Participants in the intervention group were shown an educational video prepared by the researcher outlining the steps of the urine-collection procedure for infants (i.e., collecting a urine sample with a pediatric urine bag). Students performed the procedure (collecting a urine sample using a urine bag) on a baby mannequin in a laboratory setting. During this practice, they were evaluated using a checklist by two independent researchers who monitored all steps of the process.

Participants in the control group received instruction on the Infant Urine Collection procedure (obtaining a urine sample using a pediatric urine bag) through a demonstration. Students practiced the procedure in a laboratory setting using a baby mannequin (obtaining a urine sample using a urine bag). During this practice, they were evaluated using a checklist by two independent researchers who monitored all steps of the process.

A knowledge test was administered to assess participants' understanding of urine sample collection. This test was given twice to participants, both before and after the procedure.

This test, prepared by researchers in line with the literature, consists of 22 questions covering the skills required to collect urine samples from infants aged 0-1 years. The test is presented as a knowledge assessment. Expert opinions were obtained for the test, and it was revised accordingly. Questions are answered as true or false, with correct answers earning 1 point and incorrect ones earning 0. The minimum score on this test is 0, and the maximum is 22. A high score on this knowledge test indicates sufficient knowledge of collecting urine samples.

A checklist was created to assess participants' skills in collecting urine samples. This checklist was administered individually to each student.

This checklist, prepared by researchers based on the literature, consists of 20 statements covering urine sample collection skills in infants aged 0-1 years. The information form is in test format. Expert opinions were sought for the test, and the questionnaire was revised accordingly. The questions in the form were answered and calculated as follows: "Sufficient = 2 points, Partially Sufficient = 1 point, and Insufficient = 0 points". The minimum score on this checklist is 0, and the maximum is 40. A high score on this checklist indicates that the student has learned and applied the skill.
