Validitas dan Reliabilitas Ujian SOCA (Students Oral Case Analysis): Studi di Salah Satu Fakultas Kedokteran di Indonesia
Abstract: Medical faculty has
to make sure that the students meet the minimal competence needed using
apropriate exam. While the exam itself should facilitate students to learn.
Oral examination has known for its ability to facilitate students learn but low
in validity and reliability. Medical faculty of Lampung University (FK Unila)
apply the student oral case analysis (SOCA) exam as one of block assessment
component, as with MCQ, tutorial, and laboratory exam. This study aimed to
evaluate validity and reliability of SOCA examination at FK Unila
Method: Video of 65 students doing SOCA examination and 28 question
rubrics had taken when odd semester exam year 2014-2015 has been carying out at
FK Unila. Video and question rubrics were assessed by 5 panelis and analysed
using Lawshe's content validity ratio (CVR) to determinate its content
validity. Students performance on the video were re-assessed by another
assessor to see inter-rater reliability, than analysed using kappa Cohen. Two
expert in medical education assessed the cognitive comlpexity of the question
rubrics. Data of SOCA's student's mark from year II, III, and IV were analysed
for construct valdity and internal consistency.
Results: 93,7% of the overall question in 65 video were valid
(CVR>99%) and 71,8% question number in 28 question rubrics also valid
according to 5 panelis. SOCA cognitive complexity were at level of analyse,
know how and 4a. Inter-rater reliability analysis showed 0,549 (moderate
agreement) kappa value. Mann Whitney analysis for construct validity showed no
significant difference of all year. Cronbach alpha analysis showed internal
consistency at the point 0,575.
Conclusion: FK Unila's SOCA of odd semester examination year 2014-2015
has sufficient content validity, sufficient cognitive complexity and sufficent
inter-rater reliability but lack in construct validity and internal
consistency.
