Many formal policies have suggested that officers need a college degree; however, policies forced little change in practices of American police organizations. Six hundred-fifty patrol officers employed in 12 medium-sized police departments in three Midwestern states were surveyed as to their current educational attainment and job performance. The purpose of this study was to determine the relationship between educational level and police performance.  相似文献

Implementing curriculum that is inclusive of lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ) people has the potential to create an equitable learning environment. In order to learn more about students’ experiences of LGBTQ-inclusive curriculum, 26 high school students with diverse racial/ethnic, sexual, and gender identities were recruited from the Gay Straight Alliance (GSA) Network in California. Students participated in focus groups conducted by telephone by GSA staff, sharing their experiences of LGBTQ-inclusive curriculum in school. Qualitative coding methods, including grounded theory, were used to identify themes and interpret students’ responses. Data revealed that LGBTQ-inclusive curriculum was most often taught in social sciences and humanities courses as stand-alone lessons. LGBTQ-inclusive curriculum rarely met standards of social justice education, though opportunities for critical conversations about systemic oppression regularly emerged. For instance, teachers often failed to intervene in LGBTQ bullying and missed teachable moments conducive to inclusive curriculum. Some students learned positive LGBTQ lessons and highlighted the ways such curriculum reflected their identities and created a supportive school climate. Implications for equitable education are discussed.  相似文献

Superintendents from districts in the Minority Student Achievement Network (MSAN) challenged the Strategic Education Research Partnership (SERP) to identify an approach to narrowing the minority student achievement gap in Algebra 1 without isolating minority students for intervention. SERP partnered with 8 MSAN districts and researchers from 3 universities to design and rigorously test AlgebraByExample, a set of 42 Algebra 1 assignments with interleaved worked examples that target common misconceptions and errors. In a year-long random-assignment study, students who received AlgebraByExample assignments had an average 7 percentage point boost on a posttest containing released items from state assessments, and students in the bottom half of the performance distribution where minority students are disproportionately concentrated had an average 10 percentage point boost on a researcher-designed assessment of conceptual understanding. AlgebraByExample is easily incorporated into any existing curriculum, and naturally serves as a launch point for mathematically rich discussion.  相似文献

This article explores the intersection of new, large-scale standards-based testing, teacher accountability policy, and secondary curriculum and instruction in the United States. Two federally funded consortia – the Smarter Balanced Assessment Consortium and the Partnership for Readiness of College and Careers – prove focal to this paper, as these two organisations are creating new tests that will assess 42–49% of the K–12 student population in the United States in 2014–2015. Because greater teacher accountability for student performance will be given for these tests, there is more reason to pay attention to what these tests measure and what they do not. Our analysis suggests that these new tests will hold secondary English teachers accountable for literacy and disciplinary knowledge outside the field of English and thus raise important questions about what English teachers should, can and will do, especially when their jobs are on the line.  相似文献
