A groundbreaking study by Thyolo Secondary School chemistry teacher, Arnold Valaro, has revealed that students perform significantly better when taught with projectors compared to traditional chalkboard methods. 

The research, titled "Empirical Analysis of PowerPoint Projector Use on Secondary School Performance in Physics and Chemistry in Malawi," analyzed examination scores from 247 students across five schools.

Valaro's study found a statistically significant improvement in student performance when projectors were used, highlighting the potential of technology to enhance teaching and learning.

The paper was first published in Indonesia this month.

"Policymakers and education authorities should focus on strategic allocation of resources, prioritizing teachers with strong subject-specific qualifications and competence," Valaro recommends.

He also emphasizes the importance of leveraging technology to enhance teaching and learning, suggesting that educators design content-specific materials and use projectors to explain complex concepts. 

"The study's findings have implications for education policy in Malawi, where investing in technology and teacher training could lead to improved academic outcomes," he said.

Similar studies have shown that multimedia instruction can significantly improve student performance, with one study indicating a notable increase in achievement scores.
