This study aimed to determine the effectiveness of teaching using the inductive and deductive strategies on the improvement of learning achievement and motivation students. This study was a quasi-experimental study, involved all students of class IX of SMPN 2 Sentolo, Kulonprogo in the academic year of 2010/2011. Sample was established using the purposive sampling technique, two science classes each of 32 students were taught using the inductive and deductive strategy. The data were gathered  using a pretest and posttest. The students’ achievement was measured using a multiple choice test and their motivation were measured using a questionnaire and observation sheets. The results show that: (1) there is a difference of science instruction through deductive and inductive strategies on improving learning achievement, which is supported by Independent Samples Test in the t-test column for Equality of Means, score value of sig. (2 tailed) is 0,026; (2) there is no differences of deductive and inductive strategies on improving students’ motivation, which is supported by t-test column for Equality of Means, score value of sig. (2 tailed) is 0,153; (3) there is a significant correlation of motivation on learning science and science achievement, which is shown by the value of coefficient of correlation 0,736.
