This study presents a compilation of 24 cases involving general aviation (GA) pilots’ weather encounters over the continental U.S. The project team interviewed pilots who had experienced a weather encounter, and we examined their backgrounds, flight experience, and weather encounter details. Results from meteorological data analysis for each weather encounter were consistent with findings of larger GA weather accident studies in terms of the types of hazards encountered and flight phase during which the encounters occurred. Investigation of pilot weather products and the sources from which they were obtained revealed a lack of uniformity of pre-flight data sources and ...


Assessing The Effectiveness Of An Education And Training Module For General Aviation Pilots On The Use Of Nexrad-Based Products In The Cockpit, John Lanicci, Erin Roberts, E. Blickensderfer Jun 2015

Assessing The Effectiveness Of An Education And Training Module For General Aviation Pilots On The Use Of Nexrad-Based Products In The Cockpit, John Lanicci, Erin Roberts, E. Blickensderfer

John M Lanicci

Numerous studies over the years have documented the need to improve meteorological education and training for General Aviation (GA) pilots. With the advent of readily available aviation weather hazard products for real-time pilot use on the flight deck, there is now a lack of education and training on the proper interpretation and usage of these products. Data-linked NEXRAD is a good example of a currently available real-time product that is very popular in the GA community, but lacks a coherent understanding of its proper usage in pre-flight planning and in-flight operation.

Proper usage of NEXRAD in the cockpit should require ...

Supporting Teacher Orchestration In Ubiquitous Learning Environments: A Study In Primary Education, Juan Muñoz Cristóbal, Ivan Jorrín Abellán, Juan Asensio Perez, Alejandra Martínez Monés, Luis Prieto, Yannis Dimitriadis

Ivan M. Jorrín Abellán

During the last decades, educational contexts have transformed into complex technological and social ecologies, with mobile devices expanding the scope of education beyond the traditional classroom, creating so-called Ubiquitous Learning Environments (ULEs). However, these new technological opportunities entail an additional burden for teachers, who need to manage and coordinate the resources involved in such complex educational scenarios in a process known as “orchestration”. This paper presents the evaluation of the orchestration support provided by GLUEPS-AR, a system aimed to help teachers in the coordination of across-spaces learning situations carried out in ULEs. The evaluation, following an interpretive research perspective, relied ...

Coming Down To Earth: Helping Teachers Use 3d Virtual Worlds In Across-Spaces Learning Situations, Juan Muñoz Cristóbal, Luis Prieto, Juan Asensio Pérez, Alejandra Martínez Monés, Ivan Jorrín Abellán, Yannis Dimitriadis

Ivan M. Jorrín Abellán

Different approaches have explored how to provide seamless learning across multiple ICT-enabled physical and virtual spaces, including three-dimensional virtual worlds (3DVW). However, these approaches present limitations that may reduce their acceptance in authentic educational practice: The difficulties of authoring and sharing teacher-created designs across different 3DVW platforms, or the lack of integration of 3DVWs with existing technologies in the classroom ecosystem (e.g., widespread web-based learning platforms such as Moodle, or mobile augmented reality applications). Focusing on a specific kind of 3DVW (virtual globes, such as Google Earth, used like 3DVWs), we propose a system that enables teachers to deploy ...

Wikis For Group Work: Encouraging Transparency, Benchmarking And Feedback, Amir Abdekhodaee, Dini Kourosh, Farnaz Modarres, Anne-Marie Chase, Bella Ross

Dr Anne-Marie Chase

Education delivery models and approaches are undergoing radical change. The traditional knowledge exchange model whereby an educator imparts knowledge to students may not be best placed to develop essential skills for the 21st century (Griffin, McGaw, & Care, 2012) and is being challenged by models that encourage knowledge creation by students. Using a wiki to facilitate group work may provide students opportunities for collaborative learning (Blumenfeld, Marx, Soloway, & Krajcik, 1996), knowledge sharing and construction (Elgort, Smith, & Toland, 2008), and skill development. Wikis allow individual contributions to be traceable thereby increasing individual accountability in group work situations. Wikis can furthermore be monitored ...
