Multiple pedagogical approaches, such as experimental experiences or computer-based activities, have been shown to increase student learning and engagement. We have developed a laboratory module that includes both a traditional "live" experimental component and a student-designed "virtual" computer simulation component. This…

In recent years, accreditation standards for international engineering education have led to a dramatic rise in the use of outcome-based education at universities. In this system, enticing new undergraduate students to science and engineering, although challenging, is the first important step toward building students' career competencies. An…

Carrying out classroom experiments that demonstrate Boyle's law and Gay-Lussac's law can be challenging. Even if we are able to conduct classroom experiments using pressure gauges and syringes, the results of these experiments do little to illuminate the kinetic theory of gases. However, molecular dynamics simulations that run on computers allow…

Learning quantum mechanics is challenging, even for upper-level undergraduate and graduate students. Research-validated interactive tutorials that build on students' prior knowledge can be useful tools to enhance student learning. We have been investigating student difficulties with quantum mechanics pertaining to the double-slit experiment in…

A chemistry laboratory experiment using everyday items and readily available chemicals is described to introduce advanced high school students and undergraduate college students to porous polymer membranes. In a three-step manufacturing process, a membrane is produced at room temperature. The filtration principle of the membrane is then…

Proteins are involved in nearly every biological process, which makes them of interest to a range of scientists. Previous work has shown that hand-held cameras can be used to determine the concentration of colored analytes in solution, and this paper extends the approach to reactions involving a color change in order to quantify protein…

All the cells of higher organisms have the same DNA but not the same proteins. Each type of specialised cell that forms a tissue has its own pattern of gene expression and, consequently, it contains a particular set of proteins that determine its function. Here, we describe a laboratory exercise addressed to undergraduate students that aims to…

The purpose of this laboratory experiment is to study fundamental concepts of kinetics and equilibria and the isotope effects associated with both of these concepts. The concepts of isotopes in introductory and general chemistry courses are typically used within the contexts of atomic weights and radioactivity. Kinetic and equilibrium isotope…

There is a growing interest in engaging students and the general public about the meaning and objectives of doing science. When it is possible students can learn by actively engaging in the practices of science, conducting investigations, sharing ideas with their peers, teachers and scientists, learning to work with measuring apparatuses, to…

A two-axis solar tracker and its interactive kiosk were designed by an interdisciplinary team of students and faculty. The objective was to develop a publicly accessible kiosk that would facilitate the study of energy usage and production on campus. Tracking is accomplished by an open-loop algorithm, microcontroller, and ham radio rotator. Solar…

Developing students' scientific literacy requires teachers to use a variety of pedagogical approaches including video as a form of instruction. In addition, using video is a way of engaging students in science ideas not otherwise accessible to them. This study investigated the merit of video clips representing scientific ideas in a secondary…

National Research Council polices (NRC, 2012a, 2012b) and the Every Student Succeeds Act (ESSA) of 2015 (Pub. L. No. 114-145) call for educators to have active roles in teaching to achieve new goals and purposes for education. A high priority is teaching content knowledge and information fluency skills that will result in deep learning, higher…

The objective of our program is to foster and facilitate authentic research experiences in middle and high school science courses. We do so by providing students with a complete experience in scientific experimentation and communication. The centerpiece is a set of experiment modules in which students investigate the effects of toxic chemicals on…

It was planned to introduce online pre-laboratory session activities to a first-year undergraduate physics laboratory course to encourage a minimum level of student preparation for experiments outside the laboratory environment. A group of 16 and 17 year old laboratory work-experience students were tasked to define and design a pre-laboratory…

Experimental investigations are an integral part of biology education because they demonstrate essential methods of obtaining knowledge in the natural sciences and generate high levels of learning activity. However, gender differences can arise during experimentation just as in other teaching situations. This article shows examples of social…
