“Deep learning” represents student engagement in approaches to learning that emphasize integration, synthesis, and reflection. Because learning is a shared responsibility between students and faculty, it is important to determine whether faculty members emphasize deep approaches to learning and to assess how much students employ these approaches. This study examines the effect of discipline on student use of and faculty members’ emphasis on deep approaches to learning as well as on the relationships between deep approaches to learning and selected educational outcomes. Using data from over 80,000 seniors and 10,000 faculty members we found that deep approaches to learning were more prevalent in Biglan’s soft, pure, and life fields compared to their counterparts. The differences were largest between soft and hard fields. We also found that seniors who engage more frequently in deep learning behaviors report greater educational gains, higher grades, and greater satisfaction with college, and that the strength of these relationships is relatively consistent across disciplinary categories.  相似文献

The explosive growth of Internet and E‐mail use has provided exceptional opportunities for humans to mediate their communication and thus their relationships in new ways. This study reports on a content analysis of interrogative strategies used in E‐mail messages exchanged over six months between intergenerational sets of senior citizens and youngsters. A great deal of relationship development is facilitated by the use of questions which are a core aspect of uncertainty reduction processes. While Uncertainty Reduction Theory (URT) has been a predominant theoretical position for examining face‐to‐face initial interaction, its utility for examining communication in an asynchronous, computer‐mediated environment was only partially effective. Data analyses focused on politeness of questions, types of questions, and, temporal effects. Results suggest that the interrogative strategies we engage in to achieve interpersonal connectedness are sometimes different in computer‐mediated communication (CMC) and a new standard for transacting relational message exhange may be emerging.  相似文献

This paper seeks to investigate whether the Japanese government’s attempt to promote a ‘gender-equal’ society in recent decades and the improved status of women are reflected in patterns of gender representation in Japanese English as a foreign language textbooks. The study made an analysis of four popular series of English language textbooks published in 2011 for local Japanese students with corpus linguistic tools (e.g. concordancing, keyword in context) to investigate the ratio of female-to-male appearances, the extent of use of gender-neutral and gender-marked constructions, the common adjectives associated with women and men, the common address titles for reference to women, and the order of appearance of women and men. The findings revealed some evidence of gender equity, including common use of gender-inclusive vocabulary (e.g. salesclerk, waitperson) and the neutral address title Ms for women. The ‘male-first’ phenomenon, however, is still prevalent in contemporary Japanese textbooks, suggesting the secondary status of women. Variations were found in different series of textbooks pertaining to the representation of women and men in the domains of quantitative balance and gender stereotyping. It is suggested that specific guidelines be compiled by the education authorities to help textbook authors write educational materials that help promote a gender-fair society in Japan.  相似文献

Effects of problem-based learning as reported in curricular comparison studies have been shown to be inconsistent over different medical schools. Therefore, we decided to summarize effects of a single well-established problem-based curriculum rather than to add up sometimes-conflicting findings from different problem-based curricula. Effect sizes were computed for 270 comparisons. The results suggest that students and graduates from the particular curriculum perform much better in the area of interpersonal skills, and with regard to practical medical skills. In addition, they consistently rate the quality of the curriculum as higher. Moreover, fewer students drop out, and those surviving need less time to graduate. Differences with respect to medical knowledge and diagnostic reasoning were on average positive but small. These outcomes are at variance with expectations voiced in recent contributions to the literature. They demonstrate that constructivist curricula can have positive effects on learning even if they deemphasize direct instruction.  相似文献

Natural Language Processing (NLP) techniques have been successfully used to automatically extract information from unstructured text through a detailed analysis of their content, often to satisfy particular information needs. In this paper, an automatic concept map construction technique, Fuzzy Association Concept Mapping (FACM), is proposed for the conversion of abstracted short texts into concept maps. The approach consists of a linguistic module and a recommendation module. The linguistic module is a text mining method that does not require the use to have any prior knowledge about using NLP techniques. It incorporates rule-based reasoning (RBR) and case based reasoning (CBR) for anaphoric resolution. It aims at extracting the propositions in text so as to construct a concept map automatically. The recommendation module is arrived at by adopting fuzzy set theories. It is an interactive process which provides suggestions of propositions for further human refinement of the automatically generated concept maps. The suggested propositions are relationships among the concepts which are not explicitly found in the paragraphs. This technique helps to stimulate individual reflection and generate new knowledge. Evaluation was carried out by using the Science Citation Index (SCI) abstract database and CNET News as test data, which are well known databases and the quality of the text is assured. Experimental results show that the automatically generated concept maps conform to the outputs generated manually by domain experts, since the degree of difference between them is proportionally small. The method provides users with the ability to convert scientific and short texts into a structured format which can be easily processed by computer. Moreover, it provides knowledge workers with extra time to re-think their written text and to view their knowledge from another angle.  相似文献
