Achievement emotions with location-based mobile augmented reality: An examination of discourse processes in simulated guided walking tours     

Eric G. Poitras  Jason M. Harley  Yang S. Liu 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(6):3345-3360

The purpose of this study is to experimentally manipulate discourse processes hypothesized to impact the emotions students experience when interacting with handheld augmented reality devices in informal learning settings. Research conducted in the field is often limited by practical constraints, requiring heavy investments in time and resources to collect data from large samples of students. To demonstrate the feasibility of our proposed method, a guided walking tour with 60 students using a location-based augmented reality app was simulated in the context of a controlled laboratory setting. The difference between groups of students clustered into distinct profiles of positive and negative self-reported emotions was attributed to patterns in the mined dialog between students and tour guide. Furthermore, student engagement predicted the ability to recall topics covered in the tour. We discuss the implications and directions for future research in tour simulations conducted in a laboratory setting as a means to evaluate the role of mobile technologies in enhancing learning and desirable emotions.  相似文献   

Fostering the Development of Reading Skill through Supplemental Instruction: Results for Hispanic and Non-Hispanic Students     

Gunn B  Smolkowski K  Biglan A  Black C  Blair J 《The Journal of special education》2005,39(2):66-85

This paper reports the effects of a two-year supplemental reading program for kindergarten through third grade students that focused on the development of decoding skills and reading fluency. Two hundred ninety-nine students were identified for participation and were randomly assigned to the supplemental instruction or to a no-treatment control group. Participants' reading ability was assessed in the fall, before the first year of the intervention, and again in the spring of years 1, 2, 3, and 4. At the end of the two-year intervention, students who received the supplemental instruction performed significantly better than their matched controls on measures of entry level reading skills (i.e., letter-word identification and word attack), oral reading fluency, vocabulary, and comprehension. The benefits of the instruction were still clear two years after instruction had ended with students in the supplemental-instruction condition still showing significantly greater growth on the measure of oral reading fluency. Hispanic students benefited from the supplemental reading instruction in English as much as or more than non-Hispanic students. Results support the value of supplemental instruction focused on the development of word recognition skills for helping students at risk for reading failure.  相似文献   

Multiple description coding with spatial-temporal hybrid interpolation for video streaming in peer-to-peer networks     

YAO Jason  CHEN Homer H 《浙江大学学报(A卷英文版)》2006,7(5):894-899

INTRODUCTION Multimedia services over the Internet are be- coming popular due to the widespread deployment of broadband access. However, the conventional cli- ent-server architecture severely limits the number of simultaneous users, especially for bandwidth inten- sive applications such as video streaming. P2P net- works, on the other hand, offer a solution to the scalability problem. As a node joins a P2P network, it not only consumes resources but also contributes its bandwidth or comp…  相似文献   

Improving Malay Educational Achievement in Singapore: Problems and Policies     

Jason Tan 《Asia Pacific Journal of Education》1997,17(1):41-57

This article traces the development since 1959 of various policies aimed at upgrading Malay educational achievement in order to close the socio-economic gap between the Malay and non-Malay communities in Singapore. It analyses the various economic and political factors that have shaped policy decisions. Several recurrent themes in official discourse on the Malays' educational problems are highlighted, along with the tensions inherent in these policies. The article concludes by discussing the extension of the strategies initiated in the 1980s to encompass the economically disadvantaged sections of the Indian and Chinese communities as well.  相似文献

Can teachers and mathematicians communicate productively? The case of division with remainder     

Jason Cooper  Ronnie Karsenty 《Journal of Mathematics Teacher Education》2018,21(3):237-261

Is it possible that a meeting of mathematicians and primary school teachers will be productive? This question became intriguing when one professor of mathematics initiated a professional development course for practicing primary school teachers, which he taught alongside a group of mathematics Ph.D. students. This report scrutinizes the uncommon meeting of these two communities, who have very different perspectives on mathematics and its teaching. The instructors had no experience in primary school teaching, and their professed goal was to deepen the teachers’ understanding of the mathematics they teach, while teachers were expecting the course to be pedagogically relevant for their teaching. Surprisingly, despite this mismatch in expectations, the course was considered a success by teachers and instructors alike. In our study, we analyzed a lesson on division with remainder for teachers of grades 3–6, taught by the professor. The framework used for the data analysis was mathematical discourse for teaching, a discursive adaptation of the well-known mathematical knowledge for teaching framework. Our analysis focuses on the nature of the interactions between the parties and the learning opportunities they afforded. We show how different concerns, which might have hindered communication, in fact fueled discussions, leading to understandings of the topic and its teaching that were new to all the parties involved. The findings point to a feasible model for professional development where mathematicians may contribute to the education of practicing teachers, while they are gaining new insights themselves.  相似文献

Bottling fog? The quest for instructional management     

Joseph Murphy  Christine M. Neumerski  Ellen Goldring  Jason Grissom  Andy Porter 《Cambridge Journal of Education》2016,46(4):455-471

Elsewhere, the authors have unpacked instructional leadership and have documented that such leadership is associated with more effective schools. Indeed, there has been for a considerable time nearly universal acceptance that learning-centered leadership should provide the central platform on which leadership is enacted. In this paper, a less sanguine narrative is provided on instructional management. Specifically, it documents that for all the evidence and recognition of importance, learning-focused leadership remains a small domain of action for leaders at the school and district levels. It then focuses on both the culture of the profession of school administration and the nature of schooling to explain why in the face of considerable energy and effort only marginal improvements have been realized in deepening instructional leadership. It closes with an analysis of possible paths going forward.  相似文献

Who Talks to Whom in Malawi's Agricultural Research Information Network?     

Mariam A.T.J. Mapila  Jason Yauney  Paul Thangata  Klaus Droppelmann  John Mazunda 《The Journal of Agricultural Education and Extension》2016,22(1):7-23

Purpose: The sector-wide approach currently dominates as the strategy for developing the agricultural sector of many African countries. Although recognised that collaborative agricultural research is vital in ensuring success of sector-wide agricultural development strategies; there have been few efforts to understand the dynamics of national agricultural research/development networks in Africa. This study fills this gap by analysing the dynamics of networking and interactions between institutions in the National Agricultural Research System in Malawi. Design/Methodology/Approach: The study sampled actors in the National Agricultural Research System in Malawi, which included the main public agricultural research department, academic institutions, semi-autonomous research institutions, private companies and international agricultural research institutions. Data was analysed using Social Network Analysis. Findings: Results demonstrate that public agricultural research departments play a central coordinating role in facilitating information sharing; with other actors remaining on the periphery. However, it also shows the important role other actors play to relay information to a wider network of stakeholders. These secondary information pathways can play a very crucial role in ensuring successful implementation of the national agricultural research agenda. Practical implication: Policy-makers are called upon to integrate other research actors into the mainstream national agricultural research information network. This is vital as other research actors are, at the global level, increasingly taking up a greater role in financing and disseminating research and research results. Originality/Value: The study contributes greatly towards knowledge needed for continuing the transformation of African agricultural research; and aligning the African agricultural research vision and practice with the emerging global agricultural research paradigm.  相似文献
