Abstract

Mathematics is a subject that plays an important role in aspects of life, therefore mathematics lessons are given to students at every level of education so that they are able to master mathematical skills. One of the most important abilities in learning mathematics is the ability to fluency in procedures. This study aims to analyze students' procedural fluency in solving linear program questions in class XI SMA Bidayatul Hidayah. This research uses a qualitative approach that is descriptive. The research instrument used was in the form of test sheets and interview guidelines. The results showed that students who have high mathematical procedural skills are as many as one student because they meet the three indicators used in this study, while as many as two students only meet the second indicator of students' mathematical procedural fluency skills, besides that the other two students have fluency skills. low mathematical procedural because it does not meet all the indicators used in study.

Abstract

Students have commitment to important tasks as a form of responsibility for themselves to be able to complete all assigments despite difficulties. The existence of a commitment to the task will be an independent learning experience to measure the extent to which students understand the material that has been learned. This study aims to describe commitment to tasks in learning mathematics. The subjects of this study were 20 students of class VIII-3 at SMP Negeri 1 Rancabungur. This type of research is qualitative with descriptive methods. The data collection technique used a questionnaire based on the commitment indicator on the task as many as 32 items. The results showed that the overall percentage was 42%, meaning that almost half of the students were committed to the task. The percentage obtained is still at a low point (<50)so that efforts are needed to increase commitment to the task so that students can create a sense of learning and practice to achieve good learning achievement.

Abstract

Batik is a world cultural heritage owned by Indonesia. In Krebet village, Sendangsari, Pajangan, Bantul, Batik is painted on wood or known as wooden batik. This wooden batik decorates household appliances. Wooden batik of Krebet has not been maximally utilized in learning science, especially mathematics. Even though there are many mathematical concepts contained in it. This study aims to explore mathematical concepts in wooden batik, especially geometric materials. In this study, researchers used exploratory research with an ethnographic approach. The instrument in this research is the human instrument, where the researcher is directly related to the research and acts as a data collector through observation, library data collection, documentation, and interviews. Data analysis techniques are carried out by domain and taxonomic analysis.
