Abstract

This research is a descriptive study that aims to describe the ability to understand mathematical concepts in grade 12 7 in SMA 1 Palembang through learning assisted Grapher application on android. The subjects of this study consisted of 30 students. The instrument used was observation and test. Observations were used to collect data about learning and tests were used to see the ability to understand students' mathematical concepts. The results of the study concluded that the ability of students' understanding of rational function material, limitless to algebraic functions and infinite limits on categorized trigonometric functions was quite good. In the material of rational function, students were misconstrued due to being trapped in images that appear to be congruent. Even though the pictures were not congruent. Still related to the material of rational function, the presentation of a picture that was not right in terms of scale and form of sketches caused students to misinterpret the problem and make conclusions. Specifically for infinite limit material for both algebraic and trigonometric functions, the low scores of students on the concept comprehension tests were caused by students being less careful in calculating.

Abstract

The purpose of this classroom action research is to improve mathematics learning outcomes of students in XII Science 9 Senior High School Number 1 through GeoGebra assisted learning. Subject of this research are 29 students. The lesson taught in this study are maximum and minimum value, monotonicity, slope, and concavity of trigonometric function. First cycle was held in 3 meetings and the second cycle held in 2 meetings. Instrument used is a test of learning outcomes and observation. Learning outcomes test is used to find out student’s achievement in each cycle and observation used to collect data during learning process. The data are analized quantitatively and descriptively. Results of the study indicate that the average score of XII Science 9 in the first cycle is 50,00 and in the second cycle is 82,76. The result of this study show that GeoGebra assisted learning can improve mathematics learning outcomes which is equal to 80% students have achieved completeness in second cycle
