Abstract

Abstract: The background of this research is the low outcomes study of mathematical  of students class XI MAN 3 Pekanbaru. The purposes of this research are (1) to describe the difference of mathematical outcomes study of students who study through discovery learning (DL) model with student who study through conventional learning with scientific approaching; (2) to describe the improvment of mathematical outcomes study of students who study through discovery learning (DL) model with students who study through conventional learning with scientific approaching. This research is an experimental research (quasi experiment) with The Nonequivalent Pretest-Posttest Control Group Design. The population of this research is all students of class XI MAN 3 Pekanbaru. The sample of this research consits of two classes, class XI MIA2 as experiment class and XI MIA1 as control class. The research instruments are mathematical prior knowledge test and matehmatical outcomes study test. Mathematical prior knowledge test score were used to select the sample of this research. Data were analysed by using Independent sample t-test preceded by normality test and homogenity of variances test. The result showed that the difference of mathematical and the improvement of mathematical outcomes study of students who study through DL model is higher than student who study through conventional learning with scientific approaching.  Key Words: Discovery Learning, Mathematical Outcomes Study

Abstract

Kebanyakan siswa SMA mengalami kesulitan dalam menyelesaikan soal matematika sehingga menyebabkan siswa melakukan kesalahan-kesalahan dalam penyelesaian soal. Tujuan penelitian ini untuk menganalisis kesalahan-kesalahan yang dilakukan siswa dalam mengerjakan soal pada materi matriks. Jenis penelitian ini adalah penelitian deskriptif kualitatif. Instrumen pada penelitian ini adalah instrumen tes. Subjek penelitian yaitu 30 siswa XI MIA 1 SMAN 15 Pekanbaru. Hasil analisis kesalahan dalam penelitian ini menunjukkan bahwa siswa melakukan kesalahan dalam menyelesaikan soal matematika berupa kesalahan fakta, kesalahan konsep, kesalahan prinsip dan kesalahan operasi. Persentase kesalahan yang dilakukan siswa pada kesalahan fakta sebesar 18,3%, persentase pada kesalahan konsep sebesar 26,1%, persentasi pada kesalahan prinsip sebesar 25,6%, dan persentase pada kesalahan operasi sebesar 25%. Jenis kesalahan yang paling banyak dilakukan oleh siswa adalah kesalahan konsep. Kesalahan konsep terjadi disebabkan siswa belum memahami konsep materi sehingga menyebabkan siswa kesulitan dalam menyelesaikan soal matematika. Most high school students have difficulty in solving math problems, causing students to make mistakes in solving problems. This study aimed to analyze students' mistakes in working on the problem in the matrix material. This type of research is descriptive qualitative research. The instruments in this study are test instruments. The research subjects were 30 students of XI MIA 1 SMAN 15 Pekanbaru. The error analysis results showed that students made mistakes in solving math problems in factual errors, concept errors, principle errors, and operating errors. Students' percentage of errors on factual errors was 18.3%, the percentage on conceptual error was 26.1%, the percentage on principle error was 25.6%, and the percentage on operating errors was 25%. The most common type of mistake made by students is a conceptual error. The concept error occurs because the student does not understand the material's concept, causing students difficulty in solving math problems.
