ANALISIS KESULITAN SISWA DALAM MEMECAHKAN MASALAH FISIKA BERBENTUK GRAFIK DENGAN TES DIAGNOSTIK
Abstract
This study aims to find out problem solving skills in the form of graphs and difficulty profiles, especially in straight motion
material. This type of research is qualitative research. This research was conducted at SMA Negeri 1 Onanrunggu in the odd
semester of the 2020/2021 school year. The subject of this study was a grade XI MIA 1 student who was able to take part in
online learning. The instruments used in this study are diagnostic tests in the form of descriptions that have passed the stage
of instrument validation tests. The analysis is done using descriptive percentages. The results showed that the percentage of
each ability began with graph interpretation capability (50.60%), predicting ability (67.86%), and transformation ability
(67.63%). Students' difficulty profiles are based on KKM achievement, prerequisite knowledge, material profiles,
misconceptions, and troubleshooting stages. Based on the mastery of KKM, students still have difficulty for all indicators. For
the profile of students' difficulties based on their pre-existing knowledge, students still have difficulty in the counting
operations section. For student difficulty profiles based on material profiles, students still have difficulty for all sub-materials
especially acceleration. As well as the latter, the student's difficulty profile is based on the stages of problem solving. The
difficulty of students is increasing from the lowest stage, which is the stage of understanding the problem and the highest
stage is the review stage.
