A research-based inorganic chemistry laboratory course is described. Using the defined protocol of a course-based undergraduate research experience (CURE), students undertake a self-designed research project to identify new catalysts for the dehydrogenation of ammonia borane. Students select ligands and metals, prepare and characterize catalysts…

A simple and inexpensive paper chromatography experiment that separates and identifies major organic acids in wine and fruit juices has been developed for introductory organic undergraduate students to teach the basics of chromatography. This experiment reinforces several concepts for students such as compound separation via extraction and…

Providing exposure to the process and methods of science is a fundamental goal of any general education college science course. This is largely because most students taking such courses are generally "not" science majors, so they are likely to take few, if any, other science courses. Meeting this goal can be a challenge in courses such…

It is hard to imagine learning science without doing laboratory or fieldwork. The research work in this paper assessed the state of physics laboratory teaching and learning resources in some selected universities in the South West geopolitical zone of Nigeria. The survey was carried out in five universities namely The University of Lagos,…

Physics inquiry can be interpreted as the construction of a cogent argument in which students apply inquiry knowledge and knowledge of physics to the systematic collection of relevant, valid, and reliable data, creating optimal scientific support for a conclusion that answers the research question. In learning how to devise, conduct and evaluate a…

Training in laboratory competency is an important part of biomedical student skill acquisition in preparation for both the workplace and accreditation. Virtual laboratory simulations are currently used in core modules at University of Westminster to prepare biomedical science students for laboratory sessions. These simulations are used for…

In 1827, Robert Brown noticed pollen suspended in water bouncing around erratically. It wasn't until 1905 that Albert Einstein provided an acceptable explanation of the phenomenon (Kac 1947): Brownian motion is the random movement of particles (e.g., pollen) in a fluid (liquid or gas) as a result of collisions with atoms and molecules. Movement of…

A low-cost turbidimeter, colorimeter, and nephelometer (TCN) multipurpose instrument applicable for undergraduate, graduate, and research laboratories is demonstrated within this work. The instrument relies on simple and robust electronics while using a PC sound card as an analog-to-digital converter. The performance of the instrument was…

Technology and Engineering (T&E) education has traditionally included safety as a core component of its curriculum and instruction. Recommendations for safety instruction can be found in manual arts and industrial arts documents (Christy, 1938). Safety was emphasized across all grade levels, including the elementary grades (Miller & Boyd,…

This study was carried out to determine teacher views on the use of technology to improve physics education in high schools. The sample of the study is 238 volunteer physics teachers. The study was carried out with the survey model and a five point Likert Scale was used in the study. The scale has a reliability coefficient of 0.92. Descriptive and…

The Maryland Action for Drug Discovery and Pharmaceutical Research (MADDPR) Program provides hands-on lab experience and mentoring to underserved minority high school students. With the inability to conduct an in-person STEM summer camp, the program transitioned to a virtual format in 2020. Thirty-three students and their PLTW teacher participated…

Due to the conditions imposed worldwide by the pandemic, students' access to school laboratories is limited, if not impossible. To provide students with raw experimental data to assess, analyse and reason out, we have filmed experiments that can be used in a flipped classroom. This paper presents an experiment which makes use of an array of six…

This three-paper dissertation addresses the experience and the implementation of evidence-based learning practices in science, technology, engineering, and mathematics (STEM)/biology education. Study 1 explored instructional strategies and student perceptions and preferences for various teaching practices in graduate and undergraduate classrooms…

Our goal was to understand how students' chemistry learning environments changed and how students responded to the wholesale transition to online learning. We deployed surveys to students enrolled in nine undergraduate chemistry courses at all levels. Survey 1 was deployed 2 weeks post-transition (N = 208); Survey 2, a week before semester's end…

In recent years, the applications of virtual reality (VR) in learning environments has received considerable attention. This attention occurs as a part of a wider trend seen since the early millennium. This trend is that of increasing attention being placed on modes of instruction that can supply greater realism and immersion in the science…
