Education in organic chemistry is highly reliant on molecular representations. Students abstract information from representations to make sense of submicroscopic interactions. This study investigates relationships between differing representations: bond-line structures, ball-and-stick, or electrostatic potential maps (EPMs), and predicting partial…

Resonance is a crucial concept in Organic Chemistry that enables both deriving chemical properties from molecular structures and predicting reactions by considering electron density distribution. Despite its importance for problem-solving and learning success, learners encounter various difficulties with this concept. Although prior research…

This qualitative study delves into the intricate landscape of general chemistry students' study strategy decision-making processes, examining the guiding factors that shape their choices. Past work in chemistry education has shown that students' study behaviors are dynamic in nature. Employing self-regulation theory, the study aims to provide a…

The purpose of this qualitative descriptive study was to explore how science students described their experiences of collaboration in a virtual learning environment at a community college in the Midwestern United States between 2020 - 2022. The literature review indicated the need to understand how science students described their experience of…

Text-to-speech (TTS) technology is a common accommodation available for students with disabilities. Despite the ubiquitous nature of TTS, this technology has not been explored in laboratory settings for neurodiverse college students. This study explores the adaptability of laboratory accessible TTS technology (originally developed for blind/low…

The learning of scientific concepts is one of the main research subjects in science education. Although little used, the theory of conceptual profiles allows the study of this knowledge, taking into account the presence of different ways of thinking about a certain concept in the same individual. This study aimed to build a conceptual profile for…

We developed a curriculum for an upper-level molecular biology course-based undergraduate research laboratory class funded by a National Science Foundation CAREER grant that focuses on identifying new small proteins in the bacterium, "Escherichia coli." Our CURE class has been continually offered each semester for the last 10 years, with…

In theory, there is broad agreement among science education stakeholders that supporting the achievement of scientific literacy is crucial for citizens to make informed and critical decisions about socioscientific issues (SSI). Likewise, it is widely held that argumentation is an important component of scientific literacy. In practice, however,…

We here propose a simple and fast hands-on activity requiring limited equipment, to introduce students of various levels (bachelor's or high school) and backgrounds (from science to arts) to the chemistry of color. The different colors of stained glass are replicated through the deposition, on ordinary glass slides, of silica coatings colored by…

Enzymes are organic molecules known for their catalytic nature because they accelerate metabolic reactions in organisms. The study of enzyme functions and modes of action is essential to understand Biochemistry. This study aimed to analyse the acetylcholinesterase enzymatic activity, as well as the enzymatic inhibition mechanism in practical…

This paper seeks to evaluate learning based on the competency approach, taking a didactic experience to evaluate a possible improvement in the ability to solve problems and for autonomous learning in general. For the didactic development, the theme "gases" was taken, which is generally enunciated: Corpuscular kinetic theory of matter;…

A traditional anatomy lab using microscope slides to examine the structures of the integumentary system was enhanced to increase connections to the real world, student engagement, and interest in the topic by adding a forensic storyline where students examined structures of the integument in order to "solve the crime". Student…

We report on an investigation of student thinking about steady-state pipe flow of an incompressible fluid. About 250 undergraduate engineering students were given a test consisting of two hydrodynamics questions, combining multiple-choice format with subsequent open-ended explanations. There is substantial evidence that students have difficulty…

Students in a typical instrumental analysis course may learn more than 30 analytical techniques. There are more than 150 components associated with the instrumentation that they learn. To help students organize this large amount of information, we classified these components into four categories: sources, samples, discriminators, and detectors. In…

Contrary to the situation at primary, middle, and secondary school levels, university science courses provide students with very few opportunities to reflect upon the nature of science (NOS). The first goal of this study was to provide evidence that the co-construction of evolutionary trees, an important component of university biology education,…
