Summarizing the History of LDT

Instructional Films

1908

1908 could be thought of as the "first falling domino," and marked the start of a movement that welcomed visual aides, such as instructional films, to be commonplace among education. It serves as a defining point in history for the long line of visual and technological advancements that lie ahead. Reiser, R.A. (2001) A history of instructional design and technology: part I: A history of instructional media. Educational Technology Research & Development, 49(1), 53-64.

Instructional Television

1950

While this advancement ebbed and flowed over the coming years (due to lack of funding and difficulty for the time period) this still marks a critical era that will be expanded upon in the coming years, and eventually blossom into what we see today.

Instruction via Internet and Wikis

1998

After the creation of the world wide web in 1989, "Wikis" lead to a new era of information sharing in that anyone could contribute to the conversation through one shared platform. Weller, M. (2018).

Instructional Blogs

2003

While blogs originated as a type of online diary, they quickly transformed into a method of information sharing and online learning. One can quickly access a blog for any type of niche subject, and receive step by step instruction from experienced creatives all around the world. Weller, M. (2018). Twenty Years of EdTech. In R. E.

Instructional YouTube Videos

2005

YouTube helped further contribute to video's role as an educational tool, and this time, anyone can contribute. Like blogs, the sky is the limit for niche topics one could educate their viewers on, making it such that anyone can learn almost anything if they have access to the internet.

Instruction via Social Media

2009

The Age of "Connectivism." Social media made it faster than ever before to share content on numerous platforms, all at the same time. Not only can social media be it's own platform of education, but it can also serve as a means to share links that then lead to instructional videos and blogs. Weller, M. (2018).
