Discovering ethnic root behavior patterns: Towards an applied Canadian ethnic studies

This paper reports a method used with six groups of either students or community professionals, since 1977, to experiment with inductive ways of identifying “ethnic root” behavior patterns. Such patterns are hypothesized to develop beyond the immigrant generation as ethno-culturat patterns and are passed on in the context of socialization. An acculturative framework is proposed to denote benchmarks in the cultural accomodation of individuals and families, through several generations. Along with this framework, the evolution of an ethnic behavior pattern is graphically depicted.A method is developed to identify the pattern beyond the level of conscious remembrance; (it is assumed that adult immigrants will remember the patterns from the country of origin). Although the method is interesting as an avenue of investigation in its own right, it was developed primarily as a conceptual tool to assist community professionals to understand ethnic-related material in their daily work. Three uses of the framework are outlined. First, it draws attention, in the counselling situation, to the level of integration into Canadian society that the client displays. Second, by getting in touch with the personal ethnic pattern that they own, the practitioner him/herself begins to understand the nature of ethno-culture, and thereby appreciate the presence of it in others. Third, the method permits the practitioner to identify personal values of an ethno-cultural sort that can interfere with practice.

Phonemic segmentation and blending skills of kindergarten children: Implications for beginning reading acquisition

This study explored the abilities of kindergarten children in segmenting and blending phonemic components of words and the relationship of these abilities to beginning reading acquisition measured by the word recognition subtest of the Wide Range Achievement Test (WRAT) and to auditory discrimination defined by performance on the Wepman Test of Auditory Discrimination. Random assignment of 103 kindergarten children to six experimental groups was used to evaluate phonemic segmentation and blending skills and to one control group to assess the relationship of these skills to auditory discrimination. Each experimental group received training in one of three types of word division (either C-V-C, CV-C or C-VC) for phonemic segmentation and blending in one of two task sequences (either blending first or segmentation first). Results indicate that segmentation is significantly more difficult than blending and that C-V-C is the most difficult of the three types of word division for both segmentation and blending. There were no significant differential effects of the training and control procedures on a pretest and posttest of the Wepman. Follow-up with the WRAT 1 year later indicated that C-V-C segmentation is a highly useful predictor of beginning reading acquisition. Implications for teaching of reading and for the interpretation of Wepman results are included.
