Many studies have been conducted to examine the impact for pupils of later school start times, some of which can be found in previous issues of Best Evidence in Brief. This Campbell systematic review summarises the findings from 17 studies to examine the evidence on the impact of later school start times on pupils’ mental health and academic performance.
The studies included in the review were randomised controlled trials, controlled before-and-after studies and interrupted time series studies with data for pupils aged 13 to 19 and that compared different school start times. The studies reported on 11 interventions in six countries, with a total of almost 300,000 pupils.
The main results of the review suggest that later school starts may be associated with positive academic benefits and psychosocial outcomes. Later school start times also appear to be associated with an increase in the amount of sleep children get. Effect sizes ranged from +0.38 to +2.39, equivalent to an extra 30 minutes to 2 hours of sleep each night. However, the researchers point out that, overall, the quality of the body of evidence is very low, and so the effects of later school start times cannot be determined with any confidence.

This Campbell Systematic Review examined the impact of interventions to reduce exclusion from school. School exclusion, also known as suspension, involves the removal of pupils from regular teaching for a period during which they are not allowed to be present at school. In some extreme cases, the pupil is not allowed to come back to the same school (expulsion).
The review summarised 37 studies, reporting 38 interventions’ effect sizes. Most studies were from the US (n=33) and the UK (n=3). All of them were randomised controlled trials.
The evidence suggested that school-based interventions are effective at reducing school exclusion during the first six months after the intervention (effect size =+0.30), but that this effect is not sustained. Some specific types of interventions showed more promising results than others. Of the nine different types of school-based interventions included in the review, four types (enhancement of academic skills, counselling, mentoring/monitoring and skills training for teachers) showed positive results in reducing exclusion. However, based on the number of studies involved, the researchers suggest that results must be treated with caution.

A systematic review published by the Campbell Collaboration summarises the research on the correlation between reading-related preschool predictors, such as code-related skills and linguistic comprehension, and later reading comprehension skills.
Sixty-four longitudinal studies met the eligibility criteria for the review. These studies spanned 1986 to 2016 and were mostly carried out in the US, Europe and Australia. Overall, the findings of the review found that code-related skills (rhyme awareness, phoneme awareness, letter knowledge and rapid automatised naming) are most important for reading comprehension in beginning readers, but linguistic comprehension (grammar and vocabulary) gradually takes over as children become older. All predictors, except for non-word repetition, were moderately to strongly correlated with later reading comprehension. Non-word repetition had only a weak to moderate correlation to later reading comprehension ability.
These results suggest a need for a broad focus on language skills in preschool-age children in order to establish a strong foundation for reading comprehension.

Ada Chukwudozie and Howard White at The Campbell Collaboration have prepared a new summary of a previously published systematic review of teacher classroom management practices.
The review examined the effects of teacher classroom management programmes on disruptive or aggressive pupil behaviour and sought to identify which management components were most effective. Examples of the classroom management programmes included COMP (Classroom Organization and Management Program) and the Good Behaviour Game.
A total of 12 studies were included in the review. These studies reported on public school general education classes with pupils from Kindergarten to 12th grade (Years 1 to 13). Effectiveness studies had to use a valid experimental or quasi-experimental design with control groups to be included in the review.
According to the summary, multi-component classroom management programmes had a significant positive effect in decreasing aggressive or problematic behaviour in the classroom. Results showed that pupils in the treatment classrooms in all 12 studies reviewed showed less disruptive or problematic behaviors when compared to pupils in control classrooms without the intervention.
The summary notes that it was not possible to make any conclusions regarding which components of the management programmes were most effective due to small sample size and lack of information reported in the studies reviewed.

This Campbell systematic review examines the effectiveness of mindfulness-based interventions (MBIs) implemented in school settings on cognition, behaviour, socio-emotional outcomes and academic achievement. MBIs are interventions that use a mindfulness component, broadly defined as “paying attention in a particular way: on purpose, in the present moment, non-judgmentally”, and is often combined with yoga, cognitive-behavioural strategies, or relaxation-skills training.
A total of 61 studies are included in the review, but only the 35 randomised or quasi-experimental studies are used in the meta-analysis, with a total of 6,207 pupil participants. Most of the studies were carried out in schools in the US (74%), with some in Asia (5%), Europe (16%) and Canada (5%). The interventions ranged in duration (4–28 weeks), number of sessions (6–125 sessions) and frequency of meetings (once every two weeks to five times a week).
The findings show that MBIs in schools have a small positive effect on cognitive outcomes and socio-emotional outcomes, but do not improve behaviour or academic achievement. There was little heterogeneity for all outcomes, apart from behavioural outcomes, suggesting that the interventions produced similar results across studies on cognitive, socio-emotional and academic outcomes, despite the interventions being quite diverse. Overall, Brandy Maynard and colleagues find a lack of support at post-test to indicate that the positive effects on cognitive and socio-emotional outcomes then translate into positive outcomes on behaviour and academic achievement.
