Student engagement scale: development,reliability and validity     

Selim Gunuc  Abdullah Kuzu 《Assessment & Evaluation in Higher Education》2015,40(4):587-610

In this study, the purpose was to develop a student engagement scale for higher education. The participants were 805 students. In the process of developing the item pool regarding the scale, related literature was examined in detail and interviews were held. Six factors – valuing, sense of belonging, cognitive engagement, peer relationships (emotional engagement-I), relationships with faculty members (emotional engagement-II) and behavioural engagement within the scope of the components of campus engagement and class engagement – made up of 41 items were identified. The total variance explained was 59%. A higher student engagement score was regarded as an indicator that the student had a high level of engagement with the university, campus and class, while a lower score demonstrated that the student’s engagement with the campus and class was weak or that disengagement could occur.  相似文献   

A stochastic multi-parameters divergence method for online auto-tuning of fractional order PID controllers     

Celaleddin Yeroğlu  Abdullah Ateş 《Journal of The Franklin Institute》2014

This paper presents a stochastic multi-parameters divergence method for online parameter optimization of fractional-order proportional–integral–derivative (PID) controllers. The method is used for auto-tuning without the need for exact mathematical plant model and it is applicable to diverse plant transfer functions. The proposed controller tuning algorithm is capable of adaptively responding to parameter fluctuations and model uncertainties in real systems. Adaptation skill enhances controller performance for real-time applications. Simulations and experimental observations are carried on a prototype helicopter model to confirm the performance improvements obtained by the online auto-tuning of fractional-order PID structure in laboratory conditions.  相似文献   

The application of workflow management to digital heritage resources     

Abdullah Al-Barakati  Martin White  Zeeshan Patoli 《International Journal of Information Management》2014

Recent years have witnessed a noticeable proliferation in Digital Library Systems (DLSs) and their specialized form represented in Digital Heritage Resources (DHRs). DHRs usually manage a complex and varied mix of digital heritage objects of different types and formats. They tend to be complex in nature and usually involve complex, simultaneous and intersecting workflows. As a result, DHRs impose implementation challenges on any solutions that aim to manage their workflows. Thus, despite the proliferation of DHRs, it is a noteworthy trend that there is a general lack of workflow management solutions that can be utilized in such systems. As a research area that is rarely covered, this paper therefore presents the design and development of a novel Workflow Management System (WfMS) built to integrate with DHRs specifically, and DLSs in general. In this context, an experimental WfMS aimed to test the validity of workflow management integration with DHRs. The devised WfMS was built as a workflow management solution that can adequately address the specific hurdles imposed by DHR implementations. Additionally, a novel DHR implementation framework called DISPLAYS (Digital Library Services for Playing with Antiquity and Shared Heritage) is presented as a test bed for the proposed WfMS.  相似文献

Students’ Perceptions of Their Science Teachers’ Pedagogical Content Knowledge     

Lilia Halim  Sharifah Intan Sharina Syed Abdullah  T. Subahan Mohd Meerah 《Journal of Science Education and Technology》2014,23(2):227-237

Pedagogical content knowledge (PCK) is a type of teacher knowledge to be developed by a teacher. PCK is said to contribute to effective teaching. Most studies investigated the development of PCK and its influence on students’ learning from the teachers’ perspectives. Only a limited number of studies have investigated the components of science teachers’ PCK that helped students’ learning from the perspective of students. Thus, it is the aim of this study to investigate the level of science teachers’ PCK from students’ perspective, in particular whether or not students of different achieving ability had different views of teachers’ PCK in assisting their learning and understanding. Based on the PCK research literature, six components of PCK have been identified, which were as follows: (1) subject matter knowledge, (2) knowledge of teaching strategies, (3) knowledge of concept representation, (4) knowledge of teaching context, (5) knowledge of students, and (6) knowledge of assessment in learning science. A questionnaire consisting of 56 items on a five-point Likert-type scale were used for data collection from 316 Form Four students (16 years old). One-way analysis of variance revealed that the differences in science teachers’ PCK identified by students of different achieving abilities were statistically significant. Overall, students of various academic achieving abilities considered all the components of PCK as important. The low-achieving students viewed all the components of PCK as being less important compared to the high and moderate achievers. In particular, low-achieving students do not view ‘knowledge of concept representation’ as important for effective teaching. They valued the fact that teachers should be alert to their needs, such as being sensitive to students’ reactions and preparing additional learning materials. This study has revealed that PCK of science teachers should be different for high and low-achieving students and knowledge of students’ understanding plays a critical role in shaping teachers PCK.  相似文献   

Characteristics of the home context for the nurturing of gifted children in Saudi Arabia     

Sascha Hein  Mei Tan  Abdullah Aljughaiman 《High Ability Studies》2014,25(1):23-33

This study investigates factors in the home environment and their influence on children’s analytical, creative, and practical skills. A sample of 294 gifted children (195 male) was recruited from grades 4–7 in Saudi Arabia, where the family context is highly influenced by the principles of Islam. Results did not confirm the effect of birth order, but showed that (1) mother’s education was an important factor for gifted children’s creativity; (2) the number of boys in the family was negatively associated with gifted boys’ creativity (r?=??.21); and (3) Quran-related learning experiences were positively related to gifted girls’ analytical (r?=?.46) and creative (r?=?.42) skills. Implications for understanding non-Western environments for gifted children are discussed.  相似文献   

Study of cellulolytic soil fungi and two nova species and new medium     

Khalid M  Yang WJ  Kishwar N  Rajput ZI  Arijo AG 《Journal of Zhejiang University. Science. B》2006,7(6):459-466

This study is aimed at identifying and determining the percentage of occurrence frequency of cellulose decomposing soil fungi. The soil samples were inoculated into culture plates prepared in Sabouraud medium under sterilized conditions and incubated at 30 ℃ for 4 to 7 d. The identified fungal species were incubated in self-designed cellulose medium for testing their cellulolytic ability. Forty-two species, including2 nova species, representing sixteen genera showed growth and sporulation in the cellulose medium. Most of the isolated species were from genus Aspergillus and Penicillium. Aspergillus niger and Mucor hiemalis showed highest occurrence frequency （45% and 36% respectively）, as these species were collected from about 80% of soil samples. Being agar free and cheaper, the new fungal medium designed showed results equivalent to Sabouraud medium.  相似文献   

Measuring the outcomes of information literacy: Perception vs evidence-based data     

Szarina Abdullah 《International Information and Library Review》2010,42(2):98-104

This paper emphasizes the significance of using evidence-based data (EBD) in measuring the outcomes of Information Literacy programs. The paper highlights the differences between data collected from evidence which is based on the actual performance of individuals who have gone through IL programs, as opposed to just perception-based data (PBD) which is predicated primarily on opinions (whether laymen or experts). The author contends that the outcomes of IL programs can be better measured based on the tangible performance of individuals who have completed an IL program, rather than by the perceptions of students or librarians. Evidence-based data are particularly useful for managers because they provide concrete evidences about specific areas of strengths and weaknesses that need improvement, and/or are otherwise valuable in planning and implementing IL programs in general.  相似文献
