This paper describes a first-year undergraduate exercise involving the synthesis of an "unknown" polyiodide salt, (NMe[subscript 4])[I[subscript 5]], and the determination of its formula using the classic iodine-thiosulfate (iodometric) titration. The exercise introduces students to simple synthetic and titrimetric techniques, assists…

Due to a growing awareness of environmental issues, green chemistry concepts are increasingly being incorporated into the undergraduate organic chemistry lecture and laboratory component. This minireview summarizes environmentally friendly organic chemistry experiments suitable for undergraduate laboratories. Whenever feasible, LD[subscript 50]…

The acoustic resonance in four glass Helmholtz resonators with diameters of 70, 52, 40, and 32 mm was detected in the frequency range of 360 to 1700 Hz using the simple experimental setup presented in this paper. The measured amplitudes of acoustic pressure required correction since the sound pressure amplitude of the loudspeaker used was not…

Capstone teaching laboratory activities can serve as a crucial part of the undergraduate learning experience. With this in mind, a laboratory activity that combines synthesis and multiple characterization techniques has been developed for an upper-division, laboratory-based inorganic course. Complexes of Cu(II) and Ni(II) of the amino acid glycine…

This paper describes a laboratory experiment that was designed to improve engineering education in fluids and hydrology courses. The laboratory module is part of a broader effort to enhance the undergraduate engineering laboratory curriculum to incorporate modern pedagogical methods and to improve a defined set of student outcomes. The…

Researchers of graduate student success have recently begun engaging in studies aimed at establishing a better understanding of what practices best assist in graduate student retention and degree completion. Simultaneously, Writing Center scholars have been making a concerted effort to undertake empirical research focused on the everyday work of…

The Next-Lab project provides free web-based resources supporting teachers in enhancing students' learning experiences. By including online laboratories, experiments otherwise difficult or impossible to perform are facilitated (e.g. crashing meteoroids into Earth). This article briefly presents the project and opportunities offered to teachers and…

In this paper we discuss the role of transduction in the teaching and learning of science. We video-filmed pairs of upper-secondary physics students working with a laboratory task designed to encourage transduction (Bezemer & Kress, 2008). The students were simply instructed to use a hand-held electronic measurement device (IOLab) to find the…

To date, few general chemistry laboratory studies have included affective measures despite calls for more research on aspects of this domain. This shortage of studies may be partially due to the scarcity of affective measures that have been designed for, or tested in, the college laboratory setting. To provide measures for use in this environment,…

Systems thinking is highly desirable for re-imagining chemistry education, which will help in the development of an integrated and sustainable approach that takes into account the interdependence of a system under study with other components of the ecosystem rather than practicing a fragmented approach. Thus, to develop a systems' perspective into…

The goals of this advanced physics laboratory course emphasized not only to improve students' physics knowledge but also spectrum scientific abilities in particular for preparing their future-ready competencies. One of those scientific abilities was initiated to study that was "the ability to design experiment". It was the fundamental…

We discuss the use of a simple piece of equipment made of a 50 mL syringe attached to a 2 mL graduated pipet to demonstrate Boyle's law and Charles's law. A plot of the hydrostatic pressure against the reciprocal of the volume of the gas read from the equipment is linear as discussed in the paper and gives the atmospheric pressure at the…

Success in undergraduate chemical experiments requires students to develop knowledge and skills of instrumentation, equipment, and chemical techniques. In this technology report, we propose an adaptable and user-focused strategy to improve students' foundational skill and proficiency with chemical laboratory techniques and instrumentation. The…

Next-generation sequencing (NGS)-based methods are revolutionizing biology. Their prevalence requires biologists to be increasingly knowledgeable about computational methods to manage the enormous scale of data. As such, early introduction to NGS analysis and conceptual connection to wet-lab experiments is crucial for training young scientists.…

The use of virtual labs in higher education is gaining growing interest, with different debates in the literature about their role in addressing learning outcomes and balancing hands-on activities. This study seeks to understand how labs can be virtualised and thus structured to contribute to engineering education, by adopting an innovative…
