Q1. What have the authors contributed in "Gamification in software engineering education: a systematic mapping" ?
However, as SE educators the authors are particularly interested in understanding how gamification is pollinating their field and the extent to which the above claim is valid in their context. A systematic literature mapping has underscored the difficulty in fully corroborating the above claim because few empirical data are available so far. The authors have also discussed insightful issues regarding the implementation cost of gamification, patterns in the most often used gamification elements, and the SE processes and teaching activities addressed. Of the identified challenges, the authors should highlight the complexity of deciding which gamification approach to follow, the lack of information for choosing gamification elements and the need to control the impact of gamification.
