With the increase in life expectancy and the rapid advancement of digital technology, older adults often face challenges where formal learning opportunities are scarce. Consequently, they are compelled to rely on instructional videos for continuous learning. However, many older adults struggle with low self-efficacy and motivation. Although…

Background: Video lectures which include the instructor's presence are becoming increasingly popular. Presenting a real human does, however, entail higher financial and time costs in making videos, and one innovative approach to reduce costs has been to generate a virtual speaking instructor. Objectives: The current study examined whether the use…

This research studied the impact of language barriers and cultural experiences on students' perceptions at the University of North Texas. The population of this study were students who had taken a class with a non-native speaking instructor and those who hadn't. Following a mixed-method research approach, online surveys were distributed to the…

Background: Active learning used in science, technology, engineering, and mathematics (STEM) courses has been shown to improve student outcomes. Nevertheless, traditional lecture-orientated approaches endure in these courses. The implementation of teaching practices is a result of many interrelated factors including disciplinary norms, classroom…

Via AI video generators, it is possible to create educational videos with humanistic instructors by simply providing a script. The characteristics of video types and features of instructors in videos impact video engagement and, consequently, performance. This study aimed to compare the impact of human instructors and AI-generated instructors in…

Introductory physics for life sciences (IPLS) courses have emerged as a type of physics course within the introductory courses sequence. The interdisciplinary aspects of these courses as well as the diverse student populations that they serve create significant challenges for instructors who choose to design and deliver them. The Living Physics…

The impacts of COVID-19 have been widespread, and the education sector has not been immune to its effects. In March 2020 Australian universities were forced into a shutdown, which prompted an unanticipated, sudden shift in education, from on-campus and face-to-face to an off-campus and online mode of teaching and learning. This paper describes the…

Lectures prevail as a ubiquitous teaching and learning method across universities worldwide. Whereas lectures have been conceptualized from language-centred perspectives, lectures' materiality as linked to their socio-cultural and historical meanings have been scarcely explored. To address this gap, we tackle the materiality of communication in…

Purpose: Research on EMI (English-Medium Instruction) has addressed the extent to which content lecturers speaking in their L1 perform as well as when they lecture in English. In this study a lecturer who gave the same lecture in his L1 (Catalan) and English was observed to examine if and how transitioning from one language to another impacts his…

This paper reports on the process of understanding myself and my pre-service teacher education students better through my lecture reflections and deliberations with critical friends as I taught a South African film entitled Tsotsi. Conversations with colleagues deepened my analysis as I was challenged to revisit my musings on lecture reflections,…

Background: Faculty might disclose personal information in order to illustrate a concept related to course material. However, the impact of self-disclosing potentially personal information (e.g., medical or mental health) is unclear. Objective: The purpose of this study was to determine how students perceive professors who self-disclose personal…
