Background: In countries that endorse science, technology, engineering, and mathematics (STEM) education as an educational movement, design-based learning is deemed a pedagogical approach. Purpose: Because the integration of the engineering design process and scientific investigation has been an issue in science education, this study examined the…

In this paper, in order to pursue the conversation begun by Fages and Albe ("Cult Stud Sci Educ" 2014), I highlight three conceptual contributions that could be made by familiarizing nanoscience and nanotechnology researchers and engineers with the work being carried out in science and technology studies and public understanding of…

What we choose to assess in science is what will end up being the focus of instruction. US science standards once treated content and inquiry as fairly separate strands of science learning, with content standards stating what students should know and inquiry standards stating what they should be able to do. In its content coverage, these standards…

Protein engineering is a powerful tool, which correlates protein structure with specific functions, both in applied biotechnology and in basic research. Here, we present a practical teaching course for engineering the green fluorescent protein (GFP) from "Aequorea victoria" by a random mutagenesis strategy using error-prone polymerase…

Chemists continue to work at the forefront of materials science research. Recent advances include application of bioengineering to produce plastics from renewable biomass instead of petroleum, generation of paper-based batteries, and development of phototriggerable microcapsules for chemical delivery. In this article, the author provides summaries…

Discusses the master equation of a stochastic model in chemical process systems. Presents a solution technique known as the System Size Expansion. (YP)

Establishes a theoretical basis for both understanding and testing the molecular level assumptions in mixtures. Considers activity coefficient models and equation of state mixing rules. (YP)

Described are the idea of chaos and the ability to control the chaotic behavior of a real-world physical system. Included is an explanation of the methodology and applications in biology and chemistry. (KR)
