On the use of key words and visual representations in solving probability problems
PresenterSweet Rose Leonares (Philippines)
This study aimed to demonstrate the use of keywords and visual representations in solving probability problems. The research design was descriptive qualitative using the phenomenographic approach, involving fifteen third year undergraduate Mathematics education majors enrolled in Elementary Probability Theory. A 7-item pretest and a parallel posttest consisting of typical probability problems were administered and interviews using the Newman Error Analysis prompts were conducted after each test. Instruction focused on the use of keywords and visual representations. Pretest results showed students committing low-level (comprehension) errors. Higher-level errors were observed in the posttest with more appropriate and predominant use of keywords and visual representations. The results of the study look promising and using keywords and visual representations as a pedagogical approach in teaching probability is recommended.
