We examine the equivalence of two construct‐a‐concept‐map techniques: construct‐a‐map with created linking phrases (C), and construct‐a‐map with selected linking phrases (S). The former places few constraints on the respondent and has been considered the gold standard; the latter is cost and time efficient. Both their products and processes are compared quantitatively and qualitatively as to total accuracy score, individual proposition scores, proposition choice, map structure complexity, proposition generation rate, and proposition generation procedures. We conclude that the two mapping techniques are not equivalent: The C technique is better than the S technique in capturing students' partial knowledge, even though the S can be scored more efficiently than C. Based on their characteristics, if used as an assessment tool, the C technique is more suitable for formative assessment while the S technique is a better fit for large‐scale assessments. © 2005 Wiley Periodicals, Inc.

Supplementation of urban home visitation with a series of group meetings for parents and infants: results of a "real-world" randomized, controlled trial     

Constantino JN  Hashemi N  Solis E  Alon T  Haley S  McClure S  Nordlicht N  Constantino MA  Elmen J  Carlson VK 《Child abuse & neglect》2001,25(12):1571-1581

OBJECTIVE: Home visitation has been shown to be effective in reducing rates of child maltreatment and in enhancing psychosocial outcomes in children and their parents. Even when available, however, it is underutilized by parents in some urban settings. We tested a supplemental 10-session group intervention for its ability to increase active participation in home visitation, enhance the quality of caregiving behavior of parents, and improve social developmental outcome in children. METHOD: A randomized controlled design was utilized, involving two separate cohorts of parents of 3- to 18-month old infants, totaling 148 parent-child dyads. The intervention focused on practical experience in promoting parent-infant attachment relationships. RESULTS: At 6 months follow-up, there was a substantial increase in the proportion of intervention group parents participating in home visitation, compared to parents in the control group (Fisher's exact p = .008). Parents in the intervention group exhibited a trend for improvement in their capacity to appropriately interpret infants' emotional cues (p = .08), independent of the effects of home visitation itself. Attrition in both the treatment and control groups was inversely associated with income and level of education. CONCLUSIONS: Group meetings may constitute an effective means of engaging stressed urban families in home visitation.  相似文献   

Nutritional intake in soccer players of different ages     

Ruiz F  Irazusta A  Gil S  Irazusta J  Casis L  Gil J 《Journal of sports sciences》2005,23(3):235-242

The purpose of this study was to evaluate the dietary practices of soccer players of different ages. The diets of the members of four soccer teams (mean ages of 14.0, 15.0, 16.6 and 20.9 years, respectively) were examined. Our results show that the caloric intake per kilogram of body mass was significantly higher among the youngest players when compared with the adult players (P < 0.05). The contribution of carbohydrates to total energy intake was lower than that recommended for athletes. This contribution decreased with age from 47.4% of total energy intake for the 14-year-olds to 44.6% for the adult players. No significant differences in protein or total fat intake were detected among the teams examined. Overall, our results show that the nutritional intake of the soccer players was not optimal, and that this intake was poorer among the adult players than among the adolescents. On the basis of our results, we recommended that nutritional education should be given to soccer players at an early age and should continue throughout adolescence, not only with a view to improving performance but also to promoting more healthy dietary practices in the long term.  相似文献   

Findings From a Multiyear Scale-Up Effectiveness Trial of Open Court Reading     

Michael Vaden-Kiernan  Geoffrey Borman  Sarah Caverly  Nance Bell  Kate Sullivan  Veronica Ruiz de Castilla 《Journal of research on educational effectiveness》2018,11(1):109-132

This multiyear scale-up effectiveness study of Open Court Reading (OCR) involved approximately 4,500 students and more than 1,000 teachers per year in Grades K–5 from 49 elementary schools in seven districts across the country. Using a school-level cluster randomized trial design, we assessed the implementation and effectiveness of Open Court Reading over two years. Implementation study results demonstrated adequate to high levels of fidelity across the treatment schools. Intent-to-treat analyses revealed no statistically significant main effects on students’ reading performance in Year 1 and a small negative effect (d = – .09) in Year 2. There were positive impacts for particular subgroups, including kindergarten (d = .12) and Hispanic (d = .10) students in the first year. However, there were negative impacts for first grade (d = –.13), females (d = –.11), students who were not eligible for free or reduced-price lunch (d = –.19), and non-English language learners (d = –.10) in the second year of the study. Thus, relative to the “business-as-usual” reading curricula, no positive overall impacts of OCR and mixed impacts for student subgroups were found.  相似文献   

