Being a teacher, in general, is not an easy duty. It needs to be patient and have that personality of readiness for the claim, argues, then convinces. I think a STEM teacher is a teacher who needs to connect the facts around us to the subject that we teach.
Science and math exist in every detail of our life, and we still face the questions of what we will need this for? Why study this subject?. We need to answer these and other questions by showing how we use what we learn in real life and why they are essential. As a math teacher, I faced one of these questions from an eighth-grade student who asked: Mis, how will I use algebra in my life? How will my future relate to math if I do not work as an engineer?
Also, Teachers need to know their students and their interest and skills to connect them to what they teach. We can do something to know our students' interests is what we used to have as a warm-up activity for our eighth grade; we ask the students about their favorite subject, or if they have the chance and the power, what they may change?
