The authors studied the perceived value of an interactive digital textbook LearnSmart (McGraw-Hill Education, New York, NY) and examined its implications on adaptive learning and student learning effectiveness. Constructionism and constructivism provided the theoretical foundation. Data were collected from an American public university over three semesters. Multiple regression analysis results show that LearnSmart improves students’ perceived competency and their satisfaction with LearnSmart, thus increasing their perceived value of using LearnSmart. In addition, perceived value of LearnSmart varies across different course delivery formats and devices, while perceived challenge has no influence on perceived value. Pedagogical implications and future research directions are discussed. 相似文献

We study the influence of social networks on labor market transitions. We develop the first model where social ties and job status coevolve through time. Our key assumption is that the probability of formation of a new tie is greater between two employed individuals than between an employed and an unemployed individual. We show that this assumption generally generates negative duration dependence of exit rates from unemployment. Our model has a number of novel testable implications. For instance, we show that a higher connectivity among unemployed individuals reduces duration dependence and that exit rates depend positively on the duration of the last job held by the unemployed worker. 相似文献

This article proposes a fully integrated and interactive elicitation-optimization procedure for portfolio management. A soft computing approach based on fuzzy logic is developed as an alternative to the traditional mean variance model and compromise programming approach. The models are applied to farmers to examine whether they should buy publicly traded food and agribusiness firms stocks rather than invest in a broader market stock portfolio. Results suggest that investments in publicly traded food and agribusiness stocks allow farmers to capture additional benefits beyond those of simply diversifying in the broader market. 相似文献
