Abstract

This study aims to analyze student errors in solving story problems based on Newman's stages and provide scaffolding to minimize errors made by students. The subjects in this study were 19 students of class VIII4 SMPN 1 Mollo Utara. The method used in this research is descriptive qualitative. Data collection techniques using observation, tests and interviews. The data analysis technique is by the Miles and Huberman model where the validity of the data is tested by technical triangulation. The results showed that the errors made by students in solving story problems based on Newman's stages were misunderstandings, transformation errors, process skills errors and notation errors which were respectively 47,37%; 5,7%; 26,31% and 21,05% of students. A form of error that students did not make at all was a reading error. The scaffolding strategy applied by the teacher to the students to overcome these errors is the strategy of explaining and reviewing the types of errors in understanding, transformation and notation as well as the strategy of explaining, reviewing, and restructuring on the types of errors in process skills. Providing scaffolding in the form of teacher assistance that is explaining, reviewing and restructuring in response to student errors can encourage most students to no longer make mistakes while some students are still wrong when solving problems after being given scaffolding but the error rate is lower than before.

Abstract

Penelitian ini bertujuan untuk mengeksplorasi penerapan konsep transformasi geometri dalam motif anyaman daun lontar masyarakat Amanuban melalui pendekatan etnomatematika. Fokus utama kajian ini adalah mengidentifikasi bentuk-bentuk transformasi seperti translasi, rotasi, refleksi, dan dilatasi yang terdapat pada motif hiasan anyaman tradisional. Metode penelitian menggunakan pendekatan kualitatif dengan teknik observasi, wawancara mendalam, dan dokumentasi. Informan utama terdiri dari para pengrajin berpengalaman yang memahami makna budaya di balik motif yang digunakan. Hasil penelitian menunjukkan bahwa transformasi geometri secara sadar atau tidak telah diterapkan dalam berbagai pola anyaman sebagai bagian dari ekspresi budaya dan estetika. Temuan ini mempertegas bahwa praktik budaya lokal dapat menjadi sumber pembelajaran matematika kontekstual yang bermakna, serta memperkaya pemahaman tentang hubungan antara budaya dan konsep matematis.

Abstract

Students’ ability to mathematical literacy is very important in their math learning process. Less ability of mathematical literacy as students’ way of thinking, argumentation, and creating is no improvement so they face difficulties in solving math problems in their learning process related to real life. The analysis of the result from students of SMP Kristen 1 Mollo Selatan shows that they are still a low inability of mathematical literacy. The effect is questions that used as the exercise are common questions and not related to real life. To solve this problem, the researcher implemented Problem Based Learning (PBL) as a teaching literacy to improve students’ mathematical literacy abilities. This study will compare two classes in which one of them treated with PBL one of the other ones was not treated with PBL. A quasi-experiment quantitative method that used in this study with nonequivalent control group design. Two classes were selected as the sample by using simple random sampling. An essay test related to students’ mathematical literacy ability was used as the instrument to collect the data. The analysis technique in this study was an independent sample t-test to the result showed that the class which was treated used the PBL method was better than the class which was not treated used the PBL method. Students’ mathematical literacy ability in the PBL class was significantly proved in the high category with the score gain 0,8
