This study aims to examine the effectiveness of online problem-based learning (PBL) tasks on problem-solving ability (PSA) and programming skills of secondary school students. A quantitative research design of a quasi-experimental research was adopted in this study. A purposive non-random sampling method was used to select two schools. Then, a…

Understanding existing gender differences in the development of computational thinking skills is increasingly important for gaining valuable insights into bridging the gender gap. However, there are few studies to date that have examined gender differences based on the learning process in a realistic classroom context. In this work, we aim to…

Previous studies have emphasised that play can promote children's learning of mathematics. However, little research has been directed towards understanding how collective imaginary play motivates children's mathematical learning. Informed by the cultural-historical conception of play and motives, this paper examines how Conceptual PlayWorld (CPW)…

The process of diffusion is intimately related to random molecular displacement and is central to many problems in chemistry. Here, we provide an intuitive derivation of the diffusion equation based on the analysis of the random trajectories of particles generated and plotted by simple MATLAB and Python scripts. The codes are very simple and…

The carbonyl group of an aldehyde or ketone reacts with different types of nucleophiles through a nucleophilic addition reaction. When the nucleophile is water, the product obtained is a "gem"-diol or geminal diol. This functionalization is unstable and quickly reverts to the parent carbonyl group. The chemistry of "gem"-diols…

This article investigates the incorporation of loose parts as a means to enhance student creativity within educational environments. Loose parts refer to flexible, movable objects that can be manipulated, combined, and repurposed in various ways. The study delves into the theoretical underpinnings that support the connection between loose parts…

Corrosion of metal, especially iron, is a natural electrochemical process that costs billions of dollars every year. Educating college and precollege students, our future STEM professionals, about the chemistry that governs corrosion and its prevention strategies is of paramount importance. In this manuscript, we share a few simple iron…

For students to gain the most out of education, they need to form long-term memories from experiences gained through active learning. The greatest distinction between active learning and traditional approaches involves the types of tasks and problems the students are challenged to solve. Active learning activities should be structured with student…

When students graduate, they cannot rely on educators telling them if their work is good enough. To do so, they need well-developed evaluative judgement, the capability to make decisions about the quality of their own and the work of others. There is little evidence about the specific approaches that can develop evaluative judgement--or how to…

Although students rely on social solidarity in their everyday lives, they generally fail to acknowledge its existence. An active learning class exercise, conducted within approximately 35 minutes, introduces sociology students to Emile Durkheim's concept of solidarity and the distinction between its mechanical and organic forms. Some groups of…

Algorithms are the essence of computational thinking, which refers to a set of problem-solving processes that help children become logical thinkers in this increasingly digital society. It is important for teachers of young children to carefully plan and implement algorithm design tasks that involve repeated step-by-step procedures to build strong…

For feedback processes to be effective, they need to involve students actively in generating, processing and responding to feedback information. Teacher transmission approaches are unlikely to provide a good investment of time and resources because they fail to draw sufficiently on student agency. In this conceptual article, it is argued that…

This research was conducted to determine the effect of activities carried out at a project on teachers' awareness about out-of-school learning. In line with this purpose, a science center was designated as an out-of-school learning setting and 24 science teachers were trained accordingly. Practical studies have been carried out on developing…

As leadership coaches, Kendall Zoller and Antonia Issa Lahera has worked with diverse groups of students. As they have pursued a path of equity for all students, teachers, families, and communities, they have developed a framework to develop, nurture, and grow collaborative relationships. They call it HeartSpace (Lahera & Zoller, 2021).…

Computational modeling and thinking skill sets were previously relegated to computer scientists and programmers. As a result, computational tools are largely unfamiliar to K-12 science teachers and students. Using Mathematical and Computational Thinking and Developing and Using Models were included in the "Next Generation Science…
