Abstract. The aim of study was to find out: (1) Student learning outcomes of problem based learning model with crossword puzzles were higher than direct instruction learning model. (2) Science learning outcomes of students who had high motivation were better than students who had low motivation. (3) There were interaction between learning models and learning motivation in influenced learning outcomes. This study usesd a quasi experimental method. The sample of consists of two classes, class Va amounts 28 students treated problem based learning model with crossword puzzles (experimental group) and class Vb amounts 27 students treated direct instruction learning model (control group). The instruments were multiple choice tests and learning motivation questionnaire. This study used factorial 2 x 2 design with 2 lane ANAVA technique. The results of this study indicate: (1) Science student learning outcomes treated problem based learning model with crossword puzzles were higher than students direct instruction learning model. Sig. 0.000 <0,05, (2) Science learning outcomes of students who had high motivation were better than students who had low motivation. Sg. 0,000 <0,05, (3) There were interaction between learning models and learning motivation in influenced learning outcomes shown. Sg. 0,000 <0,05
