A survey was conducted to understand the service provisions for augmentative and alternative communication (AAC) in Hong Kong. The response rates of special pre-school training centers and special schools were 59% and 71%, respectively. The response rate of adult settings was 18%. Results indicated that a higher proportion of students identified as having complex communication needs had access to AAC service provision in schools for children with intellectual and physical disabilities than those in special pre-school training centres and other types of special schools. Generalization of AAC service beyond the classroom setting remains problematic. Seventy-two percent of the respondents were dissatisfied with the training in AAC that they received during their basic professional preparation. More advocacy work is needed to increase awareness and knowledge of AAC use in Hong Kong.
A growing body of literature has highlighted the pivotal role of peer feedback in teaching and learning. However, a paucity of studies explore the trend of literature in this research area, particularly using a bibliometric approach. Therefore, this study was conducted to reveal the major trends in the research area and construct an intellectual landscape of the relevant studies in the field. Bibliometric details of a total of 276 research articles, published from 1985 to 2020 (August), were retrieved from the Scopus database for further analysis. In particular, the publication trend, the most productive countries, the most productive authors, the top ten source titles, and keyword used in the research area, were explored using bibliometric indicators. The rapid growth of publications on peer feedback was observed since 2010, with a sharp peak noted in 2019. Furthermore, writing context was found as the central focus of peer feedback research. Among others, three key themes that surfaced out of term-occurrence analysis included: impacts/effects of using peer feedback approach, sub-themes concerning peer feedback implementation, and peer feedback in writing context. Additionally, from the review of 30 top-cited publications, 3 prominent themes: effects of using peer feedback approach, effective or ineffective peer feedback, and potential challenges or issues in peer feedback implementation emerged. Based on the findings, this paper concludes with some recommended avenues for future research.
Despite the growing research base on the use of video annotation in education, little is known on how to coherently structure a video-annotated peer feedback activity to engage students. Eventhough some studies have outlined the guidelines for conducting video-based annotation practice, little has been published with the focus on video-annotated peer feedback. To explore this under-investigated realm, the current review was conducted. In order to identify studies to be included in this review, a strategy for literature search was initially developed. This was followed by the selection and categorization of relevant studies. This paper thus provides a succinct overview of the essential steps involved in conducting a video-annotated peer feedback learning activity. Most importantly, it has resulted in a guide that outlines those essential stages and steps, thus providing insights into adaptation for use in education.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
