The student clearly describes and explains the research design, detailing an independent measures design where participants were randomly assigned to groups, effectively minimizing biases and individual differences. The sampling technique of convenience sampling is well-articulated, with participants selected from a Year 11 Mathematics class to ensure minimal disruption. The student provides relevant characteristics of the research participants, noting their age, gender distribution, and English proficiency, which supports clear communication during the experiment. While the choice of participants is generally well justified, the student could improve by further explaining the necessity of English fluency for the validity of the study. Additionally, the student effectively identifies and describes controlled variables and explains the reasoning behind controlling specific variables, ensuring a consistent and ethical methodology. Finally, all materials used in the methodology are listed and their choices are clearly justified, contributing to the overall clarity and rigor of the research.
