The objective of this study is to get pre-service teachers to develop an awareness of first aid knowledge and skills related to electrical shocking and safety within a scenario based animation based on a Constructivist 5E model. The sample of the study was composed of 78 (46 girls and 32 boys) pre-service classroom teachers from two faculties of education at two Turkish Universities. For the purpose of this qualitative study, an open-ended "Electrical Safety Awareness Questionnaire" was used to assess the participants' acquisition, retention and awareness levels in the beginning, at the end and five weeks after the implementation of the intervention. A one-group pretest-posttest design was adopted to measure the outcomes. Interpretative analysis was used to analyze the data. Results showed that when the subject was electricity, using an animated case scenario based on a constructivist 5E model was effective in teaching first aid knowledge and helping pre-service teachers acquire and retain technical skills about the electric shock.
