PENGEMBANGAN LKPD BERBASIS COMPUTATIONAL THINKING BERMUATAN ETNOPEDAGOGI WISATA SURABAYA UNTUK MENINGKATKAN PEMAHAMAN KONSEPTUAL MATERI PELUANG PESERTA DIDIK KELAS VI SD

THE DEVELOPMENT OF COMPUTATIONAL THINKING-BASED STUDENT WORKSHEETS INTEGRATED WITH SURABAYA TOURISM ETHNOPEDAGOGY TO IMPROVE SIXTH-GRADE STUDENTS’ CONCEPTUAL UNDERSTANDING OF PROBABILITY

Penelitian ini bertujuan untuk mengembangkan LKPD berbasis Computational Thinking bermuatan etnopedagogi wisata Surabaya untuk meningkatkan pemahaman konseptual peserta didik pada materi peluang di kelas VI SD. Menggunakan metode Research and Development (R&D) model ADDIE dengan subjek penelitian berjumlah 28 peserta didik kelas VI-F SDN Pacarkeling V/186 Surabaya. Instrumen meliputi lembar validasi, angket kepraktisan, serta pretest dan posttest. Data dianalisis secara deskriptif untuk mengetahui tingkat validitas dan kepraktisan produk, sedangkan keefektifan produk dianalisis menggunakan N-Gain, paired sample t-test, dan effect size (Cohen’s d). Hasil penelitian menunjukkan validitas materi mencapai 80% (valid), validitas media terhadap LKPD sebesar 81,25% (sangat valid), dan validitas media terhadap kartu kwartet wisata sebesar 80% (valid). Tingkat kepraktisan mencapai 100% (sangat praktis) berdasarkan penilaian guru dan 86,20% (sangat praktis) berdasarkan respons peserta didik. Hasil keefektifan menunjukkan nilai N-Gain sebesar 0,53 dengan kategori sedang, nilai signifikansi (Sig. 2-tailed) < 0,001 yang menunjukkan perbedaan signifikan antara hasil pretest dan posttest, serta nilai Cohen’s d sebesar 1,846 dengan kategori efek besar. Dengan demikian, LKPD berbasis Computational Thinking bermuatan etnopedagogi wisata Surabaya dinyatakan valid, praktis, dan efektif digunakan untuk meningkatkan pemahaman konseptual peserta didik pada materi peluang.

This study aims to develop a Computational Thinking-based Student Worksheet (LKPD) integrated with Surabaya tourism ethnopedagogy to improve students’ conceptual understanding of probability material in sixth grade elementary school. This study employed the Research and Development (R&D) method used ADDIE model with subjects consisted of 28 students from class VI-F at SDN Pacarkeling V/186 Surabaya. The instruments included validation sheets, practicality questionnaires, as well as pretest and posttest assessments. Data were analyzed descriptively to determine the validity and practicality levels of the product, while product effectiveness was analyzed using N-Gain, paired sample t-test, and effect size (Cohen’s d). The results showed that the material validity reached 80% (valid category), media validity of the LKPD reached 81.25% (very valid category), and media validity of the tourism quartet cards reached 80% (valid category). The practicality level reached 100% (very practical category) based on teacher assessment and 86.20% (very practical category) based on students’ responses. The effectiveness results showed an N-Gain score of 0.53 in the moderate category, a paired sample t-test significance value (Sig. 2-tailed) of <0.001 indicating a significant difference between pretest and posttest results, and an effect size result with Cohen’s d value of 1.846 in the large effect category. Therefore, the Computational Thinking-based LKPD integrated with Surabaya tourism ethnopedagogy is considered valid, practical, and effective for improving students’ conceptual understanding of probability material in mathematics learning.
