    A robust on-line learning algorithm for intelligent control systems
    (John Wiley & Sons Ltd, 2003) Efe, MÖ; Kaynak, O; Wilamowski, BM; Yu, XH
    This paper describes a novel error extraction approach for exploiting the strength of Levenberg-Marquardt (LM) optimization technique in intelligent control systems: Since the target value of the control signal is unknown, tuning of the controller parameters becomes a tedious task if the knowledge about the system and the environment is limited. The suggested methodology utilizes the sliding model control (SMC) technique. The error extraction scheme postulates the form of error on the applied control signal using the discrepancy from the prescribed reaching dynamics. The devised approach has been tested on the non-linear Duffing oscillator, which has been forced to follow a periodic orbit radically different from the natural one. The results obtained through a series of simulations have confirmed the high precision and robustness advantages without knowing the analytical details of the system under investigation. The issues of observation noise and the stability in the parametric space have approximately been addressed from the point of SMC perspective. Copyright (C) 2003 John Wiley Sons, Ltd.

    User Acceptance of Social Learning Systems in Higher Education: an Application of the Extended Technology Acceptance Model
    (Routledge Journals, Taylor & Francis Ltd, 2017) Akman, Ibrahim; Turhan, Cigdem
    This study aims to explore the users' behaviour and acceptance of social media for learning in higher educational institutions with the help of the extended Technology Acceptance Model (TAM). TAM has been extended to investigate how ethical and security awareness of users affect the actual usage of social learning applications. For this purpose, a survey was conducted and the Structural Equation Model approach was utilised to investigate the direct and indirect causal relationships among the constructs in the research model. Interestingly, the findings from the analysis reveal that, except ease of use', TAM's core and external constructs are significant predictors of actual behaviour towards using social media for learning.

    Using Learning Styles Theory in Engineering Education
    (Taylor & Francis Ltd, 2008) Cagiltay, Nergiz Ercil
    Studies have shown that, while learning different concepts, people sometimes take different approaches (learning styles). Accordingly, their performance reflected differently in their academic studies. With the effect of globalisation to the educational environments, the influence of individual learning styles on educational performance is getting more significant. In this study, a learning style assessment tool was used to examine the relationship between students' learning styles and their performance in engineering education programmes. At the beginning of the programme, 285 students' learning styles were measured using a learning style assessment tool. Four years after the engineering education, their performance in the programme was compared with their individual learning styles. This study shows that most of the students are assimilators. Divergers and convergers follow the assimilators. The number of accommodators is very limited. The relationship between engineering students' learning styles and their performance is found: assimilators and convergers performed better than the divergers and accommodators. The performance difference between assimilators and divergers is statistically significant. The results of this study show that the learning style theory is a potential tool for guiding the design and improvement of courses and helping students to improve their individual performance.

    Integration of Social Media Into Engineering Education: a Comparative Study on Perceptions of Faculty and Students
    (Tempus Publications, 2018) Turhan, Cigdem; Akman, Ibrahim; Software Engineering; Computer Engineering
    For a number of years, the effects of incorporating social media into education systems has invoked the interest of researchers, academicians and students. Yet, the enthusiasm of students in utilizing social media for learning is met with reluctance on the faculty's part in abandoning the traditional ways of teaching. This study compares the students' and faculty's acceptance of the utilization of social media in engineering education from different perspectives. A survey approach has been used for this purpose and 57 faculty and 85 students from the engineering faculties participated in the study. The research model used was tested using the least square regression technique. The results show existence of significant diversity between the faculty and students in the factors affecting the ethical usage. Concerning the general usage, this diversity exists in only the awareness. These results are expected to provide insight into the issues that act as barriers towards a more open, collaborative and learner-centered higher education platform.

    Use of Ict Tools and Their Effect on Teaching and Learning; Students' and Instructor's Views
    (Iated-int Assoc Technology Education & development, 2016) Cigdemoglu, Ceyhan; Akay, Hasan U.
    This study aims to reveal how instructors use ICT tools in their courses and determine what ICT tools they utilize as well as assessing the contribution of ICT to learning and teaching from both students' and instructors' perspectives. As a qualitative case study research, semi-structured interviews with instructors and focus group interviews with students were conducted. Both students' and instructors' responses indicated that there is a common belief that when these tools are employed, students' success will increase. Students verified that the use of educational technologies makes them to feel more successful. Instructors stated that such tools create more organized learning and alert instructor to search for best tools for students, and let course materials accessible whenever students need. Instructors stated that although there are number of factors impeding the whole utilization of ICT tools, they agree that traditional teaching is old fashioned and ineffective in these days. Based on the responses obtained, we can state that instructors lack in explaining and evaluating carefully the impact of ICT tools that may enhance or support students' in-depth learning. Their statements are generally anecdotal rather than data driven. Also, lack of motivation among faculty members due to time restrictions was perceived as obstacle to adopting ICT fully.
