Real situations are overlaid with virtual information using augmented reality technology. In a learning environment, this technology could give everyday relevance to abstract concepts. In this paper, we will show how physical structures in typical experiments can be simply augmented by virtual objects in physics classes. This is achieved by…

Writing is an integral part of the process of science. In the undergraduate physics curriculum, the most common place that students engage with scientific writing is in lab classes, typically through lab notebooks, reports, and proposals. There has not been much research on why and how we include writing in physics lab classes, and instructors may…

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…

As the need for online or virtual science courses grows, it is important to incorporate laboratory work into these courses. However, it is difficult to find cost-effective ways to integrate the laboratory work, especially as campuses across the world have had to quickly transition to the online learning environment in the midst of the COVID-19…

We present an experiment designed to hone the decision-making skills of (undergraduate) chemistry students by using aqueous crossed aldol reactions. Here, we present two simple crossed aldol reactions based on inexpensive and readily available materials: The condensation of vanillin and cinnamaldehyde with acetone. The procedure uses the variation…

MEMs gyros, such as those in smartphones allow the angular velocity of pendulums to be precisely measured at large angles, and phase plots of the angular acceleration versus the angular displacement confirm that [double dot][phi] = -[omega][superscript 2][subscript o] sin[phi] even for the non-sinusoidal motion at amplitude [phi][subscript o]…

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 increasing integration of software and automation in modern chemical laboratories prompts special emphasis on two important skills in the chemistry classroom. First, students need to learn the technical skills involved in modern scientific computing and automation. Second, applying these techniques in practice requires effective collaboration…

Purpose: The present study examined the effect of Directed Activity Related to Texts (DARTs) and gender on student achievement in qualitative analysis in chemistry. It focused on the qualitative analysis component of the Chemistry course, which for students has been perceived as being the most difficult aspect of their mastery of the subject.…

The COVID-19 pandemic has forced educational institutions to adjust their learning process to distance education or online learning. This paper explains how to teach optics during the COVID-19 pandemic by implementing project-based learning that can be supervised online. Students are instructed to design, characterize, and optimize droplet lenses…

The practical work described here is designed for third-year bachelor students in Life Sciences attending a kidney physiology course. It illustrates how urinary biochemistry can be used for a medical diagnosis. Students have to measure glucose, proteins, and creatinine concentrations in three simulated urine samples. First, they independently…

Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that has been implemented by the International Association for the Evaluation of Educational Achievement (IEA) since 1995. This proposed study is aimed to identify the correlations of science classroom teachings with eighth graders' science…

The purpose of the study reported on here was to investigate the role of partnerships in helping in-service teachers overcome the difficulties associated with performing practical work prescribed in the Life Sciences Curriculum and Assessment Policy Statement (CAPS), an educational policy intended to transform the South African school curriculum…

Although international school systems and resources can differ from those in the UK, it is always useful to have an informed worldview of practice in primary science. The COVID-19 pandemic has inevitably changed the ways in which pupils around the world have access to knowledge. Furthermore, it has changed the ways in which teachers globally…

It is commonly accepted that learners gain better understanding of science concepts when they perform 'hands-on' experiments in the lab. However, the lack of lab infrastructure, particularly in most rural schools, negatively affects the teaching of science. With the increasing potential of ICT to education, virtual laboratories (VL) have emerged…
