Glycosylation is a biologically significant post-translational modification (PTM) of proteins that involves the covalent attachment of a sugar molecule (a glycan) to a peptide sequence, resulting in the formation of glycoproteins. Glycomics and glycoproteomics involve the complete mapping of glycans of a cell, tissue, or organism.…

This mixed-methods study investigated the effectiveness of Generative AI (GenAI) powered intelligent tutoring systems (ITS) in undergraduate physics education, specifically comparing learning outcomes between students using Khanmigo (Khan Academy's AI tutor) and the Google search engine. The study involved 69 undergraduate students divided into…

Electricity, especially the flow of current, is a challenging topic for students of all ages. This study conceptualizes students' explanation of electric current as a cluster of knowledge elements. These clusters, in turn, represent students' mental models of electric circuits. Thus, this study aims to identify and characterize students' mental…

This study explores multilingual study guidance (MSG) teachers design for learning and the potential of immersive and interactive Virtual Reality (VR) technology to support students' development of disciplinary knowledge through multilingual conceptual learning. Part of a co-design research project, the study draws on two teachers' didactical…

This study aims to design an educational process for teaching scientific concepts during the preschool period based on the instructional design model of Seels and Glasgow and to evaluate its effectiveness. For this purpose, a material set incorporating a teacher's manual and interactive holographic materials was developed. The teacher's manual…

Numerous previous studies have reported the difficulties associated with learning the Brønsted-Lowry acid-base model. The Brønsted-Lowry acid-base model requires complex systems thinking because it considers random interactions between reactant and product particles and effective particle collisions in forward and reverse reactions. The system…

During the periods of sudden transition to online education, the opportunity to make applications that might attract students' attention to the course has decreased even more. Although this deficiency tried to be eliminated with videos and simulations, it was not possible to ensure the active participation of students in some cases. In this study,…

As computational models are becoming more widely used with the release of "A Framework for K-12 Science Education" (NRC 2012) and the "Next Generation Science Standards" ("NGSS"; NGSS Lead States 2013), these models are reshaping the way science is practiced in increasingly diverse classrooms. For students classified…

The integration of information and communication tools in education has been a common trend in the last decade which resulted in increased student engagement, motivation, and even achievement and learning. Despite these improvements, science teachers still report challenges with its use in science education. Several abstract topics in chemistry…

The effect of PowerPoint Presentation-based (PPPb) quiz to the students' scores has been rarely studied. It is the intention of this research to understand the effect of PPPb quiz to students score in wave motion and the students' experiences under such a strategy. This research used a mixed approach: quasi-experimental to learn if scores gain was…

We present a simple activity based on the liquid-drop model which allows secondary school students to explore the uses of mathematical models and gain an intuitive understanding of the concept of binding energy, and in particular the significance of positive binding energy. Using spreadsheets provided as supplementary material, students can…

The BBC Micro:bit is a great device to encourage students to get involved in Computer Science and to create their own digital projects. However, the design of the single-board computer (including the built-in sensors) makes it possible to use it in Physics lessons or in Physics related activities, too. Those students who are keen to take up…

Central to evolution is the concept of a common ancestry from which all life has emerged over immense time scales, but learning and teaching temporal aspects of evolution remain challenging. This study investigated students' interpretation of evolutionary time when engaging with a multi-touch tabletop application called DeepTree, a dynamic…

Computational techniques have great potential to improve the teaching-learning. In this work, we used a computational strategy to visualize three-dimensional (3D) structures of proteins and DNA and help the student to comprehend biochemistry concepts such as protein structure and function, substrate, and inhibitors as well as DNA structural…

In chemistry, novices and experts use mental models to simulate and reason about sub-microscopic processes. Animations are thus important tools for learning in chemistry to convey reaction dynamics and molecular motion. While there are many animations available and studies showing the benefit of learning from animations, there are also limitations…
