“知識共享”（CC）與開放教育資源（OER）之間的緊密關係
    一般而言，構成教育過程基礎的教學資源分為兩大類：非共享封閉類與開放共享類。比如，魯賓遜微積分教槽就是遵守“知識共享”許可協議（CC）的數字化教學資料，屬於開放教育資源（OER）的範疇。
    凡是不遵守“知識共享”許可協議的非數字化教學資料均不屬於“開放教育資源”的範疇。
    很顯然的是，凡不能數字化的紙質教學資料必定不能遵守“知識共享”許可協議（無共享可言），不是開放教育資源。
很榮幸的是，魯賓遜微積分教材遵守“知識共享”許可協議，理所當然，屬於開放教育資源（OER）範疇。
今天是向全國高校投放魯賓遜微積分教材“百日紀念”。數字化魯賓遜微積分教材是遠端開放教育的基礎，全國廣大高校師生均能獲益。
教學教材實現數字化是發展的大方向。
今日，第五輪投放已經完成，開放教育資源，全國永遠不嫌多。

Open educational resources (OER) are freely accessible, openly licensed text, media, and other digital assets that are useful for teaching, learning, and assessing as well as for research purposes. There is no universal usage of open file formats in OER.  
The term OER describes publicly accessible materials and resources for any user to use, re-mix, improve and redistribute under some licenses.[1]
The development and promotion of open educational resources is often motivated by a desire to provide an alternate or enhanced educational paradigm.[2]

Definition and scope
The idea of open educational resources (OER) has numerous working definitions.[3] The term was firstly coined at UNESCO's 2002 Forum on Open Courseware[4] and designates "teaching, learning and research materials in any medium, digital or otherwise, that reside in the public domain or have been released under an open license that permits no-cost access, use, adaptation and redistribution by others with no or limited restrictions. Open licensing is built within the existing framework of intellectual property rights as defined by relevant international conventions and respects the authorship of the work".[5] Often cited is the William and Flora Hewlett Foundation term which defines OER as:
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. Open educational resources include full courses, course materials, modules, textbooks, streaming videos, tests, software, and any other tools, materials, or techniques used to support access to knowledge.[6]
The Organization for Economic Co-operation and Development (OECD) defines OER as: "digitised materials offered freely and openly for educators, students, and self-learners to use and reuse for teaching, learning, and research. OER includes learning content, software tools to develop, use, and distribute content, and implementation resources such as open licences".[7] (This is the definition cited by Wikipedia's sister project, Wikiversity.) By way of comparison, the Commonwealth of Learning "has adopted the widest definition of Open Educational Resources (OER) as 'materials offered freely and openly to use and adapt for teaching, learning, development and research'".[8] The WikiEducator project suggests that OER refers "to educational resources (lesson plans, quizzes, syllabi, instructional modules, simulations, etc.) that are freely available for use, reuse, adaptation, and sharing'.[9][10]
The above definitions expose some of the tensions that exist with OER:
Nature of the resource: Several of the definitions above limit the definition of OER to digital resources, while others consider that any educational resource can be included in the definition.
Source of the resource: While some of the definitions require a resource to be produced with an explicit educational aim in mind, others broaden this to include any resource which may potentially be used for learning.
Level of openness: Most definitions require that a resource be placed in the public domain or under a fully open license. Others require only that free use to be granted for educational purposes, possibly excluding commercial uses.
These definitions also have common elements, namely they all:
cover use and reuse, repurposing, and modification of the resources;
include free use for educational purposes by teachers and learners
encompass all types of digital media.[11]
Given the diversity of users, creators and sponsors of open educational resources, it is not surprising to find a variety of use cases and requirements. For this reason, it may be as helpful to consider the differences between descriptions of open educational resources as it is to consider the descriptions themselves. One of several tensions in reaching a consensus description of OER (as found in the above definitions) is whether there should be explicit emphasis placed on specific technologies. For example, a video can be openly licensed and freely used without being a streaming video. A book can be openly licensed and freely used without being an electronic document. This technologically driven tension is deeply bound up with the discourse of open-source licensing. For more, see Licensing and Types of OER later in this article.
