Obesity among children is a public health concern. Preschool-­‐aged children, especially those from low-­‐income families, are no exception to the obesity epidemic. During the RD Parent Empowerment Program, parents of Head Start children in Johnson City, TN completed a structured education program over the course of 4 workshops related to healthy habits of families. The goal was to empower parents to shop smart, cook healthy, and eat right. The Family Nutrition and Physical Activity (FNPA) screening tool was used as an assessment tool to evaluate behavior change over the course of the program. Improvement in overall FNPA score was seen at the conclusion of the program. Individual assessment of breakfast consumption, family meal patterns, fruit and vegetable intake, beverage choices, and restriction occurred. Participation in the RD Parent Empowerment Program resulted in maintaining healthy behaviors or improved behaviors for many participants. A larger sample may provide more conclusive results.

Three questions are explored in this dissertation. The first is whether the executive functions of Head Start participants are improved in comparison to those of children who did not attend center-based care before attending kindergarten. By matching and comparing the outcomes of a nationally representative cohort of kindergarten children (ECLS-K:2011) grouped by the type of childcare they received in the year preceding school entry, I find that Head Start participants exhibit slightly higher cognitive flexibility scores (as well as reading and math outcomes) in comparison to highly similar children who did not experience center-based care before starting school. Children who participated in Head Start demonstrate working memory skills that are not significantly different from those of closely-matched children who experienced no center-based care, but their skills in this area are slightly weaker than those of similar children who attended school-based public pre-k or other center-based care. The second question is how math content level during kindergarten affects children with different early care experiences, with focus on Head Start participants. The use of piece-wise linear growth curves to analyze children’s development in working memory, cognitive flexibility, reading and math reveals that advanced math content in kindergarten does have a positive relationship with math and reading achievement for Head Start participants, but these students do not gain as much on average from this instructional approach as more advantaged groups do. More basic math content, such as counting has a negative association with growth in math for more advantaged groups of children. Finally, any increases in kindergarten growth rates resulting from math content do not appear to persist through first and second grades. The third question asks whether there are significant differences in the trajectories of Head Start participants according to parent nativity. In analysis using piece-wise linear growth curve models to analyze Head Start (HS) participants’ development in working memory, cognitive flexibility, reading and math, results indicate that HS participants with immigrant parents exhibit an additional surge in EF development in the period between the spring of kindergarten and the spring of second grade, later than the average kindergarten increase for all HS participants. Additionally, HS participants with immigrant parents exhibit slightly higher average growth rates in reading during kindergarten when compared to HS participants with non-immigrant parents.

In early childhood classrooms, transitions are often targeted as times of the day during which teachers encounter problems with deficiencies in child engagement, as well as frequent occurrences of challenging behavior. Studies to date on improving child behavior during in-class transitions have focused on providing supports for individual children, as well as on reducing transition duration. The present study evaluated the effects of systematic transition strategies, as applied to three Head Start preschool classrooms during targeted in-class transitions. Strategies encompassed an accumulation of antecedent and consequent manipulations and were selected on the basis of environmental fit with individual classroom environments. Participants included three Head Start preschool teachers and their respective students, all three to five years of age. The dependent measures examined in the study included mean percent classroom engagement and percent occurrence of challenging behavior, measured across all phases of the study (i.e., baseline, coaching and independent implementation). Results, evaluated in a multiple baseline probe across classrooms, indicated that with implementation of systematic transition strategies, mean percentages of classroom engagement within intervention phases (i.e., coaching and independent implementation) were higher and relatively more stable than those observed in baseline, within and across all three participating classrooms. Furthermore, mean percent occurrences of challenging behavior were lower and relatively more stable within phases of intervention (i.e., coaching and independent implementation) than those observed in baseline, within and across all three participating classrooms. Data on the accuracy with which teachers implemented selected strategies (i.e., treatment integrity) were also documented and presented in the context of results obtained. Implications for future research are discussed, in light of the limitations and findings of the current investigation.

