Reimagining school libraries : children's perspectives and new opportunities

The Federal Government’s recent Building the Education Revolution program resulted in, among other features, the creation of over 600 new school libraries in Queensland alone. This paper reports on a component of a research project carried out with students in six primary schools and one secondary school that benefitted from the program, investigating the influences of these new physical environments on learning and teaching. In particular, this paper discusses one missing voice from the design process - that of the students who would be key users of the newly-created spaces in those schools. While opportunities for real involvement in design were minimal for most potential users of the new spaces, students’ imagined possibilities for school libraries, as submitted to the research project, suggest that students could have contributed different perspectives to enhance learning engagement through imaginative design elements. The findings of the project have relevance for teachers and teacher librarians in reconsidering the ways in which the new learning spaces are used as well as informing school designers in planning engaging school facilities. The findings may be extrapolated to the design and planning of general classrooms and other learning environments.

Teaching adult literacy : principles and practice.

Ofrece orientación sobre cómo trabajar con estudiantes adultos para desarrollar en ellos las habilidades en la alfabetización y en la práctica; además, supera la visión negativa de considerar a los alumnos adultos como 'problemas sociales' y con déficits de atención, pues se considera que sus aptitudes y recursos en muchos ámbitos de la vida son aprovechables en el proceso de aprendizaje. Incluye muchas teorías e investigaciones sobre la alfabetización de adultos, así como nuevas perspectivas teóricas y aplicaciones a la práctica cotidiana. Algunas de sus características son: aplicación de la teoría lingüística a la enseñanza de la alfabetización; ejemplos de escritura de estudiantes con comentario y análisis, sugerencias prácticas de enseñanza, planificación y evaluación; orientaciones para apoyar a los alumnos con dislexia y dificultades de aprendizaje global.

Structural analogues of the natural products magnolol and honokiol as potent allosteric potentiators of GABA(A) receptors.

Biphenylic compounds related to the natural products magnolol and 4'-O-methylhonokiol were synthesized, evaluated and optimized as positive allosteric modulators (PAMs) of GABA(A) receptors. The most efficacious compounds were the magnolol analog 5-ethyl-5'-hexylbiphenyl-2,2'-diol (45) and the honokiol analogs 4'-methoxy-5-propylbiphenyl-2-ol (61), 5-butyl-4'-methoxybiphenyl-2-ol (62) and 5-hexyl-4'-methoxybiphenyl-2-ol (64), which showed a most powerful potentiation of GABA-induced currents (up to 20-fold at a GABA concentration of 3μM). They were found not to interfere with the allosteric sites occupied by known allosteric modulators, such as benzodiazepines and N-arachidonoylglycerol. These new PAMs will be useful as pharmacological tools and may have therapeutic potential for mono-therapy, or in combination, for example, with GABA(A) receptor agonists.
