For years, a popular explanation for women choosing to abandon studies in science, technology, engineering, and mathematics (STEM) has been their lack of aptitude. This study challenged that notion by integrating theories of cognitive style, academic emotion, self-efficacy, and motivation to explain students’ academic achievement and perseverance in STEM when transitioning to college. A sample of 1597 high school and junior college students participated. Exploratory and confirmatory factor analyses were first conducted to validate a reduced version of the cognitive style questionnaire. Structural equation modeling revealed that the cognitive style known as systemizing indirectly predicted STEM achievement and persistence by way of intrinsic motivation, learning anxiety, and self-efficacy, providing a new perspective for re-examining the gender gap in STEM.
This study focused on the use of the Artemis web-based interface http://artemis.goknow.com/artemis/index.adp). This program provides a digital library for students to search, organise, and evaluation science information related to project-based investigations. The primary feature of the Artemis interface is a focused search tool. Key scaffolding features in Artemis include the collections of web sites, driving question folders, a persistent workspace for notes, cataloging of past search results, and the viewing of sites shared by other students. The primary goal of this study was to describe high school science students' use of the scaffolding features embedded in the Artemis interface. The researchers were interested in identifying the scaffolding features students use and describing how they use them in the context of finding science information related to investigations. In addition, to look at scaffolding interaction, relationships between feature use and student learning were examined. The context of this study was a four-week science investigation conducted by 43 high school biology students. Students worked in dyads to answer driving questions related to their topics of study (e.g., What do the conditions need to be in order for green algae to survive?). It was found that students relied heavily upon Organisational Feature scaffolds (persistent workspace) to help them organise information that was ultimately used by the students to produce domain specific artifacts. In addition, students spent much of their time conducting searches and saving results. However, classroom performance success was only significantly correlated with the use of Organizational Feature scaffolds – scaffolding features that students use to create driving questions, write notes about the information they found as a result of their searches, and keep track of their investigations. No other search tool used by the students possessed this important scaffolding feature. The students did not automatically use Collaborative Features – scaffolding features hypothesised to be powerful cognitive tools. 相似文献
Standardised and other multiple-choice examinations often require the use of an answer sheet with fill-in bubbles (i.e. ‘bubble’ or Scantron sheet). Students with disabilities causing impairments in attention, learning and/or visual-motor skill may have difficulties with multiple-choice examinations that employ such a response style. Such students may request and receive testing accommodations that intend to mitigate these impairments, such as circling responses in a test booklet, which contains both the questions and corresponding multiple-choice answers. The current study evaluated this test accommodation as compared to using a bubble sheet or Scantron on a multiple-choice vocabulary test. College students with (n = 25) and without (n = 76) disabilities completed a vocabulary test under both booklet (accommodated) and bubble sheet (standard) conditions. Results demonstrated that answering in a test booklet, a much preferred response mode, allowed students to attempt significantly more items than using a bubble sheet, improving their overall test scores. Booklet responding tends to improve overall performance, even for students without disabilities, calling into question the specificity and validity of this accommodation. 相似文献
Using a conceptual model, this study examines the variables associated with the U.S. News and World Report peer assessment
ratings of graduate and professional schools in business, education, engineering, law, and medicine. What are the correlates
of prestige among the nation’s leading graduate and professional schools, and are they consistent with prior studies of prestige?
Not since the studies of the 1995 National Research Council (NRC) data have scholars examined the correlates of prestige for
individual graduate programs, and no study has ever extensively examined the U.S. News graduate ratings. Using available data
from U.S. News, as well as institutional websites and ISI Web of Science information, this analysis finds robust relationships
between the U.S. News graduate school reputation ratings and the model-relevant indicators, especially enrollment size, admissions
test scores, and faculty publications per capita. 相似文献
This paper discusses trends in contemporary Danish early childhood education and care (ECEC). Data are sourced from various policy documents, along with material from ongoing research projects in which the authors are involved. It is claimed that contemporary policy on Danish day care services has a tendency to emphasize narrow curriculum improvements and standardized testing. The democratic dimensions are still relatively strong, but at the moment these dimensions are interpreted within a skills‐and‐testing framework, which is leading to a situation where the political masquerades as the technical. 相似文献
Force plates represent the “gold standard” in measuring running kinetics to predict performance or to identify the sources of running-related injuries. As these measurements are generally limited to laboratory analyses, wireless high-quality sensors for measuring in the field are needed. This work analysed the accuracy and precision of a new wireless insole forcesensor for quantifying running-related kinetic parameters. Vertical ground reaction force (GRF) was simultaneously measured with pit-mounted force plates (1?kHz) and loadsol® sensors (100?Hz) under unshod forefoot and rearfoot running-step conditions. GRF data collections were repeated four times, each separated by 30 min treadmill running, to test influence of extended use. A repeated-measures ANOVA was used to identify differences between measurement devices. Additionally, mean bias and Bland–Altman limits of agreement (LoA) were calculated. We found a significant difference (p?.05) in ground contact time, peak force, and force rate, while there was no difference in parameters impulse, time to peak, and negative force rate. There was no influence of time point of measurement. The mean bias of ground contact time, impulse, peak force, and time to peak ranged between 0.6% and 3.4%, demonstrating high accuracy of loadsol® devices for these parameters. For these same parameters, the LoA analysis showed that 95% of all measurement differences between insole and force plate measurements were less than 12%, demonstrating high precision of the sensors. However, highly dynamic behaviour of GRF, such as force rate, is not yet sufficiently resolved by the insole devices, which is likely explained by the low sampling rate. 相似文献
