    An ethnographic investigation into the development and trialing of more accessible text materials for second language teaching and learning in physical science
    (1993) Clark, Jonathan; Clark, Jonathan; Pickerill, Roy Thomas Alan; Young, Douglas
    This dissertation discusses the development of alternative science curriculum materials for a secondary schooling context where English, the medium of instruction, is a second language for both teachers and students. The research is located in an interpretative ethnographic framework and the data gathered during the classroom-based trialing of the materials highlights the vital role of language in the teaching and learning of school science. An interactive reading model coupled with a discourse approach to text analysis explores some of the language difficulties which black students experience with their science textbooks. That many students fail to develop adequate reading strategies is identified as lying at the heart of many learning problems. It is suggested that the key to comprehension is instruction from a base of more accessible text materials. Furthermore, although science practical work does not automatically advance students' knowledge and understanding, relevant and contextualised learning activities do equip students to become more self-directed and reflective learners of science.

    A critical evaluation of recent research into semantic development in child language
    (1988) Pickerill, Roy Thomas Alan; Love, Nigel
    This study examines critically recent research in the area of child language development, with an emphasis on research into semantic development. Various research articles, in particular, are analysed, with particular attention being given to experimental studies. In addition, research into language development in the naturalistic mode is discussed. The validity of research into language development in experimental contexts is questioned. Specific methods employed in experimental studies of language development are discussed critically. These methods are contrasted with methods used in a number of naturalistic studies. Recent research into semantic development is placed in the perspective of the study of semantics as a whole. The principal finding of this study is that research into language development in artificial experimental settings does not allow for valid conclusions to be drawn. Naturalistic studies are preferred in that they allow for language development, and semantic development in particular, to be placed in the context of overall child development. Language development is not able to be abstracted, for research purposes, from the totality of human development. Semantic development is viewed as a continuous process, lasting well into adulthood. The importance of the study of semantic development as part of semantics is emphasised.
