Pretend play by African American children in head start

Play behaviors of African American 4-year-olds from impoverished families were observed naturalistically. Children's free play was videotaped in Head Start classrooms over several weeks in the playhouse, block corner, and outside play yard. Play was categorized into cognitive play types—functional, constructive, and pretend play. Children most frequently engaged in functional play. Contrary to Smilansky's findings, impoverished children also engaged in pretend play. This play type was high in quality (object use, number of participants, and subtypes of pretense exhibited) but low in quantity (number and duration of play episodes) compared to other types of play. These findings are discussed in the context of theories of pretend play.     

Contextually-relevant validation of peer play constructs with African American head start children: Penn interactive peer play scale

The purpose of this investigation was to evaluate the construct and concurrent validity of a modified version of the Penn Interactive Peer Play Scale (PIPPS), a teacher-rating instrument of interactive play behaviors of preschool children. PIPPS were collected on 523 urban African American Head Start children. The PIPPS scales were confirmed, supporting the following constructs of peer play: Play Interaction, Play Disruption, and Play Disconnection. The 32-item PIPPS represented a significant improvement over the 36-item version. Scale validity was established using conceptually related indicators of social competence including teacher report, peer report, and direct play observation data. Children who evidenced high interactive play ratings received high social skill ratings from teachers, and were well liked by peers and engaged during play sessions. Children who were disruptive in play received ratings of low self-control and were more likely to be engaged in solitary play. Disconnection in play was associated with low acceptability by peers and lack of involvement in play sessions. Practical use of the PIPPS and further study of developmentally appropriate social competencies for African American Head Start children are discussed.     

The effectiveness of head start: Another look

This article focuses on the self-regulated learning processes of goal setting and perceived self-efficacy. Students enter learning activities with goals and self-efficacy for goal attainment. As learners work on tasks, they observe their own performances and evaluate their own goal progress. Self-efficacy and goal setting are affected by self-observation, self-judgment, and self-reaction. When students perceive satisfactory goal progress, they feel capable of improving their skills; goal attainment, coupled with high self-efficacy, leads students to set new challenging goals. Research is reviewed on goal properties (specificity, proximity, difficulty), self-set goals, progress feedback, contracts and conferences, and conceptions of ability. Ways of teaching students to set realistic goals and evaluate progress include establishing upper and lower goal limits and employing games, contracts, and conferences. Future research might clarify the relation of goal setting and self-efficacy to transfer, goal orientations, and affective reactions.     

The head start teaching center: An evaluation of an experiential,collaborative training model for head start teachers and parent volunteers

Forty-eight Head Start teachers and 48 parent volunteers from 24 classrooms were randomly assigned to either the Collaborative Training (CT) or Workshop Training (WT) approach. CT teachers and parents were involved conjointly in experiential training which included receiving guided practice and feedback from exemplary peers. WT consisted of a series of workshops conducted by outside trainers for separate groups of parents and teachers. Training methods were compared with respect to (a) teacher and parent reports of their level of involvement in training and satisfaction with the training experience, (b) teacher and parent reports of parent classroom activity, and (c) observation of adult-child classroom interactions. CT teachers and parents reported significantly greater levels of active involvement in and satisfaction with the training, as well as significantly greater levels of parent classroom activity than WT participants. With respect to adult-child classroom interactions, CT teachers demonstrated significantly more positive initiations and praise than WT teachers. Parent reports of their perceived role in the classroom as well as parent levels of initiation with children did not differ between training groups. Implications of these findings for further research were discussed.     

Conversations about head start salaries: A feminist analysis

This qualitative interview study investigates the Hoover Community Action Agency's Head Start salary policies as described by 3 program administrators and 10 teachers. Feminist theories explain how teachers' and administrators' interpretations of salaries reflect societal beliefs about the value of Head Start teaching. Head Start teachers acknowledge both their low wages and their deep commitment to the Head Start mission. Low- and middle-income teachers differ in how they describe current salary levels: low-income teachers are proactive in salary enhancement efforts and middle-income teachers view salaries as supplemental family income. Agency administrators, while acknowledging the low teacher wages, argue that Head Start employment is more financially lucrative than day care teaching. Administrators cite teacher commitment, not salary, as the best predictor of teacher tenure.     

