Complex data structures are ubiquitous in psychological research, especially in educational settings. In the context of randomized controlled trials, students are nested in classrooms but may be cross-classified by other units, such as small groups. Furthermore, in many cases only some students may be nested within a unit while other students may…

Two approaches to causal inference in the presence of non-random assignment are presented: The Propensity Score approach which pseudo-randomizes by balancing groups on observed propensity to be in treatment, and the Endogenous Treatment Effects approach which utilizes systems of equations to explicitly model selection into treatment. The three…

Given the significance of boredom and its detrimental effects on the English as a foreign language (EFL) students' academic achievements, this study utilised an exploratory sequential mixed-methods design to initially explore the boredom factors in EFL classes among a sample of 139 university students and then develop and validate the Precursors…

Feedback loop reasoning is an essential part of systems thinking, which includes the analysis and description of system behaviour and regulative measures. In feedback loops, every change can simultaneously represent a cause and an effect. Research on reasoning in feedback loops is limited to investigating students' existing mental models. This…

In this paper I study how school desegregation by race following "Brown v. Board of Education" affected White individuals' racial attitudes and politics in adulthood. I use geocoded nationwide data from the General Social Survey and differences-in-differences to identify causal impacts. Integration significantly reduced White…

Purpose: This paper results from an intervention study focusing on the relationship between visual representation used in teaching about pricing in economics and teaching-learning practices established in the classroom, with a focus on the affordance offered through the representations used. Method: Lessons were conducted with four upper secondary…

This paper reviews research on the design and effectiveness of preschools in the United States. Three randomized controlled trials that enrolled roughly 350 total children in demonstration studies during the 1960s and 1970s shape much of the current discussion of preschool. We examine what these studies and more recent ones based on random…

Using socio-scientific issues (SSI) in the science learning environment can promote student motivation to learn and make learning experiences more meaningful. Embedding model-based reasoning opportunities in science lessons can promote substantial science learning. However, how these both work together to promote science learning is a little…

Researchers commonly interpret effect sizes by applying benchmarks proposed by Jacob Cohen over a half century ago. However, effects that are small by Cohen's standards are large relative to the impacts of most field-based interventions. These benchmarks also fail to consider important differences in study features, program costs, and scalability.…

Religiosity has been positively linked with multiple measures of academic success, but it is unclear whether the "effect" of religiosity on academic outcomes is causal or spurious. One source of heterogeneity that may contribute to a child's level of religiosity and his/her academic success is family background. This paper is the first…

While weighing up the relative merits of the competing narratives of the Battle of Hastings that his department might present to Year 7, Matthew Stanford began to consider how the causal models that teachers introduce influence the causal arguments that students later go on to write. In this article, Stanford shows how such realisations informed…

In this paper, I study the causal relationship between violence and human capital accumulation. Due to a power vacuum left in conflict zones of Colombia after the 2016 peace agreement, large spikes in violence were reported in the municipalities of the country dominated by the rebel group FARC. I compare student test scores in municipalities that…

The proposed study aims to explore the relationship of multicultural distress with general stress symptoms and academic achievement of college students who attend a Minority-Serving Institution (MSI). Research suggests that students who identify as being from a racial or ethnic minority background are likely to experience multicultural distress.…

Several challenges faced by humanity, such as the world food problem, migration flows or climate change, are all taught about in geography courses worldwide. Behind these challenges are complex systems consisting of several interrelated causes and consequences. In order to better understand these highly complex geographical systems, a systems…
