Responding to external accountability in high-performing,high-capacity public secondary schools in Chile

The qualitative study on which this article reports explored how senior leaders, mathematics and Spanish language teachers (N = 72) in four high-performing, high-poverty, public secondary schools in Chile enact performance-based accountability policies related to standardised assessments. These four public schools were selected because prior to when the study was conducted all were part of the Bicentennial Schools Programme led by the Ministry of Education from 2010 to 2014. The aim of the programme was to develop effective secondary schools to serve low-income students. A thematic analysis of data produced through individual and group interviews and observations of departmental meetings shows that the enactment of performance-based accountability involved two dimensions of learning-centred leadership, distributed among senior leaders and department heads. An aim shared by parents, students, teachers and senior leaders was to ensure students' access to, and completion of, studies in higher education. Attaining good scores in national standardised SIMCE tests was key to meeting the vision. Collective trust among all actors and macro level trust in standardised testing served as a resource for strong collaboration to improve instruction and learning as well as teachers' collective efficacy. The discussion focuses on school-level practices and policy-level decisions that create conditions for the effective use of information produced from standardised assessments. A key point supported by our findings is that successful performance in external assessments is resourced by, and fosters, trust formation in schools.     

High pressure research on materials

In this article, different methods for generating and measuring high pressure are described. Empirical equations of state (EOS) are illustrated for some standard materials. P Ch Sahu (left) is at the Materials Science Division of Indira Gandhi Centre for Atomic Research, Kalpakkam. He is a specialist in the field of high pressure science and is presently heading this activity at his institute. His primary research areas are in high pressure phase transitions and in synthesis and study of novel materials under extreme pressure and temperature conditions.     

Mathematics education as a ‘design science’

Mathematics education (didactics of mathematics) cannot grow without close relationships to mathematics, psychology, pedagogy and other areas. However, there is the risk that by adopting standards, methods and research contexts from other well-established disciplines, the applied nature of mathematics education may be undermined. In order to preserve the specific status and the relative autonomy of mathematics education, the suggestion to conceive of mathematics education as a design science is made.Revised and extended version of the paper Mathematikdidaktik als design science, published inJournal für Mathematikdidaktik 13 (1992), 55–70.

The effects of cultural and historical information and contribution threshold on public contributions: an experimental study on the conservation of heritage houses in Penang,Malaysia

Budget constraints at the local government level towards the provision of public goods have fuelled interest in the voluntary contribution and provision point mechanisms. However, due to their public nature, these mechanisms are not without problems. The literature shows the presence of free riding and socially inefficient contribution levels. This paper experimentally tests the effect of cultural and historical information pertaining to heritage houses in Penang, Malaysia, on public contributions for their conservation. This paper considers a standard linear one-shot four-person public good game and the decision of the subjects being to contribute either to a private or to a public account. We devise 4 treatments: a Control treatment, a treatment where subjects are provided with cultural and historical information pertaining to the heritage houses, a treatment that includes a contribution threshold, and finally a treatment that combines the use of cultural and historical information with the contribution threshold. The main finding shows that 60–75 % of the subjects contributed more than what they believed others in the same group would contribute when they were provided with the pertinent cultural and historical information. Most of the subjects contributed less than their belief, while 75–77 % cooperated ‘selfishly’ in treatments without the information. These findings are in agreement with the literature, namely that contributions are higher in treatments with a contribution threshold. Moreover, the combination of a contribution threshold and cultural information could encourage more pro-social behaviours.
