Abstract

In the present digital age, the utilization of e-learning platforms in education is becoming increasingly significant. This is especially true in the field of Mathematics Education, where there exists a challenge to enhance students' critical and creative thinking abilities. This research aimed to investigate the improvement in students' critical and creative mathematical thinking abilities through the implementation of a team project-based model, Flip-a-Team, within UNP's e-learning platform. A quasi-experimental research design was used, applying a post-test control group approach. The sample involved 64 students from a mathematics study program who were enrolled in the July - December 2022 semester. These students were divided into two groups: 32 students in the experimental group (Class A) that was instructed through the Flip-a-team model, and 32 students in the control group (Class B) that experienced problem-based learning. Based on an independent t-test, the results demonstrated that the mathematical learning process incorporating the Flip-a-Team model had a positive and significant impact on the students' critical and creative mathematical thinking abilities. The Flip-a-Team model is recommended for implementation in mathematics instruction. The UNP e-learning platform could serve as a feasible solution for digitally based mathematics education, particularly in fostering students' critical and creative thinking abilities in mathematics.

Abstract

Riset ini didasari oleh defisit kemampuan komunikasi matematis peserta didik dalam mengartikulasikan ide secara lisan maupun tulisan, yang diperparah oleh dominasi pembelajaran berpusat pada guru serta keterbatasan perangkat ajar yang representatif. Sebagai solusi strategis, penelitian ini bertujuan untuk mengonstruksi Lembar Kerja Peserta Didik (LKPD) berbasis guided inquiry pada materi lingkaran yang memenuhi kriteria valid, praktis, dan efektif. Metodologi pengembangan mengacu pada model Plomp yang mencakup tiga fase integratif: investigasi awal, pengembangan prototipe, dan tahap penilaian. Instrumen pengumpulan data meliputi angket, lembar observasi, serta tes kemampuan komunikasi matematis. Temuan penelitian menunjukkan bahwa LKPD yang dikembangkan mencapai skor validitas rata-rata 3,46 dengan kategori sangat valid. Aspek praktikalitas pada tahap small group dan field test masing-masing memperoleh persentase 91% dan 90,09% (sangat praktis). Lebih lanjut, efikasi perangkat terbukti melalui eskalasi signifikan pada perolehan skor peserta didik antara tahap pre-test dan post-test. Secara keseluruhan, LKPD berbasis guided inquiry ini dinyatakan layak secara metodologis dan empiris untuk digunakan sebagai sarana optimal dalam menstimulasi kompetensi komunikasi matematis siswa.
