This course will explore the guiding principles for world language education that inform the practices of teachers in the U.S. and that align with ACTFL standards. ACTFL is the national organization of world language teachers in the U.S., and this course will be taught by the 2020 ACTFL president. The principles we will focus on are comprehensible input for maximum target language use, using authentic texts, and teaching grammar in a contextualized way. For each principle, we will compare it with the participants’ experiences as language learners and reflect on similarities and differences. We will apply each principle by practicing strategies to utilize in the classroom. We will utilize free resources available on the ACTFL website as the recommended readings. The site is https://www.actfl.org/educator-resources/guiding-principles-for-language-learning. By the end of the course, participants will be able to integrate these principles in their own language learning practices.
