I use the Closing Bell strategy to bring my students back together as a community at the end of each class to check for understanding, debrief the class, give "grows and glows," and/or preview what we will be doing the following day. Building in this type of closing at the end of class is especially important in a blended classroom when students are spending so much time working independently or in groups.
My colleagues and I use a variety of hand signals in our classroom to avoid unnecessary disruptions and maintain focus and time on task. Three common hand signals: a signal to use bathroom; a signal for needing scrap paper; and a signal for asking a presenter to speak louder. We introduce all of the hand signals to students at the beginning of the year in a community-wide Town Hall Meeting.
When I am the teacher-artist, I consider the personalities and work ethic of students. If there are chatty students or students who are going to end up in a conflict, I cannot put them in the same group because of the nature of not being able to facilitate all of the students at once. In this instance, it is more important to create groupings that promote a harmonious learning environment. There are times when I form groups based on pre assessment or skill deficits. When the instructional focus is writing or the writing process, I found that grouping students with the same instructional need for that particular set of writing prompts has produced the most gains. These homogeneous groups allow students to practice a skill with their peers and for the small group instruction to be more targeted and specific to the needs of the learners. There may be a group of students who are struggling with the thesis statement for a particular prompt or may have difficultly connecting the content to writing process. These students would be placed in the same group.
Even with the best set of directions students still needed some guidance or individual assistance. My school currently uses a full inclusion model (Special Education students are included in the general education classes) and SPED students often need additional support. I want all my students to learn to be independent and take ownership of their learning but I also do not want them to "suffer in silence" if they need help or are incapable of access the material. Having a co-teacher adds an extra set of hands and eyes to the classroom and gives my the flexibility to even create multiple classrooms within the class.
