"To teach means scarcely anything more than to show how things differ from one another in their different purposes, forms, and origins...therefore, he who differentiates well teaches well."
- John Amos Comenius (17th Century Educator)
*CGI is also a Professional Development program.
The way that teachers’ knowledge, beliefs and practices are influenced by their understanding of students’ mathematical thinking;
Instruction that influences that development;
Teachers’ knowledge and beliefs that influence their instructional practices;
Bill McCallum, University of Arizona
"Students who lack understanding of a topic may rely on procedures too heavily. Without a flexible base from which to work, they may be less likely to . . . deviate from a known procedure to find a shortcut.
