Abstract:

With the expansion of science, technology, engineering, and mathematics schools, one of the major goals is to educate the teachers how to apply STEM pedagogy into their classrooms. The purpose of this article is to present a methodology for teachers training in the discipline informatics and information technologies.

Introduction:
Skills of STEM (science, technology, engineering and maths) are becoming increasingly important part in today’s society. Occupations in STEM-related careers are some of the fastest growing and best paid of the 21st century, and they often have the greatest potential for job growth.
Project-based learning is becoming increasingly successful and more preferred from the secondary school and vocational high school teachers. With project-based learning (PBL), learners get interesting experiences at the time of experimenting, and on the other hand they have a much fuller knowledge of the subject matter.
STEM Project-Based Learning (PBL) requires a professional teaching force empowered with the skills necessary for designing learning experiences that maximize student potential. Therefore, effective STEM PBL requires teachers to experience high quality professional development to learn how to design high quality experiential learning activities [1].

Teacher education for using STEM pedagogy:
The teacher training to apply the STEM methodology in their classrooms is held in club "Roboti-Byala". The education goes through the following stages:
• Presentation the STEM methodology of the teachers.
• Encouraging the creative potential of teachers.
• Presentation the hardware robotic platform (robot) designed to teach students in the elective faculty classes.
• Educating the teachers to acquire the necessary knowledge in the fields of Electronics, Electrotechnics and Mechatronics.
• Educating the teachers to work with the block programming system.
• Educating the teachers to acquire skills for creating a lesson plan based on STEM training methodology.
• Solving practical tasks based on the learning hardware platform by Learner Teachers.
• Solving practical tasks based on the learning hardware platform for teachers.
• Practical development of a lesson plan based on STEM training methodology. Presentation of the lesson in front of the group.
Example:
• Develop a lesson on "Creating a model of automated air-conditioning system management for an office premise".
• Develop a mathematical model of control of the Sense factor, which is formed by the measured temperature and humidity in the room.

The model is used to control the climate system:
• Understand the principle of operation of temperature and humidity sensors DS18B20 and DHT11.
• Learn how to manage electrical consumers using a control relay.
• Create a lesson plan.
• Analyze feedback on simulation.

The teacher has a robotic learning platform that has an integrated temperature sensor DS18B20 and a temperature and humidity sensor DHT 11. Every teacher should:
• Develop an algorithm using block programming to periodically measure temperature and humidity using the two DHT 11 and DS18B20 sensors.
• To create a mathematical model that uses the measured temperature and humidity data in order to determine the Sense factor, which by mathematical dependence calculates how a person feels the combination of temperature and humidity of the environment.
