An increasing number of studies have investigated the effects of different types of corrective feedback. However, doubts have been raised whether field (in)dependent (FI/FD) L2 learners benefit differently from the explicit type of corrective feedback (i.e., metalinguistic). This study examined the (possible) effects of metalinguistic feedback on FI/FD intermediate L2 learners’ writing accuracy...

In the paper (Theoret. Comput. Sci. 237 (2000)) Anderson present a theorem which characterizes any semiretract S by means of two retracts R and R!: The /rst part of the paper contains a counterexample for this characterization. Then some results are presented which /nally lead to the theorem which determines for a given semiretract S the minimal number of retracts R1; : : : ; Rm such that the e...
