Families of students with disabilities and those who are culturally and linguistically diverse (CLD), are looking for better educational opportunities. Charter schools offer promise as they were designed to promote student learning with limited control from the state. Charter schools though, have been criticized for relying on exclusionary discipline policies

Families of students with disabilities and those who are culturally and linguistically diverse (CLD), are looking for better educational opportunities. Charter schools offer promise as they were designed to promote student learning with limited control from the state. Charter schools though, have been criticized for relying on exclusionary discipline policies that affect CLD students and students with disabilities disproportionately. This study was designed to understand how Arizona charter schools use exclusionary discipline practices, with a focus on students with disabilities and CLD students. Two participants, a fourth grade and fifth grade teacher from a Phoenix metropolis charter school completed surveys and interviews where they answered questions about their classroom and their school’s discipline policies. Teachers were asked how they have adapted and administered classroom discipline policies and to what extent have positive behavioral strategies been implemented in an online setting due to the COVID-19 pandemic when schools transitioned to virtual learning. The results showed that in a virtual setting, teachers retained the practice of removing students from the “classroom”, expectations had to be modified to meet the needs of the new environment, and the school counselor served in conflicting roles. The findings suggested that charter schools and teachers may be transferring and adapting their reliance on exclusionary discipline practices even for an online setting with classrooms that have students with disabilities and those who are CLD.

Social insects collectively exploit food sources by recruiting nestmates, creating positive feedback that steers foraging effort to the best locations. The nature of this positive feedback varies among species, with implications for collective foraging. The mass recruitment trails of many ants are nonlinear, meaning that small increases in recruitment effort

Social insects collectively exploit food sources by recruiting nestmates, creating positive feedback that steers foraging effort to the best locations. The nature of this positive feedback varies among species, with implications for collective foraging. The mass recruitment trails of many ants are nonlinear, meaning that small increases in recruitment effort yield disproportionately large increases in recruitment success. The waggle dance of honeybees, in contrast, is believed to be linear, meaning that success increases proportionately to effort. However, the implications of this presumed linearityhave never been tested. One such implication is the prediction that linear recruiters will equally exploit two identical food sources, in contrast to nonlinear recruiters, who randomly choose only one of them. I tested this prediction in colonies of honeybees that were isolated in flight cages and presented with two identical sucrose feeders. The results from 15 trials were consistent with linearity, with many cases of equal exploitation of the feeders. In addition, I tested the prediction that linear recruiters can reallocate their forager distribution when unequal feeders are swapped in position. Results from 15 trials were consistent with linearity, with many cases of clear choice for a stronger food source, followed by a subsequent switch with reallocation of foragers to the new location of the stronger food source. These findings show evidence of a linear pattern of nestmate recruitment, with implications for how colonies effectively distribute their foragers across available resources.
