## 5 Conclusions  
This study examined the efficiency of different methodologies for multimedia teaching materials presentation in distance learning. The findings show that the appropriate selection of the methodology of teaching materials presentation results in more efficient learning.  
The important aspects of knowledge acquisition in distance learning are described by the cognitive load theory. Considering that, this study emphasizes that the segmentation of multimedia materials in the learning process may improve learning by reducing cognitive load and increasing the quality of the participants' knowledge. The findings indicate that the effectiveness of teaching materials and learning efficiency are higher if the materials are presented in multimedia segments, with shorter intervals between them and with the use of practice questions. In this manner, students' prior knowledge is gradually expanded, while working memory is used optimally by processing materials in segments. The successive accumulation of prior knowledge is, thus, accomplished, and the learning process becomes more effective.  
Based on experimental results, it can be concluded that the usage of practice questions as an instructional element increases student achievement and gives better results if it is combined with the principle of segmentation multimedia teaching material. A subjective analysis of the efficiency of learning, achieved with the application of these two methodologies of linear multimedia presentation of educational materials, was also carried out. The QoE assessment shows that students are more motivated and interested in learning if the S-LM methodology is applied. Finally, it can be concluded that the methodology of presentation in the form of multimedia sequences, with intervals or pauses between them and using practice questions, gave better results in terms of the presented content effectiveness, the efficiency of the learning process, and the students' QoE with the learning process. The proposed methodology can be very useful in designing and presenting multimedia materials in the microlearning approach in distance education. The improvement in learning outcomes based on the proposed methodology influences distance learning efficiency, which is especially important in situations such as the COVID-19 pandemic.  
Future research is planned to explore the efficiency of multimedia teaching materials presentation in segments, with intervals between them, during which advertising, educational, or entertainment materials are inserted. Demographic factors that influence the results should be investigated in detail. We will extend this research to include wider segments of the population. As continual professional development courses are a common educational possibility for students and working professionals, they may serve as a basis for further testing.
