Diagnosing Competency Mastery in Science: An Application of GDM to TIMSS 2011 Data     

Masoud Kabiri  Mahmood Ghazi-Tabatabaei  Abbas Bazargan  Mohsen Shokoohi-Yekta  Kamal Kharrazi 《教育实用测度》2017,30(1):27-38

Numerous diagnostic studies have been conducted on large-scale assessments to illustrate the students’ mastery profile in the areas of math and reading; however, for science a limited number of investigations are reported. This study investigated Iranian eighth graders’ competency mastery of science and examined the utility of the General Diagnostic Model (GDM) to produce diagnostic information using TIMSS 2011 data. Eight diagnostic attributes were extracted, using documentary analysis of the major large-scale assessment frameworks, including basic science knowledge, using models, reasoning, using science, representing data, explaining of phenomena, predicting, and scientific inquiry. These attributes were then assigned to each item in order to construct the Q matrix, through focus group discussions, survey of head science teachers, think-aloud verbal protocol, and analysis of written answers. Results show the utility of GDM to generate rich diagnostic information for a national large-scale assessment. Moreover, the findings indicated that students performed relatively well in using science, but performed weakly in reasoning, explaining of phenomena, and scientific inquiry, which all required complex skills and higher-order thinking abilities.  相似文献   

Implementation of co-teaching approach in an inclusive classroom: overview of the challenges,readiness, and role of special education teacher     

Abdul Rahim Hamdan  Muhammad Khairul Anuar  Aqeel Khan 《Asia Pacific Education Review》2016,17(2):289-298

The objective of this study was to determine the relationship aspect of the challenge, readiness, and the role of special education teacher (SET) in implementing common approaches in inclusive classrooms. Experiences as a moderator were used to see the effect of the co-teaching component. This study used a sampling method that involved 240 respondent’s representatives of the population of SET in Malaysia. The findings of this study showed that there was a high positive tendency in choosing the approach that is likely to progress than the existing ones. In this area, there were challenges and readiness of positive selection than teacher experience. Overall, this study could impact the implementation of co-teaching approach than the implementation of the existing programme.  相似文献

Use of digital media and demand for digitized contents in higher education sector of Pakistan     

Muhammad Rafiq  Kanwal Ameen 《International Information and Library Review》2012,44(3):116-122

The use of digital media is on rise around the world and same phenomenon is emerging in Pakistan. The study was intended to explore the use of digital media and demand for digitized contents in higher education sector of Pakistan. The research questions were answered by a comprehensive literature review along with semi-structured in-depth interviews of 25 library experts. The findings conferred that the use of digital media in higher education is on rise and demand for digitized contents is growing increasingly. The findings of the study made a good case for the libraries to focus more on acquisition of information resources in digital formats as well as initiate digitization initiatives.  相似文献   

Automating the Construction of Internet Portals with Machine Learning   总被引：11，自引：0，他引：11  

Andrew Kachites McCallum  Kamal Nigam  Jason Rennie  Kristie Seymore 《Information Retrieval》2000,3(2):127-163

Domain-specific internet portals are growing in popularity because they gather content from the Web and organize it for easy access, retrieval and search. For example, www.campsearch.com allows complex queries by age, location, cost and specialty over summer camps. This functionality is not possible with general, Web-wide search engines. Unfortunately these portals are difficult and time-consuming to maintain. This paper advocates the use of machine learning techniques to greatly automate the creation and maintenance of domain-specific Internet portals. We describe new research in reinforcement learning, information extraction and text classification that enables efficient spidering, the identification of informative text segments, and the population of topic hierarchies. Using these techniques, we have built a demonstration system: a portal for computer science research papers. It already contains over 50,000 papers and is publicly available at www.cora.justresearch.com. These techniques are widely applicable to portal creation in other domains.  相似文献   

Attitudes of Kuwaiti parents toward physical punishment of children     

Fatma S Qasem  Ahlam A Mustafa  Nafeesa A Kazem  Nasra M Shah 《Child abuse & neglect》1998,22(12):1189-1202

Objective: The major aim was to describe parental attitudes to physical punishments and examine their sociodemographic correlates. A related aim was to assess the association of parents’ own experience of physical punishment with attitudes to punishment of children.Method: A cross-sectional survey was conducted during the second week of December, 1996 in five general clinics covering the major administrative areas of Kuwait: 337 Kuwaiti mothers and fathers with at least one living child were contacted; 95% were successfully interviewed using a structured questionnaire.Results: Eighty-six percent of parents agreed with physical punishment as a means of child disciplining. Agreement with punishment was higher in case of serious misbehaviors such as stealing (63%), sniffing glue and using drugs (77%). Multiple regression results showed that parent’s lower level of education and Bedouin ethnicity were positively associated with agreement on physical punishment. Larger percentages of parents who had experienced physical punishments themselves agreed with such punishment to discipline their children, but this was not statistically significant.Conclusions: In recent years education has become widespread for both sexes. An inverse association between educational level and agreement on physical beating suggest that attitudes to this form of child disciplining are changing. Those with a Bedouin ethnic background still adhere more strictly to the traditional forms of child disciplining including physical beating. There is a need for conducting research on the possible negative psychosocial impacts of physical punishment in view of findings from other countries.  相似文献
