Background: Augmented reality (AR) is a widely used technology in science education today. Problem-based learning (PBL) is one of the teaching methods employed in science education for a long time. Studies where AR and PBL are used together are new and rare. PBL and AR technology are used together in the study because it is believed that…

Background: Computational thinking (CT) is regarded as an essential 21st-century skill, and attempts have been made to integrate it into other subjects. Instructional approaches to CT development and assessment in the field of computer science have attracted global attention, but the influence of CT skills on other subject areas is…

Visual representations are essential for science understanding, but many students have poor diagrammatic reasoning skills. Previous research showed that teaching high school and college students about the conventions of diagrams (COD) can improve diagrammatic reasoning. In this study, middle school science students received COD instruction…

Players of epistemic games--computer games that simulate professional practica--have been shown to develop epistemic frames: a profession's particular way of seeing and solving problems. This study examined the interactions between players and mentors in one epistemic game, Urban Science. Using a new method called epistemic network analysis, we…
