Serious games are a growing field in academic research and they are considered an effective tool for education. Game-based learning invokes motivation and engagement in students resulting in effective instructional outcomes. An essential aspect of a serious game is the method of support for presenting the teaching material and providing feedback. A support design that evaluates students' progress and adapts accordingly, has the potential of producing better learning results. This paper presents an adaptive model based on fuzzy logic that adjusts the support acquisition according to student knowledge level. A serious game for teaching the concepts of sequence and iteration in programming to novice students was built to assess the model. It employs working examples as a support method since previous research indicated that it produced less cognitive load during problem-solving. An empirical study with 102 students has been conducted to evaluate the learning efficiency of the model. The analysis indicates positive results and a potential solution for balancing the amount of assistance in serious games.

There has been an active movement towards fun learning, using games in education. This article introduces the text-based serious game "Rise of the Java Emperor" that aims to support students in learning basic object-oriented programming concepts using Java. Information concerning the analysis, the design and the pilot evaluation of the game is presented. Thirty three undergraduate and postgraduate students of an Applied Informatics Department voluntarily played and answered a questionnaire based on the MEEGA+ model, in order to investigate the perceived player experience and short-term learning as well as the acceptance of a text-based programming game by students. The results of the evaluation show that text based games can be both fun and instructional for the field of computer programming. An important issue that requires further research is how this or other programming games can be successfully combined with traditional teaching methods for enhancing the learning of programming.

Serious games (SGs) about Chemistry have the potential to cope with challenges, such as students' low performance and lack of motivation for the subject. However, the majority of existing SGs for Chemistry have the form of educational applications infused with some elements of entertaining games. The aim of the study presented was to design and evaluate a new SG with rich game mechanics for Chemistry. The game is called Elementium and revolves around basic topics of Chemistry, such as chemical elements and compound terminology, creation and everyday usage of such elements. The main goal of the game is to familiarize junior high school students with the aforementioned subjects. The design of Elementium was carried out implementing the dimensions described in the Four-Dimensional framework, as proposed by de Freitas and Jarvis in 2006. After the development process, Elementium was evaluated by people in the field of education that are currently teaching or have taught Chemistry in the past. The participants play-tested the game at leisure in their homes and evaluated it based on the key criteria for SGs design proposed by Sanchez in 2011, as well as other quality indicators established in the literature. Elementium was positively evaluated by Chemistry teachers in terms of its acceptance, usability, didactic utility, and game environment. The positive results concluded from this evaluation show that Elementium is fulfilling its main purpose and can be used as a supplementary tool in the teaching process. However, its true didactical effectiveness has to be confirmed through a study with high school students.

At 21st century Computational Thinking (CT) is considered a fundamental skill that anyone should possess and develop from a young age. Serious games and more specifically educational games (EGs) are a promising means of introducing algorithmic thinking and programming concepts and engaging students through the process of learning. In this article, a new EG called BlocklyScript is presented. BlocklyScript aims to help students develop their CT by learning basic programming concepts, designing algorithms and correcting mistakes. During the designing phase different EGs were taken under consideration and an EG design framework was followed in order to provide a better user experience. The game was evaluated by 10 experienced computer science educators of primary and secondary schools. The positive results of this pilot evaluation show that BlocklyScript is expected to help students understand the basic concepts of CT. However, the game should be evaluated by more teachers and students in order to provide future researchers with safe results.

Serious games are considered an effective method to engage students in programming education and have been increasingly used in classrooms. An important part of the learning process with serious games involves the presentation of the new concepts and the provided support to encounter student difficulties. Although the most common approach is the use of instructional text, it comes with some drawbacks. This paper proposes an alternative method for user support in serious games about programming which mitigates current problems and provides improved learning efficiency. An experiment was conducted (N = 291) to test textual instructions learning efficiency compared to in-game worked examples. Two randomly assigned groups used different types of support in a block-based game, developed for the study. Our implementation provided support through a non-player character who executed worked examples inside the game world. The analysis showed a significant statistical difference in score performance between the two supports on both novice and experienced students. The results point to increased learning efficiency by students, when in-game worked examples and problem-solving are combined. We further argue that the Cognitive load theory can provide adequate justification for the outcomes.

