This publication presents a series of experiments in the field of nanomedicine for high school chemistry education and student laboratories, developed as a collaborative project between chemistry didactics and chemical research. In this context, polymeric nanocarriers represent a promising approach for drug delivery, acting as "smart…

The field of DNA nanotechnology has grown rapidly in the past decade and has expanded to multiple laboratories. While lectures in DNA nanotechnology have been introduced in some institutions, laboratory components at the undergraduate level are still lacking. Undergraduate students predominantly learn about DNA nanotechnology through their…

This paper describes the creation of a theme-based first quarter, of a two quarter sequence, general chemistry laboratory course following an argument driven inquiry format and employing specifications grading. The course contains four, two-week projects investigating the chemistry of a popular sports drink. The sugar content, dye concentration,…

Kombucha, a popular probiotic beverage, contains detectable concentrations of ethyl alcohol. To be sold as a nonalcoholic product, alcohol concentrations in kombucha must be shown to be less than 0.5% by volume. This paper describes the use of an inexpensive, commercially available sensor to reliably and accurately measure alcohol concentrations…

Where does science and technology studies (STS) belong? In "A Place for Science and Technology Studies," Jane Calvert takes readers through eight different rooms--the laboratory, the conference room, the classroom, the coffee room, the art studio, the bioethics building, the policy room, and the ivory tower--investigating the…

The Meaningful Learning in the Laboratory Instrument (MLLI) was designed to measure students' expectations before and after their laboratory courses and experiences. Although the MLLI has been used in various studies and laboratory environments to investigate students' cognitive and affective laboratory expectations, the authors of the instrument…

Providing hands-on practical education without access to laboratories during the COVID-19 pandemic has required creativity and innovation. In this paper, co-authored by academic staff and students, we describe an at-home mobile phone-based 'spectrophotometer' experiment used in an introductory undergraduate biology course. Using colour picker…

The under-representation of women in undergraduate science courses is well-documented. One significant challenge is that women may both perceive and receive less recognition from their science peers about their abilities as scientists than men. Here we investigate the presence and nature of such gender biases in peer recognition in the discipline…

An integrated and projected-based laboratory course was described, integrating interconnected knowledge points and biochemistry and molecular biology techniques on a research project-based system. The program, which served as an essential extension of theoretical courses to practice, was conducted with a sophomore of basic medical science who had…

The study investigates students' ability to analyze visual literacy and digital literacy through open-ended inquiry activities with astronomical observations and Heaven View application. The investigation consists of assignments for students to carry out six different variations of observational activities. Supervision is given in introductory…

For nearly two decades, augmented reality (AR) has found diverse applications in education, particularly in science education, where its efficacy has been supported by relevant theories and many empirical studies. However, previous studies have revealed the following research deficit: While AR technology appears to influence learning-related…

By hosting a college students' laboratory skills contest, we provide an interesting activity for students to cultivate good laboratory practices and thereby improve their laboratory skills. The substance of this contest is the detection of the hardness of water, which involves numerous laboratory skills such as solution preparation, weight by…

One step of the published mechanism of the hydrogen peroxide iodine-clock reaction is called into question by the result of an experimental attempt (predicated on that mechanism) to integrate that reaction into the elephant's toothpaste demonstration to reveal and control its iodine side product. Under conditions that were a hybrid of those…

In this paper, we discuss the theory of the operation and some practical considerations for the construction of an air ionization chamber, which can be used as a very simple detector of alpha particles. These detectors have several benefits compared to spinthariscopes and spark detectors. Classical experiments with ionization chamber detectors are…

The COVID-19 pandemic began as a health crisis and quickly turned into an economic, social, and political crisis. It revealed the vulnerability of education systems to external changes and risks and challenged institutions and educators to transform and adapt at short notice. Following the COVID-19 outbreak, one of the natural consequences was the…
