Principle 1. The teacher understands
the central concepts, tools of inquiry, and structures of the discipline(s)
he or she teaches and can create learning experiences that make these aspects
of subject matter meaningful for students.
| Geometer's Sketchpad brings a different view
to learning geometry. It allows the use to discover theorems and
properties of nine-point circle and Euler line which would be impossible
without the use of some kind of manipulative for geometric figures. |
Principle 3. The teacher understands
how students differ in their approaches to learning and creates instructional
opportunities that are adapted to diverse learners.
| Some students are better at seeing things therefore
this lesson will be more adaptive to meet their needs. |
Principle 4. The teacher understands
and uses a variety of instructional strategies to encourage students' development
of critical thinking, problem solving, and performance skills.
| The use of Sketchpad connects visual justification
and empirical thinking to higher levels of geometric thinking with logical
justification in formal proof. Thus, allowing the students to discover
patterns and formulate conjectures. |
