This article is a contribution to understanding of teacher actions that can contribute to a successful mathematics learning experience, defined as one that engages all students, especially those who may sometimes feel alienated from mathematics and schooling, in productive and successful mathematical thinking and learning. We offer an example of a task that can form the basis of such a learning...

متن کاملModeling Organic Chemistry and Planning Organic Synthesis
Organic Synthesis is a computationally challenging practical problem concerned with constructing a target molecule from a set of initially available molecules via chemical reactions. This paper demonstrates how organic synthesis can be formulated as a planning problem in Artificial Intelligence, and how it can be explored using the state-of-the-art domain independent planners. To this end, we d...

Practitioners who rely on adverse impact analysis for the evaluation and development of selection procedures need to carefully consider the adequacy of the samples used to compute adverse impact statistics. A method is presented for estimating the minimum sample size needed to test for adverse impact with adequate statistical power. The required sample size is often extremely large, particularl...
متن کاملOptimization in organic synthesis.
Organic Synthesis, quo vadis?3 has been a phrase, perhaps in a more modern language, on the lips of the practitioners of this demanding science-art, undoubtedly from the earliest times4 but more vigorously in the last two decades.5 Comparison of achievements of yesterday6 and today7 suggests progress in our abilities to construct molecules of complexity, with higher stereocontrol, faster analys...
