Abstract

This study assessed 4th, 8th, and 11th grade students' understanding of natural and social science concepts related to pollution. A representative sample of public school students (n = 105) in 11 Maine schools was selected, and students were interviewed on four concept principles considered critical to a full understanding of the pollution problem. The concept of pollution included the much publicized issues of solid and toxic waste as well as air, soil, and water pollution. Research assertions were summarized in generalized correct concept statements indicating the extent of current student knowledge. Common misconceptions were also noted.

This study considered student understanding from a human ecological perspective, that is, as an integrated set or cluster of concepts related to pollution. This reflects a complex, integrated, and multidisciplinary conception of natural phenomena. Human constructivism, meaningful learning theory, and principles related to the relevance of student schema in the design of curriculum and instructional strategies guided this work.

The results of this study have implications for teaching about pollution and the design of science education curriculum materials based upon student knowledge. This information can guide teaching strategies concerning current environmental problems and thus help learners gain an appreciation for the complex and multi-disciplinary nature of science, technology, and society and how they affect the environment.  相似文献

This study builds on and contributes to work on assessment of children in primary school, particularly in science. Previous research has examined primary science assessment from different standpoints, but no studies have specifically addressed children's perspectives. This article provides additional insight into issues surrounding children's assessment in primary school and how the assessment of science might develop in England after the science SATs (Standard Assessment Tests) were abolished in 2009. Some research suggests that primary science assessment via SATs is a major reason for the observed decline in children's engagement with science in upper primary and lower secondary school. The analytic focus on engaging children as coresearchers to assist in the process of gathering informed views and interpreting findings from a large sample of children's views enables another contribution. The study, based on a survey of 1000 children in primary and secondary schools in England and Wales, reveals that despite being assessed under two different regimes (high‐stakes national tests in England and moderated teacher assessment in Wales), children's views of science assessment are remarkably consistent. Most appreciate the usefulness of science assessment and value frequent, non‐SATs testing for monitoring/improving science progress. There was a largely negative impact, however, of science assessment on children's well‐being, particularly due to stress. The paper demonstrates that children provide an important perspective on assessment and that including their views can improve policy‐making in relation to primary science assessment.  相似文献

Childhood sexual abuse (CSA) is relatively common and is associated with a multitude of negative outcomes in adulthood, including posttraumatic stress disorder (PTSD) and lower marital satisfaction. However, CSA has been understudied in military samples. The purpose of the present study was to examine the relative contributions of CSA and combat exposure to PTSD and marital satisfaction. Two hundred eighteen National Guard/Reserve veterans who deployed overseas between 2001 and 2008 completed self-report measures of CSA, marital satisfaction, combat exposure, and PTSD symptom severity. Data were analyzed using linear regression and path analysis to evaluate a comprehensive model including all variables. CSA accounted for unique variance in PTSD symptom severity independent of combat exposure. CSA also had a negative direct association with marital satisfaction, independent of combat exposure and PTSD symptom severity. In contrast, combat exposure had only a negative indirect association with marital satisfaction via PTSD when all variables were examined simultaneously. CSA accounted for unique variance in both PTSD symptom severity and marital satisfaction in this sample of combat veterans. Clinically, results suggest that assessment and treatment of CSA is indicated for military veterans suffering from PTSD. Further, treatment of CSA may improve marital satisfaction, which may positively affect psychological functioning in the veteran.  相似文献

This study examined elementary teachers’ instructional strategies for promoting scientific understanding and inquiry and supporting English language development with diverse student groups including English language learners. The study was part of a 5-year research and development project consisting of reform-based science curriculum units and teacher workshops aimed at providing effective science instruction to promote students’ science and literacy achievement in urban elementary schools. Data consisted of 213 post-observation interviews with third, fourth, and fifth grade teachers. The teachers reported using instructional strategies to promote scientific understanding, but generally did not employ more sophisticated inquiry-based strategies. They also reported using instructional strategies to support English language development. There were significant differences among grade levels and by years of teacher participation.  相似文献

This work was based on a case study of a university institute designed to bring university and industry leaders together to promote research and economic development. The article examines how key terms in technology transfer not only justified the institute but also constituted a ground for negotiating interests. Framed by Burke's and Bourdieu's theories of motive and space, the analysis examines the question of who or what authorizes the grounds for success in technology transfer.  相似文献

Recognition of the nontraditional student in higher education is valuable because it promotes an awareness of issues particularly relevant to the community college student population. While research that categorizes students by age is a practical way to study a unique population within community colleges, this approach may not be the most preferred way to examine the complexities of community college students. This study focused on community college students' self-perceptions of their primary roles as students, employees, and parents, thereby offering an alternative to utilizing predefined categories in order to distinguish between groups (e.g., based on age). The findings also shed light on unique characteristics that differentiate among students who identify their roles primarily as students, employees, or parents. In fact, this study shows that even students often considered “traditional” may have qualities that are typically considered nontraditional.  相似文献

The No Child Left Behind act resulted in an increased reliance on large-scale standardized tests to assess the progress of individual students as well as schools. In addition, emphasis was placed on including all students in the testing programs as well as those with disabilities. As a result, the role of testing accommodations has become more central in discussions about test fairness and accessibility as well as evidence of validity. This study seeks to examine whether there exists differential item functioning for math and language items between special education examinees receiving accommodations and those not receiving accommodations.  相似文献

ABSTRACT

Due to the implementation of a performance-based funding plan, community colleges in North Carolina must attain a minimum percentage of students successfully passing licensure and certification examinations. To meet this mandate, Catawba Valley Community College implemented a basic skills component, with minimum academic standards, to assist students in achieving success. This study found these measures significant in improving student pass rates on the EMT-Basic certification examination, despite nonsignificance related to student age or education levels.  相似文献
