The present study was designed to explore the association between preschool academic skills and Grade 3 achievement among a sample of ethnically diverse children from low-income families. Data were collected from a sample of 1,442 low-income, ethnically diverse children in preschool and associated with Grade 3 achievement in reading and mathematics 4 years later. Mixed-effects modeling indicated that preschool skills significantly predicted Grade 3 achievement measures while controlling for various child-level factors and random school effects. While several preschool factors were predictive of Grade 3 achievement, writing/copying and counting/premathematics skills were consistently strong predictors of Grade 3 achievement across all measures and domains suggesting these are important foundational skills for academic success in midelementary school among low-income, ethnically diverse children. Findings also replicate studies demonstrating that writing plays an important role in learning and achievement. Findings have implications for early education policy and practice intended to support academic development among low-income, ethnically diverse children. 相似文献

Objective:
The research sought to establish a rubric for evaluating evidence-based medicine (EBM) point-of-care tools in a health sciences library.Methods:
The authors searched the literature for EBM tool evaluations and found that most previous reviews were designed to evaluate the ability of an EBM tool to answer a clinical question. The researchers'' goal was to develop and complete rubrics for assessing these tools based on criteria for a general evaluation of tools (reviewing content, search options, quality control, and grading) and criteria for an evaluation of clinical summaries (searching tools for treatments of common diagnoses and evaluating summaries for quality control).Results:
Differences between EBM tools'' options, content coverage, and usability were minimal. However, the products'' methods for locating and grading evidence varied widely in transparency and process.Conclusions:
As EBM tools are constantly updating and evolving, evaluation of these tools needs to be conducted frequently. Standards for evaluating EBM tools need to be established, with one method being the use of objective rubrics. In addition, EBM tools need to provide more information about authorship, reviewers, methods for evidence collection, and grading system employed.Highlights
- Eleven of the fourteen previous evidence-based medicine (EBM) tool evaluations were based on clinicians evaluating tools based on their perception of the products'' ability to answer a clinical question.
- EBM tools'' evidence summaries are not updated as often as products claim.
- Although many EBM tools claim to be evidence based, only 74% of the 70 evaluated treatment summaries included graded evidence.
Implications
- To offer the best tools for users, medical libraries should evaluate EBM resources regularly, including the quality of the evidence provided.
- Medical librarians have a role to play in evaluating the quality of EBM products and can develop assessment tools to aid in this evaluation.

Question:
Can e-readers loaded with medical textbooks and other relevant material benefit medical students, residents, and preceptors in clinical settings?Settings:
The settings are North Carolina community clinics served by Duke University Medical Center and St. Joseph''s Hospital in Bryan, Texas, and Scott and White Memorial Hospital in Temple, Texas.Methods:
Duke University: Twenty second-year medical students and fourteen family medicine clerkship preceptors used Kindle e-readers in clinics during eight months of rotations. Students and preceptors provided feedback through an anonymous online survey. Texas A&M University: Nine fourth-year medical students in an elective compared medical textbooks in print, online, and on a Kindle. Six residents at a local hospital completed an anonymous online survey after a three-week loan of a Kindle loaded with medical textbooks.Results:
The e-reader''s major advantages in clinical settings are portability and searchability. The selected e-reader''s limitations include connection speed, navigation, and display. User preferences varied, but online resources were preferred. Participants suggested additional uses for Kindles in medical education.Conclusions:
The selected e-reader''s limitations may be resolved with further development of the device. Investigation of other e-readers is needed. Criteria for evaluating e-readers in clinical settings should include portability, searchability, speed, navigation, and display. Research comparing e-readers and mobile devices in clinical education is also warranted. 相似文献37.

The typical nursery school in the province of Quebec, Canada, is conducted in French, the official language of schools and business. Even so, it is not unusual to find English- as well as French-speaking students at many of these schools. Both languages are spoken in the province. 相似文献
