be seenin behavioral changes.The experiment reveals:not so muchchicks’musical appreciadon,but hints(暗示,提示)at how the“language of emotions”might have evolved hand-in-handwith emotions.  相似文献

Using an experience sampling methodology, the everyday lives of 153 adolescents with low, middle, or high levels of attention-deficit/hyperactivity disorder (ADHD) characteristics as assessed by either parent or teen were examined. Twice each hour, across two 4-day recording intervals, participants in a longitudinal study of stress and health risks logged their behaviors, moods, and social contexts. Those with high, in contrast to low, ADHD symptom levels recorded more negative and fewer positive moods, lower alertness, more entertaining activities relative to achievement-oriented pursuits, more time with friends and less time with family, and more tobacco and alcohol use. Fewer associations emerged with parent-defined than with teen-defined subgroups, although the differences in alertness, peer and family contexts, entertainment versus achievement activities, and substance use were consistent across sources. Even at subclinical levels, ADHD characteristics were associated with behavioral patterns and contexts that may promote peer deviancy training, unhealthy lifestyle behaviors, and vulnerability to nicotine dependence.  相似文献

Multiple mentor model: A conceptual framework   总被引:1,自引:0,他引:1  
Conclusion This article focused on developing a conceptual framework for the mentoring process. The model is based on the premise that mentoring is not a single event in the life of a worker but rather several events with different levels of mentoring. Each level of mentoring requires a different type of mentor with different types of skills and knowledge, similar to Len Nadler's HRD training model. Therefore, people may need special training to assume the different mentor levels (i.e., Training, Education, and Development Mentors), and workers may need to be trained to recognize that such experiences and people exist to help in their career progression. Counselors can be in the forefront as far as accepting and advocating the use of the Multiple Mentor Model for this training  相似文献

There are numerous research methodologies that may be applied to the study of computer technology, and each has the potential to provide insights into its usefulness. The selection of research methodologies should be driven by the nature of the questions under investigation rather than a predetermined idea that some research methods are superior to others. This article focuses on a particular methodology, case studies, and it describes their potential for making a unique contribution to our understanding of computer technology. The special value of case studies lies in helping us understand the complexities found in classrooms, where the multiple variables that influence computer use interact in complex ways. © 1999 IFIP, published by Kluwer Academic Publishers  相似文献

Chronic school refusal has traditionally been classified under broad categories such as school phobia and truancy. However, the need for improved recognition and treatment of school refusal has heightened efforts to identify subtypes of school refusal behavior. Recent efforts have focused on functional subtypes of school refusal. This article purposes to extend recent efforts by showing that the three basic subtypes of anxiety, avoidance, and malingering are not only functional, but consistent with refusal characteristics, empirical evidence from factor analysis and clinical diagnosis over the past decade, and treatment approaches. Such extension is intended to aid practitioners in further understanding and using functional subtypes. © 2000 John Wiley & Sons, Inc.  相似文献
