摘要: The National Science Education Standards emphasise the use of concepts and skills that cut across science domains. One these cross‐cutting areas is measurement. Students should know measurement systems, units measurement, tools error in as well importance to scientific endeavours. Even though an essential skill, little known about how students estimate different contexts. This study examines impact teaching their bodies rough (body rulers) on ability linear measurements. Nineteen middle school participated metric intervention tasks completed a pre‐instruction post‐instruction Linear Measurement Assessment. Results showed body measures (a ruler) for estimation had significant influence accuracy. After instruction, were better able sizes o...
