The purpose of this study was to examine whether video-assisted instruction effectively enhances science content vocabulary learning of English Language Learners (ELLs). Video medium was used as the treatment factor for providing ELLs with the comprehensible input (Krashen, 1985). Fifteen fourth grade Hispanic ELLs were randomly assigned to either the experimental group with video treatment, or to the control group with traditional textbook instruction without video exposure. Results indicated that ELLs, who received video instruction, did not score significantly higher on vocabulary achievement than those who received traditional textbook instruction without video exposure. Thus, the outcome of the study does not support a positive impact for using video-assisted instruction on ELLs' science vocabulary development since there was no significant gain by the video group over the non-video group.Chapter 4 Overview 4th Grade Earth Science Unit Pacing Guide Day 1 Scientists know that the Earth has changed over time, and continues to ...
