The present study evaluated a systematic instructional package including the system of least prompts (SLP) to teach differentiation and selection of tangible symbols to continue activities for two children with complex support needs and deafblindness (DB). A multiple probe design across three symbols was used to evaluate the intervention package…

Adult learners acquire second language (L2) allophones with experience. We examine two mechanisms which may support the acquisition of allophonic variants in second language acquisition. One of the mechanisms is based on the distribution of phones with respect to their phonological context (i.e. phonological distribution). The other is based on…

Online discussion boards are a standard learning management system (LMS) instructional tool used in the emerging online learning pedagogy. This pilot study examined an innovative approach that differs from how discussion boards have been commonly used. Using a retrospective, cross-sectional design, we evaluated the effect of shifting from…

Children's drawings of common object categories become dramatically more recognizable across childhood. What are the major factors that drive developmental changes in children's drawings? To what degree are children's drawings a product of their changing internal category representations versus limited by their visuomotor abilities or their…

This study is the extension of our previous visualizing study on the commognition processes in computer-supported one-to-one tutoring. With the help of the scale of commognitive responsibility score, we found that the main triggers of the commognition process shift are the positive transfer of knowledge and cognitive conflict. On the basis of…

Languages differ in the importance of acoustic dimensions for speech categorization. This poses a potential challenge for second language (L2) learners, and the extent to which adult L2 learners can acquire new perceptual strategies for speech categorization remains unclear. This study investigated the effects of extensive English L2 immersion on…

Music performance requires high levels of motor control. Professional musicians use body movements not only to accomplish and help technical efficiency, but to shape expressive interpretation. Here, we recorded motion and audio data of twenty participants performing four musical fragments varying in the degree of technical difficulty to analyze…

Substantial evidence exists suggesting that access to articulatory gestures during instruction improves students' phonological awareness skills, but researchers have yet to explore the role of articulatory gestures in initial phonics instruction. The purpose of this study was to examine if visual access to articulatory gestures (i.e., mouth cues)…

Geometry education is an important aspect of STEM education and career development, but it is often overlooked in K-12 education in the United States. Although there is some research on teaching geometry to students with learning difficulties at the elementary level, there is a lack of research on teaching advanced geometry skills at high school…

Research shows that the vast majority of students who are diagnosed with learning disabilities in school are, in fact, dyslexic. Still, many students with dyslexia are not adequately identified, assessed, or supported with research-based interventions. Adults with dyslexia report struggling with reading difficulties from as early as kindergarten…

This study sought to evaluate the impact of procedural facilitator training on the opinion writing paragraphs of elementary school- age students with autism spectrum disorder (ASD). Using a multiple probe, across participants' design, four children with ASD between the ages of 9 and 11 participated in procedural facilitator training through a…

Background: Processing and comprehending information from multiple sources have been a primary means of learning and are essential 21st-century skills to construct knowledge for a deeper understanding. Objectives This study examined students' individual differences in search strategies and internet epistemic beliefs as well as the effect of…

The present study was to explore whether dynamic visualizations enriched with visuospatial cues can optimize learners' cognitive processing of mechanical systems. The animated conditions and cueing patterns were the independent variables with an attempt to investigate their impacts on retention and transfer tests. Either dynamic or static…

Second language (L2) learners often have difficulty perceiving L2 sound contrasts when the first-language (L1) and L2 sounds are acoustically similar and these similar L2 sounds correspond to an existing L1 sound (Flege, 1995). To improve L2 learners' perception of sound contrasts, researchers have used high-variability phonetic training (HVPT)…

Researchers in mathematics education have focused on teacher beliefs as an important area of study because of their influence on teaching practices. In this study, we focused on two aspects of beliefs, the nature of mathematics and the teaching and learning of mathematics, with eight pre-service mathematics teachers (PMTs) to explore alignment…
