The student's research design is clearly described and explained, as they correctly identify it as independent measures and explain how it was applied in their study. The sampling technique used, opportunity sampling, is also correctly identified and explained. However, it would be beneficial for the student to provide a more convincing justification for why they chose this sampling method. The student describes relevant characteristics of the research participants, such as their language, age, gender, and ethnicity. The choice of participants is explained, with the exclusion of teachers being justified. However, the student could have also explained why the students' age or English proficiency was relevant. The controlled variables and their reasons for control, as well as all materials used, are stated, but no further explanation is provided.
