Abstract

This research was motivated by the low ability of children to master spatial geometry concepts in class B2 of PAUD IT Nurwahdah Cendekia. This issue was caused by the dominance of conventional two-dimensional learning, which failed to adequately facilitate children's tactile interaction. This Classroom Action Research (CAR) aimed to improve early childhood spatial geometry conceptual understanding (cubes, blocks, and triangular pyramids) through a learning method based on the project construction of geometric shape nets. The study was conducted in two cycles involving 13 students. Data were collected through initial assessments, process observations, and performance appraisals of object construction using recycled cardboard nets. The results indicated a significant increase in classical completeness. In the pre-cycle condition, child completeness only reached 46.2% (6 children). Following the implementation of project-based learning in Cycle 1, completeness increased to 53.8% (7 children), which was not yet optimal due to fine motor constraints and group sectoral ego. After tactical improvements were made in Cycle 2, the classical completeness rate surged sharply to 84.61% (11 children), successfully exceeding the predetermined success indicator of 75%. Learning through direct construction activities using recycled cardboard net media is proven effective in enhancing visual-spatial intelligence, kinesthetic independence, and mathematical connection skills in early childhood.
