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

Teori respon butir memiliki banyak kelebihan Ketika digunakan untuk menentukan karateristik butir instrumen jika ukuran sampel yang digunakan besar. Sebaliknya, jika ukuran sampel kecil IRT memiliki kecenderunga kurang akurat dalam menentukan karakteristik suatu instrumen. Penelitian ini bertujuan untuk menentukan efek ukuran sampel pada GRM yang didasarkan pada data awal yang memiliki korelasi inter item yang sama secara statistik. Penelitian ini merupakan penelitian simulasi yang didasarkan pada data empiris. Data skunder dari 43 responden digunakan sebagai data awal. Akurasi efek dari ukuran sampel baru dihitung dengan menggunakn RMSE dan koelasi. Teknik membangkitkan data yang digunakan yaitu metode multivariat variabel random diskrit. perangkat lunak R. Hasil penelitian menunjukkan nilai RMSE berkisar 0,6 > 0,33 dan korelasi sekitar 0,5 < 0,7 tidak memenuhi standar akurasi.. Dapat disimpulkan bahwa ukuran sampel dengan matriks korelsi yang sama, tidak memiliki efek pada parameter GRM dan data baru yang dihasilkan tidak dapat digunakan untuk pemulihan parameter GRM The effect of sample size on GRM parameters based on the correlation between items Abstract: Item response theory has many advantages in determining the instrument's item characteristics when the sample size used is large. On the other hand, if the sample size is small, the IRT tends to be less accurate in determining an instrument. This study aims to determine the effect of sample size on GRM based on the inter-item correlation matrix of initial data. This research was conducted on simulation research based on empirical data. Secondary data from 43 respondents was used as initial data. The effect accuracy of the new sample size was calculated using RMSE and correlation. The data generation method used was the multivariate method of discrete random variables. The results show that the RMSE value is around 0.6 > 0.33, and the correlation of about 0.5 < 0.7 did not meet the standard of accuracy. It could be concluded that the sample size with the same inter-item correlation matrix has no effect on the GRM parameters, and the new data generated couldn’t be used for GRM parameter recovery.
