Using+eNLVM


 * Teachers will see and explore the eNLVM, looking at the current resources available for Algebra I and the possibility of creating their own.**

Many of us have seen the [|NLVM] (National Library of Virtual Manipulatives) and used them in class or recommended them to students as a way to visualize concepts. For those of us who have struggled with //**how**// to use them in a large group setting, [|eNLVM] is a good place to start.

First, the available resources are: eNLVM lessons (created by NLVM staff), the original NLVM resources, and "Teacher Published Lessons"

It is possible to Browse all of the lessons without registering for an account, although registering is very quick and easy (later in the session)

The eNLVM lessons are arranged by course. It currently seems that the middle level courses (Math 5 through Algebra I) seem to have the most lessons available. We'll be looking at [|Slippery Slope].
 * eNLVM Lessons** -



The lessons have several functions. There are sections that are purely visual, using the NLVM tools to demonstrate concepts. There are sections that are explanatory, using the NLVM tools to allow the students to explore concepts, change values, and see what happens when they "play" with those tools and concepts. eNLVM also has the ability to collect student responses, letting them compare their answers with the teacher's response, or allowing the teacher to collect collated assessment data.

This is the Prerequisites section of the Slippery Slopes lesson. When students enter answers and click "Submit Answers", they can immediately see whether their answers are correct ->

Here is the check answer page for Integer Operations (yes, I did purposely get some wrong answers just to see what it looked like!)

There are also plenty of good visuals integrated with the tools,

Both teachers and students can navigate using the drop-down menus...

Here is the final page in the unit, a place for students to show what they know...

All of this "browsing" can be done without registering. The next set of functions requires registration.

Registrations are free and easy and include the ability to save only the lessons you want to use with your classes, the ability to alter saved lessons to suit your style of teaching or the styles and levels of your students, also enables your students to log in and their work to be saved for formative or summative assessment.

Definitely check to see if your school is listed!!

Create a class because you cannot save lessons without that repository. Not all the lessons you save or edit need to be made public.

- [|About] the eNLVM project - this link includes tutorials both in "auto-playing" PowerPoint and as Flash movies. One of the tutorials discusses student usage. Another interesting piece to the eNLVM resources is that they are undergoing rigorous [|field-testing]. It is possible, even encouraged, for teachers to participate in the research and evaluation process regarding these tools.
