Individual Participant Data Meta-analysis of the Impact of Educational Interventions on Pupils Eligible for Free School Meals (2021)
Journal Article
Ashraf, B., Singh, A., Uwimpuhwe, G., Higgins, S., & Kasim, A. (2021). Individual Participant Data Meta-analysis of the Impact of Educational Interventions on Pupils Eligible for Free School Meals. British Educational Research Journal, 47(6), 1675-1699. https://doi.org/10.1002/berj.3749

Meta-analysis is the synthesis of findings from research projects, which enables an estimate of the average or pooled effect across various studies. This study presents findings from the intention to treat analysis for a series of educational evaluat...

Multisite educational trials: estimating the effect size and its confidence intervals (2021)
Journal Article
Singh, A., Uwimpuhwe, G., Li, M., Einbeck, J., Higgins, S., & Kasim, A. (2022). Multisite educational trials: estimating the effect size and its confidence intervals. International Journal of Research & Method in Education, 45(1), 18-38. https://doi.org/10.1080/1743727x.2021.1882416

In education, multisite trials involve randomisation of pupils into intervention and comparison groups within schools. Most analytical models in multisite educational trials ignore that the impact of an intervention may be school dependent. This stud...

Application of Bayesian posterior probabilistic inference in educational trials (2020)
Journal Article
Uwimpuhwe, G., Singh, A., Higgins, S., & Kasim, A. (2021). Application of Bayesian posterior probabilistic inference in educational trials. International Journal of Research & Method in Education, 44(5), 533-554. https://doi.org/10.1080/1743727x.2020.1856067

Educational researchers advocate the use of an effect size and its confidence interval to assess the effectiveness of interventions instead of relying on a p-value, which has been blamed for lack of reproducibility of research findings and the misuse...

Latent Class Evaluation in Educational Trials: What Percentage of Children Benefits from an Intervention? (2020)
Journal Article
Uwimpuhwe, G., Singh, A., Higgins, S., Coux, M., Xiao, Z., Shkedy, Z., & Kasim, A. (2022). Latent Class Evaluation in Educational Trials: What Percentage of Children Benefits from an Intervention?. The Journal of Experimental Education, 90(2), 404-418. https://doi.org/10.1080/00220973.2020.1767021

Educational stakeholders are keen to know the magnitude and importance of different interventions. However, the way evidence is communicated to support understanding of the effectiveness of an intervention is controversial. Typically studies in educa...

An Empirical Unravelling of Lord’s Paradox (2017)
Journal Article
Xiao, Z., Higgins, S., & Kasim, A. (2019). An Empirical Unravelling of Lord’s Paradox. The Journal of Experimental Education, 87(1), 17-32. https://doi.org/10.1080/00220973.2017.1380591

Lord's Paradox occurs when a continuous covariate is statistically controlled for and the relationship between a continuous outcome and group status indicator changes in both magnitude and direction. This phenomenon poses a challenge to the notion of... Read More about An Empirical Unravelling of Lord’s Paradox.

A longitudinal study of the association between inattention, hyperactivity and impulsivity and children's academic attainment at age 11 (2016)
Journal Article
Merrell, C., Sayal, K., Tymms, P., & Kasim, A. (2017). A longitudinal study of the association between inattention, hyperactivity and impulsivity and children's academic attainment at age 11. Learning and Individual Differences, 53, 156-161. https://doi.org/10.1016/j.lindif.2016.04.003

Background The link between inattention and hyperactivity/impulsivity and poor academic outcomes is well established. Children with mild difficulties can go unnoticed yet may be at risk of poor academic outcomes. Aims To investigate the link between...

Same Difference? Understanding Variation in the Estimation of Effect Sizes from Educational Trials (2016)
Journal Article
Xiao, Z., Higgins, S., & Kasim, A. (2016). Same Difference? Understanding Variation in the Estimation of Effect Sizes from Educational Trials. International Journal of Educational Research, 77, 1-14. https://doi.org/10.1016/j.ijer.2016.02.001

By applying four analytic models with comparable outcomes and covariates to a dataset of 20 outcomes from 17 educational trials, we found results closely matching in well-powered studies without serious implementation problems. The interventions and... Read More about Same Difference? Understanding Variation in the Estimation of Effect Sizes from Educational Trials.
