Attracting Black Male Students To Research Careers In Education: A Report From The Grad Prep Academy Project, Shaun R. Harper, Ph.D., Andrew C. Porter, Ph.D. Jan 2012

Attracting Black Male Students To Research Careers In Education: A Report From The Grad Prep Academy Project, Shaun R. Harper, Ph.D., Andrew C. Porter, Ph.D.

Shaun R. Harper, Ph.D.

This report is about the University of Pennsylvania’s Grad Prep Academy, a project that prepares Black undergraduate men for graduate study and research-related careers in the field of education. The project is also a longitudinal research study that enables us to analyze Black men’s trajectories from undergraduate study through graduate degree programs and eventually into their careers. Eighteen students participated in our first two cohorts of Academy Scholars. The project described in this report, as well as the recommendations we offer, can be instructive for other schools of education and a range of stakeholders who are concerned about the diversity …

Cognitive Effects Of Argument Visualization Tools, Michael H.G. Hoffmann Jan 2011

Cognitive Effects Of Argument Visualization Tools, Michael H.G. Hoffmann

Michael H.G. Hoffmann

External representations play a crucial role in learning. At the same time, cognitive load theory suggests that the possibility of learning depends on limited resources of the working memory and on cognitive load imposed by instructional design and representation tools. Both these observations motivate a critical look at Computer-Supported Argument Visualization (CSAV) tools that are supposed to facilitate learning. This paper uses cognitive load theory to compare the cognitive efficacy of RationaleTM 2 and AGORA.

Karl M Lorenz

A obra apresenta um panorama do ensino de Ciências no Brasil no século XIX, por meio da análise de livros didáticos utilizados no ensino secundário. Toma como referência os compêndios adotados no Colégio de Pedro II, por ser esta a instituição modelo para o ensino secundário público oitocentista no Brasil. Para melhor compreender o significado destas obras, que foram identificadas em programas de ensino que correspondem às reformas educacionais efetuadas pelo Governo Central de 1838 a 1898, o autor insere seu trabalho em uma discussão maior sobre o desenvolvimento histórico das Ciências Naturais e do ensino das Ciências no Colégio …


“Theoric Transformations” And A New Classification Of Abductive Inferences, Michael H.G. Hoffmann Jan 2010

“Theoric Transformations” And A New Classification Of Abductive Inferences, Michael H.G. Hoffmann

Michael H.G. Hoffmann

Based on a definition of “abductive insight” and a critical discussion of G. Schurz’s (2008) distinction of eleven “patterns of abduction” that he organizes in four groups, I suggest an even more comprehensive classification that distinguishes 15 forms in an alternative structure. These forms are organized, on the one hand, with regard to what is abductively inferred—singular facts; types; laws; theoretical models; or representation systems—and, on the other, with regard to the question whether the abductive procedure is selective or creative (including a distinction between “psychologically creative,” as in school learning, or “historically creative”). Moreover, I argue that theoretical-model abduction—which …

Learning From People, Things, And Signs, Michael H.G. Hoffmann Jan 2007

Learning From People, Things, And Signs, Michael H.G. Hoffmann

Michael H.G. Hoffmann

Starting from the observation that small children can count more objects than numbers—a phenomenon that I am calling the “lifeworld dependency of cognition”—and an analysis of finger calculation, the paper shows how learning can be explained as the development of cognitive systems. Parts of those systems are not only an individual's different forms of knowledge and cognitive abilities, but also other people, things, and signs. The paper argues that cognitive systems are first of all semiotic systems since they are dependent on signs and representations as mediators. The two main questions discussed here are how the external world constrains and …


The Complementarity Of A Representational And An Epistemological Function Of Signs In Scientific Activity, Michael H.G. Hoffmann, Wolff-Michael Roth Jan 2007

The Complementarity Of A Representational And An Epistemological Function Of Signs In Scientific Activity, Michael H.G. Hoffmann, Wolff-Michael Roth

