Recruitment Invitation for Climate Time Line Testing


We would like to invite you to assist us in the evaluation of a new website entitled, "The Climate Timeline Information Tool" or CTL which has been in development by educators and scientists at the University of Colorado and NOAA’s Paleoclimatology Program. The basic aim of the Climate Time Line is to provide an online resource that may help in the understanding of climate processes and events at varying time scales.

Your participation in this evaluation will be most helpful in providing us with feedback and insights into what works and what doesn’t. Your responses will assist us in improving the site as a tool for conveying information about climate change and related social and environmental issues.

Your participation in the evaluation would consist of taking a short quiz that is designed to provide us with a general sense of your understanding of processes and events relating to climate variability. After taking the quiz, we would like you to take as much time as you’d like visiting the CTL website, and when you are finished, we would like you to retake the quiz and fill out a short survey which asks questions about your impressions of the website.

Here are the steps we would like you to take as part of our evaluation of the Climate Time Line:

1) Pre-Quiz: The online quiz is located at and the login code is "ctl". You will be asked to enter your name, email address and ID number or password. Unless you are instructed to do otherwise, you may leave the ID number/password blank. All this information and results will be kept strictly confidential.

2) Once you have taken the quiz, visit the website which is at

3) When you are finished, please take the quiz again using your same name and email address.

Additional feedback may be sent to

Your involvement with this evaluation of the Climate Time Line is very much appreciated, and the confidential results of the information you provide will assist us greatly in evaluating the content and useability of the website.
