Achievement Goals Analysis in the Learning of Calculus Based on Fuzzy Number Conjoint Method

Abstract

The conjoint method, which is based on fuzzy sets of numbers, is widely used to describe linguistic values for human preference in an uncertain environment. However, the fuzzy sets used to describe the membership function of linguistic value do not realistically represent the physical world, so the conjoint method can fill the gap and produce more meaningful results. The fuzzy numbers conjoint method is used in this paper to analyze the achievement goals of undergraduates in the learning of calculus. One hundred and seven selected Bachelor of Science (Hons) Mathematics and Bachelor of Science (Hons) Actuarial Science students from one public university in Klang Valley, Selangor, participated in this study. The data for this study, which was distributed via Google form, was based on a previous study's Achievement Goals Questionnaire. The fuzzy number conjoint method with similarity measure based on geometric distance, ambiguity, value, area, left and right height were used to calculate and analyze the data gathered from respondents' opinions of attributes for each linguistic value. The priority of the degree of agreement among undergraduates on the achievement goals in the learning of calculus is worrying as they may not learn all that they possibly could in this subject , getting better grades than most other students , followed by avoiding performing poorly compared to other students in this subject , and doing better than other students with an overall ranking as follows .. The findings of this study can be used to assist and guide academicians and mathematics educators in enhancing students' achievement goals for calculus learning.
