Assessment doesn't have to be threatening and arduous but can be an effective tool in promoting language learning and in guiding students to improve their communication skills. In this session, I will talk about the key concept of positive impact by design and the current trends in Learning Oriented Assessment (LOA) that seek to integrate learning and assessment more effectively. I will discuss how formative and summative functions of assessments can work holistically to build more effective learning ecosystems in the Vietnamese context. I will conclude my talk with some ideas about how LOA can help improve educational standards in the post-Covid era, especially with the support of EdTech. Teachers have a key role to play in this; they will need to engage with these issues in their own schools and communities, and to be prepared for this challenging but exciting period ahead.
