Sahil Sood; Sean Fang; Alexander Chengyu Wang; Thomas Luong; Justin Keonhyoung Kim; Arkajyoti Sinha; John Jerome; Miriam H. Rafailovich – Journal of Chemical Education, 2023
Hands-on learning is a staple in high school science education, as it provides students with a fast-learning curve and a great degree of field competency. However, due to the safety risks associated with high school students in university chemistry laboratory settings, high school students rarely engage in authentic hands-on chemical learning. To…

Gudyanga, Remeredzayi – African Journal of Research in Mathematics, Science and Technology Education, 2020
There is a scarcity of studies that focus on how South African high school physical sciences teachers are grappling with chemical laboratory safety (CLS). This is despite the fact that the Curriculum and Assessment Policy Statements in the South African school system increased emphasis on laboratory activities in the physical sciences. Department…

Victoria Ly – ProQuest LLC, 2024
This dissertation explores the utilization of internet-connected devices to address the accessibility challenges associated with microscopy in the field of biology. Traditional microscopy devices are often costly, limiting their widespread adoption in laboratories. To overcome this barrier, we developed a cost-effective multi-well imaging device…

Albright, Haley; Stephenson, Corey R. J.; Schindler, Corinna S. – Journal of Chemical Education, 2021
A two-week summer camp was designed, implemented, and then updated for high school students focusing on organic chemistry, solar energy, and green chemistry principles. Students learn about laboratory safety, perform organic reactions, go on field trips, and take part in interactive lessons that focus on both fundamental chemistry topics as well…

Chemical safety, a practice of protecting humans and the environment in which they work and live from the deleterious effects of chemical substances, was investigated in this study in Nigerian secondary schools. Using a mixed-method survey, we investigated the awareness level and implementation of the best practices of chemical safety by 1246…

Pekdag, Bülent – Chemistry Education Research and Practice, 2020
This study explores the effect of video-based instruction on the safety rules in the chemistry laboratory on student achievement. The sample for the study comprised 61 ninth grade students enrolled in two different classes at a public high school. The students in the class designated as the experimental group (N = 32) were given video-based…

Obaya V., Adolfo E.; Osorio G., Carlos; Vargas, Yolanda Marina – Online Submission, 2020
Techniques are needed to train students in "writing to learn", whose main goal is to "learn to write". This work aims to exemplify how writing can be a teaching learning technique in an example in Chemistry to develop a correct understanding of the preparation of molar solutions in the laboratory. It is essential that this is…

Koulougliotis, Dionysios; Antonoglou, Lemonia; Salta, Katerina – International Journal of Science Education, 2021
This study aims at investigating students' awareness of green chemistry principles (GCPs) which are infused in two context-based projects that are related to socio-scientific issues, namely climate change and materials' recycling. At first, content analysis of the projects' activities showed the infusion of four GCPs. Subsequently, the students'…

Langley, G. Curtis; Tummons, John D.; Tracy Kitchel – Journal of Agricultural Education, 2018
Agricultural mechanics instruction includes a broad array of machinery, structures, and technical systems, as well as a diverse workforce. Virtually every aspect of agriculture has a mechanics component and a large portion of secondary agriscience curriculum is devoted specifically to teaching agricultural mechanics. Further, the agricultural…

Latourelle, Sandra M.; Elwess, Nancy L.; Ryan, Amy B. – Journal of Biological Education, 2020
Enzymatic activity is at the core of biological reactions. Understanding them and the chemical and environmental factors that affect reaction rates is critical for biology students. The laboratory experiment proposed here investigated these concepts, while requiring students to document, graph data, analyse results using statistics, and…

Reddy, Christopher – American Biology Teacher, 2014
Interactive television is a type of distance education that uses streaming audio and video technology for real-time student-teacher interaction. Here, I discuss the design and logistics for developing a high school laboratory-based science course taught to students at a distance using interactive technologies. The goal is to share a successful…

Zirkle, Chris – Tech Directions, 2013
Providing a safe classroom and laboratory environment should be the first priority of any career-technical and technology/engineering education instructor. Doing so not only increases the opportunity for student learning, but it also keeps instructors "out of hot water" with respect to legal issues of liability. In today's litigious…

Ribeiro, M. Gabriela T. C.; Machado, Adelio A. S. C. – Journal of Chemical Education, 2013
Two new semiquantitative green chemistry metrics, the green circle and the green matrix, have been developed for quick assessment of the greenness of a chemical reaction or process, even without performing the experiment from a protocol if enough detail is provided in it. The evaluation is based on the 12 principles of green chemistry. The…

Mattson, Bruce; Anderson, Michael P. – School Science Review, 2011
The development of syringes having free movement while remaining gas-tight enabled methods in chemistry to be changed. Successfully containing and measuring volumes of gas without the need to trap them using liquids made it possible to work with smaller quantities. The invention of the LuerLok syringe cap also allowed the gas to be stored for a…
