This paper addresses learning analytics for evaluation of learners performance in remote laboratories. The objectives we identified to provide self-and social awareness while learners are practicing in their virtual learning environment are threefold: (1) the definition of a performance metric that requires no assessment tests, (2) the tracking of data to infer that metric in real time, and (3) the...
Existing approaches for egocentric activity recognition mainly rely on a single modality (e.g., detecting interacting objects) to infer the activity category. However, due to the inconsistency between camera angle and subject's visual field, important objects may be partially occluded or missing in the video frames. Moreover, where the objects are and how we interact with the objects are usually ignored...
Learning Analytic (LA) systems are aimed at supporting teachers in understanding the learning process by analyzing the information and the interaction of students with computer systems. In the case of a project-based learning process there is a need of introducing measure the student' activity as acquired via multiple modalities and then processed. The acquisition and processing needs to take into...
This paper explores how to exploit game based motivation as a way to promote engagement in computer-based instruction, and in particular in online learning interaction. The paper explores the human psychology of gaming and how this can be applied to learning, the computer mechanics of media presentation, affordances and possibilities, and the emerging interaction of playing games and how this itself...
Social networking sites have billions of users who communicate and share their personal information every day. Social engineering is considered one of the biggest threats to information security nowadays. Social engineering is an attacker technique to manipulate and deceive users in order to access or gain privileged information. Such attacks are continuously developed to deceive a high number of...
Skill rating is one of major issues in the world of sport, and even also in competitive games, which are being considered as a type of sport. However, to keep players engaged with the games, we have to match them against other player whose skill is close to theirs, the question is how can we rate skills of a player. We designed a novel method which is suitable for rating skill of players in Multiplayer...
This paper present a review of the school organizational culture. The research was carried out on a group of 30 teachers and the research methodology lay in applying a questionnaire regarding behavioral assessment within the organization.
European introduction of the eight key-competences and implicitly, the educational curriculum restructure at primary level by redefining educational outcomes and the introduction of the general and specific competences, led to the development in the Romanian educational system of the educational policy focused on skills training. The training based on competences has as premise the focus of the teaching...
The paper investigates the birth or one of the newest approaches in the curriculum design with big impact on current educational theories and practices. It is analyzed the effects of objectives centered pedagogy (OCP) on curriculum theory and practice as one of the dominant curricular approaches since 1950, when the curriculum was promoted as the paradigm of postmodern education. This rational model...
The use of computers and the Internet have changed classic methods of teaching and Learning, introducing the concept of distance Learning as a great opportunity for studying unfettered by constraints of time and space [1]. In addition, acquisition of new skills and knowledge is not only affected by an individual's mental schemes or beliefs, but also by their interaction, cooperation and collaboration...
The use of qualitative analysis to support software has been growing. The integration of these types of tools in research is accompanied by an increase in the number of software packages available. Depending on the design and research questions, researchers can explore various solutions available in the market. Thus, it is urgent to ensure that these tools, apart from containing the necessary functionality...
Hyperspectral image classification is a challenging problem as obtaining complete and representative training sets is costly, pixels can belong to unknown classes, and it is generally an ill-posed problem. The need to achieve high classification accuracy may surpass the need to classify the entire image. To account for this scenario, we use classification with rejection by providing the classifier...
Non functional requirements are very interesting specially in case of business relationships. In fact they are idioms of communication between business environment parties: provider and consumer. In particular in web services context, these requirements and non functional characteristics are also seen as a ranking and selection criteria. Thus, many researchers propose tools to measure the quality...
In the past two decades there has been a growing interest over the definition of new distributed computational paradigms capable to serve the need of manipulating and analyzing huge amounts of data. Among the others, the MapReduce outstands for popularity. Its open-source implementation Hadoop is widely used in academic environments and is also greatly supported by huge IT players. There are many...
Consumer choices are enormously influential in the success of the companies and organizations behind the highly competitive global service and product offerings of today. Consumer choice relates to preference, i.e. a set of assumptions a person creates around a service or a product such as convenience, utility or aesthetics. Furthermore, consumer preferences allow ranking of different assumptions...
Abstract-As people get excited about the latest idea for "Big Data" and the "Internet of Things", computer people often shake our heads and say "It won't scale." Pessimism isn't always justified: we have been able to scale up quite a number of tasks, from connectivity through search to social media. But other applications are recalcitrant, from energy management to medical...
Information Systems (IS) implementation in higher education is a large investment. Such investments are expected to bring increased efficiency and effectiveness, as well as better quality services to stakeholders. E-learning is one of the recent trends and major technological advancements in Information Technology (IT), reshaping the mode of delivery of education in universities. To effectively and...
A set of Context Sensitive Grammar (CSG) rules to translate Bangla imperative, optative and exclamatory sentences into English are introduced in this paper. In this paper, sentences are considered according to the function and purpose of the user rather than structure of the sentence. Three algorithms are implemented to complete major three steps of machine translation system (i.e., parsing, transfer...
Word Sense Disambiguation (WSD) is the task of automatically choosing the correct meaning of a word in a context. Due to the importance of this task, it is considered as one of the most important and challenging problems in the field of computational linguistics and plays a crucial role in various natural language processing (NLP) applications. In this paper, we present an improved version of a recent...
Several learning technologies have been developed over the years in order to help distance learning process. However, those technologies are still not enough to give the proper interaction between their users and the technologies themselves. It is caused by the absence of the technologies ability to give context based on their users conditions. When human interacts with each other, they understand...
