Relative Contributions of Prekindergarten and Kindergarten to Children's Literacy and Mathematics Skills

Research Findings: A difficulty for developmental researchers is disambiguating children's general maturation from the influence of schooling. In this study, we use a natural experiment to examine the influence of prekindergarten and kindergarten schooling experiences on the development of literacy and mathematics. Children (n = 60) whose birthdates fell within 2 months of the state-determined cutoff date for prekindergarten and kindergarten entry were administered 4 subtests of the Woodcock–Johnson III Tests of Achievement in the fall and spring of the school year. Using hierarchical linear modeling coupled with propensity score matching, we found that children who were starting kindergarten and who had prior experience in prekindergarten had higher scores on measures of phonological awareness, early reading, and mathematics skills than did children who had not attended prekindergarten previously, even though they were essentially the same age. Fall vocabulary scores did not differ in relation to whether children had prekindergarten experience. In addition, although children who attended kindergarten as well as those who attended prekindergarten exhibited growth on all measures during the school year, children who attended kindergarten demonstrated greater gains in early reading and vocabulary during the school year. Practice or Policy: These findings highlight the potential of early schooling processes to facilitate children's intellectual growth.     

Effect of short-term application of kinesio tape on the flexion-relaxation phenomenon,trunk postural control and trunk repositioning in healthy females

This study was designed to investigate the potential effects of kinesio tape on the flexion-relaxation phenomenon, trunk postural control and trunk position sense when applied for a short period (30 min) to the low back of healthy female participants. Twenty-four participants were assigned to one of two groups: kinesio tape applied in either the recommended stretched or non-stretched (control) manner over the low back. Tests were performed at three time points (pre-tape, with tape, post-tape) to assess low-back muscle flexion-relaxation, position sense during active trunk repositioning and trunk postural control during seated balance. Results demonstrated that wearing kinesio tape did not affect the angle at which the erector spinae muscles became silent during trunk flexion (flexion-relaxation). Trunk repositioning error increased when wearing kinesio tape in both the stretched and non-stretched manner, and this increased error persisted after the tape was removed. Seated balance control improved when wearing kinesio tape in both the stretched and non-stretched manner, and these improvements persisted after the tape was removed. In conclusion, these findings do not support the general suggestions that short-term use of kinesio tape on the low-back region alter low-back muscle activation and enhance tasks related to proprioception, at least under these taping conditions in a group of healthy females.     

Randomized trial of a statewide home visiting program to prevent child abuse: impact in reducing parental risk factors

OBJECTIVES: To assess the impact of a home visiting program in reducing malleable parental risk factors for child abuse in families of newborns identified, through population-based screening, as at-risk of child abuse. METHODS: This randomized trial focused on Healthy Start Program (HSP) sites operated by three community-based organizations on Oahu, HI, USA. From 11/94 to 12/95, 643 families were enrolled and randomly assigned to intervention and control groups. Mothers in both groups were interviewed annually for 3 years (88% follow-up each year) to measure mental health, substance use, and partner violence. HSP records were reviewed to measure home visiting services provided. Home visitors were surveyed annually to measure their perceived competence. RESULTS: Malleable parental risks for child abuse were common at baseline. There was no significant overall program effect on any risk or on at-risk mothers' desire for and use of community services to address risks. There was a significant reduction in one measure of poor mental health at one agency and a significant reduction in maternal problem alcohol use and repeated incidents of physical partner violence for families receiving > or =75% of visits called for in the model. Home visitors often failed to recognize parental risks and seldom linked families with community resources. HSP training programs were under-developed in preparing staff to address risks and to link families with community resources. CONCLUSIONS: Overall, the home visiting program did not reduce major risk factors for child abuse that made families eligible for service. Research is needed to develop and test strategies to improve home visiting effectiveness in reducing parental risks for child abuse.     

