“…Consequently, educators are increasingly introducing a variety of instructional media and resources to teach the principles of VSEPR. Previous examples include approaches embedding elements of gamification and molecular model building (Erlina et al, 2018), molecular computer modelling and the use of experimental data (Martin et al, 2015;Pfennig & Frock, 1999), and 3D printing technology (Dean et al, 2016).…”

Augmented reality (AR) has the capacity to afford a virtual experience that obviates the reliance on using two-dimensional representations of 3D molecules for teaching stereochemistry to undergraduate students. Using a combination of quantitative instruments and qualitative surveys/interviews, this study explored the relationships between students’ attitudes, perceived cognitive load, spatial ability, and academic performance when engaging in an asynchronous online stereochemistry activity. Our activity was designed using elements of game-based learning, and integrated AR technologies. The control group was provided with a copy of our activity that used two-dimensional drawings, whereas the AR group completed an activity using the AR technologies. For this cohort of students, results indicated significant improvement in academic performance in both the control and AR groups. The introduction of AR technologies did not result in the AR group outperforming the control group. Participants from both groups displayed significant improvements in spatial ability throughout the research period. Further, a moderate correlation (rs = 0.416) between students’ spatial ability and academic performance was found. No significant intergroup differences in the perceived cognitive loads of students were observed. A significant difference was observed on one item of the Intellectual Accessibility subscale of the ASCI (V2), Complicated–Simple. We found no correlation for student attitude or cognitive load with academic performance. The findings of this study provide insights for future AR-related studies to explore the role of spatial ability, student attitude, and cognitive load in learning performance.

WebMO is a web‐based interface for all major quantum chemistry programs. WebMO uses a server–client architecture that installs on a single server or cluster computer and provides access to state‐of‐the‐art computational chemistry programs from a standard web browser. The web interface provides a 3‐D molecular editor, pre‐defined calculations types, job submission and monitoring, visualization of results, and user management tools. Barriers to using state‐of‐the‐art computational chemistry in teaching and research are minimized through WebMO's universal accessibility, its intuitive and uniform interface to all programs, no software to install on client computers, and support for multiple users with a single instance. Applications of WebMO throughout the undergraduate curriculum are provided. The extensible open‐architecture design allows for collaboration among educators, researchers, quantum chemistry program developers, and the WebMO interface developers.

“…However, the correct angle used by the VSEPR Rule is 109.5 degrees. There are many types of instructional media by which students are able to see molecule models three-dimensionally, such as balloons, ball and stick models, three-dimensional molecules in computers [2], and 3D printing models [3]. These create three-dimensional pictures, but there are still some limitations on the assessment of students' understanding.…”

“…Computer software asks students to predict bond angles of molecules and then enter the data in the program. The software allows them to vary and find the right bond angles to receive the energy equal to zero or lowest energy [2]. With 3D printing, six pieces of 3-dimension models are created, like puzzle pieces.…”

There are various types of instructional media related to Valence Shell Electron Pair Repulsion (VSEPR) but there is a lack of diversity of resources devoted to assessment. This research presents an assessment and comparison of students' understanding of VSEPR theory before and after tuition involving the use of the foam molecule model (FMM) and hands-on activities in which students created models that represented 13 molecule shapes. It was found that the molecules that were created correctly before and after tuition were in the system without lone pair electrons (AX 2 ) and the system with lone pair electrons (AX 2 E 2 ). The molecules with which the students had most misconceptions, before and after tuition, were from the system without lone pair electrons (AX 5 ) and the system with lone pair electrons (AX 2 E). These findings suggest that the FMM can be used as an assessment tool to reduce misconceptions about VSEPR theory.
