The primary objective of this course is the development of language teachers' assessment literacy, which includes knowledge of key assessment principles and skill in creating or adopting assessment tools and procedures for the language classroom. Participants in this course will develop their knowledge and skills related to assessing all skill areas in the language classroom, including productive skills (writing, speaking), receptive skills (reading, listening), and assessing grammar and vocabulary. Grading and student evaluation will also be important topics of consideration and exploration in this course. Designed specifically for in-service (and pre-service) language teachers, the course combines theory with practice by covering essential principles of effective classroom assessment and the development of effective assessment tools for classroom use. Participants completing this course will become more assessment literate and better able to evaluate student performance in their classrooms fairly and effectively.
