Despite the significance of incorporating technology into geometry instruction, many teachers still find it difficult to teach geometry using technology. This study employed a techno- pedagogical content knowledge (TPACK) survey of 70 pre-service mathematics teachers (29 males, 41 females) from a public university. The goal was to determine which domains, if any, were open for development so that a course could be designed to meet these needs. The data was analysed thematically according to the TPACK sub-domains. The results showed that the pre-service teachers were confident in the areas of pedagogy knowledge, content knowledge, and pedagogical content knowledge (90% confidence) and open to improvement in the areas of technology, technological content, and technological pedagogy knowledge (70% confidence). As a result, we suggest creating a 14-week course to increase pre-service mathematics teachers' TPACK of these components in the hopes of bridging the knowledge gap identified in this study.
