Informatics in Education

This research discusses the use of a gamified web platform for studying software modeling with Unified Modeling Language (UML). Although UML is constantly being improved and studied, many works show that there is difficulty in teaching and learning the subject, due to the complexity of its concepts and the students' cognitive difficulties with abstraction. There are challenges for instructors to find different pedagogical strategies to teach modeling. The platform proposed allowed students to complement their UML knowledge in an environment with game elements. From the results, it can be concluded that the platform obtained great acceptance and satisfaction of use. Most of the students participating in the research were satisfied with the usability of the platform, reporting a feeling of contribution of the tool to studying the content, in addition to pointing out the satisfaction of using gamification as a pedagogical strategy.

This study aims to explore how gamification elements influence the development of the Community of Inquiry (CoI) in an online project-based programming course conducted on Facebook. We formed student groups by using a quasi-experimental design from students studying in the computer science department. While both courses were project-based, the experimental group's project development process was enriched with gamification elements. We collected data from the CoI survey, transcript analysis of online discussions, and interviews with students. The results indicated that the use of gamification elements contributed significantly to students' social, cognitive, and teaching presence development. Besides, while a high level of CoI perception was created in both groups in the online project-based learning environment, the design and organization role of the instructor came to the fore in the gamified environment more.

The contents taught in the programming subjects have a great relevance in the formation of computing students. However, these subjects are characterized by high failure rates, as they require logical reasoning and mathematical knowledge. Thus, establishing knowledge through the subject of algorithms can help students to overcome these difficulties and absorb the contents and skills required. Thus, this work aims to present and discuss the results of a second experiment on the application of a teaching plan composed of several active methodologies (Virtual Learning Environments, Coding Dojo, Gamification, Problem-Based Learning, Flipped Classroom and Serious Games) in an algorithms subject. Based on this experiment, it was evaluated whether there were learning gains compared to the learning acquired with the traditional method. Finally, an analysis was performed using the two-tailed Student-t approach, used for independent samples, which presented statistically significant results.

This article presents an approach to using open-source tools and open-source projects to add realistic and practical examples to a course on software design in a professional master's program of software engineering. Students are encouraged to use object-oriented, open-source software projects available on the Internet, and to analyze their design attributes using open-source tools, to hopefully improve their designs using documented design patterns and other design strategies. The proposed approach provides a variety of realistic examples for study, which can vary from semester to semester, without the instructor having to prepare complicated realistic examples or to rely on over-simplified examples in textbooks. Because the course and the approach are relatively new, a quantifiable assessment of the pedagogical approach has not been presented. However, the argument is made that realistic examples provide for better learning, and evidence is provided to show the feasibility of the approach. The instructor's role is more of a mentor than a traditional teacher, as every open-source project is different from a design perspective.

This paper reports a multi-national, multi-institutional study to investigate Computer Science students' understanding of software design and software design criteria. Student participants were recruited from two groups: students early in their degree studies and students completing their Bachelor degrees. Computer Science educators were also recruited as a comparison group. The study, including over 300 participants from 21 institutions in 4 countries, aimed to understand characteristics of student-generated software designs, to investigate student recognition of requirement ambiguities, and to elicit students' valuation of key design criteria. The results indicate that with increases in education, students use fewer textual design notations and more graphical and standardized notations and that they become more aware of ambiguous problem specifications. Yet increased educational attainment has little effect on students' valuation of key design characteristics.
