The study addresses the problem of enhancing student motivation in learning cause-and-effect relationships in nature through the implementation of practice-oriented educational tasks and illustrative materials. Methodology and Methods. A pedagogical experiment was conducted with control and experimental groups, where active teaching methods were applied in the experimental group through the performance of practical tasks designed to identify cause-and-effect relationships using illustrative materials. Results. It was established that meaningful and didactically well-structured learning activities play a crucial role in fostering student motivation by enabling learners to engage consciously with educational content in real-life contexts. The experimental group demonstrated significantly higher student engagement compared to the control group, showing greater interest in practical activities and higher motivation to succeed. Successful completion of practice-oriented tasks instilled a sense of achievement and self-confidence in students. Scientific novelty. The effectiveness of practice-oriented tasks as a motivational tool that promotes active and conscious learning in studying cause-and-effect relationships in nature has been proven. Practical significance. The developed approach can be applied to improve the quality of the educational process, achieve defined learning objectives, and sustain increased student motivation for research-based and project-oriented learning activities.
