The purpose of this study was first to assess and then to improve the diet of Greek primary school children teaching them healthy dietary habits and instructing them to face critically advertisements and media projected dietary models using a program which included intervention on cognitive, emotional, and social level. The results show that our intervention was more effective on the cognitive level and in particular on children's ability to estimate the dietary value of different kinds of food. However, their food preferences were not affected significantly, suggesting that these are more resistant to change since they are already consolidated and, therefore, need longer intervention. 相似文献

This study investigated a method to evaluate mediational processes using latent growth curve modeling. The mediator and the outcome measured across multiple time points were viewed as 2 separate parallel processes. The mediational process was defined as the independent variable influencing the growth of the mediator, which, in turn, affected the growth of the outcome. To illustrate modeling procedures, empirical data from a longitudinal drug prevention program, Adolescents Training and Learning to Avoid Steroids, were used. The program effects on the growth of the mediator and the growth of the outcome were examined first in a 2-group structural equation model. The mediational process was then modeled and tested in a parallel process latent growth curve model by relating the prevention program condition, the growth rate factor of the mediator, and the growth rate factor of the outcome. 相似文献

This study evaluated a 2‐week residential program aimed at enhancing the science interest and persistence of high‐achieving 8th‐grade girls. Questionnaires were administered to 38 program participants (14 of whom were of minority ethnicity) and 173 applicants who did not attend the program, at 3 time points: preprogram, 1 year postprogram, and 4 years postprogram. Outcomes, measured postprogram, included science self‐concept and interest, persistence and aspirations in science, science activities, science course‐taking in high school, and plans for a science college major. There was no main effect of program participation on any of the outcome measures, but a significant Participation × Ethnicity interaction effect occurred for all but one of the outcome variables. At Time 2, and especially Time 3, nonminority participants tended to have the most positive outcomes, whereas minority participants tended to have the most negative outcomes, compared with applicants. Post hoc analyses showed that although nonminority girls overall were more advantaged, this difference did not explain results. Several interpretations for these findings are discussed, the most likely that some global feature of the program, not any intervention component, interacted over time with the girls' postprogram experience. © 2003 Wiley Periodicals, Inc.

This study evaluated the violence prevention effects of The Peacemakers Program, a school‐based intervention for students in grades four through eight. The program includes a primary prevention component delivered by teachers and a remedial component implemented by school psychologists and counselors with referred students. The teacher‐delivered component consists of a psychoeducational curriculum and procedures for infusing program content into the school environment. The study included almost 2,000 students in an urban public school system, with pre‐ and post‐program assessment and comparison to a control group. There were significant, positive program effects on six of the seven variables assessed, including knowledge of psychosocial skills, self‐reported aggression, and teacher‐reported aggression, with a 41% decrease in aggression‐related disciplinary incidents and a 67% reduction in suspensions for violent behavior. On some outcome variables, intervention effects were stronger for boys than girls and for middle school compared to upper elementary school students. © 2002 John Wiley & Sons, Inc. 相似文献

What are the effects of group size (individuals, pairs, and quads of students), gender, and ability grouping of 245 seventh- and eighth-grade students on achievement within an environment that uses microcomputers as tools in learning science process skills? A split-plot, multivariate factorial design was used to analyze the above factors and interactions among the factors. Analyses indicated that the only statistically significant result was a main effect on ability for the two response variables measured in the study. Major conclusions included: (1) teams of two and four members working together solved problems as effectively as individuals, (2) the lessons and procedures implemented in the manner described generated a gender-neutral achievement outcome in science, and (3) microcomputer, using a file-management program and structured activities, can be used as a tool to promote student learning of science process skills. 相似文献

Using data from a nationally representative sample, this study examined Head Start children's school outcome differences by the end of Kindergarten between children who attended Head Start program for two years and the ones who attended for one year. Propensity scores were used to match children who experienced different durations of the program on a series of demographic characteristics in order to achieve a precise estimation of the effects of program duration. The results showed that in comparison to a demographically comparable group of children who attended the Head Start program for one year, the children who experienced two years of intervention services had statistically significantly higher performance on all six academic and social outcome measures by the end of Kindergarten, which included PPVT, Woodcock–Johnson Reading Skills, Woodcock–Johnson Math Reasoning Skills, teacher-reported composite academic skills, preschool learning behaviors, and social skills. Policy and practice implications are discussed. 相似文献

The purpose of this study was to re-evaluate the validity of traditional admissions criteria—UGPA and GRE scores—in predicting academic success for students admitted to a counselor education program in the United States. In contrast to prior research, we also included the newer GRE-Analytical Writing scores in our analyses. In general, we found that both UGPA and GRE scores were useful for predicting both graduate grade point averages (GGPAs) and students’ scores on the Counselor Preparation Comprehensive Exam (CPCE). We also found that a discriminant model that included all four admission variables was useful for predicting program completion outcomes: successfully graduated, dropped out, or dismissed from the program. Implications for the admissions and screening process are presented. 相似文献

ABSTRACT This article describes the process of integrating special-education content into 2 delivery models used in 2 different general-education teacher-preparation programs for elementary-education majors at the University of Wyoming and Casper (Community) College. One program was the traditional 4- year undergraduate elementary-teacher preparation program; the other was a creative and resourceful way of offering the same program at one of the state's community colleges. The models were based on theoretical and practical applications of current teaching practices. These included the integration of special-education students into the general-education classroom. Students' reactions to what they were learning and implications for practice are included. 相似文献

