O estudo envolveu conhecimentos em educacao e Engenharia de Usabilidade, que orientaram e forneceram parâmetros metodologicos visando a melhoria de processos de avaliacao de software educacional infantil. A metodologia e as heuristicas foram validadas por meio de testes com programas didaticos infantis prontos e em desenvolvimento, em um processo evolutivo, ajustando-as a cada teste. Elas podem ser utilizadas em avaliacoes formativas, colaborando para que o desenvolvedor descubra defeitos e modificacoes necessarias no programa, ou em avaliacoes somativas, com ferramenta de apoio a escolas, pais ou interessados na escolha do software educacional infantil a ser utilizado pelas criancas.

In a software development project, testing is essential to assure product quality. However, it is a time consuming activity, and its work must be estimated for successful project execution. In our research, we concentrate our efforts on comparing some known methods of test effort estimation. So, this paper aims to analyze three different test effort estimation methods and compare them with the effort spent on real projects. Firstly we compare two widely used effort estimation methods: Test Point Analysis (TPA) and Use Case Points (UCP). Thereafter, we create an artificial neural network (ANN) based on the TPA, trained to estimate the testing work in software development projects, and compare it with pure TPA, to check which of them results in better estimates. Analyzing the experiment results, we concluded that the neural networks gave the best results, followed by TPA and then UCP.

In this context, cultural aspects can influence and interfere in a successful implementation of a software process improvement program. This paper explores cultural issues, discussing in a detailed way one de-motivator factor to implement successfully a software process improvement action. The analysis was carried out in a software development organization and provided some insights into how this organization would overcome it. We backed our studies conducting a process simulation. Our findings suggest that other than finance, technology and other issues, the cultural aspects should be among the first concerns to be taken into account when implementing a Software Process Improvement program. Our main contribution is to give evidences that a small change in the behavior of the software development team members can improve the quality of the product and reduce development rework.

Simulations are accepted as a complementary mode for the traditional teaching methods by stimulating and motivating learning through providing a realistic environment for the students to practice. They can engage students in a more enjoyable simulated experience of the real world. This article explores

It measures software functionality from the user's perspective, usually based on a requirements description. In many software processes, these requirements are represented by UML models. Although there have been attempts to automate the measurement process, FPA counting requires a considerable amount of interpretation which, to be reliable, should be made by experts. On the other hand, fully manual counting methods usually fail to keep synchronized with the requirements model, since requirements frequently change during the development cycle. This paper describes an approach for counting FPA and a compliant tool. This approach makes use of UML requirement models. The tool, called ReMoFP (Requirement Model Function Point counter), leaves all the counting decisions to the analyst, but supports him by ensuring consistency with the requirements represented in the models. The ReMoFP was developed by...

In the Software Engineering field, simulation games are commonly used for enhancing the learning and understanding of complex themes such as software processes. This complexity is represented by intrinsic software development characteristics such as multiple feedback loops and cause-effect delays. One fundamental aspect for the development of a simulation game is the definition of its simulation model. A simulation model contains some dynamic features and phenomena of the system it represents. It typically involves a set of assumptions concerning the system operation and it is used to translate the underlying system model, with given inputs, producing its behavior pattern. In this work, we describe an approach to create an educational simulation model derived from academic and industrial experiences. We focus on the systematic activities executed during its development. The created model was applied in a Software Process Improvement simulation game, named SPIAL (Software Process Improvement Animated Learning Environment). A set of important issues were identified. Our work can help developers during the creation of simulation games for educational purposes.

Specifically, a Requirements Engineering (RE) process was tailored and improved to comply with the organization business goals. We discuss challenges faced and proposed solutions, focusing on automation and integration support for RE activities. We use stereotypes to enhance UML diagram clarity, to store additional element properties, and to develop automated RE process support. Stereotypes are one of the core extension mechanisms of the Unified Modeling Language (UML). The benefits founds in their use in a software development organization support the claims that stereotypes play a significant role in model comprehension, reduce errors and increase productivity during the software development cycle.

One important research issue is providing support for simulation games development, making the results of their adoption successful in Software Engineering courses. In this work, we identify a set of requirements focusing on some of the Constructivist learning theories. These requirements were used to evaluate Software Engineering simulation games. Based on these requirements, we created FASENG, a framework for development of Software Engineering simulation games. FASENG has three main components: simulation model, simulator, and simulation engine. Since there is a clear structural and conceptual separation among them, they can be reused in other development environments. In order to check the framework flexibility, we developed two distinct Software Engineering simulation games. The two main results of this research are a better understanding of Software Engineering simulation games requirements and the development of FASENG.

However, these courses lack a practical opportunity for students to experience them more effectively. Even with the team-based project approach it is not possible to train students in all the real situations of a software development organization, due to the very nature of software applications and the large variety of organizational cultures. Simulation games are an appropriate complementary approach to the traditional educational techniques. Students' preparation can be improved by allowing them to practice, through a simulator, activities that are infeasible to practice during a Software Engineering course, due to restrictions of time and resources. Unfortunately, the creation of a simulation game is not a straightforward activity; it involves many different skills and addresses different viewpoints. In this work, we discuss the issues and challenges associated with the creation process of a Software Engineering simulation game. We adopted an incremental and iterative approach, where each step involves different knowledge, allowing us to point out a set of important aspects that should be taken into account during the development. These aspects can guide new developers and instructors in the design and selection of educational simulation games.
