Chapter 1: Educational Psychology: Understanding Learning and Teaching
** 74. Mr. Smith is discussing the question, “What would life be like for us if we were living 100 years from
now?” His students deal with the question effectively. Which stage of development is best illustrated by
the students’ ability to deal with the question effectively?
a. Sensorimotor
b. Preoperational
c. Concrete operational
d. Formal operational
** 75. You’re teaching the concept arthropod (insects, spiders, lobsters, crabs, shrimp, etc.) to your fifth graders.
Using Piaget’s work as a basis for your decision, which of the following would be the best example for
teaching the concept?
a. A lobster from a fish store
b. A movie showing a “crabber” catching crabs in a crab pot
c. A color picture of a shrimp swimming in the water
d. A picture showing insects and their body parts
** 76. Mrs. Wells is teaching her fifth graders to find the volume of rectangular solids using the formula V = l x w
x h (length times width times height). They had difficulty with the problems, and they couldn’t seem to
visualize the boxes when shown pictures of them in their textbooks. According to Piaget, which of the
following would be the best solution to this dilemma?
a. Wait until they are developmentally ready to deal with the abstraction in finding volume. (Wait and
teach it in the sixth grade.)
b. Show them an empty box, and put cubes in it until it is full to illustrate volume and the cubic
dimension.
c. “Walk them through” several problems taken from their textbooks, being certain that they are
successful at each step in the calculation.
d. Give them pictures of boxes to help them better visualize the problem.
** 77. 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.
Use the following information for items 78 and 79.
Mrs. Green teaches an eighth-grade physical science class with students of average to above-average ability. The
students are having a difficult time understanding the idea that ice melts at 32 degrees Fahrenheit and water freezes
at the same temperature. They can’t understand how a solid and a liquid can be at the same temperature when the
material is the same.
Mrs. Green explains, “Heat is required to change ice from the solid state to the liquid state. The energy is
needed to break down the orderly arrangement of the molecules in the ice, even though the molecules don‘t move
any faster.”
Her students still don‘t get it.
** 78. Which of the following would be the most likely explanation Piaget would offer for the students’ difficulty?
a. The students are not yet chronologically at the age of formal operations, and this is a formal
operational task.
b. The students’ maturation isn‘t to the point where they are ready to handle this topic.
c. The students lack the ability to understand topics as sophisticated as Mrs. Green is trying to teach.
d. The students lack the concrete experiences needed to understand the ideas involved.
