Student-centered learning was the pedagogical approach that was tried but found wanting in Charles Martell's classroom; the experience which he describes in his 1972 "JELIS" article. Persuaded by research accounts that student-centered teaching was more effective in stimulating critical thinking, he sought to apply it to enhance graduate education in library and information science (LIS). In this commentary, the author shares her views on Martell's idea of student-centered learning and how student-centered learning has evolved since 1972.
