This presentation will share best practices and highlight the significance of formative assessment with constructive feedback in foreign language learning.

By incorporating targeted, specific, timely, balanced, differentiated, and supportive feedback, this approach tailors teaching strategies to meet individual learner needs. The presenters will also explore practical strategies for implementing formative assessment and designing learning activities that foster cooperative and collaborative learning, ultimately promoting student engagement and self-regulation in language learning.
