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

This study aimed to improve student’s problem-solving abilities of tangent circle equations using discovery learning. This research was done in class XI IPA 4 SMA N 1 Palembang. This research method is used Classroom Action Research with discovery learning models. The instrument is used test instrument in the form of an evaluating matter of the tangent circle equation in the description form and the observation sheet for observation of the learning activity of the students. The results of the study showed that there is an increase in students' problem-solving abilities in tangent circle equation material using discovery learning. This increase can be seen from the results of the post-test students with an average score of 93,6 which increased when compared with the results of the pre-test with an average value of 58,2. The percentage of students who complete learning increases from 30% pre-test to 100% at post-test with KKM (maximum mastery criteria) ≥ 70. Based on the data analysis, it can be concluded that learning with discovery learning models can improve student learning outcomes in the tangent of circle equation material.
