Students' Early Mathematical Representation Knowledge: The Effects of Emphasizing Single or Multiple Perspectives of the Rational Number Domain in Problem Solving     

Bryan?MoseleyEmail author 《Educational Studies in Mathematics》2005,60(1):37-69

This study examined changes in 26 fourth-grade students' early conceptions of rational number representations as a function of receiving one of two curricular interventions. The first group of 12 students received a curriculum that emphasized constructing knowledge through extended problem solving with a single perspective of the rational number domain based on part-whole relations. A second group of 14 students received a curriculum that emphasized a more conceptually diverse multiple perspective view of the domain through problem solving with operator and ratio relations. Analyses of the students' rational number knowledge before and after the interventions indicated that students in the single perspective group produced organizations of knowledge that more frequently diverged from a formal domain analysis than those produced by students in the multiple perspective group. Further, students in the single perspective group increased their focus on superficial surface features. Alternatively, students in the multiple perspective group demonstrated an increased focus on operations that more frequently reflected the underlying mathematical relation conveyed by the representation. The findings indicate that an early exposure to more diverse perspectives of rational numbers assists students in developing more interconnected and viable representation knowledge for rational numbers.  相似文献   

Professional development for university scientists around issues of equity and diversity: Investigating dissent within community     

Julie A. Bianchini  Bryan A. Hilton‐Brown  Therese D. Breton 《科学教学研究杂志》2002,39(8):738-771

We investigated the role of dissent in a community of university scientists, engineers, mathematicians, and social scientists engaged in a 2‐year professional development project around issues of equity and diversity. Members of this teacher learning community explored issues related to gender and ethnicity in science education, and attempted to develop course materials and instructional strategies inclusive of students from underrepresented groups. We focused our attention on those professional development sessions (6 of the 19) devoted to a contentious yet integral topic in science education: the gendered and multicultural nature of science. We examined conversations initiated by a member's concerns to learn how dissent led (or failed to lead) to new insights into feminist science studies scholarship or to greater understanding of ways to address equity issues in undergraduate science education. We also explored how teacher learners' resulting views of feminist science studies scholarship informed (or failed to inform) changes in their own educational practices. From our qualitative analyses, we highlight the challenges in balancing respect for members' individual voices with collective progress toward project goals, and in structuring conversations initiated by dissent to provide adequate space for deliberation and movement toward deeper understanding of equity and excellence. © 2002 Wiley Periodicals, Inc.

Nestedness of beliefs: Examining a prospective elementary teacher's belief system about science teaching and learning     

Lynn A. Bryan 《科学教学研究杂志》2003,40(9):835-868

This study, conducted from a constructivist perspective, examined the belief system of a prospective elementary teacher (Barbara) about science teaching and learning as she developed professional knowledge within the context of reflective science teacher education. From an analysis of interviews, observation, and written documents, I constructed a profile of Barbara's beliefs that consisted of three foundational and three dualistic beliefs. Her foundational beliefs concerned (a) the value of science and science teaching, (b) the nature of scientific concepts and goals of science instruction, and (c) control in the science classroom. Barbara held dualistic beliefs about (a) how children learn science, (b) the science students' role, and (c) the science teacher's role. Her dualistic beliefs formed two contradictory nests of beliefs. One nest, grounded in lifelong science learner experiences, reflected a didactic teaching orientation and predominantly guided her practice. The second nest, not well grounded in experience, embraced a hands‐on approach and predominantly guided her vision of practice. The findings accentuate the complexity and nestedness of teachers' belief systems and underscore the significance of identifying prospective teachers' beliefs, espoused and enacted, for designing teacher preparation programs. © 2003 Wiley Periodicals, Inc.

