This research will be carried out to determine the effectiveness of teaching thromboembolism risk assessment during pregnancy and postpartum period to midwifery students using a high-tech simulation method.

Thromboembolism during pregnancy and postpartum period is one of the preventable causes of maternal deaths. For this reason, it is important to determine the thromboembolism risk of pregnant women and postpartum women by midwives before complications develop and to plan preventive interventions. The aim of the research is to provide midwifery students with the ability to evaluate the risk of thromboembolism before clinical experience through high-tech simulation application.

Goals;

• To increase midwifery students' skills in assessing thromboembolism risk during pregnancy and postpartum period before clinical practice.
• To increase the self-confidence and satisfaction of midwifery students with simulation application in pregnancy and postpartum thromboembolism risk assessment skills.
• To develop midwifery students' quick, critical thinking and decision-making skills in assessing the risk of thromboembolism before clinical practice.
• To help midwifery students visualize the risk of pregnancy and postpartum thromboembolism, which has an important place in terms of maternal deaths, by creating a clinical environment with a case scenario.
• To determine the effectiveness of midwifery teaching through case scenario simulation application with the risk of pregnancy and postpartum thromboembolism, and to increase students' learning and clinical practice skills.

Design of the Research: Researchers will receive scenario creation and simulation design training for the advanced technology simulation method. After the simulation training, pregnancy and postpartum thromboembolism scenarios will be prepared for the intervention group. A thromboembolism information form will be prepared for the intervention and control groups. Expert opinions will be obtained from at least 6 people who are experts in the field of risky pregnancy and postpartum on the forms and scenarios prepared by the researcher. In line with expert opinions, the scenarios and thromboembolism information form will be finalized. The scenarios and forms prepared for the intervention group will be piloted with 6 3rd year midwifery students and volunteers, and final corrections will be made.

Two groups, the intervention and control groups, will be given a 2-hour theoretical training on the risks of pregnancy and postpartum thromboembolism prepared by the researchers. Then, the "Thromboembolism information evaluation form" will be applied to the intervention and control groups. The control group will not be taught with the simulation method.

After the pilot application, the intervention group will be given a laboratory environment close to the clinical environment and will be given scenarios prepared with simulation method teaching and thromboembolism risk assessment training. The simulation application teaching period is planned to be 45 minutes in total, with the first 10 minutes of preliminary information, 15 minutes of teaching with the simulation method, and the last 20 analysis sessions. Afterwards, the thoughts of each 6 students regarding simulation training and teaching will be evaluated in the analysis sessions. Then, the thromboembolism information form and the two scales to be used will be applied to the Intervention group. It is planned to apply the same application to the intervention group twice in total, with an interval of 2 weeks.
