Improving e-learning involves various levels of supports. Accordingly, researchers usually adopt complex research designs with a multilevel structure or repeated measurements to capture a heuristic view of learners’ perceptions, comprehension, and behavior in e-learning settings. A total of 76 studies with Hierarchical Linear Modeling (HLM) as a multilevel modeling technique in 13 major e-learning journals from January 2000 to September 2022, published in the Web of Science, were reviewed. We assessed the applications of the following key criteria: reasons for using HLM, data characteristics, sample characteristics, model characteristics, variables used in the research, software use, and main technology used in the research. The results revealed that two-level models and random-intercept models are mostly used in multilevel model building. Moreover, most e-learning studies included two-level random intercept models with "students" as sampling units of analysis in Level 1, and "cognitive learning" (i.e., examination score, learning achievement) as the dependent variable in Level 1. Based on our review results, we provide suggestions and potential applications of using multilevel modeling in e-learning studies. © 2023 The Authors

The Effects of Humor Intervention on Teenagers’ Sense of Humor, Positive Emotions, and learning Ability: A Positive Psychological Perspective

引用

Journal of Happiness Studies 2023年第4期24卷 1463-1481页

作者： Liao, Yu-Hsiu Lee, Mei-Fang Sung, Yao-Ting Chen, Hsueh-Chih Department of Educational Psychology and Counseling National Taiwan Normal University Taipei Taiwan Institute for Research Excellence in Learning Sciences National Taiwan Normal University Taipei Taiwan Chinese Language and Technology Center National Taiwan Normal University Taipei Taiwan

Amid widespread concerns about the mental health of teenagers, this quasi-experimental study examines the effects of a classroom humor intervention on 268 seventh graders’ positive emotions, as well as their sense of humor and language ability. The participants completed self-report measures and a language exam before and after the intervention, which lasted six weeks. Analysis of covariance and mediation analysis were used to evaluate the effects. The results supported the researchers’ hypotheses that the humor intervention would significantly increase learners’ positive emotions, sense of humor, and language ability. The mediation analysis revealed that sense of humor mediated the relationship between the humor intervention and positive emotions, and that neither sense of humor nor positive emotion was the sole factor contributing to the observed learning gains. The study concludes that the intervention helped foster a learner-friendly environment in which the participants increased their positive emotions, sense of humor and language ability simultaneously, and makes recommendations for practitioners and future researchers on that basis.

Due to COVID-19, the primary teaching method has changed from traditional face-to-face teaching to online teaching. The present study explored the correlates between two personality traits, Neuroticism and Extraversion, and two types of self-efficacy, Internet self-efficacy and academic self-efficacy, on practical performance anxiety. Data from 273 technical college students were collected. Structural equation modeling analysis was performed. Results show that Neuroticism and Extraversion can predict students’ practical performance anxiety through Internet and academic self-efficacy. Moreover, Neuroticism can negatively predict Internet and academic self-efficacy. Extraversion can positively predict Internet and academic self-efficacy. The two types of self-efficacy can positively predict practical performance anxiety. According to the results, it seems necessary to reduce students’ practical performance anxiety by paying attention to their personality features and their self-efficacy.

ROCLING 2023 MultiNER-Health Task is to identify named entities in the healthcare domain. These recognized named entities need to be further classified into one of ten categories. This study proposes a threestage framework. The first stage of the framework is to recognize and categorize named entities using Label Semantics Model. This model employs both of textual content and label semantics to identify name entities and their categories. In the second stage, the Label Correction Model is used to correct abnormal labels. In the third stage, a rule-based approach is employed to revise the abnormal labels that cannot be corrected in the second stage. The proposed method is evaluated on three test sets provided by the task and its average F1score is 0.6838. It is the best performing model for SM test set among all participating task models. © 2023 ROCLING 2023 - Proceedings of the 35th Conference on Computational Linguistics and Speech Processing.

