Penerapan Model Project Based Learning untuk Meningkatkan Keterampilan Kolaborasi Murid Kelas VI SD pada Mata Pelajaran IPAS Materi Sistem Peredaran Darah Manusia

Abstract

Collaboration skill is one of the 21st century competencies that elementary school students need to master, including in Social and Natural Science (IPAS) learning. This study aimed to describe the implementation steps of the Project Based Learning (PjBL) model and to improve the collaboration skills of sixth-grade students on the topic of the Human Circulatory System. The novelty of this study lies in a three-cycle design in which project products become progressively more complex (an organ identification worksheet, a three-dimensional model, and a diorama) and in the cycle-by-cycle monitoring of each collaboration indicator. This study used a Classroom Action Research (CAR) design conducted in three cycles: cycle I focused on the organs of the circulatory system and their functions, cycle II focused on the mechanism of pulmonary and systemic circulation, and cycle III focused on circulatory disorders and ways to maintain circulatory health. The subjects were 28 sixth-grade students of SDN 066 Halimun divided into seven groups. Data on collaboration skills were collected through observation sheets covering five indicators: positive interdependence, face-to-face interaction, individual accountability, interpersonal communication skills, and group processing skills, then analyzed descriptively and quantitatively. The results showed an increase in the average percentage of collaboration skills from 70.54% in cycle I, to 80.36% in cycle II, and 87.50% in cycle III, exceeding the research success indicator of 85%. It can be concluded that the implementation of the Project Based Learning model is able to improve the collaboration skills of sixth-grade students in learning the Human Circulatory System because students are trained to design, create, and present projects collaboratively with clear roles and responsibilities. The findings offer teachers a replicable sequence of projects for strengthening the collaboration dimension of the graduate profile.
