Abstract:Penelitian dilatar belakangi oleh rendahnya kemampuan pemecahan masalah matematika siswa dan perbedaan karakteristik siswa dalam menerima dan mengorganisasikan serta mengolah informasi dalam menyelesaikan masalah. Penelitian bertujuan untuk mengetahui bagaimana kemampuan pemecahan masalah matematika siswa ditinjau dari gaya kognitif reflektif. Jenis penelitian adalah penelitian deskriptif dengan pendekatan kualitatif dengan subjek penelitian yaitu 3 orang siswa dengan kemampuan (tinggi, sedang dan rendah) pada… Show more
“…Salah satu tujuan pembelajaran matematika yang harus dikuasai oleh peserta didik adalah kemampuan pemecahan masalah (Rismen & Devinda, 2020). Banyak konsep matematika yang sebenarnya digunakan dalam memecahkan masalah di kehidupan seharihari.…”
The purpose of this research is to obtain the validity of E-Comic based problem-solving in similarity material. This research is included in the development research with a quantitative approach using the ADDIE development paradigm, but just for three-stage: Analyze, Design, and Development. The instruments of data collection used the questionnaire validation and interview by experts. Based on the results of the validity test to media experts and material experts, it was concluded that the validity of mathematical e-comic based on problem-solving with similarity material reached a very valid with the average is 4,48 from a scale 1-5, so this e-comic media could be continued at the next ADDIE stage to fulfill practicality and effectiveness.

“…Yet, the importance of this ability has not been accompanied by findings in reality. This is revealed from the many studies that show the low problem solving abilities of students (Apriyani et al, 2019;Hadi et al, 2018;Mairing, 2017;Munawaroh & Fathani, 2019;Rismen et al, 2020;Rostika & Junita, 2017;Sapitri et al, 2019;Ali Shodikin, 2016). Cifarelli (2016) shows the important role of abductive reasoning in solving mathematical problems.…”
Background: Abductive reasoning is the process of making conjectures to explain surprising observations. Although this conjecture is not certain to be true, in solving a problem, this reasoning is very helpful to determine the best solution strategy. Objectives: The study aims to investigate whether all types of abductive reasoning lead to the formation of new schemes. Design: This research used a qualitative approach with a descriptive exploratory design. Setting and Participants: A total of 41 students of the research degree in mathematics education programme were involved in solving a task. Then, eight of them were chosen for an in-depth interview, representing the undercoded and overcoded abductive reasoning types. Data collection and analysis: The data collected were the results of the students' works and task-based interviews. Piaget's schema theory was used to analyse students' thinking processes using abductive reasoning. The analysis was carried out at all steps of problem solving, namely understanding the problem, devising a plan, carrying out the plan, and looking back. Results: Those who carried out overcoded abductive reasoning used this reasoning to determine problem solving strategies. Meanwhile, those who carried out undercoded abductive reasoning used it to determine problem solving strategies as well as to form new schemes. Conclusions: The results showed that students who did abductive reasoning did not always produce new schemes. This study also notes that the truth value of answers from the application of abductive reasoning in problem solving was open and the importance of the look back step to perform accommodation.
“…Namun, langkah problem solving Polya merupakan langkah yang terkait dan cocok dengan sebagian besar pemecahan masalah di matematika (Carson, 2007) dan direformulasikan oleh ahli lain, seperti Garofalo & Lester Jr (1985) memodifikasi menjadi langkah orientasi, organisasi, eksekusi, dan verifikasi. Hasil penelitian García, Boom, Kroesbergen, Núñez, & Rodríguez (2019) (Hidayat, Sa'dijah, & Sulandra, 2019;Mulyo, Sari, & Syarifuddin., 2019;Purnomo, Widodo, & Setiana, 2020), menggunakannya sebagai suatu model pembelajaran efektif (Lee, 2016;Mardika & Hasanah, 2019), dan mendeskripsikan kemampuan pemecahan masalah siswa (Annizar et al, 2020;Rismen, Juwita, & Devinda., 2020;Wulan & Anggarini, 2019).…”

“…Beberapa penelitian terkait pemecahan masalah geometri sudah banyak dilakukan seperti deskripsi kemampuan pemecahan masalah geometri berdasarkan perbedaan individu seperti gender, gaya kognitif, Adversity Quotient (AQ), atau kemampuan matematika siswa (Mulyo et al, 2019;Rahimah, 2019;Rismen et al, 2020;Sofyana, 2013;Yani, Ikhsan, & Marwan, 2016). Peneliti lainnya meneliti proses berpikir siswa saat memecahkan masalah geometri (Hidayat et al, 2019;Rahmatia, Wibowo, & Jannah, 2019 (Miles & Huberman, 1984).…”
Tujuan dari penelitian ini adalah untuk mendeskripsikan profil kemampuan problem solving siswa pada masalah kubus dan balok berdasarkan level berpikir Van-Hiele. Profil kemampuan problem solving merupakan gambaran umum aktivitas memperoleh solusi dari masalah matematika yang dilakukan oleh siswa dengan menggunakan pengetahuan sebelumnya yang telah dimiliki. Subjek penelitian ini adalah siswa kelas VIII MTs. Al-Islah Citrodiwangsan Lumajang. Metode pengumpulan data dilakukan dengan tes dengan think-aloud dan wawancara berbasis tugas, sehingga instrumen yang digunakan: tes level berpikir Van-Hiele, tes pemecahan masalah, dan pedoman pelaksanaan wawancara. Hasil dari penelitian ini diperoleh kemampuan pemecahan masalah siswa dengan menggunakan langkah-langkah pemecahan masalah Polya adalah siswa level-0 (recognition) sebagai kategori yang cukup, subjek dapat memahami masalah, tetapi tidak dapat menyusun rencana, melaksanakan rencana, dan melihat kembali. Kemudian, siswa level-1 (analysis) dalam kategori yang baik, subjek dapat memahami masalah, mempu menyusun rencana kemudian melaksanakannya, tetapi tidak dapat melihat kembali. Namun, siswa level-2 (order) dalam kategori sangat baik, subjek menyelesaikan masalah sesuai dengan pola dengan sangat baik. Dari keterbatasan penelitian ini, rantai bantuan dengan scaffolding belum diberikan untuk meningkatkan dan memperbaiki kemampuan pemecahan masalah siswa perlu diselidiki untuk penelitian lebih lanjut.
