Abstract

Mathematics is a subject that exists at all levels of study and requires the ability to think logically, organize, and demonstrate. One of the materials that require this ability in mathematics is the limit function material. The boundary functional material becomes the basis for mastering the next material, namely derived material. The fact that students do not have a solid understanding of the limit function literature indicates that students do not do well academically at this level. This is because students have difficulty and make mistakes in understanding concepts, facts, and procedures in the limit function literature. Vygotsky's theory can be applied to the matter of limit functions. Vygotsky applies the Zone of Proximal Development (ZPD) which is a level of development slightly above a person's current level of development. When children have learning difficulties, Vygotsky suggests that teachers can use scaffolding as support or assistance through someone who is more proficient in mastering the material to help solve problems, problems for people with higher levels of cognitive development.

Abstract

This study aims to find out the issues or problems that become the direction and trends of mathematics education research as an effort made by teachers in responding to challenges in 21st-century learning. The writing in this study uses a literature study by utilizing scientific journals published by the Creative Mathematics Journal- Innovative (KREANO) from 2016 to 2021 by involving a total of 156 scientific journal items. The theme of last year's study was dominated by the process of mathematical thinking skills with a focus on secondary education students as research subjects. Currently, the research theme of mathematics education is studying with a focus on developing media or making a product and learning device as well as designing a project-based learning model with a subject focus on prospective teachers and students of secondary education as research subjects. Future research in mathematics education will also examine mathematical thinking skills by creating technology-assisted learning in an open, flexible project-based learning environment so that students can collaborate in developing their potential. Therefore, teachers are required to be able to implement a curriculum to innovate in learning with various approaches, models, strategies, methods, assessments, and all related matters, which are effective
