The purpose of this study was to develop and verify the Index of Science Reading Awareness (ISRA) based on a model of an efficient, successful interactive-constructive science reader and three independent metacognitive awareness domains. Several researchers have noted the need for efficient, reliable, and valid measures of metacognition. ISRA data collected on 532 students (Grades 4–8) were analyzed using factor analyses, linear structural modeling, and analyses of variance (ANOVAs) to help verify the model and the test. The factor analyses and linear structural modeling indicated that these data did not support the assumption about the three independent metacognitive awareness domains, but suggested that the model and the test were structured around the design features of science reading, science text, and science reading strategies. One-way ANOVAs indicated significant, predicted reading ability and gender differences but unexpected grade-level differences. The composite metacognitive awareness data indicated that most Grade 4–8 students have surface knowledge about science reading, science text, and science reading strategies, and indicated specific targets for explicit science reading instruction. © 1998 John Wiley & Sons, Inc.

Current barriers hindering data-driven discoveries in deep-time Earth (DE) include: substantial volumes of DE data are not digitized; many DE databases do not adhere to FAIR (findable, accessible, interoperable and reusable) principles; we lack a systematic knowledge graph for DE; existing DE databases are geographically heterogeneous; a significant fraction of DE data is not in open-access formats; tailored tools are needed. These challenges motivate the Deep-Time Digital Earth (DDE) program initiated by the International Union of Geological Sciences and developed in cooperation with national geological surveys, professional associations, academic institutions and scientists around the world. DDE’s mission is to build on previous research to develop a systematic DE knowledge graph, a FAIR data infrastructure that links existing databases and makes dark data visible, and tailored tools for DE data, which are universally accessible. DDE aims to harmonize DE data, share global geoscience knowledge and facilitate data-driven discovery in the understanding of Earth''s evolution. 相似文献

Troubleshooting skills are integral for the Information Technology professional. In order to address faculty concerns that
students were not effectively learning required troubleshooting skills, a standardized troubleshooting methodology (the DECSAR
Method) was created and integrated into the standard curriculum of a college information technology program. Components of
troubleshooting were measured using a pre-/post-testing approach with the Social Problem Solving Inventory—Revised. Testing
indicated improvement in several areas of troubleshooting reinforced by DECSAR. The context in which the troubleshooting methodology
was applied was associated with post-test change.

As assistive technology applications are increasingly implemented in early childhood settings for children who are at risk
or who have disabilities, it is critical that teachers utilize observational approaches to determine whether targeted assistive
technology-supported interventions make a difference in children’s learning. One structured strategy that employs observations
and which has powerful child progress monitoring implications is the concurrent time series probe approach. Requiring multiple
performance measures of a child engaged in a targeted task over time—both with and without a specific assistive technology
device—the concurrent time series probe approach can be used to evaluate the effectiveness of assistive technology tools in
supporting skill acquisition in the classroom. This approach is described in the context of a case study, with accompanying
explanations of how to interpret data and make decisions regarding the effectiveness of the technology. 相似文献

This study aimed to provide evidence to guide decisions on the type and timing of assessments in a graduate medical programme, by identifying whether students from particular degree backgrounds face greater difficulty in satisfying the current assessment requirements. We examined the performance rank of students in three types of assessments and also calculated the relative risk of failure in the summative assessments for four cohorts over all four years of a four‐year graduate medical programme. Our findings suggest that early summative assessment may disadvantage the very students who create the diversity that the faculty values, particularly if methods such as Single Best Answer questions are used, unless students are provided with additional support in bridging their knowledge gap. Use of assessment methods such as Modified Essay Questions and Objective Structured Clinical Examinations appears to be more justifiable on educational grounds. 相似文献

In education, case studies have been employed as a major pedagogical means to engage students with realistic materials and
practical problems. The usefulness and success of case studies have been documented in literature. In this paper, we move
the case study and its technical affordance a step further toward more authentic or realistic learning and toward communities
of practice. Drawing on current intellectual achievement in education, developmental psychology and computer-supported collaborative
learning, this paper proposes four requirements for interactive case study libraries, focusing on authentic learning, social
interaction, resource accumulation, and communities of practice. With a usability engineering case study library as an example,
we discuss design concerns derived from these requirements as well as its use in practice. 相似文献

Artificial rugby union playing surface installation is increasing. This prospective cohort study aimed to examine the effect of playing surface on match injury types within 157 players of two UK professional rugby union clubs playing 209 matches (96 on artificial surfaces and 113 on grass) over three seasons. There was no difference in overall injury risk between the two playing surfaces with injury incidence on artificial 80.2 (CI 69.9–91.7) and on grass 81.9 per 1000 match-hours (CI 72.2–92.5), with an incidence rate ratio (RR) of 0.98 (CI 0.82–1.17). There was a higher rate of concussion (RR 0.52, CI 0.34 – 0.78) and chest injuries on grass (RR 0.26 CI 0.07, 0.95), and a higher rate of thigh haematoma (RR 2.25, CI 1.05–4.82) foot injuries (RR 4.12, CI 1.10, 15.40) and injury to players being tackled (RR 1.46, CI 1.00, 2.15) on artificial. Whilst there was no higher injury risk for matches played on artificial versus natural grass surfaces, the higher incidence of concussion and chest injury on grass, and the higher rate of foot injuries on artificial surfaces may be related to tackle and footwear-to-surface interface factors. 相似文献

We investigate two fundamental research questions related to the funding of early-stage technology enterprises. First, does presentation design, and the presenting entrepreneur's passion and preparedness, influence experts' assessment of the merit and commercialization potential of an emerging firm's technology? Second, are the entrepreneur's passion and preparedness during a formal presentation associated with future technology success? We analyze twenty-two video-taped presentations to a U.S. Department of Defense technology transfer and granting consortium, and track subsequent technology success. From the data it appears that both entrepreneurial passion and presentation design does influence expert assessment of a technology, and future commercialization success can be predicted to some extent by the level of entrepreneurial passion exhibited during the presentation. 相似文献
