Ethical decision-making and ethical behavior are an essential focus of training for students who wish to pursue careers in behavior analysis. In addition to education and training mandates by the Behavior Analyst Certification Board, universities that offer a Verified Course Sequence are required to teach and maintain ethical behavior in students.…

Analysis of consistent Zearn Math users and a comparable group of non-users in District of Columbia Public Schools (DCPS) shows that students who used Zearn Math consistently had higher levels of academic growth than similar students with low- or no-usage. This analysis used two quasi-experimental methods, Coarsened Exact Matching (CEM) and fixed…

Causal inference regarding a hypothesized mediation mechanism relies on the assumptions that there are no omitted pretreatment confounders (i.e., confounders preceding the treatment) of the treatment-mediator, treatment-outcome, and mediator-outcome relationships, and there are no posttreatment confounders (i.e., confounders affected by the…

Educational video games can engage students in authentic STEM practices, which often involve visual representations. Specifically, because most interactions within video games are mediated through visual representations, video games provide opportunities for students to experience disciplinary practices with visuals. However, prior research has…

This study examined the extent of perspective taking and language features represented in secondary students' text-based analytical writing. We investigated (1) whether perspective taking is related to writing quality, accounting for language features in writing; (2) whether students' English learner status is related to perspectives represented…

The present dissertation explores the effect of exposure to non-native speech via foreign film on non-native speech production and perception. In order to explore potential effects, two main experiments were developed, which examined French production and perception by monolingual native speakers of English before and after exposure to French…

The present study explored perceptual and articulatory techniques addressing the pronunciation of Spanish rhotics by means of a week-long computerized training. Through a quasi-experimental design approach, the study tested the utility of the online training and its effects on the phonetic production of taps [voiced alveolar tap or flap] and…

This study tells the story of first-grade teachers as they have experienced the return to the school building after year-long building closures. It identifies changes needed to support students' social-emotional needs having missed their kindergarten school year of face-to-face instruction in the school building. This study also explores teachers'…

This report looks at the provision of A level subjects in England in 2018. Provision in a subject is defined as the number or percentage of schools with at least one student taking the subject. It could be argued that this may not cover all of the 'provision' since schools might offer to provide a subject, but none of their students wants to study…

For a sustainable future, equipping sustainability change agents with relevant sustainability competencies is crucial. Among these competencies is system thinking competence -- the understanding of complex interrelationships among the dimensions of sustainable development and the impacts of the interrelationships. Learning approaches relevant to…

Via two reading experiments, this exploratory study examined the effects of over- and under-specified linguistic input on L2 online processing of Chinese referring expressions (REs). In each experiment, a group of advanced L2 Chinese speakers (all with Uyghurs as L1) and a control group of native Chinese speakers read 48 sets of 4 sentence pairs…

This research was designed to examine how teachers and students from various cultures (China vs. USA) might present distinct behavioural features in learner-centred classrooms. The findings of the research would serve the purpose to answer the question regarding whether and how learner-centred instruction could better support the learning of…

In the current study we used the gaze-contingent moving window paradigm to directly compare the second language (L2) English perceptual span of two groups that speak languages with essentially the same lexicon and grammar but crucially with different writing directions (and scripts): Hindi (read left to right) and Urdu (read right to left). This…

This study examines the quantity and quality of child-directed speech across household activities in a socioeconomically diverse sample of Argentinian Spanish-speaking children, an understudied population. Thirty children (mean: 14.3 months) and their families were audio-recorded for four hours. The middle two hours were transcribed and analysed…

This comparative case study examines the experiences of two Latinx teachers in the Southeastern United States who navigate critical social studies without substantive support in their schools. Their school spaces and experiences are myriad and overlapping, but generally the teachers describe being outside the traditional social studies curriculum,…
