IMPLEMANTATION OF E-LKPD IN THE DALIHAN MODEL TO IMPROVE STUDENTS’ LEARNING OUTCOMES AND CREATIVE THINKING SKILLS ON BIODIVERSITY MATERIAL AT CLASS X SMA NEGERI 1 SIANTAR

This study aims to determine the improvement in students’ learning outcomes and creative thinking skills through the implementation of E-LKPD in the DALIHAN model on biodiversity material at Class X of SMA Negeri 1 Siantar. The study uses a quantitative approach with an experimental method and a pretest-posttest control group design. The research sample consisted of Class X-2 as the experimental class, which used E-LKPD in the DALIHAN model, and Class X-10 as the control class, which followed learning through lectures and question-and-answer sessions. Data were collected through tests administered before and after learning and were analyzed using SPSS 21. The average score of the experimental class increased from 67.93 on the pretest to 88.73 on the posttest, while the control class increased from 52.17 to 65.94. The normality test showed that the data were normally distributed, and the homogeneity test obtained a significance value of 0.487. The Independent Samples t-test showed a significance value of 0.000, indicating a significant difference between the groups. The results support the implementation of E-LKPD in the DALIHAN model as an alternative learning approach to support students’ learning outcomes and creative thinking skills.
