The competent teacher differentiates instruction by using a variety of strategies that support critical and creative thinking, problem-solving, and continuous growth and learning. This teacher understands that the classroom is a dynamic environment requiring ongoing modification of instruction to enhance learning for each student.
Rationale:
I created a screencast video on March 23, 2020 about valence electrons and their role in the periodic table. This was made to provide students with a simple and short explanation of the trends that we see. Also, it was made in reference to Illinois Learning Standard HS-PS1-1, "Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms." In the video, viewers can learn about how elements in the same period have similar properties based on their number of valence electrons.
I have been a student for so long that I cannot help but look at the world from a student's viewpoint. That being said, I tried my best to make this video interesting and engaging for learners to watch. I did this by adding some humor and even some real-life situations that happen to people every day. In doing so, I believe that I fulfilled IPTS 2N which says, "The competent teacher facilitates learning experiences that make connections to other content areas and to life experiences." I would also like to point out that IPTS 2M is in order as well. This standard says, "The competent teacher uses a variety of explanations and multiple representations of concepts that capture key ideas to help each student develop conceptual understanding and address common misunderstandings." We can see evidence of this standard in the multiple ways in which the information was presented. I showed a Bohr model, a model of an ionic bonding reaction, and a detailed explanation through the periodic table all of which were to explain key ideas about valence electrons.
In making this video, I learned that though terms may be commonplace for me, this will be the absolute first time that many students will have ever heard of these words; therefore, I must step down into the world of my students and see the world through their eyes. This was important for me because it gave me confidence in knowing that I can do this. I have a passion for science, learning, and most of all, for my students. Making this video, as meaningless as it sounds to some, was my assurance that I am not making a mistake in my choices but am following the path set before me. This video connects to my future classroom in that technology is a big deal in schools now. It shows that I can keep up with the times and use what tools I have to teach my students.
