Abstract

Kemampuan berpikir kritis merupakan kompetensi penting yang harus dimiliki mahasiswa, khususnya calon guru matematika. Namun, berbagai penelitian menunjukkan bahwa kemampuan berpikir kritis mahasiswa masih rendah, terutama dalam menentukan strategi pemecahan masalah. Salah satu upaya untuk meningkatkannya adalah melalui penerapan model pembelajaran yang tepat serta pengembangan perangkat pembelajaran inovatif. Penelitian ini bertujuan mengembangkan E-LKM berbasis inquiry learning yang berorientasi pada kemampuan berpikir kritis pada mata kuliah Teori Bilangan di Program Studi Pendidikan Matematika Universitas Mercu Buana Yogyakarta (UMBY), serta menguji kelayakannya dari aspek validitas, kepraktisan, dan keefektifan. Penelitian ini merupakan penelitian pengembangan dengan model ADDIE yang meliputi tahap Analysis, Design, Development, Implementation, dan Evaluation. E-LKM dikembangkan menggunakan Flip PDF Professional, PowerPoint, dan Canva. Uji validitas dilakukan oleh ahli media dan ahli materi, kepraktisan diukur melalui angket respon mahasiswa pada kelompok kecil dan besar, sedangkan keefektifan ditinjau dari respon mahasiswa dan hasil posttest. Hasil penelitian menunjukkan bahwa E-LKM yang dikembangkan valid berdasarkan penilaian para ahli, praktis berdasarkan respon mahasiswa dengan skor tertinggi pada aspek kemudahan penggunaan, serta efektif dengan tingkat ketuntasan belajar mencapai 100%, di mana seluruh mahasiswa memperoleh nilai di atas C+. Dengan demikian, E-LKM berbasis inquiry learning berorientasi pada kemampuan berpikir kritis dinyatakan valid, praktis, dan efektif serta layak digunakan sebagai perangkat pembelajaran inovatif di perguruan tinggi. Critical thinking skills are essential competencies for university students, particularly prospective mathematics teachers. However, previous studies indicate that students’ critical thinking abilities remain low, especially in determining appropriate problem-solving strategies. One way to improve these skills is through the implementation of appropriate learning models and the development of innovative learning materials. This study aims to develop an inquiry learning-based electronic student worksheet (E-LKM) oriented toward critical thinking skills in the Number Theory course at Universitas Mercu Buana Yogyakarta (UMBY) and to examine its feasibility in terms of validity, practicality, and effectiveness. This research employed a development method using the ADDIE model, consisting of Analysis, Design, Development, Implementation, and Evaluation stages. The E-LKM was developed using Flip PDF Professional, PowerPoint, and Canva. Validity was evaluated by media and material experts, practicality was measured through student response questionnaires in small and large groups, and effectiveness was assessed through student responses and posttest results. The findings indicate that the developed E-LKM is valid based on expert judgment, practical according to student responses with the highest score on ease of use, and effective with a 100% learning mastery rate, where all students achieved grades above C+. Therefore, the inquiry learning-based E-LKM oriented toward critical thinking skills is valid, practical, and effective for use as an innovative learning tool in higher education.
