This meta-analysis examined the ecological and population validity of intervention research for students with low mathematics achievement (SWLMA). Forty-four studies published between 2005 and 2019 that met the inclusionary criterion were included in this analysis. Our findings suggest, to improve the external validity and generalizability of…

Early child care and education providers provide instruction to diverse learners, including children with developmental delays but often lack training in use of evidence-based instructional strategies to support children's meaningful learning engagement. This preliminary study examined effects of the Early Achievements for Child Care Providers…

Mathematically gifted students have a high potential for understanding and thinking through mathematical relations and connections between mathematical concepts. Currently, it is thought that generalizing patterns algebraically can serve to provide challenges and opportunities that match their potential. This article focuses on a mathematically…

A multiple baseline with probe across participants design was used to investigate the effects of an oral narrative intervention on early developing personal narratives of four children aged 6 and 7 with autism spectrum disorder and severe language disorder. The individual intervention targeted the narrative macrostructure elements of…

This article investigates how children acquire word order generalizations from ambiguous and infrequent input. We focus on verb placement in Norwegian relative and complement clauses. In two elicitation experiments we explore where children (age 3-7) place verbs in three embedded clauses types: one requiring a purely syntactic generalization and…

Purpose: A meaning-oriented auditory training program for children who are deaf or hard of hearing (d/hh) was assessed with regard to its efficacy in promoting novel word learning. Method: While administering the auditory training program, one of the authors (Elizabeth Mauzé) observed that children were learning words they previously did not know.…

The present study investigates the effect of high variability phonetic training (HVPT) on the discrimination of second language (L2) vowel contrasts by adult speakers who live in a country where the L2 is dominant. The same subjects who participated in a previous discrimination task were trained in the discrimination of four L2 vowel contrasts…

Twenty-six participants aged 12-18 living in four countries were interviewed about their experiences participating in a digital exchange programme and learning about cultures. Abductive analysis of the transcripts suggests that social media-type learning formats offer particular opportunities for young people to: (1) engage with different cultures…

Statisticians have developed propensity score methods to improve generalizations from studies that do not employ random sampling. However, these methods rely on assumptions whose plausibility may be questionable. We introduce and discuss bounding, an approach that is based on alternative assumptions that may be more plausible. The bounding…

Mirror invariance or generalisation is the ability to recognise objects as being the same regardless of their spatial orientation. However, when, for example, learning to read Roman script, children need to hone these skills so that they can readily discriminate between mirror letters such as b/d or p/b. Korean Hangul makes a particularly…

Toddlers show high sensitivity to creator's intention when they interpret pictures. Previous research suggest that toddlers' performance can be facilitated in a picture comprehension task by making available the creator's intention that is, the social origin of picture-creation. The present study aims to test the generalizability of this…

One concern raised about teaching content from the general education curriculum to students with intellectual and developmental disabilities is whether they generalize the skills learned to typical performance settings. We conducted a literature review of research studies that taught content from the general education curriculum and assessed…

Novel causal systems pose a problem of variable choice: How can a reasoner decide which variable is causally relevant? Which variable in the system should a learner manipulate to try to produce a desired, yet unfamiliar, casual outcome? In much causal reasoning research, participants learn how a particular set of preselected variables produce a…

The purpose of this study was to evaluate the effects of intraverbal prompts on response diversity and novelty in intraverbals posed to children with autism spectrum disorder (ASD). The intraverbal prompts involving function, feature, and class (FFC) of an item were used in the training of three questions requiring multiple responses. Two Chinese…

The argument-based approach to validity (Kane, 2013) focuses on two steps: (1) making claims about the proposed interpretation and use of test scores as a coherent, interpretive argument; and (2) evaluating those claims based on theoretical and empirical evidence related to test performances and scores. This paper discusses the role of…
