Investigations
of Differential Item Functioning: Comparisons among approaches, and Extension
to a Multidimensional context Dr Insu Paek, UC Berkeley Differential item functioning (DIF) has been one of the major topics in the measurement field for the last thirty years. In this study, a unidimensional parametric item response theory (IRT) DIF method based on multidimensional random coefficient multinomial logit (MRCML) model (Adams, Wilson, & Wang, 1997) and Mooreís (1996) work is formulated, and its performance is compared with the simultaneous bias test (SIBTEST) model (Shealy and Stout, 1993) by simulation studies. SIBTEST is a non-parametric IRT DIF model. These two approaches are compared in a variety of simulated conditions.Ý The foci of the comparisons are the behavior of DIF estimators, Type I error and Power. For the Type I error and power investigation, (asymptotic) z-test and likelihood ratio test are used in the suggested parametric method. Lastly, Using the flexibility of the MRCML model, a multidimensional extension of the unidimensional parametric DIF modeling is attempted and its performance is investigated by a simulation study. The effect of using a unidimensional DIF model in a multidimensional test on the DIF investigation is also shown by simulation study. |

Linear Regression: Dr. Sophia Rabe-Hesketh, Linear regression will
be introduced by considering the problem of assessing and comparing schools'
effectiveness. Starting with a t-test, proceeding to simple and multiple
linear regression, I will finish with a brief
introduction to multilevel modeling. Emphasis will be on interpretation
rather than technical details.

From Authentic Assessment to Authentic Accountability: A
View of Lateral Accountability in Education Prof Current approaches to
educational accountability privilege hierarchical forms of thought in which
the blame game races up and down systems with little evidence of improvement
of performance at hand. This talk will propose and examine an alternative to
current hierarchical models of educational accountability, one in which
accountability is approached as a constructivist undertaking in its own
right.Ý The approach values lateral
forms of accountability, in which each element of the system is directly
accountable to the various publics that it serves.Ý Relevant research on human motivation will
be brought to bear to inform an accountability policy and approach that
genuinely seeks to motivate increased effort and improved performance.Ý In addition the conditions (e.g.,
intellectual, dispositional, structural, etc.) necessary to engender this
approach to accountability will be explored. Finally, a survey of extensive
research on and experience with accountability systems will suggest defining
issues that shape the debate about accountability policy and practice. |

The Diversity in Math Education Project
Encounters the Real World Prof Alan H. Schoenfeld,
UC Berkeley With the arrival of the new superintendent of the
Berkeley Unified School District (BUSD), Michele Lawrence, a simple plan for
having a "teacher in residence" at UCB expanded into a major
collaboration between BUSD and the "Diversity in Mathematics
Education" (DiME) center at UCB.Ý There is now an ongoing seminar with middle
school teachers, focusing on issues of diversity and middle school
mathematics. DiME is grappling with these issues,
among others: * Whether and how to evaluate the piloting of
curricular materials, where teacher assignments aren't random and the
curricula aren't equivalent; * How to capture what students learn, in fine-grained
detail, as part of "lesson study"; * What data to gather to document in order to capture
equity-related phenomena, and chart whether the district is making progress; * How to measure the impact of professional
development. Life isn't easy in the real world.Ý We will describe how the project evolved
and some of the issues involved in trying to make a difference through
careful research in settings that won't sit still. |
