Methodological Challenges in the Analysis of MOOC Data for Exploring the Relationship between Discussion Forum Views and Learning Outcomes
PDF on ERIC Download full text
Bergner, Yoav; Kerr, Deirdre; Pritchard, David E. – International Educational Data Mining Society, 2015
Determining how learners use MOOCs effectively is critical to providing feedback to instructors, schools, and policy-makers on this highly scalable technology. However, drawing inferences about student learning outcomes in MOOCs has proven to be quite difficult due to large amounts of missing data (of various kinds) and to the diverse population…

Assessing Systematic Topic Difficulty Based on Query and Collection Features
Direct linkDirect link
Lu, Kun – ProQuest LLC, 2012
The performance of information retrieval systems varies significantly by test topics. Even for those systems that have performed well on average, the results for some difficult topics are still poor. Previous studies have revealed that different optimization techniques should be used for those difficult topics. However, a prerequisite of the…

Methods for Modeling Ordinal Outcome Variables.
Peer reviewed Peer reviewed
O'Connell, Ann Aileen – Measurement and Evaluation in Counseling and Development, 2000
Compares approaches to modeling ordinal outcome variables, including assumptions, interpretations, and limitations. Explores how the multiple regression approach with ordinal level data can compromise the understanding of the effects of the independent variables and of the ordinal level response. Provides applications with data from a multisite…

The Interaction between Temperament and Environment: Methodological Considerations.
Peer reviewed Peer reviewed
Plomin, Robert; Daniels, Denise – Merrill-Palmer Quarterly, 1984
Discusses the concept of temperament interactions in the context of statistical interaction. Categorizes temperament interactions that involve temperament as an independent variable, as a dependent variable, or as both. Describes use of hierarchical multiple regression for the analysis of temperament interactions. (Author/CI)

Examining the Credibility of Offsetting Contextual Effects. Report No. 250.
Karweit, Nancy L.; And Others – 1978
A strategy is proposed for dealing with educational research problems, using as an example a study based on data that had already been collected and using that data to discover how differences in school characteristics may result in differences in their students. The research method is based on concepts of analysis of covariance and is concerned…

The Relevance of the Identification Problem to Statistical Research on Capital Punishment.
Peer reviewed Peer reviewed
Yunker, James A. – Crime and Delinquency, 1982
Reviews several potential problems that often invalidate statistical tests of social theories. Discusses how there may be very serious identification problems in the estimation of the relationship between executions and homicides, and that serious questions may be raised regarding the validity of any particular estimation of this relationship.…
