The Enterprise of Socratic Metaethics

That human beings have the potential for rationality and the ability to cultivate it is a fact of human nature. But to value rationality and its subsidiary character dispositions - impartiality, intellectual discrimination, foresight, deliberation, prudence, self-reflection, self-control - is another matter entirely. I am going to take it as a given that if a person's freedom to act on her impulses and gratify her desires is constrained by the existence of others' equal, or more powerful, conflicting impulses and desires, then she will need the character dispositions of rationality to survive. The more circumscribed one's freedom and power, the more essential to survival and flourishing the character dispositions of rationality and the spirit may become

The Developmental Path of the Lawyer

My mother does not drive, and I own a towel that I cannot use-these are my reasons for studying law. I am an integrated tapestry of elation and disappointment, risk and reward, ambiguity and conviction .. .. I discovered [through adversity] that transitional challenges were not permanent impediments to my progress, but were instead emboldening catalysts to my personal evolution and professional development. These two stories come from admissions essays submitted by members of Georgetown University Law Center\u27s class of 2014, recently published in the Law Center\u27s alumni magazine. The published essays provide fascinating views into the personal experiences and deep reflection that lead people to pursue legal studies

Towards an Intelligent Tutor for Mathematical Proofs

Computer-supported learning is an increasingly important form of study since it allows for independent learning and individualized instruction. In this paper, we discuss a novel approach to developing an intelligent tutoring system for teaching textbook-style mathematical proofs. We characterize the particularities of the domain and discuss common ITS design models. Our approach is motivated by phenomena found in a corpus of tutorial dialogs that were collected in a Wizard-of-Oz experiment. We show how an intelligent tutor for textbook-style mathematical proofs can be built on top of an adapted assertion-level proof assistant by reusing representations and proof search strategies originally developed for automated and interactive theorem proving. The resulting prototype was successfully evaluated on a corpus of tutorial dialogs and yields good results.Comment: In Proceedings THedu'11, arXiv:1202.453

Modelling human teaching tactics and strategies for tutoring systems

One of the promises of ITSs and ILEs is that they will teach and assist learning in an intelligent manner. Historically this has tended to mean concentrating on the interface, on the representation of the domain and on the representation of the student’s knowledge. So systems have attempted to provide students with reifications both of what is to be learned and of the learning process, as well as optimally sequencing and adjusting activities, problems and feedback to best help them learn that domain. We now have embodied (and disembodied) teaching agents and computer-based peers, and the field demonstrates a much greater interest in metacognition and in collaborative activities and tools to support that collaboration. Nevertheless the issue of the teaching competence of ITSs and ILEs is still important, as well as the more specific question as to whether systems can and should mimic human teachers. Indeed increasing interest in embodied agents has thrown the spotlight back on how such agents should behave with respect to learners. In the mid 1980s Ohlsson and others offered critiques of ITSs and ILEs in terms of the limited range and adaptability of their teaching actions as compared to the wealth of tactics and strategies employed by human expert teachers. So are we in any better position in modelling teaching than we were in the 80s? Are these criticisms still as valid today as they were then? This paper reviews progress in understanding certain aspects of human expert teaching and in developing tutoring systems that implement those human teaching strategies and tactics. It concentrates particularly on how systems have dealt with student answers and how they have dealt with motivational issues, referring particularly to work carried out at Sussex: for example, on responding effectively to the student’s motivational state, on contingent and Vygotskian inspired teaching strategies and on the plausibility problem. This latter is concerned with whether tactics that are effectively applied by human teachers can be as effective when embodied in machine teachers

How the Conception of Knowledge Influences Our Educational Practices: Toward a Philosophical Understanding of Epistemology in Education

This paper explores how the conception and valuation of the knowledge within our educational practices determines the planning, writing, and implementation of the curriculum. There is a pressing need for educators to philosophically and systematically understand the relationship between the foundational epistemological beliefs that ground a curriculum and its relationship to forming the notions of competency, pedagogy, and the methods for evaluating and assessing student progress. These issues are not only relevant, but crucial when attempting to justify a particular conception of education, which relates directly to the student\u27s potential for intellectual growth and social development. It may be argued that the comprehensive theory of curriculum planning manifests the intersection of philosophical critique, social inquiry, and psychological theory, and the author believes that bringing philosophy, and a formal methodology, to bear on the problems of education represents an instance where philosophy might contribute in a direct manner to the active and ongoing process of current educational reform

