Drawing upon constructivist and social constructivist theories, the study examined how this programmes enhance critical thinking, research abilities, academic performance and information seeking behaviour. Utilising a mixed methods approach, pre-and-post-programme assessment scores, academic performance metrics, and qualitative insights were collected and analysed. The data revealed significant improvements in critical thinking and the research abilities, with participants experiencing an average increase of 35.0 percentage points. Academic performance metrics demonstrated higher grades and reduced course withdrawals among programme participants. Additionally, a shift in information-seeking behaviour was observed, reflecting a more sophisticated approach to accessing and evaluating information. The findings underscore the essential role of information literacy education in cultivating well rounded learners equipped to thrive in the information age. Recommendations were made for educators, administrators, and the policy makers, emphasising the need for continued research and investments in information literacy programmes.
