The aim of the current study is to investigate how secondary stage students develop their EFL fluency through being exposed to an electronic program based on the inquiry-based learning context. The researcher used two social media means: Telegram and Skype. The participants were 15 secondary stage students in a governmental school for girls in Qena. An interview and a test were designed to measure the students' EFL fluency. An electronic program based on inquiry based learning was designed to develop the students' EFL fluency. The electronic program consisted of ten EFL fluency components. The obtained data was analyzed qualitatively and quantitatively. Wilcoxon test was used to calculate the effect size of the suggested program on promoting the study participants' EFL fluency. The findings revealed that the total mean scores of the participants on the post-administration of the test were higher than their total mean scores on the pre-administration of the test. In addition, the effect size of all EFL fluency components indicated that the program based on electronic inquiry based learning context had a very strong effect on enhancing secondary stage students' EFL fluency components.
