Facebook groups have been used formally or informally in educational contexts all over the world. These groups allow users share texts, videos, images or files. However, in these groups, when new posts are shared, previously shared posts go below, if they are not liked and commented constantly. As a result, group members have to make an extra effort to reach those posts. That is, it is difficult for people to access the group posts later, and eventually information quickly consumed and goes out of members' sight. Considering the prominent use of Facebook in learning environments, this issue becomes a major problem. For this reason, this study aims to suggest post design principles, which allow students to search and access information easily and fast, after examining the information search behaviors of graduate students in an informal Facebook group environment named "Botegrad" and the keyword recommendations of other graduate students for the selected posts. This study aims to answer: how Facebook group posts should be structured so that students can find and reach the information easily, effectively and fast? Botegrad is a community-based Facebook group consisting of the members who are the graduate students studying at the Department of Computer Education and Instructional Technology at a state university in Turkey.
