N1  - Penelitian ini bertujuan untuk mengembangkan instrumen literasi STEM pada 
konsep bioteknologi, mengetahui kelayakan instrumen berdasarkan uji ahli, serta 
mengetahui respon pengguna terhadap instrumen tes yang dikembangkan. 
Penelitian ini menggunakan metode Research and Development (R&D) dengan 
desain Berkeley Evaluation and Assessment Research (BEAR) Assessment System 
yang meliputi tahap construct map, item design, outcome space, dan measurement 
model. Instrumen yang dikembangkan terdiri atas tes pengetahuan literasi STEM, 
kuesioner sikap STEM, dan lembar observasi keterampilan STEM. Validasi 
instrumen dilakukan oleh lima ahli, sedangkan uji coba tes pengetahuan melibatkan 
126 peserta didik SMA di Provinsi Banten. Analisis data dilakukan menggunakan 
model Rasch dengan bantuan program R (eRm package). Hasil uji kelayakan 
menunjukkan bahwa instrumen layak digunakan dengan catatan perlu dilakukan 
revisi. Analisis model Rasch menunjukkan bahwa instrumen tes pengetahuan 
literasi STEM memenuhi kriteria reliabilitas pada kategori cukup reliabel sebesar 
0,6708, valid serta kemampuan peserta didik lebih tinggi daripada tingkat kesulitan 
soal. Respon peserta didik terhadap instrumen tes berada pada kategori praktis 
dengan rata-rata sebesar 77%. Dengan demikian, instrumen yang dikembangkan 
dapat digunakan sebagai alat evaluasi literasi STEM peserta didik pada 
pembelajaran biologi SMA.

N2  - This study aimed to develop a STEM literacy instrument on biotechnology concepts, 
to determine the feasibility of the instrument based on expert judgment, and to 
examine users? responses to the developed test instrument. The study employed a 
Research and Development (R&D) method using the Berkeley Evaluation and 
Assessment Research (BEAR) Assessment System design, which consists of the 
construct map, item design, outcome space, and measurement model stages. The 
developed instruments comprised a STEM literacy knowledge test, a STEM attitude 
questionnaire, and a STEM skills observation sheet. Instrument validation was 
conducted by five experts, while the field test of the STEM literacy knowledge test 
involved 126 senior high school students in Banten Province, Indonesia. Data were 
analyzed using the Rasch model with the assistance of the R program (eRm 
package). The feasibility test results indicated that the instrument was suitable for 
use with necessary revisions. Rasch model analysis revealed that the STEM literacy 
knowledge test demonstrated acceptable reliability (0.6708), satisfactory validity, 
and that students? average ability was higher than the item difficulty level. Students? 
responses to the test instrument fell into the practical category, with an average 
percentage of 77%. Therefore, the developed instrument can be used as an 
evaluation tool to assess students? STEM literacy in senior high school biology 
learning.
