research is students of class V
B
. There are 20 student in the class, consisting 13
female and 7 male, they were heterogeneous in academic ability. The goal of this
study is to improve students’ mathematics achievement, especially in Basic
Competencies in Writing the symbol of time using 12 and 24 hours notation,
Arithmetic operations of time unit, and Measuring an angle by applying the
Cooperative Learning STAD. This study is an action research. There are two
cycles and four stages in this study. Each cycle has four stages, they are planning,
action, observation, and reflection. The result of research showed that the
improvement of students learning achievement. The percentage of first cycle
showed that students who get minimum achievement criteria, from 75% to 80%.
While, in the second cycle, the percentage of students who minimum achievement
criteria increase to 90%. In other words, the implementation of Cooperative
Learning STAD can improve students’ mathematics achievement in class V
B
of
SDN 019 Muara Uwai, especially in Basic Competencies in Writing the symbol
of time signal using 12 and 24 hours notation, Arithmetic operations of time unit,
and Measuring an angle.
