Hints: You Can't Have Just One
A student using an interactive learning environment (ILE) may take multiple attempts to solve a problem step, at times using hints. But how effective are hints?

We demonstrate this by re-investigating semantic CM under the perspective of the recent development of syntactic CM. Besides clarifying and high-lightening the analogies and essential diierences between the syntactic an...
متن کاملForbidding Just One Intersection
Following a conjecture of P. Erdos, we show that if 9 is a family of k-subsets of an n-set no two of which intersect in exactly I elements then for k 2 21+ 2 and n sufficiently large IF:/ < (;:‘,I:) with equality holding if and only if 9 consists of all the k-sets containing a fixed (I+ I)-set. In general we show 19) <dknmax(‘.k-‘-l), where dk is a constant depending only on k. These results ar...

The term brain activity refers to a wide range of mental faculties that can be assessed either on anatomical/functional micro-, mesoand macrospatiotemporal scales of observation, or on intertwined levels with mutual interactions. Here we show, based on novel topological findings, how every brain activity encompassed in a given anatomical or functional level necessarily displays a counterpart in...
