Investigation the effect discovery-based learning on students' metacognition in solving rainbow 2-connection numbers

Abstract

This study aims to investigate the success of the application of discovery based learning model to improve students' metacognition in solving the problem of mathematical modelling rainbow 2-connection numbers. The research model used is a mixed method that is a combination of quantitative and qualitative models. The quantitative model used a t-test to test the student learning outcomes while questionnaires and interviews are used to achieve students' metacognition skills. The results showed that the learning model of discovery based learning can improve students' metacognitive skills in solving mathematical modelling problem of rainbow 2-connection number, as indicated by the difference of t-test between experimental class and control class pre-test score of two groups [[t(48) = 3,808, p > 0,005]] not significant. For the post-test class experimental was 65, 10 (SD = 11,875) and for control class was 53,85 (SD = 8,274). There is a difference between the two significant mean post-tests [t(48) = -11,25, p < 0,005]. The results of questionnaires and interviews also showed that the DBL model can improve students' metacognition skills, especially in conducting activities to collect, compare, categorize, analyse, integrate, organize materials and make conclusions.