Serious games, or else educational games, for programming are considered to have a positive impact on learning programming. Specifically, serious games are considered to motivate students and engage them in playing and learning programming. However, more research is required in order to study their effects in learning programming, as well as their added value in comparison with typical teaching approaches. In this study the effects of teaching programming to lower secondary school students with the serious game CodeCombat and the typical teaching approach are compared. Specifically, fifty-nine students formed an experimental group that was taught programming with CodeCombat and a control group that was taught programming through lecturing and problem solving in Python with a typical programming environment. The study aimed to investigate whether a game like CodeCombat that is based on a text-based real programming language: improves students' performance in basic programming concepts; brings better learning outcomes in comparison with typical teaching methods; engages students' interest. Data was collected through a pre and post test, as well as a survey prior the intervention and another one based on the Technology Acceptance Model at the end. It was concluded that the experimental group performed better than the control group, but this difference was not found to be statistically significant. CodeCombat was evaluated positively in terms of its perceived ease of use and usefulness, as well as the attitude towards its use. The results were neutral in terms of students' behavioral intention to use CodeCombat, but were positive in using serious games for programming in general.

Theoretical subjects, such as history, usually do not attract the interest of students and as a result educational games and serious games that use augmented reality (AR) are increasingly used as a means of supporting education. It is believed that these games can make the lesson more engaging and contribute to improving student performance. However, relevant research is limited. The present research presents the AR-enhanced serious game "Exploring Ancient Greece" that aims at supporting 10- to 14-year-old students in learning the history of Ancient Greece. It consists of three levels that include: a presentation of archaeological sites with AR that gives students the chance to explore places of historical interest; a trivia game that includes an AR presentation of a monument or piece of art somewhere in the physical surroundings of the students; and an escape room where the player is trapped in an archaeological site and tries to solve riddles to find the exit. To evaluate the game, an empirical study was conducted involving students between the ages of 10 and 14 who answered knowledge questions before and after playing the game, completed a questionnaire including questions based on the System Usability Scale (SUS), as well as questions for evaluating their experience, and answered oral questions. Based on the results of this study, students improved their knowledge of history, evaluated the game positively and stated that they prefer the use of serious games and AR in education.

Serious games or educational games have attracted the interest of instructors and researchers for several years. In the field of education, serious games are being used for motivating students, attracting their interest in cognitively demanding fields and making the teaching and learning process more fun. Moreover, learning through implementing games has been proposed as an effective alternative to the traditional instructor-centered approach to teaching programming. Towards this direction the study presented in this article aims to investigate whether it is feasible to learn programming concepts, as well as game programming concepts, through implementing a game in Python. More specifically, the study presented has the following goals: firstly, to review and comparatively analyze existing game engines and libraries that can be used by novice programmers for implementing simple games in Python; secondly, to investigate whether it is feasible to implement a simple but yet meaningful game that can be used as a prototype for learning programming concepts and game programming concepts in Python. In order to reach the second goal a serious game was implemented as a case study, using the free and open source Python library of pygame that based on the aforementioned comparative analysis is appropriate for novices. The PyDiophantus Maze game that was implemented can be used for teaching and learning game programming in Python, but also for learning mathematics. The article concludes with proposals for utilizing the game in mathematics and (game) programming education, as well as plans for further research.

