This research aims to determine the process of using the Contextual Teaching and Learning Model in Improving Students'
Critical Thinking Abilities in Class IV Mathematics Subjects at SDN 1 Mamben Lauk. This type of research is Classroom
Action Research (PTK). The subjects in this research were all fourth grade students at SDN 1 Mamben Lauk consisting of 19
students, 11 boys and 8 girls. And the object is the Contextual Teaching and Learning Learning Model and Critical Thinking
Ability. This research was carried out in 2 cycles, the cycle consisting of 6 meetings. The data analysis technique is descriptive
analysis with percentages. Based on the research results using the Contextual Teaching and Learning Learning Model in two
cycles experienced a significant increase, where the first cycle obtained a classical percentage of 68% with fairly good criteria
and the second cycle obtained percentage data. classical 78.95% with good criteria. And the difference in improvement that
occurred from cycle I to cycle II reached 10.95%. Meanwhile, the results of the critical thinking ability test obtained from data
before corrective action was taken, the average classical score of students only reached 26.32 and the classical percentage
was 0%. After carrying out learning improvement actions in cycle I, the students' average score increased to 62.78 and the
classical percentage was 42.11%, with the number of 8 students entering the sufficient criteria. Then in the second cycle the
average student score increased again to 77.37 and the classical percentage was 78.95% with 15 students entering the good
criteria. And the difference in the average score from cycle I to cycle II reached 14.59, while the difference in the classical
percentage of students' critical thinking abilities from cycle I to cycle II reached 36.84%.
