Pengembangan e-LKPD Inkuiri-Flipped Classroom pada Materi Kesetimbangan Kimia untuk Melatih Keterampilan Berpikir Kritis Berdasar Kurikulum Merdeka

Development of Inquiry-Flipped Classroom e-LKPD on Chemical Equilibrium Material to Train Critical Thinking Skills Based on the Merdeka Curriculum

Penelitian ini bertujuan untuk memperoleh e-LKPD yang layak untuk melatihkan keterampilan berpikir kritis peserta didik. Jenis penelitian ini termasuk penelitian dan pengembangan. Model pengembangan yang digunakan mengacu pada model 4-D namun hanya dibatasi pada tahap define, design, dan develop. Kegiatan uji coba dilaksanakan pada satu kelas yang dipilih secara acak. Kelayakan e-LKPD yang dikembangkan berpedoman pada validitas, kepraktisan, dan keefektifan. Validasi dilakukan oleh validator ahli dengan skor ditentukan berdasarkan nilai modus. Hasil validasi diperoleh skor 5 dengan kategori sangat valid pada ketiga e-LKPD. Hasil analisis kepraktisan dilihat dari hasil angket respon peserta didik dan observasi aktivitas peserta didik. Persentase kepraktisan berdasarkan angket respon peserta didik diperoleh sebesar 98,08% dengat kategori sangat praktis. Sedangkan untuk hasil observasi aktivitas peserta didik diperoleh aktivitas relevan pada pertemuan 1 sebesar 94,23%, pertemuan 2 sebesar 93,34%, dan pertemuan 3 sebesar 93,78%. Dari ketiga persentase aktivitas tersebut diperoleh persentase aktivitas relevan peserta didik sebesar 93,78% sehingga dapat dikatakan e-LKPD yang dikembangkan sangat praktis. Hasil analisis keefektifan e-LKPD diukur berdasarkan nilai skor hasil belajar kognitif yang dianalisis menggunakan uji Wilcoxon dan uji ketuntasan klasikal serta nilai hasil keterampilan berpikir kritis yang dianalisis menggunakan uji t dan uji ketuntasan klasikal. Hasil uji Wilcoxon pada nilai hasil belajar kognitif diperoleh nilai signifikansi sebesar 0,000 dan persentase uji ketuntasan klasikal sebesar 93,75%. Hasil nilai keterampilan berpikir kritis dari uji t didapatkan nilai signifikansi sebesar 0,000 dan persentase uji ketuntasan klasikal sebesar 96,88%. Dari kedua hasil analisis tersebut e-LKPD yang dikembangkan dapat dikatakan efektif. Berdasarkan hasil analisis validitas, kepraktisan, dan keefektifan diperoleh bahwa e-LKPD inkuiri-flipped classroom untuk melatih keterampilan berpikir kritis yang dikembangkan layak untuk digunakan.

This study aims to obtain a feasible e-LKPD to train students' critical thinking skills. This type of research includes research and development. The development model used refers to the 4-D model but is only limited to the define, design, and develop stages. The pilot test was conducted in one randomly selected class. The feasibility of the developed e-LKPD is guided by validity, practicality, and effectiveness. Validation was conducted by expert validators with scores determined based on mode values. The validation results obtained a score of 5 with a very valid category on the three e-LKPDs. Practicality analysis results are seen from the results of the learner response questionnaire and learner activity observations. The percentage of practicality based on the students' response questionnaire was obtained at 98.08% with a very practical category. As for the results of the observation of students' activities, relevant activities were obtained at meeting 1 of 94.23%, meeting 2 of 93.34%, and meeting 3 of 93.78%. Of the three activity percentages, the percentage of relevant activities of students is 93.78% so that it can be said that the e-LKPD developed is very practical. The results of the e-LKPD effectiveness analysis were measured based on the score value of cognitive learning outcomes analyzed using the Wilcoxon test and classical completeness test and the value of critical thinking skills results analyzed using the t test and classical completeness test. The Wilcoxon test results on cognitive learning outcome scores obtained a significance value of 0.000 and a percentage of classical completeness test of 93.75%. The result of critical thinking skills value from t-test obtained a significance value of 0.000 and the percentage of classical completeness test was 96.88%. From both analysis results, the developed e-LKPD can be said to be effective. Based on the results of the analysis of validity, practicality, and effectiveness, it is found that the inquiry-flipped classroom e-LKPD to train critical thinking skills developed is suitable for use.
