Virtual reality (VR) provides significant opportunities for students to experience immersive education. In VR, students can travel to the international space station, or go through a science experiment at home. However, the current tactile feedback provided by these systems do not feel real. Controllers do not provide the same tactile feedback…

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…

Analogies are useful tools instructors can use to help make challenging concepts less abstract by drawing connections to familiar contexts. In this paper we provide an overview of the various analogies published in the education literature that are situated in the context of enzyme kinetics, including narrative-based analogies (analogies intended…

At first glance, scientific laboratory experiences might appear to be challenging to move to the cloud. Skeptics may point to sensory feedback limitations and inequivalence of student outcomes. However, emerging data increasingly provide evidence that scientific laboratory courses are not only amenable to online learning, but also can deliver…

A low-cost and easy-to-use water recirculation system for a condenser apparatus was designed and installed in an organic chemistry teaching laboratory. Relying on gravity and a small pump for water circulation, it supplies four stations simultaneously. The water recirculation system works very well with condensers used for distillation and reflux…

An undergraduate organic chemistry laboratory experiment involving the breakage of amide C-N bonds is reported. Whereas amides are typically considered stable species due to well-established resonance effects, this experiment allows students to cleave the amide C-N bond in a nickel-catalyzed esterification process. Moreover, students perform the…

The bioinspired polymer polydopamine is synthesized and deposited on semiconductive glass substrates under different synthesis conditions (pH and oxidant type). Electrochemical methods are used to verify polymer deposition on the substrate and to examine the charge transfer properties of the obtained coatings. The presence of aromatic rings from…

We have designed an Arduino-based experiment to check the linear relationship between charge and voltage drop in a capacitor. The electric charge stored in a capacitor is determined by the numerical integration over time of the electric current during the charging or discharging processes through a resistor. Instead of using scientific software to…

Beginning abruptly in the second half of the Spring 2020 semester at Purdue University, we modified our teaching approach in Introductory Soil Science and Forest Soils courses (AGRY 255/270) with a combined annual enrollment of [approximately]370 students to cope with the COVID-19 pandemic. In that semester, we went to entirely virtual lecture,…

One of the main courses that have been affected by instructional technology is science education since the nature of topics covered by the science curriculum may require the usage of technology to teach them better. The aim of the current study was to investigate the effects of virtual laboratories on the development of gifted children's…

A large-enrollment, introductory physics laboratory course at the University of Colorado Boulder has undergone a recent transformation to help students' develop lab skills and better align students' views and beliefs about experimental physics with those of expert experimental physicists through engagement with authentic scientific practices. We…

In this study, we focused on students' intrinsic motivation towards practical work, more specifically the strength of predictors for intrinsic motivation. As a research tool, we used a modified Intrinsic Motivation Inventory supplemented by additional questions on attitudes towards physics. The respondents were more than 2000 Czech upper secondary…

An increase in online science course offerings requires a closer evaluation of the online laboratory experience. While it has been established that students can successfully learn from online laboratory simulations, there is a lack of knowledge regarding factors that impact student success. Grounded in the constructivist learning theory, a unique…

Background: Recent studies have highlighted the application of STEM (Science, Technology, Engineering, and Mathematics) knowledge into daily life via hands-on practical works. The limitations of the existing conventional laboratory work can be potentially overcome by the implementation of the innovative use of smartphones as an experimental tool…

In the future, learning will be essentially characterized by the ability to regulate the learning process and monitor success independently from a teacher. The technical possibilities offer better access to learning contents, precise and more individualized feedback, and learning phases adapted precisely to the needs of the learner in terms of…
