Each well-established school should go through a regular, periodic curriculum review cycle. We are currently in the process of revising the Standards, Can Do Statements, and Learning Targets for our Mandarin as a Foreign Language track. They are a vast set of statements, inspired by the ACTFL Standards and Proficiency Guidelines.
During a Curriculum Work Session, all our Mandarin teachers engaged in a thorough revision of all our guiding statements, in an effort to ensure that they are still accurate, that they match within the different categories, and that they promote authentic communication.
Next steps would be to make the necessary changes and adjustments, based on the team's findings and on latest research and best practices in language acquisition. The journey to improvement leads sometimes up a sinuous pathway, and it never really ends!
