Arts College for(W), Dindigul – 01 Abstract Open content and open access to resources are important factors in the innovation of Computer Science education. This paper presents a study aimed at gaining an understanding of the needs of Computer Science educators in terms of Open Educational Resources (OER): what kind of resources they need, when they need them, how they use them, and what are the barriers and the enablers for using OER The work contributes to the research on OER utilization and discovery. The aim is to raise the awareness and promote a practical transition process towards an adequate model that aligns the interests of all stakeholders. Keywords: Open education, Open Educational Resources, Computer Science education, Open Source tools. 1. Introduction The world is embracing an open education model. The important factors in the innovation of computer science education are open licensed educational materials and open access. Open Educational Resources (OERs) or any type of educational materials that are in the public domain or introduced with an open license that permits their free use and re-purposing by others. The nature of these open materials means that anyone can legally and freely copy, use, adapt and reassure them. OERs range from textbooks to curricula, syllabi, lecture notes, assignments, tests, projects, audio, video and animation. The Open Educational Resources (OER) movement began in 2001 when the Hewlett and Mellon foundations jointly funded MIT’s Open Course Ware (OCW) initiative. Open education is the simple and powerful idea that the world’s knowledge is a public good and that technology in general and the Web in particular provide an extraordinary opportunity for everyone to share, use, and reuse knowledge. OER are teaching, learning and research resources that reside in the public domain or have been released under an intellectual property license that permits their free use and re-purposing by others. It includes full courses, course materials, modules, textbooks, streaming videos, tests, software, and other tools, materials, or techniques used to support access to knowledge. Despite some significant advances in recent years, OER is still not a routine part of Computer Science (CS) course development. Teaching experiences are in sharp contrast with the limited number of open related resources demonstrating them. To fill this gap, this project motivates and analyzes the evolution of the OER development and the emerging trends relevant to Computer Science education. The academic nature implies sharing knowledge and building upon ideas of others. OER provides a unique opportunity to expand the research traditions of building on the ideas of others into teaching practice. There are many observations demonstrated in [1] that educational research does not connect well with the open education practice. These observations are even more significant in the light of the following three facets of CS education which would benefit from CS OER production. Computer Science discipline. Computer Science is dynamic. It evolves and experiences transformation, continuously. Open teaching materials, covering emerging fields can help instructors and students unfamiliar with particular topics. CS graduates spend a significant part of their career in self-learning. Providing OER can help them stay current and grow along with their chosen profession. Computer Science career. Parallel demands come from employers. The workforce demands skills from college graduates that have to be acquired from informal learning experiences [2]. OER would enable them to learn new required skills or explore a new subject. Computer Science, Open Source Community (OSC). OER and Open Source Software (OSS) are similar in that both rely on sharing open assets and licenses that allow to use and modify.
