DNA-functionalized gold nanoparticles (DNA-AuNPs) have become a popular science theme since their invention in 1990s. They impact our daily lives by playing key roles in rapidly identifying and quantifying important analytes, and are a well-suited chemistry course content for beginners of chemical research. While the salt-aging method represents…

Critiquing journal articles can be intimidating, especially for new scholars. Many new graduate students focus on the findings and discussion rather than the quality of the research. This methodology review guide is our tool to help scholars identify and evaluate a research article, particularly focusing on the methodology. Although there are some…

The role of research ethics committees, and research ethics issues more broadly are often not viewed in the context of the development of scientific methods and the academic community. This topic piece seeks to redress this gap. I begin with a brief outline of the changes we experience within the social sciences before exploring in more detail…

The helium-plasma (HePI) ionization mass spectrometry method was used to track the formation of reaction products and consumption of reactants by continually monitoring the vapors in the reaction headspace in real time. Two examples of the application procedure are presented here: a nucleophilic acyl substitution reaction and a 1,4-nucleophilic…

The discovery of ferrocene, Fe(C[subscript 5]H[subscript 5])[subscript 2], in the 1950s sparked the development of organometallic chemistry including metallocene compounds. Shortly after the isolation of ferrocene, the analogous ruthenium and osmium compounds were discovered. The preparation of ferrocene is common in undergraduate inorganic…

Science is an ethical community whose practitioners aim to discover information about the natural world and to explain discernible patterns that might be detected. Those who pursue science generally embrace certain epistemic values that help establish the moral boundaries of the community, while the twin pillars of rationality and empiricism serve…

Outreach activities give high school students an opportunity to better understand the techniques and strategies used by researchers. Here is an experience with high school students designed to familiarize them with genetic methodologies. Students have been challenged to discover whether restaurant beef burgers are made with female or male beef.…

This article examines the contribution of scientific phenomenology in design pedagogy through the theoretical relationships between the German art school Staatliches Bauhaus and the most important scientific phenomenological theories of the first half of the twentieth century. After showing the relationships between the Gestalt Theory and the…

A 2 min film clip from the classic movie "Son of Frankenstein" is a surprisingly good illustration of, and introduction to, the scientific method as traditionally formulated. It may be useful in introducing the topic to a large variety of audiences. The text includes a description of the clip's content, questions to elicit student…

Research-based learning (RBL) has been discussed in German higher education teaching and learning since the end of 1960s, having found a revival in the 2000s with considerable federal funding which enabled a creation of a variety of RBL-formats at many universities across disciplines. Within this dynamic development, both the Standing Group on RBL…

In our theoretical and conceptual article, we propose that the application of Niklas Luhmann's sociological systems theory as a difference-theoretical approach to the opening of science unveils an openness paradox. We describe and discuss the general concept of open science as currently proposed by UNESCO and posit that only by accepting the…

It is proposed a network approach for electric circuits simplification, that through a unified systematic procedure allows simplifying circuits of any complexity, and evaluation of the equivalent resistances, capacitors and inductors. Circuits to be simplified are characterized by their nodes, and by the elements of different types (resistances,…

Environmental science classes often ask students to examine changes in species or their environments to determine the human impact on a particular habitat or ecosystem. It is not always practical to take students out for a field study to do this kind of analysis; instead, the scientific method and diversity analyses can be utilized while students…

Data reasoning is an essential component of scientific reasoning, as a component of evidence evaluation. In this paper, we outline a model of scientific data reasoning that describes how data sensemaking underlies data reasoning. Data sensemaking, a relatively automatic process rooted in perceptual mechanisms that summarize large quantities of…

Project-based learning is widely used in organic laboratories. This goal-oriented and inquiry-based learning model complements student-centered training. Such models focus on complicated issues or real-world problems on the frontier of chemistry. Students progress through three project phases: preproject, during the project, and postproject.…
