Hello,
I'm a learning scientist from Carneige Mellon University in
Pittsburgh, PA who is conducting a scientific study of high school
students solving on-line stoichiometry problems. I post this letter in
hopes that you (and perhaps your teaching colleagues) will encourage
your students to participate in my study.
This study is an excellent opportunity for your students to practice
stoichiometry problem solving using Pseudo-Tutors, a derivative of
Cognitive Tutors that have been used in over 2000 schools across the
United States and have been shown to improve learning in algebra and
geometry. Perhaps you might even like to use the study as an in-class
exercise and tool to reinforce your students' knowledge of stoichiometry.
The study is comprised of 9 pretest problems, 15 tutored, study
problems,and 9 posttest problems. The data collected from the study
will be used to identify the effectiveness of the Pseudo-Tutors under
several conditions.
To participate, your students simply need to go to the URL below and
register. Each subject (student) will be asked to provide a
fictitious, non-identifying login name, to maintain anonymity. The
study takes from 2 to 5 hours to complete and can be done at home,
school, or wherever the Internet is available and convenient. Your
students can stop the study (their work) at any time and can restart
by returning to the URL below and providing their login and password.
The URL containing the study is:
http://learnlab.web.cmu.edu/tutorshop/ChemConsent_Study2.html
If you'd like to try out the study before having your students
participate, please don't use the above URL, as that will generate
unusable data. Rather, you can access a "test" version of the study
at: http://pslc-qa.andrew.cmu.edu/tutorshop/ChemConsent_Study2.html.
In any case, I would love to hear from you (see my email address
below) if you'll be having your students participate.
