EFEKTIVITAS MODEL PEMBELAJARAN KOOPERATIF TIPE JIGSAW DALAM MENUMBUHKAN KETERAMPILAN KOMUNIKASI LISAN DAN HASIL BELAJAR KOGNITIF PESERTA DIDIK

Abstract

This study aims to determine the effectiveness of Jigsaw cooperative learning model in developing communication skills and cognitive learning outcomes of students. This type of research is a quasi-experimental research using the one group pretest-posttest design. The population in the study were all students of class X MIA SMA Al-Kautsar Bandar Lampung for the 2018/2019 academic year. The sample of this research is the students of class X MIA 1 who were selected through purposive sampling technique. Data on oral communication skills were carried out by self-assessment, peer assessment and observation which were analyzed using a Likert scale. Meanwhile, data on cognitive learning outcomes were obtained through pretest and posttest scores, then analyzed by performing the n-gain score test. The research data shows that students have oral communication skills in the "high" category, which is as much as 77%. The highest verbal communication skills of students are found in the indicator of delivering detailed information with the "very high" category, while the lowest communication skills are found in the indicator of giving questions in the "enough" category. Then for learning outcomes, statistically student learning outcomes showed a significant difference between initial understanding (pretest) and understanding after learning (posttest) indicated by a significant N-gain value of 0.73 with high criteria. Thus, it can be concluded that the Jigsaw cooperative learning model is effective in developing communication skills and cognitive learning outcomes of students. Educators can apply the jigsaw type of cooperative learning model to similar materials or topics in developing oral communication skills and cognitive learning outcomes of students.
