Prior to instruction, students’ knowledge consisted
mainly of causes of global warming and results of the
global warming phenomenon. They did not fully understand
the scientific interactions and underlying principles
that describe how the greenhouse effect and global
warming occurs. In this study, in order for students to
receive credit as having an integrated understanding of a
target concept or phenomenon, their responses must have
correct, interconnected ideas. For example, students could
generate responses explaining the greenhouse effect by
mentioning all of the individual components required for a
correct response (solar energy, infrared energy, greenhouse
gases) but have incorrect links among the components
(solar energy (rather than infrared energy) is trapped by
greenhouse gases).
