Williams; Zachary Conley; Hinton Antentor Jr. – Advances in Physiology Education, 2024
Physiology is an important field for students to gain a better understanding of biological mechanisms. Yet, many students often find it difficult to learn from lectures, resulting in poor retention. Here, we utilize a learning workshop model to teach students at different levels ranging from middle school to undergraduate. We specifically designed…

Triboluminescence is a fascinating phenomenon that can engage students' interest in chemistry. However, safe, cost-effective, and accessible laboratory experiments featuring highly triboluminescent substances are limited. To bridge this gap, we present a simple, rapid, semimicro test tube preparation of the visually engaging manganese complex…

Beshir A. Hussein; Getabalew Shifera – Journal of Chemical Education, 2022
Accidents occur in laboratories due to a lack of proper knowledge regarding laboratory safety measures, perilous attitudes, and unacceptable laboratory practices. This study assessed the chemistry laboratory safety knowledge, attitude, and practice (KAP) of teachers and laboratory technicians in secondary schools of South Wollo, Ethiopia. The…

Kvittingen, Lise; Sjursnes, Birte Johanne – Journal of Chemical Education, 2020
An easily constructed and inexpensive polarimeter with an optical rotation angle resolution of about 0.5° is presented. It is made from small pieces of polarizing film, 2 LEDs, a protractor, and a few wires, all held in place with plastic interlocking toy bricks, such as Lego bricks. The instrument was used to demonstrate the optical rotation of…

Suartini, Tuti – SAGE Open, 2019
The development of vocational high school teaching and learning in Indonesia becomes very important when the country is faced with the demands for quality workers that will be necessary to face the free trade era of the 2015 ASEAN Economic Community (AEC). To anticipate this, solutions in terms of instructional strategies should be prepared,…

Noei, Nima; Imani, Iman Mohammadi; Wilson, Lee D.; Azizian, Saeid – Journal of Chemical Education, 2019
A low-cost and simple setup to measure the densities of liquids is introduced herein. The results and reliability of this setup were evaluated for pure liquids, water-ethanol binary mixtures, and aqueous NaCl solutions. The constructed densitometer provided density values with acceptable relative errors (less than ±3.0%), which were compared to…

Simpson, Tyler; Chiu, Yu-Chun; Richards-Babb, Michelle; Blythe, Jessica M.; Ku, Kang-Mo – Biochemistry and Molecular Biology Education, 2019
Allelopathy plays crucial roles in invasive plant viability and agricultural production systems. However, there is no well-established hands-on learning activity to teach the concept of allelopathy. Nor is there an activity which allows students to gain knowledge about glucosinolates and their corresponding enzyme, myrosinase, which are present in…

Coclasure, Blake C.; Thoron, Andrew C. – Journal of Agricultural Education, 2018
The purpose of this synthesis of literature was to identify and analyze existing research that used experimental or quasi-experimental design in school-based agricultural education. This study utilized published articles in the "Journal of Agricultural Education" from the years 2006 through 2016. The study identified 35 articles that met…

Tran, Trinh-Ba; van den Berg, Ed; Ellermeijer, Ton; Beishuizen, Jos – Physics Education, 2018
Research has shown that the objectives for laboratory teaching--just as with other teaching methods--are often not achieved and that many laboratory sessions are ineffective and yet expensive in terms of pupil and teacher time, and facilities. There are several reasons for this, but one reason is that instructions for many lab activities are too…
