One difficulty of teaching in mathematics is to present abstract mathematical concepts or laws to students in a simple visual way to promote students' understanding and mastery. Traditionally mathematical teachers tried to explain abstract mathematical concepts and formulas by means of some simple teaching tools and some mathematical models presented by some mathematical software, such as Matlab,...
An increase in student motivation is often cited as an expected effect of software visualization, but, as far as the authors are aware, no controlled experiments have yet demonstrated this. This paper therefore presents a controlled evaluation of this effect, conducted within the framework of self-determination theory. Students were tasked with removing redundant recursion in a multiple recursive...
The visual simulation system which the docking process of replenishment at sea is constructed based on MultiGen Creator and Vega Prime. In a bid to modeling and driving of the visual simulation, a large number of the real-time data should be transformed for simulation in which the entire process of replenishment at sea. According to the complicated power and movement state of the docking mechanism...
Along with the growth of the Internet of Things (IoT), the number of wireless devices and mobile nodes significantly increases and they are connected among them over wireless links. Many application software and network system software for these wireless devices/mobile nodes are being developing. However, we cannot confirm a wireless connection between the two adjacent devices, the network topology...
The unified program architecture of real time vision system (VS) with several fields of view construction is described. The offered architecture provides both onboard and stationary usage. In case of stationary usage, it provides determination of location and trajectory of objects movement in the ordered system of co-ordinates. Principles of open architecture, componential technology and use of standard...
Timeseries line charts are a popular visualization technique but traditionally do not show many lines. We borrow concepts of tiny microtext and path dependent cartographic text to embed labels and additional text directly into lines on line charts, thereby making it easier to identify individual lines in a congested line chart, enabling more lines to be displayed and enabling additional data to be...
The visualization of numeric data is becoming an important element in journalism, and new tools and platforms make the development of data visualization in the news discourse accelerate. In this paper we present an interview study investigating this development in Scandinavian newsrooms. Editorial leaders, data journalists, graphic designers, and developers in 10 major news organizations in Norway,...
MetricAttitude [18] is a visualization approach implemented in an environment that provides a mental picture of an object-oriented software by means of polymetric views of classes. In this paper, we describe a qualitative investigation we have conducted with a focus group involving developers aiming at evaluating their viewpoint on the relevance of the support MetricAttitude provides to perform comprehension...
Novice researchers have difficulties in operationalization (breaking down of abstract concepts to measurables) and generalization (generalize the findings to make claims). We have designed a system called OPeD (Operationalizing using ProblEm Decomposition), for teaching learning of operationalization. OPeD trains novice researchers in operationalization through problem decomposition. OPeD is based...
Open source software (OSS)-based product development takes advantage of feature updates and bug fixes from OSS communities. However, when we customize the OSS and do not return the changes back to the OSS communities, our customization and the updates sometimes conflict. That makes it difficult to apply forthcoming OSS updates since we need to grasp the software changes appropriately. We propose a...
Coordination in software projects is a challenge, particularly when it comes to distributed software development (DSD). Agile software development is a well-known paradigm for improving software development; however, there is little understanding of its impact on DSD projects. This paper describes an empirical study conducted within two Software Factory settings in Finland and Italy to investigate...
Metamodelling and model transformation play important roles in model-driven engineering as they can be used to define domain-specific modelling languages. During the modelling phase, modellers encode domain knowledge into models which may include both structural and behavioral aspects of a system. The contribution of this paper is a new web-based metamodelling and model transformation tool called...
Visuomotor integration (VMI), the use of visual information to guide motor planning, execution, and modification, is necessary for a wide range of functional tasks. To comprehensively, quantitatively assess VMI, we developed a paradigm integrating virtual environments, motion-capture, and mobile eye-tracking. Virtual environments enable tasks to be repeatable, naturalistic, and varied in complexity...
This research aims to associate the gap of old tradition teaching and learning mathematics with the help of dynamic mathematical software. Also, enhancing the learning capabilities and interest of students by creating a platform of variations to teach mathematics based on existing world problems. To improve the discovery learning procedure by empowering both the teacher and learner to visualize and...
This paper aims to demonstrate the potential of using the socio-constructivism approach and Information and Communication Technologies (ITC) to engage elementary school children in STEM learning. This study is based on a group of elementary school children, who have had the opportunity to learn scientific concepts through the use of prototypes, the construction of games including the themes in question...
The Web has become a necessary resource of daily use, the benefits it offers, being a source of knowledge, and collaboration giving rise to new initiatives such as linked data, whose purpose is link the data scattered through the Web through of semantic relationships between them. The propose of this article is show the improving, consumption, and visualization of linked data in the Web, in such a...
This work presents the planning, development and implementation of the SocioAVA digital educational material — Social Interactions in Virtual Learning Environments. This material is aimed at professionals working in Distance Education (DE) who are interested in discussing social interactions in the virtual. The objective is to discuss social interactions as an important factor to be included in pedagogical...
At present, internet and social networks are most used by teenagers. New on-line conduct and preferences have been generated by positive and negative content and easily accessed in the web without any parenting control. The purpose of this paper is to recall most common risks for teenagers like inappropriate content, pornography, websites with malicious software, contact avoidance with unknown people...
The propagation and dissemination of knowledge are extremely important elements for the collaboration of the country's scientific growth and development. One example is scientific collaboration networks, where interactions between two or more researchers occur, making it easier to share and perform tasks for a mutual purpose. The objective of this work is to analyze how the institutional scientific...
