This paper addresses contributions that dynamic geometry systems (DGSs) may give in reasoning by contradiction in geometry. We present analyses of three excerpts of students' work and use the notion of pseudo object, elaborated from previous research, to show some specificities of DGS in constructing proof by contradiction. In particular, we…

Logical reasoning skills are important for a successful mathematical learning and in students' future career. These skills are essential for a primary school teacher, because they need to explain solving methods and solutions to their pupils. In this research we studied pre-service primary school teachers' logical reasoning skills. The results…

The present study explores the use of conjunctions in simple versus complex argumentative tasks performed by second language (L2) learners as a specific measure for the amount of reasoning involved in task performance. The Cognition Hypothesis (Robinson, 2005) states that an increase in cognitive task complexity promotes improvements in L2…

The Mock Trial is an experiential exercise adapted from a law school process that encourages students to think critically about theories, topics, and the practice of management in an innovative classroom experience. Playing the role of attorneys and witnesses, learners ask questions and challenge assumptions by playing roles in a trial with…

The aim of this study is to describe and analyse the writing discourse in one classroom and how students learn through studying a topic, i.e. the teaching and learning of written argument. The study takes its stance from a sociocultural perspective and is influenced by discourse analyses, new literacy studies and critical literacy (Fairclough…

The purpose of this study was to investigate the shift of Thai teachers' views of learning and their pedagogical practices from the traditional approach to be more centered on an argument-based inquiry approach (ABI) in Thai classrooms, where teachers and learners have long been familiar with the lecture-based tradition. Other than examining the…

The purpose of this study was to identify and describe teaching actions--embedded in the "Science Writing Heuristic approach," a systematic teaching approach that integrates literacy instruction and argument-based inquiry learning of science--supportive of the cross-disciplinary literacy expectations necessary to compete in the 21st…

This report summarizes the personal epistemology and self-efficacy concepts and how they affect special education teachers. This report is based on the social cognitive theory, perceived and collective efficacy, and how the conceptual thoughts of a special education teacher affect their instructional focus in the classroom. Self-efficacy beliefs…

As one of the foundations of persuasion, fallacies should be included in the teaching of persuasive speaking. It is important that speakers avoid misleading their audience as they have an ethical responsibility to tell the truth and avoid misleading information. If discovered, fallacies in messages can damage the credibility of the speaker and…

The purpose of this article was to describe the task design and implementation of cultural artefacts in a mathematics lesson based on the integration of modelling and conjecturing perspectives. The conceived process of integrating a soccer ball into mathematics lessons via modelling- and conjecturing-based instruction was first detailed. Next, the…

The paper examines how the tensions of corporate responsibility are articulated and reconciled in a controversial situation of a foreign investment. We conducted a conventionalist analysis on the company press releases in a case where a Finnish forest industry company invested in a pulp mill in South America. The findings show that the use of…

In this article I compare the lines of argumentation that are used in two public debates about the introduction of national canons in Sweden and the Netherlands. These arguments illustrate how different political actors understand the balance they think should be struck between the interests of individual children and society in obtaining social…

The purpose of this study was to compare the perceptions of American and international students on conflict resolution, and to determine if the students were willing to participate in conflict resolution. A survey was given to 226 students at an eastern university that asked them to identify a major international conflict and whether they felt…

In late 1939, the United States Bureau of the Census was gearing up for the 16th official enumeration, or count, of the nation's population. Authorities wanted to insure widespread participation. So, they made good use of some information revealed in the 1930 Census--namely that roughly 40 percent of American households had a radio set. In…

This dissertation examines theories of emotion in politically contentious discourse in order to better understand the implications for teachers and students in composition classrooms where critical pedagogical practices lead to contentious political work. I suggest that partly as a result of the social and political turn in composition studies,…
