Sustaining Educational Reforms in Introductory Physics

While it is well known which curricular practices can improve student performance on measures of conceptual understanding, the sustaining of these practices and the role of faculty members in implementing these practices are less well understood. We present a study of the hand-off of Tutorials in Introductory Physics from initial adopters to other instructors at the University of Colorado, including traditional faculty not involved in physics education research. The study examines the impact of implementation of Tutorials on student conceptual learning across eight first-semester, and seven second-semester courses, for fifteen faculty over twelve semesters, and includes roughly 4000 students. It is possible to demonstrate consistently high, and statistically indistinguishable, student learning gains for different faculty members; however, such results are not the norm, and appear to rely on a variety of factors. Student performance varies by faculty background - faculty involved in, or informed by physics education research, consistently post higher student learning gains than less-informed faculty. Student performance in these courses also varies by curricula used - all semesters in which the research-based Tutorials and Learning Assistants are used have higher student learning gains than those semesters that rely on non-research based materials and do not employ Learning Assistants.Comment: 21 pages, 4 figures, and other essential inf

European clinical guidelines for Tourette syndrome and other tic disorders. Part II: pharmacological treatment

To develop a European guideline on pharmacologic treatment of Tourette syndrome (TS) the available literature was thoroughly screened and extensively discussed by a working group of the European Society for the Study of Tourette syndrome (ESSTS). Although there are many more studies on pharmacotherapy of TS than on behavioral treatment options, only a limited number of studies meets rigorous quality criteria. Therefore, we have devised a two-stage approach. First, we present the highest level of evidence by reporting the findings of existing Cochrane reviews in this field. Subsequently, we provide the first comprehensive overview of all reports on pharmacological treatment options for TS through a MEDLINE, PubMed, and EMBASE search for all studies that document the effect of pharmacological treatment of TS and other tic disorders between 1970 and November 2010. We present a summary of the current consensus on pharmacological treatment options for TS in Europe to guide the clinician in daily practice. This summary is, however, rather a status quo of a clinically helpful but merely low evidence guideline, mainly driven by expert experience and opinion, since rigorous experimental studies are scarce

The Institutional Case for Partisan Gerrymandering Claims

For voters hoping the Supreme Court’s 2017 Term brings relief from partisan gerrymandering, the end of the 2016 Term was inauspicious. In Cooper v. Harris, the majority assumed the legitimacy of “partisan advantage” arguments while the dissent—including Justice Kennedy—warned about the “serious institutional and federalism implications” of judicial intervention in the redistricting process. If past is prologue, this concern for institutional and structural interests does not bode well

GIS, critique, representation and beyond

Geographical information systems (GIS) have been a part of archaeological research practices for over two decades, yet many significant questions related to the technology remain unanswered. Long-standing ambiguities about GIS use in archaeology can be associated with a particular research atmosphere within the discipline, where a large number of practitioners consider theory-laden critical approaches to GIS optional, if not peripheral, to conducting spatial analysis. This article calls on archaeological GIS practitioners to carry existing GIS theory and critique to another level. It also argues that the critique of the epistemological implications of GIS use in archaeology has largely (and at times rather implicitly) been structured by representational thinking habits and that a move to non-representational thinking would provide novel considerations of the technology. © The Author(s) 2012
