Boys and Girls in the Primary Classroom $70.07 This book illustrates how gender equity (and inequality) occurs in primary classrooms. It uses the findings of current research to provide teachers with recommendations for promoting equity amongst boys and girls. Each contributor summarizes recent research in the area of specialization before looking specifically at issues relevant to primary teaching and learning. The areas of the primary school covered include the National Curriculum subjects of literacy, numeracy and science, and broader topics such as working with boys, children with special educational needs, primary/secondary transition, playground cultures and childrens construction of gender identities. The book uses classroombased research to provide accessible accounts of investigations into gender and primary schooling. At the same time, it offers a critique of the whole drive towards evidence based research. Boys and Girls in the Primary Classroom is aimed particularly at primary teachers and student teachers although the research will be of interest to academics and undergraduate students.

The Boys and Girls Plutarch (Dodo Press) $31.06 Mestrius Plutarchus (c. 46 120), better known in English as Plutarch, was a Greek historian, biographer, essayist, and Middle Platonist. Plutarch was born to a prominent family in Greece. He studied mathematics and philosophy at the Academy of Athens under Ammonius from 66 to 67. He had a number of influential friends, including Soscius Senecio and Fundanus, both important senators, to whom some of his later writings were dedicated. His oeuvre consists of the Parallel Lives and the Moralia. He travelled widely in the Mediterranean world, including central Greece, Sparta, Corinth, Patrae, Sardes, Alexandria, and two trips to Rome. He led an active social and civic life while producing an incredible body of writing, much of which is still extant. His Life of Pyrrhus is a key text because it is the main historical account on Roman history for the period from 293 to 264 BC, for which neither Dionysius nor Livy have surviving texts. Amongst his other works are Plutarchs Lives (1914), The Boys and Girls Plutarch and Essays and Miscellanies. Author: Plutarch/ White, John S.
