Abstract

Abstract This research aims to develop a graph theory textbook that is valid, practical and effective in improving students' mathematical representation abilities in learning graph theory in discrete mathematics courses. The method used is research and development with the Plomp model development design which consists of five stages in the form of (1) initial investigation, (2) design, (3) realization/construction, (4) tests, evaluations and revisions, (5) implementation. The subjects in this study were students who took discrete mathematics subjects, academic year 2018/2019 Mathematics education program STKIP Soe as many as two classes. Research data collection techniques in the form of observation, tests and questionnaires. The product in the form of a graph theory textbook that was developed was tested for validity based on the results of the assessment of the expert team as a validator. The practicality of the product was tested using questionnaire analysis of student and lecturer responses. Test the effectiveness of textbooks in improving the ability of mathematical representation is done through quasi-experimental research with analysis techniques using independent sample t test and normalized gain score. The results showed that the graph theory textbooks developed were valid, practical and effective in improving students' mathematical representation abilities. Keywords:discrete mathematics, mathematical representation, textbooks

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.
