FUZZY NUMBERS AS AN ASSESSMENT TOOL IN THE APOS/ACE INSTRUCTIONAL TREATMENT FOR MATHEMATICS

Abstract. Voskoglou M. Gr. Fuzzy Numbers as an Assessment Tool in the APOS/ACE Instructional Treatment of Mathematics. In the article a combination is used of of the Triangular Fuzzy Numbers (TFNs) and the Center of Gravity (COG) defuzzification technique to assess university student skills for learning mathematics with the APOS/ACE instructional treatment.
​Key words: APOS/ACE instructional treatment of mathematics, triangular fuzzy numbers (TFNs), center of gravity (COG) defuzzification technique.
