This experimental research aims at discovering the effect of problem based learning and authentic assessment on natural science learning outcome by controlling achievement motivation. This research was done on eighth grade students in Manggis Sub district with 2x2 factorial design. The data of learning result were collected by test and achievement motivation data were collected by questionnaire. The obtained data were analyzed by using two ways Analisis of Covariance. The result of this research discovers that by controlling achievement motivation, both problem based learning and authentic assessment have positif effect on students' learning outcome. In addition, there is an interactional effect of instructional model and assessment type on students' natural science learning outcome. Problem based learning is more appropriate to authentic assessment; meanwhile conventional model is more appropriate to conventional assessment. Based on those findings, it is recommended to implement problem based learning by considering the assessment typed used.
