An analysis of the mathematics school examination test quality

Abstract

This research aims to describe: (1) the quality of mathematics school examination test of the Junior High School for the academic year 2015/2016 in Kabupaten Bangkalan based on qualitative analysis of tests item, (2) ) the quality of mathematics school examination test of Junior High School for the academic year 2015/2016 in Kabupaten Bangkalan based on quantitative analysis of test items, and (3) the test equating on mathematics school examination test for the academic year of 2015/2016 of Junior High School in Kabupaten Bangkalan. A test is said to be quality if it fulfills validity, reliability, and it has good characteristic. A test is said to be equivalent to another if the test scores of one test can be exchanged with the scores of another test. The data is taken from school examination script accompanied with the answer sheets of students. Qualitative data analysis was conducted with the help of experts judgement. Quantitative data analysis was conducted with Classical Test Theory by Iteman and Item Response Theory by BilogMG. These programs are used to find out the test quality quantitatively. In order to analyze the equivalence between series of tests, item-characteristic curves were used. These curves were drawn by Geogebra. The research result shows: (1) qualitatively, the test plan quality of mathematics school examination test is quite good. Meanwhile, the school exam quality is quite good and not so good, (2) quantitatively, the school examination test quality is good, and (3) equating, based on the item-characteristic curves, the school examination tests is equal.

The Equivalence of Toep Forms

“…When a test is developed in several parallel forms, it is very important to ensure the equivalence of the test forms (Baghaei, 2010;Kartowagiran et al, 2018;Retnawati, Kartowagiran, Arlinwibowo, & Sulistyaningsih, 2017;van der Linden, 2013;von Davier & Wilson, 2007). This is to ensure the test forms used are fair for all test takers (Baghaei, 2010;Kartowagiran et al, 2018;Meyer & Zhu, 2013;Retnawati et al, 2017).…”

“…One of them was by Yim and Huh (2006), who investigated the equivalence of the Medical Licensing Examination forms in 2003 and 2004 by employing the item response theory approach, the results of which indicated that the Medical Licensing Examination in 2003 was more difficult than that in 2004. Sutrisno's (2016) study which investigated the quality of the school mathematics test in Bangkalan Regency, Indonesia, found that by using the test characteristics curve, the five test forms examined were found to be well equated. A study by Kartowagiran et al (2018) investigated the equivalence of the National Examination forms in Indonesia from 2013-2016 by using the means-sigma.…”

Determining The Health Literacy Levels of Students in The Faculty of Health Sciences and Comparing them with Students from Other Faculties

“…Verilerin güvenilirliğinde Kuder Richardson 20 katsayısından yararlanılmış olup 0,593 olarak hesaplanmıştır. Güvenilirlik analizlerinde genel kabul gören aralıklara göre 0,41-0,60 arasında kaldığı için "kabul edilebilir (quite)" aralığında olduğundan alınan yanıtlar güvenilir kabul edilmiştir (Sutrisno, 2016). Çalışmada verilerin tanımlayıcı sunumunda frekans, yüzde, ortalama, standart sapma ve çeyrekliklerden yararlanılmıştır.…”

Effect of Interactive Conceptual Instruction Assisted by PhET Simulations on the Student’s Scientific Consistency in Physics

“…The validation results using the CVI method resulted in an index value of 0.90 which is categorized as medium validity based on Irawan et al (2020), meaning that the test is valid with a medium level. Meanwhile, the field test to determine the reliability of the test using the KR-20 method resulted in an index of 0.77 which is categorized as good reliability based on Sutrisno (2016), meaning that the test is reliable which is categorized as good.…”
