One of the learning achievements obtained is Science subject for grade V. Learning science emphasizes logical thinking ability, not memorizing facts. Based on the preliminary observation, the researcher conducted a classroom action research on Science subject on the fifth grade students of SDN 2 Tribungan at Managran district in the first semester by using Jigsaw technique. Based on the results of the research, it can be concluded that: 1) The improvement of students’ learning achievement showed that learning motivation was influenced by the learning strategy given by the teacher.
