<![CDATA[The ability to write personal emails and foster creative attitudes in Indonesian language learning among primary school students remains suboptimal. Students often struggle with idea development, structuring emails appropriately, and conveying messages using effective language. Additionally, the predominance of teacher-centered instruction limits student participation and hinders creative potential. This study aims to: (1) describe the implementation of the Project-Based Learning (PjBL) model assisted by flipbooks in teaching personal email writing; (2) analyze the effectiveness of flipbook-based PjBL in enhancing sixth-grade students’ creative attitudes; and (3) examine its effectiveness in improving personal email writing skills. A mixed methods approach was employed, involving 30 sixth-grade students at SD Negeri Mangkang Wetan 02, Semarang. Data were collected through observation, interviews, documentation, and written tests (pretest–posttest), and analyzed using N-Gain testing and qualitative descriptive analysis. The results show that the use of flipbook-based PjBL effectively improved students’ creative attitudes—specifically in fluency, flexibility, originality, and elaboration of ideas—with most students performing in the good to excellent categories. The average writing skill score increased from 64.56 to 95.06, with an N-Gain of 0.86 (high category). The study concludes that flipbook-assisted PjBL significantly enhances students’ creativity and writing proficiency. The findings highlight the potential of flipbooks as innovative instructional media that promote learner autonomy and active student engagement in the learning process.]]>
