The modern day is known as the "post-truth" era, characterized by the widespread dissemination of false information, as well as personal opinions and emotions taking precedence over established facts in public decision-making. For students, as future democratically engaged citizens, to make well-informed science-based decisions on…

Even though virtual labs help students learn science content, little is known about how well students can later apply this learning to other contexts or tasks when compared to students who performed physical labs. The goal of this study was to understand how students who perform physical versus virtual labs were able to later apply what they learn…

The Instrumental Analytical Chemistry course, taught in the fifth semester across several programs at the Faculty of Exact Sciences of the National University of La Plata, places a significant emphasis on high-performance liquid chromatography (HPLC). This versatile analytical technique is essential for the separation, identification, and…

This study investigates how preservice science teachers (PSTs) develop and utilize representations in chemistry when they engage in argument-based inquiry environments using the Science Writing Heuristic (SWH) approach. The data-transformation variant of convergent design, which is a particular form of mixed method research, was used in the study.…

Understanding molecular structure is fundamental in chemistry education. However, commercially available molecular model kits are often expensive and are not always present in educational institutions. Here we present "ChemBotCap," an innovative, low-cost, and engaging alternative for modeling simple inorganic and organic molecules using…

Background/purpose: The study aimed to investigate the effectiveness of teaching based on multiple intelligences in acquiring chemical concepts and the ability to explain household chemical phenomena among basic-stage students. Materials/methods: The study employed an experimental method with a quasi-experimental design for two non-equivalent…

This study aims to investigate how students mobilise scientific and socio-political knowledge about climate change in communicative actions directed at the public. It presents a teaching and learning proposal for high school science classes, focusing on critical communication and action in the context of climate change. Grounded in the…

The effectiveness of science problem-based learning (PBL) is highly dependent on individual students' variability. Researchers have shown the need for cognition (NFC) and motivation are significant factors. Despite the acknowledged impact of these constructs, there is a gap in understanding the relationships among NFC, motivation, and learning…

The increase in ecological problems and social and moral conflicts has brought character and value education to the agenda in the 21st century. Socioscientific issues (SSI) that concern society and address ethical and moral issues are recommended as appropriate content to develop character and values within science education. In this systematic…

Biochemistry lecture and lab courses often contain enzyme kinetics as part of the curriculum, but do not regularly focus on interpreting the kinetic constants. Similarly, as we implement course-based undergraduate research experiences in our lab courses, we encourage our students to produce publication-quality images and determine the enzymatic…

Here, we propose a laboratory exercise to quickly determine single nucleotide polymorphisms (SNPs) in human "alcohol dehydrogenase 1B (ADH1B)" and "aldehyde dehydrogenase 2 (ALDH2)" genes involved in alcohol metabolism. In this exercise, two different genotyping methods based on polymerase chain reaction (PCR), namely…

Many academic teachers present data as static graphics in their lectures and courses. However, data structures have become more complex in the last decades, especially in the biomedical disciplines, and interactive graphics can provide a better means to communicate the scientific contents to students. Besides, the technological qualifications of…

Teaching disciplinary literacy in the elementary classroom provides rich potential for bridging the literacy-content divide, building background knowledge, extending learning, and deepening student thinking. This article explores how six elementary teachers tried and tested approaches to embedding literacy in three very different subjects:…

Genetic variation is historically challenging for undergraduate students to master, potentially due to its grounding in both evolution and genetics. Traditionally, student expertise in genetic variation has been evaluated using Key Concepts. However, Cognitive Construals may add to a more nuanced picture of students' developing expertise. Here, we…

The reconstruction of two-dimensional (2D) slices to three-dimensional (3D) digital anatomical models requires technical skills and software that are becoming increasingly important to the modern anatomist, but these skills are rarely taught in undergraduate science classrooms. Furthermore, learning opportunities that allow students to…
