The Use of Triangulation Methods in Qualitative Educational Research
Triangulation involves the carejit! reviewing of data collected through different methods in order to achieve a more accurate and valid estimate of qualitative results for a particular construct. This paper describes how we used three qualitative methods of data collection to study attitudes of students toward graphing, hands-on activities, and cooperative grouping techniques using the triangul...
متن کاملLeveraging Event Data with Triangulation & Explicit Methods
Event logs are often voluminous and challenging to interpret. While event modeling offers a compelling addition to lab techniques, key aspects of user intent and satisfaction are often missing in event-based analyses. The unobtrusive nature of event logging is at the essence of its appeal to usability and research efforts. In this work, methods for augmenting event data to generate intent and s...
متن کاملAnisotropic Triangulation Methods in Adaptive Image Approximation
Anisotropic triangulations are utilized in recent methods for sparse representation and adaptive approximation of image data. This article first addresses selected computational aspects concerning image approximation on triangular meshes, before four recent image approximation algorithms, each relying on anisotropic triangulations, are discussed. The discussion includes generic triangulations o...
متن کاملUnderstanding Laser-based 3d Triangulation Methods
Machine vision systems based on 3D triangulation are employed in a range of industries from automotive and electronics manufacturing to lumber mills. While the basic concept of measurement using triangulation is simple, there are a number of important details that must be addressed when implementing such systems. These include how laser-based 3D triangulation systems are configured and how lase...
