A case study of the use of mobile phone cameras in science teaching and learning which was carried out in Sri Lanka is presented. The students’ and teachers’ views on the new approach made possible, by using the camera function of mobile phones, are discussed under teacher’s pedagogy, students’ participation and the use of technology. It was pointed out that the use of the camera fosters students’ active participation while helping students to understand the concepts in a more interesting and effective way. However, this demanded some additional pedagogical practices from planning the lesson to reflecting on its implementation and evaluation. Finally, further possibilities of using the camera function of mobile phones for science teaching and learning in Sri Lanka are discussed.
