Internet and Mathematic Education (E-Learning objects and tools for Mathematics Education)
This paper analyzes some e-learning objects and didactics tools for improving mathematics education. The learning objects and tools analyzed are Videos, Applet Java, Geogebra, Wolfram|Alpha with his Widgets, Google Spreadsheets and Wiris. The analysis has been based on the parameters considered more suitable for didactics of mathematics. Such parameters are: interactivity, shareability, availability, applicability and feasibility. The paper presents a brief description of how the didactics is changing with internet, in particularly the didactics of the mathematics. It then shows the objects and tools selected with some application examples. Finally, it illustrates an comparison of the objec…
Dizziness and vertigo in a department of emergency medicine.
Dizziness is a common and vexing diagnostic problem in emergency departments. The term is rather undefinite and often misused, but can in practice be classified into four categories: fainting, disequilibrium, vertigo and miscellaneous syndromes. Vertigo is the most common category of dizziness. Classification of vertigo can be based either on chronological criteria (acute, recurrent or chronic vertigo) or on topographical criteria (peripheral or central vertigo).
