ABSTRAKPenelitian ini bertujuan untuk mengembangkan dan menguji kevalidan, kepraktisan, dan keefektifan media komik dengan model problem posing pada mata pelajaran matematika di sekolah dasar. Metode penelitian yang digunakan adalah R&D dengan model pengembangan ADDIE. Kevalidan produk diperoleh melalui uji pakar dengan instrumen validasi pakar. Kepraktisan produk diperoleh melalui uji coba terbatas dengan instrumen angket. Keefektifan diperoleh melalui uji coba satu kelas dengan one grup pretest-posttest design kemudian hasilnya diuji menggunakan Paired Samples T Test. Hasil dari penelitian ini adalah media komik dengan model problem posing untuk meningkatkan kemampuan pemecahan masalah matematika. Media pembelajaran dinyatakan valid berdasarkan hasil uji pakar media menunjukkan bahwa media komik termasuk kategori tinggi, pakar materi menilai media komik termasuk kategori tinggi, dan pakar pembelajaran menilai media komik termasuk kategori tinggi. Media pembelajaran dinyatakan praktis berdasarkan hasil angket respon siswa menunjukkan bahwa siswa dapat menggunakan media komik. Media pembelajaran juga dinyatakan efektif berdasarkan hasil Paired Samples T Test pretest-posttest menunjukkan bahwa adanya perbedaan yang signifikan antara hasil belajar pada pretest dan posttest siswa. Kata kunci: pengembangan, komik, problem posing, kemampuan pemecahann masalah.
ABSTRACTThis study aims to develop and test the validity, practicality, and effectiveness of comic media with a problem-posing model on the subject of mathematics in elementary schools. The research method used was R&D with the ADDIE development model. The validity of the product was obtained through expert testing with expert validation instruments. The practicality of the product was obtained through limited trials using questionnaire instruments. Effectiveness was obtained through a one class trial with one group pretest-posttest design then the results were tested using the Paired Samples T Test. The results of this study are that comic media with problem-posing model improve mathematical problem-solving abilities. The learning media is declared valid based on the test results of media experts test showing that comic media is in the high category, material experts rate comic media as a high category, and learning experts rate comic media as a high category. Learning media are stated practical based on the results of the students' response questionnaires indicating that students can use comic media. Learning media are also declared effective based on the results of the Paired Samples T Test pretest-posttest which shows that there are significant differences between the learning outcomes at the pretest and posttest of student.
