Graph is a mathematic structure capable of representing a network of objects and their relationships. Clustering is an area in graph theory where objects are split into groups based on information of their connections. Depending on the field of the data, object clusters have various meanings, e.g., in the market basket analysis, clusters are families of products that are frequently or likely pu...

Although mathematical skills are an important component for business students, many students struggle to understand and meet the demands in different subjects. There is a considerable heterogeneity among subjects need good varies from subject subject. To analyse this, we apply Attitudes Towards Mathematics Inventory (ATMI) framework. The data collected by asking at school Norway. results linked...

Quasi-experimental research or quasi-experimental is an innovation from true experimenters, including difficult in the fields of education and social. Although this to do, many researchers are also interested using a design conducting research, especially field mathematics. The high interest study due fact that most suitable be applied mathematics which subject instructional by educators studen...

This paper presents the research project IFUN Interest and Interdisciplinary Instruction in Science and Mathematics. As researchers in mathematics and science education we are basically interested in how students’ learning and understanding in these subjects might be improved. Many research studies indicate that students’ interest in science and mathematics declines during lower secondary schoo...

One of the bottlenecks of current recognition (and graph matching) systems is their assumption of one-to-one feature (node) correspondence. This assumption breaks down in the generic object recognition task where, for example, a collection of features at one scale (in one image) may correspond to a single feature at a coarser scale (in the second image). Generic object recognition therefore req...

Semantic matching is a fundamental step in implementing data sharing applications. Most systems automating this task however limit themselves to finding simple (one-to-one) matching. In fact, complex (many-to-many) matching raises a far more difficult problem as the search space of concept combinations is often very large. This article presents Indigo, a system discovering complex matching in t...

In this paper, we address the problem of planning the textual organization of instructions. We take the view that natural language generation (NLG) is a mapping process of diierent levels of conceptual and textual representations. Within this framework , we consider the mapping between the text's semantic representation and its rhetorical structure. We argue that such a mapping is not direct, b...

The dynamic nature of linear and vector algebra, differential calculus or integration, could be in conjunction with a dynamic/interactive method of display. Although GeoGebra provides multiple representations of mathematical objects, it can help students discover connections between mathematical objects and their graphical representation. Students take more responsibility for their own learning...
