Enhancing Students Mathematical Conceptual Understanding by Applying Guided Discovery Learning and Direct Learning Model

The purpose of this study is to analyze whether
there is an enhancement difference of mathematic conceptual
understanding ability (MCUA) of student which is taught by
guided discovery learning (GDL) and which is taught by direct
learning (DL). This study is quasi experimental study. The
population of this study is the eighth grade students of Madrasah
Tsanawiyah Negeri Barus. The sample of this study is taken
randomly, which consisted of two classes. The experiment class is
taught by guided discovery learning (GDL) and the control class
is taught by direct learning (DL). The result of study showed that
there is enhancement difference of mathematic conceptual
understanding ability (MCUA) of student which is taught by
guided discovery learning (GDL) and student which is taught by
direct learning (DL). The N – gained of mathematical concept
understanding ability of student which is taught by guided
discovery learning (GDL) is higher than student which is taught
by direct learning (DL).
