Abstract

Problem solving skills are a fundamental part of physics learning that must be possessed by students in facing challenges and problems that involve critical thinking, logical, systematic and able to make the right decisions. In fact, the availability of instruments to measure these skills is still limited. Based on that, the purpose of this research is to develop a test instrument based on problem solving skills based on Heller's stages on dynamic fluid material that meets the criteria for good instrument feasibility. This type of research is development research (Research and Development / R&D) with a 4D model consisting of 4 stages, namely define, design, develop and disseminate. The subjects of this study were XI grade high school students totaling 36 people for product testing. The results showed that the average value of content validity testing was 93.53% with very valid criteria, while the results of item validation in small and large groups showed that all ten test instruments were categorized as valid. In terms of reliability, the small group obtained a value of 0.84 which is classified as very high reliability and in the large group obtained a value of 0.78 which is classified as high reliability. The results of the student response test obtained a positive response in the small group of 81.00% with a good category and in the large group of 81.32% with a very good category. Based on the results of the study, it is concluded that the dynamic fluid material problem solving test instrument developed as many as 10 questions has met the eligibility criteria of the test instrument including validity and reliability so that it can then be used as a training medium and a measuring tool for problem solving skills.

Abstract

Literasi dan numerasi termasuk kemampuan esensial dan mendasar dengan berfokus pada kemampuan berpikir logis-sistematis, bernalar dan kemampuan untuk melakukan pengolahan data dengan cermat dan tepat. Faktanya kemampuan siswa belum digali dan dikembangkan secara maksimal pada diri siswa, maka tujuan penelitian ini untuk mengembangkan instrumen tes literasi dan numerasi dalam konteks sosial dan budaya pada materi mekanika yang memenuhi kualitas kelayakan tes yang baik meliputi validitas, reliabilitas, tingkat kesukaran, daya pembeda dan respon siswa. Jenis penelitian yang digunakan adalah R&D menggunakan model pengembangan 4D yang mencakup tahap pendefinisian, perancaangan, pengembangan dan penyebaran. Subjek penelitian yaitu siswa Fase F kelas XI-1, XI-2 dan XI-3  terdiri dari 90 orang. Berdasarkan uji kelompok besar diperoleh sebanyak 30 butir soal tergolong dalam kategori valid dan layak. Reliabilitas tes berada pada kategori tinggi dengan nilai yang menunjukkan rentang yang memadai. Tingkat kesukaran soal berada pada kategori sedang, sementara daya pembeda soal termasuk dalam kategori cukup. Respon peserta didik terhadap tes menunjukkan hasil yang positif. Penelitian ini menunjukkan bahwa instrumen tes yang dikembangkan layak dan efektif untuk mengukur kemampuan literasi dan numerasi siswa pada materi mekanika.
