However, learning such material is not a trivial task. Based on our informal observation regarding studentsâ€™ test, most of them could not correlate Big-Oh equation to real program execution. This paper proposes JCEL, an educational tool that acts as a supportive tool for learning algorithm time complexity. Using this tool, user could learn how to correlate Big-Oh equation with real program execution by providing three components: a Java source code, source code input set, and time complexity equations. According to our evaluation, students feel that JCEL is helpful for learning the correlation between Big-Oh equation and real program execution. Further, the use of Pearson correlation in JCEL shows a promising result.}, number={1}, journal={Journal of Information Technology and Computer Science}, author={Kurniawati, Gisela and Karnalim, Oscar}, year={2018}, month={Jun.}, pages={1–15} }
