n Learning and Teaching Mathematics - Connecting loci with real life

The direct algebraic approach that is used in our classrooms is one of the reasons learners believe that loci is difficult to understand. It is important that the learners first understand what the term locus means and then try to visualise and draw it. After drawing the picture, the learners can try to describe the graph directly in terms of χ and γ. By doing it this way, we make loci more understandable and more enjoyable. It is often possible to determine the equation of the locus directly. Otherwise we can use analytical geometry to describe the geometric condition algebraically in terms of χ and γ. This approach gives the learners a chance to experience the power of analytical geometry.