There is also a tension between entities which find value in quantifying usage of OER and those which see such metrics as themselves being irrelevant to free and open resources. Those requiring metrics associated with OER are often those with economic investment in the technologies needed to access or provide electronic OER, those with economic interests potentially threatened by OER,[12] or those requiring justification for the costs of implementing and maintaining the infrastructure or access to the freely available OER. While a semantic distinction can be made delineating the technologies used to access and host learning content from the content itself, these technologies are generally accepted as part of the collective of open educational resources.[13]
Since OER are intended to be available for a variety of educational purposes, most organizations using OER neither award degrees nor provide academic or administrative support to students seeking college credits towards a diploma from a degree granting accredited institution.[14][15] In open education, there is an emerging effort by some accredited institutions to offer free certifications, or achievement badges, to document and acknowledge the accomplishments of participants.
In order for educational resources to be OER, they must have an open license. Many educational resources made available on the Internet are geared to allowing online access to digitised educational content, but the materials themselves are restrictively licensed. Thus, they are not OER. Often, this is not intentional. Most educators are not familiar with copyright law in their own jurisdictions, never mind internationally. International law and national laws of nearly all nations, and certainly of those who have signed onto the World Intellectual Property Organization (WIPO), restrict all content under strict copyright (unless the copyright owner specifically releases it under an open license). The Creative Commons license is the most widely used licensing framework internationally used for OER.[16]
History
The term learning object was coined in 1994 by Wayne Hodgins and quickly gained currency among educators and instructional designers, popularizing the idea that digital materials can be designed to allow easy reuse in a wide range of teaching and learning situations.[17]
The OER movement originated from developments in open and distance learning (ODL) and in the wider context of a culture of open knowledge, open source, free sharing and peer collaboration, which emerged in the late 20th century.[17] OER and Free/Libre Open Source Software (FLOSS), for instance, have many aspects in common,[18][19] a connection first established in 1998 by David Wiley[20] who coined the term open content and introduced the concept by analogy with open source.[21] Richard Baraniuk made the same connection independently in 1999 with the founding of Connexions (now called OpenStax_CNX).[22]
The MIT OpenCourseWare project is credited for having sparked a global Open Educational Resources Movement after announcing in 2001 that it was going to put MIT's entire course catalog online and launching this project in 2002.[23] In a first manifestation of this movement, MIT entered a partnership with Utah State University, where assistant professor of instructional technology David Wiley set up a distributed peer support network for the OCW's content through voluntary, self-organizing communities of interest.[24]
The term "open educational resources" was first adopted at UNESCO's 2002 Forum on the Impact of Open Courseware for Higher Education in Developing Countries.[15]
In 2005 OECD's Centre for Educational Research and Innovation (CERI) launched a 20-month study to analyse and map the scale and scope of initiatives regarding "open educational resources" in terms of their purpose, content, and funding.[25] The report "Giving Knowledge for Free: The Emergence of Open Educational Resources",[26] published in May 2007, is the main output of the project, which involved a number of expert meetings in 2006.[27]
In September 2007, the Open Society Institute and the Shuttleworth Foundation convened a meeting in Cape Town to which thirty leading proponents of open education were invited to collaborate on the text of a manifesto. The Cape Town Open Education Declaration was released on 22 January 2008,[28] urging governments and publishers to make publicly funded educational materials available at no charge via the internet.[29]
The global movement for OER culminated at the 1st World OER Congress convened in Paris on 20–22 June 2012 by UNESCO, COL and other partners. The resulting Paris OER Declaration (2012) reaffirmed the shared commitment of international organizations, governments, and institutions to promoting the open licensing and free sharing of publicly funded content, the development of national policies and strategies on OER, capacity-building, and open research.[16] In 2018, the 2nd World OER Congress in Ljubljana, Slovenia, was co-organized by UNESCO and the Government of Slovenia. The 500 experts and national delegates from 111 countries adopted the Ljubljana OER Action Plan.[30] It recommends 41 actions to mainstream open-licensed resources to achieve the 2030 Sustainable Development Goal 4 on “quality and lifelong education".[31]
An historical antecedent to consider is the pedagogy of artist Joseph Beuys and the founding of the Free International University for Creativity and Interdisciplinary Research in 1973. After co-creating with his students, in 1967, the German Student Party, Beuys was dismissed from his teaching post in 1972 at the Staatliche Kunstakademie Düsseldorf. The institution did not approve of the fact that he permitted 50 students who had been rejected from admission to study with him. The Free University became increasingly involved in political and radical actions calling for a revitalization and restructuring of educational systems.[32][33]
Licensing and types[edit]

Play media

Turning a Resource into an Open Educational Resource
Open educational resources often involve issues relating to intellectual property rights. Traditional educational materials, such as textbooks, are protected under conventional copyright terms. However, alternative and more flexible licensing options have become available as a result of the work of Creative Commons, a non-profit organization that provides ready-made licensing agreements that are less restrictive than the "all rights reserved" terms of standard international copyright. These new options have become a "critical infrastructure service for the OER movement."[34] Another license, typically used by developers of OER software, is the GNU General Public License from the free and open-source software (FOSS) community. Open licensing allows uses of the materials that would not be easily permitted under copyright alone.[35]
Types of open educational resources include: full courses, course materials, modules, learning objects, open textbooks, openly licensed (often streamed) videos, tests, software, and other tools, materials, or techniques used to support access to knowledge. OER may be freely and openly available static resources, dynamic resources which change over time in the course of having knowledge seekers interacting with and updating them (such as this Wikipedia article), or a course or module with a combination of these resources.
