You will find yourself in a virtual room. An organizer will be there to greet you, starting about half an hour before the event.
If this is your first Elluminate event, consider coming a few minutes earlier to check out the technology. The room opens half an hour before the event.
National Library of Virtual Manipulatives (NLVM)
The National Library of Virtual Manipulatives (NLVM)
is an NSF supported project that began in 1999 to develop a library of uniquely interactive, web-based virtual manipulatives or concept tutorials, mostly in the form of Java applets, for mathematics instruction (K-12 emphasis). The project includes dissemination and extensive internal and external evaluation. The NLVM is a resource from which teachers may freely draw to enrich their mathematics classrooms. The materials are also of importance for the mathematical training of both in-service and pre-service teachers.
The NLVM was extended and refined through an NSF project called the
. The eNLVM project developed interactive online learning units for mathematics, called eModules. eModules target specific learning outcomes, provide sequences of interactive activities, and include online assessments. As part of the eNLVM project teams of mathematicians, classroom teachers, math educators, instructional designers, graphic designers, and programmers worked together to iteratively design, develop, field test, and revise eModules. The eNLVM project also developed a learning management system tailored specifically for use with interactive resources.
Models for Math
Joel's company is in the process of rolling out a new website called Models for Math. Models for Math is partnering with providers of interactive open content for math, including the
community, to provide free hosting of websites where they can author and deliver online lessons. Models for Math will offer free accounts for individual teachers that allow them to use NLVM and eNLVM materials and other open content. Models for Math will sell affordable subscription-based interactive online math websites for schools and districts. Revenue from subscriptions will allow Models for Math to continue to improve its online learning environment and to support the development of high quality interactive online content for mathematics.
