Editing Blended learning (section)

==History==
While the first [[distance learning]] programs were introduced in the 1840s, technology-facilitated learning did not exist before the 1970s.<ref name=":2" /> Technology-based training emerged as an alternative to instructor-led training in the 1960s on mainframes and mini-computers. The major advantage that blended learning offers is scale, whereas one instructor can only teach so many people.<ref>{{cite book | chapter-url=http://media.wiley.com/product_data/excerpt/67/07879729/0787972967.pdf | title=The Blended Learning Book: Best Practices, Proven Methodologies, and Lessons Learned | publisher=Wiley | author=Bersin, Josh | year=2004 | isbn=978-0-7879-7296-7 | chapter=How Did We Get Here?

PLATO in particular had a long history of innovations and offered coursework from elementary to the college level.<ref>{{cite web |title=Plato Rising |url=http://www.atarimagazines.com/v3n3/platorising.html |access-date=October 24, 2013 |publisher=Atarimagazines.com}}</ref> [[Mainframe computer|Mainframe]]-based training had a number of interface limitations that gave way to satellite-based live video in the 1970s. The advantage here was serving people who were not as computer literate. The major challenge was the expense required to make this work.

Satellite-based live video and [[CD-ROM]] based education delivery systems became popular as a way to solve issues with scale.<ref>{{Cite book |last=Fong |first=Joseph |url=https://books.google.com/books?id=Cy0YwEofp2oC&dq=blended+learning+cd+rom&pg=PA192 |title=Hybrid Learning and Education: First International Conference, ICHL 2008 Hong Kong, China, August 13–15, 2008 Proceedings |date=July 30, 2008 |publisher=Springer Science & Business Media |isbn=978-3-540-85169-1 |pages=192–193 |language=en}}</ref> Becoming a popular method in the late 1980s and early 1990s,<ref name=":2">{{Cite book |last1=Ahuja |first1=Neelu Jyothi |url=https://books.google.com/books?id=bPPSEAAAQBAJ&dq=blended+learning+cd+rom&pg=PA252 |title=Sustainable Blended Learning in STEM Education for Students with Additional Needs |last2=Kumar |first2=Adarsh |last3=Nayyar |first3=Anand |date=August 24, 2023 |publisher=Springer Nature |isbn=978-981-99-3497-3 |pages=252 |language=en}}</ref> CD-ROMs emerged as a dominant form of providing technology-based learning as bandwidth through 56k modems wasn't able to support very high quality sound and video. The limitation to CD-ROMs was tracking completion of coursework, so [[learning management system]]s emerged as a way to facilitate progress tracking. The aviation industry used this heavily to track how well one did on courses, how much time was spent, and where someone left off. AICC, [[Aviation Industry Computer-Based Training Committee]], was formed in 1988 and companies such as Boeing used CD-ROMs to provide training for personnel.

Modern blended learning is delivered online, although CD-ROMs could feasibly still be used if a learning management system meets an institution's standards. Some examples of channels through which online blending learning can be delivered include webcasting (synchronous and asynchronous) and online video (live and recorded).<ref>{{Cite journal |last1=Smith |first1=David P. |last2=Francis |first2=Nigel J. |date=April 29, 2022 |editor-last=Mello |editor-first=Luciane V |editor2-last=Watson |editor2-first=Helen |title=Engagement with video content in the blended classroom |url=https://portlandpress.com/essaysbiochem/article/66/1/5/231051/Engagement-with-video-content-in-the-blended |journal=Essays in Biochemistry |language=en |volume=66 |issue=1 |pages=5–10 |doi=10.1042/EBC20210055 |issn=0071-1365 |pmc=9096563 |pmid=35293999}}</ref>

Solutions such as [[Khan Academy]] have been used in classrooms to serve as platforms for blended learning.<ref>{{cite web |author=Coach resources |url=https://www.khanacademy.org/coach-res/case-studies |title=in the real world &#124; Coach resources |publisher=Khan Academy |date=October 11, 2012 |access-date=October 24, 2013 |archive-url=https://web.archive.org/web/20131023172305/http://www.khanacademy.org/coach-res/case-studies |archive-date=October 23, 2013 |url-status=dead }}</ref>
