Profil dan Validitas Instrumen Penilaian Autentik pada Materi Sel

Profile and Validity of Authentic Assessment Instruments on Cell Material

Penilaian autentik yaitu proses penilaian secara utuh yang dapat menilai kesiapan peserta didik, proses dan hasil belajar. Pembelajaran pada materi sel dapat lebih bermakna dengan menggunakan penilaian autentik karena penilaian autentik tidak hanya menilai pengetahuan tetapi juga menilai sikap dan keterampilan peserta didik. Namun, instrumen penilaian autentik sebagian besar belum dikembangkan dan diimplementasikan dibeberapa jenjang pendidikan. Kondisi tersebut bertentangan dengan tuntutan penilaian pada kurikulum 2013 yang menuntut semua aspek kompetensi peserta didik diukur dalam penilaian. Penelitian ini bertujuan menghasilkan instrumen penilaian autentik materi sel yang valid. Pengembangan instrumen penilaian autentik menggunakan model R&D dengan 6 tahapan yaitu melakukan pengamatan potensi dan masalah, mengumpulkan informasi untuk merancang instrumen penilaian, mendesain produk instrumen penilaian disesuaikan dengan tuntutan kurikulum 2013, validasi desain dengan cara validator memberikan saran terhadap instrumen penilaian yang telah dikembangkan, merevisi desain produk sesuai saran validator dan uji coba terbatas. Namun penelitian ini hanya sampai pada tahap revisi desain produk tanpa melakukan uji coba terbatas karena adanya pandemi covid-19. Kelayakan instrumen penilaian didapatkan dengan metode validasi oleh 3 validator. Instrumen penilaian autentik yang dihasilkan layak ditinjau dari aspek ranah isi sebesar 3,71, kontruksi sebesar 3,93 dan bahasa sebesar 3,83 sehingga rata-rata keseluruhan sebesar 3,82 dengan kategori sangat valid. Penelitian ini menghasilkan instrumen penilaian autentik materi sel masing-masing disertai petunjuk penggunaan meliputi penilaian diri sikap spritual, penilaian sikap sosial oleh guru, penilaian pengetahuan beserta kisi-kisi dan kunci jawaban, penilaian keterampilan proses dan kunci jawaban serta keterampilan kinerja laporan praktikum yang berguna untuk mengukur sikap, pengetahuan dan keterampilan peserta didik.

Authentic assessment, namely the whole assessment process that can assess the readiness of students, the process and learning outcomes. Learning on cell material can be more meaningful by using authentic assessments because authentic assessments do not only assess knowledge but also assess the attitudes and skills of students. However, most authentic assessment instruments have not been developed and implemented at several levels of education. This condition is contrary to the demands of the assessment in the 2013 curriculum which demands that all aspects of the competence of students be measured in the assessment. This study aims to produce an authentic assessment instrument on valid cell material. Development of authentic assessment instruments using the R and D model with six stages, namely observing potentials and problems, collecting information to design assessment instruments, designing assessment instrument products according to the demands of the 2013 curriculum, validating designs by means of validators providing suggestions on assessment instruments that have been developed, revising designs products according to validator suggestions and limited trials. However, this research only reached the stage of product design revision without conducting limited trials due to the Covid-19 pandemic. The feasibility of the assessment instrument was obtained by the validation method by three validators. The resulted authentic assessment instrument include of the content aspect of 3.71, construction of 3.93 and language of 3.83 so that the overall average is 3.82 with a very valid category. This study produced an authentic assessment instrument on each cell material accompanied by instructions for use including self-assessment of spiritual attitudes, assessment of social attitudes by teachers, assessment of knowledge along with grid questions and answer keys, assessment of process skills and answer keys and skills performance in the form of a practicum report which is useful for measuring attitudes, knowledge and skills of learners.
