This study investigated how different learning tasks influence students' collaborative interactions in immersive Virtual Reality (iVR). A set of chemistry learning activities was designed with iVR, and 35 pairs of undergraduate students went through the activities. Videos of students' interactions were analysed to identify patterns in students'…

Performing HPLC-based experiments in the undergraduate practical classroom is difficult because of the time required to perform an analysis. This limits the type of practical to one that undertakes a simple quantitative analysis. However, with the use of sophisticated simulators, such as the one employed in this exercise, more complex experiments…

Natural sciences can be difficult to grasp because physical and chemical phenomena can take place across time and length scales that are beyond the reach of human perception. This problem is particularly true for students attempting to learn about microfluidics, a discipline that involves intricate engineering methods and fluid phenomena that are…

The study aimed to investigate the effect of computer simulation and animation-integrated instruction on preservice science teacher trainees' conceptual understanding and retention of acid-base chemistry and stoichiometry. A quantitative approach with a pretest-posttest-delayed test quasi-experimental design was used. In the study area, there were…

Guided by the 5E framework (Engage, Explore, Explain, Elaborate, Evaluate), a buffer solution courseware was designed using "Articulate Rise," a content authoring tool. It was deployed in a freshman general chemistry course in the April semesters of 2022 and 2023. The courseware was a supplementary resource to support instructor-created…

The ability to express scientific concepts in mathematical terms and integrate scientific and mathematical reasoning about a phenomenon is a foundational cognitive process involved in scientific thinking. This process called "blended math-science sensemaking" (MSS) is a desired skill for all science, technology, engineering, and math…

Virtual laboratories (VL) can provide students with learning experiences simulating practical experiments in a traditional laboratory. Evidence is presented that students believe in the truth of results from the VL as well as those from the traditional laboratory. The underlying reasons for these beliefs are explored, through Russell's description…

Theoretical and practical foundations of basic electrochemical concepts of heterogeneous charge transfer reactions that underline electrochemical processes are presented for their detailed study by undergraduate and postgraduate students. Several simple methods for calculating key variables, such as the half-wave potential, limiting current, and…

An ICP-MS simulation was developed to support the teaching of inductively coupled plasma-mass spectrometry. The app enables students to conduct the quantification of selenium in a nutritional supplement, monitor the uptake of metallodrugs by cells, and perform qualitative analysis of gunshot residue. The experiments teach a range of analytical…

Understanding the physicochemical properties of organic compounds with potential biological uses is central in current research topics. Thus, students must pursue the integration of different fields of chemistry to obtain and understand the physicochemical parameters that characterize the mechanism of action of key organics compounds. This…

The present technology report is aimed at demonstrating how the implementation of VR chemistry simulations of atomic structure enhances learning among students. MEL Chemistry VR lessons were incorporated into the classroom for 43 first-year undergraduate ITMO University students. The visualization techniques provided the learners with two…

In recent years, chemistry educators are increasingly adopting immersive virtual reality (IVR) technology to help learners visualise molecular interactions. However, educational studies on IVR mostly investigated its usability and user perceptions leaving out its impact on improving conceptual understanding. If they evaluated students' knowledge…

Despite the growing importance of nanomaterials in numerous industries, most undergraduate chemistry students are unlikely to encounter characterization techniques common in the field during their education. Scanning electron microscopy (SEM) is a common technique for materials characterization widely used in careers chemistry students are likely…

A set of web-based stereochemistry tools which help students use virtual 3D models to translate Newman projections and chair conformations and assign "R/S" labels to stereocenters from 2D dashed-wedged structures is described. These tools are unique in the way they link 2D dashed-wedged structures to 3D models to help students develop…

The 21st century technology has advanced to become an accessible beacon of education. The physical boundaries of the chemistry laboratory have expanded with the use of innovative virtual lab simulations despite disparate results from previous investigations of student performance comparing virtual lab simulations with traditional laboratory…
