Pengembangan E-LKPD Berbasis PBL untuk Melatihkan Keterampilan Berpikir Kreatif Peserta Didik Kelas XI pada Materi Asam Basa

Development of Electronic Worksheets (E-LKPD) Based on PBL Model to Train Creative Thinking Skills of Class XI Students on Acid-Base Material

Keterampilan berpikir kreatif penting untuk dilatihkan pada peserta didik dalam menghadapi tantangan abad 21 dan termasuk keterampilan berpikir tingkat tinggi. Salah satu upaya untuk melatihkan keterampilan berpikir kreatif  adalah dengan menggunakan media pembelajaran relevan, yakni E-LKPD berbasis model Problem Based Learning (PBL). Tujuan penelitian ini menghasilkan E-LKPD berbasis PBL untuk melatihkan keterampilan berpikir kreatif peserta didik kelas XI pada materi asam basa yang layak digunakan, ditinjau dari aspek validitas, kepraktisan, dan keefektifan.  Model penelitian ini berpedoman pada model 4D Thiagarajan (Define, Design, Develop, dan Disseminate). Namun penelitian hanya sampai tahap pengembangan (Develop) dengan uji coba terbatas kepada 20 peserta didik SMAN 1 Menganti, Gresik pada 22 Februari 2024. Hasil penelitian menunjukkan bahwa validitas E-LKPD dinyatakan valid ditinjau dari skor median validitas isi sebesar 4 dengan kategori valid dan validitas konstruk sebesar 5 dengan kategori sangat valid. Kepraktisan E-LKPD dinyatakan praktis ditinjau dari hasil angket respon peserta didik sebesar  97,33% dengan kategori sangat praktis dan didukung dengan hasil persentase observasi aktivitas peserta didik sebesar 98,61% aktivitas peserta didik relevan. Keefektifan E-LKPD ditinjau dari hasil posttest keterampilan berpikir kreatif pada aspek kelancaran sebesar sebesar 93,75%, aspek keluwesan sebesar 92,92%, aspek orisinalitas sebesar 84,17%,  dan aspek elaborasi sebesar 80% dengan kategori kreatif hingga sangat kreatif,  serta skor n-gain dari pretest dan posttest keterampilan berpikir kreatif, serta pengetahuan didapatkan skor >3 dengan kategori sedang dan tinggi. Berdasarkan hal tersebut, E-LKPD berbasis PBL layak untuk melatihkan keterampilan berpikir kreatif peserta didik kelas XI pada materi asam basa.

Creative thinking skills are important to train students in facing the challenges of the 21st century and include higher order thinking skills. One of the way to train creative thinking skills is by using relevant learning media, namely Electronic Worksheet (E-LKPD) based on the Problem Based Learning (PBL) model. The purpose of this research is to produce Electronic Worksheet (E-LKPD) based on PBL model to train the creative thinking skills of grade XI students on acid-base material that is feasible to use, in terms of validity, practicality, and effectiveness.  This research model is guided by the Thiagarajan 4D model (Define, Design, Develop, and Disseminate). However, the research only reached the development stage (Develop) with a limited trial to 20 students of SMAN 1 Menganti, Gresik at February 22, 2024. The results showed that the validity of Electronic Worksheet (E-LKPD) was declared valid in terms of the median score of content validity of 4 with a valid category and construct validity of 5 with a very valid category. The practicality of Electronic Worksheet (E-LKPD) is declared practical in terms of the results of the student response questionnaire of 97.33% with a very practical category and is supported by the results of the percentage of student activity observations of 98.61% of relevant student activities. The effectiveness of Electronic Worksheet (E-LKPD)  is reviewed from the results of the creative thinking skills posttest on the fluency aspect of 93.75%, the flexibility aspect of 92.92%, the originality aspect of 84.17%, and the elaboration aspect of 80% with creative to very creative categories, as well as the n-gain score from the pretest and posttest of creative thinking skills, and knowledge obtained a score of > 3 with moderate and high categories. Based on this, Electronic Worksheet (E-LKPD) based on PBL model is feasible to train the creative thinking skills of grade XI students on acid-base material.