An important goal of education in developing countries is to implement and improve early childhood education. A pre–post intervention–control design was used to compare a piloted-revised versus a regular preschool program offered by an organization in rural Bangladesh. After 7 months in operation, the quality of the piloted-revised program was higher than the regular program, though the regular program had also improved. Children attending pilot preschools made greater gains than children attending regular preschools on most outcome measures. Action research was conducted alongside the quantitative evaluation to study the process of the implementation and to identify areas for further improvement. 相似文献

This article is a condensed report of a 3-year empirical study exploring best policies and practices of urban educational reform, focusing on 22 major urban school districts that were involved in the Urban Systemic Initiative (USI) program, sponsored by the National Science Foundation. USI has been a catalyst for large-scale educational reform in mathematics and science. The model was based on 6 educational reform drivers: 4 process drivers (standards-based curriculum, instruction, and assessment; policy; resources; and broad-based support) and 2 student outcome drivers (student achievement and improvement of the historically underserved). Annual data from 21 USI sites were collected for up to 6 years (school years 1993–1994 to 1999–2000). Causal inferential models were explored among the process drivers (independent variables) and outcome drivers (dependent variables), linking policy implementation rubrics to quantitative student outcome data. 相似文献

A parent aide program using volunteer experienced mothers to prevent reabuse of children (tertiary prevention) has been highly successful (97% prevention) in Southern Adelaide, South Australia. The program was modeled on that described by Kempe and widely used in North America. Only minor modifications have been required to establish the program in South Australia. The outcome of the first five years' experience indicates that, despite a work load of more than 20 hours per month per client, less than 10% of volunteer parent aides withdrew from their two-year commitment to the program. The cost-benefit ratio of the program appears very low and the prevention of reabuse by mothers involved was less than that for other clients assessed by the Southern Metropolitan Child Protection Panel, which referred all cases for a parent aide in the five-year period reviewed. Difficulties in maintaining the program did arise but were dealt with by close liaison between the parent aide, the program coordinators, and the primary care worker in the community who was usually a social worker in the Department for Community Welfare. The parent aide program has proved a cost-effective and successful method of tertiary prevention. 相似文献

ABSTRACTResilience has been described as a paradigm for aging that is more inclusive than models that focus on physiological and functional abilities. We evaluated a novel program, Resilient Aging, designed to influence marginalized older adults’ perceptions of their resilience, self-efficacy, and wellness. The multiweek group program incorporated an inductive definition of resilience based on group members’ lived experiences. Outcomes evaluation for this pilot study included pre/postassessments on resilience, self-efficacy, and six wellness variables. Twenty-nine participants completed the program. Pre/post-assessment indicated a statistically significant multivariate change across the eight outcome variables. Increases in resilience, physical wellness, and emotional wellness, and decreases in social wellness and intellectual wellness accounted for most of the multivariate change. Resilient Aging is a participant-centered and strengths-based program that has potential for enhancing participants’ perceptions of resilience and wellness. The program can be administered within community settings to promote resilience and wellness among marginalized older adults. 相似文献

Feasibility trial of the school-based STRONG intervention to promote resilience among newcomer youth

There are thousands of refugee students in Canadian schools and many struggle with distress and trauma symptoms. Even those not demonstrating overt distress may face adjustment challenges. This paper describes the pilot of the Supporting Transition Resilience of Newcomer Groups (STRONG) program in ten schools. STRONG is a 10-session, manualized program focused on building skills and helping students process their migration journey. This pilot used a pragmatic mixed-methods approach to evaluate the feasibility of STRONG, with a focus on acceptability, implementation, and perceived utility of the intervention. Clinicians (n = 16) provided data at the training, throughout the intervention and at the end through clinician surveys and focus groups. Clinicians reported high levels of acceptability for the training and program. Implementation challenges included time constraints, external influences, and some challenges with language. Overall STRONG was seen to provide significant positive benefits for students in increasing connectedness, stress management, and coping strategies. Clinicians felt that students developed more positive self-image and had improved optimism. This feasibility trial of the STRONG program indicated the potential utility for promoting resilience and reducing distress among refugee students through a structured, school-based group intervention. 相似文献

Ethnic identity, information about the world of work, and mastery in specific career skills crucially impact the process of career development among minority adolescents. Identity and conflict management skills also affect one of the major stressors experienced by employees today: the work-family conflict. This paper presents a culturally appropriate career intervention program for increasing Israeli Arab adolescents’ self-efficacy to manage work and family roles, and feedback from 15 participants in a preliminary pilot intervention. The program comprised three units: identity exploration, information, and skill transfer. The intervention was grounded in the career development literature on minorities, on work-family conflict research, and on social cognitive career theory. The proposed strategy also included process variables comprising critical career intervention components. The program is seen as having potential for being implemented in other cultural contexts. 相似文献

The predictive value of a child abuse screening instrument on unselected populations is illustrated for varying hypothesized levels of child abuse prevalence in order to demonstrate outcome of a hypothetical national screening program. At any level of application, the prediction of false positives and false negatives suggests a low practical utility for an unacceptably high social cost. 相似文献

The purpose of this study was to test the effects of a comprehensive writing program for students with and without learning disabilities (LD) in inclusive general education classrooms. The program incorporated research‐based components including instruction in a prewriting planning strategy, narrative text structure, writing strategies, and the process approach to writing. The study was conducted in five fifth‐grade inclusive classrooms with 113 students (including 14 students with LD). A quasi‐experimental comparison‐group design was utilized, whereby three intact experimental classes received the writing intervention, and two intact comparison classes received traditional writing instruction. Measures included several writing indicators as well as state writing competency test scores. Results indicated that the students with and without LD in the experimental group made significant gains from pretest to posttest on several writing measures. Although students in the comparison group made some gains, the gains were related to fewer measures than the measures associated with experimental‐group gains, and the effect sizes were smaller. 相似文献
