ABSTRACT

 As recommended by the Education Blueprint 2014-2020, education system in Bhutan transformed
 from traditional instructions to technology-enriched and enabled teaching and learning environment
 with adoption of emerging and relevant technology to produce the globally competent learners. The
 integration of educational technology in the teaching and learning of definite integral creates a
 conceptually rich learning environment. From this perspective, this study aims to
 ascertain the effectiveness of a computer-assisted instruction method using GeoGebra in
 developing the conceptual understanding of definite integral for grade 12 students. This study
 employed a quasi-experiment static-group comparison design with 60 students from
 Gongzim Ugyen Dorji Central School in Haa. The students were divided into two equal groups.
 Group ‘A’ used the GeoGebra software, while group ‘B’ used the conventional method to learn
 definite integral. The data were collected through Definite Integral Knowledge Test. An
 Independent sample t-test was employed using the Statistical Package for the Social Sciences
 (SPSS 22.0). Findings of the study showed that students who were taught using GeoGebra

 outperformed those who learned through conventional methods. The results confirmed that
 GeoGebra software is capable of enhancing and significantly improving students’ conceptual
 understanding of definite integral.
