Explaining and Modeling Content

Proficiency

Explaining and Modeling Content (EMC) is important in teaching, especially when it comes to learning abstract scientific concepts.

During my Student Teaching Semester (Jan-Apr 2024), I had the chance to develop my proficiency in EMC.

NGSS Standard:

  • HS-LS1-1. Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins, which carry out the essential functions of life through systems of specialized cells.
  • Structure of Content: When teaching the difference between each type of cell division, I designed a plan targeted to help students master the difference between meiosis and mitosis and to apply that to understanding genetic variation. I used a hierarchy of Big Ideas and key skills to drive the lesson based on student input.

“Your learning target today should be very clear to students, you include it as part of your opening greeting/agenda, and you also refer to it for each segment of class.” – OU Supervisor

  • Presentation: I framed the Big Idea in a way that was accurate and relevant by connecting the content to me personally (ex. my red hair that neither of my parents have). I used voice and movement, making an effort to use precise vocabulary. I modified the content to make it accessible for all students using Universal Design for Learning.
  • Visuals and Representations: I used visuals to enhance learning and ideas, including representations accessible to all and offering clarity to student understanding. I gave verbal and written instruction as well as provided visual models for complex ideas. I broke apart a huge concept into smaller chunks to help students understand each step before moving forward.
  • Modeling: I intentionally modeled the thought process students are learning and expected to do. The modeling was clear and appropriate for the learning goal.

“This feels much more relaxed and spontaneous than it did back in the fall! You’ve found your voice and teacher persona, and the students respond to your expertise in the content and your care for them.” – OU Supervisor
