Abdullah Al-Sakkaf  Mazni Omar  Mazida Ahmad 《Computer Science Education》2019,29(2-3):283-309

ABSTRACT

Background and Context: In spite of the decades spent developing software visualization (SV), doubts still remain regarding their effectiveness. Furthermore, student engagement plays an important role in improving SV effectiveness as it is correlated with many positive academic outcomes. It has been shown that the existing SV has failed to engage students effectively.

Objective: Therefore, there is a need to understand the theories behind SV design from the engagement perspective to produce a roadmap for future tool construction. The aim of this study was to identify the theories have been used in literature to explain or construct student engage- ment with SV in computer science courses for novices.

Method: We performed a systematic literature review that identified a total of 58 articles published between 2011 and 2017, which were then selected for the study. However, among them, only 18 articles had discussed their theoretical framework.

Findings: The results of this study show a richness in the theoretical framework obtained from different disciplines, however, constructivism is still dominant in the computing education research (CER) domain. It is evidently clear from the findings that the theories generated from the CER domain are needed to enhance the effectiveness of SV.

Implications: As a result of this review, we suggest several design principles and engagement attributes to be considered while creating an engaging SV.  相似文献

Recent improvements in three‐dimensional (3D) virtual modeling software allows anatomists to generate high‐resolution, visually appealing, colored, anatomical 3D models from computed tomography (CT) images. In this study, high‐resolution CT images of a cadaver were used to develop clinically relevant anatomic models including facial skull, nasal cavity, septum, turbinates, paranasal sinuses, optic nerve, pituitary gland, carotid artery, cervical vertebrae, atlanto‐axial joint, cervical spinal cord, cervical nerve root, and vertebral artery that can be used to teach clinical trainees (students, residents, and fellows) approaches for trans‐sphenoidal pituitary surgery and cervical spine injection procedure. Volume, surface rendering and a new rendering technique, semi‐auto‐combined, were applied in the study. These models enable visualization, manipulation, and interaction on a computer and can be presented in a stereoscopic 3D virtual environment, which makes users feel as if they are inside the model.

Anatomy "steeplechase" online: necessity sometimes is the catalyst for innovation     

Inuwa IM  Al Rawahy M  Taranikanti V  Habbal O 《Anatomical sciences education》2011,4(2):115-118

In most medical schools, summative practical examination in Anatomy usually takes the format of a “steeplechase” (“spotters” or “bell ringers”) conducted in the gross anatomy laboratory using cadaveric material and prosected specimens. Recently, we have started to administer similar examinations online using the quiz facility in WebCT? and Moodle?. This article chronicles how we conceived and developed this method within the peculiar nature of our medical school setting. Over a five year period, practical summative examinations were organized as “steeplechase” online. The online examinations were administered using WebCT? and later Moodle? learning management software. Assessment “objects” were created from the materials available for anatomy teaching. These were digital images of cadaveric materials, radiological, and prosected specimens. In addition, short video clips of 30 seconds duration demonstrating muscle action were produced. These objects were optimized for online viewing and then uploaded onto the learning management software. A bank of questions (multiple choice or short answer type) was then created and linked to the assessment objects. These were used in place of the steeplechase in the computer laboratory. This method serves a crucial purpose in places like ours where continuous availability of human cadavers is impossible. Although time consuming initially, once questions are setup online, future retrieval, and administration becomes convenient especially where there are large batches of students. In addition, the online environment offers distinct advantages with regards to image quality, psychometric analysis of the examination and reduction of staff preparation time compared to traditional “steeplechase.” Anat Sci Educ 4: 115–118, 2011. © 2010 American Association of Anatomists.  相似文献   

Robust FOPID stabilization of retarded type fractional order plants with interval uncertainties and interval time delay     

Majid Ghorbani  Mahsan Tavakoli-Kakhki  Ali Akbar Estarami 《Journal of The Franklin Institute》2019,356(16):9302-9329

