“…Since computer prices decrease and it is possible to find easily variable versatile software programs, computeraided education has become a part of both classroom and laboratory experiments [12]. With new technological innovations, computers have been benefited as auxiliary equipments and teaching tools in many universities [13]. The uses of computers make a positive impact in lectures and laboratory work and also contribute economically towards mitigating the education cost [1].…”

Design and utilization of a Virtual Photovoltaic Systems Laboratory for undergraduate curriculum are introduced in this paper. The laboratory introduced in this study is developed to teach students the basics and design steps of photovoltaic solar energy systems in a virtual environment before entering the field. The users of the proposed virtual lab will be able to determine the sizing by selecting related parameters of the photovoltaic system to meet DC and AC loading conditions. Besides, the user will be able to analyze the effect of changing solar irradiation and temperature levels on the operating characteristics of the photovoltaic systems. Common DC bus concept and AC loading conditions are also included in the system by utilizing a permanent magnet DC motor and an RLC load as DC and AC loading examples, respectively. The proposed Virtual Photovoltaic Systems Laboratory is developed in Matlab/Simulink GUI environment. The proposed virtual lab has been used in Power Systems Lab in the Department of Electrical and Electronics Engineering at Karadeniz Technical University as a part of undergraduate curriculum. A survey on the students who took the lab has been carried out and responses are included in this paper.

Computers are widely used for educational purposes. Multimedia tools and simulations are mostly preferred for learning especially hard and complex structures in technical field and hardly realized experiments in laboratory environment. Besides, supporting theoretical knowledge with practical applications is crucial in engineering education. But, effects of negative conditions such as hardware deficiency (experimental gadgets, measuring instruments, etc.) in education environment, high number of students, less number of educators can be diminished with concepts which are distance education, computer‐aided education, etc. In this study, web‐based educational tool which is oriented to signals and systems subjects/courses is realized. This tool provides learning of signals and systems subjects with its subject descriptions, solved/unsolved problems, animations, simulations, interactive simulators, real‐time applications, general exams, online communication/support, and new educational strategy in easy, simple, and effective way. Usability and educational contribution of realized study was inspected with questionnaires which were filled anonymously by 110 students in Uludag University and assessed according to SUS and Likert scales.

“…Finally, there are many software learning tools fully oriented to virtual laboratories, but they can be also useful for complementing real-laboratory activities; for example [36][37][38][39][40][41], which are not web-based (although [37,40] are available through the Internet), as well as [10,17,42,43], web-based. Particularly, among the mentioned articles we remark the contributions to practical applications of Digital Signal Processing specifically in the acoustics laboratory, namely [20][21][22]24,35], as well as Digital Signal Processing for images or in general, namely [23,[25][26][27][28]32,39,41,42].…”
