Technology-enhanced Inquiry-based Learning for Sustainable Science Education: Equity, Attitudes, and Achievement in Nigerian Junior Secondary Schools: A Quasi-experimental Study

In many classrooms around the world, science is often taught as a list of facts to be memorized, a static collection of names and dates that students absorb without truly understanding. This traditional approach, where the teacher speaks and the students listen, struggles to build the kind of deep thinking and problem-solving skills needed for the modern world. To fix this, educators have turned to a method called inquiry-based learning. Instead of simply receiving information, students act as investigators, asking questions, exploring materials, and building their own understanding through discovery. However, this method faces a significant hurdle in many developing regions: a lack of reliable internet and expensive digital tools. When schools cannot connect to the cloud, the promise of interactive, technology-supported learning often fades, leaving students with the same old lectures. The question then becomes whether technology can still help students learn better and feel more confident in science, even when it must work without an internet connection.

A team of researchers in Nigeria set out to answer this question by testing a specific solution designed for classrooms with limited resources. They focused on junior secondary schools in Ibadan, a city where students often face large class sizes and inconsistent infrastructure. The researchers introduced a digital learning package called TIBLEP, which stands for Technology-Enhanced Inquiry-Based Learning Educational Package. This tool is unique because it does not require the internet. It runs on offline computers and delivers lessons that guide students through scientific investigations, offering immediate feedback and structured activities that keep them engaged. The researchers wanted to see if using this offline package could change how students felt about science and how well they performed on tests, compared to students who continued with standard, lecture-based teaching.

To find the answer, the study involved 200 students from six public schools. The researchers split these students into two groups. One group, the experimental group, spent ten weeks learning their natural science lessons using the TIBLEP software. The other group, the control group, learned the exact same topics using traditional methods, where the teacher explained concepts from a textbook and students took notes. Before the ten weeks began, and again at the end, the students took tests to measure two things: how much they achieved academically and how they felt about the subject. The researchers also looked closely at whether a student's family wealth or gender made a difference in how well the new method worked, ensuring that the solution was fair for everyone.

The results were striking. Students who used the offline technology package showed a dramatic improvement in their attitudes toward science. They became more interested, more motivated, and more confident in their ability to understand the subject. In contrast, the students who received the traditional lectures showed no significant change in how they felt about science. When it came to test scores, the difference was even more pronounced. The students using the technology package significantly outperformed their peers in the traditional group. The improvement was so large that it suggested the method itself was the deciding factor in their success. The researchers found that the structured way the software guided students through problems—balancing freedom to explore with clear support—helped them grasp complex ideas much better than listening to a lecture did.

The study also examined whether the students' backgrounds or gender affected these results. The data showed that gender did not matter; boys and girls benefited from the technology package equally, and neither group outperformed the other. This is a crucial finding, as it suggests that this type of learning tool does not widen the gap between male and female students but rather provides an equal opportunity for both. Socioeconomic background, however, played a more complex role. Students from wealthier families reported slightly more positive feelings about science after the intervention, a trend that often reflects their broader access to resources and support at home. Yet, surprisingly, their family wealth did not change how well they performed on the tests. Both wealthy and less wealthy students achieved similar high scores when they used the technology package. This indicates that while a student's background might influence how they feel about science, the right kind of teaching tool can help them all succeed academically, regardless of their economic status.

These findings offer a clear path forward for science education in resource-constrained settings. The study demonstrates that you do not need high-speed internet to bring the benefits of interactive, student-centered learning to a classroom. By using offline digital tools that are carefully designed to guide students through inquiry, teachers can help students not only learn facts but also develop a genuine love for discovery. The research suggests that the key to success lies not just in the technology itself, but in how it is used. The software worked because it provided a structured environment where students could explore safely, make mistakes, and receive instant help, a balance that traditional lectures often fail to provide. For schools with limited budgets, this approach offers a scalable way to improve education without waiting for infrastructure to catch up.

Ultimately, the study confirms that effective science education is possible even in challenging environments, provided the methods are adapted to the reality on the ground. The success of the TIBLEP package shows that when students are treated as active investigators rather than passive listeners, they rise to the occasion. They learn more, they feel better about what they are learning, and they do so without the need for expensive or unreliable connections. This approach does not just raise test scores; it builds a foundation for a more equitable future where every student, regardless of their background or gender, has the chance to engage deeply with the world of science.