Designing serious games (SGs) for people with intellectual disability (ID) and autism spectrum disorder (ASD), requires proper planning and decision making. In this article, a proposal of a serious games design framework (GDF) that aims to assist designers and special education teachers and professionals develop successful SGs for people with ID and people with ASD, is presented. In order to create this GDF, an extraction of SGs design guidelines from existing SGs for people with ID and ASD and a comparative analysis with common GDF that are used for designing SGs in general was conducted. The proposed design guidelines and the conclusions of the comparative analysis of existing general purpose GDFs were used as a tool to design a computer-based SG that aims to improve independent living skills of people with ID and people with ASD. Based on this previous work the proposed GDF that is analyzed in this article was devised. This work aims to fill the gap in the field of designing SGs for people with ID and ASD by providing a specialized and informed GDF.

Since pair programming appeared in the literature as an effective method of teaching computer programming, many systems were developed to cover the application of pair programming over distance. Today's systems serve personal, professional and educational purposes allowing distributed teams to work together on the same programming project. The current research focuses in distributed pair programming systems which are suitable for supporting students in learning computer programming. Systematic review of publicly available systems revealed that there is an absence of effective collaboration support for the students. The main drawbacks of pair programming, such as uneven workload distribution and infrequent role switches, cannot be addressed with available systems. While building an enhanced version of a distributed pair programming system, successful instructional strategies in similar collaborative learning systems were explored, in order to improve students' interactions when applying pair programming over distance. As a result, the new system allows students to practice distributed pair programming in the form of collaboration scripts. This paper presents the features and the underlying concepts of the system, and the results of its first evaluation. The study showed that distributed pair programming attracted positive feedback from students, and that scripted collaboration affected students' engagement in programming, and resulted in an evenly distribution of learning objectives among pairs.

Computer science is continuously evolving during the past decades. This has also brought forth new knowledge that should be incorporated and new learning strategies must be adopted for the successful teaching of all sub-domains. For example, computer programming is a vital knowledge area within computer science with constantly changing curriculum and its teaching remains a difficult endeavour. On the other hand, students start from a very early age to interact with computers through games and other entertaining multimedia software. Therefore, they seem to be keen on environments with impressive special effects and graphical interfaces where they interact with the environment's elements. In response, teachers are trying to connect computer programming learning with computer operations that students are familiar with, which does not include textual editors for programming lines of code with no other interaction. Educational games used in computer programming courses are considered to benefit learning, because they motivate students towards actively participating and interacting with the game's activities. Thus, we have developed an educational multiplayer game that aims to further enhance computer programming education by addressing occurring problems. This process, however, requires proper planning during the design of educational games, and thus the availability of adequate guidelines that include all characteristics that should be incorporated in such games. This paper aims to introduce and elaborate on a holistic framework that has been constructed as a guide towards the development of this game. To this end, we study existing frameworks that have been proposed for the design of educational games and document features currently supported by educational games that teach computer programming. We conclusively propose the framework we have constructed for the design of our game. This framework can be used for the design of other computer programming-specific educational games and extended for other educational domains.

Games for learning are currently used in several disciplines for motivating students and enhancing their learning experience. This new approach of technology-enhanced learning has attracted researchers' and instructors' attention in the area of programming that is one of the most cognitively demanding fields in Computer Science. Several educational, or else serious, games for learning programming have been developed and the first results of their evaluation as a means of learning are quite positive. In this paper, we propose using arcade games as a means for learning programming. Based on this approach students first play a simple game, such as Snake or Tetris, study its code and then extend it. In a pilot study carried out in the context of an undergraduate programming course, students studied the source code of the well-known game Snake and extended it with new functionalities. The analysis of students' replies in a questionnaire showed that using arcade games as a means of learning programming concepts enhances students' motivation for learning programming, supports them in comprehending complex concepts and engages them in carrying out programming activities.

