A graphic and intuitive method allows UGR students to solve Geology problems on-line

16.01.2007
Some of the objectives of the Teaching Innovation project are to substitute the difficult blackboard drawings for high-quality drawings, easy to arrange in sequence; replace the static system of book exposing with a more dynamic and interactive system; free students from taking notes and allow them to pay more attention to the class; provide students with an electronic book with an interactive system for a friendlier learning than the clasic book with static figures, etc.

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”.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
