PENERAPAN PENDEKATAN NARASI UNTUK MENINGKATKAN KETERAMPILAN PEMECAHAN MASALAH MATEMATIKA PENJUMLAHAN DAN PENGURANGAN PADA KELAS 1SD KRISTEN CITRA BANGSA MANDIRI
Abstract
This research is motivated by the low problem-solving skills of Grade 1C students
at SD Kristen Citra Bangsa Mandiri Kupang. The aim of this study is to improve
mathematical problem-solving skills, particularly in the topics of addition and
subtraction in that class.The research employs a Classroom Action Research
(CAR) method. Data collection techniques included observations of teacher and
student activities, as well as written tests. The instruments used were observation
sheets and test questions. The subjects of this research were 21 Grade 1C
students, consisting of 10 boys and 11 girls. Data analysis was conducted by
analyzing the results of observations and problem-solving tests.The findings
showed a significant improvement in problem-solving skills. Learning mastery
increased from 47.66% in the pre-cycle to 71.42% in cycle I, and reached 85.71%
in cycle II. Improvements were also seen in the observation results of teacher and
student activities. In cycle I, teacher activity reached 69.11% and 70.58%, while
student activity according to observer one was 65% and 68.33%, and according to
observer two was 60% and 71.66%. In cycle II, observer one recorded an increase
to 81.66% and 83.33%, and observer two recorded 85% and 81.66% for teacher
activities, and 81.25% and 84.37% for student activities. Based on these results, it
can be concluded that the use of a narrative approach is effective in improving
students’ problem-solving skills in addition and subtraction material.
