Direct linkHoe, Kai Yee; Subramaniam, R. – Chemistry Education Research and Practice, 2016
This study presents an analysis of alternative conceptions (ACs) on acid--base chemistry harbored by grade 9 students in Singapore. The ACs were obtained by the development and validation of a 4-tier diagnostic instrument. It is among the very few studies in the science education literature that have focused on examining results based also on…

Tang, Kok-Sing – Teaching Science, 2015
This article presents an instructional strategy called Premise-Reasoning-Outcome (PRO) designed to support students in the construction of scientific explanations. Informed by the philosophy of science and linguistic studies of science, the PRO strategy involves identifying three components of a scientific explanation: (i) premise--an accepted…

Oh, Elisabeth Yian Yian; Treagust, David F.; Koh, Thiam Seng; Phang, Wei Lian; Ng, Shuh Lit; Sim, Gary; Chandrasegaran, A. L. – Teaching Science, 2012
An instructional program using four simulation applets was used to facilitate understanding of gas and liquid pressure concepts among twenty-two students in a Year 9 class from an independent secondary school in Singapore. A comparison group consisting of twenty-two students was taught using traditional didactic, chalk-and-talk instruction.…

Othman, Jazilah; Treagust, David F.; Chandrasegaran, A. L. – International Journal of Science Education, 2008
A thorough understanding of chemical bonding requires familiarity with the particulate nature of matter. In this study, a two-tier multiple-choice diagnostic instrument consisting of ten items (five items involving each of the two concepts) was developed to assess students' understanding of the particulate nature of matter and chemical bonding so…
