A physical model was used in a laboratory exercise to teach students about countercurrent exchange mechanisms. Countercurrent exchange is the transport of heat or chemicals between fluids moving in opposite directions separated by a permeable barrier (such as blood within adjacent blood vessels flowing in opposite directions). Greater exchange of…

Building on previous success with a digital pipet badge, an evidence-centered design approach was used to develop new digital badges for measuring the volume of liquids with a buret and making a solution in a volumetric flask. These badges were implemented and assessed in two general chemistry courses. To earn the badges, students created videos…

The hands-on laboratory experiments are frequently what spark students' interest in science. Students who are blind or have low vision (BLV) typically do not get the same experience while participating in hands-on activities due to accessibility. Over the course of approximately nine months, common chemistry laboratory experiments were adapted and…

Learning the meaningful use of the microscope is an essential requirement in school curricula. Modern science and medicine is hardly conceivable without the inclusion of microscopy. The number of didactic studies in this area, however, is negligible. Real microscopy is rarely used to gain knowledge in higher school years. Could the understanding…

The gap between graduate research and introductory undergraduate teaching laboratories is often wide, but the development of teaching activities rooted within the research environment offers an opportunity for undergraduate students to have first-hand experience with research currently being conducted and for graduate students to develop…

St. Olaf College recently added a Mathematical Biology concentration to its curriculum. The core course, Mathematics of Biology, was redesigned to include a wet laboratory. The lab classes required students to collect data and implement the essential modeling techniques of formulation, implementation, validation, and analysis. The four labs…

Many resources have been committed to research on science teaching pedagogies, resulting in a robust understanding of best instructional practices. Yet, exposure to excellent science instruction in elementary school is haphazard at best and often inequitable. Although the research community has attended to the role of teacher traits, such as…

Computer-based simulations can help students visualize chemical representations and understand chemistry concepts, but simulations at different levels of representation may vary in effectiveness on student learning. This study investigated the influence of computer activities that simulate chemical reactions at different levels of representation…

Anatomy has historically been a cornerstone in medical education regardless of specialty. It is essential for physicians to be able to perform a variety of tasks, including performing invasive procedures, examining radiological images, performing a physical examination of a patient, etc. Medical students have to be prepared for such tasks, and we…

Professionals require decision-making skills as well as technical knowledge. One might assume that their university education prepares them for this role yet, and least for future audit professionals, traditional text--and lecture--methods dominate teaching practice. This Participation Action Research study develops with auditing students a…

Democratic principles and human rights, the core values of the Council of Europe, informed the development of the "Common European Framework of Reference for Languages" (CEFR; Council of Europe 2001. "Common European framework of reference for languages: Learning, teaching, assessment." Cambridge: Cambridge University Press.…

This study aimed to explore lower secondary teachers' negotiation of the meaning of laboratory work in a professional development program. A total of 15 in-service teachers participated in the program. In the program, tensions between key ideas concerning traditional way of addressing laboratory work -- with emphasis on subject content and skills…

While much attention has been paid to the borders between those within and beyond the discipline of composition, the primary goal of this project is to examine the discourses which exist within composition and, subsequently, how these discourses might work to undermine pedagogy and scholarship. I take the position that even those working directly…

Research Findings: University-based child development laboratory programs have a long and rich history of supporting teaching, research, and outreach activities in the child development/early childhood education fields. Although these programs were originally developed in order to conduct research on children and families to inform policy and…

This paper presents a teaching experiment that explores the levitation of a disc of ferromagnetic material in the presence of the magnetic field produced by a single electromagnet. In comparison to the classical experiment of the levitation of a sphere, the main advantage of the proposed laboratory bench is that the uniform magnetic field…
