PENINGKATAN KEMAMPUAN PEMECAHAN MASALAH MATEMATIS MELALUI PEMBELAJARAN SPLDV BERBANTUAN INTERACTIVE FLAT PANEL DAN CHATGPT PADA SISWA KELAS VIII SMPN 5 GEGERBITUNG
Abstract
Students’ mathematical problem-solving skills in Systems of Linear Equations in Two Variables (SPLDV) need to be improved through interactive learning that supports the exploration of solution strategies. This study aimed to analyze changes in students’ mathematical problem-solving skills through learning supported by an Interactive Flat Panel (IFP) and ChatGPT . A quantitative approach with a one-group pretest-posttest design was employed, involving 32 eighth-grade students at SMPN 5 Gegerbitung. The research instrument was a constructed-response test administered before and after the learning intervention. Data were collected through testing and analyzed using a paired-samples t-test, effect size, and normalized gain (N-gain). The results showed an increase in the mean score from 27.00 to 40.41 out of 48, with an N-gain of 0.64 (moderate category). The greatest improvement occurred in the indicator of checking the solution. Learning supported by IFP and ChatGPT has the potential to support mathematical problem-solving skills. Its implementation should include answer verification and teacher guidance.References
