Observational learning enables us to make decisions by watching others' behaviors. The quality of such learning depends on the abilities of those we observe, but also on our beliefs about those abilities. We have previously demonstrated that observers learned better from demonstrators described as high vs. low in ability, regardless of their…

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…

The simple demonstration presented, herein, involves the combustion of acetylene liberated from the rapid hydrolysis of 0.50 g of calcium carbide. The unsaturated hydrocarbon formed burns with a yellow sooty flame in air. This acetylene-air flame being visually attractive is often misused by those attempting to showcase their illusory magical…

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:…

Purpose: 360° immersive videos may be useful in procedure-based healthcare settings. We hypothesized that extended reality (XR) neonatal intubation education is a feasible alternative to live demonstration in skill and knowledge transfer. Methods: This was a prospective single center evaluation of an educational XR intubation video using Premature…

Instructional methods are the cornerstone of all teaching and learning strategies. This study explored instructional method use by early, middle, and later career agricultural education teachers. One-hundred nine teachers responded to an online questionnaire and were evenly split in terms of gender. Cooperative learning, demonstration, and lecture…

For decades, chemical modeling sets have allowed the user to manipulate atoms and bonds using plastic/wooden ball and stick materials. Here is a design for an interlocking toy brick modeling set in which the undergraduate nursing student can manipulate electrons during the simulated chemical bonding exercise. The author presents a teaching and…

A 2.7 m long stringless pendulum was set up to measure the coefficient of rolling friction of various balls, at higher rolling speeds than usually observed with a short stringless pendulum. The arrangement is easy to set up and makes an impressive classroom demonstration as well as an interesting laboratory experiment.

Blue (B), yellow (Y), red (R), and green (G) color-changing dye was used in a general chemistry course for first-year undergraduate students with nonscience majors to highlight the redox reactions written as the gain and loss of hydrogen. The first experiment is a vibrant color variation using a synthetic dye of indigo carmine. The second…

For the present lab demonstration, we have developed fluorescent indicators to detect the end point in microscale redox titration of ferrous ions in permanganometry, cerimetry, and dichrometry. Microscale redox titrations were carried out effectively in micromolar(µM) concentrations and semi-microvolumes of the analytes. At the end point,…

The prevalence of online instruction highlights the importance of videos in education. Pedagogies that include elements that actively engage students are accepted as an improvement over more passive modes of instruction. How can we transfer the advantages of active engagement to instruction via video? Previous research on instructional videos has…

Advanced postgraduate medical education for health-care professionals is constantly evolving. Understanding facial anatomy and especially its vascular system is crucial when performing soft tissue filler injections to avoid adverse events including tissue loss or irreversible blindness. Standard anatomical resources often fall short of elucidating…

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…

This study explored the impact of interactive e-books on the viewing behaviors of children in science demonstrations at museums. To conduct this study, an interactive e-book on a pendulum experiment was developed and integrated into a physical science demonstration at a museum. Two scientific demonstrations were conducted in this study. The first…

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…
