THE INVESTIGATION OF APPLICABILITY OF WORKSHEETS WAS DEVELOPED FOR PROJECTION UNIT IN SOLID GEOMETRY
Solid Geometry is one of the topics that students have difficulties in Geometry. In this study, worksheets about projections were developed and it was investigated the applicability of the worksheets in real class environment. Worksheets were applied in a secondary school 12th grade class which consisted of 36 students in Trabzon. Results of the study show those worksheets which required using three-dimensional dynamic geometry software such as Cabri 3D facilitate to learn the topics of Space Geometry and using dynamic geometry software in geometry class made students pleasant. Another important result is that these kinds of worksheets enhance students' interests to the lesson. Based on this study, that kind of worksheets which required using dynamic geometry software should be developed for other topics in Space Geometry.