Pair Programming has been shown to increase productivity and code quality not only in professional software development but also in the context of programming education. The provision of broadband Internet access gave rise to Distributed Pair Programming (DPP) enabling two programmers to collaborate remotely. To gain insight into the benefits of DPP, we performed an empirical study on an object-oriented programming course where 62 students carried out assignments through a DPP platform. The goal of the study is to investigate, in the context of DPP, whether prior programming skills (assessed at the level of student, his or her partner and pair) and pair compatibility are related to student performance. To further examine the effect of DPP on learning outcomes, we have studied whether a pair's performance on DPP assignments is related to the students' grade. The findings indicate that the student's actual skill and the pair's actual skill affect his or her performance in an object-oriented programming course. The results also suggested that there is no association between pair compatibility and his or her own performance. Finally, pair performance on DPP assignments is related to the individual student performance in the final exams. Such evidence can be used to guide instructors when planning DPP assignments and especially when forming student pairs.

This study examines the available literature on the effects of serious games on people with intellectual disabilities or autism spectrum disorder. The studies were categorized based on the limitations in skills that these people address. Fifty-four studies were selected, from different data sources. These studies address limitations in intellectual functioning and adaptive behaviour. The results showed that the majority of studies on the effects of serious games for people with intellectual disabilities or autism spectrum disorder had a positive impact. Also, most studies for people with autism aim to improve social and communicational skills, whereas conceptual and cognitive skills were mainly observed in studies for people with intellectual disabilities. Although this study covers serious games in all platforms or delivery systems, the overwhelming majority of the presented studies include computer serious games. Computer-assisted learning through serious games is considered quite promising for people with intellectual disabilities or autism spectrum disorder.

Educational games are increasingly used in informal and formal educational settings for promoting active learning and gaining students' interest in cognitively demanding subjects, such as programming. However, empirical studies that investigate the true impact of educational games on teaching and learning programming, especially to small aged students, are limited. This article presents the results of a pilot study that utilized the educational game "Run Marco" for teaching basic programming concepts to primary school students. Students' performance was studied through specially designed worksheets, while their acceptance of the intervention was evaluated through a questionnaire that was based on the principles of the Technology Acceptance Model (TAM). The results of the pilot study showed that the educational game supported students in comprehending basic programming concepts, while the results regarding the acceptance of its usage in the learning process were quite positive. However, the game did not succeed in raising students' interest as expected and further research is necessary in order to study the reasons for this fact and make informed choices on designing and utilizing such games.

The choice of the first programming language (FPL) has been a controversial issue for several decades. Nearly everyone agrees that the FPL is important and affects students' subsequent education on programming. The study presented in this article investigates the suitability of various C-like and Pascal-like programming languages as a FPL. Students from three Universities express their perceptions on the FPL through a specially designed questionnaire. The students had been introduced to programming using different FPLs and having experience on more than one language and formulated two distinct groups: a group introduced to programming with a C-like and another with a Pascal-like language. The statistical analysis of the data collected showed that the choice of the FPL does not have a deep impact on difficulties that novices may experience when learning the basics of programming. However, this result was recorded in the context of three distinct programming courses that were positively evaluated by students in relation to their content, organization and quality. Consequently, this study indicates that the overall quality of the course and the instructors have a great impact on a smooth introduction to programming no matter what the FPL is.

Technology enhanced learning (TEL) is increasingly influencing university education, mainly in overcoming disadvantages of direct instruction teaching approaches, and encouraging creativity, problem solving and critical thinking in student-centered, interactive learning environments. In this paper, experiences from object-oriented programming (OOP) courses that are taught in three institutions from three different European countries are presented and compared. The courses are based on Java and are delivered in the second year of studies, after students have attended an introductory programming course. The emphasis is given on TEL approaches and accompanying tools and services, focusing mainly on Learning Management Systems (LMS). Our students completed an appropriate questionnaire to evaluate the importance and utilization of TEL services that are used or planned to be used at the programming courses. The results of statistical analysis of collected data show that students from all three institutional groups consider organizational services provided by TEL tools as much or very much important in their education, while communicational services are rarely used. Using non-parametric statistical tests we studied the similarities and differences in perceived importance of TEL services among students from different institutional groups.