OER policy[edit]
Main article: Open educational resources policy
Open educational resources policies are principles or tenets adopted by governing bodies in support of the use of open content and practices in educational institutions. Many of these policies require publicly funded resources be openly licensed. Such policies are emerging increasingly at the country, state/province and more local level.[36]
Creative Commons hosts an open educational resources policy registry lists 95 current and proposed open education policies from around the world.[37]
Creative Commons and multiple other open organizations launched the Open Policy Network to foster the creation, adoption and implementation of open policies and practices that advance the public good by supporting open policy advocates, organizations and policy makers, connecting open policy opportunities with assistance, and sharing open policy information.[38]
Costs[edit]
One of the most frequently cited benefits of OER is their potential to reduce costs.[39][40][41][42] While OER seem well placed to bring down total expenditures, they are not cost-free. New OER can be assembled or simply reused or repurposed from existing open resources. This is a primary strength of OER and, as such, can produce major cost savings. OER need not be created from scratch. On the other hand, there are some costs in the assembly and adaptation process. And some OER must be created and produced originally at some time. While OER must be hosted and disseminated, and some require funding, OER development can take different routes, such as creation, adoption, adaptation and curation.[16]
Each of these models provides different cost structure and degree of cost-efficiency. Upfront costs in developing the OER infrastructure can be expensive, such as building the OER infrastructure. Butcher and Hoosen[43] noted that “a key argument put forward by those who have written about the potential benefits of OER relates to its potential for saving cost or, at least, creating significant economic efficiencies. However, to date there has been limited presentation of concrete data to back up this assertion, which reduces the effectiveness of such arguments and opens the OER movement to justified academic criticism.”[16]
Institutional support[edit]
A large part of the early work on open educational resources was funded by universities and foundations such as the William and Flora Hewlett Foundation,[23] which was the main financial supporter of open educational resources in the early years and has spent more than $110 million in the 2002 to 2010 period, of which more than $14 million went to MIT.[14] The Shuttleworth Foundation, which focuses on projects concerning collaborative content creation, has contributed as well. With the British government contributing £5.7m,[44] institutional support has also been provided by the UK funding bodies JISC[45] and HEFCE.[46]
UNESCO is taking a leading role in "making countries aware of the potential of OER."[47] The organisation has instigated debate on how to apply OERs in practice and chaired vivid discussions on this matter through its International Institute of Educational Planning (IIEP).[citation needed] Believing that OERs can widen access to quality education, particularly when shared by many countries and higher education institutions, UNESCO also champions OERs as a means of promoting access, equity and quality in the spirit of the Universal Declaration of Human Rights.[48] In 2012 the Paris OER Declaration[49] was approved during the 2012 OER World Congress held at UNESCO's headquarters in Paris.
Initiatives[edit]
A parallel initiative, OpenStax CNX (formerly Connexions), came out of Rice University starting in 1999. In the beginning, the Connexions project focused on creating an open repository of user-generated content. In contrast to the OCW projects, content licenses are required to be open under a Creative Commons Attribution International 4.0 (CC BY) license. The hallmark of Connexions is the use of a custom XML format CNXML, designed to aid and enable mixing and reuse of the content.
