Students' conceptual understanding on acid-base titration and its relationship with drawing skills on a titration curve

Abstract

The study aimed to describe the conceptual understanding of acid-base titration and to know its relationship with drawing skills on a titration curve. This study used a quantitative approach with a type of correlational descriptive one. The study has been carried out with 54 undergraduate students of the Chemical Education Department at the Faculty of Tarbiyah and Teacher Training in State Islamic Institute of Tulungagung in the even semester of the 2018/2019 academic year. The data collection used test technique which is consisted of a written test and drawing skills of a titration curve using Ms. Excel. The data analysis technique used product moment correlation with the SPSS 17.0 program. The results showed that the average value of conceptual understanding in acid-base titration and drawing skills of a titration curve were 53.7 (medium) and 71.4 (good), respectively, with the number of students getting above average scores was 25 (46.3%) and 30 (55.6%), respectively. Based on product-moment correlation analysis, sig = 0.000 <0.05 means that there is a significant relationship between the conceptual understanding of acid-base titration with the skills of drawing the titration curve. Furthermore, the value of r = 0.526 correlation is included in the moderate category.
