Predicting first-time-in-college students’ degree completion outcomes

Higher Education - About one-third of college students drop out before finishing their degree. The majority of those remaining will take longer than 4 years to complete their degree at...     

Language and reading impairments are associated with increased prevalence of non-right-handedness

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6–19 years old; European ethnicity) using a priori set criteria. A meta-analysis (N_cases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06–1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions.     

Measuring the Impact of Professional Accreditation on Student Experiences and Learning Outcomes

This research uses a conceptual model to examine the influence of a change in accreditation standards on a representative national sample of 203 engineering programs at 40 institutions. Based on data collected from more than 140 program chairs, 1,200 faculty, 4,300 graduates of 2004, and 5,400 graduates of 1994, the study investigates the differential impact of the change in accreditation standards on programs reviewed in different years during the period of transition. Despite significant variation across most of the measures and groups in 1994 (before the introduction of the new accreditation criteria), the 2004 evidence demonstrates a surprisingly uniform level of student experiences and outcomes. These findings suggest that engineering accreditation is beginning to accomplish its quality assurance goals. This is a revised version of a research paper presented at the meeting of the Association for Institutional Research, May 17, 2006, Chicago, IL.     

Sexuality education： Analysis of Moroccan teachers＇ and future teachers＇ conceptions

Conceptions are analyzed as being the emergences from interactions between three poles： scientific knowledge （K）, values （V） and social practices （P）. The teachers＇ beliefs and values have a direct influence on the way of understanding and teaching a topic. These beliefs must be taken into account in the content and strategies of the teacher＇s formation. In this paper, the authors discuss the importance of studying and analyzing these conceptions and present the results of the research on teachers＇ and future teachers＇ conceptions about sexual health education. In this topic, the conceptions could be deeply rooted not only in scientific knowledge but also in value systems and social practices, because teachers often refuse to teach the ethical, psychological, economic and social issues not strictly reducible to biology, such as sexuality health. The authors used a questionnaire prepared jointly within the European project Biohead-Citizen.     

Impaired acuity of the approximate number system underlies mathematical learning disability (dyscalculia)

Many children have significant mathematical learning disabilities (MLD, or dyscalculia) despite adequate schooling. The current study hypothesizes that MLD partly results from a deficiency in the Approximate Number System (ANS) that supports nonverbal numerical representations across species and throughout development. In this study of 71 ninth graders, it is shown that students with MLD have significantly poorer ANS precision than students in all other mathematics achievement groups (low, typically, and high achieving), as measured by psychophysical assessments of ANS acuity (w) and of the mappings between ANS representations and number words (cv). This relation persists even when controlling for domain-general abilities. Furthermore, this ANS precision does not differentiate low-achieving from typically achieving students, suggesting an ANS deficit that is specific to MLD.     

The role of gender constancy in early gender development

Kohlberg's (1966) hypothesis that the attainment of gender constancy motivates children to attend to gender norms was reevaluated by examining these links in relation to age. Ninety-four 3- to 7-year-old children were interviewed to assess whether and how constancy mediates age-related changes in gender-related beliefs. As expected, results indicated a general pattern of an increase in stereotype knowledge, the importance and positive evaluation of one's own gender category, and rigidity of beliefs between the ages of 3 and 5. Moreover, the stability phase, rather than full constancy, mediated some of these relations. After age 5, rigidity generally decreased with age, with relations primarily mediated by consistency.

Proclaiming Library Worth in a Program Prioritization Process at a Mid-Sized Public University

Abstract

In an economic climate when colleges can no longer presume that legislators see institutions of higher learning as tacit public goods, institutions around the country are facing budget cuts. This article presents a case study of the experience of a mid-sized public state university and its Library in a budget crisis undergoing a university-wide program prioritization process. The authors review the process of writing three reports on the Library’s value, along with the approach to engaging staff in the process including a retreat. This article raises questions about what every library should consider assessing and provide tools for libraries navigating similar terrain.     

Sex Education Legislation and HPV Vaccination Rates among Adolescents in the United States

Abstract

This study sought to determine if human papillomavirus (HPV) vaccination rates are associated with teaching requirements for abstinence in state sex education laws and policies. A cross-sectional analysis was conducted assessing the association between abstinence education legislation and HPV vaccination rates in adolescents (aged 13–17?years). After adjustment for insurance coverage and household income, the level of abstinence education was not significantly associated with vaccination rates. However, a higher percentage of individuals uninsured was significantly and negatively associated with the vaccination rate. This suggests that HPV vaccination rates are associated with insurance coverage, but not with the degree to which sex education laws or policies emphasize abstinence.
