Practical solid state diodes and transistors have made glass valve technology nearly obsolete. Nevertheless, valves survive largely because electric guitar players much prefer the sound of valve amplifiers to the sound of transistor amplifiers. This paper discusses the introductory-level physics behind that preference. Overdriving an amplifier…

This study aims to examine the opinions of foreign language instructors who teach at preparatory classes through distance education during the pandemic. Based on this objective, five instructors working at a School of Foreign Languages at a state university in Turkey were interviewed and their opinions regarding the positive and negative aspects…

Dynamic visual tools such as MATLAB have inbuilt features which are believed to be able to empower students to learn through the visualisation of three-dimensional objects. While student learning through MATLAB has been investigated regarding students in urban settings, only a handful of studies have investigated how MATLAB can assist students in…

Sri Lanka's education system was suddenly shifted from classroom-based free education to online-based distance learning as an emergency teaching and learning method (ETLM) in response to the COVID-19 pandemic lockdown. This study examines how various stakeholders used online-based distant learning as an ETLM, and highlights the lessons learned…

With the technological improvements of innovative portable recording gadgets, augmented researchers' interest in exploring students' visual attention in their natural and normal occurring classrooms. The purpose of this study was to gauge students' visual attention in their Mathematics and English classrooms. This article reports on a study…

Following the closure of educational institutions, after the outbreak of COVID-19 in December 2019, even though grossly unprepared, universities sent their students home and adopted the online teaching approach to continue with the education of their students. However, little was done to assist most African students who were living in the rural…

When it comes to paying attention to the suprasegmental features of their speech, most learners of English seem to be unaware that such phenomena as stress, pitch, duration, and pausing can be of great importance regarding mutual intelligibility. Since they carry a considerable weight of establishing an intelligible conversation, it is argued that…

Molecular processes are highly complex, and are frequently difficult for high school and college students to comprehend. Because of the importance of visualization in learning, along with formative assessment of student understanding, utilization of 3D modeling software aids both educators and students alike. The activity described below required…

Aim: Tablet technology can play a valuable role in supporting learning for primary school children, but its implementation for children in the early years or for with those with learning delays has received limited focus. The aim of this study was to enhance understanding of the interaction between child, technology, and conditions for…

This article reports the design of a course blended through a small private online course in a Chinese university EFL context, with an emphasis on the blended learning environment created thereby and on learners' perceptions of their blended learning. In a survey-based approach, 1603 students' experiences of blended EFL learning in two consecutive…

The purpose of this paper was to demonstrate University and High School collaboration through a Service Learning exercise. Pedagogical collaboration between the local Prescott High School and senior level mechanical engineering students from Embry Riddle Aeronautical University (ERAU) in Arizona had great benefits to both schools and the students.…

This research study was conducted to identify core practices of enacting effective mathematics pedagogy with GeoGebra, a software application for teaching and learning mathematics. Eleven Ghanaian in-service mathematics teachers were engaged in a twelve-month professional development programme where they developed GeoGebra-based mathematics…

In psychology departments in South Africa, the Statistical Package for the Social Sciences (SPSS) is routinely used for quantitative analysis. While SPSS has a user-friendly interface, it does not permit application of some of the more sophisticated analytic approaches and therefore has limited functionality. The programming language R can perform…

Since 2016, the Advanced Distributed Learning (ADL) Initiative has been developing the Total Learning Architecture (TLA), a 4-pillar data strategy for managing lifelong learning. Each pillar describes a type of learning-related data that needs to be captured, managed, and shared across an organization. Each data pillar is built on a set of…

This article describes the redesign of a project-based course on soft and biological materials to include computational modeling. Including the construction of computational models in the course is described as a shift from constructivism--a theory that characterizes the development of formal reasoning, to constructionism--a theory that focuses on…