Substantial evidence from previous research has supported the idea that greater self-regulation in the form of “cool” self-regulation or executive functioning and “hot” self-regulation or effortful control is associated with higher academic achievement within the preschool years and school readiness in the kindergarten years (Anaya, 2016; Carlson, 2005). However, there are only a few studies that assess the prediction of school readiness through validated cool and hot self-regulation tasks (Carlson, 2005; Krain, Wilson, Arbuckle, Kastellanos, & Wilham, 2006; Rothbart, Ellis, Rueda, & Posner, 2003; Thompson & Giedd, 2000). There also few studies examining to what extent cool and hot-self-regulation tasks predict socio-emotional (Blair, 2002) and academic achievement (Bull & Scherif, 2001), which are aspects of school readiness. The current study examined the validity of hot and cool tasks as measures of school readiness within a preschool sample (n = 86) enrolled in one of two programs: one blended Head Start and one full Head Start program. Adapted hot and cool self-regulation tasks, global observer ratings of hot and cool self-regulation tasks (Preschool Self-Regulation Assessment Assessor Report (PSRA-AR) and the Observation of Child Temperament Scale), Woodcock Johnson subtests (Letter Word, Applied Problems, and Picture Vocabulary), teacher ratings of social competence (Social Competence and Behavioral Evaluation) and emotional competence (Emotion Regulation Checklist) were collected in the fall of the school year. Results indicated that performance on cool tasks of measures cool self-regulation were highly correlated with academic performance and that the Snack Delay task and the PSRA-AR component scores (Attention/Impulse Control and Positive Emotion) of hot self-regulation were correlated with socio-emotional competence. Additionally, there were no age differences for hot self-regulation. Regression analyses suggested that hot self-regulation predicted socio-emotional competence and cool tasks predicted academic achievement. However, conclusions regarding hot self-regulation age differences and predictive validity are limited by the sole use of one hot task within this study and the results do not warrant a conclusion regarding whether hot self-regulation and cool self-regulation are separate self-regulation constructs, given the use of only one hot task.

The diploma thesis is focusing on the contemporary movement called "early start" in the education of the English language. Almost all nursery schools offer today the extra lessons for children. The diploma thesis presents not only the actual negative and positive arguments for the early start lessons but also the theoretical resource for the development of language and communicative competences of children. Also the topic of learning a foreign language and its influences as well as the politics of educating foreign languages in the world and in the Czech Republic are included. The practical part of the thesis will try to enrich the debate about the early start by individual experience and findings of six children who were interviewed. Their information was completed by the acquaintances of their parents that filled the questionnaire.

Children from non-English-speaking homes often lag behind their English speaking peers academically. However, people who speak two languages often have better executive functioning skills than people who speak only one language. Executive functions are neurologically-based skills related to managing oneself to achieve a goal. The relation between bilingualism and executive function may be due to how two languages are processed in the brain. However, it is unclear if more balanced bilinguals experience larger gains in executive function than people who are less balanced. Children from low-income homes are at a disadvantage as compared to children from homes with higher incomes. A quarter of children in the Head Start program, which serves children from low-income homes, come from homes that speak a language other than English which puts them at a double disadvantage. Longitudinal data from 3-year-old children enrolled in Head Start who were from Spanish-speaking households were used to investigate whether there were different patterns of dual language development and if those patterns related differently to executive function. Results revealed three groups of dual language development. Groups were compared in terms of children’s performance on a nonverbal executive functioning task. Results showed that children in the group that had the most similar proficiency between English and Spanish had the highest average executive functioning scores, even after controlling for child age and gender. This indicates balanced bilingualism may enjoy additional benefits to executive functioning development as compared to individuals with relative imbalance between languages.

This study examined the effects of a computer CD-ROM storybook program on 73 Head Start children in Logan, Utah. A variation on the two-group pretest/posttest design was used to determine if there was any increase in emergent literacy skills after spending an average of 15 minutes per day for an average of 12 days on the computer. Previous research suggests that a child's home environment is integral to the preschool child 's emergent literacy development. A parent questionnaire designed for assessing information regarding the child 's I iterate environment at home was administered. Mean scores indicated that those children scoring highest on an aggregate score of four questions from the parental questionnaire also scored highest on three assessments of emergent literacy, supporting previous research that children who have been read to at home are more prepared to learn reading in the classroom. Posttest scores indicated an increase in scores for the experimental group over the not-well-read-to control group on all three assessments. Two of the three measures indicated statistically significant differences from the well-read-to control group (p = < .05). One of the most interesting findings, however, was that the experimental group's assessment scores increased over the not-well-read-to control group, but did not exceed the well-read-to control group's scores, further supporting the evidence discussed above that children who are read to in the home have an advantage over those children who are not. From these results, it was determined that computers cannot take the place of effective instruction in the home; however, when used appropriately in the classroom, the results of this study suggest that it is useful to integrate computers in the preschool classroom to augment the emergent literacy instruction already taking place.

