In this study, we investigated the relationship between student performance and learning styles for students enrolled in a basic business statistics course.  This course used a learner-centered approach that incorporated multiple teaching styles.  To assess our success in designing a course that facilitates learning for all learning styles, we evaluated the impact of students’ learning style on their performance in the course. 

To accomplish this analysis, we utilized quantile regression, a statistical technique from the economics literature developed by Koenker and Bassett (1978) that is an alternative to the classical ordinary least squares (OLS) regression.  Quantile regression allowed investigation of a more complete picture of student performance over the entire population as opposed to the mean effect from OLS regression.  

Learning style was not significant in determining a student’s overall course score for the entire cohort of students.  For small cohorts of students, learning styles were significant for exam average.  That is, some students experienced either a disadvantage or advantage due to their learning style for the exam course component.  However, for the overall course performance, a student with a particular learning style was neither advantaged nor disadvantaged.

This paper initially analyzes the determinants of net domestic migration which occurred from 1995 to 2000 at the county level in the 4-Corners Region of the U.S. (Arizona, Colorado, New Mexico and Utah.) Regression techniques were used to explain approximately 70 percent of the variation in net migration rates within the region for counties whose populations exceeded 10,000 persons at the beginning of the period. The results of the study suggest net migration flows in the region are a dual function of both economic and non-economic characteristics existing within each county. The analysis is extended through the use of additional multivariate techniques in order to group the counties into clusters that reflect natural groupings based on a similar profile of variables used in the analysis. Migration activity differed statistically from cluster to cluster based upon variations in the predictor variables used in the analysis. Further research is suggested in order to extend these results to the broader economy.

Plus-minus grading systems and other systems that increase the grading options beyond the whole-letter system of A, B, C, D, and F are now in wide use. However, a number of schools continue to use the traditional whole-letter system and changes in grading systems arouse strong emotions which can make implementation of a new system difficult or, in some cases impossible. This study first presents a review of the prevalence of alternative grading systems based upon examination of online catalogs. Then a survey of faculty and student opinions about implementation of a plus-minus grading system at a school currently using the whole-letter grading system is presented as well as a discussion of the motivation underlying these opinions. Because this study presents a thorough discussion of the comparative advantages and disadvantages of plus-minus grading systems to constituent groups, it should be of interest to faculty and policy makers at schools contemplating a change in their grading systems.

BACK TO THE FUTURE:
GENDER DIFFERENCES IN SELF-RATINGS OF TEAM PERFORMANCE CRITERIA?

Well functioning teams are essential to success in both academic and businesses environments today. While much research has contributed to our understanding of successful team characteristics, conflicting empirical evidence hinders corrective intervention. Information gathered from self- and peer-assessments is often used to provide feedback and encourage teams to take corrective actions. Unfortunately, these assessments have been shown to contain many biases. In this study, we isolate gender as an important contributor to assessment bias. By exploring the gender difference in under- and overrating self-assessment relative to peer assessment, we add support to the assumption that gender plays a role in assessment accuracy and contribute new understanding to the differences in gender response to feedback.
