A study published in Economics of Education Review looks at the evidence from the extended school day (ESD) programme in Florida to determine whether pupils benefit from longer school days.
In 2012, Florida introduced the ESD programme, increasing the length of the school day by an hour in the lowest-performing elementary (primary) schools in order to provide additional reading lessons. The lessons had to be based on research, adapted for pupil ability, and include phonemic awareness, phonics, fluency, vocabulary and comprehension. Schools were selected using school-level reading accountability measures. For this study, David Figlio and colleagues looked at reading scores for all pupils in Florida between grades 3 and 10 (Years 4 and 11) using school administrative data from 2005–06 and 2012–13, and employed a regression discontinuity design to estimate the effect of lengthening the school day, looking at the different performance of schools either side of the cut-off point.
Results indicated that the additional one hour of reading lessons had a positive effect on pupils’ reading achievement. ESD schools showed an improvement of +0.05 standard deviations on reading test scores in the first year. The annual cost of the ESD programme was $300,000-$400,000 per school, or $800 per pupil.

Reducing class size is often suggested as a way of improving pupil performance. However evidence from a new Campbell systematic review suggests that reducing class size has at best only a very small effect.
The review summarises findings from relevant studies that measured the effects of class size on academic achievement. A total of 127 studies were analysed, including 45 studies that used data from the US Student Teacher Achievement Ratio (STAR) programme that reduced class sizes substantially in kindergarten to grade 3 (Years 1 to Year 4). However only ten studies, including four of the STAR programme, could be included in the meta-analysis.
Their analysis focused on effects on maths and reading and found a small positive effect of reducing class size on pupils’ reading achievement and a negative, but statistically insignificant, effect on maths. For reading, the weighted average effect size was +0.11, and the weighted average effect size for maths was -0.03.
For the four studies using data from the STAR programme, the researchers found a positive effect of smaller class sizes for both reading and maths. However, the average effect sizes were still very small and do not change the overall finding.

A recent meta-analysis showed that paper-based reading yields better outcomes in reading comprehension than digital reading. In an article appearing in Educational Research Review, Pablo Delgato and colleagues from Spain and Israel analysed 54 studies from 2000–2017 comparing the reading comprehension outcomes of comparable paper and digital texts. They examined if one medium has an advantage over the other for reading outcomes, and what factors contribute to any differences found.
Results showed that paper text has an advantage over digital text (effect size=+0.21). Influencing factors favouring paper text include reading under time limitations, text type (informational or informational plus narrative), and publication year—later publications showed increased advantages for paper reading than earlier publications.
While the authors do not advocate getting rid of digital texts given their convenience, cost advantages and pervasiveness, they reflect that these study findings should be considered when pupils are required to perform digitally-related tasks under time constraints.

An evaluation published in Educational Evaluation and Policy Analysis evaluates the impact of the Digital Conversion Initiative on pupil outcomes for one US school district in North Carolina.
The initiative provided laptop computers to every pupil from the fourth grade (Year 5) upwards, while also providing teachers with training on how to best use the technology in their lesson plans.
Marie Hull and Katherine Duch used administrative school data from 2005 to 2013 to determine the programme’s impact on maths and reading achievement for pupils in grades 4 to 8 (Years 5 to 9), as well as the impact of the programme on pupil behaviour. They compared the district’s data from before and after implementation, as well as data from neighbouring school districts without one-to-one programmes to determine the short- and medium-term effects.
Their results suggest there is potential for one-to-one laptop programmes to help improve pupil outcomes. They found that:
- Maths scores for pupils improved by 0.11 standard deviations in the short term and 0.13 standard deviations in the medium term.
- No significant change in reading scores in the short term, and mixed evidence of improvement in the medium term.
- Time spent on homework stayed constant.
- Pupils spent more of their homework time using a computer.

A meta-analysis, published in Review of Educational Research, examines how shared book reading affects the English language and literacy skills of young children learning English as an additional language (EAL)
Shared book reading involves an adult reading with one or more children, and is considered to be an effective practice for language and literacy development. It may also involve interactive practices such as dialogic reading techniques to engage children or reinforce specific ideas or words from the text.
For this meta-analysis, Lisa Fitton and colleagues identified 54 studies of shared reading interventions conducted in the US that met their inclusion criteria. The total number of participants across the studies was 3,989, with an average age of six.
Results revealed an overall positive effect of shared reading on EAL outcomes (effect size = +0.28). Children’s developmental status moderated this effect, with larger effect sizes found in studies including only typically developing children (+0.48) than in studies including only participants with developmental disorders (+0.17).

Several recent Best Evidence in Brief articles describe the positive effects on reading achievement of providing free vision screening and glasses to pupils who need them. Adding to the evidence showing that vision is one of the most important health outcomes for academic success, a recent study describes the results of one such programme, Florida Vision Quest.
Florida Vision Quest (FLVQ) is a programme designed to provide pupils in high-poverty schools with vision screening and free vision testing in a mobile vision clinic. If children are found to need glasses, they receive them at no charge. Two pairs are given to each child.
Within three school districts in Central Florida, elementary Title I schools were randomly assigned to one of three treatments: Full treatment (n=19), screen only (n=19), or control (n=38). Only pupils in grades 4 and 5 (Year 5 and 6) were involved in the study. Outcomes were determined for all pupils in those grades, not just those who needed glasses.
Findings showed there were significant positive effects on reading (Florida Comprehensive Achievement Tests, or FCAT) for schools that received the full treatment (effect size = +0.13) but not for those that received screening only. There were no effects for maths.
