Abstract

This study aims to describe the profile of students' problem solving status based on cognitive style. This type of research is descriptive research using a qualitative approach. Determination of research subjects using the Group Embedded Figure Test (GEFT) test developed by Witkin (1973). The results of this research are. Data analysiswas carried out with data reduction stages, data prsentasions, and conclusions/verifikation stages: 1). Problem solving with Field Independent cognitive style is at the stage of understanding the problem the subject writes what is known and asked from the question and can also explain the problem in his own sentence, at the stage of designing problem solving the subject is able to determine the appropriate plan to solve the problem, at the stage of implementing the solution plan the subject of the problem can apply a predetermined plan to solve the problem and also get the correct answer, at the stage of re-examining the subject writes the final conclusion but does not re-examine the calculations made. 2). Problem solving with Field Dependent cognitive style is at the stage of understanding the subject can determine what is known and asked in the problem, and can explain in his own sentence even though it is not much different from the question sentence, at the planning stage the subject is able to determine the appropriate plan to solve the problem. the stage of implementing the plan the subject can apply the predetermined plan to solve the problem and also get answers, at the stage of re-examining the subject writes the final conclusion but does not re-examine the calculations made.

Abstract

Tujuan penelitian ini adalah untuk memperoleh profil kemampuan menyelesaikan soal turunan siswa Madrasah Aliyah di Kota Palu berdasarkan gaya kognitif. Penelitian ini adalah penelitian deskriptif dengan pendekatan kualitatif. Subjek penelitian 4 orang siswa Madrasah Aliyah Negeri 1 Palu yaitu 2 orang siswa bergaya kognitif FI dan 2 orang siswa bergaya kognitif FD yang berkemampuan matematika berbeda. Instrumen yang digunakan adalah Tes GEFT untuk mengumpulkan data gaya kognitif siswa dan Tes untuk data kemampuan menyelesaikan soal materi turunan. Data dianalisis menggunakan teknik analisis data kualitatif. Hasil penelitian menunjukkan bahwa 1). Subjek yang bergaya kognitif FI dan FD serta berkemampuan matematika tinggi menyelesaikan soal turunan menggunakan rumus turunan fungsi pangkat berkoefisien a, rumus turunan fungsi konstan, rumus turunan penjumlahan dan pengurangan fungsi. Subjek bergaya kognitif FI dapat menggunakan rumus turunan pembagian fungsi dengan baik dan teliti sementara subjek bergaya kognitif FD juga menggunakan rumus turunan pembagian fungsi tetapi tidak teratur dan lengkap. Subjek bergaya kognitif FI menggunakan titik stasioner dan membuat ilustrasi fungsi naik dan turun dalam bentuk grafik sedangkan subjek FD hanya menyatakan dalam bentuk pertidaksamaan. 2). Subjek yang bergaya kognitif FI dan FD serta berkemampuan matematika rendah menyelesaikan soal turunan menggunakan rumus dengan tidak teratur dan tidak jelas proses penentuan suku-suku yang diturunkan. Kedua subjek menggunakan rumus turunan fungsi pangkat berkoefisien a, rumus turunan fungsi konstan dan rumus turunan penjumlahan dan pengurangan fungsi. Subjek bergaya kognitif FI dapat menggunakan konsep titik stasioner sementara subjek bergaya Kognitif FD tidak dapat menggunakan konsep titik stasioner.

Abstract

This research pupose to describe the misconceptions and the impacts about the pythagorean and circumference at Class VIII SMP GKST Imanuel Palu. This study used descriptive qualitative method. Data collection techniques using written tests. Checking the validity of the data with the triangulation technique method, which compares the results of tests and interviews. Data analysis consists of 3 phases, namely data reduction, data display and conclusion drawing. Based on data analysis and discussion, misconceptions occur in students which include: the pythagorean material: ((1) There is a wrong concept in planning problem solving which causes students to be unable to use the opposite Pythagorean concept (2) Students generalize the use of concepts that look the same but are different in meaning and use. In the circle material: (1). Implement the wrong circle area formula (2). Misunderstanding of concepts in the area of ​​the circle formula, (3). Misunderstanding in connecting concepts to problems. Misconceptions experienced by students are caused by: (1). the existence of associative thinking in which students associate or classify a concept is always the same as other concepts, (2). the existence of wrong intuition when planning problem solving, (3). there are students' preconceptions that are not in accordance with the operation of numbers in the Pythagorean formula.

Abstract

This study is a descriptive study that uses qualitative approach aims to analyze students’ concept understanding on the quadratic equation material at GPID Sumbersari Christian Junior High School in terms of field independent cognitive style. Subjects in this study consisted of 3 students cognitive style field independent. The instruments in this study are GEFT test, concept understanding questions, and interview guidelines. Research results showed: the understanding of the three subjects of field independent cognitive style have not been able to state the concept of quadratic equation correctly. In giving examples and not examples of equations, subject 1 has not been able to examples and not examples correctly while subject 2 and subject 3 were able to give axamples and not examples of quadratic equations. Subject 3 were able to give examples and non-examples of quadratic equations well. Subject 1 and subject 3 have not been able to present the equation into mathematical representations correctly, while subject 2 was able to present the quadratic equation in the form of mathematical representations well. In using procedures or operations, subject 2 was able to use procedures well while subject 1 and subject 3 were not able to use procedures well. In linking concepts, the three subjects were still not able to relate concepts well. In this case the field independent cognitive style students do not fulfill all indicators of concept understanding so that students’ understanding in understanding the concept of quadratic equations is still low.

Abstract

Based on the results of observations conducted by researchers on students of class IX SMP Negeri 14 Palu, namely working on practice questions related to exponents and there were several problems found, namely 1). Not all students understand the material on exponents 2). there are errors in solving the questions, namely in the exponent section. 3). some students can solve the questions until the middle, and 4). no students are able to finish. This study aims to analyze the errors of class IX students of SMP Negeri 14 Palu in solving exponent number problems. This type of research is descriptive research. The approach used in this study is a qualitative approach. The sample in this study was class IX Kihajar students of SMP Negeri 14 Palu consisting of 37 students, then given a test consisting of 5 questions on exponent number material and then 1 male and female student were selected who made the most mistakes. The results of this study indicate that the errors made by male students in solving exponent number problems are: (1) conceptual errors, namely students' errors in interpreting exponents. (2) principle error, students do not follow the steps that should be written in solving the problem. (3) Arithmetic operation error, students write the wrong answer from the multiplication result. (4) Fact error, namely students make mistakes in using operation symbols. The results of this study indicate that the mistakes made by female students in solving exponent number problems are: (1) Concept error, namely students' mistakes in interpreting the concept of exponents. (2) principle error, students do not write complete steps when solving the problem. (3) Arithmetic operation error, students make mistakes when subtracting, so that it has an impact on the final result. (4) Fact error, namely students make mistakes in using number operation symbols.
