Abstract

The purpose of this study was to examine the mathematical concepts of students in solving the problem of polyhedron of cubes and cuboids with assisted of Schoology media. This research uses qualitative methods with descriptive approach. This study describes the ability to understand mathematical concepts that owned of students with Schoology media. Research subjects is three students selected by purposive sampling based on conditions and situations that occured during the current co-19 pandemic. The data collection used consists of tests of understanding the ability of mathematical concepts. Based on the results of research showed that the ability to understanding students' of mathematical concepts with Schoology-assisted able to provide understanding of material polyhedron of cubes and cuboids by the average results of students getting value 91,67. Where the first student is able to reach an understanding indicator of mathematical concepts from given by agreeing to the concept, classifying objects according to certain properties, giving concepts in various forms of mathematical representation, explaining the relationship between one concept with another concept, and applying the concept in problem solving . While the second and third students can only reach four indicators from the second indicator given. Nevertheless, students show positive responses to Schoology media. Keywords: Understanding Mathematical Concepts, Schoology Media

Abstract

The purpose of this research is to analyze how students' mathematical literacy skills in online learning are viewed from self-efficacy. The method used in this research is a qualitative method with an analytical descriptive design. Data was collected using a self-efficacy questionnaire consisting of positive and negative statements and a mathematical literacy test. Data analysis was carried out by classifying students' self-efficacy into high, medium, and low categories by selecting 2 students for each category with the help of Microsoft Excel. Based on these data, it was found that students who had high self-efficacy were able to answer mathematical literacy questions on the indicators of formulating, using, and interpreting, but not completely and systematically. Students with medium self-efficacy are only able to complete level 1 mathematical literacy on indicators to formulate accurately, completely, and systematically. Students who have low self-efficacy are not able to solve mathematical literacy problems completely and systematically.
