This study discusses the process of developing and validating a conceptual and procedural
understanding test for integral calculus. The aim was to produce a valid and reliable test to measure students’
understanding of both types of knowledge, conceptual and procedural, in integral calculus. The test questions
were developed in four main stages consisting of eight distinct systematic phases. The validation process started
with discussions with content experts followed by a pilot test. Four experts provided inputs for the content
validity purposes. Their inputs were used to produce a valid set of Integral Calculus achievement test
comprising 15 questions. A pilot test assessed the reliability and fit statistics of the test. The test was
administered to 79 students in a higher learning institution selected randomly from a group of students taking
Integral Calculus. The data was analyzed using Winstep’s software to ensure the quality of the questions. The
analysis was done separately for each construct. The results indicated excellent item reliability indices with very
good index separation values for both constructs. However, the person reliability indices for both constructs
were only fair to good. Likewise, the results revealed only fair index separation values. In terms of fit statistics,
three conceptual understanding items were replaced with a new item. Meanwhile, for procedural understanding
items, two items were combined and one misfitting item was modified. Based on the experts’ views and
empirical data, the test questions were modified before they were used in the actual study.
Key words: Achievement, conceptual understanding, integral calculus, procedural understanding, rasch measurement model, ,
