Though I was reasonably competent in the use of (earlier) versions of Camtasia Studio, I did take advantage of the certification courses accompanying the upgrade to Camtasia Studio 2021. This week, I completed two Camtasia 2021 certifications (1, 2).
I learned much by doing so and expect to continue to try some of the new features and experiment with SCORM production of Camtasia video quizzes to support of mathematics and robotics learning.
