This study aimed to improve students’ problem-solving skills and to describe the implementation of creative problem solving (CPS) model in Mathematics Education students of the Muhammadiyah University of Makassar in its program. This research was a classroom action research which involved 33 students with two cycles (1 cycle was 4 times meeting). The cycling stage consisted of planning, action, observation, reflection. Data collection through observation, test result, and student response were analyzed by quantitative descriptive analysis technique. The research finding was: Implementation of learning model (CPS) can improve students’ problem-solving ability which can be seen from the increasing of solving ability from 63,03 (enough) to 77,72 (high). Effective learning (CPS) implementation with learning implementation indicators improved from less category to excellent category; student activeness increased from active category to highly active category, and student responses were in a very positive category. (2) Implementation of Learning Model (CPS) can be implemented through five stages: clarification of the problem; disclosure of ideas; evaluation; and implementation. Keyword: Learning Model, Creative Problem Solving (CPS), and Problem Solving Ability.
Tujuan penelitian ini untuk menganalisis dan mendeskripsikan kemampuan menyelesaikan soal high order thinking skills (HOTS) ditinjau dari kemampuan berpikir logis. Penelitian ini merupakan penelitian deskriptif dengan pendekatan kualitatif. Subjek penelitian sebanyak 27 siswa kelas XI SMAN 2 Kabupaten Kepulauan Selayar yang dipilih 1 kelas dengan teknik purposive sampling. Pengumpulan data menggunakan tes kemampuan berpikir logis, tes kemampuan menyelesaikan soal HOTS, dan wawancara. Instrumen tes diadopsi dari instrumen baku yang divalidasi ahli. Analisis data menggunakan analisis deskriptif dan hasil wawancara diolah dengan mereduksi, menyajikan, dan penarikan kesimpulan. Hasil penelitian menyimpulkan bahwa kemampuan berpikir logis berada pada kategori rendah sedangkan kemampuan menyelesaikan soal HOTS berada pada kategori sedang. Selanjutnya, aspek kemampuan berpikir logis ditemukan bahwa siswa kategori tinggi (T) mampu memenuhi kriteria level C4, C5, dan C6 sedangkan siswa kategori sedang (S) dan kategori rendah (R) hanya mampu memenuhi kriteria level C4 dan C5. Secara umum siswa masih kesulitan memenuhi level C6 dan kemampuan C6 siswa masih tergolong rendah. Kendala yang dihadapi siswa (S) dan (R) dalam memenuhi aspek C6 yaitu siswa mengalami kesulitan dan kendala dalam menerjemahkan permasalahan kedalam kalimat matematika, siswa belum mampu memberikan cara pandang terhadap suatu persoalan sehingga belum bisa mengeluarkan ide dan merancang solusi secara mandiri untuk menyelesaikan permasalahan dalam mengambil keputusan.
The purpose of this study is to determine the problem solving ability and reasoning ability of students in understanding exponential and logarithms material. The type of research in this study is qualitative research. To express this ability used a mathematical ability test instrument and conduct interviews. The subjects of this study were 30 students of class X MIPA of SMA Negeri 7 Mallawa, which were then chosen by 1 person each for low, medium, and high ability levels. The data obtained were analyzed using descriptive statistics and interviews were analyzed using the Miles and Huberman models. The results showed that the problem solving ability of students with low ability was in the students' inability to understand the problem and the lack of understanding of the concept of logarithmic concepts and exponents, for students who were capable of being there were still improper completion steps. As for students who are highly capable have been able to identified the elements present in the problem, able to understand the problem and solved the given problem. Where as the mathematical reasoning ability of students with low ability is very lacking because they are unable to complete the answers and cannot write the characteristics of logarithms and exponents, while for students with medium and high ability the reasoning ability are quite well proven by their ability to place the characteristics of logarithms and exponents correctly and they are able to used the properties of exponents and logarithms in solving problems properly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
