Limits Of Truth: Exploring Epistemological Approaches To Argumentation, Michael H.G. Hoffmann Jan 2005

Limits Of Truth: Exploring Epistemological Approaches To Argumentation, Michael H.G. Hoffmann

Michael H.G. Hoffmann

Some proponents of epistemological approaches to argumentation (Biro, Siegel, Lumer, Goldman) assume that it should be possible to develop non-relative criteria of argument evaluation. By contrast, this paper argues that any evaluation of an argument depends (a) on the cognitive situation of the evaluator, (b) on background knowledge that is available for this evaluator in a certain situation, and (c)—in some cases—on the belief-value-system this person shares.


Logical Argument Mapping: A Method For Overcoming Cognitive Problems Of Conflict Management, Michael H.G. Hoffmann Jan 2005

Logical Argument Mapping: A Method For Overcoming Cognitive Problems Of Conflict Management, Michael H.G. Hoffmann

Michael H.G. Hoffmann

A crucial problem of conflict management is that whatever happens in negotiations will be interpreted and framed by stakeholders based on their different belief-value systems and world views. This problem will be discussed in the first part of this article as the main cognitive problem of conflict management. The second part develops a general semiotic solution of this problem, based on Charles Peirce's concept of "diagrammatic reasoning." The basic idea is that by representing one 's thought in diagrams, the conditions that determine interpretations can become visible, we can "experiment" with them, and we can change them eventually. The ...


Examining The Use Of Computer Simulations To Promote Learning Of Electrochemistry Among College Students , Han-Chin Liu Jan 2005

Examining The Use Of Computer Simulations To Promote Learning Of Electrochemistry Among College Students , Han-Chin Liu

Retrospective Theses and Dissertations

When computer simulations are popular in helping students understand chemistry in today's classrooms, it is important to realize how instructional use of computer simulations affects students' understanding of science. This dissertation centers around the impact of the use of computer simulations on college students' learning. Chapter 1 generally addresses the background and the significance of the research topics. Chapter 2 reviews the literature from research that studied the factors that affect the use of computer simulations in helping students learn science. Learners were found to understand science theories better with descriptions and explanations presented in both verbal and visual ...


Impact Of Available Interactivity Options On Student Learning And Discussions In Online Physics Courses , Deanna L. Snyder Poudel Jan 2005

Impact Of Available Interactivity Options On Student Learning And Discussions In Online Physics Courses , Deanna L. Snyder Poudel

Retrospective Theses and Dissertations

Community colleges are offering more online courses to meet the demands of the students they serve. To make these courses effective learning experiences, instructors are trying to utilize technologies and strategies to bring distance students into a virtual community where learning can best take place. This study examines the impact of adding a virtual class lecture/discussion and virtual office hours to two online physics courses offered through an urban community college. Two different courses were taught with two sections each. One section of each course added the virtual sessions for up to 4 hours per week. Effects studied include ...

The Iowa Chemistry Education Alliance, Icea: Process And Product , Kathleen Annette Burke

Retrospective Theses and Dissertations

The Iowa Chemistry Education Alliance, ICEA, supported by Department of Education Star Schools funding (R203F5000198), was both a Process and a Product.;The Process included: (a) Design and support of high school teacher training sessions that incorporated distance learning techniques, cooperative learning and guided inquiry strategies, and a constructivist, student-centered classroom focus; (b) Design and incorporation of eight supplemental learning modules, corresponding assessment rubrics, and supporting videotapes into the existing Iowa high school chemistry curriculum; (c) Adaptation of the learning modules throughout the course of the academic year while the units were being integrated into the existing curriculum; (d) Modification ...


Problem-Based Learning In An On-Line Biotechnology Course , James Daniel Cheaney Jan 2005

Problem-Based Learning In An On-Line Biotechnology Course , James Daniel Cheaney

Retrospective Theses and Dissertations

Problem-based learning (PBL) is a pedagogical tool that uses a "real world" problem or situation as a context for learning. PBL encourages student development of critical thinking skills, a high professional competency, problem-solving ability, knowledge acquisition, the ability to work productively as a team member and make decisions in unfamiliar situations, and the acquisition of skills that support self-directed life-long learning, metacognition, and adaptation to change. However, little research has focused on the use of PBL in on-line "virtual" classes. We conducted two studies exploring the use of PBL in an on-line biotechnology course. In the first study, ethical, legal ...


What You Should Know To Survive In Knowledge Societies. On A Semiotic Understanding Of 'Knowledge', Michael H.G. Hoffmann Dec 2004

What You Should Know To Survive In Knowledge Societies. On A Semiotic Understanding Of 'Knowledge', Michael H.G. Hoffmann

Michael H.G. Hoffmann

Different situations - like school and workplace - demand different forms of knowledge. Even more important, in particular for lifelong learning, are forms of knowledge we need for managing movements between those situations. To develop a better understanding of how to 'navigate' knowledge boundaries, this paper analyzes, firstly, interviews with scientists interpreting familiar and unfamiliar graphs. Our goal is to identify those forms of knowledge that should receive special attention in education. Secondly, the article elaborates - based on Peirce's semiotic - an epistemologically reflected semiotic model to describe the role and conditions of knowledge.
