During the fall of 1947, the first building for the Naval Arctic Research Laboratory (NARL) was constructed, which consisted of a quonset hut retrofitted as a laboratory. Scientists arrived in Barrow (Utqiagvik), Alaska, the northernmost village in the United States, not long after. The remainder of NARL was built two miles outside the village…

The present paper reports upon the design and implementation of a novel practical work pedagogy that is shown to increase students' retention of practical procedures. The chemistry exams, for 15 to 16-year olds in England, will be assessed entirely through terminal examination questions from 2018. Longer term retention of learning is critical if…

This study uses graphs of conductivity measured by a microcomputer-based laboratory (MBL) to promote students' macro, micro, and symbolic representations when learning about net ionic reactions (NIR). A total of 54 students, aged 14-15 years old participated in this research, and were randomly divided into an experimental group (N = 27) and a…

This article presents the structure of the organic chemistry laboratory Course "Synthesis and Extraction of Drugs" that is included in Modena University (Italy) in the third year of the five-year "Chemistry and Pharmaceutical Technologies" degree program. This course is unique in its kind, and it aims to provide students with…

In this article, a low-cost, simple, and rapid fabrication of paper-based analytical devices (PADs) using a wax screen-printing method is reported here. The acid-base reaction is implemented in the simple PADs to demonstrate to students the chemistry concept of a limiting reagent. When a fixed concentration of base reacts with a gradually…

This paper presents a set of laboratory classes to be taught as a part of a 1 year calculus-based physics class. It is composed of 7 modules designed to bring together experiments and computer simulations. Each module uses both simulations and experiments to address a phenomenon under study, and lasts for 3 weeks (21 weeks total for the whole…

This study aims to determine the influence of learning models and numerical ability of students' chemistry learning outcomes on Thermochemical materials, as well as the interaction between learning models through the use of laboratory and numerical ability. The study was conducted on the students of grade XI IPA SMA N 1 Stabat consisting of 9…

3D printing technology has an enormous potential to apply to chemical engineering education. In this paper, we describe several designs of 3D printed mesoreactors (Y-shape, T-shape, and Long channel shape) using the following steps: reactor sketching, CAD modeling, and reactor printing. With a focus on continuous plug flow mesoreactors (PFRs, i.d.…

Electronic laboratory notebooks are gaining in popularity in industry and academia. Various types of electronic laboratory notebooks exist, and a variety of tools can be used for these forms of notebooks. Some tools are commercial products dedicated to being electronic notebooks, while individual organizations can develop ones for their own needs…

Experimental work in the research of astronomical phenomena is often difficult or even impossible because of long-lasting processes or too distant objects and correspondingly too expensive equipment. In this paper, we present an example of observation of the Moon, which is our nearest astronomic object and therefore does not require professional…

This study is an attempt to identify the level of awareness of safety measures practiced in school laboratories among pre-service Science teachers at Najran University. It also aims to identify the sources of safety measures awareness and the statistically significant differences among the sample responses due to specialization and grade…

The current study presents an evaluation of the laboratory instructional tasks prepared based on innovative teaching approaches (research-inquiry, problem solving, project, argumentation and web-based interdisciplinary learning approaches) designed to enhance science teachers' biotechnology knowledge, awareness and laboratory experiences. The…

In classroom science laboratories, unlike a real science laboratory, the teacher can guide students away from potential dead ends and toward data that are most likely to result in accurate conclusions. Sometimes, though, allowing students to pursue dead ends and to collect "bad" data can provide especially rich learning opportunities.…

Testing water samples for arsenic contamination has become an important water quality issue worldwide. Arsenic usually occurs in very small concentrations, and a sensitive analytical method is needed. We present here a 1-day laboratory module developed to introduce Earth Sciences and/or Chemistry student undergraduates to key aspects of this…

Some misconceptions about physics are hard to change. For example, students continue to believe that heavier objects fall faster than light ones, even after a year of physics instruction. Physics misconceptions are persistent. Light objects do fall more slowly if their size-to-weight ratio is sufficient for drag to be appreciable. Motion through a…
