Two instructor’ model, called as “the first and second instructed model” was implemented in these courses.
This model was developed by the researchers (Selvi and Çardak, 2009). The first instructor gives voice and text
messages and carries out visual contact with the classroom. The second instructor also joined the virtual
classroom and as a mentor s/he used only text messages to follow the virtual classroom, gave feedback, provided
extra information, reinforcement, asked questions, and shared some ideas with the first instructor and the
students. Some of the learning and teaching activities such as homework, group and individual studies and
discussion of the topic of week were realized on the Form of Discussion setting so that 24 hours reflection was
possible during the day except for the midterm and final exams of the course.
