Individuals with autism spectrum disorder (ASD) experience difficulties with daily life skills (DLS). Difficulties with DLS create obstacles to independence. To move into adulthood more smoothly, it is critical to teach some DLS during certain periods, such as adolescence. In the present study, the skills of preparing an instant soup, setting the…

Generalizing is a critical aspect of mathematics learning, with researchers and policy documents highlighting generalizing as a core mathematical practice. It can also be challenging to foster in class settings, and teachers need access to better resources to teach generalizing, including an understanding of effective forms of instruction. This…

Natural languages contain systematic relationships between verb meaning and verb argument structure. Artificial language learning studies typically remove those relationships and instead pair verb meanings randomly with structures. Adult participants in such studies can detect statistical regularities associated with words in these languages and…

In this study, we explored enacted task characteristics (ETCs) that supported students' quantitative reasoning (QR). We employed a design-based methodology; we conducted a teaching experiment with eight secondary school students. Through ongoing and retrospective analyses, we identified ETCs which supported students' quantitative reasoning. The…

The purpose of this study is to investigate how triadic dialog promotes generalization of growing figural patterns during classroom talk in multilingual classrooms and crucial linguistic terms that the teacher and students draw on in their home language, as they engage in pattern generalization. Ten sessions in two classrooms in grade 7 were…

Conjectures are a key component of mathematical inquiry, a process in which the students raise conjectures, refute or dismiss some of them, and formulate additional ones. Taking a design-based research approach, we formulated a design principle for personal feedback in supporting the iterative process of conjecturing. We empirically explored the…

A growing body of literature supports the effectiveness of Modified Schema-Based Instruction (MSBI) to improve mathematical problem-solving for students with autism spectrum disorder (ASD) and intellectual disability (ID). MSBI is an intervention package that teaches students to identify the problem structure and use a problem-solving heuristic to…

Young children who cannot use their natural speech to communicate their daily wants, needs, thoughts, and opinions often rely on augmentative and alternative communication (AAC) strategies that frequently use graphic symbols to assemble messages. Early intervention strategies typically focus on visual scene displays (VSDs) to place target messages…

A popular technology-based intervention is video-based instruction (VBI). VBI is known to be effective in teaching various skills to individuals with intellectual disability. Although many researchers have taught this population various skills using video modeling and/or prompting, none have conducted a literature review for this population. The…

Generalization is a critical component of mathematics learning, but it can be challenging to foster generalization in classroom settings. Teachers need access to better tools and resources to teach for generalization, including an understanding of what tasks and pedagogical moves are most effective. This study identifies the types of instruction,…

The purpose of this study was to evaluate the effects of using video-enhanced activity schedules on a laptop on the acquisition, maintenance, and generalization of schedule following, and pretend play skills in children with ASD. In addition, social validity data were collected from the teachers and the mothers of the participating children. Four…

A few case studies have suggested students' struggles with the "temporal order" of epsilon and delta in the formal limit definition. This study problematizes this hypothesis by exploring students' claims in different contexts and uncovering productive resources from students to make sense of the critical relationship between epsilon and…

This study used a video prompting intervention to overcome language barriers between English-speaking trainers and Spanish-speaking immigrant parents of children with autism. Parents were taught instructional skills targeting independent dressing. A multiple baseline design across three families and a replication using an alternating treatments…

For families and educators, understanding and working with children who experience a combination of deafness and autism spectrum disorder (ASD) can be challenging. Yet both understanding and work are crucial. For children with ASD to succeed, parents and educators need to understand them and to be able to work together to implement successful…

This study evaluated the effects of progressive time delay (PTD) to teach four elementary students with intellectual disability on how to self-instruct using a video activity schedule. A single-case multiple probe across participants design with a multiple probe across environments design for each participant was used to assess the generalization…
