Item A TASK FLOW DESIGN TOOL FOR SERIOUS GAMES: AN EXTENDED VERSION OF UML-AD (UML-ADE)(2014-10-06) TOPALOĞLU, Eda; ÇAĞILTAY, NergizBy improving technology, serious game is widely used by several areas such as defense, science, exploration, health care, emergency management, military management, city planning, engineering, religion and politics. However, development and design of these serious games is more important than playing them. Therefore, in order to create successful serious games, involving domain experts and end-users into the development process is important and necessary. During the development process, communication among those people is a very critical factor to better design and development of the game features according to the expected outcomes. In this study, UML Activity Diagram (UML-AD) is analyzed to represent the scenario flow of a serious game and document the serious game design. Additionally, for the design of serious game, an extension of UML-AD, named as UML-Activity Diagram Extended (UML-ADE), is proposed. The main purpose of the UML-ADE model is to improve the level of understandability of the UML-ADE with both the domain-experts, technicians and end-users. Therefore, the understandability level of the proposed UML-ADE model by technicians is investigated, evaluated experimentally. Results of this study show that the understandability level of proposed UML-ADE model is significantly higher than that of UML-AD.Item UNDERSTANDING THE EFFECT OF SERIOUS GAMES ON SURGICAL EDUCATION WITH RESPECT TO SIMULATION ENVIRONMENTS(2015-01-30) GÜNEY, Sinem; ÇAĞILTAY, NergizSerious games and simulations today are providing several benefits for areas such as education, training, health, military as well as commercial systems. However, the borderline between these environments is not very clear in literature. This information is important for designing more appropriate instructional systems according to the variations on learners’ behaviours and their expectations. Our main assumption is that, depending on their experience levels, knowledge levels and individual differences, learners may behave differently on simulation or game based educational systems. Then, as a part of neurosurgery Education Project (ECE), a simulation environment was developed in two versions by applying a gamification approach and simulation. Afterwards, an experimental study was conducted to better understand the effect of gamification on beginners of such an education program. The results of this study indicate that the success rates of the participants for performing assigned tasks in both versions of the application did not change significantly. On the other hand, the gamification group has spent significantly more time for performing the assigned tasks by rarely referring to the navigation feedback. This consequence is evidence showing that the participants’ behaviours have differed in simulation and game-based environments. The results of this study is expected to provide innovative perspectives to the instructional system designers for improving possible benefits of simulations and games in different fields and user groups.
