Al-Balushi, Sulaiman M. – EURASIA Journal of Mathematics, Science & Technology Education, 2013
The effect of different textual versions (macroscopic (control), submicroscopic, and guided imagery) of the explanation of a chemical phenomenon on students' submicroscopic explanation of a related phenomenon was examined. The sample included 152 pre-service science teachers. The three textual versions of the explanation were distributed randomly…

Factors Influencing Pre-Service Science Teachers' Imagination at the Microscopic Level in Chemistry
Peer reviewed Peer reviewed
Direct linkDirect link
Al-Balushi, Sulaiman M. – International Journal of Science and Mathematics Education, 2009
This study explores the mental images at the microscopic level of matter created by 22 preservice science teachers in Oman. Participants were encouraged during a guided imagery session to construct mental images for a scenario written about the explanation of the reaction of sodium in water. They were then asked to describe what they envisioned in…
