Efektifitas Model Pembelajaran Brain Based Learning Berbantuan Media Teka-Teki Silang Terhadap Hasil Belajar IPAS Siswa Kelas IV SDN 128 Palembang

Abstract

Assisted by crossword puzzle media on the IPAS

learning outcomes of fourth-grade students at SDN

128 Palembang. The problem encountered was the

low student achievement due to teacher-centered

learning and the lack of innovative media. This

research employed a quantitative method using a true

experimental design in the form of a pretest-posttest

control group. The sample consisted of 68 fourth-

grade students, with Class IVA as the experimental

group and Class IVB as the control group. Data were

collected using short-answer tests in the form of

crossword puzzles and analyzed using SPSS version 22.

The results showed a significant improvement in

learning outcomes in the experimental class compared

to the control class. The average posttest score of the

experimental group was 92.06, higher than the control

group’s 79.92. The N-gain test showed an increase in

the moderate to high category, especially for indicator

C4 with a gain of 0.8275. Based on the hypothesis

testing, the significance value was < 0.025, thus Ha

was accepted. Therefore, the BBL model assisted by

crossword puzzle media is effective in improving IPAS

learning outcomes. Brain-based learning combined

with interactive media can create an engaging

learning atmosphere, encourage student activity, and

optimize cognitive potential.
