This study explored 21 elementary science teachers' experiences of and attitudes toward playing computer games, and their positions regarding using computer games in science teaching. Also, these teachers' perspectives, willingness, and relevant professional abilities of integrating educational computer games (ECGs) into their instruction were investigated. There were three stages of data collection in this study: tape-recorded pre-interviews, experiencing an ECG for science learning, and tape-recorded follow-up interviews. This study revealed that less than forty percent of the teachers had ever used computer games in their teaching. After experiencing the ECG in this study, most teachers recognized the educational essence of ECGs, and all of them were willing to integrate ECGs in their science classes. However, most of the teachers expressed poor understanding of ECGs and digital game-based learning, and recognized the significant role of specific pedagogical content knowledge and the need for computer skills.
