To follow up on these problems, the researchers tried to provide a solution to the problem, namely by using a combination of learning models consisting of Problem Based Learning (PBL), Children Learning In Science (CLIS). The approach used in this research is qualitative research and this type of research applies classroom action research. The types of data presented in this study are qualitative data and quantitative data. Qualitative data in the form of data on teacher activities, student activities and student learning motivation in teaching and learning process activities, through observation with observation sheets.

After conducting 4 meetings with 2 cycles, the results showed that the activities of teachers, students, student learning motivation, WASAKA character and learning outcomes increased in each cycle with the categories "Very Active", "Very High" and "Completed".
