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…

Many aspects of electrochemical education, such as electroanalysis demonstrations, require three-electrode-cell experimental setups. Many researchers and educators use screen-printed electrochemical electrodes, which are miniature and disposable but are relatively expensive and use proprietary fabrication components. The present article describes…

The central dogma of molecular biology describes the transfer of genetic information from nucleic acids to proteins and stipulates that the system cannot work in the reverse direction. As a fundamental principle in biology, the dogma is as influential as it is controversial. Some commentators have debated the central dogma's empirical accuracy…

Instructional practices in science education often create dichotomies of "expert" and "outsider" that produce distinct power differences in classrooms. Building upon the idea of "making present practice" to disrupt these binaries, this paper presents select findings from a year-long study investigating two urban…

In the last decade, video games became a common vehicle for citizen science initiatives in life science, allowing participants to contribute to real scientific data analysis while learning about it. Since 2010, our scientific discovery game (SDG) Phylo enlists participants in comparative genomic data analysis. It is frequently used as a learning…

The focus of this case study is the question, 'How can research integrity be taught in higher education?' I will share my experience of teaching this topic over the past three years, organising the various dimensions of research integrity under the broader theme of integrity in science, specifically in terms of norms, functions, and unity. Norms…

This study seeks to elucidate the fundamental principles underlying the hydration, hydrolysis, and enolization of [beta]-diketones, aiming to enhance students' comprehension of the link between fundamental chemical principles and the practical implications of keto-enol tautomerization and diketone-gem diol equilibrium in diverse chemical…

In educational research, there is the general trade-off that empirical evidence should be generalizable to be applicable across contexts; at the same time, empirical evidence should be as specific as possible to be localizable in subject-specific educational interventions to successfully transfer the empirical evidence to educational practice.…

Transcription is the critical first step in expressing a gene, during which an RNA polymerase (RNAP) synthesizes an RNA copy of one strand of the DNA that encodes a gene. Here we describe a laboratory experiment that uses a single assay to probe two important steps in transcription: (1) RNAP binding to DNA, and (2) the transcriptional activity of…

The central argument of this article is that abduction as a "mode of inference" is a key element in the nature of scientists' science and should consequently be introduced in school science. Abduction generally understood as generation and selection of hypotheses permits to articulate the classical scientific contexts of discovery and…

Undergraduate students enrolled in ecology courses read peer-reviewed, scientific literature to learn how hypotheses are tested and to understand conclusions from research. This technical material can be difficult to understand for many students, thus inhibiting learning processes and reducing interest in courses or associated content. Using…

The main aims of the present research were to: (1) describe the scientific outputs indexed in the Scopus and Web of Science databases, from now on WoS, regarding the use of comic books as didactic resources in the teaching-learning of the sciences, and; (2) establish the conceptual structure of scientific output regarding the use of comic books as…

In 1900, three botanists claimed they had found regularities in inheritance, which soon would be known as Mendel's Laws, without knowing the work of Gregor Mendel or of each other. Their claims of independent (re)discovery have been thoroughly studied during the past decades, with various outcomes. The case is still of interest today as it offers…

The worldwide impact of the COVID-19 pandemic has been enormous. It has affected the justification of the contributions from academia, and resulted in rapid spreading of misinformation and conspiracy theories. The use of the social media has during the pandemic intermixed the space between the private and the public domain, and has interfered with…

Increasing diversity in science, technology, engineering, and math (STEM) and STEM-related degrees and professions is a national priority. Research on students' pathways in STEM may contribute to our understanding of how to change institutions to achieve diversity; however, until recently, the dominant narrative invoked a "pipeline"…
