Which one of the following teachers is definitely keeping in mind piaget's idea that assimilation and accommodation are both necessary for learning and cognitive development to occur?

a. mr. ames presents brand new topics every day, expecting the continual novelty to keep students interested and motivated.
b. ms. baretta makes sure that students have learned one topic very, very well before moving on to another.
c. mr. chang shows students how a new topic is similar to the things they already know, but also different in certain ways.
d. ms. doherty uses a lot of drill-and-practice exercises, encouraging students to work faster every time.

C. Mr. Chang shows students how a new topic is similar to the things they already know, but also different in certain ways.

Explanation:

Jean Piaget explained how children create knowledge from their prior experience and the surrounding environment. In his theory of cognitive development, he explained the process of assimilation and accommodation for cognitive growth. Assimilation is the process of modifying the new information using our prior knowledge and accommodation is the restructure of the prior knowledge is restructure so that new knowledge can fit in.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
