The Development and Usability of KITATORA for the Topic of Algebraic Expressions in Form 1

Abstract

This study aimed to develop KIT Tambah Tolak Algebra (KITATORA), which is designed to teach students how to add and subtract two or more algebraic expressions, according to the Secondary School Standard Curriculum (KSSM) Mathematics at Form 1 in Malaysia. The study also sought to determine the validity and usability of KITATORA. The research design used for this study was Design and Development Research (DRD). The sample for the validity of KITATORA included a mathematics lecturer from a public university and two experienced mathematics teachers. The study sample consisted of 30 Form 1 students from a school in the state of Selangor. This study used two types of instruments: the Kit Validation Assessment Form (KVAF) and the Kit Usability Survey (KUS). The validity, reliability, and usability data were analysed using Content Validity Index (CVI) calculations, Cronbach's alpha value, and interpretation of minimum scores. The study findings showed a CVI value of 1.00, a Cronbach's alpha value of 0.938, and an average minimum score of 3.83. In conclusion, this study suggests that KITATORA has satisfactory validity and usability. Therefore, teachers can use KITATORA as an alternative teaching aid for the topic of adding and subtracting two or more algebraic expressions. The educational significance of KITATORA lies in its ability to enhance students' understanding of algebraic concepts while promoting greater engagement with the subject, making algebra more accessible and enjoyable for learners.
