Astronomy Star Project
(View Complete Item Description)This is a project I assign my students in an introductory, non-science major astronomy class. Each student is assigned one of the 25 brightest stars in the sky and they are asked to research and apply concepts they have been learning in the class to their particular star. I leave it up to them to decide the format of their final project - most do PowerPoint but some have done videos or podcasts. One student actually landed a part time job at a radio station after they heard her recording her star project! Many students tell me this is a highlight of the course!

Using Social Media (Twitter) in the Classroom
(View Complete Item Description)This handout describes how I plan to integrate social media (Twitter) into my online astronomy class. With minor modifications, it would work equally well in a face-to-face class.

Using PhotoVoice in the Classroom
(View Complete Item Description)This PhotoVoice assignment is what I use in my astronomy class to get students to prepare for the final exam. They need to find a photograph illustrating a concept covered in the course and then explain it in a paragraph. They post these on the discussion board so others in the class can read and comment as desired.
