The main focus of this study was the inclusion of informal methods in the educational frameworks of architectural and urban design. The project used is based on the 3D representation of virtual models of new urban proposals in order to re-organize a local market in Tonalá, Mexico. Starting from a formal course, where the students had to develop solutions to(More)
This paper discusses the design of two educational proposals centered on Project-Based Learning (PBL) and the use of Information and Communication Technologies (ICT). Both courses are focused on the spatial representation of 3D models in architectural training. The object of study focuses on comparing the students' competence and motivation in two different(More)
Online quizzes are a powerful educational tool that allow learners to self-evaluate their knowledge. This paper analyzes the results of over 20,000 pre-university mock online quizzes in the technical drawing subject of the Spanish University Admission Test to assess the impact of (a) the presence of accompanying graphic illustrations and (b) the length of(More)
The current paper presents a qualitative assessment of using augmented reality (AR), and digital sketching (DS) as dynamics, hybrid and ubiquitous visualization systems of urban solutions designed inside of an architecture master education. We will discuss about the main advantages and disadvantages perceived by the students of applying this type of(More)
Introduction: Postoperative small bowel or colic anastomotic bleeding (PSCAB) is often a mild complication and is generally treated by a conservative approach. Other therapeutic options are surgery, endoscopic management and angiographic embolization.
