SKRIPSI INVESTIGATING DIFFICULTY LEVEL, DISCRIMINATION INDEX, AND COGNITIVE DOMAIN OF THE ENGLISH FORMATIVE TEST ITEMS OF THE TENTH GRADERS OF SMK CITRA MEDIKA
ELT involves several stages of learning, from planning to evaluation. One
form of evaluation is assessment, and one tool for assessing students is testing. One
type of test is a formative test. Formative tests should be tailored to students'
abilities and support learning outcomes. At SMK Citra Medika, teachers have never
conducted formative test item analysis. Therefore, the formative test used at SMK
Citra Medika is unstandardized in the form of the assessment standards. The
purpose of this undergraduate thesis is to find out the test items, especially how the
Difficulty Level, Discrimination Index, and Cognitive Domain of the English
Formative Test Items of the Tenth Graders of SMK Citra Medika.
This study employed a mixed-methods approach, specifically an explanatory
sequential mixed-methods approach. The difficulty level and discrimination index
were analyzed quantitatively using the ANATES application. Meanwhile, the
cognitive domain was analyzed qualitatively through three stages: data
condensation, data display, and conclusion drawing/verification.
The results show that the difficulty level of the valid English formative test
items is classified as 43.2% medium difficulty (accepted), and 56.8% as easy
(revised or reserved). The writer concludes that the difficulty level of the English
formative test items of the tenth graders of SMK Citra Medika Kota Magelang in
the school year 2024/2025 is classified as easy. Moreover, the discrimination index
is classified as 37.8% satisfactory, 56.8% good, and 5.4% excellent. All of the test
items in this study are 100% accepted, and 56.8% of the 100% test items have an
ideal (good) discrimination index. The writer concludes that the quality of the
discrimination index of the English Formative test items of the tenth graders of
SMK Citra Medika Kota Magelang in the school year 2024/2025 has a good
discrimination index because the test items can differentiate students with high
ability and students with low ability well. Additionally, the result of the cognitive
domain covered C1 (21.6%), C2 (56.8%), C3 (2.7%), C4 (16.2%), C5 (0%), and
C6 (2.7%). The writer concludes that the English formative test questions of the
tenth graders of SMK Citra Medika Kota Magelang in the school year 2024/2025
are dominated by questions at the C2 (Understand) cognitive level and fall under
the LOTS category. Therefore, to provide a more comprehensive assessment and
encourage maximum student development, further research is needed to assess and
ensure a good difficulty level, discrimination index, and cognitive domain in
formative tests.
