This study examines the influence of a year-long mathematics professional development program on Kindergarten teachers’ beliefs, content knowledge, instructional practices, and their students’ achievement. The professional development program is grounded in the theoretical construct of learner-centered professional development and focuses on supporting teachers’ integration of standards-based pedagogies aligned with the Common Core State Standards in Mathematics. Data analysis included examining 15 Kindergarten teachers’ mathematics content knowledge, their beliefs about mathematics, their enactment of student-centered pedagogies, and student achievement on curriculum-based assessments. Findings indicated that teachers adopted more student-centered pedagogies and embraced more student-centered beliefs about mathematics teaching during their time in the project. Further, Kindergarten teachers also demonstrated gains in their mathematical content knowledge, and those content knowledge gains were linked to gains in student achievement.  相似文献

Identifying future scientists: predicting persistence into research training     

McGee R  Keller JL 《CBE life sciences education》2007,6(4):316-331

This study used semistructured interviews and grounded theory to look for characteristics among college undergraduates that predicted persistence into Ph.D. and M.D./Ph.D. training. Participants in the summer undergraduate and postbaccalaureate research programs at the Mayo Clinic College of Medicine were interviewed at the start, near the end, and 8–12 months after their research experience. Of more than 200 themes considered, five characteristics predicted those students who went on to Ph.D. and M.D./Ph.D. training or to M.D. training intending to do research: 1) Curiosity to discover the unknown, 2) Enjoyment of problem solving, 3) A high level of independence, 4) The desire to help others indirectly through research, and 5) A flexible, minimally structured approach to the future. Web-based surveys with different students confirmed the high frequency of curiosity and/or problem solving as the primary reason students planned research careers. No evidence was found for differences among men, women, and minority and nonminority students. Although these results seem logical compared with successful scientists, their constancy, predictive capabilities, and sharp contrast to students who chose clinical medicine were striking. These results provide important insights into selection and motivation of potential biomedical scientists and the early experiences that will motivate them toward research careers.  相似文献

IMPACT OF EXPLICIT PRESENTATION OF SLOPES IN THREE DIMENSIONS ON STUDENTS’ UNDERSTANDING OF DERIVATIVES IN MULTIVARIABLE CALCULUS     

McGee  Daniel Lee  Moore-Russo  Deborah 《International Journal of Science and Mathematics Education》2014,13(2):357-384

In two dimensions (2D), representations associated with slopes are seen in numerous forms before representations associated with derivatives are presented. These include the slope between two points and the constant slope of a linear function of a single variable. In almost all multivariable calculus textbooks, however, the first discussion of slopes in three dimensions (3D) is seen with the introduction of partial derivatives. The nature of the discussions indicates that authors seem to assume that students are able to naturally extend the concept of a 2D slope to 3D and correspondingly it is not necessary to explicitly present slopes in 3D. This article presents results comparing students that do not explicitly discuss slopes in 3D with students that explicitly discuss slopes in 3D as a precursor to discussing derivatives in 3D. The results indicate that students may, in fact, have significant difficulty extending the concept of a 2D slope to a 3D slope. And that the explicit presentation of slopes in 3D as a precursor to the presentation of derivatives in 3D may significantly improve student comprehension of topics of differentiation in multivariable calculus.

Beyond Punnett Squares: Student Word Association and Explanations of Phenotypic Variation through an Integrative Quantitative Genetics Unit Investigating Anthocyanin Inheritance and Expression in Brassica rapa Fast Plants

Genetics instruction in introductory biology is often confined to Mendelian genetics and avoids the complexities of variation in quantitative traits. Given the driving question “What determines variation in phenotype (Pv)? (Pv=Genotypic variation Gv + environmental variation Ev),” we developed a 4-wk unit for an inquiry-based laboratory course focused on the inheritance and expression of a quantitative trait in varying environments. We utilized Brassica rapa Fast Plants as a model organism to study variation in the phenotype anthocyanin pigment intensity. As an initial curriculum assessment, we used free word association to examine students’ cognitive structures before and after the unit and explanations in students’ final research posters with particular focus on variation (Pv = Gv + Ev). Comparison of pre- and postunit word frequency revealed a shift in words and a pattern of co-occurring concepts indicative of change in cognitive structure, with particular focus on “variation” as a proposed threshold concept and primary goal for students’ explanations. Given review of 53 posters, we found ∼50% of students capable of intermediate to high-level explanations combining both Gv and Ev influence on expression of anthocyanin intensity (Pv). While far from “plug and play,” this conceptually rich, inquiry-based unit holds promise for effective integration of quantitative and Mendelian genetics.  相似文献

Historicizing Mathematics and Mathematizing Social Studies for Social Justice: A Call for Integration     

Ebony O. McGee  Andrew L. Hostetler 《Equity & Excellence in Education》2013,46(2):208-229

Researchers and theorists in education have offered persuasive arguments and evidence documenting the need for, and benefits of, education for social justice. Despite these efforts the intersection of social justice with interdisciplinary curricular designs remains underexplored. This article argues that social justice education is enriched through interdisciplinary curricula, in that it holds the potential for students to develop deeper conceptions of social justice and experience deeper learning outcomes related to content knowledge across subject matter areas. Central to this argument is the notion that situating disciplinary relationships explicitly within social justice perspectives encourages an emphasis on broader and richer sociopolitical consciousness among learners. We draw on historical and contemporary narratives to position social justice in mathematics and social studies education. As researchers in these two fields, we envision greater possibilities for the advancement of knowledge, and we envision learning from inequalities and resisting oppression by nurturing deeper, more explicit connections between mathematics and social studies. We conclude this article with three overviews of learning segments as potential representations of interdisciplinary mathematics-social studies for social justice work in secondary school contexts.  相似文献   

Building a whole school approach and teacher efficacy with English language learners     

Penny Haworth  Alyson McGee  Lesieli Kupu MacIntyre 《Teachers and Teaching》2013,19(2):164-177

Current professional development initiatives show a preference for whole school approaches. However, pedagogy related to English language learners (ELLs) is often not widely dispersed in New Zealand primary schools, impacting on teacher efficacy with these learners. This paper discusses findings from a qualitative study which aimed to identify influences shaping the dispersal of ELL-related pedagogy in two schools in contrasting socio-economic areas. Data from semi-structured individual interviews with teachers at different class levels revealed unique patterns for the dispersal of ELL-related pedagogy in each school. Teacher data indicated that these patterns were influenced by the performance of ELLs in national standards testing, as well as the special characteristics of ELLs in each setting and the distinctive nature of each context. The dispersal of ELL pedagogy in each school impacted differentially on opportunities to build a sense of collective teaching efficacy with ELLs in that setting, but also raised questions about whether one size should be expected to fit all.  相似文献   

Dual Pathways to Expression and Understanding: Canadian Coming-of-Age Graphic Novels     

Janette Hughes  Alyson E. King 《Children‘s Literature in Education》2010,41(1):64-84

In this article, the authors examine three Canadian coming-of-age stories, written as graphic novels, and pay particular attention to how the images and print text come together in the telling of the narrative. This approach reinforces the notion that form and content cannot be separated in this medium. Drawing on examples from each of the graphic novels and the interviews with the graphic novelists who wrote them, the article explores the complexity of the coming-of-age theme in each graphic novel, as well as how print text and image converge to make meaning.  相似文献
