Provide a syllabus. Let students know what is expected of them by writing and posting a syllabus to the on-line classroom. List objectives for the class and what each student should learn as well as when assignments and projects are due. Post your contact information in the syllabus as well so students know how to get a hold of you.
Develop a supply list. Draft a list of art supplies students need to complete the projects and tasks covered in your on-line art class. Provide links to on-line art suppliers and retailers that sell the products and supplies students need. Inform students of dates when they need specific supplies if not all supplies are required on the first day of the course.
Use video lectures. Create lectures and demonstrations of main topics you plan to cover in your on-line art class. Using a webcam, record yourself giving the lecture or demonstrating how to complete a drawing, sculpting or art technique. Position your webcam to record only the paper or canvas you're drawing on as this makes it easier for students to see exactly what you are doing. Post the video lectures to the on-line classroom, and encourage students to view them and use them when mastering new techniques.
Communicate via Skype. Set up a time each week to meet with students using Skype. Encourage them to ask questions or review art techniques they are struggling with during this time. Using Skype allows you to view their work and techniques while they also have the opportunity to see you demonstrate a technique again. If on-line students live nearby, encourage them to drop in during your office hours to get one-on-one instruction.
Mail or scan artwork. Require students to send you completed art projects via the mail as this allows you to see them up close and accurately judge their techniques and abilities. If teaching an on-line drawing, painting or sketching class, encourage students to scan their art into a digital file on their computer and submit it instead. This saves on mailing costs as well as on time.
