How might teacher educators build a reflective and supportive community of practice with pre-service teachers? How might a visual (intermedia) journaling practice support critical and reflective thinking? How might an arts-based intermedia approach to analysis inform teacher educator pedagogical methods? These questions evolved and emerged…

This research study analyzes how the predictor variables sensing-intuitive learning style, verbal-visual learning style, gender, major, and degree level of adult learners predict student intrinsic motivation-to know, extrinsic motivation-external regulation, and amotivation to pursue an online graduate degree. The primary research question states:…

Skilled hearing readers activate phonological, orthographic, and semantic representations in order to recognize and comprehend words. However, deaf readers may achieve reading comprehension by different means. More specifically, enhanced visual attention, reduced access to phonology, and bimodal bilingualism may influence how deaf readers…