Michael H.G. Hoffmann

Signs do not only “represent” something for somebody, as Peirce’s definition goes, but also “mediate” relations between us and our world, including ourselves, as has been elaborated by Vygotsky. We call the first the representational function of a sign and the second the epistemological function since in using signs we make distinctions, specify objects and relations, structure our observations, and organize societal and cognitive activity. The goal of this paper is, on the one hand, to develop a model in which both these functions appear as complementary and, on the other, to show that this complementarity is essential for the …


First Experiences With Object Lessons In Nineteenth-Century Brazil: Origins Of A Progressive Pedagogy For The Brazilian Primary School [Primeiras Experiências Com O Ensino Por Objetos No Brasil Oitocentista: Origens De Uma Pedagogia Progressiva Para A Escola Primaria Brasileira], Karl M. Lorenz, Ariclê Vechia Apr 2005

First Experiences With Object Lessons In Nineteenth-Century Brazil: Origins Of A Progressive Pedagogy For The Brazilian Primary School [Primeiras Experiências Com O Ensino Por Objetos No Brasil Oitocentista: Origens De Uma Pedagogia Progressiva Para A Escola Primaria Brasileira], Karl M. Lorenz, Ariclê Vechia

Karl M Lorenz

This paper describes the methodology of Object Teaching and relates how its appearance in Brazil was a transnational phenomenon that achieved its maximum articulation in 1886 with Rui Barbosa’s translation of Norman Calkins’ Primary Object Lessons. It begins with an overview of primary school teaching in Brazil in the second half of the 19th century, followed by discussion of Barbosa’s ideas on promoting change in the schools. Central to the exposition are the ideas contained in a report that Barbosa submitted to the National Assembly in 1882, in which he proposed a new organization of primary school education, suggestions for …


A Reforma Do Ensino De Ciências No Ensino Secundário Brasileiro Nas Décadas De 1960 E 1970 [Science Education Reform In Brazilian Secondary Schools In The 1960s And 1970s], Karl M. Lorenz Jan 2005

A Reforma Do Ensino De Ciências No Ensino Secundário Brasileiro Nas Décadas De 1960 E 1970 [Science Education Reform In Brazilian Secondary Schools In The 1960s And 1970s], Karl M. Lorenz

Karl M Lorenz

Na segunda metade do século dezoito, foi transplantado para o Brasil um paradigma que focalizava no processo da investigação científico no ensino das Ciências Naturais na escola secundária. O paradigma teve origem nos Estados Unidos em resposta às criticas internas referentes ao ensino secundário e aos acontecimentos internacionais. Inicialmente sustentado por subvenções estrangeiras, e mais tarde patrocinado pelo ministério da Educação, um movimento surgiu no Brasil que objetivava a produção e divulgação de materiais didáticos que incorporassem os princípios desse paradigma. Este trabalho descreve a trajetória do paradigma e do movimento reformista do ensino de Ciências, desde sua origem nos …


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 third …


Rui Barbosa And The Argument For Teaching The Natural Sciences In The Brazilian Primary School Of The Xix Century [Rui Barbosa E O Ensino De Ciências Naturais Na Escola Brasileira Do Século Xix], Karl M. Lorenz Jul 2004

Rui Barbosa And The Argument For Teaching The Natural Sciences In The Brazilian Primary School Of The Xix Century [Rui Barbosa E O Ensino De Ciências Naturais Na Escola Brasileira Do Século Xix], Karl M. Lorenz

Karl M Lorenz

The paper discusses the ideas of Rui Barbosa on the importance of teaching science in the primary schools of nineteenth-century Brazil. Barbosa was one of the great parliamentarians of his time and one of Brazil’s most vocal advocates of educational reform in the nineteenth century. In 1882 Barbosa was directed to provide a written assessment of the1878 educational reform of Minister Leonçio de Carvalho. In the document that resulted, Barbosa states his rationale for why and how the natural sciences should be taught in the primary school. This paper relates Barbosa’s ideas on science teaching and argues that he was …

Karl M Lorenz

O estudo identifica os livros didáticos de matemática utilizados no Colégio de Pedro II do Rio de Janeiro no século XIX, considerado "padrão" para seus congêneres. A partir de informações contidas nos programas de ensino adotados no Colégio de 1838 a 1900 e com auxílio da literatura especializada, foi possível identificar a autoria e o título de trinta e dois livros-texto, sendo a maioria deles escrita por autores brasileiros e um número menor escrito por autores franceses. Infere-se que houve equivalência entre os estudos de matemática do Colégio Pedro II e dos demais colégios do Rio de Janeiro e das …


