In this work, we propose a novel structure of solar cell based on copper-indium-gallium-diselenide CuIn1−xGaxSe2 (CIGS) absorber layer by using SCAPS-1D (Solar Cell Capacitance Simulator of the University of Gent). This numerical simulation has been used to explore the possibility of higher efficiency and stable CdS/CIGS cell structures with (ZnO) as window layer, and (CdS) a buffer layer, (CIGS)...
The word “Cloud” has become more and more popular these days. One of its applications, Cloud for manufacturing, is also proposed as we called Cloud Manufacturing. It is realized by setup a public service cloud platform which shares manufacturing resources and knowledge. As the big data era comes, the amount of both resources and knowledge in the platform may increase much more rapidly than ever before...
Open Education is changing the educational paradigm. The consolidation of the OpenCourseWare initiative, supported by the top universities of the World, and the revolution generated in the recent years through the emergence of Massive Open Online Courses, present a new educational scenario for teachers, students and institutions. This new environment has furthered the use of e-learning, not only because...
Design experience coursework for first-year engineering and computer science students is not new. These experiences are often team-based and typically focus extensively on the technical aspects of the project, while the behavioral and interpersonal aspects sometimes go unnoticed. Here, we report on a novel organization for an introduction to engineering design course that provides direct and proactive...
This paper proposes a new web platform for educational activities for helping in the experimental work and the professional development of engineering students. The fundamental idea is to connect conventional theory study spaces, such as the classroom and home, through the web platform proposed with experimental training tools in the hands-on laboratory. What is proposed is a new focus on classroom...
Well-designed formative feedback can enhance both instructor teaching and student learning with "two-way" feedback. The project goal was to use web-enabled tools and resources that facilitate the strategies, practices, and assessments that use frequent formative feedback to improve student attitude, learning, and achievement. The research question is, "What is the effect of formative...
As engineering disciplines evolve, universities are challenged to continually incorporate new material into the undergraduate curriculum. Traditionally, the two primary methods of incorporating new material are to either change the curriculum of a specific class or hire a new instructor to teach a new class. In our paper, we introduce a new model for introducing skills and tools necessary for undergraduates...
Advances in technology have created unique opportunities for teaching digital design courses. Students in such courses no longer need to be present in the laboratory in order to obtain practical hands on experience and master the course material as students can complete laboratory assignments at home using relatively inexpensive commercial off-the-shelf development platforms and free software design...
The Open University of Israel (OUI) is an institution of higher education which has an open admissions policy and is based primarily on distance learning. The CSI course at the OUI is similar to introductory computing courses at other universities in Israel and worldwide. Over the years, we have composed some tens of CSI final exams and collected data related to the exams. Since there is a high dropout...
This paper describes our continuous effort to implement a flipped classroom approach to teach an Electric Circuits course. The main motivation behind adopting this approach is to allow more time for in-class problem solving and, therefore, improving students' problem solving skills. Prior to each scheduled class meeting, students are asked to watch a recorded short lecture, which covers the topics...
Students' goal orientations impact their self-regulation, engagement, and achievement in post-secondary STEM courses. But, how students' goal orientations change across a semester and the impacts of these changes have not been extensively studied. Study purposes were to investigate goal orientation change across the semester, associations of goal change with achievement and self-regulation, and associations...
One of the major challenges facing the growth of South Africa, the largest economy in Africa and a member of the five major emerging national economies (BRICS) of the world, is unemployment. While there are other factors influencing unemployment, high dropout rates in universities are seen as a definite contributor to this challenge. Reflection and reflective practices have been extensively researched...
After the promising results of the pilot phase of "Brain-based Programming", a new teaching concept for introductory programming courses based on neurodidactical principles, the empirical study continues this year in three groups. The results obtained so far in the current semester at our university are promising, too: In the first exams the students of the experimental groups achieved significantly...
We present a synopsis of instructor experience on the mastery learning approach as implemented in our school for key fundamental engineering courses. The mastery learning approach revolves around the idea of dividing the course into modules, each module culminates in an exam comprised of 2 or 3 problems where each problem tests one important concept. For each exam, a student can make up to 3 attempts,...
This paper discusses the effects of using frequent online quizzes as a replacement for homework in an Electric Circuits Course. The results of two experiments show that performance on these quizzes is correlated with performance on course exams, conceptual understanding of the material, and problem solving ability. These results do not appear to be correlated with prior knowledge, grit, or self-efficacy.
A National Science Foundation (NSF) sponsored project was initiated in 2011 at the Department of Mechanical and Manufacturing Engineering (MME), Miami University, with the aim of creating online learning modules to increase the efficacy of the coursework. The modules were designed to instil proficiency in computational and experimental analysis, and were grouped along five thematic lines in the form...
The primary goal of this mini-workshop is to assist participants in creating Inquiry Based Learning Activities (IBLAs) that promote better conceptual understanding for their students. This is part of more general goal of transforming engineering classrooms into more interactive formats that promote student engagement and lead to improved student outcomes. Specifically the workshop will introduce participants...
In this study, we report on the student experience at Olin College, a small undergraduate university in the United States with an explicit mission to transform engineering education. We employ a highly narrative approach to situate students' individual experiences within their larger learning trajectories and use them as a lens through which we view the accounts of their time at college. We highlight...
