PENGARUH MODEL ROLE PLAYING TERHADAP KETERAMPILAN BERBICARA SISWA PADA PEMBELAJARAN BAHASA INDONESIA KELAS lV SDN 064966 MEDAN PERJUANGAN

Abstract

Speaking skill is one of the core competencies that students at the elementary
school level need to develop, particularly in Indonesian Language Learning. This
research was conducted to examine the extent to which the Role Playing learning
model influences the speaking skills of fourth-grade students at SDN 064966 Medan
Perjuangan. A quasi-experimental design was applied with a non-equivalent control
group design. The study population comprised 48 fourth-grade students, all of whom
were included as research samples through total sampling technique. Class IV-A
consisting of 28 students was treated as the experimental class and received
instruction using the Role Playing model, while Class IV-B with 20 students served
as the control class and underwent conventional teaching. The research instrument
was a performance test assessed using a speaking skills rubric with six evaluated
aspects: dialogue delivery in drama, dialogue intonation, pronunciation, facial
expression (mimicry), role characterization, and improvisation in drama. The rubric
underwent expert validation prior to use. Data collection was carried out through
pretest and posttest procedures. Statistical analyses included the Shapiro-Wilk
normality test, Fisher homogeneity test, and Independent Sample t-Test for
hypothesis testing. Findings revealed that the experimental class achieved a higher
average posttest score (72.97) compared to the control class (61.67). The t-test
result showed t-count 2.359 > t-table 2.013, indicating a significant influence of the
Role Playing model on students' speaking ability. It is concluded that Role Playing
is an effective instructional strategy for enhancing speaking skills in Indonesian
Language Learning while simultaneously nurturing students' self-confidence,
creativity, and communication competence.
