Abstract in Portuguese
Teste de software é uma atividade do processo de desenvolvimento de software que busca revelar os defeitos presentes no software. Apesar dos constantes avanços e surgimento de diferentes modelos pedagógicos, este assunto continua sendo ensinado com o modelo tradicional de ensino. A comunidade de educação em computação vem investigando a aplicação de diferentes modelos pedagógicos e, nessa perspectiva, emerge o modelo pedagógico flipped classroom como uma interessante solução. Estudos mencionam sobre a necessidade de investigá-lo, buscando reconhecer seu potencial no ensino de um determinado conteúdo. Além disso, implementar o modelo exige uma intensificação de esforços para o professor, pois ele precisará planejar atividades e mecanismos de apoio ao ensino para cada um dos momentos previstos pelo modelo. Trabalhos relatam que os alunos durante o momento de estudo antes da aula podem ter dificuldade em entender aspectos teóricos sobre o conteúdo, pois esse pode ter conceitos que podem gerar dupla interpretação. Este trabalho de mestrado tem o propósito de contribuir com o ensino de teste de software, investigando o impacto do modelo flipped classroom no ensino de teste de software. O projeto também propõe uma abordagem de apoio ao planejamento e implantação desse modelo e analisa o uso de um agente conversacional como mecanismo de apoio ao flipped classroom. Estudos experimentais foram realizados visando entender o impacto do modelo no processo de aprendizado de teste de software. Na sequência, foram analisados conteúdos de teste de software ensinados em cursos de computação no Brasil, definidos objetivos de aprendizagem para esses conteúdos, selecionados mecanismos de apoio e atividades para contemplar os três momentos previstos pelo modelo e implementado um mecanismo para apoiar a implantação do modelo flipped classroom no ensino de teste. Por fim, um agente conversacional foi proposto e investigado no contexto de uma aula de teste de software em que o modelo flipped classroom foi utilizado. Os resultados deste trabalho indicam que o modelo flipped classroom permite que os alunos tenham melhores resultados no aprendizado, especialmente quando há realização de atividades práticas. Os alunos revelaram que preferem este modelo em detrimento ao tradicional. No entanto, o modelo produz uma carga de trabalho maior para o aluno. Por fim, o uso do agente conversacional como um mecanismo de apoio durante o momento antes da aula indica sua relevância para o flipped classroom.

Abstract in English
Software testing is an activity of the development process that aims to reveal the faults present in the software. Despite of constant progress and emergence of different pedagogical models, this subject is still taught with strategies based mainly on the traditional model. Although software testing is considered a relevant subject, some students are not very motivated to learn it. The computer education community has investigated the use of different teaching models and, from this perspective, the Flipped Classroom pedagogical model has emerged as an interesting solution. Several studies mention that is required to investigate this model in order to identify its potential in teaching a specific subject and/or teaching area. In addition, the implementation of this model demands an intensification of efforts from the teacher because he/she needs to plan activities and support mechanisms for all phases of this model: before the class, during the class, and after the class. Results from the literature indicate that students may present difficulties in understand the theory during the phase before the classbecause studying alone can lead to many doubts and misunderstandings. Therefore, this masters thesis investigates the impact of the Flipped Classroom model on teaching of testing techniques and criteria. Experimental studies were initially undertaken aiming to understand the models impact in the learning process of software testing. Following, we analyzed what subjects of software testing are taught in Computer courses in Brazil. Based on the results, we defined learning objectives for these subjects, selected support mechanisms and activities to contemplate the three phases of the Flipped Classroom model. An approach, named FlipClass-STT, to support the implementation of this model was defined and experimentally evaluated. Finally, the conversational agent TOB-STT was proposed and evaluated in context of a software testing class, in which the Flipped Classroom model was employed. The results of this work indicate that Flipped Classroom allows the students to have better learning outcomes, especially when performing practical activities. The students have revealed that they prefer this model against the traditional one. However, it is also observed that model produces a greater workload for the student. The use of TOB-STT how a support mechanism during the phase before the class indicate its relevance and impact for learning software testing.
