The decoding boards, which are your basic dry erase boards, help students visually see what their brains do as they read which is looking for blends, digraphs, long/short vowels etc. Rather than simply reading off the board, I have students write the words we practice in phonics and write the diacritical marks that support and show them how to decode words along the way that then support their reading.
My school's Blended Learning Coordinator was hired to provide blended learning support. He is provided with our schedules so that he can monitor usage and provide support if needed. While this does not mean that he is present in the classroom daily throughout the use of BL, he does try to walk around and address immediate concerns that students may need addressed. If immediate action is required a quick text can be sent to him and he'll make his way towards the classroom as well.
Struggling readers often struggle for various reasons. These can include a lack of understanding of phonics skills or not knowing the grade level sight words. This strategy shows a student undergoing a round of sight word practice by having him read a word on a card or post-it. This strategy allows the student to self assess by sorting words that he can read or can't read. By providing a visual of how many he knows versus how many he doesn't know allow him to feel successful, but at the same time understand that before his "I Can Read" pile grows larger, he will need to study all the difficult words he didn't know.
Communicating and collaborating with both colleagues and students' families is crucial in a blended environment. This is especially true if a teacher is doing something that looks very different from other teachers at his school. Check out how Raul communicates and collaborates with both his colleagues at school and his students' families and how his methods of communication and collaboration have evolved over time.
