The Effect That Screen Size has on Video-Based M-Learning.

Abstract

This paper focuses on using m-learning to teach university students. It reports on an empirical investigation that studied the effect that screensize has on video-based m-learning. The results suggest that screen sizes typical of a PDA device may facilitate more effective learning, in comparison to screen sizes typical of a mobile telephone. The implications of this finding for the design of m-learning environments are discussed.

Perceived usability evaluation of Microsoft Teams as an online learning platform during COVID-19 using system usability scale and technology acceptance model in India

“…Both in case of SUS and TAM neither the consumption platform nor the gender of the participants is found to have any significant effects (direct or interaction) on the perceived usability (scores obtained from SUS and modified TAM). Extant literatures suggest that the end-user experience depends to a great extent on the screen size of the devices used ( Maniar et al, 2007 , Pal and Vanijja, 2017 ). Similarly, the overall usability of the applications also increases with an increase in the screen real estate ( Robertson et al, 2005 ).…”

“…Since online learning primarily involves watching multimedia contents either during the live tutoring sessions, or when preloaded video contents are uploaded by the teachers to the learning platform, the type of device used for this purpose may affect the usability and consequently the student’s perception of the delivery platform. In fact, in the context of delivery of multimedia content there is enough evidence that the end user experience (often described in terms of the QoE – Quality of Experience) depends on the screen size ( Maniar et al, 2007 , Pal and Vanijja, 2017 ), and hence can vary between smartphones and laptops (or any computer in general). Moreover, now it has become a norm for the major application developers like Google, Microsoft or Apple to produce both mobile and web-versions of a particular application.…”

Right from the Start

“…When selecting options for the computer such as the size of the monitor and interface tools such as a mouse or a joystick, the teacher needs to consider the best tools for meeting the needs of preschoolers. Researchers agree that children learn significantly more when they can view video information on a large monitor (Maniar, Bennett, Hand, & Allan, 2008). A 21-to 26-inch monitor is useful for clearly displaying detailed information without distorting the images and is small enough to be portable within the classroom.…”
