“…The difference in the level of difficulty can be caused by the placement of the order of questions (Debeer & Janssen, 2013). Cognitive assessment instruments that have been tested and analyzed for validity, reliability, discriminating power and difficulty level can be used as an appropriate measuring tool in a learning process (Lia et al, 2020).…”

The existence of cognitive assessments in learning media that does not require much consideration for their feasibility as a measuring tool is one of the problems that arise because it can cause misinformation obtained by the teacher. The purpose of this study was to determine the construct validity and content of the cognitive assessment instrument and the validity of the questions, the reliability of the questions, the distinguishing power of the questions, and the level of difficulty of the questions on the cognitive assessment instruments to be used in general biology learning media. The research method used is descriptive quantitative through a survey involving one expert and 58 students of the Biology Education study program of IKIP Budi Utomo. The research limitation is a cognitive assessment of microbiology material in general biology courses. The type of instrument analyzed is a test. The results obtained are that the cognitive assessment instrument has a valid level of validity from the aspect of construct and content, the validity of the questions in the valid category, the reliability of the questions is moderate, the discriminatory power of the questions is good, and the level of difficulty of the questions is moderate. The conclusion is that the cognitive assessment instrument is appropriate to be used as an appropriate measuring tool for microbiology material in general biology learning media.

“…These results indicate that the unidimensionality of the instrument with a minimum value of 20% is fulfilled (Smits, et al, 2011;Wu, et al, 2013;Sumintono & Widhiarso, 2015). The instrument developed can measure what should be measured (Lia, et al, 2020). The unexplained variance was 6.6; 5.7; 3.3; 3.2; and 3.1.…”

“…The separation value of person (2.23) and item (6.21) is also good category, because according to Linacre (2016), the separation index value is said to be good if it is greater than 2.0 and the separation person and item index is an additional measurement very important for the evaluation of a measuring instrument (Boone, et al, 2014). Separation reliability (item or person reliability) is categorized as high value because the research sample and the difficulty level of the item have a wide range and results in small measurement errors (Lia, et al, 2020). This indicates that the item has a difficulty level from easiest to most difficult.…”

Information about score obtained from a test is often interpreted as an indicator of the student's ability level. This is one of the weaknesses of classical analysis that are unable to provide meaningful and fair information. The acquisition of the same score if it comes from a test item with a different level of difficulty, must show different abilities. Analysis of the Rasch model will overcome this weakness. The purpose of this study was to analyze the quality of the items by validating the national chemistry exam instrument using the Rasch model. The research sample was 212 new students of the Department of Chemistry at the State University of Medan. The data collected was in the form of respondent's answer data to the 2013 chemistry UN questions, which amounted to 40 items multiple choice and uses the documentation method. Data analysis technique used the Rasch Model with Ministep software. The results of the analysis show the quality of the Chemistry National Exam (UN) questions is categorized as very good based on the following aspects: unidimension, item fit test, person map item, difficulty test level, person and item reliability. There is one item found to be gender bias, in which men benefit more than women. The average chemistry ability of respondents is above the average level of difficulty of the test items

“…Perhitungan validasi melalui Aiken tergolong baik dengan reliabilitas sembilan sekolah tidak memenuhi syarat serta reliabilitas yang baik, sehingga instrumen yang digunakan menjadi baik (Iswanto, 2017). Lia et al (2020) menjelaskan jika alat tes nya sudah terbukti untuk validitas isi, validitas konstruk, reliabilitas antar penilai, dan reliabilitas dengan Raschmodel. Instrumen tes telah memenuhi validitas isi dengan penilaian ahli yang dibuktikan dengan perolehan indeks persetujuan (Indeks Aiken) mulai dari 0,50 hingga 1,00.…”

Tujuan penelitian ini untuk mengetahui validitas isi instrumen komitmen tugas bermain sepakbola melalui analisis indeks Aiken. Subjek penelitian ini adalah dosen dan pelatih siswa SSO Real Madrid Fakultas Universitas Negeri Yogyakarta. Instrumen yang digunakan adalah instrumen pengukuran komitmen tugas bermain sepakbola yang terdiri dari lima indikator, yaitu: 1) kapasitas untuk mendalami teknik dalam sepakbola yang ditekuni; 2) ketekunan menjalani pelatihan sesuai dengan program latihan; 3) daya tahan mental dalam berlatih dan berlaga; 4) keyakinan diri mampu; dan 5) dorongan untuk berprestasi. Pengukuran validitas instrumen menggunakan analisis Aiken yang melibatkan enam (6) orang rater sebagai penilai. Hasil penelitian adalah: 1) diperoleh validitas isi instrumen pengukuran komitmen tugas bermain sepakbola pada aspek kapasitas teknik diperoleh nilai terendah 0.83 dan tertinggi 0.88; pada aspek ketekunan diperoleh nilai terendah 0.83 dan tertinggi 0.88; pada aspek daya tahan mental diperoleh nilai terendah 0.83 dan tertinggi 0.88; pada aspek dorongan berprestasi diperoleh nilai terendah 0.83 dan tertinggi 0.88; dan pada aspek kapasitas teknik diperoleh nilai terendah 0.83 dan tertinggi 0.92. Aiken index analysis to measure the validity of the content of the soccer-playing task commitment instrument AbstractThe research intends to determine the content validity of the task commitment of playing football through an analysis of the Aiken index. Research subjects were lecturers and trainers of SSO Real Madrid students of the Faculty of Sport Sciences Universitas Negeri Yogyakarta. The instrument used was by measurement instrument of the commitment of playing football consisting of five indicators: (1) the capacity to explore the techniques in football that are occupied; (2) perseverance following training in accordance with the training program; (3) mental endurance in practising and competing; (4) confidence of being able; and (5) encouragement for achievement. Measurement of instrument validity used Aiken analysis involving six (6) raters as assessors. The research results are: (1) is obtained the content validity of the instrument measuring the task commitment of playing football on technique capacity aspect that is taken the lowest value 0.83 and the highest 0.88; in the perseverance aspect, the lowest value is 0.83 and the highest 0.88; in the mental endurance aspect, the lowest value is 0.83 and the highest 0.88; on the achievement encouragement aspects, the lowest value is 0.83 and the highest 0.88; and on the technique capacity aspect, the lowest value is 0.83 and the highest 0.92.
