Massive open online courses (MOOCs) show great potential to transform traditional education through the Internet. However, high attrition rates in MOOCs have often been cited as a scale-efficacy tradeoff. Traditional educational approaches are usually unable identify such large-scale number of at-risk students danger dropping out time support effective intervention design. While building dropout prediction models using learning analytics promising informing design for these students, results...
Ongoing advancements in generative AI (GenAI) have boosted the potential of applying long-standing "learning-by-teaching" practices form a teachable agent (TA). Despite recognized roles and opportunities TAs, less is known about how GenAI could create synergy or introduce challenges TAs students perceived application TAs. This study explored middle school students' roles, benefits, GenAI-powered an authentic mathematics classroom. Through classroom observation, focus-group interviews,...
Exosomes are nanosized extracellular vesicles (ranging from 30 to 120 nm) released many cells that provide promising biomarkers for the noninvasive diagnosis of cancer. However, traditional exosome-isolation methods tedious, nonstandardized, and require bulky instrumentation, thus limiting its clinical applications. In this paper, an anion-exchange (AE)-based isolation method was first proposed isolate exosomes directly plasma cell-culture medium with AE magnetic beads within min. isolated...
Multiple detection of pathogenic bacteria from urine samples was achieved on a centrifugal microfluidic chip using RPA.
Open-ended mathematical problems are a commonly used method for assessing students' abilities by teachers. In previous automated assessments, natural language processing focusing on textual answers has been the primary approach. However, questions often involve containing images, such as number lines, geometric shapes, and charts. Several existing computer-based learning systems allow students to upload their handwritten grading. Yet, there limited methods available scoring of these...
While mathematical creative writing can engage students in expressing ideas an imaginative way, young learners struggle 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 technology reception classrooms, study explores students' and teachers' perceptions with developed technology. We adopted a qualitative thematic analysis interviews 10 elementary...
The present cross-sectional study consisted of 18,265 Chinese patients not previously diagnosed with diabetes mellitus, and who underwent physical examination at the Third People's Hospital Shenzhen between June 2014 May 2015 (mean patient age, 51.312±15.252 years). was composed 11,770 males 6,495 females. aim to investigate association glycated hemoglobin A1c (HbA1c) levels, gender age. HbA1c values were measured using a Bio-Rad VARIANT™ II Reorder Pack. All data collected for analysis...
Discussion forums are increasingly central to massive open online courses (MOOCs), and it is vital for learners participate in associated forum activities. Active participation positively relates learner achievement that more posts yield better performance. However, this numerically aggregated measure overlooks the fact longitudinal trajectories of temporally vary among with different motivations taking MOOCs. To provide timely support stay engaged, important understand temporal variation...
Extracellular vesicles (EVs) are cell-derived nanoscale that provide promising biomarkers for the non-invasive diagnosis of cancer because they carry important cancer-related DNA, RNA and protein biomarkers. However, clinical application EVs is limited by tedious non-standardized isolation methods require bulky instrumentation. Here, we propose an easy-to-operate, simple dielectrophoretic (DEP) method EV with higher recovery efficiency (>83%) purity than ultracentrifugation (UC). The DEP...
Social and emotional learning (SEL) has been increasingly emphasized in educational research practice for promoting children's wellbeing. Perhaps the most well-known SEL framework is model provided by Collaborative Academic, Social, Emotional Learning (CASEL). This become dominant informing state standards, which guide educators' related practice. Yet, content of these standards not formally examined alignment with CASEL framework. The purpose this exploratory study was to evaluate...
