This study investigated the effects of instructor presence in instructional videos on learning and learners' emotional engagement. Sixty-six learners of English as a foreign language (EFL) at a Turkish university watched an English instructional video with either high-level instructor presence (whiteboard), low-level instructor presence…

This study investigated the effects of four subtitle modes on the listening comprehension of TED (Technology, Entertainment, Design) talks and academic vocabulary learning of intermediate (non-English major) and advanced (English major) English as foreign language (EFL) learners. A total of 272 Chinese college sophomore students were randomly…

The Hertzsprung-Russell diagram (HRD) is a fundamental representation in stellar physics. It contains information about key properties of stars and allows inferences about stellar evolution. The use of the HRD is an important disciplinary activity in astrophysics. For example, it is particularly important to have a graphical understanding of the…

This paper addresses the subject of the semiosis process in the transactions between teachers and students about the knowledge at stake in science education. We present a conceptualisation of these transactions as a joint action between students and teachers. This conceptualisation enables us to understand the semiosis process as it unfolds during…

Learning management systems (LMSs) are ubiquitous in higher education, yet few studies have examined changes in student engagement online with year level. Using data mining of LMSs, we examined the frequency and timing with which first, second, and third year science students accessed the various LMS resources. We compared online access with both…

Teacher competence is the spearhead of educational success in vocational schools. This study aims to analyze the difficulties experienced by Vocational High School (VHS) teachers in implementing learning, analyze the difficulties faced by language subject teachers in adjusting to the concentration of expertise in VHS, and formulate the concept of…

This study aims to explore preservice teachers' opinions about their instructors' use of PowerPoint slides during classes. To this end, 10 preservice teachers were selected through convenience sampling and semi-structured interviews were then conducted. The interviews were held one-by-one and audio recorded after having received permission from…

This paper challenges a static view of the multimedia presentation as merely a final product for grading, and discusses how to elicit evidence-based understandings about student learning from such a presentation. We present a micro-ethnographic study investigating students' learning outcomes and task interpretations from multimedia presentations.…

Although at present there are academic strategies for scientific dissemination, it is still a challenge for the general population to access quality information that is reliable, easy to understand and motivational towards science. This article proposes an image-based educational scientific dissemination tool with the goal of bringing children…

In this study, integration, or students' connection formation across texts, was examined across two tasks: when undergraduates were asked to complete a writing assignment and a novel, diagram construction task. While the writing assignment asked students to compose an argument based on multiple texts, the diagram construction task asked students…

Introduction: This article describes the development and initial assessment of a set of tactile crayons that can produce different textured lines and areas on standard paper. Method: An assessment of the need for tactile crayons was performed through the use of surveys and focus groups from which a set of six tactile crayons was developed.…

Purpose: We review two recent neuroanatomical studies of children who stutter (CWS), one that examines white matter integrity and the other that focuses on cortical gray matter morphology. In both studies, we sought to examine differences between children whose stuttering persists ("persistent"), children who recovered from stuttering…

The author began thinking about 3-D printing in 2014 when she learned that the Mississippi Library Commission would loan school libraries a printer for programming. At the time, she was a brand new school librarian who had recently transitioned from being an English teacher, so she was learning about the maker movement in libraries and all the…

Comparing groups is a fundamental activity in statistics since it includes many basic concepts like center, variability, and representation and can pave the way to inferential statistics. Preliminary work involving group comparisons can be undertaken at an early age, e.g., at primary school using proto-concepts like modal clumps, precursor…

Sensory processing difficulties affect the development of sensorimotor skills in individuals with autism spectrum disorder (ASD). However, the effect of sensory information on postural control is unclear in the ASD adult population. The present study examined the effect of visual information on postural control as well as the attentional demands…
