Abstract

Penelitian ini bertujuan untuk memperoleh perangkat pembelajaran berbasis discovery learning berbantuan Microsoft Excel yang efektif dalam meningkattkan kemampuan pemecahan masalah statistika (KPMS)  dan soft skills siswa SMP. Kriteria efektif bersandar pada teori intervensi pembelajaran yang meliputi adanya peningkatan capaian hasil belajar setelah intervensi, adanya respon positif siswa dan guru terhadap perangkat pembelajaran yang dikembangkan, keterlibatan (engagement) siswa yang tinggi dalam pembelajaran,  serta diperoleh lebih dari 65% siswa mencapai skor 65 dari skala 100 dalam tes KPMS. Peningkatan KPMS diselidiki melalui indeks gain ternormalisasi. Peningkatan soft skills dideskripsikan dengan bersandar pada statistik deskriptik. Penelitian ini menghasilkan perangkat pembelajaran yang memiliki karakteristik efektif dalam meningkatkan KPMS dan soft skills siswa SMP sehingga siap untuk disebarluaskan. Disarankan agar guru lebih diberi kesempatan untuk mengimplementasikan perangkat pembelajaran yang dikembangkan sesuai dengan tujuan pembelajaran matematika sehingga dapat diharapkan siswa memperoleh kemampuan pemecahan masalah dan soft skills yang lebih tinggi lagi.

This study aims to obtain discovery learning-based learning tools supported by Microsoft Excel that are effective in increasing statistical problem solving abilities (KPMS) and soft skills of junior high school students. Effective criteria rely on the theory of learning interventions which include an increase in learning outcomes after the intervention, positive student and teacher responses to the learning tools developed, high student engagement in learning, and obtained more than 65% of students achieving a score of 65 from a scale of 100 in the KPMS test. The increase in KPMS is investigated through a normalized gain index. Improved soft skills are described by relying on descriptive statistics. This research produces learning tools that have effective characteristics in improving problem solving skills and soft skills of junior high school students so that they are ready to be disseminated. It is recommended that teachers be given more opportunities to implement learning tools that are developed in accordance with the learning objectives of mathematics so that students can expect to get higher problem solving skills and soft skills.
