Hi Looking for Advise - Online Masters in curriculum design

Hi - I am looking for advise/suggestions. I would like to go back to school for a masters in curriculum design with a emphasis in online education. I am looking for a program that is offered completely online. I currently have a bachelors in Business Information Systems. I want to do a career change. I recently started taking classes for a certificate from a program called teaching online utilizing technology and it turns out I really enjoy the course so I thought it would be a better investment of my time and money if I got my masters instead of finishing the certificate program.
Does anyone have any suggestions where I can get a masters in curriculum/instructional design with a emphasis on technology that is offered completely online.

I would appreciate any suggestions or help.
Thanks,
Edith
