Abstract

The purpose of this study was to determine eighth grade student problem-solving ability on number pattern material. This study was held academic year focused on assessing students learning styles. The methods used in this study were questionnaires, tests, and interviews. The results showed that class VIII students consisted of 26 students had visual learning styles, 24 students had auditory styles and 16 students had kinesthetic styles. Subjects taken in this study were 2 students from each learning style, then the subject was given a test to describe the number pattern material and conducted an interview. As a result, based on the analysis of the problem-solving ability stages, students with visual and auditory learning styles were able to reach the stage of understanding the question / problem, designing and choosing a solution strategy, and solving problems with a mathematical model, but have not yet reached the stage of re-checking the solutions obtained. On the contrary, Students with a kinesthetic learning style have been able to reach the stage of understanding the question / problem, but have not been able to reach the stage of designing and choosing a solution strategy, or solving problems with mathematical models, and even re-checking the solutions obtained. This shows that the problem solving ability of students with visual and auditory learning styles is better than students with kinesthetic learning styles.

Abstract

The background of this research is the low activity and achievement of students' mathematics learning, one of which is due to the selection of learning models that are less varied. The activities of students are only limited to listening, taking notes, then doing practice questions. Discovery Learning is a learning model that directs students to be able to find concepts through the learning process they do which is expected to increase the activities and learning achievements of students. This type of research is a classroom action research (PTK) which is carried out in two cycles and each cycle contains the stages of action planning, action implementation, observation, and evaluation, as well as a reflection stage. The results showed that there was an increase in the activity and learning achievement of students where the learning activities of students in the first cycle with an average score of 10.51 were categorized as high, while in the second cycle with an average score of 13.67, they were categorized as very high. The average score of the learning evaluation results of students has increased in each cycle, namely in the first cycle the average score of the learning evaluation results was 72.65 with a percentage of 62.07% completeness and in the second cycle the average score of the learning evaluation results was 79.24 with a percentage of completeness of 86.21%. Based on the achievements obtained, it can be concluded that the Discovery learning model can increase the activity and learning achievement of students in learning tangents to circles.
