Mayer (2017, 2020) proposed three major design features of computer-assisted instructions (CAI) within the Cognitive Theory of Multimedia Learning: reducing extraneous processing (i.e., excluding irrelevant content), managing essential processing (i.e., focusing on the complex but essential learning materials), and fostering generative processing…

Many online learning experiences integrate some form of dialogic interaction among instructors and learners. However, the degree to which these individuals come to a mutual understanding of their task and topic, a phenomenon called intersubjectivity, often remains a question. This systematic review of online learning research examines 48…

Despite seamless vocabulary learning studies having been implemented for about 10 years, little is known about what seamless vocabulary learning studies are, how they were conducted, what the learning outcomes were, or the issues and trends of seamless vocabulary learning. This literature review aimed at addressing these questions. Adopting…

The "Framework for K-12 Science Education" (National Research Council, 2012) outlines eight practices to represent the diverse ways scientists construct and evaluate knowledge. Engaging students in these practices is a key instructional target in the science classroom. This target, however, creates particular challenges for online…

This paper reports the development and validation of a digital application (Assessment Scale of Oral Language at School -- Decision Support System, EVALOE-DSS) for the professional development of teachers aiming to improve their students' linguistic competence. We performed a multiple case study involving seven teachers and their students from…

The pandemic in 2020 has profoundly impacted millions of people all around the world. We have experienced intense disruption in our daily lives. We have lost loved ones, jobs, motivation, and precious time that could have been used more productively. The pandemic did not distinguish between borders, race, or gender. It affected everyone but not…

Even though engineering outreach to K-12 schools initially seemed to be a simple undertaking, it proved to require complex design solutions related to a variety of issues. The purpose of this design case is to tell the story of our National Science Foundation (NSF) supported engineering outreach project, that took place between the years of…

The Adventure Learning (AL) approach to designing and implementing learning experiences has great potential for practitioners. This manuscript delineates the practical enactment of AL to support the K-12 community, teacher educators, and residential environmental science program providers in the conceptualization and delivery of their own AL…

This article presents a review of existent literature that provides insight in the effectiveness of computer learning games. Based on this research, the effectiveness of games is illustrated in detail with regard to three current perspectives on games: design characteristics of games, the process of gameplay and the reflection of specific…

Software avatars are increasingly applied to support children's collaborative storytelling because avatars may serve as a transparent shield or as embodied agents to facilitate creativity in children. However, when using avatars, it is not easy for children to practise and refine their speaking skills by narrating their stories to an audience. The…

Developing fluency and flexibility in mathematics is a key goal of upper primary schooling, however, while fluency can be developed with practice, designing activities that support the development of flexibility is more difficult. Drawing on concepts of adaptive expertise, we developed a task for a multi-touch classroom, NumberNet, that aimed to…

Three-dimensional dynamic geometry software has the power to enhance students' learning of spatial geometry. The purpose of this research is to clarify what potential using three-dimensional dynamic geometry software can offer us in terms of how to develop the spatial geometry curriculum in lower secondary schools. By focusing on the impacts the…

In this paper, we present a mobile technology-assisted seamless learning process design where students were facilitated to develop their personalized and diversified understanding in a primary school's science topic of the life cycles of various living things. A goal-based approach to experiential learning model was adopted as the pedagogical…

Educational Badges are touted as an alternative assessment that can increase learner motivation. We considered two distinct models for educational badges; merit badges and videogame achievements. To begin unpacking the relationship between badges and motivation, we conducted a study using badges within an intelligent-tutor system for teaching…

In an attempt to study the emerging questions about design of mathematical tasks that could support the solving of challenging problems, we designed two settings of interactive diagrams that share an example represented as an animation of multi-process motion but differ in their organizational functions. The interactive settings, each comprising…
