Meaningful geometry
Sunday, August 29th, 2010The way we teach and learn geometry has to change for it to have any use beyond merely passing exams.
The study of geometry is important, as it is recognised as a basic skill in mathematics – for several reasons.
Geometric models are frequently used to help students understand basic mathematical concepts. The number line, for example, is helpful to illustrate various number concepts and operations.
Geometry is a foundation for study in such fields as physics, chemistry, biology, architecture, engineering, geology and astronomy.
Geometric skills are also essential in art, design, graphics, animation, as well as in various aspects of construction work.
It has important applications to real-life problems.
Many practical experiences involve problem-solving situations that require an understanding of geometric concepts and skills, such as making frames, planning a garden and arranging a living room.
In addition, Geometric concepts, such as points, line segments, curves and grids, are necessary for basic map reading skills.
Geometry allows development of spatial visualisation which is an extremely important skill for success in mathematics and the sciences.
It helps students to understand and appreciate the world they live in.
Recognition of geometry as a basic skill in mathematics has resulted in an increased emphasis on geometry in the revised mathematics curriculum by the Education Ministry.
Geometric concepts of two- and three-dimensional shapes are formally introduced as early as Year One.
Teacher-centred instructions are sadly, still being practised in a typical geometry lessons in our country.
