A Triangulated Approach to the Modelling of Learning Outcomes in First Year Economics

Initial insights derived from modelling aspects of learning outcomes in the first year study of economics are presented. Of particular interest are three forms of entering students' prior knowledge: (a) subject-specific prior knowledge; (b) conceptions of learning, and (c) learning history. Part 1 compares the analyses of variance of inventory responses of the 1998 first year cohorts of the Universities of Adelaide and South Australia. Results across the two universities are consistent in confirming the significant effects of having studied economics at school, having English as a second language, and holding economic misconceptions, on (end of semester one) learning outcomes. Part 2 models learning outcomes using three approaches: (a) a single dimension of variation (selected from a more complex common factor model) which is then used to inform; (b) a k-means cluster analysis; and (c) a non-linear regression analysis. This "triangulation" of approaches produces different but complementary insights into the underlying relationships being modelled and improves our understanding of the learning engagement processes of entering first year economics students.     

To maintain circularity: Biological roots of education

Truisms have the disadvantage that by dulling the senses they obscure the truth. Almost nobody will become alarmed when told that in times of continuity the future equals the past. Only a few will become aware that from this follows that in times of socio-cultural change the future will not be like the past... At any moment we are free to act toward the future we desire. In other words, the future will be as we wish and perceive it to be. This may come as a shock only to those who let their thinking be governed by the principle that demands that only the rules observed in the past shall apply to the future. For those the concept of change is inconceivable, for change is the process that obliterates the rules of the past (Von Foerster, 1972).     

ANCHORING ADHD SYMPTOMS TO MENTAL AGE

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM‐5), requires that symptoms of ADHD must be developmentally inappropriate in order for an ADHD diagnosis to be considered. Because the DSM‐5 does not specifically outline procedure for determining developmental inappropriateness of behaviors, practitioners do not have guidance for making this consideration. To explore the relationship between mental age and behavior ratings of ADHD symptoms, the cognitive and behavioral data from 50 children who were evaluated in a school or clinic were compiled for this study. Cognitive ability scores were used to calculate mental age and behavior rating scores were then recalculated using the assessed mental age. Using the recalculated behavior ratings, scores based on mental age decreased significantly on the Attention Problems, Hyperactivity, and Atypicality scales of the BASC‐2. Additionally, as the discrepancy between mental and chronological age increased, larger differences in scores were found.     

Informing parents about educational options. How well are we doing?

This study explores an aspect of information delivery to parents by focusing on those who have chosen residential school placements for their children. Although most parents choose to send their deaf children to special programs in regular public schools, some do opt for residential school placements. Little is known about the foundations on which such decisions are made, and this study is a preliminary attempt to better understand parents' motives and expectations and to assess the adequacy of information provided to them. In 128 surveys from a sample of parents nationwide, a surprising number reported that they were not given information about placement options. Of those who were, many said they were dissatisfied with the information. A large proportion of the parents were satisfied with the residential school. The relationships among their reasons for this placement, their views of the advantages and disadvantages, and the information provided to them are discussed.     

Notes on Classroom Practice and the Ownership and Use of Personal Computers Amongst Egyptian Science and Mathematics Teachers

This paper reports a study of the acquisition and use of personal computers by Egyptian science and mathematics teachers. Self-report data was collected from the same teachers on how they had changed their classroom activities and professional practice since their return to Egypt following a twelve-week in-service course in the United Kingdom. The data from this sample of teachers is compared with that from a second sample, who also attended the same in-service programme, but did not report the purchase of a personal computer. Analysis indicates that the Egyptian teachers with personal computers have tended to concentrate on improving the quality of current practice, through better preparation and student testing, rather than introducing major, paradigmatic, changes to their teaching.
