We present and discuss the results of a survey on comprehension and of a simple experiment on the contents required in the teacher training education concerning the direct-current electric circuit in the science textbook for fourth graders in Japan. We demonstrate the effects introduced into the electric circuit by "the internal resistance of a dry cell battery" and "the non-linear resistivity of a miniature bulb" in the experiment, and discuss the educational contents and methods of elementary school teacher training.
