Chua, Jia Xun; Tan, Aik-Ling; Ramnarain, Umesh – Research in Science & Technological Education, 2019
Background: Nature of Science (NOS) is defined to be the epistemology of science, and comprised of distinctive defining aspects. The representation of these NOS aspects in school science textbooks is likely to affect how students understand NOS. Representation of NOS aspects can differ between topics even within the same textbook and these topical…

Chin, Christine; Chia, Li-Gek – Science Teacher, 2008
One way of implementing project-based science (PBS) is to use problem-based learning (PBL), in which students formulate their own problems. These problems are often ill-structured, mirroring complex real-life problems where data are often messy and inclusive. In this article, the authors describe how they used PBL in a ninth-grade biology class in…
