Abstract

Setiap tahun, ada anak didik dari SMAN 2 Yogyakarta yang melanjutkan pendidikan dan lolos seleksi masuk perguruan tinggi negeri untuk program studi Biologi dan program studi Biologi Terapan. Penelitian ini bertujuan untuk mencari kecocokan model item response theory dengan instrumen penilaian akhir tahun tes Biologi di SMAN 2 Yogyakarta yang diujikan pada tahun pelajaran 2021/2022. Penelitian ini merupakan penelitian deskriptif kuantitatif. Instrumen tersebut dianalisis berdasarkan item fit dan parameter butir dengan responden sebanyak 287 yang telah memilih opsi dari 40 butir yang tersedia. Teknik pengumpulan data dilakukan dengan metode dokumentasi dan data dianalisis menggunakan software R. Hasil penelitian menunjukkan bahwa instrumen tersebut memiliki karakter yang cocok dengan model item response theory satu parameter. Butir fit dan butir valid disarankan untuk disimpan, sedangkan butir tidak fit dan butir tidak valid sebaiknya diganti dengan butir yang baru pada rekonstruksi instrumen selanjutnya, karena sudah tidak memenuhi syarat standar membuat instrumen. Khusus butir 16 disarankan merevisi pertanyaan, kunci, dan opsinya. Item analysis model of biology test instrument for the end-of-year assessment using item response theory Abstract: Every year, students from SMAN 2 Yogyakarta continue their education and pass the selection to enter state universities for Biology and Applied Biology study programs. This study aims to fit the item response theory model with the Biology end-of-year assessment instrument at SMAN 2 Yogyakarta, which is tested in the 2021/2022 academic year. This research is quantitative descriptive research. The instrument was analyzed based on item fit and item parameters with 287 respondents who had selected options from 40 available items. The data collection technique was carried out using the documentation method, and the data were analyzed using R software. The results showed that the instrument has a character that fits the one-parameter item response, theory model. Fit items and valid items are recommended to be kept, while non-fit items and invalid items should be replaced with new items in the next instrument reconstruction because they do not meet the standard requirements for making instruments. For item 16, it is recommended to revise the question, key, and options.

Abstract

This study is developmental research that aims to develop a numeracy literacy instrument based on computational thinking in mathematics learning, using the Plomp model to ensure the quality and relevance of the instrument. Selection of respondents using Cluster Random Sampling involving 220 grade 8 students at 5 State Junior High Schools in Bantul Yogyakarta, the instrument was tested for content validity using the Aiken method, resulting in an average validity score of 0.81, indicating that the instrument is valid. Confirmatory Factor Analysis (CFA) results showed that all latent variables had loading factor values above 0.5, these items more accurately represent numerical literacy abilities based on the computational thinking being measured.. Construct Reliability (CR) and Average Variance Extracted (AVE) analysis show that all dimensions meet the criteria, although the Problem Decomposition dimension requires more attention to its indicators because its AVE value is only slightly above the minimum limit. This study is limited to a relatively small number of respondents, so it is necessary to expand the sample coverage to increase the generalizability of the results. This research develops an effective instrument to improve mathematics learning and prepare students for final exams such as the Asesmen Standardisasi Pendidikan Daerah (ASPD) with better numeracy literacy skills.
