  • PLS Description Determining how to provide the best instruction to support children’s reading comprehension requires an understanding of how reading comprehension actually develops. To promote our understanding of this process, this review summarizes evidence from observations of the development of language and reading comprehension from the preschool years into school. The main outcome in this review is reading comprehension skills. Understanding the development of reading comprehension and its precursors can help us develop hypotheses about what effective instruction must comprise to facilitate well-functioning reading comprehension skills. These hypotheses can be tested in randomized controlled trials.

Mindfulness Based Stress Reduction is a group-based health promotion intervention to improve health and the way people deal with stress and life’s challenges. The core ingredient is mindfulness training through physical and mental exercises practiced daily for eight weeks. The mindful non-judgmental attitude of being present with what arises is practiced in the formal exercises and in everyday situations. This review assesses the effect of MBSR programs on outcome measures of mental and physical health, quality of life and social functioning in adults.

    PLAIN LANGUAGE SUMMARY

    The review in brief

    Despite growing support and increased rate of which trauma‐informed approaches are being promoted and implemented in schools, evidence to support this approach is lacking.

    What is this review about?

    Exposure to different types of trauma have been associated with varying types and complexity of adverse outcomes, including adverse effects on cognitive functioning, attention, memory, academic performance, and school‐related behaviors. Given the growing research on trauma and increased knowledge about the prevalence, consequences and costs associated with trauma, there have been increased efforts at the local, state and federal levels to make systems “trauma‐informed” (Lang, Campbell, & Vanerploeg, 2015). While the intent of creating trauma‐informed approaches in schools is a noble one, relatively little is known about the benefits, costs, and how trauma‐informed approaches are being defined and evaluated (Berliner & Kolko, 2016). Adopting a trauma‐informed approach in a complex system such as a school building or district is a time consuming and potentially costly endeavor and thus it is important to assess the effects of this approach to inform policy and practice.

    This aim of this review was to assess trauma‐informed approaches in schools on trauma symptoms/mental health, academic performance, behavior, and socioemotional functioning. Trauma‐informed approaches include programs, organizations, or systems that realize the impact of trauma, recognize the symptoms of trauma, respond by integrating knowledge about trauma policies and practices, and seeks to reduce retraumatization. At least two of the three key elements of a trauma‐informed approach must have been present: Workforce development, trauma‐focused services, and organizational environment and practices, which differ from trauma‐specific interventions designed to treat or otherwise address the impact/symptoms of trauma and facilitate healing.

    What is the aim of this review?

    This Campbell systematic review sought to examine the effects trauma‐informed schools on trauma symptoms/mental health, academic performance, behavior, and socioemotional functioning. Although we conducted a comprehensive search to find studies testing trauma‐informed approaches in schools, no studies met the inclusion criteria.

    What are the main findings of this review?

    No studies met criteria for this review, indicating that there is a lack of evidence of trauma‐informed approaches in schools.

    What do the findings of this review mean?

    Despite widespread support and growing adoption of trauma‐informed approaches in schools across the globe, we found no studies to provide good evidence to suggest that this approach is effective in achieving the stated goals. Given the degree to which trauma‐informed approaches are being adopted in schools across the US and other countries, it is important that the effects of these programs be assessed.

    How up‐to‐date is this review?

    The review authors searched for studies June through September, 2017.

  • PLS Description The No Excuses charter school model focuses heavily on high academic expectations, rigid and consistent discipline, extended instructional time, intensive teacher training, and increased parental involvement. This review examines the effect of No Excuses charter schools on math and literacy achievement. On average, No Excuses charter schools are associated with greater student gains on standardized measures of math and literacy achievement when compared to traditional public schools—with higher gains for math.

Improved sanitation and hygiene reduce diarrhoea, but adoption remains a challenge.This review assesses the evidence for two questions: (1) how effective are different approaches to promote handwashing and sanitation behaviour change; and (2) what factors influence the implementation of these approaches?
