This study sought to narrate the experiences of a digital novice South African rural teacher, using technological pedagogical reasoning (TPR). The ubiquity and pervasiveness of digital technology is creating a need for teachers to develop TPR to remain relevant in this ever-changing global teaching community. TPR is developed in the real context of a teacher's practice; hence, teachers need to have the experiences of learning to teach with technology in their actual classes. In this study, one South African rural teacher found computer simulations (CS) to be curricular materials with the potential to transform how physical sciences can be taught in South African rural schools. Their affordances are many, depending on how they can be manipulated by the user to add value to their pursuits. In addition, they have pragmatic value to the practice of South African teachers. The benefits of using CS were informed by using the technological pedagogical reasoning (TPR) framework. These affordances were relational, uncovered through an active interaction with the technology and the learners. The use of technology in teaching does not come with a pedagogical manual; hence, their use by the individual teachers is idiosyncratic. Hence, this creates a need for more research in the use of specific technology while teaching in rural schools to develop a more nuanced understanding of TPR.