This study investigates the robust stability of the retarded type of interval fractional order plants with an interval time delay. To this end, the characteristic quasi-polynomial is divided into two terms. The first term is simply the denominator interval polynomial of the open loop system and the second term is the multiplication of the interval delay term in the numerator of the open loop system which is an interval polynomial. Each of these two terms of the characteristic quasi-polynomial makes their own value sets in the complex plane for a given frequency. In this paper, based on these two value sets and by using the zero exclusion principle, the robust stability of the closed loop system by applying a FOPID controller is analyzed. Finally, two numerical examples and an experimental verification are provided to demonstrate the effectiveness of the proposed method in the robust stabilization of fractional order plants with interval uncertainties and interval time delay.  相似文献

Bond graph formulation of an optimal control problem for linear time invariant systems   总被引：1，自引：0，他引：1  

Wilfrid Marquis-Favre  Omar Mouhib 《Journal of The Franklin Institute》2008,345(4):349-373

A recent communication has proposed a conjectural procedure for representing a category of optimal control problems in bond graph language [W. Marquis-Favre, B. Chereji, D. Thomasset, S. Scavarda, Bond graph representation of an optimal control problem: the dc motor example, in: ICBGM’05 International Conference of Bond Graph Modelling and Simulation, New Orleans, USA, January 23-27, 2005, pp. 239-244]. This paper aims at providing a fundamental theory for proving the effectiveness of this procedure. The class of problem that the procedure can deal with has been extended. Its application was formerly restricted to linear time invariant siso system. The systems considered now are linear time invariant mimo systems. The optimization objective is the minimization of dissipation and input. The developments concerning the optimal control problem are based on the Pontryagin maximum principle and the proof of the effectiveness of the procedure makes a broad use of the port-Hamiltonian concept. As a result, the bond graph representation of the given optimization problem enables the analytical system, which provides the optimal solution, to be derived. The work presented in this paper is the first step in research with perspectives towards formulating dynamic optimization problems in bond graph and, towards coupling this formulation with a sizing methodology using bond graph language and a state-space inverse model approach. This sizing methodology, however, is not the topic of this paper and thus is not presented here.  相似文献

Information literacy education: Applications of mediated learning and multiple intelligences     

Intan Azura Mokhtar  Shaheen Majid  Schubert Foo 《Library & information science research》2008

Research has shown that mastering information literacy (IL) competencies helps students perform better academically or otherwise. However, there is limited evidence that indicates a relationship between IL teaching methods and IL competencies. This study investigates the impact of IL teaching that incorporates appropriate pedagogical approaches on students' applicability of IL competencies. The study was carried out in four secondary schools in Singapore. Students were organized into groups of five and were assigned a group project. Those in the experimental sub-clusters were exposed to various intervention approaches, while the control sub-clusters were left on their own to carry out the project. Three independent, neutral teacher-examiners evaluated the results of the group reports and projects. The results showed significant differences in the achievements of students in the experimental groups that underwent both interventions as compared to the control groups.  相似文献   

Students’ assessment of interactive distance experimentation in nuclear reactor physics laboratory education     

Salaheddin Malkawi  Omar Al-Araidah 《European Journal of Engineering Education》2013,38(5):512-518

Laboratory experiments develop students’ skills in dealing with laboratory instruments and physical processes with the objective of reinforcing the understanding of the investigated subject. In nuclear engineering, where research reactors play a vital role in the practical education of students, the high cost and long construction time of research reactors limit their accessibility to few educational programmes around the world. The concept of the Internet Reactor Laboratory (IRL) was introduced earlier as a new approach that utilises distance education in nuclear reactor physics laboratory education. This paper presents an initial assessment of the implementation of the IRL between the PULSTAR research reactor at North Carolina State University in the USA and the Department of Nuclear Engineering at Jordan University of Science and Technology (JUST) in Jordan. The IRL was implemented in teaching the Nuclear Reactor laboratory course for two semesters. Feedback from surveyed students verifies that the outcomes attained from using IRL in experimentation are comparable to that attainable from other on-campus laboratories performed by the students.  相似文献
