A CONTENT ANALYSİS OF HEART AND LUNG FİGURES İN SCİENCE AND TECHNOLOGY TEXTBOOKS AT THE ELEMENTARY LEVEL

This study was carried out to investigate the incorrect knowledge about the heart and lung figures in Science and Technology textbooks. With the evaluation of the textbooks from 4 to 8 grades using document analysis, it is understood that they do not show the heart under the left side of dorso-ventral plane at four and six grades. There is not a parallelism with the volume and number of left and right sides’ lobes on the pictures. The incorrect content of heart and lung figures may have negative effects on the subsequent learning.
