Final answer:
RAPID uses two tasks, Grasp Checks and Practice Problems, to assess academic language.
Step-by-step explanation:
The two tasks that RAPID uses to assess academic language are Grasp Checks and Practice Problems. Grasp Checks are formative assessments that review comprehension of concepts and skills through reading and interactive features. Practice Problems challenge students to apply concepts and skills they have learned in Worked Examples to solve a problem. These tasks provide students with opportunities to practice and apply their understanding of academic language.
