The Impact of Graphic Organizer in Constructivist Learning: A Systematic Review for Developing a Teaching Primer

Abstract

Despite the recognized importance of concept acquisition in elementary education, many learners continue to struggle with abstract concepts due to the persistent use of rote memorization and the limited integration of visual learning strategies. This gap highlights the need for more effective instructional tools to support meaningful and active learning.
This study aimed to evaluate the effectiveness of graphic organizers in enhancing conceptual understanding among elementary learners and to identify trends in their pedagogical application, particularly within the context of local and international educational settings relevant to the Philippine basic education system.
Following the PRISMA 2020 guidelines, a systematic review of 23 studies published between 2020 and 2025 was conducted. Data were collected from various academic databases and analyzed using thematic synthesis and “cool and warm” analysis to examine the impact of both print and digital graphic organizers. Results revealed that graphic organizers significantly improve student performance across core subjects such as Science, Mathematics, and Language. Specifically, 69.5% of the studies supported the effectiveness of print-based tools, while 30.4% highlighted the growing impact of digital graphic organizers. These tools were found to reduce cognitive load and enhance both individual understanding and collaborative learning.
The study concludes that graphic organizers are essential tools for promoting higher-order thinking skills in 21st-century classrooms. However, gaps in teacher training and access to digital resources remain. It is recommended that schools integrate graphic organizers into the MATATAG curriculum and utilize the proposed Teaching Primer to guide educators in effectively implementing visual-spatial strategies.
