Exploring Environmental Issues: Places We Live
The Project Learning Tree curriculum Exploring Environmental Issues: Places We Live was evaluated using a quasi-experimental research design that consisted of pre/post inter vention assessments measuring differences in self-assessed content knowledge, researcher assessed content knowledge, and attitudes. Treatment groups consisted of two randomly assigned groups, one group completed 3-lessons and the other group completed 6-lessons. Analysis indicated the 6-lesson treatment group demonstrated significant gains in all three categories, while the 3-lesson group exhibited significant gains in self-assessed content knowledge. The results suggest that the curriculum is valuable in delivering placebased educational content.
