The clinical significance of premature atrial contractions: How frequent should they become predictive of new-onset atrial fibrillation

[摘要] Based on the quantitative and qualitative analysis of collected data, this work examines energy engineering students’ perceptions towards web-based peer assessment, distinguishing their role as reviewers and as feedback receivers. It analyses the type of feedback in an attempt to evaluate students’ written communication skills and identifies which factors are related to students’ use and appreciation of feedback. Taking in account the conclusions of our previous case-study in the civil engineering course at University of Trás-os-Montes e Alto Douro (UTAD, Vila Real, Portugal) the results of this study allow us to deepen the reflexion on how to improve the design and implementation of future web-based peer assessment tasks in engineering courses.
