Students use causal reasoning in their everyday lives to generate hypotheses as to why an event occurred, or to create predictions about future events. Also, causal reasoning skills are critical in the laboratory setting and are needed to (1) look for patterns in collected data, (2) determine if relationships exist between variables, and (3)…

Enhancing student employability is a key aspect of any chemistry-based degree; however, embedding such activities in the curriculum is often challenging. Placements (internships in the USA) or experiential visits are the most widely used approach, but these are not always inclusive. Work-integrated learning (WIL), the practice of combining…

Our main goal was to investigate if and how using multiple immersive virtual reality (iVR) simulations and their video playback, in a science course, affects student learning over time. We conducted a longitudinal study, in ecological settings, at an undergraduate field-course on three topics in environmental biology. Twenty-eight undergraduates…

In the midst of a global pandemic in spring 2020, physical chemistry faculty gathered to share strategies and resources for teaching remotely. During this conversation, instructors created a shared document compiling the challenges they faced in spring 2020 and ways to improve teaching and learning in the physical chemistry classroom and…

Introductory physics for life sciences (IPLS) courses have emerged as a type of physics course within the introductory courses sequence. The interdisciplinary aspects of these courses as well as the diverse student populations that they serve create significant challenges for instructors who choose to design and deliver them. The Living Physics…

Building on literature addressing doctoral student socialization and scientific research groups, we qualitatively explore the gendered nature of laboratory rotations for 54 women pursuing STEM doctorates. Using in-depth interviews and a feminist phenomenological approach, findings highlight how women (re)constructed strategies to select lab…

This dissertation examines, in three studies, undergraduate student experiences in social aspects of online learning when conducting remote physics laboratories. The first quantitative, observational study examined introductory students' epistemological, socialization, and help seeking views (N=998). Parametric and nonparametric tests indicated no…

A laboratory experiment often performed in an introductory electricity and magnetism course involves the mapping of equipotential lines on a conductive sheet between two objects at different potentials. In this article, we describe how we have expanded this experiment so that it can be used to illustrate the electrostatic properties of conductors.…

We have designed a 4 h physical chemistry laboratory to introduce upper division students to electrochemistry concepts, including mixed valency and electron transfer (ET), using cyclic and differential pulse voltammetries. In this laboratory practice, students use a ferrocene dimer consisting of two ferrocene centers covalently bonded through a…

Examination of photographic processes from the 19th century to the present digital age is an effective means to intellectually engage nonscience majors with science. A laboratory course for nonscience majors exploring these processes is described in this article. Ionic and covalent compounds, oxidation-reduction reactions, precipitation reactions,…

Chromatin immunoprecipitation followed by qPCR analysis (ChIP-qPCR) is a widely used technique to study gene expression. A large number of students in molecular biology and more generally in life sciences will be confronted with the use of this technique, which is quite difficult to set up and can lead to misinterpretation if not carefully…

The clinical laboratory science field requires an abundance of technical knowledge; however, the importance of implicit or tacit knowledge gained through observation and practice is often discounted in this field, even though it is a critical part of reflective thinking, critical thinking, and reflective practice. The "de-skilling" of…

Nanostructures of organosilanes, thin metal films, and protein nanopatterns were prepared and analyzed with atomic force microscopy (AFM). Organosilanes with designed functional groups were used to selectively pattern green fluorescent protein at the nanoscale using protocols developed with particle lithography. Mesospheres are deposited onto a…

The Curriculum and Assessment Policy Statement (CAPS) reforms in the South African school system came with an increased emphasis on laboratory practicals for the physical sciences. While reform implementation is known to be fraught with a myriad of challenges, for science teachers such significant changes in the practical components magnified the…

In this research, the laboratory perceptions of pre-service science teachers with different goal orientations in analytical chemistry courses in which an inquiry-based laboratory approach had been adopted were examined in a case study. From the pre-interviews conducted with 37 pre-service science teachers, 3 preservice science teachers with…