In 2012, OpenStax was created from the basis of the Connexions project. In contrast to user-generated content libraries, OpenStax hires subject matter experts to create college-level textbooks that are peer-reviewed, openly licensed, and available online for free.[50] Like the content in OpenStax CNX, OpenStax books are available under Creative Commons CC BY licenses that allow users to reuse, remix, and redistribute content as long as they provide attribution. OpenStax's stated mission is to create professional grade textbooks for the highest-enrollment undergraduate college courses that are the same quality as traditional textbooks, but are adaptable and available free to students.[50]
Other initiatives derived from MIT OpenCourseWare are China Open Resources for Education and OpenCourseWare in Japan. The OpenCourseWare Consortium, founded in 2005 to extend the reach and impact of open course materials and foster new open course materials, counted more than 200 member institutions from around the world in 2009.[51]
OER Africa, an initiative established by the South African Institute for Distance Education (Saide) to play a leading role in driving the development and use of OER across all education sectors on the African continent.[52] The OER4Schools project focusses on the use of Open Educational Resources in teacher education in sub-Saharan Africa.
Wikiwijs (the Netherlands), was a program intended to promote the use of open educational resources (OER) in the Dutch education sector;[53]
The Open educational resources programme (phases one[54] and two[55]) (United Kingdom), funded by HEFCE, the UK Higher Education Academy and Jisc, which has supported pilot projects and activities around the open release of learning resources, for free use and repurposing worldwide.
In 2003, the ownership of Wikipedia and Wiktionary projects was transferred to the Wikimedia Foundation, a non-profit charitable organization whose goal is to collecting and developing free educational content and to disseminate it effectively and globally. Wikipedia ranks in the top-ten most visited websites worldwide since 2007.
OER Commons was spearheaded in 2007 by ISKME, a nonprofit education research institute dedicated to innovation in open education content and practices, as a way to aggregate, share, and promote open educational resources to educators, administrators, parents, and students. OER Commons also provides educators tools to align OER to the Common Core State Standards; to evaluate the quality of OER to OER Rubrics; and to contribute and share OERs with other teachers and learners worldwide. To further promote the sharing of these resources among educators, in 2008 ISKME launched the OER Commons Teacher Training Initiative, which focuses on advancing open educational practices and on building opportunities for systemic change in teaching and learning.
One of the first OER resources for K-12 education is Curriki. A nonprofit organization, Curriki provides an Internet site for open source curriculum (OSC) development, to provide universal access to free curricula and instructional materials for students up to the age of 18 (K-12). By applying the open source process to education, Curriki empowers educational professionals to become an active community in the creation of good curricula. Kim Jones serves as Curriki's Executive Director.[citation needed]
In August 2006 WikiEducator was launched to provide a venue for planning education projects built on OER, creating and promoting open education resources (OERs), and networking towards funding proposals.[56] Its Wikieducator's Learning4Content project builds skills in the use of MediaWiki and related free software technologies for mass collaboration in the authoring of free content and claims to be the world's largest wiki training project for education. By 30 June 2009 the project facilitated 86 workshops training 3,001 educators from 113 different countries.[57]
Between 2006 and 2007, as a Transversal Action under the European eLearning Programme, the Open e-Learning Content Observatory Services (OLCOS) project carries out a set of activities that aim at fostering the creation, sharing and re-use of Open Educational Resources (OER) in Europe and beyond. The main result of OLCOS was a Roadmap,[58] in order to provide decision makers with an overview of current and likely future developments in OER and recommendations on how various challenges in OER could be addressed.[citation needed]
Peer production has also been utilized in producing collaborative open education resources (OERs). Writing Commons, an international open textbook spearheaded by Joe Moxley at the University of South Florida, has evolved from a print textbook into a crowd-sourced resource for college writers around the world.[59] Massive open online course (MOOC) platforms have also generated interest in building online eBooks. The Cultivating Change Community (CCMOOC) at the University of Minnesota is one such project founded entirely on a grassroots model to generate content.[60] In 10 weeks, 150 authors contributed more than 50 chapters to the CCMOOC eBook and companion site.[61]
In 2011-12, academicians from the University of Mumbai, India created an OER Portal with free resources on Micro Economics, Macro Economics, and Soft Skills – available for global learners.[62]
Another project is the Free Education Initiative from the Saylor Foundation, which is currently more than 80% of the way towards its initial goal of providing 241 college-level courses across 13 subject areas.[63] The Saylor Foundation makes use of university and college faculty members and subject experts to assist in this process, as well as to provide peer review of each course to ensure its quality. The foundation also supports the creation of new openly licensed materials where they are not already available as well as through its Open Textbook Challenge.[64]
