Pengembangan Lembar Kegiatan Peserta Didik (LKPD) Berbasis Concept Attainment Model  (CAM) Subpokok Bahasan Filum Echinodermata untuk Melatihkan Pemahaman Konsep Siswa

The Development of Student Worksheet (LKPD) Based on Concept Attainment Model (CAM) in Echinodermata Phylum Materials to Train the Concept Understanding 

Abstrak

Pemahaman konsep adalah kemampuan dalam menguasai pengertian, memberikan interpretasi serta mengetahui sesuatu untuk dapat dilihat dari berbagai segi. Pemahaman konsep peserta didik dapat diajarkan melalui Concept Attainment Model  (CAM). Model pembelajaran CAM dalam penerapannya dapat dibantu melalui sumber belajar Lembar Kegiatan Peserta Didik. Penelitian ini bertujuan menghasilkan LKPD berbasis CAM subpokok bahasan Filum Echinodermata untuk melatihkan pemahaman konsep peserta didik yang layak berdasarkan validitas, kepraktisan, dan keefektifan. LKPD tersebut menggunakan desain penelitian model 4-D yang terdiri atas tahap Define, Design, Develop, dan Dessiminate, namun tahap akhir tidak dilakukan. Uji coba dilakukan pada 16 peserta didik kelas XI MIA 3 SMA Negeri 1 Ngimbang. Berdasarkan hasil validasi para ahli terhadap kelayakan isi, bahasa, penyajian serta karakteristik CAM menunjukkan bahwa LKPD dikatakan sangat valid dengan skor sebesar 3.86%. Hasil pengamatan aktivitas peserta didik dikatakan sangat praktis dengan skor sebesar 86.72%. Berdasarkan respons peserta didik memperoleh skor rata-rata 96.50% dengan kategori sangat efektif. Selain itu, Keefektifan LKPD berdasarkan hasil belajar yang ditinjau dari nilai pre-test dan post-test mendapatkan skor dengan kategori tinggi. Tes pemahaman konsep peserta didik mendapatkan skor rata-rata pada saat pre-test adalah 48.6% dan skor rata-rata post-test adalah 82.7%.

Abstract

The understanding of the concept is an ability to master the comprehensiveness, able to provide interpretation and understand something from various aspects. The understanding of students' concepts can be taught through the Concept Attention Model (CAM). The CAM learning model in its application can be assisted through learning resources in the form of Student Activity Sheets. The purpose of this study was to produce a student Activity Sheets based CAM on the subject of Phylum Echinodermata to practice proper understanding of the concepts of students based on validity, practicality, and effectiveness. The a Student Activity Sheets used a 4-D model research design consisting of the Define, Design, Develop, and Dessiminate stages, but the final stage is not carried out. The trial was conducted on 16 students of class XI MIA 3 SMA Negeri 1 Ngimbang. Based on the results of the validation of the experts on the appropriateness of the content, language, and presentation as well as the characteristics of CAM, it shows that a Student Activity Sheets to be very valid with a score of 3.86%. The results of observing the activities of students to be very practical with a score of 86.72%. Based on the responses of students, the average score was 96.50% with the very effective category. In addition, the effectiveness of a Student Activity Sheets based on learning outcomes in terms of pre-test and post-test scores got a high category score. The test of understanding the concept of students got an average score at the time of the pre-test was 48.6% and the average post-test score was 82.7%.
