In recent years, the trend in science education is toward scientific processes rather than scientific knowledge. An effective science education not only requires the active involvement of students in scientific investigations, but also the development of engagement in discussions about scientific and social issues. To develop students' discussion…

This paper entitled as "Impact of E-Content on Learning Chemistry at Higher Secondary Level" is tried to test the impact of the multimedia courseware in studying chemistry at the XI standard level by picking a sample of 40 students by containing 20 each with control and experimental group by adopting pre-test and post-test control group…

This is the third special issue of "Primary Science," and it is one that offers primary school teachers an insight into an initiative that does wonders for primary science leadership, learning and teaching -- the Primary Science Quality Mark (PSQM). In this article, Shaun Wingrove describes the transformation from dull to shiny science…

The paper is framed within a broader research programme aimed at investigating how science education can enhance the formation of what we call future-scaffolding skills: the abilities to construct visions of the future that support possible ways of acting in the present with one's eye on the horizon. To this end, we designed a module (targeted at…

The generation of secondary colors in digital devices by means of the additive red, green, and blue color model (RGB) can be a valuable way to introduce students to the basics of spectroscopy. This work has been focused on the spectral separation of secondary colors of light emitted by a computer screen into red, green, and blue bands, and how the…

The mass-approach in higher education promotes the broadening of students' number and diversity therefore the question about the young people's readiness to adapt to studies becomes more and more topical. Students who enrol in the natural science faculties of the University of Latvia (UL) are motivated and have high assessment in biology and…

The American Association for the Advancement of Science (AAAS) has outlined four themes that define science literacy; these are systems, models, constancy and change, and scale. More recently, the National Research Council has released the framework for K-12 science education that includes "Scale, Proportion, and Quantity". Scale…

In this article, Regine Haardörfer outlines five general steps taken by good data analysts and how they need to be theory-driven data-informed. She uses these to discuss some issues and propose approaches to promote better data analysis and reporting. The proposed steps to rigorous data analysis are to: (1) create an a priori data analysis plan;…

The action of hammering a nail into wood is examined in terms of the force, momentum and energy required. Some unexpected experimental results are also presented.

This paper presents a new way to demonstrate the principle behind mirages in air in the lab. The setup is simple and includes a modified laser illuminator that allows direct comparison between the deflected light rays and their straight path.

A laboratory experiment for the determination of the cross-linking density of silicone elastomers is described on the basis of swelling experiments and mechanical tests. In the experiment, the macroscopic swelling and mechanical behaviors of the elastomers were discussed as a function of the cross-linking density, which can be easily controlled by…

College physics textbooks (algebra based) tend to shy away from topics that are usually thought to require calculus. I suspect that most students are just as happy to avoid these topics. Occasionally, I encounter students who are not so easily satisfied, and have found it useful to maintain a storehouse of non-calculus solutions for some common…

One theme that both the American Association for the Advancement of Science (AAAS) and the National Research Council (NRC) agree pervades any science course (and specifically chemistry) is scale. Despite the fact that scale concepts and skills are at the core of a student's scientific literacy, scale or the skills related to understanding quantity…

This laboratory experiment introduces students to an important reaction in biomass valorization and allows them to gain a practical understanding of green chemistry. Acid-catalyzed dehydration reactions of fructose to 5-hydroxymethylfurfural and thus humins were performed both with and without aqueous solvent, along with two different catalysts…

It is widely argued that the skills of scientific expertise are tacit, meaning that they are difficult to study. In this essay, I draw on work from the philosophy of action about the nature of skills to show that there is another access point for the study of skills--namely, skill transmission in science education. I will begin by outlining…
