q2 · i? · causal · r1

Analysis of open-ended question answers (Table 2) in a quasi-experimental pretest-posttest study of 47 preservice teachers: experimental group misconceptions fell from 14 to 6, deficient knowledge from 4 to 3; control group misconceptions fell only from 10 to 9. The article reports "approximately 40%" versus "approximately 12%" success.

"The number of preservice teachers who had misconceptions about the reasons for global warming decreased from 14 to 6. The number of those with deficient information decreased from 4 to 3."

Discussion¶

Related Claims¶

• Both experimental and control preservice teachers held knowledge gaps and misconceptions about global warming before instruction, most commonly that global warming happens due to ozone layer depletion — related
• Visual-materials instruction produced a statistically significant within-group increase in global warming attitudes (d = 0.93), while traditional instruction did not (d = 0.33) — related
• When pretest scores were controlled, the posttest attitude difference between the visual-materials and traditional groups was not statistically significant, though the experimental group's adjusted mean was higher — related
• All six interviewed experimental-group preservice teachers said visual materials changed their outlook on global warming and made them follow related news more attentively — related
• Environmentally friendly behaviors increased far more in the visual-materials group (about 65%) than in the control group (about 4%) — related
• PAIR-C scaffolding shows mixed evidence for deep understanding and reduced misconceptions in emergent-phenomena instruction — related
