The problem of this research is that low mathematics learning outcomes are caused by students' low creative thinking abilities. This research aims to determine the increase in students' creative thinking abilities regarding data presentation at SDN Sukajaya through a problem based learning model, with a class V sample. The method used in this research is a quantitative experimental method with the type of Pre-Experimental Designs. The data collection technique uses observation, tests and documentation. The data analysis technique uses N-Gain. Based on the data analysis, the conclusion is obtained: there is an increase in the creative thinking abilities of fifth grade students at Sukajaya State Elementary School after using the problem based learning model in data presentation material, because seen from the results of the N-Gain test the value shows a value of 0.8, which is included in the high criteria.

Since the national curriculum was changed to text-based, explanatory texts have become one of the types of texts that are taught to students in class X of high school.

However, there are still several problems in the achievement of these competencies. Based on the problems encountered in the field, it is known that innovative and creative explanatory text writing learning media is still lacking. An explanatory text is a text that provides information about a process resulting from the phenomenon of tang occurring. PBL (Problem based Learning) is a method of student-centered learning in this model is to improve students' ability to solve problems, use thinking skills and develop life skills such as critical thinking and teamwork. This mix method was chosen because it has suitability because in this study what is to be answered includes outcomes and the process of developing qualitative and quantitative data because in this method it is more about asking how the needs of high school class X students for the PBL model with learning media to produce explanatory texts based on digital media and local wisdom in order to facilitate and understand the mistakes of the research. In this case, it can also improve students' ability to solve problems, use various thinking skills and develop life skills.
