关于幼儿教育价值和现状的沉思

人类文明延续到今天,人们对早期教育与人生健康发展、社会和谐进步关系的认识日益充分,因而幼教神圣的观念正被更多的人所接受;与此形成反差的是,我们周遭的幼教现状堪忧:业内外不少人轻视幼教,这几年幼教事业整体上有所滑坡,有关幼教政策法规的落实、对幼教的监管和经费投入不到位。加强政府监管、改善幼儿园教师的生存状态、加大对幼教的投入力度、为幼儿教育立法等等,应视为改变现状的主要对策。

An Agenda for the Future: Student Portfolios in Social Work Education

Portfolios have been used in a variety of academic settings for outcomes measures and to present students' best work. This article introduces the idea of electronic portfolios to be used with social work majors both in the graduate and undergraduate curriculums. The literature around portfolios, an explanation of our process and the points to consider regarding pursuing an electronic portfolios process are addressed.     

The Complexity of Evidence-Based Practice: A Case Study

In this article, the author addresses areas of complexity within evidence-based social work practice that she has encountered in her work with clients. The author offers an in-depth case study from her practice that involves the assessment and treatment of a client with a complicated diagnostic presentation. Clinical choices are discussed using a biopsychosocial framework that highlights the importance of attending to the client's specific needs as the author select interventions based on the best available research.     

Improving response to an establishment survey through the use of web-push data collection methods

ABSTRACT

The web-push method has been shown to increase web response rates in general public surveys. Response rates from two waves of the Emergency Medical Services for Children Program’s Performance Measures Survey, a state-administered establishment survey, were compared to determine if the second wave's revised, centralized implementation strategy improved response rates and consistency across states. The centralized strategy included the web-push design; a carefully timed contacts; and a three-month timeline. The results of the centralized web-push method included a higher overall response rate for a three-month period (81.0% compared to 56.6%) as well as greater consistency in results across states.

On Some Two- and Three-dimensional D-minimax Designs for Estimating Slopes of a Third-order Response Surface

Design of experiments is considered for the situation where estimation of the slopes of a response surface is the main interest. Under the D-minimax criterion, the objective is to minimize the generalized variance of the estimated axial slopes at a point maximized over all points in the region of interest in the factor space. For the third-order model over spherical regions, the D-minimax designs are derived in two and three dimensions. The efficiencies of some two- and three-dimensional designs available in the literature are also investigated.     

Covariance Analysis for Split-Plot and Split-Block Designs

Commentaries are informative essays dealing with viewpoints of statistical practice, statistical education, and other topics considered to be of general interest to the broad readership of The American Statistician. Commentaries are similar in spirit to Letters to the Editor, but they involve longer discussions of background, issues, and perspectives. All commentaries will be refereed for their merit and compatibility with these criteria.

Proper methodology for the analysis of covariance for experiments designed in a split-plot or split-block design is not found in the statistical literature. Analyses for these designs are often performed incompletely or even incorrectly. This is especially true when popular statistical computer software packages are used for the analysis of these designs. This article provides several appropriate models, ANOVA tables, and standard errors for comparisons from experiments arranged in a standard split-plot, split–split-plot, or split-block design where a covariate has been measured on the smallest size experimental unit.
