Abstract

Mastery of mathematical literacy is essential for developing life skills in the 21st century. Mathematical literacy is even more critical in elementary schools as it forms the basis for mastery at the junior and senior high school levels. Elementary school students differ in their characteristics from students at the higher education level. They, therefore, require an appropriate learning model to improve their mathematical literacy. This research aims to develop a learning model, termed Realistic Mathematics Engineering (RMEng), that combines the Realistic Mathematics Education approach with the steps of the Engineering Design Process and determines the model’s effectiveness. The model was validated by seven experts from three universities in Indonesia and had an Aiken validity index value of 0.786, indicating that it was valid. The RMEng model contains the following steps: understanding realistic problems, solving problems in informal ways, developing formal mathematics, developing products, and drilling. Discussions and presentations can be incorporated into each of these five steps. The RMEng model was subjected to the stages of preliminary and main field testing and was revised based on the suggestions of teachers and observers. Through experimental research compared to a control group, the RMEng model was proven more effective in increasing elementary school students’ mathematical literacy at the 0.000 significance level.

Abstract

This study aims to develop geometry learning media on curved-solid objects using Ispring Suite 8 with 3D effects supported by Google SketchUp. It also aims to find the effectiveness of the media towards the basic geometry skills and the learning result of 9th-grade students of junior high school. This study is a development study which refers to Budiyono’s development model that includes four stages. These stages are the preliminary, product development, product trial on its effectiveness, dissemination and product implementation. The entire stage was imposed on three different schools in Karanganyar, one of a district in Indonesia, by using stratified cluster random sampling. Within the three schools, we took seven classes to join the effectiveness test through the assessment questionnaire and the before-after test, as well as the efficacy test after the expert's judgement using the validation sheet. The result shows that the geometry learning media is valid based on the experts' validation judgement, and also practical based on the teacher and students’ judgement in the trial of the product. The students’ basic geometry skills and learning result are improved after getting the treatment with the media. Finally, we can conclude that this media is effective and able to be used further in the junior high school level.
