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 aims to develop and validate a Constructivist Learning Environment Model to address secondary students' misconceptions in learning Science. Employing a Design and Development approach (Richey & Klein, 2007), the research is conducted in two phases. Phase 1 focuses on model design, drawing from an extensive literature review to…

Embryology is an essential component to understanding human anatomy. It requires an in-depth understanding of 3D knowledge but is primarily taught with 2-dimensional resources. In particular, the development of the human heart is a complex process and difficult to understand using traditional teaching methods. We present here a series of heart…

Micropaleontology is a critical tool for determining the ages of geologic records, reconstructing ancient environments, and monitoring modern ecosystem health. However, most students are not exposed to micropaleontology in their college coursework. To enable non-expert instructors to integrate microfossil identification training in their…

Students' success in physics problem-solving extends beyond conceptual knowledge of physics, relying significantly on their mathematics skills. Understanding the specific contributions of different mathematics skills to physics problem-solving can offer valuable insights for enhancing physics education. Yet such studies are rare, particularly at…

The aim of this study was to identify students' motivational beliefs in science and revealed the connections between the profiles and three cognitive dimensions of science achievement through the examination of the socio-economic status (SES) and gender covariates of the profile memberships. Latent profile analysis using science motivational…

Teaching the three-dimensional structure of saccharides has consistently been a challenging aspect of organic chemistry courses, impeding students' ability to grasp more advanced topics in biochemistry and food chemistry. In this article, we designed and developed a novel d-glucopyranose model using 3D printing technology for the first time. This…

Purpose: This study examined science achievement; science vocabulary knowledge; and the relationship between science vocabulary, language skills, and science achievement in school-age children with language/literacy disorders (LLDs) and typical language development (TD). Method: Thirty-nine sixth graders (11 with LLDs) completed standardized…

Genetics is an important area of biology that deals with the study of genes and their behaviour. It also explores variations and heredity in living things. Understanding it helps us diagnose and treat diseases, prosecute criminals and improve crops and animal species. However, studies have indicated that students' achievement in genetics is low, a…

This study aims to investigate the effects of inquiry-based learning with peer-assisted technique on sixth grade students. Achievement and learning satisfaction towards inquiry-based learning with peer-assisted technique on sixth grade students were investigate. The participants used in this research were 32 sixth grade students from the second…

The "Vision and Change in Undergraduate Biology Education" report establishes a set of five core concepts that students should build an understanding of throughout college biology programs. While student conceptual understanding is well studied in 4-year contexts, there are minimal studies in community college contexts. Community…

The purposes of the study were to examine the effectiveness of small-scale chemistry laboratory kits on chemistry preservice teachers' teaching competencies and to examine the effectiveness of small-scale chemistry laboratory kits on learners' science competencies. The target group consisted of (1) 20 fourth-year preservice chemistry teachers who…

This study was aimed at improving the creative thinking and problem-solving skills of prospective teachers and to identify the relationship between those skills during science learning using the Ethno-STEAM approach. The quantitative study was carried out with a pre-experimental design. The research design was a one-shot case study. The research…

This study explores the intersection of human intelligence and Artificial Intelligence (AI) to design knowledge-in-use science assessments for supporting students' deep science learning. In the context of evolving educational paradigms, it seeks to harness AI tools (GPT), to enhance knowledge-in-use assessment design, ensuring equitable…

Grit, a non-cognitive skill that indicates perseverance and passion for long-term goals, has been shown to predict academic achievement. This paper provides evidence that grit also predicts student outcomes during the challenging period of the COVID-19 pandemic. We use a unique dataset from a digital learning platform in the United Arab Emirates…
