Some lecturers need suitable learning media and strategies in the learning process so that learning is effective. Previously, lecturers only used book media, handouts, and whiteboards as media, and only certain materials used media. It is also known that the obstacles in using media because there are still many lecturers who do not have the…

Spatial thinking has roles to facilitate learners to remember, understand, reason, and communicate objects and the connections among objects that are represented in space. This research aims to analyze the spatial thinking process of students in constructing new knowledge seen from the field-independent cognitive style learners based on…

It might be said that for most occupations there is now less of a need for mathematics than there was say fifty years ago. But, the author argues, geometry, probability, and statistics constitute essential knowledge for everyone. Maybe not the geometry of Euclid, but certainly geometrical ways of thinking that might enable us to describe the world…

Educators are continuously looking at innovative ways to teaching and working with students of all ages. The tools used range from the simplest technologies, such as chalk and pencils, to the high-tech tools involving computers and information systems. The best tools and strategies often invoke the use of the old and new or the old in a new way.…

It is widely accepted that learning becomes more enduring and deeper if geometric concepts are presented in various orientations and dimensions in textbooks. The purpose of this study was to examine how geometric concepts are presented in the Turkish elementary mathematics curriculum and the textbooks in terms of sizes and orientations. For this…

In this article, the author describes the Lutterloh method of making dress patterns, which was developed in Germany in the 1930s. The underlying principle involves the modification of basic designs and it is claimed that it provides better fits for women of different sizes and shapes than do other commercially available patterns. The method is…

The mathematics curriculum should be imbedded into the cultural environment of the student. Discussed is the mathematical educational potential of decorative motif. (PK)

Worksheets for duplication are provided for this activity designed for students in grades 6-10. The objective of the activity is to have students discover generalizations about the patterns formed. (MK)

Discusses the use of flexible straws for teaching properties of figures and families of shapes. Describes a way to make various two- or three-dimensional geometric shapes. Lists eight advantages of the method. (YP)

Describes the stages of a process of reflective thinking. Investigates how geometrical models can be used in learning and teaching mathematics in connection with the process. Identifies two models for children of age four to eight: constant path in the space of shapes and continuous path of varied polygonal shapes. (Author/YP)

Uses pentominoes to examine the concepts of congruence, similarity, transformations, tessellations, networks, perimeter, area, and volume in a problem-solving, cooperative learning environment. Discusses the construction of three-dimensional pentominoes. (YP)

A problem sometimes called Moser's circle problem where a circular region has to be partitioned with chords without any three chords intersecting at one point, is discussed. It is shown that Moser's circle problem makes the students to use a variety of mathematical tools to find correct solutions to problems and gives an opportunity to think about…

Using the seasons in the science classroom increases student observation skills as they focus on subtle differences such as shades of color and differences in structures. In this article, the author presents a variety of activities that can help students identify and demonstrate patterns and changes in leaf or plant development. The ability to…

Provides four activities asking students to observe and classify star patterns and to identify polygons and continuous paths while observing similarities and differences. Presents the objectives, directions, extensions, answers, references, and worksheet for each activity. (YP)

The production and application of images based on fractal geometry are described. Discussed are fractal language groups, fractal image coding, and fractal dialects. Implications for these applications of geometry to mathematics education are suggested. (CW)
