The purpose of the study was to investigate the impact of using E- Scaffolding for developing Faculty of Education STEM students' questioning skills and learning engagement. The researchers co- taught "English for STEM 1" in the first term of the academic year2022-2023. The present study adopted the pre-experimental research design. Thirty nine students were enrolled at the first year in STEM program; (16) were specialized in Chemistry and (23) others were specialized in Mathematics. They participated in the study and acted as one study group. To achieve the objectives of the study, the researchers designed a questioning skills test and a learning engagement scale.  The researchers developed a teacher's guide adopting E-Scaffolding. Students received twelve sessions; one hour a week with an online extension. The findings showed a considerable statistical improvement favoring the post testing of the questioning skills test and the post administration of the learning engagement scale.
