Imagine handing out assessments that spark enthusiasm rather than dread. In six easy-to-follow steps, this book empowers science teachers to create tasks that guide students to use their knowledge, not just memorize facts. The NGSA design process transforms assessments into valuable classroom tools that teachers can use to chart how students'…

Physically active learning is considered to enhance learning and additionally addresses health goals like increasing activity levels and reducing obesity. However, physically active learning has rarely been applied to science and engineering learning, or utilized with younger learners (e.g under sevens). This article describes a physically active…

Helping students to understand complex processes is one of the core challenges in teaching biology courses. Concept mapping is a flexible pedagogical method that enables students to learn the complexities of a given subject while at the same time being versatile enough that instructors can easily pivot between instructional modalities and/or…

The purpose of this study is to examine the understanding levels of pre-service science teachers related to the concept of electric field within the framework of procedural and conceptual knowledge. The examination questions and the pre-service science teachers' answer sheets are used as data. The questions are analysed according to PCK…

Research Findings: Grounded on personification storytelling, this intervention study introduced a science program including extensive astronomy concepts to 24 children (4-5 years). The storytelling attributes personal characteristics to cosmic bodies with metaphors relating to children's lives in explaining the scientific concepts, for example,…

Background: Engagement with particle-level simulations can help students visualize the motion and interactions of gas particles, thus helping them develop a more scientifically accurate mental model. Such engagement outside of class prior to formal instruction can help meet the needs of students from diverse backgrounds and provide instructors…

Using a joystick module, we followed the movement of a chaotic magnetic pendulum. The pendulum bar was attached to a joystick that served as a pivot point and biaxial angular motion sensor. Using an Arduino board, we could follow the position as a function of time along both the "x" and "y"-axis and draw a graph showing the…

The learning approach is an important component of education. ADI learning model allows learners to argue actively based on the surrounding observable phenomena in the laboratory. This research aims to review national diversities that represent or contribute to studies by applying the ADI learning model and the research type varieties and…

The bromination of six isomeric alcohols is adapted to a discovery-based organic chemistry laboratory experiment, whereby students are provided an alcohol starting material and are charged with determining the product or product mixture produced using relevant spectroscopic data. The experiment solidifies NMR analysis skills while reinforcing the…

Conceptual teaching was developed three decades ago as an alternative to conventional teaching approaches. It promised a significant shift in teaching practices across different disciplines and age groups. Traditionally, science subjects in high school tend to be content-heavy. Teaching science, especially biology, is still rooted in teaching…

We have developed a new foundation-level course at our institution that links the concept of chemical equilibria from four of the traditional subdisciplines (analytical, biochemistry, inorganic, and physical). The course, entitled Solution and Solid State Chemistry (CHEM 210), is designed to serve our chemistry and biochemistry majors, as well as…

This work presents a simple protocol that demonstrates the use of an inexpensive household carbon monoxide detector as a useful tool to detect the release of carbon monoxide gas from thermal cheletropic decarbonylation reactions. The carbon monoxide detection method described has been employed in a short series of reactions used in a university…

We often say food and fuels "contain" energy. It is more accurate to say that energy is stored in the "fuel-oxygen system" generated during photosynthesis. It is definitely "not" stored in fuels or food (except for the very small amount of energy that can be obtained during anaerobic respiration). Aerobic respiration…

We propose an apparatus that emulates the experiment used by Geiger and Marsden in 1913 to investigate alpha particles (Rutherford) scattering. Using a widely available fused deposition modelling 3D-printer, we built a compartmented and easily assembled educational instrument. The whole apparatus is composed of a 3D-printed chamber and an…

In this article, we present a qualitative study examining students' thoughts and strategies while transferring concepts about energy in physics. We include theoretical approaches of existing transfer research and findings from think-aloud interviews with 20 students of different ages and school levels to develop a framework for analysing the…
