Modeling Student Benefit from Illustrations and Graphs

چکیده
We examine a corpus of physics tutorial dialogues between a computer tutor and students. Either graphs or illustrations were displayed during the dialogues. In this work, stepwise linear regression, augmented to remove unwanted terms, is used to build models that identify situations when each graphic may aid learning. Our experimental results show that grouping students by pretest score, then by gender produces a model that significantly outperforms the baseline.

Illustrations or Graphs: Some Students Benefit from One over the Other
We examine whether there are differences between students regarding the utility of learning from visual representations (illustrations or graphs) within the context of a typed natural language-based conceptual physics tutoring system. Showing half of the students only illustrations and the other half only graphs, we found that novices benefited from illustrations, whereas non-novices showed no ...
متن کاملModeling the Frequency Response Movements in Power Transformers for Predicting Purposes
Power transformers are key components in electrical power supplies and their failure could cause severe consequences on continuity of service and also generates substantial costs. Identifying problems at an early stage, before catastrophic failure occurs, is a great benefit for reliable operation of power transformers. Frequency Response Analysis (FRA) is a new, well-known and powerful diagnost...
متن کاملProblems in the integration of text and graphs
The aim of the present investigation was to establish the degree to which undergraduates use information in graphs inserted into written texts. Textbooks typically present graphs as do journals, newspapers, and magazines. Hence, university students repeatedly encounter graphs, both in and out of class, and the general assumption is that they will develop a solid knowledge base about how to inte...

متن کاملA Model for Runway Landing Flow and Capacity with Risk and Cost Benefit Factors
As the demand for the civil aviation has been growing for decades and the system becoming increasingly complex, the use of systems engineering and operations research tools have shown to be of further use in managing this system. In this study, we apply such tools in managing landing operations on runways (as the bottleneck and highly valuable resources of air transportation networks) to handle...
