Researchers across many fields have called for greater attention to heterogeneity of treatment effects--shifting focus from the average effect to variation in effects between different treatments, studies, or subgroups. True heterogeneity is important, but many reports of heterogeneity have proved to be false, non-replicable, or exaggerated. In…

Objective: Explicit instructions to students to use the index finger to trace out specified elements of mathematics worked examples have been shown to improve mathematics learning outcomes; however, there is limited research on whether the magnitude of tracing actions impacts these outcomes. Method: Using an experimental design, 34 adults were…

Item response tree (IRTree) models are a flexible framework to control self-reported trait measurements for response styles. To this end, IRTree models decompose the responses to rating items into sub-decisions, which are assumed to be made on the basis of either the trait being measured or a response style, whereby the effects of such person…

Within intelligent tutoring systems, considerable research has investigated hints, including how to generate data-driven hints, what hint content to present, and when to provide hints for optimal learning outcomes. However, less attention has been paid to "how" hints are presented. In this paper, we propose a new hint delivery mechanism…

Aptitude-treatment interaction (ATI) research is of both theoretical and practical interest to second language (L2) learning, since it provides insights into the processes linking learner-internal individual difference factors and learner-external contextual variables including instructional approach--variables that jointly determine L2 outcomes.…

The development of the revolution era 4.0 which increasingly rapidly demands the wider community to have the ability to think creatively mathematically. One effort to improve the ability to think creatively is through quality education. Quality education can be improved through to train thinking using the right learning model. This study aims to…

The amount of information that students successfully learn and later recall from each intervention session is limited and is called the acquisition rate (AR). Research has consistently supported the effects of modifying intervention set sizes with AR data, but research with AR is in its infancy. The current study compared the relationship between…

Because of the importance of teaching reading comprehension to struggling young readers and the infrequency with which it has been implemented and evaluated, we designed a comprehensive first-grade reading comprehension program. We conducted a component analysis of the program's decoding/fluency and reading comprehension dimensions (DF and COMP),…

This article draws on new materialism, especially the work of Karen Barad, in order to explore curious encounters and intra-actions within the context of a Norwegian kindergarten. The article argues that intra-actions between both human and non-human agents can potentiate forms of learning as well as forms of knowledge that can be neither…

Drawing upon four years of research within a social design experiment, we focus on how teacher learning can be supported in designed environments that are organized around robust views of learning, culture, and equity. We illustrate both the possibility and difficulty of helping teachers disrupt the default teaching scripts that privilege…

For typically developing (TD) children, the home literacy environment (HLE) impacts reading competence, yet few studies have explored the HLE of children with autism spectrum disorders (ASD). We collected information about the HLE of children aged 7-13 with ASD and their TD peers via a parental questionnaire and examined whether there were any…

Based on data from a single institution, this study estimates the effect of having a female instructor, the effects of measures of self-efficacy, and the interaction effects of measures of self-efficacy and having a female instructor on female and male student grade performance. Self-efficacy for academic achievement, self-regulated learning,…

This paper provides an overview and update on my PhD research project which focuses on integrating learning styles into adaptive e-learning system. The project, firstly, aims to develop a system to classify students' learning styles through their online learning behaviour. This will be followed by a study on the complex relationship between…

Language learning strategies (LLSs) are believed to be influenced by individual differences as well as environmental and contextual factors. Therefore, the effective use of LLSs is determined by various factors, including both learning and learner variables. This dynamic and complex nature of LLSs renders it appropriate to use a qualitative…

This study examines an interactional view on teaching mathematics, whereby meaning is co-produced with the students through a process of negotiation. Further, teaching is viewed from a symbolic interactionism perspective, allowing the analysis to focus on the teacher's role in the negotiation of meaning. Using methods inspired by grounded theory,…
