This paper provides an overview of the Inquiry-Oriented Differential Equations (IO-DE) project and reports on the main results
of a study that compared students’ beliefs, skills, and understandings in IO-DE classes to more conventional approaches. The
IO-DE project capitalizes on advances within mathematics and mathematics education, including the instructional design theory
of Realistic Mathematics Education and the social negotiation of meaning. The main results of the comparison study found no
significant difference between project students and comparison students on an assessment of routine skills and a significant
difference in favor of project students on an assessment of conceptual understanding. Given these encouraging results, the
theoretical underpinnings of the innovative approach may be useful more broadly for undergraduate mathematics education reform. 相似文献

The authors explored the pattern of change in counseling students’ (N = 373) counseling self‐efficacy (CSE) throughout their program and the influence of identifying variables. Results indicated that specific factors significantly predicted students’ initial CSE levels and the rate of CSE change. Implications for future research and counselor education programs are presented. 相似文献

This study investigated differences between two approaches to chained equipercentile (CE) equating (one‐ and bi‐direction CE equating) in nearly equal groups and relatively unequal groups. In one‐direction CE equating, the new form is linked to the anchor in one sample of examinees and the anchor is linked to the reference form in the other sample. In bi‐direction CE equating, the anchor is linked to the new form in one sample of examinees and to the reference form in the other sample. The two approaches were evaluated in comparison to a criterion equating function (i.e., equivalent groups equating) using indexes such as root expected squared difference, bias, standard error of equating, root mean squared error, and number of gaps and bumps. The overall results across the equating situations suggested that the two CE equating approaches produced very similar results, whereas the bi‐direction results were slightly less erratic, smoother (i.e., fewer gaps and bumps), usually closer to the criterion function, and also less variable. 相似文献

The purpose of the current study is to identify the user criteria and data-driven features, both textual and non-textual, for assessing the quality of answers posted on social questioning and answering sites (social Q&A) across four different knowledge domains—Science, Technology, Art and Recreation. A comprehensive review of literature on quality assessment of information produced in social contexts was carried out to develop the theoretical framework for the current study. A total of 23 user criteria and 24 data features were proposed and tested with high-quality answers obtained from four social Q&A sites in Stack Exchange. Findings indicate that content-related criteria and user and review features were the most frequently used in quality assessments, while the importance of user criteria and data features was variable across the knowledge domains. In the Technology Q&A site containing mostly self-help questions, the utility class was the most frequently used group of criteria. The popularity of the socio-emotional class was more apparent in discussion-oriented topic categories such as Art and Recreation, where people seek others’ opinions or advice. Users of Art and Recreation Q&A sites in Stack Exchange appear to place more value on answerers’ efforts and time, good attitudes or manners, personal experience, and the same taste. The importance of user features and the emphasis on answerer's expertise on the Science Q&A site was observed. Examining the connection or gap between user quality criteria and data features across the knowledge domains could help to better understand users’ evaluation behaviors for their preferred answers, and identify the potential of social Q&A for user education/intervention in answer quality evaluation. This examination also offers practical guidance for designing more effective social Q&A platforms, considering how to customize community support systems, motivate contributions, and control content quality. 相似文献

This study examines caregiver burden and social supports perceived by mothers raising children with developmental disabilities in South Korea. Mothers residing in the metropolitan areas of Seoul (n = 181) responded to the mail survey with a 56.6% response rate. Respondents expressed a high level of overall burden, particularly in financial domains. Greater subjective caregiver burden for these mothers was associated with: increased disability‐related costs; maternal factors such as being younger and having higher educational attainment; and less social support. Extra cost related to disabilities was the strongest predictor of increased caregiver burden. Findings indicate that social support can reduce this burden. Implications for the practices of social service agencies and policy are discussed. 相似文献

Korean preschoolers' advanced inhibitory control and its relation to other executive skills and mental state understanding 总被引：3，自引：1，他引：3
This study assessed executive function and mental state understanding in Korean preschoolers. In Experiment 1, forty 3.5- and 4-year-old Koreans showed ceiling performance on inhibition and switching measures, although their performance on working memory and false belief was comparable to that of Western children. Experiment 2 revealed a similar advantage in a sample of seventy-six 3- and 4-year-old Koreans compared with sixty-four age-matched British children. Korean children younger than 3.5 years of age showed ceiling effects on some inhibition measures despite more stringent protocols and the link between executive function and mental state understanding was not as strong as in the British sample. The results raise key questions about the nature and development of the executive system and its relation to social understanding. 相似文献
