Inquiry and traditional lab students did not perform significantly differently on the
pre-test for the science literacy assessment. ANCOVA results showed that students' science
literacy assessment (SLA) post-test scores differed significantly depending on which type of
lab instruction they received (F(1, 383) =12.21, N= 386, p>0.0005). Students in the inquiry
labs showed an improvement of 4% in total correct responses while students in the
traditional lab showed no significant difference from the pre-test (Figure 1).
