Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penerapan media pembelajaran interaktif Desmos terhadap pemahaman siswa mengenai materi fungsi kuadrat. Penelitian dilakukan di SMP Swasta Utama Medan dengan menggunakan desain eksperimen One-Group Pre-test-Post-test. Sampel penelitian terdiri dari 27 siswa kelas IX yang mengikuti pembelajaran menggunakan media pembelajaran interaktif Desmos berbasis pendekatan Realistic Mathematics Education (RME) pada topik fungsi kuadrat. Intrumen penelitian terdiri atas soal-soal pre-test dan post-test yang telah dirancang untuk mengukur pemahaman siswa terhadap konsep fungsi kuadrat, khususnya mengenali jenis-jenis grafik fungsi kuadrat dan sifat koefisien fungsi kuadrat yang mempengaruhi perubahan bentuk grafik fungsi kuadrat. Hasil penelitian menunjukkan bahwa terdapat peningkatan nilai rata-rata dari 34,81 pada pre-test menjadi 70,37 pada post-test. Hasil uji-t menunjukkan bahwa terjadi peningkatan signifikan secara statistik () dan nilai probabilitas =  sehingga dapat disimpulkan bahwa penggunaan media pembelajaran interaktif Desmos memberikan pengaruh signifikan terhadap hasil belajar siswa pada materi fungsi kuadrat.

Abstract

Statistics is often considered difficult by high school students because the learning approach tends to be theoretical and less interactive, resulting in students' low mathematical understanding of concepts such as mean, median, and mode. This study aims to develop educational website-based learning media with a Problem-Based Learning (PBL) approach to improve students' mathematical understanding. The research method uses the Research and Development (R&D) model with the adoption of the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The research subjects were grade XI students of Imelda Private High School Medan who were divided into an experimental class (using PBL website media) and a control class (conventional method). Data were collected through validation sheets, student response questionnaires, and mathematical understanding tests (pre-test and post-test). The results of the website media were declared "Very Feasible" with a validation score of 95%. The effectiveness results showed a significant increase in the average post-test score (63.91) from the pre-test (26.26), with a Normalized Gain (N-Gain) score of 0.51 (category "Medium"). The student response questionnaire also showed a positive response, with an average of 82.57% ("Effective"). Implications This media, which has innovative features such as a statistical calculator and Excel upload data analysis, serves as an effective scaffold for PBL, encouraging students to conduct data analysis independently, and helping shift 73.9% of students from the "Very Low" ability category.
