About Erin

About Me

Hi!  My name is Erin and I have taught Science for 14 years in California.  I currently teach middle school integrated science but taught high school Chemistry and Biology for 10 years.  Also, I have a 10-year-old daughter and I love making material for her.

Why I started Sadler Science

When I made the shift to the NGSS, the transformation in my classroom was huge.  I ditched my old lecture-based strategies and put the learning in the hands of my students.  At first, it was terrifying.  And, I made a LOT of mistakes as I figured it out.  But, it was well worth it.

Now, I have a much more relaxed and comfortable classroom environment but my students are learning more.  I have more time to spend working with small groups and coaching students through problems.

My goal is to help you make this shift without making the same initial mistakes that I did.  I want to make it easy for you to make this transition in your classroom.

My Mission

My mission is to help ensure that all students have access to a high-quality, rigorous science curriculum.  Making this happen requires teachers to leave behind traditional methods of teaching science in favor of student-driven, culturally relevant practices. By making this shift, we empower all students to feel confident pursuing careers in STEM.

My Business Values:

  • Science:  All children are born scientists and have the ability to learn complex science concepts given the right environment.  Also, phenomena-based science coursework provides important context and relevance through which students can learn other subjects.  
  • Equity: I believe that all students, regardless of socioeconomic level, race, or language spoken deserve access to high-quality science education. Students should not lose access to science education to provide additional coursework in English language development, special services, etc.  I also believe that teachers must provide relevant, rigorous, and culturally relevant coursework in their classrooms in order to ensure equity. 
  • Connection: I am asking teachers to step out of their comfort zone.  As a result, students will also be asked to step out of their comfort zone.  It's vital that we build a strong community, relationships, and support to help them make this transition.
  • Facilitation: I believe that learning should be active.  This changes the traditional roles between the students and the educator.  In a student-led environment, teachers should act as facilitators.
