Children's ideas about the reliability of experimental data

This paper reports some of the findings of the Procedural and Conceptual Knowledge in Science (PACKS) project. It documents children's ides about the reliability of experimental data, an important element of their understanding of science procedures. These ideas were elicited using a written survey instrument completed by over 1000 students aged 11, 14 and 16, chosen to be representative of the full ability range. The results show progression with age in understanding of empirical data. A range of ideas about the function of repeat measurements, how to handle repeat measurements and anomalous readings, and the significance of the spread of a set of repeated measurements emerge and are discussed.     

Conceptualizing curriculum management in an effective secondary school: a Western Australian case study

ABSTRACT

This paper investigates the linkages between management processes and the curriculum using an academically effective secondary school as a case study. The aims of the study are twofold. First, in view of the acknowledged importance governments and others place on the quality of school leadership and management on the one hand and curriculum, teaching and learning reforms on the other, there is a need for empirical data as to how school leaders and managers work to secure improvements in curriculum, teaching and learning. This study purports to provide such data. The second aim acknowledges the need to develop conceptual frameworks and data collection instruments as aids to better understanding of complex relationships within school organizations.two deputy principals do play an indirect and important part in promoting academic performance by reinforcing school values in a wide variety of ways. Third, curriculum management is the responsibility of senior teachers and there is tight linkage between both senior teachers and teachers and high quality teaching and learning. Finally, the loose linkage between departments, and also between departments and senior management, provides little opportunity for a school‐wide approach to curriculum matters. It is evident that a whole‐school curriculum management perspective is absent in this school.
