Evaluation of curriculum online: report of the follow up survey of schools

This report contains the findings of the second survey of schools carried out as part of the evaluation of curriculum online. One questionnaire collected school-level information for each school and additional questionnaires collected data for selected subject areas

Curriculum online: final report

The Department for Education and Skills (DfES) commissioned NatCen and the University of Bristol to conduct a four-year evaluation of curriculum online, beginning in 2002. This is the final evaluation report for the programme, reviewing outcomes from the research

Evaluation of curriculum online: Report of the third survey of schools

This report, based on interviews with a range of teachers and pupils in a sample of primary and secondary schools in England, examined, in depth, how schools responded to the third year of the curriculum online programme. Report on the industry impact of curriculum onlin

Investigation of the Prevalence of Learning Disabilities Within the Home-School Population of Southwest Michigan

Problem. The special education needs of home-school children have rarely been studied. This research utilizes the homeschool population of Southwest Michigan to investigate the incidence of learning disabilities (LD) within this group. At the same time, it is possible to investigate some of the criticisms of the learning disability field of study. Method. Two hundred ninety-eight home-school children in southwest Michigan were assessed for LD using the Michigan State Board of Education definitional criteria. Achievement was assessed by use of the Wide Range Achievement Test, third revision. Ability was measured with the Wechsler Intelligence Scale for Children, third revision. A discrepancy of 18 standard score points was used to determine possible LD. Subjects were then examined for the presence of other factors that would explain the learning problems of subjects having a severe discrepancy between ability and achievement. Results. Of the sample group, 3.7% were found to exhibit learning problems that could not be explained by other than a diagnosis of LD. A significant relationship was found between levels of teacher involvement and the presence of learning problems. Conclusions. A lower prevalence of LD is found within the home-school population when compared with Board of Education figures of public school prevalence rates. However, this difference was not statistically significant. The concept of LD is problematic from the standpoint of definition and assessment and might better be conceived as Learning Difficulty Syndrome. Learning problems appear related to teacher involvement

Academic and Social Barriers to Black and Latino Male Collegians\u27 Success in Engineering and Related STEM Fields

Historically underrepresented racial/ethnic minorities (i.e. African Americans, Latinos, and Native Americans) have experienced barriers to their success in engineering and related STEM fields. These student populations have had lower degree attainment rates, switch to non-STEM majors more frequently, and experience unique social challenges when compared to White and Asian Pacific Islander counterparts. To examine these findings, nearly 50 interviews were conducted and analyzed in the present study to better understand the academic and social experiences of African American and Latino American men in these fields. Interviews revealed that these students tend to (1) feel alone and invisible, (2) lack same race peers and faculty members, (3) have difficulty applying theory to practice, and (4) lack the pre-college preparation necessary to succeed in STEM fields

Treatment-Mediated Alterations in HIV Fitness Preserve CD4+ T Cell Counts but Have Minimal Effects on Viral Load

For most HIV-infected patients, antiretroviral therapy controls viral replication. However, in some patients drug resistance can cause therapy to fail. Nonetheless, continued therapy with a failing regimen can preserve or even lead to increases in CD4+ T cell counts. To understand the biological basis of these observations, we used mathematical models to explain observations made in patients with drug-resistant HIV treated with enfuvirtide (ENF/T-20), an HIV-1 fusion inhibitor. Due to resistance emergence, ENF was removed from the drug regimen, drug-sensitive virus regrown, and ENF was re-administered. We used our model to study the dynamics of plasma-viral RNA and CD4+ T cell levels, and the competition between drug-sensitive and resistant viruses during therapy interruption and re-administration. Focusing on resistant viruses carrying the V38A mutation in gp41, we found ENF-resistant virus to be 17±3% less fit than ENF-sensitive virus in the absence of the drug, and that the loss of resistant virus during therapy interruption was primarily due to this fitness cost. Using viral dynamic parameters estimated from these patients, we show that although re-administration of ENF cannot suppress viral load, it can, in the presence of resistant virus, increase CD4+ T cell counts, which should yield clinical benefits. This study provides a framework to investigate HIV and T cell dynamics in patients who develop drug resistance to other antiretroviral agents and may help to develop more effective strategies for treatment
