Vietnam's Ministry of Education and Training has introduced educational reforms that require Vietnamese teachers to acquire new understanding and skills using information communication technology (ICT) to support teaching. However, there was little literature to guide Vietnamese teachers on how to achieve these goals. The research goals were to implement a theoretical pedagogic model to integrate constructivist and sociocultural learning principles with ICT for teaching physics, and test whether the model would increase interaction within the learning environment, and improve students' physics test results and critical thinking skills. This research was conducted in a Vietnamese context. Data collection methods included student interviews, physics tests and critical thinking skills tests. The result of this study showed that the use of ICT informed by the model can enhance interaction in the learning environment, and students' physics test performance and critical thinking skills. This study can provide guidance for the current strategy of implementing ICT into education. At a global level there is little searchable research on the integration of ICT in teaching physics in Vietnam. The current study contributes to the literature by providing insights into the use of ICT in teaching physics in the Vietnamese context.
