Words refer to objects in the world, but this correspondence is not one-to-one: Each word has a range of referents that share features on some dimensions but differ on others. This property of language is called underspecification. Parts of the lexicon have characteristic patterns of underspecification; for example, artifact nouns tend to specify…

Purpose: The ultimate goal of aphasia therapy should be to achieve gains in function that generalize to untrained exemplars and daily conversation. Anomia is one of the most disabling features of aphasia. The predominantly lexical/semantic approaches used to treat anomia have low potential for generalization due to the orthogonality of semantic…

Much evidence suggests that, from a young age, humans are able to generalize information learned about a subset of a category to the category itself. Here, we propose that--beyond simply being able to perform such generalizations--people are "biased" to generalize to categories, such that they routinely make spontaneous, implicit…

In contrast to the large body of research investigating intervention for poor decoding skills, far fewer studies have evaluated interventions for reading comprehension. There is even less research on children with more specific difficulties with reading comprehension, often referred to as "poor comprehenders". Levels of effectiveness…

Special educators are urged to use research findings to inform their instruction in order to improve student outcomes. However, it can be difficult to tell whether and how research findings apply to one's own students. In this article, we discuss how special educators can consider the samples and the sampling methods in studies to examine the…

In this commentary, Mary James highlights two problems she deemed critical during her work exploring the relationships between assessment and learning in theory and practice. First, efforts to improve assessment for learning were not always successful either in improving performance or in other ways. Second, and this may be a reason for the first…

A proof is a connected sequence of assertions that includes a set of accepted statements, forms of reasoning and modes of representing arguments. Assuming reasoning to be central to proving and aiming to develop knowledge about how teacher actions may promote students' mathematical reasoning, we conduct design research where whole-class…

Purpose: The benefit of stimulus variability for generalization of acquired skills and knowledge has been shown in motor, perceptual, and language learning but has rarely been studied in reading. We studied the effect of variable training in a novel language on reading trained and untrained words. Method: Sixty typical adults received 2 sessions…

With the rising number of individuals diagnosed with autism and other developmental disabilities comes an increased need for effective assessment and treatment options. Previous research has indicated that applied behavior analytic techniques are among the most empirically supported and utilized treatments for this population; however, curriculum…

Evidence-based practice (EBP) is the norm and expectation for providing interventions in school psychology. However, there are two major hurdles to be addressed before EBP can be a true improvement in providing educational and psychological interventions to children and families. The first challenge is that the standard of clinical research limits…

Generalization has been a major focus of curriculum standards and research efforts in mathematics education. While researchers have documented many productive contexts for generalizing and the generalizations students make, less attention has been given to the processes of generalizing. Moreover, there has been less work done with high school…

The study reported in this article addresses the question of how professional development can increase teacher noticing of student thinking over time. The data come from five teachers' participation in a two-year professional development intervention that combined lesson study, video clubs, and animation discussions. The analysis focuses on…

Simulation-based learning offers a wide range of opportunities to practice complex skills in higher education and to implement different types of scaffolding to facilitate effective learning. This meta-analysis includes 145 empirical studies and investigates the effectiveness of different scaffolding types and technology in simulation-based…

Aim: This research aimed to explore the impact of school-based Lego Therapy groups for adolescents with a diagnosis of ASD [autism spectrum disorder] in mainstream schools. Method/Rationale: School staff were trained in the delivery of the social skills intervention to groups comprising one adolescent with ASD and two typically developing peers. A…

In today's climate, with the ever-increasing demand for competent behavior analytic services, it is necessary for behavior analysts to work across a variety of settings, including home, school, and community, overseeing instructional aide staff as the frontline providers of applied behavior analysis (ABA) services. It is common practice for ABA…
