Is Over Practice Necessary? - Improving Learning Efficiency with the Cognitive Tutor through Educational Data Mining

This study examined the effectiveness of an educational data mining method – Learning Factors Analysis (LFA) – on improving the learning efficiency in the Cognitive Tutor curriculum. LFA uses a statistical model to predict how students perform in each practice of a knowledge component (KC), and identifies over-practiced or under-practiced KCs. By using the LFA findings on the Cognitive Tutor ge...

Improving Educational Quality (IEQ) Project

This paper combines the experiences of host country colleagues and U.S. education researchers to examine educational quality and the process of change. During the five years of the Improving Educational Quality (IEQ) 1 Project, education researchers worked collaboratively to examine issues related to quality in Ghana, Guatemala, Mali, South Africa, and Uganda. The principles which emerged from ...

Improving Bacteria Controller Efficiency

We present a novel approach that would enable the placement of dynamic sensor platforms in the most optimal areas for data collection in an environment of any size. Our approach would ensure that more sensors are placed in areas that contain interesting data and less in areas with little or no data. In this paper, we use a bacteria controller to nagivate the environment in the search of interes...

Efficiency of superabsorbents in improving water productivity

Agricultural residues and various other materials are currently being used as additives to improve the physical and chemical properties of soil. Iran is located in an arid and semiarid region, so using strategies to reduce water use will reduce the problem water scarcity. The use of superabsorbent to increase water uptake and retention is one of the solutions that have been applied to improve w...
