Retention of students' attention in general chemistry courses stands as one of the main challenges that educators are facing in classes of any size and is especially prevalent with classes composed of mixed majors. Herein, we describe our experience with introducing short, 10 min student lectures ("flash talks") on popular chemistry…

A laboratory experiment was developed to introduce systems thinking and green chemistry concepts through the synthesis of the antidepressant and smoking cessation aid, bupropion hydrochloride. The traditional synthesis has several issues from a green chemistry perspective: it uses the toxic solvents N-methylpyrrolidinone (NMP) and dichloromethane…

Instrumentation plays a critical, ubiquitous role in modern chemistry. The undergraduate chemistry curriculum must therefore cultivate students' ability to investigate chemical phenomena via relevant instruments. The instructional laboratory serves as the primary context in which undergraduates learn about instrumentation, where use of instruments…

Catalysis and catalytic cycles are widely used in both research and industry. The addition of a catalysis experiment into the undergraduate laboratory curriculum is important and necessary training to expand student learning. Here, an experiment demonstrating iron-based tandem catalysis was developed and implemented in an organic chemistry course…

An educational lattice model is proposed for the investigation of the influence of the density and indirectly of the pressure on the chemical equilibrium of the ideal gas phase reaction A [equilibrium] 2B. The model can be introduced by a board game simulating a stochastic process. This game can also be used to set up a corresponding computer…

The focus in teaching and research is shifting from a traditional perspective of information literacy (IL) as a specific set of general, mostly text-based skills to a more comprehensive understanding of the complex aspects that constitute IL as an ongoing, context-specific process. However, there is a need for further insight into the social and…

The two-semester General Chemistry laboratory sequence for nonchemistry majors at James Madison University has recently made the transition from expository, confirmation experiments to project-based (first semester) and research-based (second semester) curricula; this narrative will describe the development and current state of the Brewing Science…

To remain globally competitive, education in the United States must focus on retaining students in science, technology, engineering, and mathematics (STEM). As laboratory courses have the potential to be powerful attractors or deterrents to a field, developing effective laboratory pedagogies is important to retain students in STEM. A course-based…

A drug discovery project has been successfully implemented in an advanced undergraduate organic chemistry laboratory. In the laboratory, a five-step synthetic sequence is used to prepare five analogues of 13-phenyl-1-tridecanol. These compounds are key precursors in the synthesis of 2-oxo-14-phenyltetradecanes. This class of compounds, isolated…

To better prepare undergraduate students for current and future biological challenges, scientists, educators and researchers in the Vision and Change report recommended five core conceptual areas essential for the improvement of biological literacy, one of which is biological systems. Systems are an identified core concept that may help promote…

The purpose of this study was to describe students' perceptions of augmented reality learning media in solar system topics. The type of research used was descriptive research. The participants involved in this study were 32 students from class 8C of State Junior High School 3 Sidoarjo, Indonesia. The instruments used consist of a student…

Scientific argumentation skills are a key component of science learning practices needed by students in the 21st century. Where the essence of scientific argumentation is to support the argument with evidence and reasoning and then refute the claims and evidence of the opponent's argument. Supporting arguments with evidence and reasoning can be…

Despite a decline in sexist language, traditional gender beliefs remain embedded in the scientific literature on reproductive biology and consequently continue to distort knowledge, encumber the learning process, and reinforce gender essentialism. This article analyzes the enduring force of gender stereotypes in Italian middle school science…

The purpose of this study is to determine the relationship between Turkish high school students' perceptions of learning environment, conceptions of learning biology and achievement goal orientations. In order to determine the relation among these three sets of variables, canonical correlation analyses were conducted. A total of 398 high school…

The COVID-19 pandemic has introduced challenges to delivering laboratory-based STEM curricula. This study evaluates students' learning experience in a synchronous team design activity within the laboratory component of an undergraduate Computer Engineering course during the pandemic. Using the EduPad digital platform, students collaborated in…
