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”.

Climate change: In their old age, trees still accumulate large quantities of carbon

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
