FormalZ is a browser-based education game that teachers can use to break the typical monotony in a class on formal method by allowing students to have some fun playing the game, while also learning the basic of writing formal specifications. Unlike existing software engineering themed education games, FormalZ takes a deeper gamification approach, where ’playing’ is given a more central role. After all, what makes games so engaging is not merely the awarded scores and badges, but primarily the experience of playing them. The ultimate research question that intrigues us is whether such an approach will actually make a difference towards the game’s ultimate learning goal. This is still on-going work. Currently, we have a fully functional implementation of FormalZ, but polishing the user interface is still future work.

Abstract: Computer science students often find doing exercises in writing formal structures to be boring, and yet this is a useful skill to have, both academically and practically. Providing some of the exercises as a game may help in making the learning process more engaging, while in addition is also useful as an automated trainer. However, developing an education game is quite an endeavour. Additionally, after the development we also have to maintain the system. This paper presents a template that can be instantiated for a given target formal system to give a minimalistic set of game concepts to turn formalization exercises in this formal system into game based exercises. The template is derived from a game called FormalZ, as we observe that its core game concepts are actually general and can be reapplied to other use cases. Along with the template this paper also proposes a light weight architecture that would allow game based exercises to be developed maintained with less effort.

Abstract: Writing formal specifications is a useful skill for students to develop and to grow a positive mindset towards it. Unfortunately this is hampered by the stereotyping of formal method as dry and boring. In this short paper we discuss our experience in using of a computer game called FormalZ as an attempt to introduce some fun in teaching the skill. Two setups are discussed: as an embedded part of a course, and as a loose tutorial, afterwhich we will conclude with the lessons learned.

Abstract: There are many benefits in providing formal specifications for our software. However, teaching students to do this is not always easy as courses on formal methods are often experienced as dry by students. This paper presents a game called FormalZ that teachers can use to introduce some variation in their class. Students can have some fun in playing the game and, while doing so, also learn the basics of writing formal specifications in the form of pre- and post-conditions. Unlike existing software engineering themed education games such as Pex and Code Defenders, FormalZ takes the deep gamification approach where playing gets a more central role in order to generate more engagement. This short paper presents our work in progress: the first implementation of FormalZ along with the result of a preliminary users’ evaluation. This implementation is functionally complete and tested, but the polishing of its user interface is still future work.

Prasetya, Gordon Fraser, Ivan Martinez-Ortiz, Ivan Perez-Colado, Rui Prada, José Rocha, António Rito Silva. Presented at the International Conference on Product-Focused Software Process Improvement (PROFES) 2019.
Abstract: Software Engineering courses play an important role for preparing students with the right knowledge and attitude for software development in practice. The implication is far reaching, as the quality of the software that we use ultimately depends on the quality of the people that make them. Educating Software Engineering, however, is quite challenging, as the subject is not considered as most exciting by students, while teachers often have to deal with exploding number of students. The EU project IMPRESS seeks to explore the use of gamification in educating software engineering at the university level to improve students’ engagement and hence their appreciation for the taught subjects. This paper presents the project, its objectives, and its current progress.
