This descriptive study was conducted to (1) measure anxiety levels of geology students (N=49) and earth science students (N=68) about taking these required departmental courses; (2) measure their general anxiety level; and (3) examine factors associated with student anxiety. Results (including those related to sex differences) are reported and…

Investigated methods science and nonscience majors use to make predictions about five situations involving the conservation of mechanical energy. Two findings, among others, show that subjects did not employ identifiable strategies in over 97 percent of the cases and show differences in the way majors and nonmajors worked the problems given.…

Investigated is the extent to which students' nonscientific beliefs change by comparing before and after instruction as a function of students' reasoning skill.
