Field Association (FA) terms are a limited set of discriminating terms that can specify document fields. Document fields can be decided efficiently if there are many relevant FA terms in that documents. An earlier approach built FA terms dictionary using a WWW search engine, but there were irrelevant selected FA terms in that dictionary because that approach extracted FA terms from the whole documents. This paper proposes a new approach for extracting FA terms using passage (portions of a document text) technique rather than extracting them from the whole documents. This approach extracts FA terms more accurately than the earlier approach. The proposed approach is evaluated for 38,372 articles from the large tagged corpus. According to experimental results, it turns out that by using the new approach about 24% more relevant FA terms are appending to the earlier FA term dictionary and around 32% irrelevant FA terms are deleted. Moreover, precision and recall are achieved 98% and 94% respectively using the new approach. 相似文献

The aims of this study are to: (a) assess if cognitive self-concept (competence) and affective self-concept in mathematics and science are different constructs, (b) evaluate the construct validity of self-concept in the context of conflation and separation, and (c) test if the relationships among cognitive and affective variables are invariant across gender. The data for this study were obtained from the Trends in International Mathematics and Science Study 2007 database. Data about 2,687 out of 4,099 eighth grade Saudi students were subject to various analyses. The variables used in this study were mathematics and science self-concepts, and mathematics and science subject value as part of the Students Background Questionnaire. The relationships among constructs were examined with the use of SPSS16 and the structural equation modeling software, AMOS16. The results demonstrated that subject value and self-concept were different constructs. Also, the results demonstrated that cognitive and affective self-concepts were independent, but strongly related constructs, and the structure of the construct was clearer when self-concept was separated into cognitive and affective components than when it was conflated. The relationships among cognitive, affective, and subject value in mathematics and science were invariant across gender. However, their relationships with achievement were not invariant across gender. 相似文献

The Correlation between Final Grade Score,Attendance and Homework in the Performance of CED Students
Adel S. Aldosary 《European Journal of Engineering Education》1995,20(4):481-486
The student performance of 152 College of Environmental Design students from 10 courses were analyzed for possible correlation between the final score, class attendance and the homework assignments. It is widely believed that student performance in a course is strongly related to attendance level. However, the results of this study showed a much stronger correlation between the final score and the homework performance in a given course than between the final score and the attendance level. This demonstrates that we ought to consider placing a much heavier weight on homework and assignment as a percentage of the final score, as well as load of assignments, than we currently do. We may also consider relaxing some of our stronger policies on attendance. 相似文献

This study investigated the knowledge and attitudes of Jordanian school counselors toward diabetes mellitus. A sample of 295
counselors completed a questionnaire consisting of two parts concerning knowledge and attitudes. The face validity of the
questionnaire was assessed using an informed panel of judges, and its reliability was established using the test- re-test
method. Results showed that counselors as a whole had a moderate level of knowledge about diabetes. This level of knowledge
was related to counselor gender (females were more knowledgeable than males) and to knowing a person with diabetes, but not
to counselor age. Results also showed that counselors showed favorable attitudes toward students with diabetes. Knowing a
student with diabetes had no influence on attitudes. 相似文献

A cross-cultural comparison of Kuwaiti and British citizens' views of e-government interface quality
It is difficult to conceive how Web users from different cultures can be encouraged to reap the benefits of an e-government initiative when its portal is suffering from culture-indifferent interface quality. Thus far, the e-government literature not only has paid scanty attention to web evaluation issues but also has been slow to embarking on cross-cultural research. As an attempt to address this concern, this investigation introduces an augmented approach to analyze cross-cultural website quality. The proposed approach consists of three parts: 1) a qualitative study of the website using content analysis, 2) an empirical evaluation using traditional statistical methods of perceptions of website users, and 3) a “persuasive quality gap” analysis that examines the gap between the composite scores of perceived importance and performance of quality attributes across the studied two cultures. These analyses were used to identify cross-cultural differences between Kuwaiti and British users' perceptions of e-government quality attributes. While the findings showed no significant differences between Kuwaiti and British users in terms of important quality features, the results revealed significant variations between the two groups in terms of perceived performance of quality attributes. Moreover, although the findings showed marginal support for the existence of differences between the two samples in terms of persuasive quality features, a post-hoc analysis of the persuasive quality gap revealed a need to consider not only important and/or high performing characteristics but also persuasive features to fully understand cross-cultural e-government quality variations. The author discusses the implications of these results for e-government design practices and future research. 相似文献

Urban High School Students’ IT/STEM Learning: Findings from a Collaborative Inquiry- and Design-Based Afterschool Program 总被引：1，自引：0，他引：1

This exploratory study examines the impact of a collaborative inquiry- and design-based afterschool program on urban high school students’ IT/STEM learning—using information technology (IT) within the context of science, technology, engineering, and mathematics (STEM). The study used a mixed methods design, involving 77 participants within two cohort groups, each participating in an eighteen-month intervention period. Data were collected from the pre- and post-surveys, analysis of the participants’ IT/STEM projects, external evaluation reports, and follow-up interviews. Findings indicate that the program had a significant impact on students’ technology and IT/STEM skills, frequency of technology use, and understanding of IT use in STEM-oriented fields. Some degree of impact on attitude changes toward IT/STEM and career aspirations in these fields was also in evidence. The study demonstrates that IT/STEM experiences supported through technology-enhanced, inquiry- and design-based collaborative learning strategies have significant impact on urban high school students’ IT/STEM learning. Effect of afterschool programs on attitude changes and IT/STEM-related career aspirations of urban high school students are recommended areas of further investigation. 相似文献
