In the United States with the Next Generation Science Standards (NGSS)'s emphasis on learning science while doing science, laboratory activities in the secondary school chemistry continues to be an important component of a strong curriculum. Laboratory equipment and consumable materials create a unique expense which chemistry teachers and schools…

It was planned to introduce online pre-laboratory session activities to a first-year undergraduate physics laboratory course to encourage a minimum level of student preparation for experiments outside the laboratory environment. A group of 16 and 17 year old laboratory work-experience students were tasked to define and design a pre-laboratory…

As a fundamental strategy for all science curriculum, inquiry is of prime importance. In order to facilitate inquiry during science education in middle school, 5E learning model was applied in this study. Following 5E learning model during a lesson, students can engage in a topic after being served to mitigate cognitive disequilibrium or familiar…

Understanding how scientific conclusions are drawn from data is central to learning about the nature of science. Many students struggle with aspects of reasoning from data, including identifying relationships among variables, interpreting graphs, coordinating theory and evidence, and not allowing personal beliefs to outweigh the data when forming…

Identification and quantification of an unknown illicit drug (cocaine) from both simulated drug paraphernalia and simulated urine can be achieved via direct analysis in real time (DART) triple quadrupole linear ion trap (QTRAP) mass spectrometry (MS). We describe a novel, hands-on laboratory activity which utilizes the recent DART technology…

This paper describes a laboratory exercise that provides students enrolled in introductory nanotechnology courses with an opportunity to synthesize polymer structures with micro- and nanoscale dimensions. Polyvinylpyrrolidone (PVP) films deposited on corrugated PDMS stamps using student-built spin coaters were transferred to clean, dry substrates…

The procedure of a physical chemistry experiment for university students must be designed in a way that the accuracy and precision of the measurements is properly maintained. However, in many cases, that requires costly and sophisticated equipment not readily available in developing countries. A simple, low-cost experiment to determine isobaric…

Significant changes in the teaching-learning process have occurred since the appearance of the COVID-19 pandemic caused by the SARS-CoV 2 coronavirus, due to the limited mobility and closure of university education centers. In this context, essential challenges were presented for teachers and students to finish the academic courses by addressing…

Science-related competencies are demanded in many fields, but attracting more students to scientific educations remains a challenge. This paper uses two studies to investigate the value of using Immersive Virtual Reality (IVR) laboratory simulations in science education. In Study 1, 99 (52 male, 47 female) seventh (49) and eighth (50) grade…

Anticipated learning outcomes (LOs) were defined and used for the backward design of a Course-based Undergraduate Research Experience (CURE). These LOs reflect the inquiry-based nature of CUREs and capture key knowledge and skills inherent to scientific practice and essential in research. The LOs were used to plan a formative and summative…

This study aimed at investigating the effectiveness of using Radioactivity Remote Laboratory Activities (RRLAs) in enhancing Form Four (equivalent to Grade 10) students' understanding of radioactivity and motivation to learn science. For this purpose, in this study, a repeated measures one-way ANOVA design was utilized in which 54 Form Four…

The purposes of this study were to determine pre-service physics teachers' TPCK related to Calculator-Based Laboratory and to examine influences of some contextual factors on their TPCK. This research was based on the transformative model of TPCK that conceptualizes TPCK as a unique body of knowledge. Multiple case study design was used. Both…

This article reports on the introduction of a simple, portable, low-cost, and hands-on spectral tool for first-year chemistry students to use inside the laboratory and its spontaneous dissemination outside of the laboratory. The Mini Spec is a refinement of the Schwabacher minispectroscope in terms of simplicity and language load on the students.…

"Beer Brewing: Chemical and Biochemical Principles" is a 15 week laboratory and lecture course specifically designed for nonscience majors as an introduction to science literacy via structured laboratory experiments that encourage student engagement. It provides students with a foundation in chemical and biochemical principles using a…

Educators around the world have been challenged to adapt their teaching and pastoral care rapidly in response to the coronavirus pandemic. In this article, we, the academic members of the Chemistry Education and Communication Research Theme (CECR) from the School of Chemistry at the University of Sydney, reflect on the challenges and successes…
