The Effect of Letter Card Media on the Recognition of Capital Letters in Indonesian Language Lesson for Second Grade Students at SDN 01 Balai Karangan

Difficulties in recognizing capital letters persist among second-grade students, hindering early literacy development. This study aims to determine the effect of letter-card media on students’ ability to recognize capital letters at SDN 01 Balai Karangan. The research employed a quantitative approach using a one-group pretest-posttest design. The study subjects were 24 second-grade students. Data were collected through oral tests administered before and after the implementation of the letter-card media. The data analysis techniques included the Chi-square normality test and the Wilcoxon non-parametric test, as the post-test data were not normally distributed. The results indicated a significant improvement in students’ ability to recognize capital letters, as shown by all positive score differences and the Wilcoxon test results (T⁺ = 325, T⁻ = 0, T = 0). These findings demonstrate that letter-card media is effective in improving capital letter recognition among second-grade students.