In 2010 the University of Birmingham and the London School of Economics worked together on the HEA and JISC funded DELILA project, the main aim of the project was to release a small sample of open educational resources to support embedding digital and information literacy education into institutional teacher training courses accredited by the HEA including PGCerts and other CPD courses.[65] One of the main barriers that the project found to sharing resources in information literacy was copyright that belonged to commercial database providers[66]
In 2006, the African Virtual University (AVU) released 73 modules of its Teacher Education Programs as open education resources to make the courses freely available for all. In 2010, the AVU developed the OER Repository which has contributed to increase the number of Africans that use, contextualize, share and disseminate the existing as well as future academic content. The online portal serves as a platform where the 219 modules of Mathematics, Physics, Chemistry, Biology, ICT in education, and teacher education professional courses are published. The modules are available in three different languages – English, French, and Portuguese, making the AVU the leading African institution in providing and using open education resources[67]
In August 2013, Tidewater Community College become the first college in the U.S. to create an Associate of Science degree based entirely on openly licensed content – the "Z-Degree". The combined efforts of a 13-member faculty team, college staff and administration culminated when students enrolled in the first "z-courses" which are based solely on OER. The goals of this initiative were twofold: 1) to improve student success, and 2) to increase instructor effectiveness. Courses were stripped down to the Learning Outcomes and rebuilt using openly licensed content, reviewed and selected by the faculty developer based on its ability to facilitate student achievement of the objectives. The 21 z-courses that make up an associate of science degree in business administration were launched simultaneously across four campus locations. TCC is the 11th largest public two-year college in the nation, enrolling nearly 47,000 students annually.[68]
During this same time period from 2013-2014, Northern Virginia Community College (NOVA) also created 2 zero cost OER degree pathways: one an associate's degree in General Studies, the other an associate's degree in Social Science. One of the largest community colleges in the nation, NOVA serves around 75,000 students across six campuses. The Extended Learning Institute (ELI) is the centralized online learning hub for the entire college. Dr. Wm. Preston Davis, Director of Instructional services at ELI, led this OER initiative called the OER-Based General Education Project. Davis led the ELI team of faculty, instructional designers and librarians on the project to create what NOVA calls "digital open" courses. During the planning phase, the team was careful to select core, high-enrollment courses that could impact as many students as possible, regardless of specific course of study. At the same time, the team looked beyond individual courses to create depth and quality around full pathways for students to earn an entire degree. Currently, 20% of students at NOVA have taken an OER course and enrollment in these courses is rising. From Fall 2013 to Fall 2016, more than 15,000 students have enrolled in NOVA OER courses yielding textbook cost savings of over 2 million dollars over the three-year period[69]. Currently, NOVA is working to add a third OER degree pathway in Liberal Arts.
Nordic OER is a Nordic network to promote open education and collaboration amongst stakeholders in all educational sectors. The network has members from all Nordic countries and facilitates discourse and dialogue on open education but also participates in projects and development programs. The network is supported by the Nordic OER project co-funded by Nordplus.
In Norway the Norwegian Digital Learning Arena (NDLA) is a joint county enterprise offering open digital learning resources for upper secondary education. In addition to being a compilation of open educational resources, NDLA provides a range of other online tools for sharing and cooperation. At project startup in 2006, increased volume and diversity were seen as significant conditions for the introduction of free learning material in upper secondary education.[70] The incentive was an amendment imposing the counties to provide free educational material, in print as well as digital, including digital hardware.[71]
In Sweden there is a growing interest in open publication and the sharing of educational resources but the pace of development is still slow. There are many questions to be dealt with in this area; for universities, academic management and teaching staff. Teachers in all educational sectors require support and guidance to be able to use OER pedagogically and with quality in focus. To realize the full potential of OER for students' learning it is not enough to make patchwork use of OER – resources have to be put into context. Valuable teacher time should be used for contextual work and not simply for the creation of content. The aim of the project OER for learning OERSweden is to stimulate an open discussion about collaboration in infrastructural questions regarding open online knowledge sharing. A network of ten universities led by Karlstad University will arrange a series of open webinars during the project period focusing on the use and production of open educational resources. A virtual platform for Swedish OER initiatives and resources will also be developed. The project intends to focus in particular on how OER affects teacher trainers and decision makers. The objectives of the project are: To increase the level of national collaboration between universities and educational organisations in the use and production of OER, To find effective online methods to support teachers and students, in terms of quality, technology and retrievability of OER, To raise awareness for the potential of webinars as a tool for open online learning, To increase the level of collaboration between universities' support functions and foster national resource sharing, with a base in modern library and educational technology units, and To contribute to the creation of a national university structure for tagging, distribution and storage of OER.
