Abstract

Most of the students needed help comprehending the geometry material concepts provided by the teacher. Learning media is one aspect that influences students' comprehension of geometry concepts. With the current situation, the use of the learning media such as pictures in a book or color-shaped paper does not relevant anymore. This project aims for a valid two-dimensional learning media, Pose Estimation Machine Learning (PEML), following students' characteristics and cognitive development. The developed online media facilitates visuals and allows students to move and perform motoric activities to represent the shapes. The method of the research was by using adjusted R&D steps: 1) preliminary investigation, 2) design, 3) realization, 4) test, evaluation, and revision, and 5) implementation. The participants of this study are second-grade students in a private elementary school in Central Jakarta. Data from the observation, students' worksheets, and interviews show that students were enthusiastic during the learning while they could still achieve the learning outcomes. The result indicates that PEML can be a medium for introducing two-dimensional topics.

Abstract

This study aimed to describe the process of learning mathematics in hybrid learning using a problem-based learning model. Furthermore, investigate the performance of students' problem-solving abilities in hybrid learning using problem-based learning. This case study research was conducted in one of the secondary schools in Bogor, Indonesia with a total of 20 students (13-15 years old) and a sample of six students who were selected based on convenience sampling. Data were collected through participant observation and written test. Researchers carry out problem-based learning on the material of a two-variable system of linear equations. The results showed that the hybrid learning process went smoothly. Students were enthusiastic about new media of learning. However, researchers found differences in the strategies used by students at home and school. Students' problem-solving ability to understand the problem is in a good category; devising a plan has a good enough category; carrying out a plan is not good enough; looking back is still in the very poor category.
