The lack of females entering STEM careers is well documented. Reasons for the gender gaps at all stages of the educational pipeline include both internal factors such as self-concept and external factors such as the influence of parents, media, and educators. Using latent growth curve analysis and nationally representative longitudinal survey data, this study compares differences in the relationship between a critical external factor (perceived early parental support), student mathematics and science achievement trajectories, and persistence in STEM career by gender. Mathematics and science trajectories were positively related to STEM career persistence for males and females. Perceived early parental support was related to growth in mathematics achievement for males but not females. There was no relationship between early perceived parental support and growth in science achievement for either males or females. These findings indicate differences in the relationship between parental support, achievement, and career persistence depending on content area and gender.  相似文献

The National Institute of Dental and Craniofacial Research (NIDCR), in collaboration with the Division of Oral Health, Centers for Disease Control and Prevention (DOH, CDC), has established a Dental, Oral and Craniofacial Data Resource Center (DRC). One element of the DRC is the Catalog of Surveys Related to Oral Health. The Catalog is a searchable electronic database that includes federal, state, international, and privately sponsored surveys and other datasets. Its purpose is to make researchers aware of surveys that have been conducted and to highlight features of complex surveys that relate to oral health. Other components of the DRC include an Archive of Procedures and Methods, Archive of Procedures and Methods Used in Oral Health Surveys, which is linked to the Catalog; an Annual Report, Oral Health U.S., 2002; and a data warehouse of acquired datasets. A Web-based statistical query system related to oral health is also under development. It is the intention of the DRC to meet the needs of NIDCR and DOH, CDC staff as well as other researchers interested in the status of oral health. The Catalog is available on CD-ROM at no cost and in the future will be made available through the NIDCR Web site.  相似文献

Despite the ease of accessing a wide range of measures, little attention is given to validity arguments when considering whether to use the measure for a new purpose or in a different context. Making a validity argument has historically focused on the intended interpretation and use. There has been a press to consider both the intended and actual interpretations and how users make sense of the data when constructing validity arguments, but the practice is not widespread. This paper contributes to existing research on validity by highlighting the value of attending to the actual interpretation and use of a measure aimed at supporting instructional improvement in mathematics. We describe the use of the same measure across two contexts to highlight the importance of attending to characteristics of both users and the contexts in which the measures are used when assessing the validity of inferences for the purpose of instructional improvement efforts.  相似文献

There is a need to identify students' early attitudes toward mathematics and science to better support their long-term persistence in science, technology, engineering, and mathematics (STEM) careers. Seventh graders from a nationally representative sample (N = 2,861) were classified based on their responses to questions about their attitudes toward mathematics and science using latent class analysis. Four distinct groups of students that differed in terms of their attitudes were identified. There were relationships between attitudinal group membership, demographic characteristics, mathematics and science achievement, and STEM career attainment. Females and underrepresented minorities were more likely to be in the positive attitude group. However, despite these early positive attitudes, females and underrepresented minorities were less likely to be employed in a STEM career some 20 years later. Information about student interests organized in this manner can be used to better target specific interventions to support and encourage persistence in STEM careers.  相似文献

The purpose of this study was to develop a valid and reliable tool for use in assessing motor skills in preschool children in field-based settings. The development of the Children's Activity and Movement in Preschool Study Motor Skills Protocol included evidence of its reliability and validity for use in field-based environments as part of large epidemiological studies. Following pilot work, 297 children (3–5 years old) from 22 preschools were tested using the final version of the Children's Activity and Movement in Preschool Study Motor Skills Protocol and the Test of Gross Motor Development (2nd Edition). Reliability of the Children's Activity and Movement in Preschool Study Motor Skills Protocol and interobserver reliability were determined using intraclass correlation procedures (intraclass correlation coefficients; ANOVA). Concurrent validity was assessed using Pearson correlation coefficients to compare the Children's Activity and Movement in Preschool Study Motor Skills Protocol to the original Test of Gross Motor Development (2nd Edition). Results indicated that test reliability, interobserver reliability, and validity coefficients were all high, generally above R/r = .90. Significant age differences were found. Outcomes indicate that the Children's Activity and Movement in Preschool Study Motor Skills Protocol is an appropriate tool for assessing motor development of 3-, 4-, and 5-year-old children in field-based settings that are consistent with large-scale trials.  相似文献

Today there is a growing global awareness of the need to address issues related to the safeguarding and use of both tangible and intangible heritage. By engaging with communities in the documentation of local cultures—especially their folklife, or in other words, their traditional intangible cultural heritage—museums can create collections that will serve as foundations for museum research, exhibitions, and programs that have more resonance with and relevance for those communities. Interactions of these kinds—in particular those of the Smithsonian's Center for Folklife and Cultural Heritage and the Michigan State University Museum, home of the Michigan Traditional Arts Program, as well as collaborations between the Smithsonian Folklife Festival and the Great Lakes Folk Festival, and other programs around the world—have served as important platforms for public discourse about a variety of issues and have produced programs and exhibitions both at home and around the world.  相似文献
