the purpose of this paper is to describe the results of a photovoice evaluation of a robotics and programming project for prekindergarten (RAPP). RAPP researchers developed and implemented the program at three urban childcare centers in six teacher's classrooms. All of the teachers of prekindergarteners and rising prekindergarteners had opportunities to use the robot, KIBO, during implementation. Photovoice, using ten RAPP teachers, provided visual images as evidence and promoted sharing knowledge and experiences. Teachers submitted photographs of their children engaging with KIBO and participated in two discussions withtheir researcher concerning the pictures. At both times, the discussions were audio recorded and summarized. Researchers concept mapped the interviews to identify and communicate common themes. In order of importance to the teachers, the children when using KIBO were engaged, worked independently of the teachers and cooperatively with classmates, were persistent, learned academic knowledge and skills, and developed problem solving skills.

Politics and Religion are traditionally taboo topics in polite after-dinner conversation. In this panel, we are going to discuss taboo topics in agile software development. Technical teams ought to choose technology based on the immediate needs of the current project and organization. But we all know that technology and methodology choices are often driven by people enhancing their resume - this conflict can start religious wars! On agile projects, we ask our customers to prioritize stories purely by business value, as if this is a straightforward thing to do and company politics are irrelevant. We need to recognize that projects that only deliver working software can still be classed as failures from an organizational perspective. If we pretend that the political dimension does not exist on agile projects then we cannot develop and share practices that help us handle these situations. this panel brings industry professionals to share their perspectives and experiences, the audience should come prepared to both ask and answer questions.

this paper(1) takes a look at how XP and other agile practices can improve a software process for the development of avionics software. Developers of mission critical airborne software are heavily constrained by the RTCA DO-178B regulations [8]. these regulations impose strict rules regarding traceability and documentation that make it extremely hard to employ an iterative software development process. In particular, the extra validation overhead increases the time spent on small iteration cycles (for example, a bug-fix) to several weeks. Currently, this sector is also pressed to switch to a more agile, customer driven approach. In this paper we investigate how to speed up development and cope with changing requirements using agile techniques. the research was carried out in cooperation with Barco, a major Belgian avionics equipment supplier. We explain why certain agile techniques have less effect as the project progresses. We point out the stadia in which each XP practice is beneficial and where XP practices might cause a slowdown.
