Adding a self-regulation intervention to a school readiness programme can improve self-regulation, early academic skills and school readiness in children at higher risk for later school difficulties, according to the results of a study published in Early Childhood Research Quarterly.
Robert J Duncan and colleagues looked at the effect of adding a self-regulation intervention to the Bridge to Kindergarten (B2K) programme – a three-week summer school-readiness programme – in the US state of Oregon. The B2K programme is aimed at children with no prior preschool experience, and therefore considered to be at risk for later school difficulties.
Children from three to five years old were randomly assigned to either a control group (B2K only) or the intervention group (B2K plus intervention). Children in the intervention group received two 20- to 30-minute sessions per week, involving movement and music-based games that encouraged them to practise self-regulation skills.
Results from this randomised controlled trial indicated that children who received the intervention scored higher on measures of self-regulation than children who participated in the B2K programme alone. There were no significant effects on maths or literacy at the end of the programme. However, four months into kindergarten, children from the intervention group showed increased growth in self-regulation, maths and literacy compared to expected development.

A study, published in The Journal of Child Psychology and Psychiatry, evaluates the effectiveness of a parent-delivered language programme on pre-school children’s language and emerging reading skills.
Kelly Burgoyne and colleagues conducted a randomised controlled trial with 208 pre-school children (mean age 3 years, 1 month) and their parents living in socially diverse areas of the UK. Children and parents received either an oral language programme or an active control programme targeting motor skills. Parents delivered the 20-minute sessions to their child at home every day over 30 weeks. Children were assessed at pre-test, post-test, and 6 months after post-test on measures of language and motor skills. Early literacy skills (letter-sound knowledge, phoneme awareness and regular and irregular word reading) were assessed at 6 months after post-test only, as children were non-readers at pre- and post-test.
Children who received the language programme made larger gains in language skills (effect size = +0.21) and narrative skills (effect size = +0.36) at post-test than those children who received the active control programme, and these results were maintained six months later. Improvements were also seen in letter-sound knowledge (effect size = +0.42) and regular word reading (effect size = +0.35). No evidence was found that the control programme improved motor skills.

A randomised controlled trial, conducted by Silke Fricke and colleagues, looked at the effect of an oral language intervention and compared the extent to which a 30-week programme beginning in nursery and continuing for 20 weeks in Reception was more effective than delivering a 20-week programme starting in Reception.
Children from 34 nurseries in the UK were randomly allocated to a 30-week intervention (n= 132), a 20-week intervention (n=133), or an untreated waiting control group (n=129). Allocation was minimized for gender, age and verbal skills. The children in the 30-week intervention group received the Nuffield Early Language Intervention programme for 10 weeks in nursery and continued for 20 weeks in Reception. The 20-week intervention group received only the final 20 weeks of the intervention, beginning when they entered primary school. The control group received their usual schooling.
Children in both the 20- and 30-week programme intervention groups showed greater improvement in oral language skills on measures including the CELF Expressive Vocabulary and CELF Sentence Structure subtests, and the Information Score from the Renfrew Action Picture Test, compared to children in the control group (effect size for the 20-week programme = +0.21; effect size for the 30-week programme = +0.30). However, there was no evidence to suggest that either programme improved early literacy or reading comprehension skills.

A new study published in Child Development has found positive results for an intervention designed to improve early language and pre-literacy skills in children in Denmark.
Dorthe Bleses and colleagues conducted a randomised controlled trial of three variations of SPELL (Structured Preschool Efforts in Language and Literacy), to evaluate to what extent the intervention increased children’s language and pre-literacy skills compared to business as usual. SPELL, which is a Danish version of an existing programme, Read it Again-PreK!, is a 20-week storybook-based intervention for children aged three- to six-years-old. Twice a week, children receive 30-minute lessons in small groups which include a before, during, and after reading activity to address the lesson’s objectives, which is delivered via an iPad-based digital learning technology.
For the trial, 6,483 children from 144 childcare settings were randomly assigned to one of three variations of SPELL, or continued with business as usual. Pre- to post-test comparisons showed an impact of all three interventions for literacy skills (effect sizes = +0.21 to +0.27) but not language skills (+0.04 to +0.16), with little difference among the three variations.

A study published in the Journal of Child Psychology and Psychiatry examines whether language outcomes for low socio-economic status (SES) children can be improved by encouraging contingent talk (how often the parent talks about objects in the child’s current focus of attention) through a low-intensity intervention.
In a randomised controlled trial with high- and low-SES families, 142 children aged 11 months and their parents were randomly allocated to either a contingent talk intervention or a dental health control. Families in the intervention watched a video about contingent talk and were asked to practice it for 15 minutes a day for a month. Families were visited in their homes twice when children were 11, 12, 18 and 24 months. Questionnaires were also collected by mail at 15 months. Parent communication was assessed at 11 months (baseline) and after one month. Infant communication was assessed at baseline, 12, 15, 18 and 24 months.
At baseline, the amount of contingent talk children hear is found to be associated with SES, with lower-SES parents engaging in less contingent talk. At post-test (when children were 12 months old) all parents who had taken part in the intervention engaged in more contingent talk, regardless of their socioeconomic status. Lower-SES parents in the intervention group reported that their children produced more words at 15 and 18 months. However, effects of the intervention didn’t persist at 24 months. So while parents’ contingent talk is increased through the intervention, and this is effective in promoting vocabulary growth for lower-SES infants in the short term, these effects are not long-lasting. The study concludes that follow-up interventions may be necessary to produce benefits lasting to school entry.

While the effects of preschool programmes have often been studied, it is less common to find studies examining the effects of programme duration on student learning. Annemarie Hindman and Barbara Wasik from Temple University, Pennsylvania, examined the effects of providing one year versus two years of the teacher professional development programme Exceptional Coaching for Early Language and Literacy (ExCELL) on the language development and learning outcomes of three- and four-year-old children in the US preschool programme, Head Start.
ExCELL provides teachers with individualised coaching by providing a background in the concepts underlying preschoolers’ language and vocabulary development, evolving into ways to develop these skills in the classroom. Teachers are provided with curriculum materials and an academic year of month-long coaching, each month cycling through a group workshop, a coach modelling targeted techniques in the classroom, the teacher using these techniques independently, and finally the coach observing the teacher and providing feedback.
In the present study, 159 four-year-old children in Head Start experienced either one year (n=88), starting at age four, or two years (n=71), starting at age three, with teachers using ExCELL. Children were in 10 Head Start centres in the urban Northeastern United States in adjacent neighbourhoods with demographically similar populations. Almost all students and teachers were African-American and all were native English speakers.
At four years old, children were tested in the spring and autumn using standardised tests measuring vocabulary, sound awareness, and alphabet knowledge. Results showed that although the four-year-olds who had already received one year of the programme entered their second year with stronger vocabulary, phonemic awareness, and alphabet knowledge than their peers who had not yet experienced the programme, by the year’s end, these peers had caught up to them. The authors state that these findings suggest that ExCELL is most effectively taught in the second year of preschool.
