Analysis of student's mathematical writing skill with two stay two stray models toward writing in performance tasks strategy at SLETV materials

Abstract

The aims of this research is to investigating the student's mathematical writing skill on doing exercise after studying with two stay two stray models toward writing in performance tasks strategy at SLETV materials. This research is qualitative research. The technique of collecting data is test method to collect the data of student's mathematical writing skill after studying with two stay two stray models toward writing in performance tasks strategy. The subject of this research are student's of 2nd grade in SMP Negeri 24 Surakarta year 2017/2018. The sampling technique is based of student's group with high achievement, medium achievement, and low achievement then from each group taken two students to analize the student's mathematical writing skill. The analize of data use three activities, there are reduction data, present data, and getting the conclusion. The result of the research: students number 19 with high achievement have all the aspec of mathematical writing, there are written text, drawing, and mathematical expression. Students number 23 with high achievement have all the aspec of mathematical writing, there are written text, drawing, and mathematical expression although the drawing aspec still not perfect. Students number 3 with medium achievement have all the aspec of mathematical writing, there are written text, drawing, and mathematical expression but the written text aspec still not perfect. Students number 22 with medium achievement have all the aspec of mathematical writing, there are written text, drawing, and mathematical expression but the mathematical expression and written text aspec still not perfect. Students number 17 with low achievement have all the aspec of mathematical writing, there are mathematical expression, drawing and written text but the drawing and written text aspec still not perfect. Students number 21 with low achievement have all the aspec of mathematical writing, there are mathematical expression, drawing and written text but the drawing and written text aspec still not perfect.
