In this thesis, an improved framework is proposed for categorizing existing gamified systems. Related works and real world examples of gamification are discussed and some areas where insufficient research exists. In order to address the identified research problems, an experimental gamified system was designed and implemented for sharing articles related to different aspects of life. The participants of the study were recruited among the users of an existing Iranian lifestyle site for female users. Therefore, the gender of the users was considered in the design. A wide range of gamification elements were implemented in the system to test the effectiveness of specific design features and gamification elements’ parameters in increasing user motivation, for example, the contingency of rewards and the use of sound and animation in badges. A detailed questionnaire was used to answer the research questions. The results suggest specific combinations of gamification elements and their parameters that can be successfully applied by designers of social sites for similar audience.

This study intented to investigate the effects of activities based on role-play on ninth grade students&rsquo / achievement and attitudes at simple electric circuits. In this study, Physics Achievement Test was developed to evaluate students&rsquo / achievement on simple electric circuits and role-play activities about simple electric circuits were prepared. In addition, Physics Attitude Scale was administered to explore students&rsquo / attitude towards physics. The present study was conducted at one of the high schools in Acipayam during 2003-2004 Spring Semester with a total number of 104 (51 female and 53 male) 9th students from four classes of two physics teachers. One class of each physics teacher was assigned as experimental and instructed by role-play activities on the other hand the other classes of each physics teacher was as control group and instructed by traditional method. The teachers were trained for how to implement role-play activities in the class before the study began. Physics Attitude Scale and Physics Achievement Tests were applied twice as a pre-test and after a three-week treatment period as a post-test to both groups to assess and compare the effectiveness of two different types of teaching / role-play versus traditional teaching method. Data were collected utilizing Physics Achievement Test and Physics Attitude Scale. Data of this study were analyzed utilizing descriptive and inferential statistics. The scores of the post-tests were analyzed by statistical techniques of Multivariate Analyses of Covariance (MANCOVA). Experimental group compared to control group tended to favor a significant difference in the achievement. However the statistical analysis failed to show any significant differences between the experimental and control groups&rsquo / attitude towards physics at simple electric circuits.

Strategies in games have since long been of interestto humans, mainly to beat our friends in games such as Chessor Monopoly, but also to model real world scenarios. Thesestrategies are often difficult to find, even more so if the playerslack important information about the current state of the game.Pursuit-Evasion games are a type of games that can be usedto model police chasing criminals, autonomous car collisionavoidance systems and many other scenarios. It is therefore ofinterest to find effective strategies in these scenarios.This bachelor thesis project examined Pursuit-Evasion gamesof imperfect information on grids where a number of pursuerswork together to capture a number of evaders whose locationsare unknown. A set of knowledge-based strategies, one of theminspired by the Knowledge Based Subset Construction, wereexplored and analyzed. The strategies were compared againsteach other and against both an optimal strategy where thepursuers always were aware of the evaders whereabouts anda reference strategy where the pursuers moved randomly.The constructed strategies proved to be efficient in comparisonto the reference and in cases even close to the optimal strategyin efficiency. / Strategier i spel har sedan länge varit avintresse för oss människor, framförallt för att vinna mot vårakompisar i spel som Schack eller Monopol, men också för attmodellera verkliga scenarion. Dessa strategier är ofta svåra attlista ut, och ännu svårare då spelarna saknar viktig informationom spelets nuvarande läge. Pursuit-Evasion är en klass av spelsom kan användas för att modellera polisjakter eller kollisionsundvikandesystem i autonoma bilar för att nämna några. Detligger därför i vårt intresse att finna effektiva strategier i dessascenarion.Detta kandidatsexamensarbete studerade Pursuit-Evasion spelav imperfekt information på rutnät där ett antal så kallade pursuerssamarbetade för att fånga ett antal så kallade evaders varspostioner var okända. En kunskaps-representation utformadesoch en mängd kunskaps-baserade strategier, en inspirerad avmetoden Knowledge Based Subset Construction, utforskades ochtestades. De olika strategierna jämfördes mot varandra och motbåde en optimal strategi då pursuers hade all kunskap om varalla evaders befann sig och en referensstrategi då pursuers rördesig slumpmässigt.De utformade strategierna visade sig vara effektiva i jämförelsemed referensen och i vissa fall till och med nära den optimalastrategin i effektivitet. / Kandidatexjobb i elektroteknik 2021, KTH, Stockholm
