How might you experience the world around you if you were shrunk to the size of an atom?






Particle in a box is a virtual world governed by the laws of Quantum Mechanics that enables you to experience the world of the very small.

College quantum mechanics courses often focus more on the mathematical constructs and less on the qualitative understanding of the subject. Existing visualizations (and very few existing games) for QM are also highly technical, too focused on mathematical formulas, and hard to approach. To tackle this problem, we are exploring supporting material such as interactive visualizations and games for teaching and learning quantum mechanics.

Incorporating an iterative design process, Particle in a Box is a game that combines principles from game design, scientific visualization, and QM physics to create a unique experience that allows players to compare the classical and QM environments and create a virtual environment that engages and habituates students to QM concepts.

Particle In A Box: An Experiential Environment for learning Quantum Mechanics
Aditya Anupam, Ridhima Gupta, Azad Naeemi, Nassim JafariNaimi
IEEE Transactions on Education (Under review)


Abstract
Quantum mechanics (QM) is a foundational subject in many fields of science and engineering. However, it is difficult to teach because it requires a fundamental revision of the assumptions and laws of classical physics and probability. Further, introductory QM courses and texts predominantly focus on the mathematical formulations of the subject and lay less emphasis on its conceptual understanding. Consequently, students struggle to build robust mental models of the concepts. In this paper, it is posited that games can provide an effective platform for an experiential understanding of introductory QM. Games can immerse students in an engaging environment that motivates them to learn. They are also particularly suitable for demonstrating QM characteristics because their repetitive nature is conducive to demonstrating probability concepts that form a core part of QM. This paper presents the design and evaluation of a digital game for learning introductory QM concepts. The evaluation of the game indicates an improvement in students’ conceptual understanding of probability. Students also reported an increase in comfort level with the key concepts taught in the game.

Abstract
Quantum Mechanics (QM) is the foundation for science and engineering disciplines as diverse as physics, materials science, chemistry, and nanotechnology. However, educators face major challenges in teaching QM concepts to students given the abstract and non-experiential nature of QM. To address the above challenges we are creating and evaluating a virtual environment governed by the laws of quantum mechanics as a way to engage alternative ways of teaching and learning QM.

Abstract
Work in Progress: The theory of Quantum Mechanics (QM) provides a foundation for many fields of science and engineering; however, its abstract nature and technical difficulty make QM a challenging subject for students to approach and grasp. This is partly because complex mathematical concepts involved in QM are difficult to visualize for students and the existing visualization are minimal and limited. We propose that many of these concepts can be communicated and experienced through interactive visualizations and games, drawing on the strengths and affordances of digital media. A game environment can make QM concepts more accessible and understandable by immersing students in nano-sized worlds governed by unique QM rules. Furthermore, replayability of games allows students to experience the probabilistic nature of QM concepts. In this paper, we present a game and a series of interactive visualizations that we are developing to provide students with an experiential environment to learn quantum mechanics. We will discuss how these visualizations and games can enable students to experiment with QM concepts, compare QM with classical physics, and get accustomed to the often counterintuitive laws of QM.




Design Process


Introduction
Quantum mechanics is a foundational subject in many fields of science and engineering. However, quantum mechanics is difficult to teach because it is abstract and built on probabilistic concepts that appear counterintuitive to students. Introductory quantum mechanics courses and texts predominantly focus on the mathematical formulations of the subject and lay less emphasis on its conceptual understanding. As a result, students often struggle to develop robust mental models that are necessary for its understanding. Particle in a Box is a 2-D platformer game to visualize quantum mechanics concepts and supplement student learning of the subject.


Challenges
1. How can the design environment enable students to build on their past experiences and knowledge, while facilitating their ability to break free from it?
2. How can we design an integrated environment that is both scientic and immersive; serious and playful?
3. How can we design a game character that is relatable and gender-neutral, thus breaking free from the stereotypes of a male-dominated discipline?


1. Building on students' past experiences
One first main challenge was to provide a basis for comparison to demonstrate how concepts such as energy, position, and momentum differ across classical and quantum mechanics. The broad strategy of our game is that of comparison. More specifically, the game is divided into two worlds: the classical mechanics world (Fig. 3) and the quantum mechanics world (Fig. 4). Objects in the classical world behave in ways that are familiar to everyday experience, while objects in the quantum world behave unexpectedly.

classical world
Fig. 1 The classical world is depicted by an abstracted lab setting. The objects on the shelves in the background reference familiar macroscopic objects. The particle (ball) here behaves in a way familiar to everyday experience.

quantum world
Fig. 2 The quantum world is depicted in a darker tone to convey a sense of mystery. The background represents an atomic environment (a lattice structure) in which the nano-sized quantum systems normally exist. The particle (electron) here behaves in an unfamiliar way.


2. Integrated Environment
The second key challenge we faced was to design a visual environment that was both scientific and immersive; serious and playful. Our response to this challenge was to create an integrated environment that combined the scientific representations of quantum mechanics concepts with the game environment.

wave function

energy level
Fig. 4 Concept of the energy levels - A change in the energy level of the electron adds more peaks and nodes to the wavefunction (blue curve). This change is represented in two sequential static figures.


2.1 Iterative Design Process
The design of the integrated environment followed an iterative process. Many of the game elements in both worlds changed as a result of frequent user testing and discussion. For example, the energy sources in the old iteration of the classical world were “weights.” However, they were not read as weights and appeared to the students as “suitcases.” We then used a different visual metaphor connected to the idea of “lifting weights” in the next iteration. This still did not connect to the idea of the ball absorbing energy. We nally changed the weights to bolts to better represent the idea of an energy source (Fig. 5). This kind of iterative process was adopted for all other design changes to the environment.

2.2 Tutorials
Given the abstract nature of QM concepts and the educational aims of the game, it was important for the game to include simple tutorials that helped players learn how to play the game. In earlier versions, the tutorials were 3-4 pages of text presented before the beginning of each level with each page accompanying an image to explain a key concept (Fig. 6). However, in our evaluations, most students told us that this feature made the game feel more like an interactive textbook than a game because the tutorials hampered the game experience. Our latest iteration presents tutorials as small challenges before the start of each level in the game environment itself (Fig. 7). The tutorial level builds up and explains the environment step-by-step. The player is guided to perform a necessary game action (such as bringing an energy bolt to the ball) to facilitate introduction and use of a concept. Upon completion of the tutorial, the player is left to complete the remaining level, where he must apply the concepts learned, in order to cross the level. Through this strategy, we give players enough support at the beginning to start playing the game while leaving room for explorative learning through trial and error as in other game environments.

The player can easily go back and forth between the tutorials using the “back” and “next” buttons. The elements that are explained in the tutorials are highlighted in the game using arrows, to help the player focus on speci c parts of the interface.


3. Neutral yet Relatable Character
The third key challenge we faced in the game design was to design a relatable and gender-neutral character, breaking free from the stereotypes of a male-dominated discipline. There is a large gender disparity both in science and gaming. Research suggests that students might reject a game if it does not respect their gender identities.

New design
Going further, we want to test the effectiveness of this method for concepts of higher complexity. We are also considering expanding the game to support multiplayer gameplay. This will allow us the opportunity to explore video games as a collaborative learning space.
