This article discusses the creativity of teachers in making thematic science teaching materials. The purpose of this article is to know that teacher creativity can be developed through training so that teachers can create thematic science teaching materials. Creativity consists of three dimensions namely cognitive (creative thinking), affective (creative attitude) and psychomotor (creative skills). Creative thinking includes: fluency, flexibility, originality, elaboration and evaluation. Creative attitudes include openness, flexibility in attitude, freedom in self-expression, appreciating fantasy, interest in creative activities, belief in ideas themselves, self-reliance in giving consideration. While creative (psychomotor) skills include determining creative challenges, identifying sources of information, developing and selecting ideas, presenting product results, and authenticity. Related to the creativity of teachers, teachers are expected to make thematic materials of science. Science thematic teaching materials are all forms of materials used to assist teachers or instructors in carrying out teaching and learning activities in the classroom in the form of written or unwritten materials that focus on science learning to grow students' abilities in an incanity and conceptual way according to real life. The step of developing teacher creativity training can train teachers in making science thematic teaching materials that benefit teachers and appeal to students. This research aims to develop the creativity of teachers in creating science thematic teaching materials through training through the Microsoft PowerPoint app. The method of writing this scientific work is to use Research and Development (RnD).
