The research attempted to investigate the effectiveness of a flipped learning-based program in developing EFL students’ speaking skills and their attitudes towards it at the Faculty of Specific Education. The sample of the study consisted of (40) students divided into two groups. One of them was a control group (n=20) and the other was an experimental one (n=20). The two groups were chosen from the 3rd year EFL students at the Faculty of Specific Education, Zagazig University. A program based on flipped learning was used in teaching the experimental group, while the regular method was used in teaching the control one in the second semester of the academic year (2017- 2018). The study instruments were (1) a speaking skills questionnaire - which was divided mainly into four dimensions including: fluency and coherence, lexical resource, pronunciation skills and grammatical range and accuracy , (2) a speaking skills test, and (3) an attitude scale. Having applied the instruments and teaching the program, data were collected and analyzed statistically using SPSS. The results of the research revealed that flipped learning is positively effective in speaking skills and attitudes towards flipped learning.
