A case study in the e-assessment of statistics for non-specialists (2021)
Journal Article
Weir, I. S., Gwynllyw, D. R., & Henderson, K. L. (2021). A case study in the e-assessment of statistics for non-specialists. Journal of University Teaching and Learning Practice, 18(2), Article 5

The need to be able to choose, perform and interpret the results from appropriate statistical tests is ubiquitous in many STEM disciplines and beyond. In this case study, we illustrate a learning and assessment approach that has been used successfull... Read More about A case study in the e-assessment of statistics for non-specialists.

The relative importance of invertebrate and microbial decomposition in a rainforest restoration project (2017)
Journal Article
Donald, J., Weir, I., Bonnett, S., Maxfield, P., & Ellwood, M. D. F. (2018). The relative importance of invertebrate and microbial decomposition in a rainforest restoration project. Restoration Ecology, 26(2), 220-226. https://doi.org/10.1111/rec.12553

© 2017 Society for Ecological Restoration Tropical rainforests are increasingly disturbed by human activities. While restoration projects often succeed in replacing tree cover, they rarely manage to restore soil function. Consequently, there is an ur...

© The Author 2015. We demonstrate how the DEWIS e-Assessment system may use embedded R code to facilitate the assessment of students' ability to perform involved statistical analyses. The R code has been written to emulate SPSS output and thus the st... Read More about Using DEWIS and R for multi-staged statistics e-Assessments.

Creating statistics e-assessments using Dewis with embedded R code (2016)
Journal Article
Weir, I., Gwynllyw, R., & Henderson, K. (2017). Creating statistics e-assessments using Dewis with embedded R code. MSOR Connections, 15(2), 51-59

We report on the creation of statistics e-assessments using the Dewis system with embedded R code. Dewis is a fully algorithmic open-source e-assessment system designed and developed at the University of the West of England, Bristol (UWE). Dewis’ abi...

Modelling vocabulary growth in a foreign language (2012)
Journal Article
Daller, M., Turlik, J., & Weir, I. Modelling vocabulary growth in a foreign language. Manuscript submitted for publication

Many studies in a variety of educational contexts show that learning curves are non-linear (e.g. Freedman 1987 for the development of story telling skills in the first language, De Keyser 1997 for the acquisition of morphosyntactic rules of an artifi...

The relationship between teenage 'binge' drinking, age of first alcohol consumption and intoxication (2008)
Journal Article
Afitska, N., Plant, M., Weir, I., Miller, P., & Plant, M. (2008). The relationship between teenage 'binge' drinking, age of first alcohol consumption and intoxication. Journal of Substance Use, 13(3), 205-218. https://doi.org/10.1080/14659890701740663

This paper is an investigation into the relationships between 'binge' drinking in adolescence, and ages of first drinking alcohol (beer, wine, spirits) and of first intoxication. These relationships are examined using data collected as part of the UK... Read More about The relationship between teenage 'binge' drinking, age of first alcohol consumption and intoxication.

A conditional autoregressive Gaussian process for irregularly spaced multivariate data with application to modelling large sets of binary data (2002)
Journal Article
