The quality and relevance of the Semiconductor Technologies course were evaluated through three complementary assessment grids completed by different stakeholders.
The first evaluation grid was completed by a faculty member from the Higher School of Applied Sciences of Tlemcen (ESSAT).
The second evaluation grid was completed by a faculty member from the National Higher School of Telecommunications and Information and Communication Technologies of Oran (ENSTTIC Oran). This external evaluation provides an additional academic perspective on the scientific content, pedagogical coherence, and relevance of the course to the targeted field of study.
The third evaluation grid was completed by a student who had previously attended the Semiconductor Technologies course. This student evaluation provides feedback from the learner’s perspective, particularly regarding the clarity of the explanations, organization of the course, accessibility of the content, and its usefulness for understanding semiconductor concepts.
Together, these three evaluation grids provide complementary perspectives from an internal academic evaluator, an external academic evaluator, and a former student, contributing to a broader assessment of the quality, pedagogical relevance, and effectiveness of the Semiconductor Technologies course.
