Abstract

The understanding mathematics ability is a basic ability that is very important and must be possessed by students in learning mathematics. In fact, the ability to understand mathematics is still relatively low, especially in triangles and quadrilaterals. The purpose of this study is to produce teaching materials on triangles and quadrilaterals based on the GeoGebra-assisted discovery learning method that is valid, practical, and effective to improve students' mathematical understanding abilities. The method in this study is the ADDIE type of research & development method. The teaching materials developed in this study were student worksheets and learning videos. The subjects in this study were seventh grade junior high school students. Data processing techniques consist of analysis of the results of the validation of material experts and ICT experts, practicality analysis obtained from the results of filling out questionnaires for student responses to teaching materials, and effectiveness analysis obtained from the results of students' mathematical understanding ability tests. The results of this study are student worksheets and learning videos developed that meet the criteria of being very valid, very practical, and very effective for improving mathematical understanding skills. The developed teaching materials can be used by teachers so that students are able to easily understand the concepts in the area of triangles and quadrilaterals.

Abstract

The purpose of this study was to find out the relationship between statistical literacy and mathematical representation of students as pre-service elementary school teachers through the Collaborative Problem Solving (CPS) model. The relationship between statistical literacy and mathematical representation was analyzed by using a product-moment correlation with a sample of 35 students of Elementary School Teacher Education Study Program at one of the state universities in Ambon City. The results showed that there was a positive and strong relationship between statistical literacy and mathematical representation with a correlation value of 0.66. This relationship means that if students have good mathematical representation abilities, statistical literacy abilities are also getting better. Exploration of statistical literacy and mathematical representation abilities can be facilitated by using The CPS learning model. The CPS learning model can facilitate student learning as a structure in mathematical thinking so that statistical literacy and mathematical representation abilities of students can be explored through the transformation of ideas among students. The CPS learning model aspects were implemented in high and very high categories while the indicators were at rating-2 and rating-3.