Using Computational Agents to Design Participatory Social Simulations

In social science, the role of stakeholders is increasing in the development and use of simulation models. Their participation in the design of agent-based models (ABMs) has widely been considered as an efficient solution to the validation of this particular type of model. Traditionally, "agents" (as basic model elements) have not been concerned with stakeholders directly but via designers or role-playing games (RPGs). In this paper, we intend to bridge this gap by introducing computational or software agents, implemented from an initial ABM, into a new kind of RPG, mediated by computers, so that these agents can interact with stakeholders. This interaction can help not only to elicit stakeholders' informal knowledge or unpredicted behaviours, but also to control stakeholders' focus during the games. We therefore formalize a general participatory design method using software agents, and illustrate it by describing our experience in a project aimed at developing agent-based social simulations in the field of air traffic management.Participatory Social Simulations, Agent-Based Social Simulations, Computational Agents, Role-Playing Games, Artificial Maieutics, User-Centered Design

Designing for tacit learning: an investigation of design strategies for multimedia supported learning in the crafts

There is an increasing interest and activity in the design of interactive multimedia to support learning in all fields of education and training. However, most of the theory to support such developments is concerned with learning explicit knowledge and there is little guidance available to designers of material for learning in areas with an element of tacit knowledge such as craft skills. This paper describes the foundation work for a long-term project concerned with learning in traditional rural crafts but with the intention to provide a methodological framework for the design of multimedia-based learning in all areas of craft knowledge. A review of established theory of learning and the use of multimedia for learning in areas of explicit knowledge indicates some important basic principles, for example the need to understand the interaction between the teacher and learner in the context of the subject being taught and the need for clear narrative structures to avoid students becoming "lost" in the multiple pathways of interactive media. Observational studies of learning using educational video in a craft context and a study of an experienced craftsman/teacher teaching a group of learners, complemented by study of learning in related contexts, have allowed problems and issues to be identified and design strategies to be developed. While these are provisional they provide an overview of the design problems and have been used to plan a programme of experimental design and evaluation to test and develop principles of effective multimedia design for craft learning. </p

Early Greek Thought and Perspectives for the Interpretation of Quantum Mechanics: Preliminaries to an Ontological Approach

It will be shown in this article that an ontological approach for some problems related to the interpretation of Quantum Mechanics could emerge from a re-evaluation of the main paradox of early Greek thought: the paradox of Being and non-Being, and the solutions presented to it by Plato and Aristotle. Plato's and Aristotle's systems are argued here to do on the ontological level essentially the same: to introduce stability in the world by introducing the notion of a separable, stable object, for which a principle of contradiction is valid: an object cannot be and not-be at the same place at the same time. After leaving Aristotelian metaphysics, early modern science had to cope with these problems: it did so by introducing ``space'' as the seat of stability, and ``time'' as the theater of motion. But the ontological structure present in this solution remained the same. Therefore the fundamental notion `separable system', related to the notions observation and measurement, themselves related to the modern concepts of space and time, appears to be intrinsically problematic, because it is inextricably connected to classical logic on the ontological level. We see therefore the problems dealt with by quantum logic not as merely formal, and the problem of `non-locality' as related to it, indicating the need to re-think the notions `system', `entity', as well as the implications of the operation `measurement', which is seen here as an application of classical logic (including its ontological consequences) on the material world.Comment: 18 page

African Sage Philosophy and Socrates: Midwifery and Method

The paper explores the methodology and goals of H. Odera Oruka’s sage philosophy project. Oruka interviewed wise persons who were mostly illiterate and from the rural areas of Kenya to show that a long tradition of critical thinking and philosophizing exists in Africa, even if there is no written record. His descriptions of the role of the academic philosopher turned interviewer varied, emphasizing their refraining from imposition of their own views, their adding their own ideas, or their midwifery in helping others give birth to their own ideas. The accuracy and consistency of the various metaphors used by Oruka is the main focus of the article’s analysis. The article sums up the shortcomings of Oruka’s method as well as its strengths and concludes with Oruka’s challenge to academic philosophers to rethink their own roles in society

The Effect of Dialogic Teaching on Students’ Critical Thinking Disposition

AbstractThis study sought to identify the effect of dialogic teaching methods (group discussion and Socratic dialogue) on university students’ critical thinking disposition and social interaction. The study was based on qualitative approach using action research methodology. Participants were comprised of two groups of undergraduate students in the field of education who were selected by purposeful sampling (N=40). Data was collected using standardized open-ended interview. The interview was organized in three main themes (evaluation of the education, evaluation of the interactions and the overall evaluation), and the systematic sequence of seven questions. After designing implementing patterns(group discussion and Socratic dialogue), based on topics covered in educational psychology, both methods were used in one semester, followed by interviews with participants from both groups, conducted by the researcher at the end of semester. In order to find constructs, the data collected from the interviews were analyzed using “interpretational analysis.” The results indicated the effectiveness of dialogic teaching methods in improving six elements of critical thinking dispositions (analyticity, cognitive maturity, CT self-confidence, self evaluation, open- mindedness, truth-seeking), and seven elements of social interaction (knowing each other, friendship and intimacy, tendency to dialogue, responsibility, class dynamism, interaction with teacher, intimacy with the instructor)
