• Compare L1 and L2 acquisition/learning, including an explanation of how the L1 influences L2 acquisition/learning.
• Describe five stages of L2 acquisition, including at least three linguistic characteristics of learners at each stage and an academic support a teacher can provide for each stage.
• Describe two personal/individual factors affecting L2 acquisition/learning and how knowledge of these factors can inform teaching practice and responsiveness to students.
• Discuss two myths or misconceptions of L2 acquisition/learning and clarifications based on research.
• Explain sociolinguistics and how the sociocultural context influences language learning and use. Include examples of how to use students' sociocultural and linguistic resources to enhance their learning.
