A new method for teaching advanced laboratories at the undergraduate level is presented. The intent of this approach is to get students more engaged in the lab experience and apply critical thinking skills to solve problems. The structure of the lab is problem-based and provides students with a research-like experience. Students read the current…

After seeing several reports in newspapers making claims about the cause of death after children had swallowed button batteries, a team of students decided to try to establish which (if any) claims were true. The findings were reported in the Schools Exhibition at the ASE Annual Conference 2018 in Liverpool and are shared in detail here. (A…

The application of the Reaction Monte Carlo (RxMC) algorithm to standard textbook problems in chemical reaction equilibria is discussed. The RxMC method is a molecular simulation algorithm for studying the equilibrium properties of reactive systems, and therefore provides the opportunity to develop computer-based "experiments" for the…

Manipulative environments play a fundamental role in inquiry-based science learning, yet how they impact learning is not fully understood. In a series of two studies, we develop the argument that manipulative environments (MEs) influence the kind of inquiry behaviors students engage in, and that this influence realizes through the affordances of…

The concept of energy is of central significance, as it is a core disciplinary idea in chemistry and a cross-cutting concept in the sciences. This study sought to investigate student understanding of energetics and associated thermodynamic functions in chemical reactions and processes across a sample of introductory-level undergraduate chemistry…

Biochemistry and molecular techniques are used for the development of the scientific practice of students. To improve both the teaching and learning quality and promote the students' motivation, this article outlines an interactive "Virtual Simulation and Actual Operation Combined" approach by using a tailored virtual practice-learning…

In the last decade, a powerful tool has been given to physics teachers to visualize thermodynamic phenomena. Thermal imaging cameras are fascinating devices opening the world of (even small) temperature changes and being able to uncover hidden manifestations of many processes around us. This paper describes a few qualitative thermal imaging…

This study investigated the management of teaching and assessment of the "qualified to be progressed" learners (QP) for quality learning and teaching. Mixed methods approach was adopted. Random and purposive sampling were used to select teachers and School Management Team (SMT) member respectively who formed the study sample. The study…

Epigenetic inheritance is the inheritance of genetic information that is not based on DNA sequence alone. One type of epigenetic information that has come to the forefront in the last few years is modified DNA bases. The most common modified DNA base in nature is 5-methylcytosine. Herein, we describe a laboratory experiment that combines…

Portions of classic undergraduate quantitative analysis experiments in complexiometric titration and potentiometry are combined with a field-sampling experience to create a two period (2 × 3 h) comparison-based experiment for second-year students. A multifunctional chemical analysis device is used with calcium ion-selective electrode for field…

This laboratory exercise demonstrates the use of an immunoassay for studying kinase enzyme activity in living cells. The advantage over the classical method, in which students have to isolate the enzyme from cell material and measure its activity in vitro, is that enzyme activity is modulated and measured in living cells, providing a more…

Mechanochemical syntheses avoid or considerably reduce the use of reaction solvents, thus providing green chemistry synthetic alternatives that are both environmentally friendly and economically advantageous. The increased solid-state reactivity generated by mechanical energy imparted to the reactants by grinding or milling can offer alternative…

Stoichiometry has always been a puzzling subject. This may be partially due to the way it is introduced to students, with stoichiometric coefficients usually provided in the reaction. If the stoichiometric coefficients are not given, students find it very difficult to solve problems. This article describes a simple 4-h laboratory experiment for…

This manuscript elaborates the value of looking beyond the written and spoken word in science education research and practice at the early childhood level. We examine one plurilingual child's descriptions of a science activity to explore the "diversity of resources" that she used while expressing her understandings of a sound…

"Active learning" has been used to describe classrooms that have varied widely with respect to instructional topics, age of learners, and the procedures used to operationalize the general notion of the term. In most cases, the specific variant of active learning under investigation has been more effective than the particular control used…
