The elastic rebound theory is a fundamental explanatory geoscience construct introduced in most introductory undergraduate geoscience courses. Classroom experience, supported by a recent case study of undergraduate students' model-building activities, indicates that learning this theory tends to be incomplete, in spite of instruction employing…

At present, quality earth science education in grade school is rare, increasing the importance of post-secondary courses. Observations of post-secondary geoscience indicate students often maintain errant ideas about the earth, even after direct instruction. This qualitative case study documents model-building activities of students as they…

Should instructors assume that students possess conceptual knowledge of plate tectonics when they reach a second college geoscience course? Five cohorts in a historical geology course over 5 y--a total of 149 students--completed an in-class assignment in which they drew sketches of plate boundaries with required annotations. Analysis of the…

This study investigated the relations among preservice elementary teachers' ideas about evolution, their understanding of basic science concepts and college science coursework. Forty-two percent of 240 participants did not accept the theory of human evolution, but held inconsistent ideas about related topics, such as co-existence of humans and…
