I regularly use Common Craft videos as an example of creating effective video lessons without spending a lot of money on special equipment or software. In fact, I did it in a webinar I presented yesterday. The video I used as an example was Research Papers Explained by Common Craft.
Research papers explained by Common Craft do an excellent job of explaining to students why the research papers they write in school are good practice for life in a work environment. The video does this by following the example of trying to convince your boss to give you a raise.
Common Craft videos can be viewed on their website. To use it in your school, you need a Common Craft membership.
Disclosure: I have a long-term, in-child relationship with Common Craft.
