Professional development to support principals' vision of science instruction: Building from their prior experiences to support the science practices

The implementation of science reform must be viewed as a systems-level problem and not just focus on resources for teachers and students. High-capacity instructional leadership is essential for supporting classroom science instruction. Recent reform efforts include a shift from learning about science facts to figuring out scientific phenomena in which students use science practices as they build and apply disciplinary core ideas. We report findings from a research study on professional development (PD) to support instructional leaders' learning about the science practices. After participating in the PD, the instructional leaders' familiarity with and leadership content knowledge of the science practices significantly improved. Initially, principals used their understandings from other disciplines and content neutral visions of classrooms to make sense of science instruction. For example, they initially used their understandings of models and argument from ELA and math to make sense of science classroom instruction. Furthermore, some principals focused on content neutral strategies, like a clear objective. Over the course of the PD workshops, principals took up the language of the science practices in more nuanced and sophisticated ways. Principals' use of the language of the science practices became more frequent and shifted from identifying or defining them to considering quality and implementation in science classrooms. As we design tools to support science, we need to consider instructional leaders as important stakeholders and develop resources to specifically meet their needs. If the science feels too unfamiliar or intimidating, principals may avoid or reframe science reform efforts. Consequently, it is important to leverage instructional leaders' resources from other disciplines and content neutral strategies as bridges for building understanding in science. We argue that the science practices are one potential lever to engage in this work and shift instructional leaders' understandings of science instruction.

Preschoolers rely on rich speech representations to process variable speech

To learn language, children must map variable input to categories such as phones and words. How do children process variation and distinguish between variable pronunciations (“shoup” for soup) versus new words? The unique sensory experience of children with cochlear implants, who learn speech through their device's degraded signal, lends new insight into this question. In a mispronunciation sensitivity eyetracking task, children with implants (N = 33), and typical hearing (N = 24; 36–66 months; 36F, 19M; all non-Hispanic white), with larger vocabularies processed known words faster. But children with implants were less sensitive to mispronunciations than typical hearing controls. Thus, children of all hearing experiences use lexical knowledge to process familiar words but require detailed speech representations to process variable speech in real time.     

A combined microfluidic-microstencil method for patterning biomolecules and cells

Despite the myriad of soft lithography based micropatterning methods available to researchers, it is still challenging to define small features (10–100 μm) that are spaced far apart (1–10 mm). In this report, we describe a combined microfluidic-microstencil patterning method that can produce multifunctional substrates of small features, O(10 μm), with a large pitch, O(1 mm). In that, we fabricate microstencils using an UV curable polyurethane (Norland Optical Adhesive 81) with dense arrays of 10–100 μm holes. Overlaying arrays of microfluidic channels over these microstencils allow for the control of the spacing between features and the ability to pattern multiple substrates. We show that this method is capable of patterning soluble proteins, fibrillar insoluble collagen, liposomes, cells, and nanoparticles. We demonstrate the utility of the method by measuring platelet adhesion under flow to three adhesive proteins (insoluble fibrillar collagen, laminin, and reconstituted acid solubilized collagen fibers) in a single assay.     

Writing the Self: Wittgenstein,Confession and Pedagogy

In this paper I investigate ‘the confessional’ as an aspect of Wittgenstein's style both as a mode of philosophising and as a mode of ‘writing the self’, tied explicitly to pedagogical practices. There are strong links between Wittgenstein's confessional mode of philosophising and his life—for him philosophy is a way of life —and interesting theoretical connections between confessional practices and pedagogy, usefully explored in the writings of the French philosopher, Michel Foucault. The Investigations provides a basis and springboard for understanding the notion of ‘writing the self’ as a pedagogical practice which encourages a confessional mode compelling us to tell the truth about ourselves and, thus, creating the conditions for ethico‐poetical self‐constitution.     

Transcending and Attending to Difference in the Multicultural Classroom

In this paper, I hope to reconcile two conflicting moral ideals within the multicultural classroom. I argue that increased attention to cultural difference in both education and moral philosophy is vitally important, but that it should not undermine the value of generalised respect, which grounds formal equality. I argue that an intersubjective account of respect explicitly integrates the generalised and particular moral perspectives, and thus serves as an ideal for interactions in the multicultural classroom. Through the analysis of two examples, I show that both forms of respect are logically dependent on one another and have a mutually supportive place in the practice of teaching.
