The student health workers first practice with the puzzle cards to learn the signs
of each problem. Then they use the big drawing of the man to review the different
problems and where on the body they appear.
The students take turns placing the colored nodes, wound, and lymph canal
pieces on the cardboard man to show the signs of problems described in Where
There Is No Doctor. They challenge each other to correctly identify and find the
treatment and prevention for each problem they create.
Test yourself. Can you name the probable causes of the swollen lymph nodes
shown in these photos?
By making these teaching materials themselves and testing each other with the
puzzle cards, health workers soon learn to recognize the different problems.
