Dear MLE friends, UNESCO put an other good and helpful MLE related publication on the Web: " Mother tongue matters: local language as a key to effective learning " is now available on-line. This book contains case studies from Papua New Guinea , Mali and Peru . It also contains a section on the Thomas and Collier longitudinal study. If you rather look for recommendations read the "Key Findings" chapter. I copy the conclusion chapter below. http://unesdoc.unesco.org/ulis/cgi-bin/ulis.pl?catno=161121&set=49AC0AB5_1_167&gp=1&mode=e&lin=1 The book is written by Dörthe Bühmann and Barbara Trudell.
