Title: significant figure applet
Post by: lookang on January 07, 2009, 04:38:16 pm
Hi Prof !!

Any idea how to teach significant figure in a meaningful activity that EJS can make?



This is the most popular java applet on significant figure.
But the teaching approach is more drill and practice, I was thinking about a more powerful way to allow students to explore.

 
reference:

My initial idea.

1. box for learner to key in values ( types real numbers, scientific notation )
2. EJS logic(s) evaluate the input and display the correct number of significant figures.

doesn't seems to be a good and useful applet to make, do you have an idea(s) to add as well? ;D

i found this

(http://education.ti.com/images/rightcolumn/products/apps/scitools84_L.gif)http://education.ti.com/educationportal/sites/US/productDetail/us_scitools_83_84.html

think they have already come up with a great way to explain significant figure embedded in     
Science Tools App for the TI-83 Plus and TI-84 Plus Families.

think forget it, Texas (http://education.ti.com/images/webelements/pix.gif) have a great teaching strategy through use of their calculator.

in my opinion, this is the best way.  Any way i can make one calculator emulator using EJS from  open source codes in Javascripts etc ?

There is a Function(TextField) GUI element in EJS, that user can input formula and EJS will evaluate it.
You should be able to create a scientific calculator with EJS.
Try it by yourseld first. If you really have trouble, then I will help you!

any scaffolds or examples to get inspiration from?

i have little knowledge in scientific calculator making thus can't think of a solution to do it efficiently where i can draw help from codes all in the net as open source.

need a starting guide, then once i start doing, i will have a better idea what i want, what i don't know etc.
