Abstract

Statistical literacy is strongly needed in the 21st century in reading data information, thinking critically and making decisions. The purpose of this study is to describe the statistical literacy abilities of high school students in solving contextual problems taking into account their initial statistical abilities, with the following indicators, Tier 1 (reading & explaining data), Tier 2 (analyzing, interpreting, interpreting critically, and making conclusions), Tier 3 (presenting data and predicting something). This research is a qualitative in nature, using statistical ability test, statistical literacy test, and interview guidelines to collect data. The subjects of this study consist of three female students of grade XII Senior High School, with high, medium and low initial statistical ability categories. The results of this study revealed that (1) The student with high initial statistical abilities can meet the indicators of Tier 1, Tier 2, Tier 3, so that she can be categorized at level 5 to 6 (critical-mathematics critical), (2) The student with medium ability can fulfil the Tier 1 indicator not fulfil the indicators in Tier 2 and Tier 3, so that it can be categorized at level 3 to 5 (Consistent noncritical-Critical), and (3) The students with low abilities can fulfill the indicators of Tier 1 not fulfil the indicators in Tier 2 and Tier 3, so that it can be categorized at level 1 to 3 (Idiosyncratic-Consistent Noncritical). Therefore, it is important for students and teachers to know statistical literacy skills in order to increase their understanding and ability to understand information in making decisions regarding daily problems.

Abstract

It is important for a student to be able to solve problems. This study aims to describe students’ thinking processes in solving open-ended problems with online learning reviewed from mathematical abilities. This research is descriptive in nature with a qualitative approach. The subjects of this research consist of three 8th grade students, while the research instruments that were used consist of a mathematical ability test, an open-ended problem test and interview guideline. The results of the study reveal that student with high mathematical abilities meets all indicators of thinking processes, while student with average mathematical ability at the step of understanding the problem, did not carry out of making arguments, at the step of devising a plan he did not carry out the considering thinking process, as well as did not give an argument at the step of looking back. Almost the same as these results, student with low mathematical ability did not carry out the thinking process of remembering and the process of considering, while at the step of looking back, he did not carry out the process of considering and making an argument. Based on these results, it can be concluded that mathematical ability affects a student’s thinking process.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan literasi matematis siswa SMP dengan skor tes tinggi, sedang, dan rendah dalam menyelesaikan soal matematika model PISA dengan konten change and relationship. Jenis penelitian ini adalah penelitian kualitatif. Penelitian ini dilakukan di kelas IX SMP Negeri 33 Gresik. Subjek penelitian ini sebanyak tiga siswa yang terdiri atas satu siswa dengan tingkat skor tes tinggi, satu siswa dengan tingkat skor tes sedang, dan satu siswa dengan tingkat skor rendah. Instrumen yang digunakan meliputi tes soal matematika model PISA dengan dengan konten change and relationship, pedoman wawancara, dan catatan lapangan. Teknik analisis data yang digunakan meliputi analisis data hasil tes soal matematika model PISA dengan konten change and relationship, dan analisis data wawancara. Hasil penelitian ini menunjukkan bahwa literasi matematis. Siswa dengan skor tes tinggi mampu mengidentifikasi informasi, mengubah masalah ke dalam model matematika, menggunakan strategi yang tepat, menafsirkan hasil ke dalam masalah kontekstual, dan mengevaluasi hasil dengan pengecekan langkah-langkah baik dalam konteks pribadi maupun sosial. Siswa dengan skor tes sedang dapat mengidentifikasi informasi, mengubah masalah ke dalam model matematika, menggunakan strategi yang tepat, menafsirkan hasil ke dalam konteks masalah, dan mengevaluasi hasil dengan pengecekan langkah-langkah baik pda soal dengan konteks pribadi, sedangkan pada konteks sosial siswa dengan skor tes sedang mengalami kesulitan dalam menyelesaikan soal yang diberikan serta siswa tidak dapat menafsirkan dan mengevaluasi hasil. Siswa dengan skor tes rendah mampu mengidentifikasi informasi dan mengubah masalah ke dalam model matematika, namun mengalami kesulitan dalam menggunakan strategi yang tepat, menafsirkan hasil, dan mengevaluasi langkah-langkah, sehingga siswa tidak dapat menyelesaikan soal secara lengkap baik pada konteks pribadi maupun sosial. Hasil penelitian ini memberikan informasi yang berkaitan dengan deskripsi literasi matematis siswa dalam menyelesaikan soal matematika model PISA dengan konten change and relationship. Sehingga, guru dapat merancang strategi pembelajaran yang tepat untuk meningkatkan pemahaman dan kemampuan siswa dalam menyelesaikan soal matematika yang sesuai dengan standar PISA.
