Homework for ESL learners can indeed be beneficial.

a. It increases speaking time. Since adults often have busy schedules, assigning homework allows you to practice and reinforce language skills outside of class. Completing exercises at home enables you to focus more on speaking during class periods. 

b. It provides time for review and reinforcement. Homework provides an opportunity for you to review and consolidate the material covered in class. It reinforces vocabulary, grammar, and language concepts, helping you retain what you have learned. 

c. It creates a sense of empowerment. By taking responsibility for your own learning process, you may feel empowered. Homework encourages self-directed study and will motivate you to engage actively with the language.
