Geometric Idea

Geometric idea are vital: we live in a three-dimensional world. Yet, for many children, in truction in geometry in the elementary school revolves around only two points: recognition of hape and development of vocabulary. Re earch provide some evidence on how these points are taught but also indicate other ideas that can be developed.

Theoretical Developments

As is well known, analysis of two surfaces in mesh plays a fundamental role in gear theory. In the past, special coordinate systems, vector algebra, or screw theory was used to analyze the kinematics of meshing. The approach here instead relies on geometric algebra, an extension of conventional vector algebra. The elegance of geometric algebra for theoretical developments is demonstrated by examining the so-called “equation of meshing,” which requires that the relative velocity of two bodies at a point of contact be perpendicular to the common surface normal vector. With surprisingly little effort, several alternative forms of the equation of meshing are generated and, subsequently, interpreted geometrically. Via straightforward algebraic manipulations, the results of screw theory and vector algebra are unified. Due to the simplicity with which complex geometric concepts are expressed and manipulated, the effort required to grasp the general three-dimensional meshing of surfaces is minimized.

School Mathematics Curriculum

What is the most neglected area of the elementary school mathematics curriculum? The answer, probably, is geometry. Too many people think of geometry as a formal structure, like the course they had in high school. As a result. they do not see its relevance to the elementary school mathematics curriculum. Activities that introduce children to geometric concepts provide experiences that help children develop and reinforce spatial perceptions.

Different Levels

Geometric concepts and skills that are appropriate for elementary school pupils include comparing figures with respect to likenesses and differences, comparing and seriating figures with respect to size, classifying figures, making measurements, and performing informal activities related to congruence and line symmetry. AJI of these concepts and skills can be developed through the use of geometric blocks. A large set, which can serve to develop many ideas presented in the elementary school grades, is shown in figure 1. Various subgroups of these shapes can be used as the basis of structuring appropriate activities on different levels.

First Interview

Young learners can be defined as children in age ranging from five or six years old who are attending elementary school to twelve years old.  In this research the researcher chose to teach vocabulary in TK (kindergarten) Aisyiyah Dolopo. The reason for choosing to teach vocabulary is because vocabulary is one of the important elements in language. The researcher focuses on teaching vocabulary words to the young learners. The researcher used pop up slide book to improve students’ vocabulary. The pop up slide book is a book which shows three dimensional pictures when the pull or trigger is pulled. The name pop up slide book is originated from the term “Slide” which means “to move smoothly along a surface”. The name slide was added by the researcher as the new variant of pop up book. The method for this research was Classroom Action Research which took two cycles. This research method was conducted to know the problems inside the classroom thus the solution can be found. The goal of this research is to make children learn English through pop up slide book. The instruments used in this research were observation, interview and test. The research results based on the implementation of popup animal slide media in TK Aisyiyah Dolopo Madiun showed that in cycle 1 up to cycle 2 the implementation of pop up slide book was able to improve students’ score. In the first cycle many students achieved score 70 and in the second observation their score were above 80. The highest score was 100 for the test in cycle 2. The interview result showed that 100% of the students liked the pop up slide book with the animal poster. In the first interview cycle, 87% of students were afraid to learn English but in the second interview cycle, 100% of students could speak English comfortably without hesitation. Moreover from the observation in first cycle only 46% students who were excited to learn with pop up book, but in the second cycle 90% of students were excited to learn English during lesson using pop up slide book. It means that pop up Slide Book as teaching media could successfully improve students’ vocabulary. Keywords: Kindergarten, Pop Up Slide Book, Vocabulary

One of the efforts in facilitating the teacher to teach the material concretely, then the learning of mathematics on three dimensional geometri can be done using the help of a medium of learning. Along with the development of technology today, many applications in the world of technology that can be useful for learning activities. One of the learning media that can help the teacher in facilitating Visualization Three Dimensional geometry is Augmented Reality. In addition, through mathematics learning using Augmented Reality media in Three Dimensional geometry is expected to present interactive math learning. This research produces instructional media using Augmented Reality based on Android for Three Dimensional geometry material in grade 5 students of Elementary School. Development of learning media Augmented Reality using Kemp and Dayton model, there are two components, namely multimedia technology components and components of mathematics subjects. Components of multimedia technology contained in the program that is text, sound, images, and animation, while the components of mathematics subject’s ie content material and exercise questions. The materials contained in the program are: (1) the cube, (2) limas, (3) the cone and (4) the tube.

Geometry has gained an accepted place in the mathematics curriculum of the elementary school. Elementary teachers have found that their pupils enjoy using compasses to construct designs and mathematical figures. Some teachers, who have tried the construction of three-dimensional solids, have found the pasting technique difficult for young fingers when conventional patterns were used. Here is a set of patterns designed to make the pasting problem easy enough so that third-grade students can succeed with the simpler solids. Teachers have been most enthusiastic about their pupils' delight and success in using them.

From an analysis of sixty-four research studies at the elementary school level, Parham (1983) reported a decided difference in the achievement scores of students who had used manipulative materials and those who had not. Those who used manipulative materials scored at approximately the eighty-fifth percentile; those not using manipulative materials scored at the fiftieth percentile. This finding is clearly in agreement with an earlier review by Suydam and Higgins (1977), a major finding of which was that lessons using manipulative materials have a higher probability of producing greater mathematics achievement than do lessons in which such materials are not used.
