Ms. Fodea started her first-period geometry class. Each student was to investigate a packet of geometrical forms and draw generalizations from their explorations. Students sat quietly at their desks examining the different plastic shapes, comparing them, measuring their lengths and angles, computing perimeters and surface areas, and recording their observations.
As the students work and Ms. Fodea circulates among them, from a cognitive constructivist perspective, which of the following should she most strongly emphasize?
a. Make sure that students know the names of the shapes and the formulas for finding them.
b. Encourage the students to make precise measurements of each shape.
c. Emphasize the role that numbers and quantitative understanding play in helping to understand geometry.
d. Encourage the students to individually apply existing knowledge of geometric shapes to find patterns in their observations.
Question 2
Of the following guidelines for applying information processing and the model of human memory with her students, which is Karen best demonstrating by having Jayden run back and forth across the classroom?
a. Conduct reviews to activate schemas and check perceptions.
b. Begin learning activities with attention-getting experiences.
c. Develop learners' background knowledge with high-quality representations of content.
d. Interact with students to promote cognitive activity and reduce cognitive load.
