Assessment is one of the critical tasks performed by teachers worldwide every day. Although grading students may look simple and easy, teachers face some dilemmas when choosing the assessment criteria and method. Should the assessment be summative or formative? Should the grading system be objective or subjective? How to give feedback? Rubrics meet all those questions providing teachers and students with clear and instructive authentic assessment and formative feedback.
BBC is a useful website for both teachers and students. Teachers can find tons of materials for their English classes, and students can find resources for self-study. Take some time to go through the pages searching for ideas. In particular, I like the Grammar Challenges. Let me know your opinion about BBC Learning English.
