Validation of a learning hierarchy for the mole concept

Three psychometric methods for validating learning hierarchies are applied to one data set derived from responses of grade 10 chemistry students to items representing the skills in a hypothesized hierarchy for the mole concept. Two methods which considered skills in pairs, namely the “test of inclusion” by White and Clark and the “ordering-theoretic method” by Airaisian and Bart produced generally similar results. The third method, by Dayton and Mac-ready, considered the hierarchy as a whole and produced clearer distinctions between alternative hierarchies than the first two methods. The hierarchy derived from this analysis was supported by a test for transfer of learning from subordinate to superordinate skills.     

Reading,spelling and two types of irregularity in word recognition

How do good and poor readers, and good and poor spellers, vary in their decisions about words which have varying spelling-to-sound correspondences? This experiment isolates the effects of visual and phonological characteristics of words with schoolchildren of varying reading and spelling ability, aged between 9 and 11.5 years. Three groups of children were tested: good readers and good spellers, good readers who were poor spellers, and children who were both poor readers and poor spellers. The difference between‘good’and‘poor’was about two years according to the standardised tests which were used. The children performed a lexical decision task, deciding whether each letter-string was a word or not. Response times to three types of words were compared: standard regular words (e.g. SLOT, SPADE), words with common orthography but irregular spelling-to-sound relationships (e.g. HAVE, FEVER), and words with unusual orthography as well as irregular spelling-to-sound relationships (e.g. BISCUIT, ANSWER). The performance of good readers but not of poor readers was impaired on the words which were phonologically irregular (compared with regular words). Poor spellers were worse again on the dually irregular words, although not significantly, while the good spellers performed almost as well on these words as on the regular words. These results have a number of implications: that the regularity effect is phonologically and not orthographically mediated, that good readers use a predominantly phonological strategy in lexical decision while poor readers do not, and that for the best readers/spellers as tested here the orthographically and phonologically irregular words have some sort of special status which allows them to gain fast and accurate responses.     

Specialization and school organization: investigating pedagogic culture

Drawing on Bernstein’s notion of pedagogic culture or the ‘mode of being’ of the school, this paper develops and uses a theoretical framework for the analysis of school organization that draws attention to specialization of instructional practice. An understanding of the ordering principles of the school emerges from the analysis, fundamentally understood as relations of power and control in the school as an organization. The paper considers how the ordering principles of the school are related to differential performance. The framework is deployed in an analysis of six primary schools located in poor communities in South Africa.     

Exploring ICT Integration as a Tool to Engage Young People at a Flexible Learning Centre

The Edmund Rice Education Australia (EREA) Flexible Learning Centres aim to provide a supportive learning environment for young people who find themselves outside of the mainstream secondary schooling system. Drawing on twenty first Century learning principles, the Centres aim to deliver a personalised learning experience with an emphasis on flexibility and individual choice. Provision of a comprehensive curriculum enables young people to make positive future life choices and successfully transition into employment and further training. The aim of this research project has been to work with teaching staff at a Flexible Learning Centre in North Queensland, Australia, to explore the value of integrating ICT in the form of Web 2.0 technologies to enhance young people??s engagement with the subject of science. The findings of this case study suggest that ICT integration is effective in revitalising science education interest for disengaged young people. This may have wider implications in relation to general concerns of declining student interest and participation in science in the secondary years of schooling.     

Encouraging teacher development through embedding reflective practice in assessment

Learning to become a teacher is a developmental process, part of which is learning to become a reflective practitioner. The authors have implemented a structured approach to developing the habits of critical reflection, the purpose of which is to guide their university students (who are pre-service teachers) to progress through the stages of teacher development and to facilitate self-motivated professional growth. Their attempts to incorporate into these pre-service teachers' learning the ‘practice’ part of reflective practice have included the development of different kinds of practical and applied tasks. In turn, their attempts to incorporate the ‘reflective’ part of reflective practice have involved the embedding in assessment activities of different scaffolds for metacognitive reflection. Their innovative processes of embedding reflection in assessment have been guided by Dewey's and Schön's views of reflection, their own views of the teacher education process, and Brookfield's conception of ‘critical lenses’ which can be used as a scaffold to structure professional growth and development.
