Abstract

Tujuan dalam penelitian ini adalah untuk mendeskripsikan jenis kesalahan siswa SMK kelas XI dalam menyelesaikan soal pada materi fungsi. Penelitian ini merupakan penelitian deskriptif, dengan subjek 33 siswa kelas XI TOI-B SMKN 1 Cimahi yang terdiri dari 7 orang siswa perempuan dan 26 orang siswa laki-laki. Data kesalahan siswa dalam menyelesaikan persoalan materi fungsi diperoleh dari tes tertulis dan wawancara. Hasil penelitian menunjukan bahwa terdapat empat jenis kesalahan yang dilakukan oleh siswa dalam menyelesaikan soal fungsi, yaitu kesalahan konsep, kesalahan fakta, kesalahan prinsip, dan kesalahan operasi. Faktor penyebab kesalahan terjadi pada siswa karena kurangnya penguasaan materi prasyarat, tidak memeriksa kembali hasil akhir, dan masih kesulitan dalam membuat model matematika dari suatu soal.

Abstract

This research aims to know how much the mathematical disposition ability of junior high school students in West Bandung Regency contributes to mathematics learning achievement in the material of equations and one variable linear inequality. The data collection was done by giving a questionnaire and analyzing students’ achievement from daily test scores in the material of equations and one variable linear inequality. The population of this research were seventh grade students in West Bandung Regency, with the selected sample by using simple random sampling technique are 25 students of class VII-F in SMP Negeri 1 Gununghalu. Meanwhile, the disposition questionnaire was made based on following indicators; (1) self-confidence (2) persistence or perseverance (3) open thinking or perseverance (4) interest and curiosity (5) monitor and reflect (6) Respect the usefulness of mathematics. The results showed that there was a significant linear relationship between mathematical disposition and student learning achievement, with a contribution of mathematical disposition of 13.8% to student learning achievement on the material equation and one variable linear inequality, and 86.2% influenced by other variables.

Abstract

This is a qualitative descriptive research with 20 students from class X PFPT-A SMKN 1 Cimahi as subjects. The objective is to find out the types of students’ errors when completing problem material functions referring to Newman error categories and their causes. The data analysis obtained from written tests and interviews. The data validity test was carried out by data reduction, data presentation, and data retrieval. The results showed that there were 4 types of errors made by students, namely errors of understanding by 16%, transformation errors by 15%, errors of process skills by 32%, and errors in writing answers by 1%. Moreover, the students’ error caused by several matters, such as the students not get used to the form of stories, unable to interpret the problem as a whole, the lack of practice in solving non-routine problems, and in a hurry when working on the questions.
