An NMR tube cleaner that is quickly and easily constructed from everyday laboratory equipment is described. This cost-effective option removes the need to purchase a fragile, more expensive model. The small footprint of the device lends itself to being given a permanent place in the laboratory, but it is also simple enough to disassemble and…

The variation of the period of oscillation of a pendulum with the amplitude is known as "circular error" to clockmakers, and can easily be observed even without modern laboratory instruments. There have therefore been many approximate formulae for the pendulum period as a function of the amplitude, but the simple equation due to Denman,…

Laboratory experimentation providing students with hands-on experiences can greatly enhance the teaching and learning of physics. However, traditional hands-on laboratories are very expensive, limiting the possibilities for practical activities. In addition, limited time for laboratory practices prevents teachers and students from conducting…

Laboratory courses can help students learn in a meaningful way. In the past, students encountered difficulties in chemistry laboratory courses due to limited access to equipment and space for practicing experimental operations. In recent years, virtual laboratories have allowed students to repeatedly practice in order to achieve their experimental…

We redesigned our undergraduate laboratories to create a structured sequence that continuously improves the learning experience of students. We utilized a PBL and PjBL approach in which students are progressively introduced to ill-structured open-ended problems, the development of projects, and the creation of research products. We dynamically…

Ametal leaf electroscope has often been used for teaching electrostatics. For example, Fig. 1 is a very early one demonstrating electrostatic induction with a gold leaf electroscope. Alternatively we can charge the electroscope by touching a charged object to it. In both cases, induction or charging, the metal leaves push away from each other for…

Laboratory experiments provide students a tangible means of understanding dry, abstract concepts. A simple and engaging introductory wet chemistry laboratory has been developed relating quantum mechanics to color, which has been implemented for a class of about 600 students per academic year for over three years at Brown University. Color is an…

The topic of electric and magnetic fields is fundamental to the physics curriculum in both high school and college. The applied aspect of this topic has triggered the rapid development of modern technology in this era. This paper reported a remote data acquisition system developed for experiments with magnetic fields by coils to support…

The Pernkopf atlas is a well-known case study of anatomists' ethical transgressions in using bodies of Nazi victims for professional purposes and the relevance of this history for today. This study examines the likely sources from which Pernkopf developed his own anatomical gaze and pedagogical approach to depicting the human body. It also…

Teaching in rural schools is frequently marked by challenges ranging from restricted technological infrastructure and geographical remoteness to sparse professional development. Guided by the Unified Theory of Acceptance and Use of Technology (UTAUT), this paper reports findings from a sequential explanatory mixed-methods study that investigated…

Course-based undergraduate research experiences (CUREs) have grown in popularity, particularly within introductory biology courses, to provide more students with authentic research experiences. CUREs have been shown to have many of the same positive effects as conventional research experiences; however, most assessments of CUREs lack an…

During the years 2020-2022, COVID-19-related restrictions led to fewer in-person lab offerings in Neuroscience and Biology courses, resulting in negative impacts on students' skills and confidence. In this study, we investigate the impact of a co-curricular undergraduate lab skills program, the Practical Skills Passport (PSP), on student lab…

Cultural-Historical Activity Theory has contributed significantly to studying and promoting educational change. Its distinctive concepts inform an approach to interventionist research called the Change Laboratory This paper reports on a Change Lab in an Australian secondary school resulting in major changes for students studying for the Higher…

Electrochemical characterization techniques are essential for studying and developing advanced materials across various fields, from corrosion science to energy storage, photovoltaics, and bioelectrochemistry. However, these techniques are often under-represented in educational curricula. This practical guide with a hands-on laboratory experiment…

Undergraduate students in science classes are more engaged and demonstrate increased performance when instructional methods include authentic science practices and active learning strategies. Non-majors students (i.e., those enrolled in science classes to fulfill a degree requirement) typically receive instruction that is more lecture-based and…
