Abstract

Mathematics is considered as a difficult subject for some students, leading to a decrease in students’ interest and motivation in understanding mathematical concept. In the process of classroom teaching and learning, mathematics that seems complicated and makes a bad impression for some students is an obstacle for them in solving daily mathematical problems. To deal with this obstacle, a media innovation in mathematics teaching and learning is deemed necessary as a bridge for students to understand the abstract concepts of mathematical objects through the manipulation of real objects. This paper aims to present how to create and use the media of Medan Perkalian dan Pembagian Bilangan Bulat for elementary school students. This media are quite appropriate as a learning medium used to help students understand the concept of multiplication and division, especially for grade II of elementary school students. Using this medium, students are not only capable to deal with multiplication and the division of integers but also easily understand the concept of multiplication and integers division.

Abstract

STEM is a learning approach that integrates science, technology, engineering and mathematics in the problem-solving based activities. The integration of the four scientific disciplines in STEM project activities uses the Engineering Design Process (EDP) stage. This stage is a cycle in the form of repeated steps and might change until a problem-solving solution is identified. The difference of elementary school students’ characteristics and stages of cognitive development as well as the absences of a specific STEM curriculum causes teachers who are new to STEM find it difficult in implementing the existing model. Therefore, it is necessary to develop the stages of the STEM learning model in accordance with the characteristics of teachers and students. This stage was developed with the aim of making STEM easier to apply and easily connecting problems with product development from the STEM project. The variation of the STEM learning model developed includes the stages: create, identify, ideate, plan, build, and communicate. The STEM Learning Model design developed will make it easier for teachers to implement STEM in classroom learning.

Abstract

Augmented reality is one of the developing technologies and has a good potential to apply in the teaching and learning process. Augmented reality facilitates and improves the quality of teaching and learning process because of the combination of virtual objects with real environments by taking advantage of the use of technology. Augmented reality visualizes abstract concepts for understanding and the structure of an object model. A main characteristic for a medium classified as an augmented reality is combining real and virtual objects, integrated in real and virtual objects, and a real-time interaction. The use of augmented reality in teaching and learning has already been applied to many subjects, such as the concepts of space and geometry in mathematics, the human digestive system of biology, the introduction of traditional houses in social science, and the introduction of wudhu procedure in early childhood education or kindergarten (PAUD/TK) kids.

Abstract

Pascal's triangle has a variety of interesting patterns. This article discusses some of the patterns that might be found in Pascal's triangle and their proofs. In the teaching and learning process, teacher may invite students to observe these patterns, try the patterns to make generalization, make conjecture, prove the conjecture, and communicate the process to others. This procedure is appropriate with the teaching and learning process suggested in the Indonesian 2013 Curriculum.

Abstract

Mathematics teaching and learning is expected to raise 21st century skills called the 4C’s (critical thinking and problem solving, communication, collaboration, and creative and innovative). One of the activities to reach the mentioned skills is doing graph analysis. The characteristics of graph of exponential and logarithmic function is one of topics in which an analysis is needed. To analysis a graph, students need a right media. Geogebra is software that visualizes mathematics object including graphic function. This paper discusses the way how teach characteristics of graphs of exponential and logarithmic function using Geogebra.

Abstract

This study describes an alternative strategy in mathematics teaching and learning on derivative topic using derivative card-based media, which refers to constructivism view. Mathematics teaching and learning using constructivism principles will enable the students to construct their own knowledge/understanding so that their conceptual knowledge becomes more resistant. Meanwhile, derivative card media is an alternative media to help students understand the concepts of differential/derivative through games so that it emerges a meaningful learning.
