Social annotation platforms such as Perusall and Hypothesis are emerging as another tool to use in instruction. These tools allow students to anchor comments and responses to assigned text readings, asking questions and reacting to peers’ comments. When coupled with Open Educational Resources (OER), these tools can significantly reduce student total cost for instruction while at the same time increasing reading comprehension and knowledge construction through peer interaction. The full description below provides references demonstrating the effectiveness of the annotation tools to a general population. There is a paucity of descriptions of the effects of these programs at predominantly Hispanic institutions. The current exploratory analysis took place in such an institution. Implications for our student bodies and students for whom English is a second language (L2) will be discussed.