Most English foreign language (EFL) studies focus solely on human beings. This research explores how edge computing can facilitate learning for all things. The XoT (Xducation of Things) framework was proposed to educate both human and all things. All things encompass two terms: AI-Agent and smartthings (covering physical and digital smart objects). At the core of this framework is Smart Question Answer Forwarding Mechanism (SQA-Forwarding), specifically designed to assist all things in building knowledge. To demonstrate this, the smartXoT environment was developed based on XoT framework, and its impacts on EFL learners was assessed. A quasi-experimental study involving 26 EFL learners, divided into an experimental group (EG) and a control group (CG), examined the differences in learning achievement of smartthings and EFL learners when using the smartXoT environment with/without SQA-Forwarding. Findings, on one hand, indicated that smartthings in the EG developed knowledge bases greater than those in the CG. On the other hand, the interaction between EFL learners and smartthings with SQA-Forwarding significantly improved learners' writing skills, with revisions playing a crucial role in enhancing writing quality. Thus, the XoT framework offers a novel and promising approach to educating both humans and all things. © 2013 IEEE.

The human retina is a complex neural tissue that detects light and sends visual information to the ***, the molecular and cellular processes that underlie aging primate retina remain unclear. Here, we provide a comprehensive transcriptomic atlas based on 119 520 single cells of the foveal and peripheral retina of humans and macaques covering different ages. The molecular features of retinal cells differed between the two species, suggesting distinct regional and species specializations of the human and macaque retinae. In addition, human retinal aging occurred in a region-and cell-type-specific manner. Aging of human retina exhibited a foveal to peripheral gradient. MYO9A-rods and a horizontal cell subtype were greatly reduced in aging retina, indicating their vulnerability to aging. Moreover, we generated a dataset showing the cell-type-and region-specific gene expression associated with 55 types of human retinal disease, which provides a foundation to understanding of the molecular and cellular mechanisms underlying human retinal diseases. Such datasets are valuable to understanding of the molecular characteristics of primate retina, as well as molecular regulation of aging progression and related diseases.

ABSTRACTABSTRACTThe emergence of new media technologies has empowered individuals to not merely consume but also create, share and critique media contents. Such activities are dependent on new media literacy (NML) necessary for living and working in the participatory culture of the twenty-first century. Although a burgeoning body of research has focused on the conceptualization of NML, limited studies have explored English as a foreign language (EFL) learners’ new media literacy. Considering the importance of NML for EFL learning and teaching, this quantitative study aims to develop and validate a research instrument for assessing EFL learners’ new media literacy (ENML) in China. Confirmatory factor analysis was employed to further examine the relationships among the different indicators of ENML. The sample consisted of 974 EFL learners (669 males, 305 females) from a comprehensive university in China. A comparison of the five proposed models indicated that all of them were acceptable, including a first-order model and four second-order models. The first-order model includes 10 indicators: consuming skill, understanding, analysis, synthesis, evaluation, prosuming skill, distribution, production, participation, and feedback. The other four second-order models describe the relationships among the 10 indicators of ENML. These results along with their implications for further research are also elaborated.

Self-directed learning Predicts Online learning Engagement in Higher Education Mediated by Perceived Value of Knowing learning Goals

引用

The Asia-Pacific Education researcher 2022年第3期32卷 307-316页

作者： Sun, Wei Hong, Jon-Chao Dong, Yan Huang, Yue Fu, Qian School of Educational Technology Faculty of Education Beijing Normal University Beijing People’s Republic of China Department of Industrial Education Institute for Research Excellence in Learning Sciences National Taiwan Normal University Taipei Taiwan ROC School of E-learning Beijing University of Posts and Telecommunications Beijing People’s Republic of China

Online education has made it possible to implement the “classes suspended but learning continues” policy during the COVID-19 outbreak. However, the intangible sense of the online educational setting requires self-directed learning (SDL) and may force students to know the goals of learning that may impact their engagement. To understand the effect, based on situated expectancy-value theory, this study considered SDL as attitude and approach and constructed a research model to explore the mediating power of perceived value of knowing learning goals (PVKLG) related to participants’ online learning engagement during the COVID-19 lockdown. Data were collected from 497 higher education students in China. After the confirmatory factor analysis with structural equation modeling, the results reported that SDL attitude and approach positively predicted learning engagement mediated by PVKLG. The results suggest that only when students have a high level of PVKLG will they be able to regulate their learning process through the two types of SDL and enhance their engagement in online learning contexts during the COVID-19 lockdown.
