The Educational Technology Certificate (ETC.) courses at Michigan State University are a set of three courses that can be taken as a standalone qualification or as the first three courses in the Master's of Educational Technology degree. Together, the courses emphasize the development of technology skills and advanced mindsets for technology integration in the classroom. In this article, we provide examples of our approach to the teaching of technology skills and mindsets in ways that are adaptable across four distinct modes of instruction (online, hybrid, overseas and face-to-face). We also present student feedback and survey data that inform a critical evaluation of the program's effectiveness. Findings suggest that the certificate courses help students to gain technological skills, to become more confident users of technology and more likely to help colleagues with tech-related questions. Interestingly, respondents also reported feeling like better teachers, in general, after taking these courses.
