Περίληψη (Αγγλική μετάφραση) In the context of the present study, a comprehensive intervention in supplementary distance education was designed, implemented, and evaluated for primary school students in the Skills Workshops course, under the theme: "The Olive Tree as an Element of Natural, Local, and Global Cultural Heritage." The intervention was carried out with 5th and 6th grade students of a small multi-grade primary school. For the development of the educational material, the methodology of distance education was applied, along with theories, principles, and instructional design models proposed by experts in the field, including the West–Lionarakis model and Mayer’s Cognitive Theory of Multimedia Learning. The material was created using the open-source tool H5P and integrated into the platform students.edivea.net. To evaluate the educational material, qualitative research was conducted with a sample consisting of 4 experts in distance education, 2 teachers, and 6 students. Three questionnaires with both open-ended and closed-ended questions were used as data collection tools: one for the distance education experts, one for the teachers, and one for the students. The results of the expert evaluation indicated that the educational material is scientifically grounded and well-supported by the literature. It presents the subject matter in a simple and understandable way, includes interactive and engaging elements, supports learners in their study, and guides them in self-directed learning. Furthermore, it is user-friendly, interesting, and original, provides continuous feedback, and offers opportunities for self-assessment. It clearly incorporates the purpose and expected learning outcomes, to which it fully responds, while remaining consistent with the Cognitive Theory of Multimedia Learning. Teachers evaluated the educational material positively, finding it interesting, appealing, analytical, and explanatory, with clear instructions and a user-friendly structure that facilitates study. They noted that it contains sufficient, well-documented content without unnecessary information, rich visual resources, and activities that enhance comprehension. Key strengths identified included its interactivity, the explanations through images and videos, and the summary videos provided at the end of each unit. They stated that they would use it in practice, suggesting only minor improvements, such as adding group activities for collaborative learning and including more narration and images with less text for younger grades. All students reported that they liked the way the material was presented, considering it well-crafted, easy to use, understandable, and useful, as it helped them learn more about the olive tree and better understand the lesson. They highlighted that the experience was more interesting and enjoyable, allowing active participation, internet use, and clear guidance. They especially appreciated the interactive videos, the glossary explanations, the teacher-character avatar, and the exercises. Most students suggested no changes, while a few proposed minor adjustments such as changing the colors, improving site access, enhancing audio in one video, and modifying the initial avatar.
