Developing Critical Communities for Critical Conversations in K-12 Classrooms
As marginalized identities are still largely denied representation in society and students from dominant groups lack sociocultural knowledge to live in a multicultural democracy, books are a powerful tool to address injustices. This article provides teacher candidates as well as practicing teachers with tools to address social justice topics in their classes by building critical communities to support critical conversations and subsequently using texts as tools for teaching in socially just ways. We offer a three part framework including 1) How teachers can begin to prepare to engage in critical conversations with students; 2) Laying out necessary steps for structuring classrooms to cultivate critical conversations; and 3) Illuminating how young adult and children’s literature can be leveraged to serve these broader goals. Our hope is to contribute actionable steps to educators who want to engage in critical conversations with their students by providing an entry point for critical teaching practices
Moving from Inaction to Action: Challenging Homo- and Transphobia in Middle School English Language Arts
What happens when teachers have opportunities to engage in LGBTQ-affirming practices but choose not to? In the following paper, the authors present a vignette from a middle school context and consider ways to challenge silences to support LGBTQ students in middle school English classrooms. The authors provide discussion and resources to help teachers engage in LGBTQ affirming practices with middle school students
Test of CPT Symmetry and Quantum Mechanics with Experimental data from CPLEAR
We use fits to recent published CPLEAR data on neutral kaon decays to
and to constrain the CPT--violation parameters
appearing in a formulation of the neutral kaon system as an open
quantum-mechanical system. The obtained upper limits of the CPT--violation
parameters are approaching the range suggested by certain ideas concerning
quantum gravity.Comment: 9 pages of uuencoded postscript (includes 3 figures
Contribution of CPLEAR to the physics of the neutral kaon system
We present the physics results of the CP-- and CPT--violation measurements performed by CPLEAR. CPLEAR has experimentally determined for the first time, the violation of T invariance and is able to disentangle all the CP-- and CPT--violating quantities from each other. This allows each of the CPT violating parameters to be determined with a precision of a few and, in particular, the mass and width equality between the \kn and \knb to be tested down to the level of GeV. Moreover, the precision of the CPLEAR measurements allows us to probe for the first time physics on a scale approaching the Planck mass
Experimental tests of CPT symmetry and quantum mechanics at CPLEAR
We review a phenomenological parametrization of an open quantum-mechanical formalism for CPT violation in the neutral kaon system, and constrain the parameters using fits to recent CPLEAR data.We review a phenomenological parametrization of an open quantum-mechanical formalism for CPT violation in the neutral kaon system, and constrain the parameters using fits to recent CPLEAR data
Measurement of the neutral kaon regeneration amplitude in carbon at momenta below 1 GeV/c
The neutral kaon regeneration amplitude in carbon at momenta between 250 and 750~MeV/ was determined by measuring the interference of inherent and coherently regenerated \PKS\ amplitudes. This interference appears in the rates of initially pure (tagged) \PKz\ and \PaKz\ decaying to \Pgpp\Pgpm\ after crossing a carbon absorber