El profesor como práctico reflexivo en una cultura de colaboración

The aim was the reconstruction of a school curriculum in reflective teaching situations within a co‐operative culture. Two working assumptions were considered: (a) teacher development was based on teacher thinking and (b) school organisation followed a co‐operative culture paradigm. The process features were: (a) university team consisted of external advisers; (b) school curriculum and classroom instruction were reviewed by school teachers; (c) case study as a research approach; (d) ethnographic techniques to collect data; (e) data analysis by a computer program; (f) teachers’ reflective cycle to reconstruct practice; and (g) teachers’ portfolios: narrative vignettes, etc. Findings showed: (a) a collaborative process school‐university; (b) teachers’ thinking and attitudinal change; (c) mobilisation of teachers’ talents and values to work together: (i) teacher dyads to reflect on teaching; (ii) advisers’ writing narrative vignettes; (Hi) collegial coaching; and (iv) curriculum materials designed by teachers. Two conclusions can be accepted: (a) teachers’ pedagogical practical knowledge showed diversity of their implicit theories to design action; and (b) teachers’ grounded theory confirmed that the educational action was based on a co‐operative and reflective culture.  相似文献   

Utopia and pessimism: ‘You should not forsake the ship in a storm because you cannot command the winds’     

Encarnación Ruiz Callejón 《Educational Philosophy and Theory》2019,51(3):335-345

Abstract

One of the phenomena of our times is our low tolerance to negativity and frustration. Traditionally, philosophy has been given the task of dealing with emotions and offering suggestions to improve our world. The work of Thomas More, which gives rise to the name of the utopian genre, raises an important challenge; the philosopher Raphael Hythloday, who describes society on the island of Utopia, nevertheless rejects entering politics to attain the ideal. My intention is to address the issues raised by the work at two levels: what is Hythloday’s choice and whether his and other lessons in pessimism are useful in utopian thought.  相似文献   

Developing and evaluating instructionally sensitive assessments in science     

Maria Araceli Ruiz‐Primo  Min Li  Kellie Wills  Michael Giamellaro  Ming‐Chih Lan  Hillary Mason  Deanna Sands 《科学教学研究杂志》2012,49(6):691-712

The purpose of this article is to address a major gap in the instructional sensitivity literature on how to develop instructionally sensitive assessments. We propose an approach to developing and evaluating instructionally sensitive assessments in science and test this approach with one elementary life‐science module. The assessment we developed was administered to 125 students in seven classrooms. The development approach considered three dimensions of instructional sensitivity; that is, assessment items should: represent the curriculum content, reflect the quality of instruction, and have formative value for teaching. Focusing solely on the first dimension, representation of the curriculum content, this study was guided by the following research questions: (1) What science module characteristics can be systematically manipulated to develop items that prove to be instructionally sensitive? and (2) Are the instructionally sensitive assessments developed sufficiently valid to make inferences about the impact of instruction on students' performance? In this article, we describe our item development approach and provide empirical evidence to support validity arguments about the developed instructionally sensitive items. Results indicated that: (1) manipulations of the items at different proximities to vary their sensitivity were aligned with the rules for item development and also corresponded with pre‐to‐post gains; and (2) the items developed at different distances from the science module showed a pattern of pre‐to‐post gain consistent with their instructional sensitivity, that is, the closer the items were to the science module, the larger the observed gains and effect sizes. © 2012 Wiley Periodicals, Inc.

Personal Digital Assistants as Point-of-Care Tools in Long-Term Care Facilities: A Pilot Study     

Syeda S. Qadri  Jia Wang  Jorge G. Ruiz  Bernard A. Roos 《Educational gerontology》2013,39(4):296-307

This study used both survey and interview questionnaires. It was designed to assess the feasibility, usability, and utility of two point-of-care tools especially prepared with information relevant for dementia care by staff nurses in a small, a medium-sized, and a large nursing home in Florida. Twenty-five LPN or RN nurses were recruited for the study of their use of one of the tools—either a set of pocket cards (used by the control group) or a pocket PC (used by the experimental group). The findings of our study indicate that personal digital assistants (PDAs) can potentially improve long-term care clinicians' effectiveness and efficiency at work, resulting in better patient care for nursing home residents.  相似文献   

Using data mining to predict K–12 students' performance on large‐scale assessment items related to energy     

Xiufeng Liu  Miguel E. Ruiz 《科学教学研究杂志》2008,45(5):554-573

This article reports a study on using data mining to predict K–12 students' competence levels on test items related to energy. Data sources are the 1995 Third International Mathematics and Science Study (TIMSS), 1999 TIMSS‐Repeat, 2003 Trend in International Mathematics and Science Study (TIMSS), and the National Assessment of Educational Progress (NAEP). Student population performances, that is, percentages correct, are the object of prediction. Two data mining algorithms, C4.5 and M5, are used to construct a decision tree and a linear function to predict students' performance levels. A combination of factors related to content, context, and cognitive demand of items and to students' grade levels are found to predict student population performances on test items. Cognitive demands have the most significant contribution to the prediction. The decision tree and linear function agree with each other on predictions. We end the article by discussing implications of findings for future science content standard development and energy concept teaching. © 2007 Wiley Periodicals, Inc.
