Abstract

Tulisan ini bertujuan mendeskripsikan pembelajaranpembagian dengan menekankan pemahaman pada konsep- konsepyang berada dalam operasi pembagian. Urutan pembelajarandilakukan dengan memperhatikan kesinambungan konsep-konsepberhitung dengan beracuan pada kontruksi pemahaman konseppembagian siswa yang berkemampuan rendah sampai tinggi. Susunanmateri dilakukan berdasarkan tipe-tipe kesalahan yang dilakukansiswa (mencoba mereduksi kesalahan yang terjadi). Serta hasilpenelitian rekontruksi pemahaman siswa yang pernah belajar operasipembagian.Materi-materi pembagian yang dapat disajikan dalam bentukkonkret sampai bentuk formal adalah semua materi pembagian baikmateri pembagian dengan bilangan bulat dengan bilangan bulat,bilangan bulat dengan bilangan pecah, bilangan pecahan denganpecahan, bilangan negatif, membagi dengan basis 10, dengan basis n,dengan basis x (pembagian dalam bentuk fungsi). Ternyata memilikikonsep yang sama hanya tingkat keabstrakannya saja yangberbeda-beda. Mengingat terbatasnya waktu dan tempat penyajian,pada tulisan ini hanya akan disajikan materi pembagian daribilangan bulat dan pecah secara lengkap dan bilangan pecah,sedangkan penyajian materi selanjutnya hanya secara garis besarnyasaja yang pada hakekatnya dilakukan berdasarkan prinsip sama.

Abstract

Abstract The problem of difficulty in mastering the function composition material occurs at Madrasah Aliyah Muslimat Nahdlatul Ulama Palangka Raya. This study aims to describe student errors in solving function composition problems. Descriptive method was used to identify the errors of 45 students of class X Natural Sciences. Data were collected with 5 essay questions and in-depth interviews. The essay questions were validated by three assessors from teachers and lecturers of Mathematics Education, who stated that the essay questions were of good quality. The research procedure was carried out through the stages of giving an essay test to all students and in-depth interviews with three students. The results showed that: first, there was a factual error, where students grammatically wrote the facts in the questions incorrectly, concluded the answers incorrectly, made the wrong arrows on the function composition diagram. Second, misconceptions occur due to misunderstanding the types of functions and the terms of the composition of functions which causes incorrect answers to solve the problem of proving the composition of functions. Operational errors occur because students do not master algebraic arithmetic operations. Errors in principle occur, where students do not understand well the definition and properties of compositional functions.

Abstract

This study aims to describe the errors and factors that cause students to make mistakes in solving trigonometry problems. This research is a descriptive research with a quantitative-qualitative approach. The data collection techniques in this study were tests and interviews. Based on the results of the study, the errors made by students were∶ (1) fact errors (68.55%), namely students did not write and incorrectly write the symbol or notation of the symbols "α" and "°" in trigonometry material, (2) concept errors (30.65%), namely students could not and incorrectly determine trigonometric comparisons and students did not understand and apply the relationship between special angles and trigonometric comparison formulas, (3) operation errors (53.23%), namely students are unable to complete root form operations correctly and incorrectly enter the value of trigonometric comparisons (4) principle errors (70.16%), namely students are wrong in applying the Pythagorean formula and cannot apply the trigonometric comparison formula. The causes of errors made by students in solving trigonometry problems are∶ (1) remembering, in the form of students' lack of ability to remember material that has been learned from simple to difficult material, (2) understanding, in the form of students' lack of ability to understand the content of previously learned material, and (3) applying, in the form of lack of ability to describe material that has been learned in new situations and involves the use of rules or principles.
