Implementasi Geogebra Integrasi PowerPoint 365 terhadap Kemampuan Representasi Matematis pada Siswa Kelas XII

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan Geogebra integrasi PowerPoint 365 terhadap kemampuan representasi matematis siswa kelas XII. Penelitian ini adalah pra-eksperimen dengan pendekatan kuantitaif menggunakan teknik pengambilan sampel yaitu cluster random sampling. Pengambilan data dilakukan dengan menggunakan tes kemampuan representasi matematis(pretest dan posttest),  angket respon siswa dan lembar observasi aktivitas siswa. Teknik analisis data yang digunakan adalah analisis statistika deskriptif dan inferensial. Hasil analisis statistika deskriptif menunjukkan: (1) rata-rata hasil pretest yaitu 47,78 (kategori sangat rendah). Rata-rata hasil posttest yaitu 88,89 (kategori tinggi), (2) hasil posttest menunjukkan bahwa ketuntasan klasikal tercapai sebesar 100%, (3) rata-rata gain ternormalisasi sebesar 0,8 (kategori tinggi), (4) rata-rata presentase aktivitas siswa sebesar 90,5% (sangat aktif), (5) rata-rata persentase respon siswa sebesar 92% (baik sekali). Hasil analisis statistika inferensial menunjukkan: (1) nilai rata-rata siswa yang diajar menggunakan Geogebra integrasi PowerPoint 365 lebih dari 70, (2) nilai rata-rata gain ternormalisasi lebih dari 0,3 (kategori sedang), (3) rata-rata ketuntasan klasikal lebih dari 85%. Secara umum dapat disimpulkan bahwa penggunaan Geogebra integrasi PowerPoint 365 berpengaruh terhadap kemampuan representasi matematis siswa kelas XII.Kata Kunci: PowerPoint 365, Geogebra, Kemampuan Representasi Matematis This study aims to determine the effect of the application of Geogebra integration PowerPoint 365 on mathematical representation ability in class XII. This research is pre-ecperiment with quantitative approach with techniques sampling is cluster random sampling. Data collection was carried using test result of mathematical representation ability (pretest and posttest), student quistionnaire responses, and observation sheets of student actvities. The data analysis technique used is descriptive and inferential statistical analysis. The result of descriptive statistical analysis showed: (1) the average pretest result were 47,78 (low category). The average posttest result were 88,89 (high category), (2) the posttest result show that classical completeness is achived 100%, (3) the average normalized gain is 0,8 (high category), (4) the average percentage of activity students by 90,5% (very active), (5) the average percentage of students quistionnaire responses by 92% (very good). The result of inferential statistic analysis show: (1) the average value of students tought using Geogebra integration PowerPoint 365 was greater than 70, (2) the normalized gain average value was greater than 0,3 (medium category), (3) the average classical completeness greater than 85%. In general it can be concluded that implementation Geogebra integration PowerPoint 365 has an effect on student mathematical representation ability.Keywords: PowerPoint 365, Geogebra, Mathematical Representation Ability
