Abstract: This research aims to identify whether or not and to what extent animation video
can improve students' vocabulary mastery. This is a Classroom Action Research conducted at
the sixth grade students of MIN Nglungge, Polanharjo. There were 2 cycles and each cycle
consists of five steps, namely; (1) planning the action, (2) implementing the action, (3)
observing the action, (4) reflecting the result of the observation, (5) revising of the action.
The result of the research shows that animation video can improve the students' vocabulary
mastery. It could be seen from these indicators: (a) students could spell the vocabularies; (b)
most students were able to pronounce words correctly; (c) students could grasp the meaning
well; and (d) students could recognize vocabularies. In line with the result, the writer
suggests that animation video is one of the effective techniques in presentations as to increase
the students' enthusiasm and their achievement in learning vocabulary. This result hopefully
