The CLEA projects are extremely useful in the classes I run at the former site of the Royal Greenwich Observatory in Herstmonceux, East Sussex. Thank you for preparing them!

Cameron Bell, Mooroolbark College, Mooroolbark , Victoria, Australia

This project is fantastic. It is helping me change the way teachers think about teaching astronomy. It is less a history lesson and now a more investigative approach and helps me communicate the concept of scientific modelling.

Jose H Pena, UNAM, Mexico, DF, Mexico

I teach at the University of Mexico a course in observational astronomy.  I have used clea's practices in photometry and spectroscopy of the pleiades, combined with the data available and my students have found these practics very stimulating and interesting. You have done a great job.

B A Kagali, Bangalore University, Bangalore, India 

Your exercises have been very useful to us in teaching astronomy to our M.Sc students.Thanks a lot.

I found CLEA to be very useful in teaching astronomy.

Dr. Antonio Mario Magalhaes - Instituto Astromonico e Gerfisico
I've just reached your page while looking for laboratory exercises in Astronomy. I'm already impressed by what I saw and I'm eager to try out some of the material. Congratulations for the job!

Bruce Dawson and Andrew Smith at University of Adelaide:
We have received your software and manuals and are very impressed.  We intend to use the materials in our freshman Astronomy class.  While we think the student manuals are well written.

Dr EJ Wolstenholme at Christ's Hospital in Sussex:
We are most impressed with the CLEA software and hope to include it in a new physics module in our sixth form course.

C. E. Alissandrakis at the University of Ioannina in Greece:
I just tested your spectral classification lab and found it very interesting. Congratulations!

Dr. Grant Christie of New Zealand:
Thank you for sharing your wonderful contributions to astronomy education.

David Block of South Africa:
Firstly allow me to congratulate you on one of the most useful astronomy lab exercise sites I have ever visited on the WWW!  I lecture in South Africa at the University of the Witwatersrand, Johannesburg, where we have some 20K students.  I will have no hesitation in informing my applied math/physics students of your extremely insightful and well designed exercises, some even including slewing in the animations!....My students are ENTHRALLED by your CLEA software. Their eyes were  agog with the PHOTOMETRY exercise... opening the dome.... selecting a filter, etc etc!!

Dr. Nigel Marshall at Queen Mary School in Lytham, UK:
I downloaded the spectral analysis software for use in my school. It is excellent - many thanks.  Cheers and keep up the good work.

Thank you for this wonderful educational material.  My students and I will enjoy using it.

Jeroen Homan of the Netherlands:
I wish you all good luck with your work, because I think it is very important what you do. I searched a long time for good educational astronomical software, but it is hard to find. You can imagine how glad I am having found the CLEA stuff.

Angel Rafael Lspez Sanchez at Granada University, Spain:
I'm a Physics student in Granada University, and I'm very interesting in CLEA exercises in Astronomy. I'm very interesting in practical astronomy for secondary student (14-18 years), because I give short courses.  Thank you very much for everything, and  congratulations for these exercises!

Cao Jun of Beijing, China:
Thank you very much. I am very happy to become a user of project CLEA.

I have downloaded the CLEA software for PC and find then very instructive and well done.  I hope to use some of them in my introductory astronomy course.

 Dr. Bob Nelson at the College of New Caledonia, Canada:
Might I say that I find your CLEA software innovative and well-written.  I plan to incorporate at least some of the titles into our astronomy program.

Graham Armstrong at Woodbridge District High School in Tasmania, Australia:
Thanks for your wonderful set of practical labs in astronomy I have used a number of these labs with my students and found them and found them to be an excellent educational resource.  I have developed a number of lessons around them and from the reports of my students they seem to rate as some of the most interesting activities in Astronomy and Physics.  My students have been able to relate these labs to their practical astronomical observations and I have a marked improvement in the quality and accuracy of their observations.  Once again thankyou very much.

Neil Charlton of  Waterlooville, United Kingdom:
I teach the equivalent of high school physics in England.  This software is definitely the way to go - superb!

Claudio Costa of Roma, Italy:
