Learning in Design and Technology: The Impact of Social and Cultural Influences on Modelling

The paper introduces the highly problematic nature of modelling in design and technology education and examines the relationship between cognitive and concrete modelling. Its aim is to gain insight into what learners do, rather than what others say they ought to do in their learning activities. The variety of purposes that educators have for learners’ modelling are discussed through examining the contested curriculum justification for design and technology education itself. The paper proposes that learners’ modelling cannot be extracted from the social milieu in which they act and it provides some insights of these social influences through the analysis of two case studies. Their settings are a girls’ secondary school and a college of higher education. Each case study is presented independently but organised with a common format to consider a) the impact of assessment on learning intentions and outcomes; b) cultural influences on learning and modelling; c) social influences on learning and modelling. A discussion of the emergent themes considers implications for teachers. This revised version was published online in July 2006 with corrections to the Cover Date.     

Comparing the True Cost of Living Indices of Demographically Different Households

The comparison of true cost of living indices between demographically different households (relative equivalence scale) is argued to be sensitive to the way demographic characteristics enter demand analysis. In particular, parameters reflecting the cost of demographic characteristics at base prices, though themselves do not have welfare (equivalence scale) interpretation, can alter the benchmark from which demographically varying inflation effects are measured. The empirical analysis, based on a rank‐3 demand system applied to UK individual household data, shows that the inflation adjustment of child benefits can vary with the way demographic costs at base period prices are specified.

Can Business Ethics be Trained? A Study of the Ethical Decision-making Process in Business Students

The purpose of this paper is to examine the various guidelines presented in the literature for instituting an ethics curriculum and to empirically study their effectiveness. Three questions are addressed concerning the trainability of ethics material and the proper integration and implementation of an ethics curriculum. An empirical study then tested the effect of ethics training on moral awareness and reasoning. The sample consisted of two business classes, one exposed to additional ethics curriculum (experimental), and one not exposed (control). For the experimental group, ethics exercises and discussion relevant to each topic were completed. Findings suggested gender differences such that, relative to other groups, women in the experimental group showed significantly improved moral awareness and decision-making processes. An explanation of the underlying cognitive processes is presented to explain the gender effect.
