A 77-year-old professor talks about how he incorporates open source teaching methods. The open source technologies of today are more respectful; they allow students to do their work in the time and space that best fits their life and their circumstances???which for many includes a job. Socially, they are more collaborative and participatory. Technically, they allow efficient access to material that is more inclusive, comprehensive, engaging and up-to-date. Thankfully, I did change my focus… and much more.
