Tanya was used to using the word processing program Word, and she did some work for her brother Mike, who was using WordPerfect, a different word processing program. Tanya was quickly able to use WordPerfect for Windows with little difficulty, since many of the commands for it were the same as the commands for Word. Tanya's ability to use WordPerfect best illustrates:
a. cognitive development as a result of maturation.
b. learning as a result of social experience.

Question 2
Mr. Garvey is working on finding the volume of pyramids with his seventh-grade math class. His students have trouble distinguishing between the altitude of a face of the pyramid and the altitude of the pyramid itself. He then makes a pyramid out of cardboard, sticks a toothpick down the middle, and says, Now this is the altitude of the pyramid itself. They then deal effectively with the problem.
Based on this information, the best description of the stage of thinking Mr. Garvey's students are using is:
a. preoperational, since they cannot correctly perceive the difference between the two altitudes.
b. concrete operational, since they can solve the problem with concrete materials.
c. formal operational, since they are in the seventh grade, which typically makes them 12 years old.
d. formal operational, since finding volumes requires the use of symbols, which is abstract.
