Toward a Deeper Understanding and Prediction of Achievement, Success,
and Affect of Students in Virtual High School Courses:
A Quantitative Analysis of Variation of Student Measures within Course by Type of Course

Notes for the MVHS Advisory Council Meeting
April 20, 2005
W. Patrick Dickson

Introduction. This project is focusing on the intensive analysis of the within class variation of individual achievement, attrition, and affective responses to online learning in a systematic sampling of the several types of courses offered by the Michigan Virtual High School. In addition to these analyses, building on ideas derived from Tufte's work on the visual display of quantitative data, we are attempting to go beyond the usual data analyses to explore ways of representing data in ways explicitly crafted to inform policy makers, teachers, students, and other stakeholders.
