Journal Article
Einbeck, J., Coolen-Maturi, T., Uwimpuhwe, G., & Singh, A. (online). A Comparison of Threshold-Free Measures for Assessing the Effectiveness of Educational Interventions. The Journal of Experimental Education, https://doi.org/10.1080/00220973.2024.2405738

The effectiveness of educational interventions has traditionally been evaluated using effect size measures which focus on a single feature of the distribution of the outcomes under intervention and control conditions: a (standardized) mean difference...

Zhang, Q., Uwimpuhwe, G., Vallis, D., Singh, A., Coolen-Maturi, T., & Einbeck, J. (2024). Elicitation of Priors for Intervention Effects in Educational Trial Data. In J. Einbeck, H. Maeng, E. Ogundimu, & K. Perrakis (Eds.), Developments in Statistical Modelling (28-33). Springer. https://doi.org/10.1007/978-3-031-65723-8_5

Effect sizes for educational interventions are commonly small, and hence decisions to re-grant efficacy trials (small trials with homogeneous populations under idealized conditions) as effectiveness trials (larger trials with heterogeneous population...

The Toolkit has localised versions in... Read More about The Teaching and Learning Toolkit: Communicating research evidence to inform decision‐making for policy and practice in education.

Sequential multiple assignment randomized trial studies should report all key components: a systematic review (2021)
Journal Article
Bigirumurame, T., Uwimpuhwe, G., & Wason, J. (2022). Sequential multiple assignment randomized trial studies should report all key components: a systematic review. Journal of Clinical Epidemiology, 142, 152-160. https://doi.org/10.1016/j.jclinepi.2021.11.007

Objective
Sequential Multiple Assignment Randomized Trial (SMART) designs allow multiple randomizations of participants; this allows assessment of stage-specific questions (individual randomizations) and adaptive interventions (i.e. treatment strate...

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...

Background Poor performance in the 5‐chair stand test (5‐CST) indicates reduced lower limb muscle strength. The 5‐CST has been recommended for use in the initial assessment of sarcopenia, the accelerated loss of muscle strength and mass. In order to...
