    Digital repositories ten years on: what do scientific researchers think of them and how do they use them? :

    « Digital repositories have been with us for more than a decade, and despite the considerable media and conference attention they engender, we know very little about their use by academics. This paper sets out to address this by reporting on how well they are used, what they are used for, what researchers’ think of them, and where they thought they were going. Nearly 1,700 scientific researchers, mostly physical scientists, responded to an international survey of digital repositories, making it the largest survey of its kind. High deposit rates were found and mandates appear to be working, especially with younger researchers. Repositories have made significant inroads in terms of impact and use despite, in the case of institutional repositories, the very limited resources deployed. Subject repositories, like arXiv and PubMed Central, have certainly come of age but institutional repositories probably have not come of age yet although there are drivers in place which, in theory anyway, are moving them towards early adulthood. »

    A Preliminary Examination of the Cost Savings and Learning Impacts of Using Open Textbooks in Middle and High School Science Classes :

    « Proponents of open educational resources claim that significant cost savings are possible when open textbooks displace traditional textbooks in the classroom. Over a period of two years, we worked with 20 middle and high school science teachers (collectively teaching approximately 3,900 students) who adopted open textbooks to understand the process and determine the overall cost of such an adoption. The teachers deployed open textbooks in multiple ways. Some of these methods cost more than traditional textbooks; however, we did identify and implement a successful model of open textbook adoption that reduces costs by over 50% compared to the cost of adopting traditional textbooks. In addition, we examined the standardized test scores of students using the open textbooks and found no apparent differences in the results of students who used open textbooks compared with previous years when the same teachers’ students used traditional textbooks. However, given the limited sample of participating teachers, further investigation is needed. »

    The impact of open access initiative on knowledge sharing :

    « The main focus of this paper is to look at the role of the open access initiative (OAI) as a channel for knowledge sharing that could be used for the disseminate knowledge and research funding. For this purpose OAI was selected for analytical as role communication among the research. To assess if the articles found in the OAI contents knowledge sharing a method called contextual analysis was used. The result showed that OAI can aptly serve as a tool for disseminate knowledge and sharing ideas. By analysis is these material, OAI might be able to drive benefits directly or indirectly and eventually become beneficial took for scholars in their. »
