This situation indicates how important these studies are. To keep up with the pace of the era, the studies on computer assisted education and language education have become very important and lots of scientific studies have been published. There are many theses among these scientific research studies. The aim of this research is to examine the tendencies of the theses written in the field of computer-assisted English education.
