The project is entitled "Aplicación de los gráficos animados por ordenador a la enseñanza de problemas de Geología" (An application of on-line animation graphics to teaching in Geology problems), coordinated by professor of Stratigraphy Francisco Delgado Salazar, from the University of Granada (Universidad de Granada); lecturers of the department of Stratigraphy and Paleontology Agustín Martín Algarra and Juan Antonio Vera Torres have also taken part in the project.
According to the coordinator, the aim of this UGR [http://www.ugr.es] project is that “after the class where the main problems are explained, students have at their disposal such problems and other similar ones to study them through a graphic and intuitive method either from home via Internet or from the Computer Classrooms in the Faculty.”
The project arises in view of the difficulties of training students of Geology problems when studying geometric problems: stratum direction and dips, veins, faults, stratum thickness, ore body potential, palinpastic reconstructions, etc. “With this method --says the coordinator of the teaching innovation project, Francisco Delgado—we pose a standard problem to the students, give an example of principle, show the way the problem is set out to make problem solving easier and, finally, we solve it step by step, using an interactive system of animated drawings as simple as possible; we have tried to make problem solving clear. When problems are difficult or laborious, either for the number of steps or the number of lines to draw to solve the problem, we have tried to differentiate every step in a clear way by colors to make graphic reading and understanding easier.”
Probably, always according to the coordinator, one of the most frustrating matters students run into is that if they dedicate lesson time to take notes of the blackboard drawings, transparencies or any other method, it is unlikely that they get the solution to the problem, since they are busy trying to reproduce as faithfully as possible blackboard drawings, which are not very precise themselves.
According to Francisco Delgado, the student often finds illegible or uncomprehensible drawings when studying at home, rarely accompanied by an explanation. In addition, drawings taken during the class often leave a lot to be desired as for angles, dimensions, etc., except in the case of those who are handy when using the square, triangle and compass, which makes study even more difficult.
“That very feeling of frustration detected in a lot of students -says the coordinator—drove me first to provide them with photocopies of the problem solving step by step, carried out with a CAD program, and later, to turn those static drawings into animated ones to simulate teacher´s problem solving on the blackboard. The first consequence expected is that students pay more attention to understand the geometric constructions when solving problems since they know that they can consult the problem, which is stored in a hardware, on-line, than to reproduce the drawings by hand on the blackboard, with the best of intentions, but rarely with the necessary quality and precision”.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
