Learning to Teach with Technology Studio
Probability Explorer 2.0 - H. Stohl | Pulchritudinous Primes
LEARNING TO TEACH WITH TECHNOLOGY STUDIO (LTTS)
ONLINE PROFESSIONAL DEVELOPMENT OPPORTUNITY
http://ltts.org/
LTTS is offering an online professional development module
entitled "Scientific Graphs and Charts: How can my students
use technology to organize and present their inquiry data?"
In this module, teachers design and plan a science inquiry
unit that will teach their students how to organize and
present their own inquiry data using computer software
programs.
http://www.ltts.org/system/catalog/primary/cat_module20.html.
The course will start on October 1st and it will require
about 25 hours of work. LTTS is looking for people who:
- teach upper elementary or middle school
- feel that a science education professional development
course would be helpful to them
- have regular computer and Internet access
- know how to use email and how to attach documents to
email messages
- have not completed an LTTS course in the past twelve
months
If you are interested:
1. Send an email message to ltts@indiana.edu, expressing
your interest in participating in the professional
development opportunity and telling your name, email
address, and grade level you teach.
2. Go to http://ltts.org and register as a member of LTTS
so that you can be enrolled in the system in time for
the October 1st start. If you are already a registered
member of LTTS, you do NOT have to re-register, though
you may want to verify that your registration
information is up-to-date.

PROBABILITY EXPLORER 2.0 - Hollylynne Stohl
http://www.probexplorer.com/
Probability Explorer is an open-ended learning environment
for representing data in multiple ways. This Windows download
engages students in designing, simulating, and analyzing
results of probability experiments.
Data are represented in Probability Explorer with randomly
generated icons that can be sorted, stacked (in a pictograph)
or lined up in the sequence in which they occurred. A Pie
Graph (relative frequency), Bar Graph (frequency), and Data
Table (counts, fractions, decimals, and percents) are also
available to display results in both static form as well as
changing dynamically during a simulation.
Demo version available for download
http://www.probexplorer.com/demo.html
All features are available in the demo, except the ability
to save and print. In addition, in any given experiment the
number of trials allowed is limited to 500
