The obtained results proved that irradiation technology can actually raise the percentage of chemical compounds that would increase the biological activity of the essential oil. This allows to increase the potential of the plant studied and its biological effectiveness, also the irradiation process has proven the ability to raise the quality of the chemical composition both in terms to reduce the risk of contamination it can be microbiological, physical, and chemical of one of the most abundant medicinal plants in northern Morocco.

The data was collected using a 37-item questionnaire covering the following variables: the teaching methods adopted, the preferred pedagogical approaches, the teaching material used, and the teaching difficulties encountered. The study fits under a descriptive correlational design. The most used teaching methods were the teacher-centred oral methods (dialogue and demonstration method) lacking learner-centred activities (working in small groups, discovery method). The least used ones were laboratory experiments ...
