The DEBS 2020 grand challenge

The ACM DEBS 2020 Grand Challenge is the tenth in a series of challenges which seek to provide a common ground and evaluation criteria for a competition aimed at both research and industrial event-based systems. The focus of the ACM DEBS 2020 Grand Challenge is on Non-Intrusive Load Monitoring (NILM). The goal of the challenge is to detect when appliances contributing to an aggregated stream of voltage and current readings from a smart meter are switched on or off. NILM is leveraged in many contexts, ranging from monitoring of energy consumption to home automation. This paper describes the specifics of the data streams provided in the challenge, as well as the benchmarking platform that supports the testing of the solutions submitted by the participants

Making Sense of Montessori Teacher Identity, Montessori Pedagogy, and Educational Policies in Public Schools

Montessori teachers in public schools navigate a system daily that often does not align with their pedagogy, and district policies push them to stray from high-fidelity implementation. Using Weick’s sensemaking theory and literature on Montessori teacher identity, I contend that Montessori teachers’ identity plays a crucial role in how, or if, they respond to educational policies that may not seemingly align with the Montessori Method. The overarching purpose of this study was to understand Montessori public school teachers’ experiences with policies that influence their pedagogy. Through qualitative interviews and a culminating group-level assessment session, three themes emerged as teachers shared their experiences with educational policies: (a) Montessori pedagogy is more than the materials, (b) districts often force district-wide requirements that are at odds with the Montessori pedagogy, and (c) Montessori teachers in public schools do not feel supported. This article concludes with a discussion of how to better support Montessori teachers in public school settings based on the study’s findings
