Teachers’ and Students’ Attitudes Towards the Case-Based Method and Student Participation and Engagement in Lower Secondary Biology Education in Rwanda

In many classrooms around the world, learning science often looks the same: a teacher stands at the front, explains a concept from a textbook, and students listen, take notes, and try to remember the facts for a test. This traditional approach treats knowledge as something to be handed down, rather than something to be discovered. However, educators and researchers have long argued that for students to truly grasp complex ideas, especially in subjects like biology, they need to do more than just listen. They need to engage with real-world problems, work together to find solutions, and see how what they learn connects to their daily lives. This shift from passive listening to active problem-solving is at the heart of a teaching style known as the Case-Based Method. Instead of memorizing definitions of diseases or ecosystems, students might be presented with a story about a local outbreak or a specific environmental challenge and asked to figure out the biological principles behind it. The question for many schools, particularly in developing nations, is whether this method works when resources are scarce, classes are large, and teachers are trained in older styles of instruction.

A team of researchers from the University of Rwanda set out to answer this question in the lower secondary schools of the Rwamagana District. They wanted to know if introducing this case-based approach would change how teachers and students felt about biology lessons, and whether it would actually get students more involved in their own learning. The researchers focused on a specific group of schools where biology is taught to teenagers, looking at how a method that relies on real-life scenarios could fit into a system that has historically favored lectures. They were not just asking if the method was popular; they were measuring whether it made a tangible difference in the classroom, specifically in how much students participated and how engaged they felt during the lesson.

To find the answers, the researchers did not rely on a single type of evidence. They gathered data from thirty-one biology teachers through surveys and interviews, and they spoke with sixty students across ten different group discussions. They also watched fifteen classrooms before the new method was introduced and again after it was put into practice. This allowed them to see not just what people said they thought, but what actually happened when the lessons changed. The teachers were trained to stop lecturing and start presenting cases—short, realistic stories about biological issues that required the students to work in groups, discuss, and solve problems together.

The results showed a clear and strong shift in the classroom atmosphere. Before the new method was used, students were often quiet, waiting for the teacher to speak. After the teachers began using the case-based approach, the level of student participation jumped significantly. The researchers observed that students who had previously been passive began to speak up, share their ideas, and work collaboratively with their peers. The feeling of engagement in the room changed from a state of waiting to a state of active involvement. Teachers reported that the method helped students understand difficult concepts better because they were connecting the biology to real situations they could recognize. For instance, instead of just reading about how a disease spreads, students discussed a specific case of an outbreak in their community, which made the science feel immediate and relevant.

Both the teachers and the students expressed very positive attitudes toward this change. Nearly all the teachers surveyed agreed that the method improved how well students understood the material and helped them apply what they learned to real life. They noted that it fostered teamwork and communication skills, which are essential for the modern world. The students echoed this sentiment, telling the researchers in their group discussions that the lessons felt more interesting and less boring. They said that working in groups allowed them to learn from each other and gave them the confidence to speak up. One student noted that discussing real-life scenarios made the difficult concepts easier to remember. The data confirmed that the method was not just a nice idea but a practical tool that made biology lessons more meaningful.

However, the study also highlighted that this success did not come without hurdles. The researchers found that while the method worked well, it faced real-world constraints. Teachers mentioned that preparing these case-based lessons took a lot of time, and they often struggled to manage the discussions when there were too many students in a single room. Some teachers felt that the large class sizes made it hard to ensure every student got a chance to participate fully. There were also concerns about a lack of resources, such as enough materials to support the group work. Despite these challenges, the overall picture was one of success. The researchers concluded that the case-based method is a powerful way to teach biology in this context, aligning well with the country's goal of moving toward a curriculum that focuses on skills and competence rather than just memorization.

The study suggests that for this approach to reach its full potential, schools need to support teachers with more training and better resources. Teachers need time to prepare these complex lessons and strategies to handle large groups effectively. If these supports are put in place, the case-based method could transform biology education, turning it from a subject of rote memorization into a dynamic space where students learn to think critically and solve problems together. The findings from Rwamagana offer a hopeful glimpse into how education can evolve, proving that even in challenging environments, a shift toward active, student-centered learning can lead to deeper understanding and greater engagement.
