The book is made up of 21 chapters from 25 presentations at the 23rd MAVI conference in Essen, which featured Alan Schoenfeld as keynote speaker. Of major interest to MAVI participants is the relationship between teachers' professed beliefs and classroom practice. The first section is dedicated to classroom practices and beliefs regarding those practices, taking a look at prospective or practicing teachers' views of different practices such as decision-making, the roles of explanations, problem-solving, patterning, and the use of play. The focus of the second section in this book deals with teacher change, which is notoriously difficult, even when the teachers themselves are interested in changing their practice. The third section of this book centers on the undercurrents of teaching and learning mathematics, what rises in various situations, causing tensions and inconsistencies. The last section of this book takes a look at emerging themes in affect-related research. In this section, papers discuss attitudes towards assessment.

In search of a way to worship that is relevant today and into the twenty-first century, Moeller proposes an approach based on the "great commandment" to love God and one's neighbor as oneself. With special attention to the time, space, sounds, sights, touches, and symbols that form the context of every worship service, she argues for a collaborative approach to the worship service in which the participants are involved from preparation to celebration. Illustrating this highly evocative, thoroughly feminist theology of worship is a sample service that pays particular attention to how the process and design of worship impact the experience of the worshipers.

Die deutsche Burgschaft blickt auf eine lange Rechtstradition zuruck und ist Gegenstand zahlreicher Gerichtsurteile. Die kolumbianische fianza civil entspricht diesem Rechtsinstitut. Sie ist jedoch nicht so streitbehaftet wie die deutsche Burgschaft. Die vorliegende Publikation befasst sich mit der Frage, welche Rechtsordnung geeigneter auf das Spannungsverhaltnis zwischen dem Sicherungsinteresse des Glaubigers einerseits und dem Schutzinteresse des Burgen andererseits eingeht. Die Autorin eroertert dafur zunachst die generellen Unterschiede der Privatrechtsordnungen und geht sodann auf die einzelnen Facetten der Burgschaft vor dem Hintergrund der verschiedenen Gesetze ein. Diesbezuglich setzt sie sich kritisch mit den jeweiligen Vor- bzw. Nachteilen, welche die Normen bieten, auseinander.
