This study focuses on examining the effectiveness of the metacognitive guidance approach in mathematics education using the Systematic Literature Review (SLR) method. Metacognitive strategies are considered a relevant approach in 21st-century education because they encourage students to plan, monitor, and evaluate their thinking processes independently. The literature search was conducted via Google Scholar using appropriate keywords and yielded 306 articles in the initial stage. Subsequently, the selection process followed the PRISMA flowchart, including the removal of duplicate articles, screening based on titles and abstracts, and eligibility assessment through full-text review. From these stages, 12 articles meeting the inclusion criteria were selected as the basis for analysis. The study’s findings indicate that metacognitive guidance has a positive impact on mathematics learning, particularly on students’ problem-solving skills, critical thinking, mathematical literacy, and learning outcomes. This approach also enhances metacognitive awareness, enabling students to be more focused in selecting strategies, monitoring the learning process, and evaluating the results. Thus, this strategy is worthy of integration by teachers to strengthen the quality of learning and higher-order thinking skills.

This study is a literature review that aims to identify and analyze the application of GeoGebra applications in learning geometric transformations at the high school level. Geometric transformation is a material that requires high spatial visualization skills, so learning media are needed that are able to present concepts in a concrete and interactive way. GeoGebra, as a dynamic mathematics application, is considered capable of facilitating student understanding through direct visualization of transformation processes such as translation, reflection, rotation, and dilation. The study was conducted by reviewing 11 relevant scientific articles, published in the last five to ten years, and meeting certain inclusion criteria. The results of the analysis show that the application of GeoGebra in learning has a positive impact, both cognitively, affectively, and technically. GeoGebra is able to improve students' understanding of concepts, learning motivation, and learning outcomes. The implementation strategy includes the development of e-modules, digital teaching materials, problem-based learning, and application usage training. Overall, GeoGebra has proven to be valid, practical, and effective in supporting more interesting and meaningful learning of geometric transformations.

The goal of this study is to improve the mathematics learning outcomes of fifth-grade students in inclusive schools by applying the Jarimamatics approach of multiplying numbers from 6 to 9. This research was carried out at SDN 02 Taman Kota Madiun. The study method employed is Classroom Action study (PTK), which is conducted in two cycles. Each cycle includes planning, implementation, observation, and reflection. The subjects of this study were all eight class V pupils.Tests, observations, and documentation are some data collection approaches. The Jarimatika technique was used in this research to improve learning outcomes in mathematical multiplication. According to research data, the use of the Jarimatika technique can improve the multiplication skills of class V students. This is proven by an increase in student learning completion by 37.5% from cycle I to 75% in cycle II. Thus, using the Jarimatika approach can increase the accuracy of multiplication calculations for class V inclusive children. It is hoped that teachers can use the Jarimatika technique to improve mathematics learning in subsequent learning materials.
