Mixed-effects models are an analytic technique for modeling repeated measurement or nested data. This paper explains the logic of mixed-effects modeling and describes two examples of mixed-effects analyses using R. The intended audience of the paper is psychologists who specialize in cognitive development research. Therefore, the concepts and…

A vast amount of published scholarly literature is generated every day. Today, it is one of the biggest challenges for organisations to extract knowledge embedded in published scholarly literature for business and research applications. Application of text mining is gaining popularity among researchers and applications are growing exponentially in…

This case provides an account of the use of the repertory grid interview technique as one aspect of my PhD study. The doctoral thesis documented the development of a holistic approach to redesign an introductory programming course to enhance learning and teaching of object-oriented programming to novices. Starting with the premise that it is not…

This dissertation proposal begins with a discussion about how the education of game programmers was not meeting the needs of the game industry. With this problem identified, this study proceeded to verify the existence of disparities of current game programming curricula. The findings from the literature review were able to: (a) justify the need…

This article describes how research methodologies were modified and integrated during the doctoral research conducted by the first author under the supervision of the second author. The research project concerned trying to understand why teachers do or don't use "Jeliot", a program animation system designed to facilitate teaching and learning of…

Education research rarely lends itself to large scale experimental research and true randomization, leaving the researcher to quasi-experimental designs. The problem with quasi-experimental research is that underlying factors may impact group selection and lead to potentially biased results. One way to minimize the impact of non-randomization is…

The 7th International Conference on Education Data Mining held on July 4th-7th, 2014, at the Institute of Education, London, UK is the leading international forum for high-quality research that mines large data sets in order to answer educational research questions that shed light on the learning process. These data sets may come from the traces…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
