Abstract

Statistical habits of mind (SHOM) is a habit of mind needed to understand, analyze, and interpret data effectively. This research aims to develop an instrument in the affective aspect of measuring SHOM that is valid and reliable. The results showed that the SHOM instrument developed consisted of five faktorons, namely 1) Context of Data, 2) Intuition, 3) Inquiry, 4) Skeptical and Careful, and 5) Thinking Beyond the Textbook. Based on the factor analysis results, it was found that the SHOM instrument is content-valid and reliable but not yet construct-valid. This is indicated by the number of factors formed (13 factors) does not match the number of factors planned in the preparation of the instrument (5 factors), and there are 6 items that have insufficient factor loading values.

Abstract

This study aims to describe the level of tendency and causes of students’ errors in solving mathematic story problems. Error analysis was carried out based on the Polya's procedure reviewed from the students' learning styles. This type of research is descriptive qualitative. The sampling technique used purposive sampling and consideration from the mathematics teacher so that class VII H of SMP Negeri 13 Mataram was obtained as the research subject. The sample used was 29 students. Data collection techniques using learning style questionnaires, test questions, and interviews. Data analysis techniques are data collection, data reduction, data presentation, and conclusion drawing. Based on the results of data analysis obtained from test results and interviews, it can be concluded that, students of visual learning styles tend to make mistakes at the plans implementing stage with an error rate of 63% including in the high category and the recheck stage with an error rate of 86% including in the very high category. Students of auditorial learning styles tend to make mistakes at the recheck stage with an error rate of 58% including in the medium category. Students of kinesthetic learning styles tend to make mistakes at the recheck stage with an error rate of 44% including in the low category. The causes of these errors are because 1) students are less to understand the problem, 2) less careful in doing calculations, 3) not used to writing conclusions because students used the results from the previous stage as conclusions.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan kemampuan numerasi pada konten geometri dan pengukuran ditinjau dari  gaya kognitif. Penelitian ini merupakan penelitian kualitatif dengan jenis penelitian deskriptif. Subjek penelitian adalah siswa kelas IX  SMP Negeri 13 Mataram yang berjumlah 31 siswa, terdiri dari 3 siswa bergaya kognitif fast-accurate, 11 siswa bergaya kognitif reflektif, 12 siswa bergaya kognitif impulsif dan 4 siswa bergaya kognitif slow-inaccurate.Teknik pemilihan subjek dilakukan dengan teknik purposive sampling. Instrumen penelitian yang digunakan, yaitu i) tes MFFT (Matching Familiar Figure Test) untuk penentuan gaya kognitif, ii) tes kemampuan numerasi dengan 5 bentuk soal terdiri dari pilihan ganda, pilihan ganda kompleks, menjodohkan, isian singkat dan uraian, dan iii) pedoman wawancara. Analisis dilakukan berdasarkan tiga indikator kemampuan numerasi, yaitu (1) menggunakan berbagai macam angka atau simbol terkait matematika dasar, (2) menganalisis informasi yang ditampilkan dalam berbagai bentuk (grafik, tabel, bagan, diagram, gambar dan lain sebagainya, (3) menafsirkan hasil analisis permasalahan untuk memprediksi dan mengambil keputusan. Hasil penelitian menunjukkan bahwa a) siswa fast-accurate dan reflektif mampu memenuhi seluruh indikator kemampuan numerasi, walaupun siswa reflektif membutuhkan lebih banyak waktu; b) siswa dengan gaya kognitif impulsif mampu memenuhi dua indikator kemampuan numerasi yaitu indikator (1) dan (2) karena belum maksimal dalam menggunakan informasi yang diperoleh; c) siswa dengan gaya kognitif slow-inaccurate hanya dapat memenuhi satu indikator (1) kemampuan numerasi karena belum memahami soal AKM numerasi. Oleh karena itu dapat disimpulkan siswa slow-inaccurate belum mampu menyelesaikan soal konten geometri dan pengukuran.

Abstract

This study aimed to knowing and describe students' mathematical representation skills in solving relational and function problems for class VIII in academic year 2021/2022. The research method used was descriptive research with a qualitative approach. The instruments used were mathematical representation ability tests and interview. The research subjects were students VIII C with 30 students who were given a mathematical representation ability test grouped into high, medium, and low categories based on their mathematical ability. From each category, 2 students were selected to be interviewed further. In general, from the test results, students with high mathematical representation abilities have been able to achieve indicators of mathematical representation abilities with an achievement percentage of 82.63% which is very good. Students with moderate mathematical representation skills with an achievement percentage of 51.26%, which is sufficient. and students with low mathematical representation skills with an achievement percentage of 25.95%, which is less. From the results of interviews, students with high mathematical mathematical representation abilities were able to explain the answers to the test results very well. Students with moderate mathematical representation skills are quite able to explain their answers well. Students with low mathematical representation ability are able to explain the answer but the explanation given is less detailed.

Abstract

The purpose of the research is to identify the conceptual and procedural error of eleventh grade students in solving problems in the Applications of Derivatives of Algebraic Functions based on Cognitive Style. The subjects of this research are eleventh grade students of SMA Negeri 1 Gunungsari. The four selected subjects consist of two field independent students and two field dependent students. This research is included in the type of descriptive qualitative research. Data collection techniques were carried out in three stages, namely the GEFT test, a written test about the description of Mathematics for the application of Algebraic Function Derivatives, and interviews. The result of this study shows that the field independent students committed one conceptual error and four procedural errors with different indicators. Meanwhile the field dependent students committed three conceptual errors and three procedural errors with different indicators. The differences between the field independent and field dependent students error are be able to know based on the error type. The field independent students tend to make procedural errors. Meanwhile the field dependent students tend to make conceptual errors.

Abstract

This research aims to describe the errors made by students based on their Adversity Quotient (AQ) while solving story problems in statistics. This study is qualitative in nature with a descriptive approach. The subjects of this research are 25 students from class VIII A at SMP Negeri 1 Kediri. The instruments used include an AQ questionnaire, a written test on statistics, and an interview guideline. Based on the research findings, students categorized as AQ quitters and campers mostly made similar errors, including transformation errors, process skill errors, and encoding errors, however, quitters exhibited a higher error rate. Meanwhile, students with AQ climber types primarily made encoding errors. Transformation errors occurred because students did not understand the problems, were unsure how to convert the information from the questions into mathematical forms, and lacked knowledge of the formulas needed to solve the problems. Process skill errors were attributed to students' lack of understanding of the problems, insufficient grasp of the material concepts, and unawareness of the steps required to solve the questions. Encoding errors were caused by mistakes made in previous stages, students' lack of attention to detail, and rushing to write the final answers on the answer sheets.
