Abstract

This research aims to provide an overview and determine the influence of ISLE (Investigative Science Learning Environment) based STEM (Science Technology Engineering and Mathematics) physics learning on students' understanding of physics concepts. This research is a quantitative descriptive study using the one group pretest-posttest method. The population in this study were students of class XI Science at MAN Ende for the 2024/2025 academic year and the sample was students of class. Sampling in this research used purposive sampling technique. The data collection method consists of administering tests and LKPD. The data obtained from the research sample was in the form of test scores on students' understanding of physics concepts on global warming materials. Normality test and t-test are the data analysis techniques used. From the results of data analysis, it is known that ISLE based STEM physics learning has an effect on students' ability to understand physics concepts according to the One-Sample Test carried out with sig. (One-Sided p) is 0.001 < 0.05. Students' ability to understand physics concepts increased after implementing ISLE-based STEM physics learning with an average pretest score of 57.119 and an average posttest of 89.381 with the difference between the posttest and pretest scores being 32.252 points. While working on the LKPD students are more active in working with their team in solving problems and students are trained to understand the procedures for working on them. Apart from that, by implementing this learning, it can encourage students to hone their own thinking patterns so that they are able to explain the students' own understanding of physics concepts based on what they have observed and understood.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penggunaan aplikasi Mathos AI dalam meningkatkan kemampuan pemecahan masalah matematika peserta didik. Jenis penelitian yang digunakan adalah pre-eksperimen dengan desain one group pretest-posttest. Subjek dalam penelitian ini adalah 23 siswa kelas X-3 SMAN 1 Nangapanda yang dipilih dengan teknik sampel jenuh. Pengumpulan data dilakukan melalui tes kemampuan pemecahan masalah berdasarkan indikator Polya dan lembar observasi keterlaksanaan pembelajaran. Hasil analisis menunjukkan adanya peningkatan skor rata-rata dari 75,00 pada pretest menjadi 100,00 pada posttest. Uji hipotesis menggunakan Wilcoxon Signed Rank Test menghasilkan nilai signifikansi sebesar 0,007 (< 0,05), yang berarti terdapat perbedaan yang signifikan antara hasil pretest dan posttest. Hasil ini menunjukkan bahwa penggunaan aplikasi Mathos AI efektif dalam meningkatkan kemampuan pemecahan masalah matematika peserta didik. Aplikasi ini dinilai mampu membantu siswa memahami soal, merencanakan solusi, menyelesaikan langkah-langkah secara sistematis, dan melakukan pengecekan kembali jawaban dengan lebih baik. Penelitian ini merekomendasikan pemanfaatan Mathos AI sebagai media pendukung pembelajaran matematika yang adaptif dan inovatif di era digital
