%0 Journal Article %T THE IMPACT OF GLOSS TYPES ON IRANIAN EFL STUDENTS¡¯ READING COMPREHENSION AND LEXICAL RETENTION %A Mohammad Taghi Farvardin %A Reza Biria %J International Journal of Instruction %D 2012 %I International Journal of Instruction %X Research has shown that the effect of marginal glosses on reading comprehension and vocabulary retention is a controversial issue. The purpose of this study was to investigate this issue among Iranian university EFL students. Three types of glosses were applied in this study: single gloss in participants¡¯ first language (SL1G), single gloss in participants¡¯ second language (SL2G), and multiple-choice gloss (MCG) in participants¡¯ second language. One hundred and twenty undergraduate students majoring in English Teaching at Azad University of Najafabad, Iran, read the texts under three conditions: SL1G, SL2G, and MCG. Afterwards, participants answered two vocabulary tests, one administered immediately after the reading test and another three weeks later. One-way repeated measures ANOVA and follow-up post hoc tests (p<.05) showed that MCG facilitated participants¡¯ vocabulary learning while reading the text more than SLGs. The results of One-way ANOVA also revealed that SL2G was the most facilitative gloss type for the participants¡¯ reading comprehension. The study illustrates how different types of textual glosses can affect both reading comprehension and vocabulary retention. Limitations and suggestions for future research are discussed. %K reading comprehension %K single gloss %K multiple-choice gloss %K narrative text %K expository text %K language learning %U http://www.e-iji.net/dosyalar/iji_2012_1_6.pdf
