    Conditions for building a community of practice in an advanced physics laboratory

    Get PDF
    In this paper we explore the theory of communities of practice in the context of a physics college course and in particular the classroom environment of an advanced laboratory. We introduce the idea of elements of a classroom community being able to provide students with the opportunity to have an accelerated trajectory towards being a more central participant of the community of practice of physicists. This opportunity is a result of structural features of the course and a primary instructional choice which result in the development of a learning community with several elements that encourage students to engage in more authentic practices of a physicist. A jump in accountable disciplinary knowledge is also explored as a motivation for enculturation into the community of practice of physicists. In the advanced laboratory what students are being assessed on as counting as physics is significantly different and so they need to assimilate in order to succeed.Comment: 14 pages, 1 figur

    Neurohumoral and mechanical factors in the modulation of left ventricular mass

    The goals for the research were to define, describe, and study those neuroendocrine and mechanical mechanisms that may play a role in the initiation and maintenance of an increase in, or cause regression of, the mass of the left ventricle. Dynamic changes in heart mass have been observed to occur in man and animals: (1) enlargement of the heart is frequently encountered in patients with hypertensive disease, and (2) decrease in heart mass has been reported for men exposed to prolonged space flight. The basic physiologic processes which may explain how these changes occur, and the effects of gain or loss of myocardial mass on cardiac performance were considered significant questions to be answered for the benefit of the National Aeronautics and Space Administration

    Fluctuations in Student Understanding of Newton's 3rd Law

    We present data from a between-student study on student response to questions on Newton's Third Law given throughout the academic year. The study, conducted at Rochester Institute of Technology, involved students from the first and third of a three-quarter sequence. Construction of a response curve reveals subtle dynamics in student learning not captured by simple pre/post testing. We find a a significant positive effect from direct instruction, peaking at the end of instruction on forces, that diminishes by the end of the quarter. Two quarters later, in physics III, a significant dip in correct response occurs when instruction changes from the vector quantities of electric forces and fields to the scalar quantity of electric potential. Student response rebounds to its initial values, however, once instruction returns to the vector-based topics involving magnetic fields.Comment: Proceedings of the 2010 Physics Education Research Conferenc

    Steady and unsteady transonic pressure measurements on a clipped delta wing for pitching and control-surface oscillations

    Get PDF
    Steady and unsteady pressures were measured on a clipped delta wing with a 6-percent circular-arc airfoil section and a leading-edge sweep angle of 50.40 deg. The model was oscillated in pitch and had an oscillating trailing-edge control surface. Measurements were concentrated over a Mach number range from 0.88 to 0.94; less extensive measurements were made at Mach numbers of 0.40, 0.96, and 1.12. The Reynolds number based on mean chord was approximately 10 x 10 to the 6th power. The interaction of wing or control-surface deflection with the formation of shock waves and with a leading-edge vortex generated complex pressure distributions that were sensitive to frequency and to small changes in Mach number at transonic speeds

    The use of family conferences at the psychiatric clinic of the Children's Medical Center

    Full text link
    Thesis (M.S.)--Boston UniversityThis is a study of 1) the ways in which family conferences are used in the Psychiatric Clinic of the Children's Medical Center; 2) the social worker's feelings and attitudes about these conferences; 3) team relationships in these conferences; and 4) implications of the family conference for the casework relationship. In order to describe the conferences and explore the social worker's feelings and attitudes, information was sought in six general areas: 1) how the conferences were used by the clinic and therapists; 2) social worker's general knowledge and experience with family conferences; 3) factors in team relationships; 4) the client's reactions to the family conference; 5) implications of the family conferences for the casework relationship, and 6) the social worker's evaluation of family conferences in general
