In the present study we combined two approaches to teach seasonal changes: laboratory activities and specially designed images. To investigate the effectiveness of the teaching approaches we adopted a 2x3 experimental design: we randomly assigned 9th grade students to “laboratory” and “no laboratory” conditions while both groups received instruction under one of the three conditions: textbook images and text; teaching booklets with specially designed images and text; only text. Overall, we involved in the six experimental conditions 337 students. A draw-and-explain task and a multiple choice/true false questionnaire were used as pre and post-test evaluation. Preliminary results show a significant interaction effect of the two teaching strategies. Results will be presented in the workshop.
