This study aims to develop a Project-Based Learning (PjBL)-based textbook on communication tools and civilization, evaluate its quality, and examine its effectiveness in strengthening the integrity character of fourth-grade elementary school students.
This study employed a Research and Development (R&D) approach using the ADDIE model, consisting of Analyze, Design, Develop, Implement, and Evaluate stages. The effectiveness of the developed textbook was examined through a quasi-experimental design involving 54 fourth-grade students, with 27 students assigned to the experimental group and 27 to the control group at an elementary school in Yogyakarta. The experimental group participated in five creative projects related to the civilization of communication tools, while the control group received conventional instruction. Data were analyzed using descriptive statistics, expert validation, ANCOVA, and N-Gain analysis.
The needs analysis showed that existing learning practices for fostering integrity were generally low, with a mean score of 1.98. Expert validation of the developed textbook achieved a mean score of 3.81, categorized as very good and requiring no revision. ANCOVA results demonstrated a significant effect of the textbook implementation on students’ integrity character, F(1, 51) = 90.997, p = 0.001, η²p = 0.645. The experimental group also achieved an N-Gain score of 0.6692, indicating a moderate-to-high improvement, whereas the control group showed no significant change.
The PjBL-based textbook on communication tools and civilization, developed using a genetic approach, is effective in strengthening the integrity character of elementary school students. Future studies are recommended to involve larger samples and examine potential mediating factors, including parenting styles and students’ exposure to social media.