Founded in 2007, the CK-12 Foundation is a California-based non-profit organization whose stated mission is to reduce the cost of, and increase access to, K-12 education in the United States and worldwide.[72] CK-12 provides free and fully customizable K-12 open educational resources aligned to state curriculum standards and tailored to meet student and teacher needs. The foundation's tools are used by 38,000 schools in the US, and additional international schools.[72]
LATIn Project brings a Collaborative Open Textbook Initiative for Higher Education tailored specifically for Latin America. This initiative encourages and supports local professors and authors to contribute with individual sections or chapters that could be assembled into customized books by the whole community. The created books are freely available to the students in an electronic format or could be legally printed at low cost because there is no license or fees to be paid for their distribution, since all they are released as OER with a Creative Commons CC-BY-SA license. This solution also contributes to the creation of customized textbooks where each professor could select the sections appropriate for their courses or could freely adapt existing sections to their needs. Also, the local professors will be the sink and source of the knowledge, contextualized to the Latin American Higher Education system.
In 2014, the William and Flora Hewlett Foundation started funding the establishment of an OER World Map that documents OER initiatives around the world. Since 2015, the hbz and graphthinking GmbH develop the service with funding by the Hewlett Foundation at https://oerworldmap.org. The first version of the website was launched in March 2015[73] and the website is continuously developing. The OER World Map invites people to enter a personal profile as well to add their organization, OER project or service to the database.
In March 2015, Eliademy.com launched the crowdsourcing of OER courses under CC licence. The platform expects to collect 5000 courses during the first year that can be reused by teachers worldwide.[74]
In 2015, the University of Idaho Doceo Center launched open course content for K-12 schools, with the purpose of improving awareness of OER among K-12 educators.[75] This was shortly followed by an Open Textbook Crash Course,[76] which provides K-12 educators with basic knowledge about copyright, open licensing, and attribution. Results of these projects have been used to inform research into how to support K-12 educator OER adoption literacies and the diffusion of open practices.[77]
In 2015, the MGH Institute of Health Professions, with help from an Institute of Museum and Library Services Grant (#SP-02-14-0), launched the Open Access Course Reserves. With the idea that many college level courses rely on more than a single textbook to deliver information to students, the OACR is inspired by library courses reserves in that it supplies entire reading lists for typical courses. Faculty can find, create, and share reading lists of open access materials.
Today, OER initiatives across the United States rely on individual college and university librarians to curate resources into lists on library content management systems called LibGuides. Find OER repositories by discipline through the use of an individualized LibGuide such as the one found here from Indian River State College, [1].
International programs[edit]
High hopes have been voiced for OERs to alleviate the digital divide between the global North and the global South, and to make a contribution to the development of less advanced economies.[78]
Europe – Learning Resource Exchange for schools (LRE) is a service launched by European Schoolnet in 2004 enabling educators to find multilingual open educational resources from many different countries and providers. Currently, more than 200,000 learning resources are searchable in one portal based on language, subject, resource type and age range.
India – National Council Of Educational Research and Training digitized all its textbooks from 1st standard to 12th standard. The textbooks are available online for free. Central Institute of Educational Technology, a constituent Unit of NCERT, digitized more than thousand audio and video programmes. All the educational AV material developed by CIET is presently available at Sakshat Portal an initiative of Ministry of Human Resources and Development. In addition, NROER (National Repository for Open Educational Resources) houses variety of e-content.
US – Washington State's Open Course Library Project is a collection of expertly developed educational materials – including textbooks, syllabi, course activities, readings, and assessments – for 81 high-enrolling college courses. All course have now been released and are providing faculty with a high-quality option that will cost students no more than $30 per course. However, a study found that very few classes were actually using these materials (http://www.nacs.org/Portals/NACS/Uploaded_Documents/PDF/Research/OCLresults2014.pdf).
Dominica – The Free Curricula Centre at New World University expands the utility of existing OER textbooks by creating and curating supplemental videos to accompany them, and by converting them to the EPUB format for better display on smartphones and tablets.[79]
Bangladesh is the first country to dig
