Objective: This study aims to proving the effectiveness of quantum learning in increasing the achievement of internalization of Islamic values for kindergarten students. Bustanul Athfal Kindergarten is Aisyiyah's early childhood education institution. There, the organization of Islamic education, which aims to implant Islamic ideas in children from an early age so that they grow virtue-driven personalities, has become vital. It is expected that students have a very fundamental understanding (internalized) of their religious convictions and love for Islam from an early age.
Methods: The study used an experimental method with a two-group quasi-experimental design. The research subjects were 114 students from five kindergarten subjects, divided into the experiment of quantum learning model group and the control group (conventional model). To collect data, the researchers employed the authentic Islamic value assessment model as call MANIS. The data were then analyzed by t-test and N-Gain analysis.
Results and Conclusion: The t-test findings, first, demonstrated a substantial distinction between the quantum learning model and conventional model. According to the N-Gain results, the quantum learning model was more successful than conventional model model. Consistently, the quantum model outperformed the conventional group in terms of achievement and efficiency. So, the quantum learning model is efficient in increasing the achievement of students' internalization of Islamic values.
Recommendation: for the next teacher are to adopt the Quantum Learning Model in their learning process, especially in kindergarten, because this research shows that the model is effective in encouraging the achievement of internalization of Islamic values in children.
