“…A simple and open-source based application named Winplot, has been widely used in the field of educational research. Winplot, which was developed by Richard Parris of the Phillips Exeter Academy, New Hampshire (Shechter, 2016), provides an alternative way to easily plot mathematical equations as useful physical interpretations (Saputra et al, 2015). Some studies have used Winplot to visualize hydrogen atomic orbitals and hybrid orbitals (Chung, 2013;Saputra et al, 2015, Rhile, 2015.…”

“…Jones et al (2005) explain that learning by graphical visualization can significantly help students in understanding the sub-microscopic world. Some studies have been conducted to use computer software to enhance students' understanding of orbitals and quantum numbers (Harvey & Gingold, 2008;Trindade & Fiolhais, 2003;Lang & Kobilnyk, 2009;Chung, 2013;Stewart et al, 2013;Chen et al, 2015;Saputra et al, 2015). For example, Lang & Kobilnyk (2009) used Second Life to visualize atomic orbitals.…”

Misconception is one of the most widely researched topics in science education, including chemical education. This research aims to apply simple graphical visualization tool named Winplot for a learning exercise activity and explore its potency to counter misconceptions about orbitals and quantum numbers. Misconceptions that were countered in this research are the existence of orbitals in atoms and the relationship of magnetic quantum numbers to orbital orientation. This quasi experimental research using pre-test-post-test control group design was conducted to 43 first-year undergraduate students as control class and 45 as experimental class of chemical education at the University of Lampung. The students’ pre-existing concepts were analyzed using a pre-test instrument and explored further using in-depth interview. Then, after implementing a learning exercise activity, the conceptual changes were analyzed using a post-test instrument. The results showed that students in experimental class had significant conceptual changes compared to control class. Applying this computer-based strategy is highly recommended to guide students in understanding chemical concepts, especially the topics of orbitals and quantum numbers. Key words: learning exercise, first-year undergraduate, computer-based learning, misconceptions, quantum chemistry.

“…For example, Rhile 23 has recently pointed out the inaccuracy in representation of sp 3 hybrid orbitals if this incorrect assumption is made. 24 The method proposed in the present work gives students a hands-on way to understand the origin of orbital shapes, which involves both its radial and angular parts.…”

There exist several two-and three-dimensional graphical representations of hydrogen-like orbitals. Despite this, connecting the mathematical form of the atomic orbital, a function of both radial and angular variables, to its actual shape is often challenging for students. Here, we present a new graphical representation using bubble plots to show the combined contribution of the radial and angular parts of the wave function to its shape. This representation can be demonstrated on the blackboard, as well as easily plotted by students. Additionally, it is one step away from contour plots of orbitals, which are commonly used in their depiction.

“…Graphical visualization softwares can be very effective tools in bridging the theoretical aspects of QM and physical phenomena. They can be applied in the classroom as supplements to lectures or outside the class as homework or as self-study tool by students(Saputra et al, 2015;Singh, 2005).…”

Chemistry undergraduate students are required to master the theory of quantum mechanics as the basic requirement to study the properties of the submicroscopic particle. However, many studies showed the students’ difficulties to bring the quantum mechanical concept to the macroscopic world and vise-versa. The use of computer visualization tool will very useful for teaching and learning the quantum concept, especially electron and its related atomic orbitals. This technological report paper demonstrates some of the Android-based applications i.e FuncXY, TriPlot 3D Graphing, and Graphing calculator to effectively, quickly, and accurately convert wave functions into various hydrogen atomic orbital visualizations. By selecting spherical coordinate and entering wave equation, these smartphone graphical devices visualize three-dimensional atomic orbitals. Users are also easy to rotate, zoom and manipulate the object. Finally, these user-friendly plotters are very recommended to assist chemistry educators in teaching quantum mechanics.
