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.…

In science education, the abstraction and complexity of scientific concepts are usually stumbling blocks that prevent students from learning science. Recently, augmented reality (AR) has offered transformative potential to support scientific concept learning by visualizing scientific phenomena and enhancing students' experiences. However, the lack…

The image of free-falling bar has been recorded to study the effect of the motion on its observed length. This moving bar image is analysed using the Tracker software to determine its length and the end bar's position. An elongated appearance of the bar has been observed with movement. This effect relies on the speed and the exposure time during…

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…

In this work, we report the development of a low-cost Arduino-controlled device for didactic activities in light polarization. The main body of the prototype was designed and produced using laser-cut medium density fibreboard parts, including gears and pulleys. As a light source and detector, a 532 nm laser pointer and a light dependent resistor…

Despite the importance of emotions in science education, research?on affect remains sparse. A promising direction is to explore the role of immersive visualisation in evoking affective responses. We investigate whether touch-based zooming interaction with a tabletop visualisation of the tree of life evokes various affective responses,…

The use of two-dimensional images to teach students about three-dimensional molecules continues to be a prevalent issue in many classrooms. As affordable visualization technologies continue to advance, there has been an increasing interest to utilize novel technology, such as augmented reality (AR), in the development of molecular visualization…

Dimensionality reduction techniques are essential in analyzing large 'omics' datasets in biochemistry and molecular biology. Principal component analysis, t-distributed stochastic neighbor embedding, and uniform manifold approximation and projection are commonly used for data visualization. However, these methods can be challenging for students…

The importance of introducing computational approaches early and actively in science education is widely acknowledged among educators and scientists. Many great ideas have been put forward and implemented by advocates and organizations such as Partnership for Integration of Computation into Undergraduate Physics (https://www.compadre.org/PICUP)…

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…

We present a computer-based experiment that simulates the accretion process and generates fluffy aggregates with fractal nature. The Box Counting is performed without the aid of an image processing tool by using the coordinate information of the constituents of the aggregate. A simple algorithm to create aggregate and calculate box-dimension will…

The video of a free-falling object was analysed in Tracker in order to extract the position and time data. On the basis of these data, the velocity, gravitational potential energy, kinetic energy, and the work done by gravity were obtained. These led to a rather simultaneous validation of the conservation law of energy and the work-energy theorem.…

This three-day integrated 5E inquiry lesson that includes physics, engineering, and biology concepts, uses physical computing and photoplethysmography to learn about one's pulse. The main learning objective is to have students communicate how wave phenomena, like a pulse, can be analyzed using sensors, which is called physical computing. This…

We describe a simple STEM project for students to learn to measure atmospheric pressure by using a sensor of the type BMP180 together with the Arduino electronic platform. The collected experimental data, together with simple experiments, can be used to study the different pressure units and the relationship between pressure and force. Also, they…
