Geometer’s sketchpad evaluation – “Chords of a circle”
“Chords of a circle” This lesson would be suitable for the NSW syllabus for arc and chords and to see the relationship between chord lengths and angles. The benefit of using the Geometer’s sketchpad software in this lesson is that resizing of the circle, chords and angles are all done with the movement of the mouse. It is an easy way for students to visualise the relationships without having to draw a whole heap of diagrams. A little lenghy to originally set up but it wouldn’t be a problem if student were familiar with the program. Would be easier if students used a printed version to follow to set up the sketch. A big tick for visual learners.
How could the lesson be improved?
Are the instructions for the lesson clear?
