Elementary school students’ and teachers’ perceptions toward creative mathematical writing with Generative AI
While mathematical creative writing can engage students in expressing mathematical ideas in an imaginative way, young learners struggle in this process. Generative AI (GenAI) offers possibilities for supporting them, such as providing story generation. As the design of GenAI-powered learning technologies requires careful consideration of the technology reception in classrooms, this study explores students’ and teachers’ perceptions of creative ma…
Students’ perceived roles, opportunities, and challenges of a generative AI-powered teachable agent: A case of middle school math class
Ongoing advancements in generative AI (GenAI) have boosted the potential of applying long-standing “learning-by-teaching” practices in the form of a teachable agent (TA). Despite the recognized roles and opportunities of TAs, less is known about how GenAI could create synergy or introduce challenges in TAs and how students perceived the application of GenAI in TAs. This study explored middle school students’ perceived roles, benefits, and challen…
Making the ‘mathematics register’ accessible to students: An exploratory study of two teachers’ discourse in an online lesson on polynomial expressions
The mathematics register, or the disciplinary discourse of mathematics, is demanding for many students because it is simultaneously technical, dense, multisemiotic, and multimodal. Teachers play a crucial role in making it accessible to students through oral explanations. Drawing on systemic functional linguistics, this exploratory study examined the discourse styles of two teachers – one experienced and one novice – who taught an identical onlin…

Generative AI in Art Education: A Systematic Review of Research Trends, Tool Applications, and Outcomes (2019–2025)
Generative artificial intelligence (GenAI) tools are transforming art education by enabling instant creation of textual, visual, audio, and multimodal outputs. This systematic review synthesizes research on GenAI applications in art education from January 2019 to August 2025. Following PRISMA 2020 guidelines, 19 peer-reviewed empirical studies across six databases (Web of Science, ScienceDirect, Springer, Taylor & Francis, Scopus, and ERIC) met i…
Development of a generative AI ‐powered teachable agent for middle school mathematics learning: A design‐based research study
This paper reports on a design‐based research (DBR) study that aims to devise an artificial intelligence (AI)‐powered teachable agent that supports secondary school students' learning‐by‐teaching practices of mathematics learning content. A long‐standing pedagogical practice of learning‐by‐teaching is powered by a recent advancement of generative AI technologies, yielding our teachable agent called ALTER‐Math . This study chronicles one usability…

Perceptual Salience of Tones, Vowels, and Consonants in Mandarin Speech Errors
The present study examines the perceptual salience of tonal speech errors compared with segmental errors (consonant and vowel). Tonal errors are observed less often than segmental errors. We thus hypothesize that tone errors are more easily ignored during transcription tasks because tones may have lower perceptual salience relative to segments. We test this hypothesis in Mandarin, via a number reconstruction task. Sixty-nine Mandarin native liste…
Development and validation of a patient-specific model to predict postoperative Sirs in older patients: A two-center study
Introduction: Postoperative systemic inflammatory response syndrome (SIRS) is common in surgical patients especially in older patients, and the geriatric population with SIRS is more susceptible to sepsis, MODS, and even death. We aimed to develop and validate a model for predicting postoperative SIRS in older patients. Methods: Patients aged ≥65 years who underwent general anesthesia in two centers of Third Affiliated Hospital of Sun Yat-sen Uni…

Lecklider's Love's Next Meeting: The Forgotten History of Homosexuality and the Left in American Culture, Oakland: University of California Press, 2021 Many historical accounts of the U.S. gay and lesbian liberation struggle date the beginning of radical sexual politics to the late 1960s, when activist groups such as the Gay Liberation Front linked the a…
Tree-based, two-stage risk factor analysis for postoperative sepsis based on Sepsis-3 criteria in elderly patients: A retrospective cohort study
Background: Sepsis remains the leading cause of postoperative death in elderly patients and is defined as organ dysfunction with proven or suspected infection according to Sepsis-3 criteria. To better avoid potential non-linear associations between the risk factors, we firstly used a tree-based analytic methods to explore the putative risk factors of geriatric sepsis based on the criteria in the study. Methods: Data of 7,302 surgical patients age…
Association of living arrangements with depressive symptoms among older adults in China: A cross-sectional study
Older adults living alone, or living with both a child and spouse were more likely to have depressive symptoms. It is important to provide more social services for those older adult, particularly for men living with a spouse and child
Impact of Oral Health Behaviors on Dental Caries in Children with Intellectual Disabilities in Guangzhou, China
Dental care is consistently reported as one of the primary medical needs of children with disabilities (IDC). The aim of the present study was to explore the influence of oral health behaviors on the caries experience in children with intellectual disabilities in Guangzhou, China. A cross-sectional study was carried out in 477 intellectually disabled children, 12 to 17 years old, who were randomly selected from special educational schools in Guan…
Counseling Role of Primary Care Physicians in Preventing Early Childhood Caries in Children with Congenital Heart Disease
The dental health of preschool children with congenital heart disease (CHD) is usually poor, which may contribute to the development of infective endocarditis (IE). Primary care physicians play an important role in providing access to preventive dental services, particularly for preschool children. The object of this study was to provide epidemiologic evidence for the impact of primary care physicians' (PCP's) counseling role on early childhood c…
