New insights into an old problem – enhancing student learning outcomes in an introductory statistics course

Many students enrolled in first year introductory statistics courses believe learning statistics is a waste of time and fear they will fail. In this study, we explored the impacts on learning outcomes for students in an introductory statistics course by allowing students to arbitrarily choose their own sequence of learning from three key learning activities, namely tutorials, Peer-Assisted Study Sessions and Computer-Managed Learning quizzes. Unlike the old regime where the learning activities followed a strict, rigid sequence, a new regime allowed students to freely choose when, where and how they engaged with the course learning activities. This allowed increased opportunities for students to receive relevant and timely feedback. Using a total of 1187 students enrolled in semester 2 of 2011, 2012 and 2013, data were collected on students’ scores from 7 assessment tasks. Our experimental design ensured as many course features as possible remained constant between the control cohorts (of 2011 and 2012) and the experimental cohort (2013), thereby avoiding potential sample selection problems. The findings showed student learning outcomes in the new regime improved significantly. Interestingly, the effects were found to be greatest in the lower percentile of the score distribution.

Managerial Problem-Solving Styles: A Cross-Cultural Study

ABSTRACT

The literature suggests that North American business-people differ from their Latin American counterparts with respect to specific behavioral traits. Our particular interest is in problem solving and in effecting changes in behavior to achieve better problem-solving capability. The purpose of the present study is to assess whether there are differences in problem-solving styles between two culturally different groups of managers registered in MBA Programs: Anglo American and Latin American. Using Kolb's (1984 2006) Learning Style Inventory, it was found that Anglo American managers tended to be relatively action-oriented, “Convergers” (they emphasize decision-making and use deductive reasoning), while Latin American managers tended to be reflection-oriented, “Assimilators” (they emphasize planning and like to create models in their analyses) in their problem-solving styles. The positive and negative aspects of each style are discussed and suggestions for improved decision-making are offered.

RESUMEN. La literatura sugiere que los empresarios norteamericanos difieren de sus contrapartes latinoamericanos, en lo que atañe a ciertos trazos comportamentales específicos. Nuestro interés particular se orienta a la solución de problemas e implementación de cambios comportamentales, con el propósito de adquirir habilidades específicas para la solución de problemas. El propósito de este estudio es evaluar si existen diferencias entre los estilos empleados para solucionar problemas entre diferentes grupos culturales de gerentes matriculados en Programas MBA angloamericanos y latinoamericanos. Usando el sistema de estilos de Kolb (1984 2006) denominado Learning Style Inventory, descubrimos que los gerentes angloamericanos tienden a orientarse con bastante frecuencia en la acción, los llamados ‘Convergentes’ (que hacen hincapié en la toma de decisiones y el uso del razonamiento deductivo), mientras que los gerentes latinoamericanos tienden a volcarse a la reflexión, los llamados ‘Asimiladores’ (que hacen hincapié enplanear y les gusta crear modelos en sus análisis), como característica de sus estilos para solucionar problemas. Discutimos los aspectos positivo y negativo de cada estilo, y hacemos sugerencias para mejorar la toma de decisión.

RESUMO. A literatura sugere que os homens de negócios norte-americanos diferem de seus colegas latino-americanos em traços comportamentais específicos. Nosso interesse particular recai sobre a resolução de problemas e a introdução de mudanças de comportamento para obter uma melhor capacidade de resolução de problemas. O objetivo deste estudo é avaliar se existem diferenças nos estilos de resolução de problemas de dois grupos culturalmente diferentes de gerentes matriculados em cursos de MBA: anglo-americanos e latino-americanos. Utilizando o inventário LSI (learning style inventory) de Kolb (1984 2006), constatou-se que os gerentes anglo-americanos tendiam a ser relativamente orientados para a ação, “convergentes” (eles enfatizam a tomada de decisões e o raciocínio dedutivo), enquanto os gerentes latinoamericanos tendiam a ser orientados para a reflexão, “assimiladores” (eles enfatizam o planejamento e gostam de criar modelos em suas análises) em seus estilos de resolução de problemas. Os aspectos positivos e negativos de cada estilo são discutidos, e sugestões para melhorar a tomada de decisões são oferecidas.     

Nonparametric learning rules from bandit experiments: The eyes have it!

How do people learn? We assess, in a model-free manner, subjectsʼ belief dynamics in a two-armed bandit learning experiment. A novel feature of our approach is to supplement the choice and reward data with subjectsʼ eye movements during the experiment to pin down estimates of subjectsʼ beliefs. Estimates show that subjects are more reluctant to “update down” following unsuccessful choices, than “update up” following successful choices. The profits from following the estimated learning and decision rules are smaller (by about 25% of average earnings by subjects in this experiment) than what would be obtained from a fully-rational Bayesian learning model, but comparable to the profits from alternative non-Bayesian learning models, including reinforcement learning and a simple “win-stay” choice heuristic.     

Toward an Understanding of Strategic Inter-Organizational Relationships in Franchise Channels

Abstract

Information technology, globalization and the emergence of boundary-less communication networks are creating strategic networks of inter-organizational relationships. As inter-organizational relationships continue to evolve, there is a growing mandate for high levels of interdependency. Franchises are contractual vertical marketing systems and, by definition, represent highly interdependent linkages between franchisors, third-party providers, franchisees and customers. Organizational learning is posited as a strategic linkage in franchise systems.     

Economic corollaries of personalized recommendations

The impact of recommendation systems (RSs) on the diversity of consumption is not transparent or well understood. Available studies, whether experimental or theoretical, show inconsistent and even opposite results, which manifests as debate in the literature. In this paper, we investigate the impact of two main recommender systems, neural collaborative filtering and deep content filtering, on sales diversity via a randomized field experiment. Our results confirm the capability of recommender engines in increasing or decreasing aggregate sales diversity. Nonetheless, they amplify homogenization and reduce individual-level consumption diversity. In conclusion, our research reconciles seemingly contradict previous findings and illustrates that the design of the RS is the decisive factor in homogenizing or diversifying product sales.