Attitudes toward science and science knowledge of intellectually gifted and average students in third,seventh, and eleventh grades     

Byron L. Barrington  Bryan Hendricks 《科学教学研究杂志》1988,25(8):679-687

A questionnaire regarding attitudes toward science and scientific knowledge (Yager & Yager, 1985b) was administered to 143 intellectually gifted (IQ > 130) and intellectually average third-, seventh-, and eleventh-grade students. Measures of internal reliability on four attitude subscales and a content knowledge subscale are reported. Three-way ANOVAs comparing grade, sex, and ability revealed significant differences between average and gifted students in attitudes toward being a scientist, usefulness of science, and, as might be expected, in knowledge of science. Similarly, there were significant differences between grades on attitudes toward teachers and toward science classes, with the most favorable attitudes expressed in third grade, next most favorable in eleventh grade, and clearly more negative attitudes expressed by students in seventh grade. There also was a significant interaction between grade level and ability regarding attitudes toward science classes. In contrast to what might be expected from reported differences between males and females in attitudes toward science, gender as a separate variable did not have a significant main effect in any of the comparisons.  相似文献

Terminus Amnesia: Cherokee Freedmen,Citizenship, and Education     

Jeremiah Chin  Nicholas Bustamante  Jessica Ann Solyom  Bryan McKinley Jones Brayboy 《理论付诸实践》2016,55(1):28-38

In 2007, the Cherokee Nation of Oklahoma amended its constitution to limit membership to only those who can trace lineal descent to an individual listed as Cherokee by Blood on the final Dawes Rolls. This exercise of sovereignty paradoxically ties the Dawes Rolls, the colonial instruments used to divide the lands and peoples of the Cherokee Nation, and self-determination. In the process, it effectively disenrolls Cherokee Freedmen, the descendants of Blacks enslaved by the Cherokee Nation. In this article, we explore the implications of this history in the context of self-determination and sovereignty, particularly looking at the influence of colorism on the Dawes Rolls and its ongoing effects. Our goal is to share a piece of history that is often obscured or unknown; to explore how and to what extent the exercise of self-determination and sovereignty in Indigenous nations is impacted by colorism; and finally to consider implications for practice created by the disenfranchisement of peoples from Indigenous nations.  相似文献   

Classifying the Evidence Base of Classwide Peer Tutoring for Students with High-Incidence Disabilities     

Sara Cothren Cook  Bryan G. Cook  Lysandra Cook 《Exceptionality》2017,25(1):9-25

Evidence-based reforms that emphasize the identification and implementation of empirically validated practices are at the forefront of educational research, and recently, the Council for Exceptional Children (CEC; 2014) published a set of standards for establishing evidence-based practices in special education. Although 30 years of research supports the effectiveness of ClassWide Peer Tutoring (CWPT), an instructional strategy intended to increase engagement and improve academic outcomes for students with disabilities, a formal evidence-based review has not yet been conducted on the practice. The purpose of this study is to examine whether CWPT, as developed by the Juniper Gardens Children’s Project at the University of Kansas, can be considered an evidence-based practice for academic outcomes of students with high incidence disabilities using the CEC standards. Sixteen single-case design studies met inclusion criteria; no studies addressed all the required quality indicators. Although results of multiple studies show that CWPT had positive effects, the lack of methodologically sound studies supporting the practice means that CWPT is not considered an evidence-based practice according to the CEC (2014) standards. Implications for research and practice are discussed.  相似文献   

Communication competence in reading and learning disabilities     

Tanis H. Bryan 《Annals of dyslexia》1979,29(1):172-188

Conclusion The evidence indicates that learning-disabled children show pervasive and enduring language problems across a wide variety of language tasks. The studies suggest that the problems experienced by learning and reading-disabled children may fall into the categories of phonology, syntax, semantics, and pragmatics as well as nonverbal communication. In terms of nonverbal communication, these children are less accurate in interpreting nonverbal auditory and visual cues. In phonology, it appears that they are less skilled in detecting the segments of single words and thus have difficulty establishing phoneme to grapheme correspondence. In the area of syntax, learning-disabled males are less skilled in dealing with inflection and the comprehension and creation of complex sentences. In semantics, they are less adequate than nondisabled children in defining words, creating sentences, and classifying objects into categories. They show less adequate sentence production, are less skilled at recognizing their errors, and are significantly slower in generating verbal responses. Finally, there is one study that suggests that learning-disabled children may be discriminated by their use of language in social situations. This paper was presented at the 29th Annual Conference of The Orton Society at Minneapolis, November, 1978.  相似文献
