Defining Early Number Sense: A participatory Australian study     

Sally Howell  Coral Kemp 《教育心理学》2005,25(5):555-571

Recent publications in Australia focus on “number sense” as an important component of mathematics instruction. The current study attempted to tap into local expert knowledge in the area of early mathematics in an effort to establish a consensus on which skills reflect the number sense typically acquired by school entry. A modified Delphi procedure was employed whereby participants were asked to indicate their level of agreement with a variety of skills as indicators of number sense in young children. The study raised questions about the efficacy of this type of participatory research when used in relation to an ill‐defined construct. It also revealed a lack of consensus among the group of academics who agreed to participate in the study.  相似文献   

Making connections: the logical structuring of hypertext documents     

Patrik O'Brian Holt  Gordon Howell 《Instructional Science》1992,21(1-3):169-181

The results from an experiment analysing hypertextual semantic linking is reported. In the study participants are asked to describe logical relationships between related, semi-related and unrelated paragraphs of text. It is concluded that existence and themes of relationships are (as expected) fairly consistently recognised, however, specific relationships do not readily fall into natural predicate like statements. Purely thematic relationships, or a palette of available relationships might be the more practical approach. Further work on dynamic linking in hypertext documents is also reported. Dynamic linking eliminates some of the problems associated with a mismatch between the mental models of authors and readers and allows the readers to construct their own hypertexts from linear documents. This approach offers useful data on logical connectivity in hypertext documents but also represents an alternative to conventional hypertext authoring and reading.  相似文献   

The Efficacy of Policy Statements on Plagiarism: Do They Change Students' Views?   总被引：3，自引：0，他引：3  

Brown  Verity J.  Howell  Mark E. 《Research in higher education》2001,42(1):103-118

Concern about academic dishonesty has led to studies designed to explore its nature, prevalence, and causes. Nevertheless, to date there has been little empirical work designed to test the efficacy of measures to reduce cheating behavior. Many authors agree that there should be institutional statements about academic dishonesty that give definitions and state the penalties for cheating. The purpose of this study was to examine the efficacy of such statements in terms of their influence on perceived severity and perceived incidence of plagiarism in undergraduates. We found that having the students read a carefully worded statement about plagiarism was an effective way to change the perceptions of how seriously plagiarism breaches academic guidelines. Our data further suggest that providing guidance about avoiding plagiarism that encourages students to take a more serious view of the issue is likely to have positive effects on future behavior.  相似文献   

Associations between Profiles of Maternal Strengths and Positive Parenting Practices among Mothers Experiencing Adversity     

Kristina M. Decker  Idia B. Thurston  Kathryn H. Howell  Amanda J. Hasselle  Rebecca C. Kamody 《Parenting, science and practice》2021,21(1):1-23

SYNOPSIS

Objective . Few studies have explored associations between strength-based factors and positive parenting among mothers experiencing adversity. Adopting a person-centered statistical approach, we examined how patterns of maternal strengths relate to positive parenting practices. Design . Participants were 188 female primary caregivers (71% African American) who experienced intimate partner violence and/or were living with HIV. Women were recruited from community organizations in the Mid-Southern United States and completed measures of adaptability, spirituality, ethnic identity, social support, parent-child communication, community cohesion, and parenting practices. Latent profile analysis was used to generate classes of individual (adaptability, spirituality, education), relational (family support, friend support, parent-child communication about Substance Abuse, Violence, and AIDS/HIV), and contextual (ethnic identity, community cohesion) factors, in line with the social-ecological model of resilience. Associations between the classes and positive parenting practices were examined. Results . Three classes emerged: (1) Low Individual, Relational, & Contextual (LIRC; n = 18); (2) Low SAVA Communication (LSC; n = 30); and (3) High Individual, Relational, & Contextual (HIRC; n = 140). Mothers in the LIRC class reported lower parental involvement and less positive parenting practices than those in the HIRC class. Conclusions . Mothers who endorse increased individual, relational, and contextual factors utilize more positive parenting practices. Optimal clinical approaches to enhance parenting should target supports at multiple levels.  相似文献

Entropic Management: Restructuring District Office Culture in the New York City Department of Education     

