Level of Acceptability of Human Circulatory System Model for Non-Biology Major and Biology Major Teachers

This study aimed to develop and determine the acceptability of a Human Circulatory System Model for Grade 9 Biology education in Sorsogon Province, Philippines. The model was designed to address misconceptions and enhance understanding of the circulatory and respiratory systems’ interrelationship. The study employed a Descriptive Developmental Research Design and purposively selected Science teachers, both Biology and Non-Biology majors, as validators. The model’s acceptability was evaluated along four factors: Concept Quality, Instructional Quality, Technical Quality, and Accuracy. Results showed that both groups of teachers rated the model as Very Satisfactory across all factors, indicating its high acceptability and potential effectiveness in teaching. The study found no significant difference in the acceptability ratings between the two groups of teachers. The researchers concluded that the unidirectional mechanism of the model could effectively simulate blood circulation and oxygenation processes. They recommended further enhancements to the model and its adoption in other schools and grade levels to improve students’ understanding of human body mechanisms.
