Abstract

One of learning media which is using in Problem-based learning that can improve students' conceptual understanding ability is GeoGebra. This study aims to: 1) describe the students' understanding of the concepts of SMA Negeri 1 Oheo. 2) determine the effect of problem-based learning assisted by the GeoGebra application on students' conceptual understanding at SMAN 1 Oheo. This research is pre-experimental research. The sampling technique uses simple random sampling. Class XI MIA as a research class. The data collection technique consists of students' conceptual understanding tests seen from the indicators explaining, understanding and concluding, as well as teacher observation sheets. The results of this study indicate that: 1) Students' conceptual understanding at SMAN 1 Oheo is in the high category where indicators of students being able to explain abstract concepts into a model have a 100% presentation, indicators of students being able to recognize and understand the main idea of a communication have a presentation 91.30%, and the student's indicator of being able to conclude from something that is already known material has an achievement of 78.26. 2) There is an effect of problem-based learning assisted by the GeoGebra application on students' understanding of concepts at SMAN 1 Oheo

Abstract

Mathematics learning in schools is still abstract and not yet relevant to students' lives. Mathematics learning should be linked to student activities such as scouting extracurricular activities. There are many scouting technical activities that can be used as contextualization in mathematics learning such as ceremonies, exploration, estimating, marching, pioneering, and semaphore. Thus, this study aims to identify mathematical concepts contained in scouting activities, especially in the construction of creative flagpole pioneering. This study is a qualitative study with an exploratory approach. Data collection methods used are observation, interviews, and documentation. The study was conducted on students who participate in scouting extracurricular activities at SMAN 2 Kendari, located on Jln. Sisingamangaraja, Rahandouna Village, Poasia District, Kendari City, Southeast Sulawesi Province. The results of the study show that in the pioneering flagpole creation building there are geometric concepts, namely rectangular, square, right triangle, acute triangle, obtuse triangle, right trapezoid, isosceles trapezoid, arbitrary trapezoid, right angle, acute angle, obtuse angle, overlapping lines and intersecting lines. and geometric transformations, namely rotation. These results provide recommendations to teachers to be able to use the pioneering building as an introduction to mathematical concepts.
