A simple demonstration adaptable to classroom conditions is presented, which involves the preparation of raffle tickets using filter paper and the solution of selected fluorophores. With an appropriate dilution, the text written on the tickets is not visible to the naked eye; however, it becomes readable once put under a UV lamp. Besides being a…

Purpose: The paper identifies, outlines, and categorises establishment and operational factors that contribute to successful agricultural on-farm demonstration. Design/Methodology/approach: The paper is based on a literature review on demonstration activities and meta-analysis of 24 original case study reports from 12 European countries. Findings:…

Virtual laboratory is computer software that has the ability to perform mathematical modeling of computer equipment presented in the form of simulations. Virtual laboratory is not a substitute for real laboratory, but are used to complement and improve the weaknesses of real laboratory. This study aims to determine the effect of virtual laboratory…

Lesson planning is a challenge for teachers. However, the measurement and modelling of teachers' competence to plan lessons has received little attention. Especially, the question of which aspects are of central importance remains largely unresolved. The study aims to measure the challenge of structuring a lesson as an aspect of the…

The main objective of this intervention study was to investigate the effect of three teaching approaches, namely the traditional teaching method (TTM), a teacher-based demonstration experiment (TBDE) and a student hands-on experiment (SHE), on students' academic performance. A total number of 324 senior five students studying chemistry as one of…

The development of artificial intelligence competency on the flipped classroom with demonstration learning platform is the study that was conducted with the ideas to enhance the quality of Thai youths so that it would align with the instruction management in the age of artificial intelligence (AI), in which a number of AI applications have been…

Engineering educators naturally gravitate toward visual means for communicating concepts that would otherwise be extremely difficult to convey using words and numbers alone. With the emergence of three-dimensional (3D) printing as an accessible and cost-effective technology, it is now possible to develop customized models that enable students to…

Purpose: Poor uptake of agricultural innovations on weed management practices is a major factor responsible for low productivity. This paper examines how communication media can help improve farmers' adoption behaviour. Methodology: A sample of 725 Nigerian cassava farmers, exposed to agricultural innovation on weed management practices from…

Against the background of a data-driven education system that has detrimental effects on teachers' personal and professional lives, we report on an exploratory project in which seven primary teachers in England shared experiences of literacy teaching through generating 'small' data visualised on postcards. Thematic analysis of their data-sharing…

Hands-on experiments and teacher-based demonstrations are two standard teaching methods in secondary school when teaching chemistry in the laboratory. The available literature on these two teaching methods focuses on students' academic achievement. Most of this literature reports inconsistent results, and few studies examined teachers' and…

This paper builds on a previous study of the 'demonstration' as a signature pedagogy in design and technology (D&T). The demonstration is a fundamental pedagogical tool in practical subjects, for the development of learners' procedural knowledge, from observation and imitation to autonomy and adaption of a technique. As such, it tends to align…

In this article we describe a demonstration for most of the elements from the periodic table which together constitute the show "An Elemental Spectacle: A Guided Tour of the Darker Reaches of the Periodic Table."

In the main, convergent mixed-methods study on which this article reports, we explored Grade 12 accounting teachers' experiences of teaching in large classrooms in the Manzini region of Eswatini. As part of teachers' experiences, the methods that the teachers used to teach were also explored. Purposive sampling was used to select 25 accounting…

High-stakes assessments prominently influence what is done in secondary school science lessons ('washback' effects). It is therefore important that assessments of knowledge and understanding gained from practical work are constructed to reward and incentivise effective practices in practical work. To do that, they must differentiate between pupils…

This study aimed to examine the effect of three teaching approaches: The traditional teaching method, Teacher based demonstration experiment (TBDE), and the Student hands-on experiment (SHE), on students' conceptual understanding of solutions and titration. The data were collected using a chemistry achievement test (CAT) comprising of 30…
