In this paper we present the argument-based model proCLAIM, intended to provide a setting for heterogeneous agents to deliberate over safety critical actions. To achieve this purpose proCLAIM features a Mediator Agent with three main tasks: (1) guiding the participating agents in what their valid dialectical moves are at each stage of the dialogue; (2) deciding whether submitted arguments should be accepted on the basis of their relevance; and finally, (3) evaluating the accepted arguments in order to provide an assessment of whether the proposed action should or should not be undertaken. The main focus in this paper is the proposal of a set of reasoning patterns, represented in terms of argument schemes and critical questions, intended to automatise deliberations on whether a proposed action can safely be performed. We aim to motivate the importance of these schemes and critical questions for: (a) the Mediator Agent's guiding task that allows for a highly focused deliberation; (b) the effective participation of heterogeneous agents; and (c) enabling the reuse of previous similar deliberations in order to evaluate arguments on an evidential basis.

Bu çalışmanın amacı, GeoGebra ve Kağıt-Kalem gruplarında geometri soruları çözen ortaokul matematik öğretmen adaylarının argümantasyon yapılarının doğasını incelemektir. Bu çalışmada nitel durum çalışması deseni kullanılmış ve veriler 2013-2014 akademik yılının sonbahar döneminde 16 ortaokul matematik öğretmen adayından toplanmıştır. Veri kaynaklarını uygulamaların video kayıtları, odak grup görüşmeleri ve belgeler oluşturmaktadır.Bulgularda beş çeşit global argümantasyon yapısı ortaya çıkmıştır. Bunların ikisi Çizgi/Hat yapı ve Bağımsız-Argümanlar yapısı bu çalışmada ortaya çıkmıştır. Ayrıca katılımcılar 9 çeşit lokal argüman yapılarından üçünü çok sık kullanmayı tercih etmişlerdir. Son olarak, katılımcıların gerekçelendirmelerine odaklanarak lokal argümantasyonları incelenmiştir. Bu analiz, ortaokul matematik öğretmen adaylarının GeoGebra ve Kağıt-Kalem gruplarında geometri soruları çözerken kullandıkları lokal argümantasyonların niteliğini ortaya çıkarmıştır. The purpose of the current study was to investigate the nature of argumentation structures of prospective middle school mathematics teachers while solving geometry tasks within the GeoGebra and Paper-Pencil groups. The study employed qualitative case study design and the data of which were collected from 16 prospective middle school mathematics teachers during the fall semester of the 2013-2014 academic year. Data were based on the video recordings of the implementations, the focus group interviews and documents.The findings revealed five types of global argumentation structures, two of which emerged from the present study: Line-structure and Independent-Arguments structure. In addition, the participants employed 9 types of local arguments while three of them were most frequently preferred. Finally, the local argumentations were examined by focusing on the justifications of the participants. This analysis revealed the characteristics of the local argumentations that prospective middle school mathematics teachers use while solving geometry tasks in GeoGebra and Paper-Pencil groups. 318
