Penerapan Teknik Modelling melalui Bimbingan Kelompok untuk Meningkatkan Growth Mindset Siswa

Abstract

This study aimed to determine the effectiveness of applying modeling techniques through group guidance to improve the growth mindset of students at SMP Negeri 8 Banda Aceh. The study employed a quantitative approach with a pre-experimental method using a one-group pretest-posttest design. The subjects consisted of six ninth-grade students selected through purposive sampling based on their low growth-mindset scores. Data were collected using a growth mindset questionnaire based on Carol Dweck's theory, covering six aspects: motivation, attitude, challenge, grit, adversity, and positive mindset. The data were analyzed using descriptive statistics, the Shapiro-Wilk normality test, a paired sample t-test, and an N-gain analysis. The results showed that the average score increased from 62.6 on the pretest to 81.7 on the posttest. The average percentage across all aspects also increased from 53.83% to 81.83%. The paired sample t-test yielded a significance value of 0.000 (p < 0.05), indicating a significant difference between the pretest and posttest scores. Furthermore, the N-gain score of 0.73 (73.35%) indicated that the intervention was effective in improving students' growth mindsets.Keywords: Modeling Technique; Growth Mindset; Group Guidance.
