The current study examines the association between parental support and adolescent sleep under varying levels of family stress. Participants included 316 adolescents (M_age = 16.40 years, 43% male) and their parents (M_age = 45.67 years, 91% mothers) from diverse ethnic backgrounds. Both adolescents and parents completed questionnaires and adolescents wore wrist actigraphs and completed self‐reports on their sleep for 7 consecutive days. Results indicated that under contexts of family stress, more parental support was linked to longer sleep duration, less sleep variability, and less time spent awake during the night. Findings suggest that under contexts of family stress, cohesive family relationships may provide a sense of stability and security that is necessary for healthful sleep.  相似文献   

A multivariate analysis of task dimensions related to science concept learning difficulties in primary school children     

Ronald J. Raven 《科学教学研究杂志》1972,9(3):207-212

The purpose of this study was to determine if achievement on a series of problems was affected by differences among task values within a dimension. Values within inference pattern, goal object, and percept dimensions were studied. One hundred and sixty primary school children participated in the study. An analysis of the results of their achievement on the tasks indicate that task solution is affected by the dimension values used in this study. The results of the study suggest that a multidimensional scale of task dimension values should be constructed in order to assist the curriculum specialist in the construction and sequencing of concept tasks for specific grade levels.  相似文献   

Perceptions of the learning environment and associations with cognitive achievement among gifted biology students     

Ronald D. Rita  Catherine S. Martin-Dunlop 《Learning Environments Research》2011,14(1):25-38

This study assessed the perceptions of 146 gifted and 115 non-gifted high school biology students and investigated associations between student perceptions and cognitive achievement. The What Is Happening In this Class? (WIHIC) was used to assess perceptions of actual and preferred learning environments. Data indicated that all students preferred a more favourable environment than the one that they were currently experiencing, but gifted students perceived their actual environment more positively than non-gifted students. Statistically significant associations between the actual learning environment and achievement on a standardised biology test were found for the majority of scales. Teacher Support, Investigation and Equity were all statistically significant independent predictors of student achievement, while Student Cohesiveness had a negative association with achievement. Interviews revealed that students interpreted some WIHIC items differently from how the developers had intended.  相似文献

Relating deaf students' reading and language scores at college entry to their degree completion rates     

Cuculick JA  Kelly RR 《American annals of the deaf》2003,148(4):279-286

Graduation patterns were examined for 905 deaf students (1990-1998) at the National Technical Institute for the Deaf. Students with higher reading and language skills had the best overall graduation percentage. Comparison of recipients of different degrees--bachelor of science (BS) versus fine arts (BFA); associate of applied science (AAS) versus occupational studies (AOS)--showed 92% of BS and 82% of AAS graduates reading at the 9th-grade level or above, versus 65% of BFA and 47% of AOS graduates. Interestingly, 80% of non-degree-earning students read at the 9th-12th grade levels; in absolute terms, they outnumbered graduates with similar reading skills in the AAS and BFA programs combined, and in the BS program. This indicates a need for improved counseling, placement, and retention strategies. Students performed similarly across degree categories, regardless of curriculum requirements and difficulty. Only non-degree-earning students had significantly lower grade averages.  相似文献   

New Media/Internet Research Topics of the Association of Internet Researchers     

Ronald E. Rice 《The Information Society》2005,21(4):285-299

This study summarizes prior reviews of new media and Internet research, and the growth of the term Internet in academic publications and online newsgroups. It then uses semantic network analysis to summarize the interests and concepts of an interdisciplinary group of Internet researchers, as represented by session titles and paper titles and abstracts from the 2003 and 2004 Association of Internet Researchers conferences. In both years, the most frequent words appearing in the paper abstracts included Internet, online, community, social, technology, and research. The 2003 papers emphasized topics such as the social analysis/research of online/Internet communication, community, and information, with particular coverage of access, individuals, groups, digital media, culture; role and process in e-organizations; and world development. The 2004 papers emphasized topics such as access; news and social issues; the role of individuals in communities; user-based studies; usage data; and blogs, women, and search policy, among others.  相似文献   

Focus-on-form instructional methods promote deaf college students' improvement in English grammar     

Berent GP  Kelly RR  Aldersley S  Schmitz KL  Khalsa BK  Panara J  Keenan S 《Journal of deaf studies and deaf education》2007,12(1):8-24

Focus-on-form English teaching methods are designed to facilitate second-language learners' noticing of target language input, where "noticing" is an acquisitional prerequisite for the comprehension, processing, and eventual integration of new grammatical knowledge. While primarily designed for teaching hearing second-language learners, many focus-on-form methods lend themselves to visual presentation. This article reports the results of classroom research on the visually based implementation of focus-on-form methods with deaf college students learning English. Two of 3 groups of deaf students received focus-on-form instruction during a 10-week remedial grammar course; a third control group received grammatical instruction that did not involve focus-on-form methods. The 2 experimental groups exhibited significantly greater improvement in English grammatical knowledge relative to the control group. These results validate the efficacy of visually based focus-on-form English instruction for deaf students of English and set the stage for the continual search for innovative and effective English teaching methodologies.  相似文献   

Effectiveness of Four Track Starting Positions on Acceleration     

Ronald C. Menely  Robert A. Rosemier 《Research quarterly for exercise and sport》2013,84(1):161-165

Abstract

Four sprint starting positions—the bunch, medium, elongated, and hyperextended—were compared on mean elapsed times at distances of 10 and 30 yd. Averages of three starts for each of 30 inexperienced college undergraduate males on each type of start were derived from electronically-controlled measures, the times for both distances being recorded from the same start. Statistical analyses indicated significantly lower elapsed times with the hyperextended starting position.  相似文献   

Establishing workload equivalence: U.S. independent study courses and college residence classes     

Ronald F. Malan  Sandra Feller 《The American journal of distance education》2013,27(2):56-63

Abstract

The Learning Council, a corporate interdivisional enterprise, employs distance learning to meet the learning needs of the organization. Specifically, distance learning is used to increase participation in the Johnson &; Johnson tuition reimbursement program, to offer learning opportunities to employees from a variety of sources, and to bring formal university courses on‐site for employees. The Learning Council is continuing to evaluate these programs as the business environment changes. This article reviews these applications of distance learning and lists considerations for other organizations interested in distance education opportunities. The use of distance learning methods facilitates the maintenance of flexibility and responsiveness in providing continuous learning for employees. The use of a combination of various distance learning methods works well, giving the company a “business edge.”  相似文献
