University Programme Preferences of High School Science Students in Singapore and Reasons that Matter in their Preferences: A Rasch analysis     

Pey-Tee Oon 《International Journal of Science Education》2013,35(2):367-388

This study explored an under-researched area in science education—the university programmes preferred by high school students who take physical science subjects and the reasons that matter in their preferences. A total of 1,071 upper secondary and pre-university students in Singapore, who take physical science subjects among their range of subjects, participated in this study. A survey method was adopted and the Rasch model was used to analyse the data. Overall, Business Studies was ranked as the predominant choice; nonetheless, scientific programmes such as Science, Engineering, and Mathematics are generally still well liked by the students. When gender differences were examined, we found that students largely followed gender-typical programme preferences, in which males tend to incline towards Engineering while females tend to incline towards Arts and Social Sciences. Students prefer a university programme based on their individual interest and ability, with career aspiration and remuneration coming next. Interestingly, females place greater emphasis on career aspiration than males. Some implications of the study are discussed.  相似文献

Beliefs of teachers in Italian schools concerning the inclusion of disabled students: a Q‐sort analysis     

Franco Zambelli  Raffaele Bonni 《欧洲特需教育杂志》2013,28(3):351-366

This paper presents a course of research into the beliefs of class teachers concerning the scholastic integration of children with disabilities. In the current situation in Italy, due to limited specialist training, the attitudes that teachers develop can constitute an obstacle to the full realization of scholastic integration. Of the 23 teachers who took part in the study, conducted using the Q‐sort methodology, some had direct experience with scholastic integration (with opinions both positive and negative); and others had no direct experience (but also had both positive and negative opinions). Using the Q‐sort system, the paper sets out to verify whether effectively the simple manifestation of positive or negative beliefs in relation to inclusion on the part of the teachers (whether they had direct experience or not) could be confirmed, and whether it lent itself to being developed in reference to specific areas of scholastic experience. From the factorial analysis of the Q‐data, four factors emerged that confirm our hypothesis regarding the existence of different beliefs among teachers.  相似文献   

Talking about the test. Boundary work in primary school teachers' interactions around national testing of student performance     

《Teaching and Teacher Education》2013

There is currently a strong belief in accountability as a policy of action and standardized testing has been implemented in several countries. This article examines tensions that occur in meetings when primary school teachers in Norway discuss national testing, and how these are handled. In particular, tensions revolve around what is seen as internal (teachers' everyday work) and external (policies and practices outside the main frame of teaching). Even though national testing is mainly seen as external to teachers' work, teachers involve in boundary work and reshape professional discourse in order to create relevance and maintain legitimacy following new expectations.  相似文献   

Evaluating the Comparability of Paper‐ and Computer‐Based Science Tests Across Sex and SES Subgroups     

Jennifer Randall  Stephen Sireci  Xueming Li  Leah Kaira 《Educational Measurement》2012,31(4):2-12

As access and reliance on technology continue to increase, so does the use of computerized testing for admissions, licensure/certification, and accountability exams. Nonetheless, full computer‐based test (CBT) implementation can be difficult due to limited resources. As a result, some testing programs offer both CBT and paper‐based test (PBT) administration formats. In such situations, evidence that scores obtained from different formats are comparable must be gathered. In this study, we illustrate how contemporary statistical methods can be used to provide evidence regarding the comparability of CBT and PBT scores at the total test score and item levels. Specifically, we looked at the invariance of test structure and item functioning across test administration mode across subgroups of students defined by SES and sex. Multiple replications of both confirmatory factor analysis and Rasch differential item functioning analyses were used to assess invariance at the factorial and item levels. Results revealed a unidimensional construct with moderate statistical support for strong factorial‐level invariance across SES subgroups, and moderate support of invariance across sex. Issues involved in applying these analyses to future evaluations of the comparability of scores from different versions of a test are discussed.  相似文献   

Collaborative risk method for information security management practices: A case context within Turkey     

Sevgi Ozkan  Bilge Karabacak 《International Journal of Information Management》2010

In this case study, a collaborative risk method for information security management has been analyzed considering the common problems encountered during the implementation of ISO standards in eight Turkish public organizations. This proposed risk method has been applied within different public organizations and it has been demonstrated to be effective and problem-free. The fundamental issue is that there is no legislation that regulates the information security liabilities of the public organizations in Turkey. The findings and lessons learned presented in this case provide useful insights for practitioners when implementing information security management projects in other international public sector organizations.  相似文献
