Effectivity of Guided Discovery Learning with Concept Mapping to improve conceptual understanding in endocrine system material for grade XI science class

Abstract

Abstract This research aims to examine the effectivity of Guided Discovery Learning with Concept Mapping of endocrine system material. It is a quasi-experimental study with cluster sampling design. The hypothetical population is all students of SMA Negeri 2 Ngaglik, Sleman. The research sample is 67 students of grade XI science class which is divided into two groups; 33 students as the experimental group (Guided Discovery Learning with Concept Mapping) and 34 students as the control group (using 5M strategy). The data for students’ conceptual understanding on endocrine system material was collected using multiple choice test. The result shows that the Guided Discovery Learning with Concept Mapping improves conceptual understanding of student with higher average score (83.03) than control class (72.59) on endocrine system material especially for grade XI Science with sig. 0.000 (sig.<0.005). The data analysis showed that Guided Discovery Learning with Concept Mapping is effective to improve students’ conceptual understanding on endocrine system material.
