Successful use of ICT in the classroom requires thoughtful integration of technology and pedagogical processes during lesson preparation. This study investigated whether the information format of technological and pedagogical support affects pre-service teachers' technology integration in lesson plans. One group of pre-service teachers (n = 37) received support materials that presented technological, pedagogical and content information separately; another group (n = 36) received a version of these materials in which the technological and pedagogical information was integrated. Pre-service teachers used these support materials to create a technology-infused lesson plan. As expected, the pre-service teachers who received integrated support had relatively more design justifications in which technology and pedagogy were combined than their peers from the separate support group. However, this more advanced reasoning did not materialise in higher-quality lesson plans. Future research should investigate whether pre-training in the use of ICT could improve the effects of integrated support.
