PENGEMBANGAN E-LKPD MATERI JAMUR BERBASIS CONTEXTUAL TEACHING AND LEARNING UNTUK MELATIHKAN KEMAMPUAN BERPIKIR KRITIS PESERTA DIDIK KELAS X

DEVELOPMENT OF E-LKPD FUNGI MATERIAL BASED ON CONTEXTUAL TEACHING AND LEARNING TO TRAIN CRITICAL THINKING SKILLS OF GRADE X STUDENTS

Berpikir kritis perlu dilatihkan dalam pembelajaran biologi di sekolah agar peserta didik mampu menyelesaikan permasalahan di kehidupan sehari-hari dengan menganalisa data maupun informasi yang diperoleh. Tujuan dari penelitian ini adalah menghasilkan E-LKPD materi jamur berbasis Contextual Teaching and Learning yang berfokus dalam melatih peserta didik kelas X agar memiliki pola pikir yang kritis. E-LKPD dikembangkan menggunakan model pengembangan 4-D yaitu Define, Design, Develop, dan Disseminate dengan dua topik yaitu jamur makroskopis dan jamur mikroskopis yang diuji tingkat validitas, kepraktisan, dan keefektifannya. Validitas E-LKPD diperoleh dari lembar validasi yang dinilai oleh validator, kepraktisan diperoleh dari hasil angket respon dan lembar observasi keterlaksanaan peserta didik, dan keefektifan diperoleh dari hasil lembar tes evaluasi peserta didik. Uji validitas menunjukkan persentase rata-rata skor sebesar 97,41% (sangat valid). Uji kepraktisan menunjukkan persentase rata-rata skor berdasarkan hasil angket respon sebesar 95,93% (sangat praktis) dan hasil lembar observasi keterlaksanaan sebesar 93,99% (sangat praktis). Uji keefektifan menunjukkan rata-rata hasil nilai lembar tes evaluasi sebesar 88,15 dan persentase rata-rata ketercapaian indikator berpikir kritis sebesar 88% (sangat efektif). E-LKPD materi jamur layak digunakan dalam pembelajaran berlandaskan pada hasil uji kevalidan, kepraktisan, dan keefektifan. E-LKPD juga dapat dimanfaatkan menjadi bahan ajar alternatif pada materi jamur di sekolah untuk melatihkan kemampuan berpikir kritis peserta didik.

Critical thinking needs to be trained in biology learning at school so that students can solve problems in everyday life by analyzing data and information obtained. The purpose of this study is to produce E-LKPD mushroom material based on Contextual Teaching and Learning which focuses on training grade X students to have a critical mindset. E-LKPD was developed using a 4-D development model, namely Define, Design, Develop, and Disseminate with two topics, macroscopic fungi and microscopic fungi which were tested for validity, practicality, and effectiveness. The validity of E-LKPD is obtained from the validation sheet assessed by the validator, practicality is obtained from the results of response questionnaires and observation sheets of student implementation, and effectiveness is obtained from the results of student evaluation test sheets. The validity test showed an average percentage score of 97.41% (very valid). The practicality test showed an average percentage score based on the results of the response questionnaire of 95.93% (very practical) and the results of the implementation observation sheet of 93.99% (very practical). The effectiveness test showed an average evaluation test sheet score of 88.15 and an average percentage of critical thinking indicator achievement of 88% (very effective). E-LKPD mushroom material is suitable for use in learning based on the results of validity, practicality, and effectiveness tests. E-LKPD can also be used as alternative teaching material on mushroom material in schools to train students' critical thinking skills.