Fanon John Howell 《The Urban Review》2014,46(4):725-746

Although a growing body of literature is produced on reform of urban school districts, few studies examine shifts in the culture of managers resulting from reorganization in these bureaucracies. This article engages an analysis of central office managerial culture in the New York City Department of Education during a culminating moment of district office restructuring. I argue that a lack of consistent practices ensuring inter-office network building was instrumental in shifting the prevailing culture of the central office from an instruction-based to an accountability-based organization. Managerial restructuring was coordinated by way of empowerment, technology, and the use of space. I label this arrangement entropic, arguing an order through disorder as innovation, constraints from the district’s organizational environment, and uncertainty lead to a focus on performance conditions more than institutional capacity. The study draws on ethnographic research and in-depth interviews conducted with upper and middle managers of this school district.  相似文献   

Perpetration patterns and environmental contexts of IPV in Sweden: Relationships with adult mental health     

Laura E. Miller  Åsa Källström Cater  Kathryn H. Howell  Sandra A. Graham-Bermann 《Child abuse & neglect》2014

Although excellent data exist on the overall prevalence of childhood exposure to intimate partner violence (IPV), there is less information available on the specific patterns of IPV exposure in childhood and how they influence adult mental health. The current study examines 703 Swedish adults who reported exposure to IPV in childhood. Participants were part of a large national study on violence exposure. They provided an extensive history of their exposure to IPV and maltreatment experiences during childhood via electronically administered questionnaires. Mean comparison and multivariate regression methods were employed to assess differences in violence severity by reported perpetration pattern (mother-only, father-only, bidirectional or other), the association between violence severity and environmental context, and the contribution of these characteristics to adult mental health outcomes. Overall, violence perpetrated in public and by fathers was more severe and was related to poorer mental health outcomes in adulthood for child witnesses. These findings provide important insight into possible clinical “flags” for identifying children at high risk for exposure to IPV and abuse in the home.  相似文献   

Unpacking Rouché’s Theorem     

Russell W. Howell  Elmar Schrohe 《PRIMUS》2017,27(8-9):801-813

Abstract

Rouché’s Theorem is a standard topic in undergraduate complex analysis. It is usually covered near the end of the course with applications relating to pure mathematics only (e.g., using it to produce an alternate proof of the Fundamental Theorem of Algebra). The winding number provides a geometric interpretation relating to the conclusion of Rouché’s Theorem, but most undergraduate texts give no geometric insights that lead to an understanding of why Rouché’s Theorem holds. In addition, most texts do not inform students that a stronger version of the theorem exists. In this paper we present a simplified proof of the stronger version, which is a suitable topic for students to pursue as a short project, and provide a geometric argument for the weaker version. Finally, as a project for advanced students, we unpack a standard application of this theorem as used in control systems: the Nyquist stability criterion.  相似文献   

The Robustness of the Analysis of Variance and the Tukey WSD Test under Various Patterns of Heterogeneous Variances     

John F. Howell  Paul A. Games 《Journal of Experimental Education》2013,81(4):33-37

The WSD and F tests show the same response when the homogeneous variance assumption is violated. Both are robust when the ns are equal, but may be either seriously conservatively biased or seriously permissively biased when heterogeneous variances are combined with unequal ns. The use of equal ns is recommended for either test. There is no virtue in insisting that the F test be significant prior to conducting the WSD when the alternative to the null is μ_i ≠ μ_j. However, the conservative bias created by this procedure is small when K = 4; as is the permissive bias created by conducting both tests. For uniformly distributed μ’s, the two tests have very similar powers. This condition would not be expected for different arrangements of the μ’s.  相似文献   

“Thank God for Mississippi!” How Disparagement of the South Has Destroyed Public Schooling in New Orleans—and Beyond     

Charles Howell 《Peabody Journal of Education》2013,88(3):355-364

Reasons for neglect of homeschooling in educational research literature are explored. The ideological hostility that occasionally surfaces in policy debates is unlikely to have a major influence on mainstream researchers. An alternative explanation based on Kuhn's concept of normal science is proposed. The dominant paradigm of educational research emphasizes quantitative analyses, standardized settings, and large randomized samples. Unlike homeschooling, public schools, with their state-mandated curricula, age-graded classrooms, and tight regulation of facilities and personnel, provide an ideal setting for this paradigm. The congruence between setting and method is reinforced by universities. The training of licensed public school teachers generates most of the revenue that supports faculty positions in colleges of education. Consequently there is little incentive to study homeschooling. The article concludes that a scientific revolution in educational research is not in prospect. Moving beyond the current neglect will require a change in approach in investigating homeschooling. Rather than focusing on holistic comparisons, aimed at demonstrating the superiority of one educational mode over another, homeschool researchers can gain mainstream attention by investigating factors that affect motivation and learning across educational contexts, thereby generating results that would be useful to both public school teachers and home educators.  相似文献
