Abstract

Abstract. This study aims to determine whether there is an influence of the problem based learning model integrated with video animation on the mathematical problem solving abilities of class VIII students. This research was conducted at SMP Negeri 6 Percut Sei Tuan, TA 2022/2023. The research method used is a quasi-experimental design method. The sample in this study consisted of two classes namelyclass VIII-3 as the experimental class and class VIII-4 as the control class. The experimental class uses a problem-based learning model integrated with video animation and a control class with conventional learning. Obtaining the average score of the final test (posttest) of the experimental class students is equal to 89.22, whereas in the control class the average result of the student's final test score was 72.55, in the hypothesis test, the results obtained from the average difference test (t-test) with statistical values t_hitung>t_tabel(10.56 > 1,671 ) which means there is an influence from the usea problem-based learning model integrated with video animation that is applied to the experimental class. This indicates that the mathematical problem solving abilities of the experimental class students are better than the control class.

Abstract

To make students actively involved in learning to grasp mathematical higher-order thinking skills (MHOTS) is not easy. Meanwhile, the ability is so important for students to master for it takes place when students continue their studies to a higher level as well as work within a variety of professions, especially in the era of the industrial revolution such nowadays. Many factors affect students' thinking abilities, including learning factors. This study, which implemented constructivism-based learning, aims to investigate the role and contribution of constructivism-based learning approaches as well as mathematical prior knowledge (MPK) to the achievement of MHOTS of middle secondary school students. The data tested through Multivariate Analysis at the 0.05 significance level. In general, this study found that: (1) In the experimental class, the learning approach plays an important role in the way it increased students' MHOTS significantly. (2) The average contribution of constructivism-based learning to MHOTS was at the range of 18% to 57%. (3) Student activity in learning increased significantly. (4) In some cases, there is an effect of interaction between learning factors and MPK towards the achievement of MHOTS. The study recommended the teachers to have courageous in implementing constructivism-based teaching and learning to improve students’ MHOTS.
