This article takes up the argument from an earlier article and seeks to detail the importance and role of the history and philosophy of science (HPS), conceived as a unitary interdisciplinary field, in science education. However, on this count, it not only seeks to ground the salience for science education at the school level but also its role in higher education. While elaborating upon its importance in school education, it charts out additional areas where the HPS could enrich the already existing objectives envisaged. Furthermore, the article highlights the importance of HPS both at the level of the pedagogy of undergraduate education as well as research mentorship at the graduate level. While, for analytic purposes, these two spheres are addressed separately, the article argues for the need to forge linkages between them.
