Cugnology is the cuddly friend of technology. We are a group of educators that want to help you use technology in your lessons. We want you to come to us in the planning stages of your lessons, and we can help make them streamlined, select the proper software and hardware tools, to make you an independent technology user; particularly bringing technological tools into the hands, minds, and lives of your students.
