Pedagogic Conversational Agents are interactive educational systems that talk with students about a particular domain assuming the role of teacher, student or colleague. They have been used with good results from the upper areas of education to Primary Education. However, it has not been found examples in the literature of the field on its use in Early Childhood Education. During 2014/2015 several...
Shortage of qualified cybersecurity workforce is a national problem. Without an effective solution, people's daily lives, business operations, and even national security are in jeopardy. Higher education institutions have invested in various approaches to train college students to acquire cybersecurity related knowledge, skills, and abilities. The existing approaches still need improvement and refinement...
In order to better understand the emergence of online social networks, researchers usually employ state of the art synthetic topological models which can replicate some of the observed real-world social network characteristics. However, these characteristics rely on the analysis of common graph metrics at a certain point in time, when the snapshot of the real-world data is obtained. In other words,...
In this paper, we describe a demonstration of remote collaboration system using Empathy glasses. Using our system, a local worker can share a view of their environment with a remote helper, as well as their gaze, facial expressions, and physiological signals. The remote user can send back visual cues via a see-through head mounted display to help them perform better on a real world task. The system...
Teaching a course on game designing and development is as exciting as it is challenging. The "fun" factors have to be combined with art, narration, designing, and logic development. This paper strives to describe the pedagogy used for teaching this challenging course. Also discussed are some of the issues faced for the duration of the courses. Students' projects were implemented using Unity3d...
Computational thinking is central to recent approaches aimed at engaging K-12 students in computer science. Many strategies and metrics have been proposed to foster and measure such skills. The poster presents an empirical study which measures the understanding, recognition and rule construction ability of rising 3rd to 5th grade students from underrepresented communities. This poster also focuses...
The REU Site: Research Experience for Undergraduates in Collaborative Data Visualization Applications (VisREU) is a multi-year, interdisciplinary program that provides research experiences for undergraduates with an interest in visualization. The unique feature of the VisREU site is the paring of undergraduate students with research teams which consist of a research faculty member, graduate students...
Meta-analysis is a quantitative research method for synthesizing research results. This paper explores the application of meta-analysis in educational technology research from 2000. A total of 37 articles from 14 SSCI journals were selected and analyzed with the basic information of the articles, including the publication year and type of cooperation. Then, the moderator variables, such as grade level,...
While most health systems serve the majority of their citizens well, each has its challenges and gaps that lead to inadvertent marginalization of certain populations. The engagement of traditional stakeholders in health - policy makers, patients, health professionals, health administrators - to address these issues are necessary but insufficient if unconventional solutions are to be discovered. Use...
In this paper we evaluate the impact that a Computer Supported Collaborative Marking (CSCM) system has on the marking process of a highly subjective judging task. To do so, we evaluated the inter-rater reliability of reviewers in charge of marking written essays and the time required to perform such task. We analyzed the results of two groups of markers: the experimental group first marked 5 essays...
Instead of hybrid recommendation, recommendation system research mainly focused on improving the traditional algorithm. So, this paper proposes the hybrid recommendation model of commodity based on parallel computing. This model improves the results of the recommendation through combining various ways that have existed in the main e-commerce websites. In this model, there is one big problem that the...
In this paper, we conducted a review of techniques and methods used for collaborative data management for business purposes on the WEB. The aim was to propose a document flow optimization and to offer an information technology support for all departments of an organization. In a business organization or a firm, professionals involved in solving specific tasks either use the same data (common information)...
Some recent work proposed differential private collaborative filtering (DPCF) recommender systems to protect user privacy from indirect access attacks, e.g., KNN attacks. As the cost of such protection, the MAE of recommendation was retained with insignificant increase but the more focused metrics, i.e., the precision and recall of top-k recommendations, degraded unacceptable. To address this problem,...
Content-Centric Networking (CCN) proposals rethink the communication model around named data. In-network caching and multipath routing are regarded as two fundamental features to distinguish the CCN from the current host-centric IP network. In this paper, we tackle the problem of joint collaborative caching and multipath routing in CCN. We achieve this with an online and offline combination caching...
With the rapid development of online social network, people tend to express opinions and obtain information in social network. Due to the overwhelming amount of data in social network, users resort to recommendation system to find appropriate services or items. However, most current recommendation systems rely on the user to calculate the item evaluation results, which has many limitations in the...
Advent of the Social Web and the ever increasing popularity of Web 2.0 applications, has led to a massive amount of information. Therefore, users have difficulties in finding their desired information according to their interests and preferences. To address this issue, recommender systems have been emerged. These systems try to provide users with the most relevant and suitable information they need...
This paper describes a new heuristic approach letting an agent in a multi-agent system make a decision for selecting tasks to undertake. The proposed approach consists in giving the agent a profile including preferences and physical parameters, and a description of its beliefs about the environment. The decision engine allowing the agent to do a specific task is local to the agent and takes into account...
Real-time collaborative editing allows multiple users to edit a shared document at the same time. It received a lot of attention from both industry and academia and gained in popularity due to the wide availability of free services such as Google Docs. While these collaborative editing systems were initially used in scenarios involving only a small set of users such as for writing a research article,...
Plexlearning is one Cyberlearning response to Benjamin Bloom's long standing "Two Sigma Education Problem," since 1984. The problem is that Bloom's research confirms that an education system based on Mastery Learning and Expert one-on-one tutoring is significantly more effective than prevailing aggregate-based education delivery system. However, Bloom, this findings have been summarily dismissed...
A Body of Knowledge (BOK) is a term used to represent the complete set of concepts, terms, and activities that make up a professional domain. It encompasses the core teaching skills and research in a field or industry [13]. One of the main concerns of the software industry is to develop the talent of its human resources since the quality and innovation of its products and services depend of a great...
