This research study reports the effects of using interactive graphical and technological strategies - IGOs in the reading comprehension process of EFL Chilean students. Reading is an essential skill for EFL learners. Consequently, helping students to develop strategies to improve their level of reading comprehension becomes vital. This quasi-experimental study reports the findings on the impact of IGOs used to teach EFL reading comprehension skills to a group of Chilean engineering students. The IGOs strategies: cause and effect and advantages and disadvantages were tested. The information collected in the pre-test and post-test showed that the experimental group increased their performance compared to the control group. Thus, by using IGOs Chilean engineering learners enhanced the level of EFL reading comprehension skills.
