Scientific paper
I developed a test, hereafter the Baseline Test, to measure the extent to which students meet the expectations of a college level, algebra-based, introductory physics course with regard to prior preparation in math and science. The average Baseline Test score for a sample of N=182 undergraduate students is 0.55 ± 0.18, consistent with past efforts to make similar measurements. Positive correlation is found between Baseline Test scores and average exam scores (r=0.57, p < 0.0001, N=144). Positive correlation is also found between Baseline Test scores and Force Concept Inventory gains (r=0.45, p < 0.0001, N=141). An analysis of the complete record of student responses to each of the Baseline Test questions and the multiple choice questions on exams reveals no apparent, causal relationship between prior preparation in math and science and student performance on exams. The data suggest the presence of a hidden variable.
