Information literacy and information technology (IT) skills have become increasingly important in today's knowledge society. Many studies have shown that students from primary school to postgraduate lack crucial information literacy and IT skills, hence there is a need for an effective pedagogical approach that will develop these skills. This study investigated the effect of combining a collaborative teaching approach with inquiry project-based learning (PjBL) on the development of primary students' information literacy and IT skills. Students in a Hong Kong primary school completed two inquiry-based group projects. A collaborative teaching approach involving three teachers in different subject areas (general studies, Chinese, and IT) and the school librarian was adopted in guiding students through the two projects. Results indicate that this program had a positive impact of on the development of different dimensions of the students' information literacy and IT skills.
