The COVID-19 pandemic has changed education. In these circumstances, technology aided learning by providing new ways of teaching and communicating with students. In this work, we report the online activities carried out in the Basic Organic Chemistry virtual course of the Chemistry Department at UNS (Argentina) for first-year students of the…

Students' understanding of the electronic structure of the atom has been investigated by many authors. This study outlines students' conceptual and representational understanding of quantum concepts explored in lower and upper level chemistry courses, in three different chemistry majors, identifying learning obstacles and monitoring student…

Electrophoresis is integral to analytical and biochemistry experiences in undergraduate education; however, fundamental principles of the method are often taught in upper-level laboratories through hands-on experiences. A laboratory activity is reported that teaches the concepts of electrophoretic mobility and electroosmotic flow. A single…

The conceptual change approach has been a prevalent theoretical foundation for comprehending students' acquisition of scientific knowledge. Despite its extensive use, only a limited number of studies have employed this framework to examine the effectiveness of game-based learning (GBL). The GBL was utilized to teach 101 middle school students…

This study examined the effects of science and engineering (S & E) inquiry on preschool and kindergarten children's academic outcomes using a randomized control-group design. Participants were divided into three groups: a classroom-only group (C-only) receiving NGSS-aligned S & E inquiry; a classroom plus family engagement group (C + F)…

The rapid evolution of generative artificial intelligence (GenAI) is transforming science education by facilitating innovative pedagogical paradigms while raising substantial concerns about scholarly integrity. One particularly pressing issue is the growing risk of student use of GenAI tools to outsource assessment tasks, potentially compromising…

One particularly pressing issue is the growing risk of student use of GenAI tools to outsource assessment tasks, potentially compromising…

Learning about redox and electrochemistry in senior secondary school science has long been recognised as both impenetrable to many students and problematic for teachers. A significant barrier to understanding this area of learning has been the apparent exclusive use of implicit analogous definitions for the foundation concept of an oxidation…

This theoretical paper defines and explores the concepts of transductive links and transductive chains, as part of the theoretical framework of social semiotics. Social semiotics stems from the multimodal framework, which provides a theoretical perspective, constructs, and a language to describe a shift of semiotic material within or between…

The process of meiosis is an essential topic that secondary and postsecondary students struggle with. The important meiosis-related concepts of homology, ploidy, and segregation can be described using the DNA Triangle framework, which connects them to the multidimensional nature of DNA (chromosomal, molecular, and informational levels). We have…

In the April 2018 issue of "TPT," Joseph Amato presented an analysis of intercontinental ballistic missile (ICBM) trajectories as applied to recent test launches from North Korea. Using properties of their elliptical paths, he derived relationships between launch velocity, elevation angle, and maximum range. However, this approach cannot…

Descriptive correlational research was conducted to discover misconceptions on Rate of Reaction (RR) that impact on Chemical Equilibrium (CE) misconceptions. This research was conducted to 245 eleventh-grade students of High School in Gowa, South Sulawesi, Indonesia, that having been studied the RR and CE topics. Misconceptions data were collected…

Problem-based learning (PBL) instruction tasks students with solving a real-world, relevant problem and provides a motivating context for learning science content. It also affords a natural opportunity for students to intentionally engage in a variety of engineering practices and components of engineering design if the problem scenario…

Due to the prevalence of pseudoscience, scientific illiteracy, and fake news, scientists are increasingly concerned about pseudoscientific beliefs among individuals without advanced scientific training. We recruited 85 undergraduate participants who read 10 pseudoscientific texts in each of the following conditions: APA-style references,…

An engaging, simple, and cost-effective laboratory experiment has been implemented at our institution to teach undergraduate chemistry students about cyclic voltammetry and electrochemistry in general. This experiment involves the application of cyclic voltammetry to analyze a sample of acetaminophen (APAP) with the objective of determining the…
