This study is part of a broader on algebraic reasoning in elementary education. The research objective the present survey, namely to describe generalization among second grade (7- 8-year-old) students, was pursued through semi-structured interviews with six children connection contextualized task involving function y = x + 3. Particular attention paid structures recognized and type expressed by...

Three dual-task experiments were conducted to examine whether the underadditive interaction of the Simon effect and stimulus onset asynchrony (SOA) on Task 2 performance is due to decay. The experiments tested whether the reverse Simon effect obtained with an incompatible stimulus-response (S-R) mapping would show an overadditive interaction with SOA, as predicted by R.

While a software process is being exe cute d,many errors and problems occur which require to r econsider previously exe cute dprocess steps. In order to handle fe edback in a process management system, several requir ementsne ed to be addr essed: adaptability, human intervention, impact analysis, change prop agation, r estor ation of the work c ontext, and traceability.

We exhibit efficient algorithms to perform the following task: Given a function f defined on a finite subset E ⊂ R, compute a C function F on R, with a controlled C norm, that approximates f on the subset E.
