This study presents an experimental method that illustrates and quantifies the Doppler-effect phenomenon. Two stages of the experimental process were carried out. First, a simplified ripple tank was used to depict the Doppler effect, and the whole experiment was recorded by a digital camera. Second, video analyses of the recorded experiment were…

Background: Within the ambit of the Fourth Industrial Revolution (4IR), the use of technology-based tools within teaching and learning is advancing rapidly at education institutions globally, including the teaching and learning of mathematics. Learners and teachers have challenges with teaching and learning fractions in mathematics. A learner's…

The study aims to explore the difference between static infographics (SIs) and animated infographics (AIs) for developing e-learning and computer skills as well as increasing achievement motivation in students enrolled in e-learning and computer skills course in the second term of 2018/2019 at the Preparatory Year Program at the University of…

We present an innovative activity that uses data about LEGO sets to help students self-discover multiple linear regressions. Students are guided to predict the price of a LEGO set posted on Amazon.com (Amazon price) using LEGO characteristics such as the number of pieces, the theme (i.e., product line), and the general size of the pieces. By…

The purpose of this mixed-methods action research study was to increase the awareness and knowledge of secondary school professionals on dyslexia, including the role of the school-based speech-language pathologist. Two research questions guiding the quantitative data collection centered on the impact of a PowerPoint dyslexia training on the…

This research deals with a possible use of history of mathematics in mathematics education. In particular, history can be a fundamental element for the introduction of the concept of integral through a problem-centred and intuitive approach. Therefore, what follows is dedicated to the teaching of mathematics in the last years of secondary schools,…

An intelligent computer-assisted language learning (ICALL) system is an application to provide users instruction and practice as they learn a second language. In order to be more effective and more widely adopted, ICALL must better align with second language acquisition (SLA) research, moving away from menu-based or fill-in-the-blank exercises and…

In this paper, we explore how a group of 10 and 11-year-old primary school children engage with a picture book about a refugee boy from Somalia. As we examine in some detail a video-recording of the children's discussion, we suggest that the children's emotional engagement with the story was pivotal to not only their making sense of the book, but…

In light of the shift towards incorporating multimodality in the curriculum, it is of interest and value to examine the extent to which multimodal literacy is assessed in national and international literacy tests. This is so as to surface any misalignment between the two and highlight gaps which curriculum planners and assessment designers can…

The main aim of the present study is to assess whether the open learner model (OLM) is capable of promoting students' active thinking by enhancing their self-regulation in online higher education learning environments. To this aim, we systematically reviewed the literature of the last three decades and found 67 articles, of which only a sample of…

Generalizability theory is a modern, powerful, and broad framework used to assess the reliability, or dependability, of measurements. While there exist classic works that explain the basic concepts and mathematical foundations of the method, there is currently a lack of resources addressing computational resources for those researchers wishing to…

Background: As access to open data is increasing, researchers gain the opportunity to build integrated datasets and to conduct more powerful statistical analyses. However, using open access data presents challenges for researchers in understanding the data. Visuals allow researchers to address these challenges by facilitating a greater…

Discerning the intent of the author of a historical document is critical as we seek to interpret it. Disciplinary literacy uses specialized skills that seek to maximize student engagement and achievement within specified subject areas. In social studies, one of these critical skills is "sourcing." Sourcing involves exploring who produced…

In recent years, an increasing number of studies have focused on learning vocabulary from audiovisual input. They have shown that learners can pick up new words incidentally when watching TV (Peters & Webb, 2018; Rodgers & Webb, 2019). Research has also shown that on-screen text (first language or foreign language subtitles) might increase…

Missing data patterns are the combinations in which the variables with missing values occur. Exploring these patterns in multivariate data can be very useful but there are few specialized tools. The current paper presents a plot that includes relevant information for visualizing these patterns. The plot is also dynamic-interactive; so, selecting…
