Peningkatan Kemampuan Pemecahan Masalah Matematis Siswa melalui Pembelajaran Berbasis Masalah

Abstract

ABSTRAKPenelitian ini dilatarbelakangi oleh hasil-hasil penelitian terdahulu yang menunjukkan bahwa kemampuan pemecahan masalah matematis siswa belum sesuai dengan yang diharapkan. Salah satu pembelajaran untuk meningkatkan kemampuan pemecahan masalah matematis adalah pembelajaran berbasis masalah. Tujuan penelitian ini adalah untuk mengetahui peningkatan kemampuan pemecahan masalah matematis siswa sebagai akibat dari pembelajaran berbasis masalah. Penelitian ini adalah kuasi eksperimen yang menerapkan dua pembelajaran yaitu pembelajaran berbasis masalah dan pembelajaran konvensional. Populasi dalam penelitian ini adalah siswa di salah satu SMK di Kabupaten Garut. Pengambilan sampel dilakukan secara purposive sampling, dan diperoleh dua kelas sebagai sampel penelitian. Instrumen penelitian yang digunakan adalah tes kemampuan pemecahan masalah matematis. Berdasarkan hasil analisis tersebut diperoleh kesimpulan bahwa: (1) peningkatan kemampuan pemecahan masalah matematis siswa yang mendapat pembelajaran berbasis masalah lebih baik daripada siswa yang mendapat pembelajaran konvensional, (2) Kesalahan-kesalahan yang dilakukan oleh siswa ketika mengerjakan soal-soal yang berkaitan dengan kemampuan pemecahan masalah matematis adalah kesalahan karena kecerobohan atau kurang cermat, kesalahan mentransformasikan informasi, kesalahan keterampilan proses, dan kesalahan memahami soal.ABSTRACTThis research is motivated by the results of previous studies that showed that students' mathematical problem solving ability is not as expected. One lesson to improve mathematical problem solving is based learning problems . The purpose of this study was to determine the increase in students' mathematical problem solving ability as a result of problem-based learning. This study is a quasi-experimental study that applies two problem-based learning and conventional learning. The population in this study were students in one of the vocational schools in Garut. Sampling was done by purposive sampling, and obtained two classes as the study sample. The research instrument used was a test of mathematical problem solving abilities. Based on these results we concluded that: (1) the increase in students' mathematical problem solving ability that gets problem-based learning better than students who received conventional learning, (2) mistakes made by student when working on the problems related to mathematical problem solving ability was a mistake due to carelessness or less closely, tansform fault information, error process skills, and misunderstanding question.Keywords: problem based learning, mathematical problem solving ability

Peningkatan Kemampuan Pemecahan Masalah Matematis dan Keaktifan Belajar Siswa Melalui Model Pembelajaran LAPS-Heuristik

“…Pemecahan masalah juga dapat mendorong siswa untuk melakukan evaluasi mereka sendiri terhadap hasil dan proses pembelajaran mereka (Sumartini, 2016). Sudah terlihat jelas bahwa kemampuan pemecahan masalah sangat berpengaruh pada proses meningkatkan potensi intelektual siswa, karena dalam belajar matematika kemampuan pemecahan masalah adalah bagian yang harus dimiliki setiap siswa (Setyorini, Sukiswo, & subali;Anggo, 2011).…”

“…Cocroft [1] said that mathematics needs to be taught to students because: (1) It is always used in all life, (2) All fields of study require appropriate mathematical skills, (3) Is a means of communication that is strong, brief and clear, (4) It can be used to present information in various ways, (5) Increase the ability to think logically, accuracy and awareness of the room, (6) And provide satisfaction with efforts to solve challenging problems.…”

“…How to solve problems obtained by students is the result of students' knowledge and experience related to problems that students want to find a solution. According to [6] said that problem solving is a process to overcome difficulties encountered to achieve a desired goal.…”

“…The reality in the field shows that KPMM students are still low. The low KPMM of students explained by Sumartini (2016) states that the achievement of vocational students in learning mathematics is still relatively low, especially in terms of KPMM. From the data obtained, 75% of students still have a relatively low KPMM.…”
