The authors propose that these preliminary findings are consistent with a view of CAS as a disorder that not only affects motor planning but also has a phonological component.

Research methods courses are a critical component of teaching the applications of evidence based practice in the health professions. With the shift to online learning during the Covid-19 pandemic, new possibilities for teaching research methods have emerged. This case study compares two 5-week asynchronous online graduate level research methods courses in the field of Communication Sciences and Disorders. One online section of the course used traditional methods (TDL) common in face-to-face courses with recorded slide-based lectures, written discussion forums, and a final presentation. The other online section of the course used project-based learning (PBL), which consisted of weekly projects that forced students to engage with the literature and work both collaboratively and autonomously. We measured students’ research self-efficacy and course satisfaction before and after their courses. Overall, research self-efficacy was higher for the TDL class at both time points. However, the PBL class showed a higher percent increase in research self-efficacy, specifically for more difficult and unfamiliar tasks like statistical analysis. Students in both courses were equally satisfied with their course and instructor; however, students in the PBL class reported a greater workload and level of difficulty. We interpret the results as showing benefits of PBL in facilitating greater engagement with the research literature and course content; while TDL had advantages in students’ confidence with the course, likely due to familiarity with the instructional format.

There are differences and similarities between Modern Standard Arabic (MSA) and spoken varieties of Arabic, in all language domains. To obtain preliminary insights into interactions between the acquisition of spoken and standard varieties of a language in a diglossic situation, we employed forced-choice grammaticality judgments to investigate morphosyntactic knowledge of MSA and the local variant of Palestinian Colloquial Arabic (PCA), in 60 Arabic-speaking children aged 6 ; 4 to 12 ; 4, from a school in Nazareth. We used morphosyntactic structures which either differed or were similar between PCA and standard Arabic. Children generally performed better on items presented in PCA than in standard Arabic, with the exception of constructions involving negation. Children performed better on items when the two constructions were similar in both language varieties. We discuss the results with respect to the multiple factors that affect acquisition in a diglossic situation, and relate our findings to the possibility of interference effects of diglossia on learning.
