Hypertext annotation: Effects of presentation formats and learner proficiency on reading comprehension and vocabulary learning in foreign languages

This study extends current knowledge by exploring the effect of different annotation formats, namely in-text annotation, glossary annotation, and pop-up annotation, on hypertext reading comprehension in a foreign language and vocabulary acquisition across student proficiencies. User attitudes toward the annotation presentation were also investigated. Data were collected from 83 non-English-majored university students in Taiwan in a 4-week period. Each week participants read 3 passages, each with different annotation formats as a treatment condition and one passage without annotation as a control condition. Posttests of reading comprehension and vocabulary recognition followed each passage. The results indicate that, for reading comprehension, the in-text format led to the lowest performance among all types of annotation, including the control condition. The best performance was observed in the condition where annotations were presented in the pop-up format. No interaction effect between format and proficiency was detected. For vocabulary acquisition, reading passages with hypermedia annotations significantly benefit vocabulary learning for participants of medium and high proficiencies compared with the control condition. No significant differences were found among the 3 formats. The beneficial effect, however, did not extend to low-proficiency participants. Participant feedback revealed a positive attitude toward annotations. Among the 3 annotation formats, the glossary type was considered the least preferred type by participants. Findings of the research provide insights on the design and instruction for online reading.

► Three formats of hypertext annotation are examined.
► An inappropriate format could lead to detrimental effect on text comprehension.
► The explanatory text in the annotation should relate to reader's linguistic ability.
► Students' preferences for the format may not be consistent with their performance.
