Abstract

This article aims to describe the mistakes made by students in solving mathematical problems in trigonometric materials. This research is a descriptive study with the object of research is class X-MIA MAN 1 Padangsidimpuan with heterogeneous levels of ability. The instrument collects data using essay tests. Data analysis is carried out by reducing the data in the form of paragraphs and images, then drawing conclusions. The results of this study show that the common mistakes made by students in this study are more errors in understanding the problem, errors in planning problem solving, errors in doing calculations and errors in re-examining the answers, namely wrong in understanding the meaning of the question information, not fully understanding the formulas that must be used in doing the questions, errors in the calculation process and students did not find the results requested in the questions,  and the error did not re-check the answer and did not carry out the stages of re-checking.

Abstract

This study aims to determine students' communication skills. The research method used is qualitative. Qualitative research method is a research that is used to examine natural objects where the researcher is the key instrument. Data was collected through observation and analysis of student answer sheets. The results of this study were that students' communication skills were still low on triangles and quadrilaterals. This can be seen in the results of student answer sheets, teachers need to improve student abilities again. Qualitative research method is a research that is used to examine natural objects where the researcher is the key instrument.

Abstract

Student learning outcomes are still low due to the low ability of teachers to utilize learning media in the learning process. This makes it increasingly difficult for students to understand the material presented by the teacher, because they become less active and pay less attention to the teacher's explanation of the material presented. This research formulates the question of whether the use of statistics whiteboard media in statistics teaching materials at SMA Negeri 1 Rao Class XII IPA 1 SMA Negeri 1 Rao in mathematics education can improve student learning outcomes. The approach used in this research is classroom action research (PTK) using the Kurt Lewin model which consists of the stages of planning, taking action, observing and reflecting. The subjects of this research were students of Class XII Science 1 SMA Negeri 1 Rao. The data collection tools used are observation to observe student activities and teacher tests to measure student learning outcomes, interviews to collect data, and data collection on statistical board media.
