Integrated language, science and technology (ILS&T) instruction is a complex task for primary school teachers that requires professional development. Task-centered educational approaches such as the four-component instructional design (4C/ID) model are well suited for the development of complex professional skills. This article describes the application of the Ten Steps approach to the 4C/ID model in the domain of teacher education. The findings describe a blueprint for a 4C/ID-based teacher professional development program aimed at equipping in-service primary school teachers with the competences for ILS&T instruction, which can support instructional designers, teacher educators and researchers in making informed instructional design decisions. @en

This systematic literature review presents a review of the effects of integrated language arts, science and technology (ILS&T) instruction, with an inquiry- or design-based pedagogy, in elementary schools on student achievement. To this end, an overview of the characteristics of the 19 included studies and their interventions is first presented. Second, the effects of interventions in relation to the study characteristics and outcome variables were examined, by comparing the mean effect sizes. The findings demonstrate positive effects of ILS&T instruction for all reported student learning outcome variables. Third, the relation between characteristics of the intervention and effect sizes was analysed. Interventions with higher levels of integration, a short duration, and teacher professional development activities produce higher effect sizes. These findings are relevant for the design of ILS&T interventions. The analysis was challenged by a lack of detailed information in study and intervention descriptions, which prompts a call for scholars to provide more comprehensive information in their intervention studies.@en
