Official communications and media news in Greece about the COVID-19 pandemic very often involve a multitude of numerical concepts and mathematical relationships, which are presented in different forms and in various contexts. This paper reports selected findings of a survey among adults, which had two aims. First, to investigate their subjective…

As computational thinking (CT) gains more attention in K-16 education, problem-solving has been more emphasized as a core competency that can be found across various domains. To develop an evaluation framework that reveals students' problem-solving competency, this study examined solutions for the Bebras Computing Challenge which requires students…

Students experience challenges when understanding visual information in multimedia learning. Specifically, immersive multimedia environments, such as virtual reality increase the likelihood that students undergo distractions in which information seeking during system-paced instruction occurred. Although previous studies have reviewed various cue…

This study investigated the concept images of blind students about the polygon concept. For this purpose, four open-ended questions were asked to five blind middle school students. During the interviews, geometric shapes were presented with raised-line materials and blind students were given opportunities to construct geometric shapes with…

Chemical stoichiometry is a conceptual framework that encompasses other concepts such as the mole, writing of chemical equations in word and representative form, balancing of equations and the equilibrium concept. The underlying concepts enable students to understand relationships among entities of matter and required amounts for use when…

This study was designed to explore the effects of different geographical background contexts and signalling for information about global warming on comprehension, recall and cognitive load. Two different geographical contexts, US and Korean, were employed to frame explanations of global warming phenomena to US students. Two signalling conditions…

Instructional images are used widely in textbooks and other learning materials, but the role of learner interpretation has not been adequately explored. While previous research has demonstrated the diversity of interpretation derived from images by learners, this research has not consistently taken place in the context of authentic learning tasks.…

The study examined how student control over metacognitive prompts in a multimedia environment affects students' ability to solve mathematical problems in immediate comprehension tasks using a multimedia program and a delayed-transfer test. It also examined the effect on metacognitive discourse, mental effort, and engagement with multimedia-based…

Despite a large increase in the number of students enrolled in online courses, published research on student experiences in these environments is minimal. This article reports the narrative analysis of a series of interviews conducted with a female student at a brick-and-mortar school enrolled in a single virtual school course. Her narratives…
