The document discusses misconceptions students have about cell structure and outlines methods used to correct those misconceptions. Students were asked to draw cells and describe their shape, size, and internal structures. Their initial responses showed misunderstandings, describing cells as 2D circles or rectangles. The teacher then led a class discussion using papers and food models to demonstrate cells are 3D objects. Students were asked to build 3D cell models, which helped shape their understanding of cells as complex 3D structures rather than simple shapes.
