During the 2018-2019 school year, a group of Heritage teachers made a commitment to collaborate on a Texas Education Agency program. The program is called the Texas Lesson Study. The lesson study requires teachers to work together to develop, teach and assess research based lessons. The goal of the lesson study is to help teachers across the state improve their effectiveness in the classroom by using these research-based lessons. Elizabeth Lopez and Melissa Martinez, both 5th grade teachers during the 2018-2019 school year worked together to create a lesson. Many long hours were spent analyzing data and researching best strategies to create their lesson. The following semester, Ms. Lopez and Ms. Martinez served as facilitators for Venessa Cerda, Angel Monroy, and Karla Montemayor. At the time, Ms. Cerda and Ms. Monroy taught 1st grade and Ms. Montemayor taught 2nd grade. These five teachers continued the process to develop two lessons. The lessons were submitted to the Texas Education Agency. All three lessons developed by the teachers were approved for publication. The teachers were recently notified of this distinguished honor. The lessons will be available through Texas Gateway. These dynamic, research-based lessons will help teachers from across Texas improve their instruction. We are proud of the work these five teachers did.
