    Learning and Living Difference That Makes A Difference: Postmodern Theory & Multicultural Education

    Get PDF
    The application of postmodern theory to a transformative understanding of multiculturalism can make a difference. Multicentered culture, antiessentialist race consciousness, and political equity—aspects of a transformative multiculturalism put forward in 1996 by Newfield and Gordon—can be juxtaposed with elements of a postmodern theorization of society as a consumer-driven economy saturated with multiple mediated unstable, fragmented, and evolving discourses and cultural interaction. This theoretical construct can be illustrated with research data from college classrooms and specifically an analysis of the television show The X-Files. This analysis shows how a discussion of whiteness creates larger discussion of transformative multiculturalism in which difference makes a difference. Moreover, a postmodern transformative multiculturalism sees universities as ideological sites in the production and reproduction of hegemony

    Using Technology to Open Storytelling Doors

    In a University of Minnesota College of Liberal Arts online spotlight on teaching, I\u27m deemed to be The Open-Door Storyteller. The article notes: One of Jacobs\u27 goals is to teach his students media literacy—analyzing critically what they read, hear, and see—without reducing their enjoyment of the media. He encourages his students to learn how to tell their own stories as a way of influencing how the media in turn portrays them. Technology has been a key part of this process ever since I first stepped into the classroom as an instructor in my third year of graduate school, in 1995. I\u27ll still be using technology in the classroom when I retire, around 2035..

    Using Lower-Division Developmental Education Students as Teaching Assistants

    Get PDF
    There has been little research on the experiences of undergraduate teaching assistants, and this small body of information is usually tightly focused on traditional disciplinary concerns like sociology, psychology, and communications. Additionally, undergraduate teaching assistant research tends to focus on upper-division students. This article explores the benefits and drawbacks of using lower-division developmental education students as teaching assistants in developmental social science courses. Included are comments from students enrolled in a course staffed by a sophomore as the teaching assistant. Employing developmental education students as teaching assistants can be beneficial to instructors, students, and the teaching assistants themselves

    Rapid Measurement of Quantum Systems using Feedback Control

    Full text link
    We introduce a feedback control algorithm that increases the speed at which a measurement extracts information about a dd-dimensional system by a factor that scales as d2d^2. Generalizing this algorithm, we apply it to a register of nn qubits and show an improvement O(n). We derive analytical bounds on the benefit provided by the feedback and perform simulations that confirm that this speedup is achieved.Comment: 4 pages, 4 figures. V2: Minor correction

    Fibrational induction rules for initial algebras

    Get PDF
    This paper provides an induction rule that can be used to prove properties of data structures whose types are inductive, i.e., are carriers of initial algebras of functors. Our results are semantic in nature and are inspired by Hermida and Jacobs’ elegant algebraic formulation of induction for polynomial data types. Our contribution is to derive, under slightly different assumptions, an induction rule that is generic over all inductive types, polynomial or not. Our induction rule is generic over the kinds of properties to be proved as well: like Hermida and Jacobs, we work in a general fibrational setting and so can accommodate very general notions of properties on inductive types rather than just those of particular syntactic forms. We establish the correctness of our generic induction rule by reducing induction to iteration. We show how our rule can be instantiated to give induction rules for the data types of rose trees, finite hereditary sets, and hyperfunctions. The former lies outside the scope of Hermida and Jacobs’ work because it is not polynomial; as far as we are aware, no induction rules have been known to exist for the latter two in a general fibrational framework. Our instantiation for hyperfunctions underscores the value of working in the general fibrational setting since this data type cannot be interpreted as a set

    Helping Kindergarteners Make Sense of Numbers to 100

    Get PDF
    The authors share what was learned about kindergarteners\u27 abilities to make sense of numbers to 100 when one of the authors, Linda Jaslow, took over a kindergarten class from February through the end of the school year. Through examples of how she engaged her students in nine weeks of problem solving and discussions focused on making sense of the number system, we provide evidence that the children grew substantially in their ability to count and show understanding when counting by 10\u27s and using 10\u27s during problem solving. Suggestions for tasks to promote continued growth are also provided. Throughout this teaching experience, Mrs. Jaslow was reminded of the complexity of making sense of our number system, and this article showcases her instructional decision making that was based on inquiry into children\u27s thinking. By valuing children\u27s existing ideas, Mrs. Jaslow could use that thinking to help guide her instruction
