On the naive concept about “Electricity" and its concept transformation，the following two things became clear. 1) Pupils before learning“Function of Electricity" had three naive concepts about “Electricity". 2) The learning activity of “Function of Electricity" was effective in letting transform the pupils' naive concept “that the electricity is passed to from the both + pole and the - pole" to the scientific concept “that electricity flows through the - pole from the + pole". And the effect was able to maintain it for at least three months. In addition，the following two matters were confirmed. 1) As for the scientific concept，it was admitted that it passed after learning in one year reversion to the naive concept again. 2) The naive concept in itself did not transform to the scientific concept when pupils did not experience learning.
