Derek Jarman: An Art Educator for Our Times?

Derek Jarman found his life's purpose in art. His significance for art educators today is his combination of low technology film‐making and his painterly vision. He provides a model for us today, in his incorporation of images from daily life into a series of vivid tableaux. Jarman created a huge database of images from which he constantly drew for both paintings and films. He was always writing down ideas and making drawings into a series of sketchbooks which provided him with the raw materials for his artistic products. Jarman's significance for this publication was that he united all aspects of his life into an aesthetic adventure. This included finding a signature as a gay artist who was also a passionate gardener. He also repudiated a literal or narrative structure and any idea of plot. This makes his work both difficult but rewarding.     

Beauty and Character: Values Beyond Beauty in Architecture

Formalist conceptions of aesthetic goals began to give way from the 17^th century on to rationalist accounts of experience. Beauty as described as essential by Renaissance thinkers was reconceived as just one possibility, with the sublime in Burke's account as another. In the early 20^th century Clive Bell again asserted a formalist position with his argument for significant form. The weakness of the formality position, and the need for a richer, more contextual account of aesthetic goals and experience is argued with reference to the idea of thick and thin concepts as applied by Bernard Williams to ethics, Wittgenstein's attention to the way in which language is used in a specific context, and Scruton's emphasis on an informed conception of the object of aesthetic attention. Beauty, in Alberti's procedural account if not in his version of the Platonic ideal, can be seen to continue to have critical value. The idea of character, however, offers a broader range of possibilities for experience and of goals for design.     

Mathematics knowledge for understanding and problem solving

Two important aspects of transfer in mathematics learning are the application of mathematical knowledge to problem solving and the acquisition of more advanced concepts, both in mathematics and in other domains. This paper discusses general assumptions and themes of current cognitive research on mathematics learning, focusing on issues of the understanding thought to facilitate transfer of mathematical knowledge. Two studies illustrating these themes are presented, one concerning students' understanding of numerical relationships involved in basic addition and subtraction combinations, the other dealing with students' understanding of algebraic expressions and transformations. Implications of these cognitive perspectives for instruction are discussed.     

The impact of financial aid on women's demand for higher education

The Educational Amendments of 1972 marked a new direction in public policy regarding the scope and purpose of financial aid to higher education. Aid became more student-oriented, and equality of opportunity for higher education became a goal. This empirical study with national longitudinal data has made a start in policy evaluation of the effect of the 1972 Educational Amendments on the higher education acquired by young women. The most important result of financial aid receipt for young women is that those who received aid averaged 0.64 more years completed of higher education and averaged .145 greater graduation probability than similar women who did not receive aid. These results were obtained in multiple regression models in which the effects of marital status, parental background, geographic locations and economic characteristics, and tuition level were controlled for. These results suggest that policy attempts to stimulate the higher education acquired by enrolled young women by increasing the availability of financial aid are well founded.     

Integrating control generated by positive and negative reinforcement on an operant baseline: Appetitive-aversive interactions

The interaction of opposing motivational states was measured within a design in which rats barpressed for food in one stimulus and to avoid shock in another. Tone and light discriminative stimuli (Sds) were counterbalanced over incentive conditions. Extinction eliminated responding when neither Sd was present. To minimize the influence of competing peripheral operants or reinforcer-elicited behaviors during appetitive-aversive interactions, contingency parameters were manipulated to generate similar rates and patterns of barpressing in both Sds and stimulus-compounding tests were administered in extinction. On these tests, rates in tone, light, and tone plus light (T+L) were equivalent. In contrast, when the same reinforcer (i.e., food or shock avoidance) maintained comparable training rates in tone and in light, in testing, T+L controlled double the rates of the single stimuli—strong additive summation. These results were strikingly similar to those of single-incentive experiments concerned with the contribution of excitatory and inhibitory incentive states to the results of stimulus compounding. Simultaneously presenting two Sds whose implicit stimulus-reinforcer (S-S^r) contingencies were arranged to make them, respectively, conditioned appetitive and aversive exciters (present experiment) produced test results comparable to those of two Sds whose implicit S-S^r contingencies were arranged to make them both conditioned inhibitors. Reciprocal antagonism between these two motive states more than neutralizes them. It appears to produce a negative (i.e., an inhibitory) motive state.     

AILEM Programme: a long‐term intervention to promote literacy learning in low‐performing primary schools in Chile

After one year of implementation, this paper describes a programme designed to support literacy learning in low performing schools from poor sectors in Santiago, Chile. School‐based intensive training on theory and practice of a literacy learning framework for classroom instruction and long‐term support were used to impact the achievement of students from disadvantaged families in 16 kindergarten classrooms and 16 1st‐grade classrooms in nine primary schools. Preliminary results showed an improvement in learning achievement positively related to level of implementation of the literacy instruction framework in the classrooms and teachers' perception of an improvement in their knowledge and classroom practices. Although findings from this study cannot support definite conclusions, because of the lack of experimental conditions, they provide relevant information for future experimental studies on how to meet the literacy learning needs of children from disadvantaged backgrounds.
