Abstract

This research is motivated by the preliminary study of researchers at UPTD SMP Negeri 1 Gunungsitoli Idanoi, which is so far students are less active and tend to be passive in the learning process and students' mathematical literacy skills are still low. The purpose of this research was to determine whether the discovery learning model effect the students' ability in mathematical literacy skills. This research was conducted at UPTD SMP Negeri 1 Gunungsitoli Idanoi with the research object at 8th grade students in the 2022/2023 academic year, which is consist of 7 classes with a total of 208 students. The samples in this research were VIII-F class as the experimental class which was consist of 28 students and VIII-G class as the control class which was 27 students. This research is quantitative research using a quasi-experimental research method (quasi experiment design). The research instrument used was a mathematical literacy test of five items for the pre-test and five items for the pos-test. The results of the study obtained t-count = 1,915 and t-table = 1.674. Because t-count > t-table is 1,915 > 1.674, then reject Ho accept Ha which means "there is an effect of the discovery learning model on students' mathematical literacy skills

Abstract

This research is based on the results of a preliminary study conducted by researchers at SMP Negeri 1 Hiliduho. The problems identified were: (1) insufficient variety of classroom learning models and (2) students' lack of reflective thinking skills in solving mathematics problems. The purpose of this study was to determine the effect of the Collaborative Learning model on students' reflective thinking skills at SMP Negeri 1 Hiliduho. This quantitative study used a quasi-experimental method with a pretest-posttest control group design. The population was eighth-grade students, and the sample consisted of two classes: VIII-A as the experimental class and VIII-C as the control class. The instrument used was a descriptive test of reflective thinking skills. The research results obtained based on one-way hypothesis testing yielded a calculated t value of 4,628 and a t value of 2.024. Since t value > t value, or 4,628 > 2.024, H0 is rejected and Ha is accepted, meaning "there is an effect of the Collaborative Learning model on students' reflective thinking skills.
