This study examines the impact of Technological Pedagogical Content Knowledge in-Action model based in-house professional development workshops on teachers’ practices of technology integration at a Saudi university. The study uses questionnaires to gather feedback on the participants’ pre and post training workshops, coupled by semi-structured interviews to highlight factors that determined the outcome of the training workshops. The findings show that despite the participants being qualified in pedagogy, they were unable to successfully use their expertise to beneficially incorporate technology in their teaching. The failure partly occurred due to apparent misunderstanding of confusing the knowledge of an application with the pedagogical skills of using the application, and partly due to the lack of concrete guidance by the administration on what and how to integrate technology in regular teaching. The study recommends to structure training workshops incorporating pedagogical handling of technology alongside technical training on how to use an application. The study also suggests that an institutional policy regarding the use of technology is inevitable to make such ventures successful. Such a policy needs to be devised and incorporated in regular syllabus, and should be clearly addressed in all training workshops on professional development.
