The aim of this study is to examine the effect of the use of pocket cards by students taking the "Care of a Child with Special Needs" course on students' self-efficacy perceptions and course success.

1. H01. There is no difference between the self-efficacy perception scores of the students in the group who use pocket cards in the care of children with special needs course and the students in the group who do not use pocket cards.
2. H02. There is no significant difference between the course success scores of the students in the group who use pocket cards in the care of children with special needs course and the students in the group who do not use pocket cards.

The research will include the parents of 194 children with special needs between the ages of 6-18, who came to four special education and rehabilitation centers in Efeler district of Aydın province between 13 September 2021 - 22 May 2022 (8 months) and were selected by stratified random sampling method.

Study data will be collected from the parents of children coming to Rehabilitation Centers and routine training by face-to-face interview technique using the child and parent information form and the Oral and Dental Health Information Evaluation Form. Data collection is expected to take approximately 15-20 minutes.

Approval will be obtained from Aydın Adnan Menderes University Faculty of Nursing Non-Interventional Research Ethics Committee to conduct the research. Permission will be obtained from the institutions to conduct the research in the centers. An explanation about the research will be made to the parents (mother or father) of the children who meet the sampling criteria, and written consent will be obtained from the parents of the children who agree to participate in the research.

While calculating the sample size, the self-efficacy perception score averages in the study titled "The effect of learning objects on academic success, self-efficacy perception, motivation and learning permanence in mathematics teaching" were used according to effect power calculation blended standard deviation. was placed on the formula and the potency was calculated (d: 13.11). Two independent groups and t test options were selected through G power analysis and power analysis was calculated according to the two-way hypothesis method. According to the previous study, when the significance level between the study group and the control group was taken as α = 0.05 and the power of the test was 1-β = 0.95, the sample size to be selected was determined as 56 people for each group. It was determined that the sample loss (students registered for the 2018-2019 spring semester who failed due to absence and failure) was approximately 15% due to the fact that among our exclusion criteria for the study were students who failed due to absence and failure. By increasing the minimum number of students planned to be included in the research and required to be in each group (n=56+0.15) by 15% (approximately 8 students), the number of samples for both groups became 64 (study group; n=64; control group n=64). It was calculated as a total of 128 students. A post-hoc power analysis will be conducted after the study. The data of the research will be analyzed using SPSS 25 (Statistical Package for the Social Sciences) program. Descriptive statistics, Chi-square test, Student-T test will be used to evaluate the study data. Student's T Test will be used to compare paired groups in the analysis of normally distributed dependent variables. Mann-Whitney U test will be applied to compare two independent data that do not show normal distribution. Values at P<0.05 will be considered statistically significant. Regression analysis will be performed to determine factors that may be related to dependent variables.
