This study investigates the effect of DA on learning form and meaning of news vocabularies among Iranian EFL learners. To do this, ۹۰ students from the population of Iranian EFL learners studying English in Sadat Language Institute in Tehran, Iran were selected. A proficiency test administered and ۶۰ students selected. They were then divided into two groups as experimental and control group. Prior to the instruction, a pretest on the news vocabularies administered to both groups. The experimental group received DA treatment and the control group would not. After eight session’s instruction, a posttest was given to both groups. Students’ pre- and post-test scores compared to determine if students made any news vocabulary form and meaning development. A‘t-test’ on the mean scores of both groups indicated a significant difference between the scores of the post-tests, meaning that the DA was significantly effective in the experimental group’s learning form and meaning of news vocabularies. Findings led to the conclusion that the experimental group outperformed the control group. The product of this study can help curriculum designers; language instructors and practitioners appreciate the importance of DA and to introduce DA to students to expand their vocabulary knowledge
