There is a scarcity of studies that focus on how South African high school physical sciences teachers are grappling with chemical laboratory safety (CLS). This is despite the fact that the Curriculum and Assessment Policy Statements in the South African school system increased emphasis on laboratory activities in the physical sciences. Department…

Light emitting diodes have been used to determine Planck's constant in introductory physics laboratories. One common method relies on the energy of the light emitted by the LED and its relation to the energy gap in the solid of which the diode is composed. However, there could be a problem with the data that are collected for this experiment. For…

Acid--base chemistry is an important and challenging topic for virtually all chemistry students. Recent works have focused on conceptually linking molecular and symbolic representations to experimental evidence for many chemical concepts. In this work we describe a laboratory exercise designed to address students' conceptual challenges regarding…

This report presents a miniproject for teaching sustainability through the production of adsorbents from sewage sludge. The activity was tested during the Physical Chemistry II portion of an Agro-Industrial Engineering Course and lasted 4 weeks. The activities developed by the students included preparing the adsorbents ("in natura,"…

Resonant cavity perturbation as a means to measuring permittivity has been used since the early 1940s. It is attractive because it is non-contact, non-destructive and experimentally simple. Only recently, however, has the cost of a small analyser board become acceptably low that experiments can be carried out in schools and colleges. Using the TE…

Introductory physics laboratory experiments have typically been employed to reinforce classroom instruction instead of teaching students experimental design. Recent research has shown that lab experiments that focus on experimental practices are more effective at teaching students physics concepts. The experiment described in this paper has been…

Recognising effects of care departs from previous conceptions of care within science education as an idealised, ethical, and normative dimension of being, thinking and relating. In this article, we hesitate with care's moralistic qualities to render visible disruptive and complicit moments of care in complex ethical and political situated…

The most effective teaching and learning environments are those in which students are involved as active partners with faculty, and the greatest impact occurs when faculty go beyond asking students for feedback and instead involve them in design, production, and implementation. In this paper, we explore the process of student-faculty co-creation…

Informal academic conversations constitute a valuable addition to the repertoire of academic development initiatives. This article proposes that a Change Laboratory methodology may enhance the productivity of such conversations. Support for this proposal comes from a detailed analysis of participants' transformation of conversations on individual…

Forward genetics involves the identification of an unknown DNA sequence (genotype) associated with the expression of that sequence (phenotype). This is often done by generating variants (mutants) of that feature. One of the most practical methods is transposon mutagenesis, which facilitates the genotype-phenotype association through a sequence…

Anatomical dissection is known to serve as an integral tool in teaching gross anatomy, including postgraduate training. A variety of embalming techniques exist, resulting in different haptic and optical tissue properties. This study aimed to objectify learning outcomes and medical student perceptions related to the use of two widely used embalming…

Meaningful pedagogical reform requires good faculty training and support programs. Such support is particularly valuable when colleges and universities are trying to bring research and inquiry into the laboratory curricula under resource-limited conditions. In this situation, it may help to extend the scope of the faculty support program to…

Writing centers have long been a hallmark in supporting the development of student writers at North American academic institutions. Writing centers are often connected to a writing program or learning center open to all students for one-on-one tutorials regarding a writing project. Tutors function as coaches or collaborators, rather than as…

This IPA study examines how professional college writing tutors feel their role is understood and appreciated (or not). While writing tutoring is a hallmark service at many undergraduate institutions, there remains an incongruence between what tutors, professors, students, and administrators expect from the role. In order to bring more clarity to…

This paper addresses the challenge of integrating a dialog system with an ITS created for supporting procedural training in a 3D virtual environment. To this end, we first describe the desired features of the dialog to be provided to students in such system. Then, we explain some technical issues of our proposal such as the architecture; the…
