受測者對於加入情境照片之B版本的學習效果沒有顯著優於A版本，可能原因是加入照片之影響不顯著，未來應增加或選擇更顯著之情境照片或影片增加訓練效果，並後續再驗證。 The purpose of the study was to explore the training effects on the hazard pictograms and classifications through designing an experimental materials based on Globally Harmonized System of Classification and labeling of Chemicals (GHS). The responses of trainees from groups of different genders or ages were also investigated.
Three different versions of the training materials were designed in this study. These teaching materials were represented with different narrative and additional warning pictures; moreover, three versions all contained voice narration and taught in auto-broadcasting slide shows. There were 59 subjects in total participating in the study which were assigned into three experimental groups. All of research subjects attended the training and participated in two post-training tests, with one post-test and the other one month later. The tests included five subtests.
The result showed that from the three GHS trainings, both post-test and one-month-later tests, the scored were significantly increased. After one month from training, especially, the change of perception risk of hazard pictogram was close to "high risk perception". Moreover, after training, GHS attitude was also significantly increased. The measurement on attitude of test after a month was even higher than post-test. There were no significant effects among different training materials. Gender and age factors did not affect hazard pictogram of GHS from training, the hazardous pictograms risk perception, and the GHS attitude.
Furthermore, research result showed that the effects of added warning pictures of B version did not significantly better than the A version. The possible causes were the warning pictures added were not significant enough. In the future study, more significantly warning pictures may be added to training materials to increase training effect.