Teaching and learning programming, and especially Object-Oriented Programming (OOP), is a complicated and challenging task. Students have to comprehend various OOP concepts and utilize them for designing object-oriented programs. Various types of educational programming environments, such as microworlds and educational games, have been devised for supporting novices mainly in comprehending OOP concepts. However, such environments do not usually support students in the conceptual design of object-oriented programs of a considerable length and complexity. In this paper, we focus on a systematic mapping study (SMS) of educational programming environments for enhancing the conceptual design in OOP, which relies on modularity, abstraction and encapsulation. The research questions investigate the intended learning outcomes, the empirical evidence on the effectiveness, and the teaching/learning technologies used by educational programming environments for enhancing the conceptual design in OOP. The findings can support instructors in selecting appropriate tools for their courses and researchers in the field of educational programming environments for OOP. [ABSTRACT FROM AUTHOR]

Teaching and learning programming constitutes a challenge. Although several teaching approaches and programming tools have been proposed, it seems that they have limited impact on classroom practice. This article investigates students' perceptions on five educational programming environments that are widely used and the features that any introductory programming environment should have. The environments investigated are: BlueJ; objectKarel; Scratch; Alice; and MIT App inventor. These environments were studied and used by experienced undergraduate students of Informatics in the context of a fourth year course. The main features of the environments and the way of presenting them to students, as well as the assignments in the context of the course are presented, in order to help the reader realize what experience was gained by the students that evaluated the environments. Based on a questionnaire filled in by students interesting conclusions were drawn. Students identified the main features of the environments and evaluated them positively, although problems were identified. An introductory programming environment should engage students through the development of programs connected to their interests, such as games and mobile apps. Moreover, an ideal introductory programming environment should provide a simple and user-friendly Graphical User Interface (GUI) that supports visualization of objects and classes, includes a puzzle-like editor for program development, reports simple and understandable error messages in natural language, and finally the ability to execute the program in a step by step manner. Although no single environment fulfils all these features, it seems that the most successful environment is Scratch.

Computer programming has for decades posed several difficulties for students of all educational levels. A number of teaching approaches have been proposed over the years but none seems to fulfil the needs of students nowadays. Students use computers mainly for playing games and the Internet and as quite a few researchers state this aspect of computers should be taken into account in the way we educate them. Towards this direction, this paper aims to examine the effects of using an educational Massive Multiplayer Online Role Playing Game (MMORPG) on teaching and learning computer programming. The educational features of an MMORPG called CMX are presented along with a design framework that was devised taking into account previous work in designing educational games. The effects of CMX on teaching and learning computer programming are assessed through a study with first-year undergraduate students. Seventy six students used CMX over a period of five weeks for learning various procedural programming concepts. Students evaluated various aspects ofCMX by filling in a questionnaire that was based on an evaluation framework, which was devised in accordance with the design framework of CMX. Moreover, the results of a midterm exam that took place prior to using CMX and students' accomplishments in the context of CMX were recorded and analyzed. The results show that the majority of the students was entertained by playing the game while learning, and felt motivated to continue based on the game's scenario due to the variety of activities included. In regards to the students' performance, a pre-test and a post-test were carried out in the experimental group, i.e., the participants of this study, and the control group, i.e., students of the course that continued to get taught the same concepts and performed the same assignments as the experimental group, but traditionally. The pre-test and post-test analysis of the performance results for both groups showed that the majority of the students in the experimental group increased their performance in computer programming. Furthermore, students stated they had a positive attitude in regards to re-using CMX in the future in order to learn additional programming concepts. The positive results of this study pave the way for CMX being used in the classroom and expanding the game's functionalities that will further increase students' performance and support teachers in delivering the required knowledge. Moreover, the work reported in this paper offers game designers and teachers methodological and empirical results for game-based learning in such a difficult domain as is computer programming. What is more, the design and evaluation frameworks presented are general enough that they can be easily adjusted and/or extended for designing and assessing educational games in other domains as well.