The effect of compensatory education was studied as it influences school readiness in preschool children . The research was conducted in the Logan and Providence areas of Cache County, Utah, with 44 children who had completed the kindergarten year of school. Twenty-two of the children had participated in the compensatory educational experience of Head Start prior to their kindergarten experience. It was found that there was not a significant difference between the Head Start children and their neighbors in terms of their performance on the Boehm Test of Basic Concepts. Therefore, in terms of school preparedness, the Head Start children seem to be equal to their peers in basic concept knowledge as they enter the first grade. The findings also indicate that additional studies will be needed to determine if the Head Start children in this study have maintained an ability level comparable to their nearest-neighbor peers.

This study examined the effects of a parent-implemented intervention on preschool children's development of letter-naming and phonological awareness skills. Six parent-child dyads with children enrolled in a Head Start Program in West Central Florida were selected to participate in the study. A multiple baseline across participants design was used to evaluate the impact of an intervention package that included activities focusing on: (1) using mnemonics to learn letter names and (2) developing phonological awareness of the onsets of words through parent questioning and feedback. Phonological awareness development was measured using the Dynamic Indicators of Basic Early Literacy Skills First Sound Fluency (DIBELS-FSF) and letter-naming ability was measured using the DIBELS Letter Knowledge (DIBELS-LK) probes. Results showed that five of the six students responded favorably to the intervention, increasing their growth rate on at least one of the two measures. The final child showed little change in trends across the phases. Additionally, data was collected regarding intervention integrity of intervention implementation as well as social validity, or the acceptance and usefulness, of the intervention. Intervention integrity data revealed that the majority of parents completed the intervention with high levels of fidelity, although variability across parents was noted. Social validity data indicated that the parents found the program helpful and effective. Implications for research and practice are discussed.

The swimming track start is a complex motor skill that utilizes asymmetric lower limb action. The purpose of this study was to explore whether it could be optimized by applying the commonly accepted view that there are asymmetries in the function and behaviors of the lower limbs. Initially, the study aimed to examine the relationship between various measures of lower limb asymmetry and the swimmers' preferences for forward foot placement in the swimming track start. Participants underwent a 7 week training period whereby both the left foot forward (LFF) and the right foot forward (RFF) track starts were practiced. The philosophy behind this training protocol was to ensure that participants received equal practice with the preferred and non-preferred stance so that a dominant stance, if it existed, could emerge. Consequently, the relationships between the dominant track start stance and the lower limb asymmetry measures could be determined more accurately. Participants were male (N=11) and female (N=11) swimmers, aged 12-16 years, from the UWA-Uniswim National Age Squad. Kinetic and kinematic data were collected for the track start prior to and following the 7 week training intervention. The intervention was finished when a participant had completed approximately 14 dive sessions where both the LFF and RFF track starts were practiced. The performance criterion measure was time to 5 m. Despite significant differences in vertical force and velocity contributions following the intervention, time to 5 m did not improve for either the LFF or the RFF track start. Four different measures of lower limb asymmetry were collected, including footedness, the preferred track start stance, and the dominant take-off limb for the unilateral and bilateral counter-movement jump (CMJ). Sixteen of 22 participants displayed changes in their dominant track start stance. Eleven participants showed biases for one stance (6 for the LFF & 5 for the RFF), and 11 participants remained or became more symmetrical. Results indicated that the preferred track start stance was the only measure of asymmetry that was significantly related to track start performance (x2[2]= 6.71, p=.04 for pre-intervention & x2[2]=7.77, p=.02 for post-intervention). All other measures of lower limb asymmetry were shown to be unrelated to track start preference and performance. It was suggested that the 7 week training intervention did not provide a sufficient amount of time to see conclusive effects on 5 m time or to make conclusive comparisons between the dominant track start stance and measures of asymmetry. Since the preferred track start corresponded with better performance less than 50% of the time, it was suggested that swimmers and coaches experiment with different dive techniques to find the start which is most effective for them and spend more time on them during training.
