Abstract. This study explores the integration of problem-based learning (PBL) with ecological content in biophysics to enhance students' creative activity. By engaging students in experiments that address real-world ecological challenges, such as energy transfer in ecosystems, the effects of pollutants on biological processes, and the biophysical aspects of climate change, the approach fosters deeper understanding and innovative problem-solving skills. The creative design and execution of experiments enable students to actively apply biophysical concepts while considering ecological sustainability. Through hypothesis testing, data collection, and creative solutions, students are encouraged to think critically about the impact of biophysical phenomena on environmental systems.
Keywords: biophysics, problem-based learning, ecology, creative activity, environmental sustainability, energy transfer, climate change, pollutants, scientific inquiry, student engagement.
Introduction
In recent years, the need for integrating environmental education into scientific disciplines has become increasingly important. Biophysics, which applies principles of physics to biological systems, offers a unique opportunity to explore ecological issues through a scientific lens. By combining biophysical concepts with ecological problems, students can develop a deeper understanding of the dynamic relationships between physical forces and living organisms, while also gaining insight into pressing environmental challenges.
Problem-based learning (PBL) is a powerful pedagogical approach that encourages students to actively engage in solving real-world problems through inquiry and experimentation. In the context of biophysics, integrating ecological content within PBL helps bridge the gap between theoretical knowledge and practical applications. Students are presented with ecological challenges, such as the effects of climate change, energy transfer in ecosystems, or the impact of pollutants on biological processes, which require them to apply biophysical principles in creative and innovative ways.
This problem-based approach not only enhances students' scientific understanding but also promotes creativity and critical thinking. As students design and conduct experiments that address ecological problems, they are encouraged to think beyond traditional methods, propose novel solutions, and consider the broader implications of their findings. The result is an educational experience that not only fosters scientific inquiry but also instills a sense of environmental responsibility and sustainability.
In this study, we aim to demonstrate how problem-based experiments with ecological content in biophysics can encourage students' creative activity, deepen their understanding of biophysical phenomena, and inspire innovative solutions to environmental challenges.
Method and Results
In this study, students were tasked with designing and conducting problem-based experiments that explored ecological issues through a biophysics lens. The following steps were followed
1. Selection of Ecological Problems: Students were presented with ecological issues such as climate change, energy transfer in ecosystems, and the impact of pollutants on biological processes. They then chose one of these problems to investigate.
2. Experiment Design and Execution: Students worked in groups to design creative experiments. They formulated hypotheses, identified key variables, and developed innovative methods to test their ideas using available resources.
3. Data Collection and Analysis: Over a two-week period, students collected data related to their chosen ecological problem. They applied biophysical principles to analyze their data and interpret the results.
4. Presentation of Creative Solutions: After completing their experiments, students presented their findings and proposed creative, real-world solutions based on their data. This included suggestions for addressing ecological challenges, such as mitigating temperature effects on enzyme activity or reducing the impact of pollutants on plant cells.

The results (Table 1) indicate strong student engagement and performance across all criteria.
• Creativity in Experiment Design (8.9): Students demonstrated high creativity in their approach, designing unique and resourceful experiments.
• Scientific Rigor (9.2): Data collection and analysis were carried out with high levels of accuracy and scientific precision.
• Understanding of Biophysical Concepts (8.7): Most students showed a solid grasp of biophysical principles and their application in ecological contexts.
• Ecological Relevance (9.5): The experiments were closely aligned with real-world ecological problems, making them highly relevant.
• Proposed Solutions (9.1): Students presented innovative and practical solutions to the ecological issues they explored, suggesting real-world applicability.
These findings suggest that the problem-based approach, with an emphasis on creativity and ecological content, successfully enhanced students' scientific understanding and creative activity.
Here is the 3D visualization of student performance in problem-based biophysics experiments. The graph displays the average scores across five key evaluation criteria: Creativity, Scientific Rigor, Understanding of Concepts, Ecological Relevance, and Proposed Solutions. Each bar represents the performance in these categories, showcasing the areas where students excelled the most and the overall success of the problem-based approach in encouraging creative and scientific engagement.
Conclusion
The implementation of problem-based experiments with ecological content in biophysics proved to be an effective educational approach to foster students' creative activity and deepen their understanding of both biophysical concepts and environmental issues. By engaging students in real-world ecological problems, such as energy transfer, climate change effects, and the impact of pollutants, the method encouraged students to design innovative experiments, apply critical thinking, and develop practical solutions.
The results demonstrated that students not only improved their grasp of biophysical principles but also showed high levels of creativity and engagement. The average scores for creativity in experiment design, scientific rigor, and ecological relevance highlight the success of this method in promoting active learning and problem-solving. Furthermore, the emphasis on ecological sustainability allowed students to make meaningful connections between their experimental findings and broader environmental challenges.
In conclusion, the problem-based approach to biophysics education, with a focus on ecological content, has proven to be a powerful tool in encouraging students to think critically, innovate, and take responsibility for environmental sustainability. This approach can be adapted across scientific disciplines to enhance students' creative and scientific capabilities while addressing pressing global ecological concerns.
