Students' problems in understanding of the hybridization process need to be overcome by using interactive media. Therefore, this study aimed to analyze the results of the validation test and the feasibility test of learning media based on Augmented Reality (AR) on the concept of hybridization. The research method used was the Design-based Research (DBR) method based on technology that supports the learning process within two stages, namely the analysis stage and the design and development stage. Data collecting instruments used were a validation test questionnaire and a limited trial sheet. The media was validated by 3 expert lecturers and 10 respondents of Chemical Education Department students at UIN Sunan Gunung Djati Bandung, Indonesia. Overall validation test results obtained an average value of robserved of 0.88. The validation test obtained a value above 0.30, which showed that the learning media was valid and can be used for the limited trial. The limited trial obtained an average value of 88.59 % within a feasible category. This research concluded that AR learning media on the concept of hybridization is appropriate to be used as teaching material in the learning.

“…Therefore, teaching resources that utilize three-dimensional printing is an emerging topic. Specifically, within the fields of crystallography and chemistry, there are recent papers on the production of tangible models of crystals (Casas & Estop, 2015), unit cells (Moeck et al, 2014;Rodenbough et al, 2015), and atoms, molecules, bonds and orbitals (Griffith et al, 2016;Paukstelis, 2018;Smiar & Mendez, 2016). The present paper enhances the list of three-dimensional printing teaching resources that pertain to crystal optics.…”

Crystal optics is an essential topic in mineralogy and is also relevant at postgraduate level in solid-state chemistry and physics. The emergence of lowcost three-dimensional-printing technologies makes possible the creation of tangible objects for multiple educational purposes. Within the field of crystallography and chemistry, some examples of applications of such educational objects have been recently published. These were intended for teaching and learning of crystal and molecular symmetry concepts. In this paper, three-dimensional-printing applications have been extended to crystal optics. A number of tangible models of optical indicatrices have been designed and printed. These models were conceived as dissection puzzles and allow students to actively work on assembling them and analyzing their geometrical features and relevant sections. The STL files of the presented models are made available with this paper.

“…This new generation of molecular models goes beyond the modeling kits that are ubiquitous in science classrooms everywhere. Using 3D printing, researchers have created personalized models to describe proteins, DNA, hybridization, crystal unit cells, nanostructures, complex orbitals, steric interactions, and even models of potential energy surface, among other topics. Despite the utility of these new models, the relatively slow extrusion rate of the current technology means that models can take from several minutes up to hours to complete necessitating the production of models occur outside of normal class times.…”

Development of three-dimensional (3D) printing technology has started a new chapter for in-classroom modeling of chemical molecules. The technology provides the opportunity to design and produce various types of personalized models.However, using classical 3D printers is time consuming, and it is hard to involve students in the modeling process during traditional class times. One solution can be using hand-held 3D printers (3D pens) that allow users to instantly draw geometrical structures. Unfortunately, drawing directly in 3D is very difficult, and precise modeling of even small molecules is simply not possible. In this article, a new approach to 3D modeling is described. It is based on 3D templates that enable the drawing of molecular models directly in three dimensions. The modular nature of the templates allows for the creation of a wide variety of structures. The resulting models provide an accurate representation of molecules including correct bond angles and geometry. This approach makes 3D pens a powerful tool for the modeling of chemical structures.
