After obtaining the necessary legal and ethical permissions for data collection, the research will commence. During this stage of the study, participants who agree to take part in the research will be asked to fill out the informed consent form. To obtain the pre-test data for the research, all forms will be filled out.

Students receiving standard care and continuing practice will be provided with information about the research. Pre-test and post-test data from the control group will be obtained concurrently with the study groups.

To obtain the pre-test data for the research, all forms will be filled out. According to the prepared educational materials for medical devices, students will be trained using the teach-back method. After the training, students will be asked to demonstrate their skills in using medical devices then two weeks after the pre-test. The researcher will use the Medical Device Usage Competency Observer Evaluation Form to assess the student's competency in using medical devices and Medical Device Usage Competency Knowledge Test and the Medical Device Usage Competency Self-Assessment Form for post-test data.

After obtaining the pre-test data, students will be sent educational videos related to medical devices and asked to watch them. Then two weeks after sending the videos, students will be requested to demonstrate their skills in using medical devices. The researcher will assess the students' medical device usage competencies using the Medical Device Usage Competency Observer Evaluation Form, Medical Device Usage Competency Knowledge Test, and the Medical Device Usage Competency Self-Assessment Form for post-test data.

According to the prepared educational materials for medical devices, students will be trained using the teach-back method.

The Medical Device Usage Competency Self-Assessment Form is a tool used to assess an individual's self-perceived competency in using medical devices. It typically consists of a series of questions or statements related to different aspects of medical device usage, such as knowledge, skills, and confidence. A research form has been developed by the researcher through a literature review. The content validity of the form will be determined and Cronbach's Alpha coefficient will be examined. The form is designed using a five-point Likert scale to capture participants' opinions on medical device usage competency.

It typically consists of a series of questions or scenarios related to different aspects of medical devices, including their purpose, indications, proper usage techniques, safety precautions, troubleshooting, and maintenance. The test aims to evaluate the individual's factual knowledge and comprehension of essential information related to medical device usage. Knowledge Test has been developed by the researcher based on the literature review. Expert opinions will be sought to validate the content of the test. The test will consist of multiple-choice and true/false questions.

It is typically completed by trained observers or evaluators who assess the individual's performance in using medical devices based on specific criteria. The form serves as a standardized assessment tool to gather objective data on the individual's practical skills and abilities in handling medical devices. The form has been developed by the researcher based on the available literature. The content validity of the steps in the form will be determined based on expert opinions.