Pre‐schoolers,print and storybooks: an observational study using eye movement analysis

This study used eye‐gaze analysis to determine the extent to which pre‐school children visually attended to print when looking at two storybooks, to contrast visual attention to print for a print‐salient versus a picture‐salient storybook, and to study individual differences in pre‐schoolers' visual preferences. Results indicated that pre‐school children infrequently attended to print: in a traditional picture‐salient storybook, 2.7% of their fixations focused on print and 2.5% of their time was spent looking in regions of print. The children fixated more frequently on print and spent more time looking in print regions when reading a print‐salient storybook, within which 7% of fixations focused on print and 6% of time was spent in print zones. Effect size estimates showed this difference to be consistent with a very large effect. Little variation in visual attention to print was observed across the ten children, and children's alphabet knowledge was not associated with the variance in children's visual attention to print. Educational implications are discussed.     

How Much Have They Retained? Making Unseen Concepts Seen in a Freshman Electromagnetism Course at MIT

The introductory freshmen electromagnetism course at MIT has been taught since 2000 using a studio physics format entitled TEAL—Technology Enabled Active Learning. TEAL has created a collaborative, hands-on environment where students carry out desktop experiments, submit web-based assignments, and have access to a host of visualizations and simulations. These learning tools help them visualize unseen electromagnetic concepts and develop stronger intuition about related phenomena. A previous study has shown that students who took the course in the TEAL format (the experimental group) gained significantly better conceptual understanding than those who took it in the traditional lecture-recitation format (the control group). The present longitudinal study focuses on the extent to which these two research groups (experimental and control) retain conceptual understanding about a year to 18 months after finishing the course. It also examines students attitudes about whether the teaching format (TEAL or traditional) contributes to their learning in advanced courses. Our research has indicated that the long-term effect of the TEAL course on students’ retention of concepts was significantly stronger than that of the traditional course. This research is significant because it documents the long-term cognitive and affective impact of the TEAL studio physics format on learning outcomes of MIT students.

Reading against all odds: a pilot study of two deaf students with dyslexia

Learning to read and write is a challenge for most deaf children due to their limited experiences with, and access to, spoken language. In the case of deaf students who have difficulty processing visual print, literacy becomes an even greater challenge. The study piloted an intervention procedure that incorporated the principles of automaticity, repetition, functional vocabulary, and a positive teacher-student relationship as recommended in programs for struggling readers and adapted them to the needs of two deaf high school students with dyslexia in an American Sign Language-English bilingual program. The findings reveal gains in reading ability on the formal measures, though not more than would be expected over a 6-month period simply due to development. The real improvements were noted in the students' attitudes toward literacy, improved social interaction, and increased self-confidence.     

Impact of a statewide home visiting program on parenting and on child health and development

OBJECTIVES: To assess the impact of a voluntary, paraprofessional home visiting program on promoting child health and development and maternal parenting knowledge, attitudes, and behaviors. METHODS: This collaborative, experimental study of 6 Healthy Families Alaska (HFAK) programs enrolled 325 families from 1/00 to 7/01, randomly assigned them to HFAK and control groups, interviewed mothers at baseline, and followed families until children were 2 years old (85% follow-up). Child outcomes included health care use, development and behavior. Parent outcomes included knowledge of infant development, parenting attitudes, quality of the home environment, and parent-child interaction. HFAK records were reviewed to measure home visiting services. Home visitors were surveyed to measure knowledge, perceived effectiveness and perceived training adequacy. RESULTS: There was no overall impact on child health, but HFAK group children had more favorable developmental and behavioral outcomes. HFAK and control mothers had similar parenting outcomes except that HFAK mothers had greater parenting self-efficacy (35.1 vs. 34.6 based on the Teti Self-Efficacy Scale, p<.05). Fewer HFAK families had a poor home environment for learning (20% vs. 31%, p<.001). HFAK families were more likely to use center-based parenting services (48% vs. 39%, p<.05). The impact was greater for families with lower baseline risk (Family Stress Checklist scores<45). There was little evidence of efficacy for families with a higher dose of service. CONCLUSIONS: The program promoted child development and reduced problem behaviors at 2 years. Impact could be strengthened by improving home visitor effectiveness in promoting effective parenting. Future research is needed to determine whether short-term benefits are sustained.
