Ego depletion negatively affects knowledge retrieval in secondary school students     

Chris Englert  Alex Bertrams 《教育心理学》2017,37(9):1057-1066

In the present study, we tested the assumption that performance in a knowledge retrieval test would be lower in secondary school students with temporarily depleted self-control strength (n = 53) compared to secondary school students with temporarily available self-control strength (n = 56). After manipulating self-control strength, students were instructed to memorise the names and the functions of the human eye and to recall as many names and functions as possible following a one-min distraction task. The results supported our assumptions, as students with depleted self-control strength performed significantly worse in the knowledge retrieval task compared to students whose self-control strength had not been temporarily depleted. The results suggest that depleted self-control strength may negatively affect academic performance and hinder a successful academic career. The theoretical and practical implications of these findings are discussed.  相似文献   

Assessing the Psychometric Properties of the Attitudes Toward Seeking Professional Psychological Help Scale-Short Form in Mainland China     

Ke Fang  Alex L Pieterse  Myrna Friedlander  Junhong Cao 《International journal for the advancement of counseling》2011,33(4):309-321

This investigation tested the psychometric properties of the Attitudes Toward Seeking Professional Psychological Help Scale-Short Form (ATSPPH-SF; Fisher and Farina [Journal of College Student Development, 36, 368–373, 1995]) in a sample of 338 Mainland Chinese college students. Using back-translation, the ATSPPH-SF was translated into simplified Chinese. Confirmatory factor analysis did not support the original one-factor model. Subsequently, exploratory factor analysis suggested a 7-item, two-factor model; however, the new factor structure yielded poor reliability coefficients, below .60. Results suggest that the help-seeking construct as operationalized by the ATSPPH-SF may not be valid for the Chinese population. The importance of designing indigenous instruments for help-seeking attitudes is discussed.  相似文献   

Effects of childhood setting and interaction with nature on academic performance in introductory college-level courses in the environmental sciences     

Melanie A. Spero  Nick J. Balster  Alex W. Bajcz 《Environmental Education Research》2019,25(3):422-442

This study explored the relationships between student background and academic performance in college introductory environmental science (ES) courses at a large U.S. research university with the premise that this analysis may inform teaching practices, curricula, and efforts to increase retention. We surveyed over 700 students across eleven introductory ES courses and used multiple linear mixed-effects regressions to model the data. We found that students who grew up in rural settings or who had frequent childhood interactions with natural environments earned higher grades, on average, than students from urban settings or with fewer childhood interactions with natural environments. Our results indicate that students reporting frequent childhood interactions with forests, for example, were projected to earn grades up to 1.5 letter grades higher in these courses than students with no such interactions. In addition, students with frequent childhood interactions with nature were likelier to report that such interactions helped them in their ES course, suggesting that these students may recognize the value of these experiences. Greater interest in the subject matter also correlated with higher ES course grades, whereas amount of prior ES coursework did not. We discuss the possible implications of these correlations for ES academic performance and educational practice.  相似文献   

Empowering student learning through Tablet PCs: A case study     

Sandy C. Li  Jacky W. C. Pow  Emily M. L. Wong  Alex C. W. Fung 《Education and Information Technologies》2010,15(3):171-180

Empowering students to learn through ICT is seen as a way to address the growing awareness and demand for preparing students to effectively participate in the emerging global knowledge economy. It is believed that, in order to maintain competitiveness in a global economy, traditional classroom practices must be re-conceptualized in a way that enables students to engage themselves in knowledge building, to become more self-directed, and to assume greater autonomy and social responsibility over their own learning. In this article, we report a case study on the use of Tablet PCs to support teaching and learning in a primary school in Hong Kong, and provide insights into how schools can harness and capitalize on the opportunities offered by such emerging technologies.  相似文献   

Evaluation of Quality of DNA Extracted from Buccal Swabs for Microarray Based Genotyping     

Alex Livy  Sayhean Lye  Chahil K. Jagdish  Nurul Hanis  Velapasamy Sharmila  Lian Wee Ler  Bagali Pramod 《Indian journal of clinical biochemistry : IJCB》2012,27(1):28-33

Buccal cell usage has been shown by many to be a cost effective and safe method to isolate DNA for various biological experiments especially large epidemiological studies (Garcia-Closas et al. Cancer Epidemiol Biomarkers Prev 10:687–696, 2001). Non-invasive DNA collection methods are preferred over phlebotomy in order to increase study participation and compliance in research centers and for sick patients in hospital settings. There have been conflicting reports about the methodology and results obtained from using buccal DNA. It is not very clear if phlebotomy can be confidently replaced by buccal cell DNA. It is often left for the user to take an intelligent decision. To address this issue, we compared the performance of buccal and blood DNA from same subjects in a genotyping experiment and this paper reports the results. Cotton swab derived buccal cells were scraped from the inner side of cheeks from 16 subjects, and blood was also drawn from the same 16 subjects participating in a genotypic association study of a lipid disease. The DNA quality was assessed by resolving on agarose gels, checking purity (A260/A280) and finally by microarray hybridization. This study showed that DNA degradation affects the total yield and performance of the buccal DNA when compared to the blood DNA in microarray based genotyping. Genotyping results can be seriously compromised if care is not taken to check the quality and yields of such specimens.  相似文献   

Classroom teachers and physical activity integration     

Donetta J. Cothran  Pamela Hodges Kulinna  Alex C. Garn 《Teaching and Teacher Education》2010

This project examined 23 teachers’ involvement in a curricular project to integrate physical activity into the school day. The teachers represented all grade levels and worked in schools that served Native American students in the United States. Interviews occurred twice during the year-long project. Data were analyzed via constant comparison. Teachers’ willingness to engage was influenced positively by caring about students and their own personal wellness history. Their engagement was impeded by institutional factors of scheduling and assessment pressures. The results provide insights into how teachers might be persuaded to and prepared for the implementation of similar programs in new locations.  相似文献

Instructional Tools in Educational Measurement and Statistics (ITEMS) for School Personnel: Evaluation of Three Web-Based Training Modules     

Rebecca Zwick  Jeffrey C. Sklar  Graham Wakefield  Cris Hamilton  Alex Norman  Douglas Folsom 《Educational Measurement》2008,27(2):14-27

In the current No Child Left Behind era, K‐12 teachers and principals are expected to have a sophisticated understanding of standardized test results, use them to improve instruction, and communicate them to others. The goal of our project, funded by the National Science Foundation, was to develop and evaluate three Web‐based instructional modules in educational measurement and statistics to help school personnel acquire the “assessment literacy” required for these roles. Our first module, “What's the Score?” was administered in 2005 to 113 educators who also completed an assessment literacy quiz. Viewing the module had a small but statistically significant positive effect on quiz scores. Our second module, “What Test Scores Do and Don't Tell Us,” administered in 2006 to 104 educators, was even more effective, primarily among teacher education students. In evaluating our third module, “What's the Difference?” we were able to recruit only 33 participants. Although those who saw the module before taking the quiz outperformed those who did not, results were not statistically significant. Now that the research phase is complete, all ITEMS instructional materials are freely available on our Website.  相似文献
