Buen material porque motiva a la exploración, siempre es necesario motivar al estudiante a que reconozca la geometría en el mundo que lo rodea.

Sitio web que presenta contenidos asociados con matemáticas y que cuenta con aplicaciones en java que nos permiten indagar y explorar sobre distintos temas asociados a esta disciplina.

Recomendable para todo estudiante que este cursando algún curso relacionado con geometría, desarrolla el sentido exploratorio y la indagación y la comprensión concreta de la figura que se le está dando algún trabajo.

La pagina web es confiable y cuenta con todos los temas detallados y destacados claramente, es una buena herramienta utilizada para que los docentes la conecten con sus exposiciones cotidianas.

El amterial es confiable y estan tratado de buena forma los aspectos teoricos.

Para principiantes en geometría, requiere el acompañamiento de algún, tutor, docente o persona especializada en la asignatura.

I spent about 30 minutes reviewing and experimenting with the applets available. Most of the simulations model concepts that I would like to show my students. I wish I had the ones dealing with angles inside circles about a month ago. I would have used them in my lessons. I think that these would be best used as a demonstration to spark conversation about concepts. They are not something that my students would use for long periods of time. They are just simple simulations to explore a concept and develop a conclusion.

Technical Remarks:

The applets are very simple and easy to use. For most of them you just click and drag vertices where you want them.

i found this site very interesting. i am doing my midterm on the pythagorem
theory so this information was very useful to me. Then i looked into the
pythagorean triples. i enjoyed learning the different sets that would produce a
right angle.

i think this a very interesting tool to have. this is going to help me with my
midterm and i will enjoy looking over the rest of these sites.
Used in course
