String lnvision: Conics Teaching Model
Don Hillacre
The String lnvision conics teaching model was designed as a classroom manipulative for Math 30 students, to enhance their ability to understand the physical properties of the conic sections with respect to the intersection of a plane and a cone. Use of the model in the classroom allows students to experiment with various conic scenarios and to demonstrate their understanding of the conic properties. The three-dimensional and interactive qualities of the model provide opportunity for hands-on learning and concept reinforcement that the two-dimensional and static models fail to do.
