q3 · i? · causal · r2

Comparison across spring and fall 2013 with 272 traditional and 252 revised geologic time students; the new final exam question asked students to plot key events on a 4.6 in. line representing Earth's 4.6 billion year history.

"However, independent t-tests of mean scores for the Earth history question (Fig. 3) on the final exam showed that students in the revised laboratory courses scored significantly higher than those in the original laboratory course (Table VI)."
