| This study aims to develop and determine the effectiveness of Bar Model Fraction Kit based on students’ achievement in answering Higher Order Thinking skills (HOTS) word problems. In order to enhance the validity of the instrument, four experts had reviewed the instrument. The Cohen kappa value is 0.75. This indicates a “good” extent of agreement. There were 15 students involved in the pilot test. The students used the Bar Model Fraction Kit to answer the test items. From the analysis, it was found that the Cronbach alpha coefficient value is 0.765. This shows that the Bar Model Fraction Kit has acceptable reliability. A total of 48 Year 5 students from Batang Padang District, Perak were involved in a quasi-experiment using pre-test and post-test. The students were divided into a control group and a treatment group. The control group (n=23) used the teaching and learning process (T&L) with conventional method, while the treatment group (n=25) used the T&L using the Bar Model Fraction Kit. Data were analysed using Mann-Whitney Test. The results indicated that during post-test, students who used Bar Model Fraction Kit showed significant improvement in their HOTS level (p=0.000). In conclusion, the students who undergone T&L using Bar Model Fraction Kit performed better than the students in the conventional group. The Bar Model Fraction Kit has effectively improved the performance of students in answering HOTS word problems involving addition and subtraction of fraction. |
