Analysis of problem-solving skills in material probability in Kanisius Pakem vocational high school

Abstract

The purpose of this study was to describe the learning process by using the Problem Based Learning model on the topic of probability for Kanisius Pakem Vocational High School students, as well as to describe the problem-solving skills of Kanisius Pakem Vocational High School students after the implementation of learning trajectories on the topic of probability. The type of research used is design research. Data collection techniques are used, namely observation of the learning process. Then the data is analyzed by reducing data, presenting data, and concluding the results of the study. The learning trajectory was tested on 24 students of class X Kanisius Pakem Vocational High School. The research instruments used were field notes and student test sheets. The learning process consists of five-stage, namely the orientation of the students to problem regarding probability, organizing students to learn related to the material probability, guiding individual/group experiences on the learning process material probability, developing and presenting the work obtained from group discussions, and conclude the results of the learning process that has been done. From the results of tests obtained by students after the learning process, four aspects of problem-solving ability will be reviewed. Viewed from the aspects of understanding the problem, the students can describe things that are known and asked in the tests given. Viewed from the aspects of planning problem-solving, students can develop plans based on the information provided. Viewed from the aspect of implementing the plan, the students can translate the problem given in the form of mathematical sentences and students can make decisions in answering the problem. Viewed from the aspect of interpreting the results of the answers, the students have not all been able to verify the answers given.
