The main purposes of this study are 1) to examine whether preservice elementary and lower-secondary school teachers have familiarity with using photographs and pictures of 25 biological implements using their photographs and pictures in elementary and lower- secondary school science textbooks, and 2) to investigate whether they know the names of the implements shown in the textbooks. The main findings of this study were as follows ; 1) less than 70% of the teachers had seen four out of 25 kinds of the implements ; 2) less than 70% of the teachers had used seven out of 25 kinds of the implements ; and 3) none of the teachers correctly wrote the names of the all kinds of implements. The authors suggested some teaching strategies to improve the problems mentioned above.
