Abstract
Taking in account the conclusions of our previous case-study in the civil engineering course at UTAD (University of Tras-os-Montes e Alto Douro, Vila Real, Portugal) this work presents the results of a case study in an energy engineering undergraduate course. Based on the quantitative and qualitative analysis of collected data, it examines students.' attitudes towards web-based peer assessment, distinguishing their role as reviewers or as feedback receivers. It identifies which factors are related to students.' use and appreciation of feedback. Moreover, an analysis of the type of feedback is presented in an attempt to evaluate students.' written communication skills. The results of this study allow deepening the reflexion on how to improve the design and implementation of future web-based peer assessment tasks.

Abstract
This paper presents a modeling environment (ME) developed for a Domain Specific Language (PARADIGM) which aims to support the construction of models to be used in the context of Model Based GUI Testing (MBGT). It starts by briefly presenting PARADIGM which aims to increase the level of abstraction of the models and promote reuse in order to diminish the effort in building models for MBGT. Afterwards, it describes the architecture of the ME, how the constraints of the language are enforced within the ME to ensure the consistency of the models built, the test case configuration of the model elements, the test case generation algorithm and how the ME can be extended/adapted to include additional features.

Abstract
User Interface (UI) patterns are used extensively in the design of today's software. UI patterns embody commonly recurring solutions that solve common GUI design problems, such as "login," "file-open," and "search." Yet, testing of GUIs for functional correctness has largely ignored UI patterns. This paper formalizes the notion of a Pattern-Based Graphical User Interface (GUI) Testing method (PBGT) for systematizing and automating the GUI testing process. The space of all possible interactions with a GUI is typically very large. PBGT presents a new methodology to sample the input space using " UI Test Patterns," that embody commonly recurring solutions to test GUIs. Our empirical studies show that the PBGT methodology is effective in revealing faults in fielded GUIs.
