Intervention group students will be practiced with the "Lactation Simulator", a high-reality simulator, in the simulation laboratory, accompanied by a scenario.

Lactation Simulation Model (LSM) is a high fidelity simulator and is an applied and wearable breastfeeding model that educators can use for interactive training. LSM can be worn like a t-shirt and is placed over the shoulders and placed on the chest, then secured with a seat belt from the back. Thus, the seat belt can be adjusted for every size and weight. LSM is a simulator with the ability to respond to hand manipulation.

Thanks to this feature, simulated milk release occurs when pressure is applied to the breast tissue, which is approximately 3 cm behind both nipples. It is also a suitable model for expressing milk by hand or with a pump. LSM has four different skin tones. The fact that LSM can be applied on clothing contributes significantly to the protection of privacy.

Control group students will practice on a simple breast model within the scope of classical education.

Simple Breast Model: Can be used to teach and practice breast palpation techniques. The breast has real female breast size, skin color and elastic softness. Institutional permission will be requested for the "Simple breast model" in the basic skills laboratory of the Midwifery Department of Hamidiye Faculty of Health Sciences.

In this form, created by the researchers based on the literature, the participants' age, high school they graduated from, previous simulation training, etc. questions are included.

The scale was developed by Karataş and Kelleci in 2020. The four-dimensional scale, which consists of 18 valid and reliable items and is called "symptom identification", "use of information", "intervention" and "diagnosis", is a 5-point Likert type. Item, internal consistency and test-retest analyzes were used for the reliability of the scale and it was determined that the internal consistency coefficient was 0.93 and its sub-dimensions were between 0.80 - 0.93.

The form of the scale used for adults was created by Korkut Owen and Demirbaş-Çelik (2017) by adapting it to the communication skills scale. The scale consists of 25 items and 5 sub-dimensions. The first subscale, consisting of nine items, is called basic skills and self-expression. The second sub-dimension is called paying attention to communication and consists of five items. The third sub-dimension, called willingness to establish relationships, consists of three items. The fourth sub-dimension, called active listening and non-verbal communication, consists of five items. The last sub-dimension, compliance with communication principles, consists of three items. Cronbach's alpha coefficient was calculated for the internal consistency reliability of the scale and the internal consistency coefficient of the scale was found to be .94.
