Critics often characterise the study of educational technology as under-theorised. To test this assertion and to determine the extent of this criticism, the present paper reports an in-depth analysis of the 503 most recent empirical articles published in three selected education-technology-related journals (Computers & Education; Learning, Media and Technology; and British Journal of Educational Technology). These journals were selected because they publish studies related to all education settings rather than focusing on only a certain segment such as higher education; they have broad geographical catchment; and they were the most highly ranked journals in terms of their 2017 journal citation impact factor. The present paper examines how explicitly existing theory was identified in previous research, how theories were applied and how often these theories were advanced in education technology research. In the majority of cases, explicit engagement with theory was absent. Many studies either were wholly bereft of theories or made vague use of theory. Where theory was explicit, the articles were more likely to use theory to conceptualise the research, to inform the data collection or analysis process and to discuss the results. Very few articles reported findings that help us to learn something new about a particular theory (ie, little evidence of theory advancement).  相似文献   

Executive functioning and word reading in Hong Kong Chinese children: A 1-year longitudinal perspective     

Wing Kai Fung  Kevin Kien Hoa Chung  Chun Bun Lam 《Journal of Research in Reading》2020,43(3):382-393

This study examined the bidirectionality between kindergarten children's executive functioning (EF) and word reading across two time points. Participants were 523 Hong Kong Chinese-speaking children (mean age at Time 2 = 64.59 months; 52.9% male) and their parents. At Time 1, children were administered the measures of EF skills: inhibitory control, attention shifting, working memory and Chinese word reading. They were reassessed with these measures at Time 2 one year later. Results from the cross-lagged panel model revealed that, controlling for child age, gender and parental education levels, children's word reading at Time 1 was significantly predictive of their working memory at Time 2, but that the three EF skills at Time 1 were not predictive of word reading at Time 2. These findings underscored the role of early word reading in promoting children's working memory.  相似文献

The role of SES in Chinese (L1) and English (L2) word reading in Chinese‐speaking kindergarteners     

Duo Liu  Kevin K. H. Chung  Catherine McBride 《Journal of Research in Reading》2016,39(3):268-291

The present study investigated the relationships between socioeconomic status (SES) and word reading in both Chinese (L1) and English (L2), with children's cognitive/linguistic skills considered as mediators and/or moderators. One hundred ninety‐nine Chinese kindergarteners in Hong Kong with diverse SES backgrounds participated in this study. SES explained unique variance in English word reading even after age, phonological processing, vocabulary and working memory were controlled. However, the effect of SES on Chinese word reading became nonsignificant when these control variables were included. Moreover, phonological awareness showed a full mediating effect on the relationship between SES and Chinese word reading. Both phonological awareness and vocabulary were found to partially mediate the association between SES and English word reading. These findings complement our understanding of the relation between SES and reading development in Chinese societies and may have policy or intervention development implications.  相似文献

XMage: An image retrieval method based on partial similarity     

Chang-Ryong Kim  Chin-Wan Chung 《Information processing & management》2006

XMage is introduced in this paper as a method for partial similarity searching in image databases. Region-based image retrieval is a method of retrieving partially similar images. It has been proposed as a way to accurately process queries in an image database. In region-based image retrieval, region matching is indispensable for computing the partial similarity between two images because the query processing is based upon regions instead of the entire image. A naive method of region matching is a sequential comparison between regions, which causes severe overhead and deteriorates the performance of query processing. In this paper, a new image contents representation, called Condensed eXtended Histogram (CXHistogram), is presented in conjunction with a well-defined distance function CXSim() on the CX-Histogram. The CXSim() is a new image-to-image similarity measure to compute the partial similarity between two images. It achieves the effect of comparing regions of two images by simply comparing the two images. The CXSim() reduces query space by pruning irrelevant images, and it is used as a filtering function before sequential scanning. Extensive experiments were performed on real image data to evaluate XMage. It provides a significant pruning of irrelevant images with no false dismissals. As a consequence, it achieves up to 5.9-fold speed-up in search over the R*-tree search followed by sequential scanning.  相似文献

Developing an interactive augmented reality system as a complement to plant education and comparing its effectiveness with video learning     

Rong-Chi Chang  Liang-Yi Chung 《Interactive Learning Environments》2016,24(6):1245-1264

The learning of plants has garnered considerable attention in recent years, but students often lack the motivation to learn about the process of plant growth. Also, students are not able to apply what they have learned in class in the form of observation, since plant growth takes a long time. In this study, we use augmented reality (AR) technology to develop the ARFlora system, which can assist students in observing the changes in plant growth while in the classroom. More specifically, students are able to use AR markers to manipulate various virtual objects (e.g. sunlight) and observe the changes they have on plant growth. Meanwhile, a quasi-experimental evaluation is in place to substantiate the effectiveness of ARFlora in the learning of plants and to compare it with digital video learning. In the quasi-experimental design, 55 elementary-school students participated in the study. The participants are divided into two groups, an “experimental group” and a “control group.” The experimental group was taught using the ARFlora system, while the control group was taught by employing the digital video. Results show that (1) ARFlora and digital video have the same effectiveness on student's learning outcomes; (2) ARFlora is more effective in helping students retain learned knowledge; and (3) ARFlora is comparatively more useful in motivating students to learn about plants.  相似文献