Head start teaching center: Evaluation of a new approach to head start staff development

Head Start Teaching Centers are a national demonstration project designed to provide participatory training in all Head Start component areas within the context of an exemplary Head Start program. Each Teaching Center employs an independent evaluation to study this alternative approach to Head Start staff development. This paper presents the results of the outcome evaluation for the first year of the New England Head Start Teaching Center. The New England Head Start Teaching Center was designed to provide intensive training during a 3 or 5 day period of residence at the Teaching Center. This paper briefly describes the national Head Start Teaching Center model, the implementation of this model in the New England region, the outcome evaluation plan, and the results from the first year of training. The analyses of year one data indicated that training provided by the New England Head Start Teaching Center produced significant gains. As compared to similar Head Start employees who did not participate in training, both trainees and their supervisors reported significant gains in trainees' knowledge, skills, and expertise after participating in the New England Head Start Teaching Center training.     

Cortisol reactivity is positively related to executive function in preschool children attending head start

This study examined relations among cortisol reactivity and measures of cognitive function and social behavior in 4- to 5-year-old children (N = 169) attending Head Start. Saliva samples for the assay of cortisol were collected at the beginning, middle, and end of an approximately 45-min testing session. Moderate increase in cortisol followed by down-regulation of this increase was positively associated with measures of executive function, self-regulation, and letter knowledge but not with measures of receptive vocabulary, emotion knowledge, or false belief understanding. Regression analysis indicates that executive function accounted for the association between cortisol reactivity and self-regulation and letter knowledge.     

Father involvement program effects on fathers,father figures,and their head start children: a quasi-experimental study

An evaluation study was conducted to examine the effects of participation in a Head Start-based father involvement intervention program for fathers and their children. The study used a quasi-experimental research design that compared pretest and post-test measures for participants in four intervention sites against nonparticipants in geographically and demographically matched comparison (control) sites. The treatment and comparison groups were further divided into dosage groups based on the amount of time that fathers were involved in the program. The results suggest a positive association between high dosage participation in the intervention and increased father involvement with children at post-treatment. The children of high dosage intervention fathers also showed higher mathematics readiness change scores. Children in the low dosage comparison group showed a significant increase in behavior problems.     

Contributions of protective and risk factors to literacy and socioemotional competency in former head start children attending kindergarten

We empirically evaluated the associations of hypothesized protective and risk factors with assessments of social, literacy, and cognitive competence in a sample of Head Start graduates attending kindergarten in rural Georgia. The sample included 117 former Head Start children and their primary caregivers, who were assessed during the fall of the children's kindergarten year. The participating families—59% African American, 39% white, and 1 % Latin American—lived in four rural counties in northeast Georgia. Data were obtained from caregivers, teachers, and children, using a multimethod, multi-informant research design. Caregivers provided information about developmental goals, family processes, and their own psychological functioning; and the children and their kindergarten teachers provided socioemotional, literacy, and cognitive-competence information. The results support the hypothesized relations between the child-competence measures and protective factors, especially caregiver self-esteem, endorsement of independence-promoting developmental goals, co-caregiver support and communication, and engaged, responsive, and cognitively challenging caregiver-child interactions. The results also support the hypothesis that caregiver distress and conflicted family relationships are associated with negative developmental outcomes for former Head Start children attending kindergarten.     

Family and classroom correlates of head start children's developmental outcomes

Program quality is an important theme for Head Start. Even staunch supporters of Head Start are concerned that too few Head Start classes are of the quality that is needed to best promote children's growth and development. This study examined relationships between classroom quality and child outcomes among 145 Head Start children from poor quality to more stimulating home environments. Results indicated that children in higher quality Head Start classrooms performed better on measures of achievement and preacademic skills, regardless of the quality of their home environment. Children from better home environments seemed to benefit more from classroom quality in the area of problem solving and reasoning than did children from less stimulating homes. Teacher characteristics such as education, experience, and attitudes were not associated with classroom quality in this group of 32 Head Start classrooms. On the Early Childhood Environment Rating Scale, no classroom received a rating of inadequate, but only 9% met or exceeded the score that would be considered developmentally appropriate.
