Developing Deleuze and Guattari's concepts of territorialization and the apparatus of capture, this article explores the role that Sri Lankan Hindu temples have played in the formation of ethnicity and ethnic conflict. Analyzing three contemporary events, the article introduces ways in which many different Sri Lankans (Sinhalese and Tamil) interpret their country's predicament and seek to resolve or prolong it. The events also reveal how scholarship becomes entangled in ethnic nationalism. I then examine in greater detail a village in which temple construction was a critical feature of identity formation during the creation of Sri Lanka as a colonialist and capitalist bureaucratic space. Through this account, I argue that the formation of polarized ethnicity in Sri Lanka is the product of multiple refractive forces, of which temples are one, and not the end result of a singular colonialist bureaucratic agency.

Astronomy is one of the recurrent contemporary issues in the mass media where news related to comets, new stars, satellites, space tests, etc., frequently appear. Through this media presence students develop an interest in learning about aspects of astronomy. However, the information students gain from various sources, both inside and outside the classroom, doesn't often increase their knowledge about the most basic and common aspects of astronomy (Martinez Pena & Gil Quilez, 2001). Studies that have explored students' and teachers' understandings of astronomical concepts (Kalkan et al, 2007; Trumper, 2001) have found many alternative conceptions relating to basic astronomical processes such as day and night, the seasons, gravity and the relative distances between celestial objects.

The research described in this paper argues that difficulties of leaming science concepts such as those associated with processes involving the Sun, Moon and Earth, such as day and night, the seasons and phases of the moon, are fundamentally representational in nature. There is a need for learners to use their own representational, cultural and cognitive resources to engage with the subject-specific representational practices of science. From this perspective students need to understand and conceptually integrate different representational modalities or forms in learning science and reasoning in science. The researchers worked with two experienced teachers in planning a teaching sequence in astronomy using a teaching approach that highlight representational issues and options in helping students explore and develop key conceptual understandings. Classroom sequences involving the two teachers were videotaped using a combined focus on the teacher and groups of students. Video analysis software was used to capture the variety of representations used, and sequences of representational negotiation. From a pedagogical perspective the representational approach placed a significant agency in the hands of students which resulted in structured discussions around conceptual problems. Representations were used as tools for reasoning and communication to drive classroom discussions and develop higher levels of understanding in the students. The pre- and post-testing showed significant gains in students thinking from naive to more scientific understandings of astronomy.

This portfolio represent an ongoing investigation into relationships between art and astronomy with particular reference to photographic imaging of the cosmos and how such imaging has influenced the mapping and modelling of the universe. I am also interested in the subjective interpretation of astronomical observations and the point at which such images fail to represent, ie, the blurred image, which may represent the limits of technology as well and opening the possibility for metaphorical readings and imaginings on the part of the observer.
