Abstract

One of the factors that influences a person's level of success in the learning process is self-efficacy. Low self-efficacy and student learning outcomes in the learning process are the background for this research. In order for student self-efficacy and learning outcomes to increase, there needs to be a learning process that makes students learn meaningfully, one of which is the model discovery learning. The purpose of writing the article is to see whether there is an increase in student self-efficacy after implementing the discovery learning model and whether there are differences in learning outcomes between the application of the model discovery learning and student learning outcomes using the scientific approach. The method in this research uses experimental research methods with research instruments in the form of questionnaires given to students before and after the learning process using discovery learning models and learning outcomes tests. Based on the calculations, it was found that there is an increase in students' self-efficacy after applying the model discovery learning, with a value  of 0.43 categorized as a "moderate" improvement. This indicates that the discovery learning model positively contributes to enhancing students' self-confidence. This means that there is an increase in student self-efficacy by implementing the model discovery learning. For student learning outcomes, the calculation results obtained are ????ℎ???????????????????? = 2.38 and ???????????????????????? = 1.67. This means that student learning outcomes by applying the model discovery learning are better than by applying learning using the scientific approach.

Abstract

The development of 21st-century skills, particularly collaboration and critical thinking, has become a central objective in contemporary mathematics education. The Realistic Mathematics Education (RME) approach is considered a promising intellectual strategy for supporting these competencies through contextual problem-solving activities and structured social interactions. However, emperiecal evidence on the simultaneous contribution on both critical thinking and collaborative skills remains limited. This study aims to assess the effect of the RME approach on students’ critical thinking and collaborative skill in mathematics learning. A quantitative approach using a quasi-experimental pretest–posttest control group design involving sixty students, divided into an experimental group receiving RME instruction (n = 30) and a control group receiving conventional instruction (n = 30). The research instruments included a critical thinking skills test and an observation-based collaboration skills assessment. Data were analyzed using Multivariate analysis of Covariance to assess the combined effects of RME while controlling for initial abilities .The results revealed that the experimental group ashowed significantly higher posttest scores in critical thinking skills (M = 82.15) compored to the control group (M = 70.46), with N-Gain scores of 0.61 and 0.35, respectively. Similarly, students’ collaborative skills in the experimental group (M = 84.27) were higher than those in the control group (M = 71.15). Multivariate analysis confirmed a statistically significant effect of RME on both critical thinking and collaboration. These findings suggest that RME effectively enhances students' cognitive and social competencies and can serve as an alternative strategy for mathematics instruction.
