At-home chemistry experiments are increasingly important to enable high-quality online and hybrid instruction. These class modalities provide significant challenges and also dramatically expand the accessibility of education to those who work or care for family during traditional school hours or have significant commutes to campus. This work…

The switch to online learning required a creative solution to allow for the experiential learning outcomes of the program to be satisfied when access to physical spaces and equipment was restricted. This paper describes a collaborative process between technical and support staff as well as research and teaching faculty that led to the creation of…

Assistive technologies remain important in supporting student learning in both in-person laboratories and the online laboratory environment. In this article, we describe an adaptation of a smartphone technology called the Color Blind Pal app to aid students in complementing online laboratory assignments in a general chemistry course. The app was…

Due to the COVID-19 pandemic, mandatory changes were required in the field of education, as in many other fields. One of these fields is a teacher training programme, which includes teaching practice. It has become of great importance that pre-service science teachers, who frequently include experiments in their teaching practices in face-to-face…

The target of this study is to determine the minimum angle of deviation of a prism which is one of the optical experiments. Thus, the aim is to state the refractive index of a prism. In this context, the Tracker program, which might also be utilized in terms of distance education purposes, was preferred. The videos of the experiments were recorded…

Due to the conditions imposed worldwide by the pandemic, students' access to school laboratories is limited, if not impossible. To provide students with raw experimental data to assess, analyse and reason out, we have filmed experiments that can be used in a flipped classroom. This paper presents an experiment which makes use of an array of six…

In the Spring 2021 Organic Chemistry Lab class at Penn State Schuylkill, COVID-19 restrictions and uncertainty required a flexible plan. The first 4 weeks of 15 were fully remote, and videos of standard organic techniques were used, followed by an exam. In the next 5 weeks, some students were in the lab and some were remote. A document camera was…

In times of the explosion of distance learning, because of emergency due to the pandemic, smartphone sensors and cameras are extremely valuable for teachers as they allow students to perform significant experimental activities in their own homes. The open-source software Tracker can be used in combination with the smartphone camera to perform…

A wood cantilever of length ~2.5 m is driven into resonance using the hand as a simple driver. Video recordings of these oscillations are analyzed to determine experimental second harmonic (n = 2) damped resonance frequencies. These frequencies are compared to theoretical ones, obtained from measurements of elastic moduli, damping properties, and…

A straightforward experimental set-up, requiring a two-liter bottle, a ruler and a stopwatch, is used to provide data appropriate for modelling with Torricelli's Law in the simplest case, and a more sophisticated differential equation when losses are taken into account and a pipe extension is considered. With only an exit hole included in the…

Remote access technology in STEM education fills dual roles as an educational tool to deliver science education (Educational Technology) and as a means to teach about technology itself (Technology Education). A five-lesson sequence was introduced to 11 and 12-year-old students at an urban school. The lesson sequences were inquiry-based, hands-on,…

Abrupt disruptions to academia, due to the COVID-19 pandemic in Spring 2020, have brought unprecedented challenges in teaching, yet it has brought many lessons, driving the development of strategies in response to the crisis. The general chemistry laboratory course is often considered difficult to teach, due to students' heterogeneous chemistry…

A remote experiment was developed and carried out to create a phenol/water phase diagram using a low-cost automated data collection system and an online video broadcast. Both the data and video from the experiment were transmitted in real-time. The remote lab experiment was evaluated using qualitative and quantitative questionnaires filled out by…

A novel technology that employs computer vision (CV) to carry out an automatic titration experiment is presented. The experiment is designed to facilitate understanding of the basics of the CV technology and its application in chemistry among undergraduate students. The standard chemical procedure of titration has been chosen, since it is…

When the COVID-19 pandemic forced school closures, science, technology, engineering, and mathematics (STEM) teachers were left with the challenging task of devising ways for students to conduct experiments at home. This was necessary because experiments and other hands-on activities are integral to STEM education and are linked to the development…