O Collegio De Pedro Ii E A Modernização Do Currículo Da Escola Secundária Brasileira [The College Pedro Ii And The Modernization Of The Secondary School Curriculum In Brazil], Karl M. Lorenz Jan 2004

O Collegio De Pedro Ii E A Modernização Do Currículo Da Escola Secundária Brasileira [The College Pedro Ii And The Modernization Of The Secondary School Curriculum In Brazil], Karl M. Lorenz

Karl M Lorenz

Este trabalho examine o papel do currículo do Colégio Pedro II na modernização do ensino secundário no Brasil de 1837 a 1889. O trabalho argumenta que o Governo Imperial seguia duas linhas de ação para alcançar este objetivo. Primeiro, introduziu no Colégio modelos curriculares e conteúdos nas disciplinas parecidos a aqueles encontrados nas melhores escolas Europeias. Segundo, implementou legislação que induzia as escolas secundárias a adotar o currículo do Colégio. Visto que a constituição proibiu que o Governo Central diretamente efetuasse mudanças nas escolas provinciais, o Corte agiu indiretamente por oferecer incentivos aos formados das instituições que adotaram o currículo …


How To Get It. Diagrammatic Reasoning As A Tool Of Knowledge Development And Its Pragmatic Dimension, Michael H.G. Hoffmann Jan 2004

How To Get It. Diagrammatic Reasoning As A Tool Of Knowledge Development And Its Pragmatic Dimension, Michael H.G. Hoffmann

Michael H.G. Hoffmann

Discussions concerning belief revision, theory development, and "creativity" in philosophy and AI, reveal a growing interest in Peirce's concept of abduction. Peirce introduced abduction in an attempt to provide theoretical dignity and clarification to the difficult problem of knowledge generation. He wrote that "An Abduction is Originary in respect to being the only kind of argument which starts a new idea." These discussions, however, have led to considerable debates about the precise way in which Peirce's abduction can be used to explain knowledge generation. The crucial question is that of understanding how we can get the new elements capable of …


Learning By Developing Knowledge Networks. A Semiotic Approach Within A Dialectical Framework, Michael H.G. Hoffmann, Wolf-Michael Roth Jan 2004

Learning By Developing Knowledge Networks. A Semiotic Approach Within A Dialectical Framework, Michael H.G. Hoffmann, Wolf-Michael Roth

Michael H.G. Hoffmann

A central challenge for research on how we should prepare students to manage crossing boundaries between different knowledge settings in life long learning processes is to identify those forms of knowledge that are particularly relevant here. In this paper, we develop by philosophical means the concept of a dialectical system as a general framework to describe the development of knowledge networks that mark the starting point for learning processes, and we use semiotics to discuss (a) the epistemological thesis that any cognitive access to our world of objects is mediated by signs and (b) diagrammatic reasoning and abduction as those …


The College Pedro Ii And The Modernization Of The Secondary School Curriculum In Imperial Brazil, Karl M. Lorenz Jul 2003

The College Pedro Ii And The Modernization Of The Secondary School Curriculum In Imperial Brazil, Karl M. Lorenz

Karl M Lorenz

This work examines the role of the curriculum of the College Pedro II to modernize secondary school education in Brazil from 1838 to 1889. It argues that the Imperial Government followed two lines of action in achieving this goal. First, the Court sought to make education in the College exemplary by continuously introducing curriculum models and course content similar to that found in the best schools in Europe. Second, it enacted legislation that induced schools to adopt the program of studies of the College. Because the constitution prohibited the Central Government from directly effecting change in provincial schools, the Court …


Science Education And The Imperial College Pedro Ii: 1838-1889, Karl M. Lorenz Jan 2003

Science Education And The Imperial College Pedro Ii: 1838-1889, Karl M. Lorenz

Karl M Lorenz

The chapter discusses science teaching in the secondary school in Brazil, with a focus on the College Pedro II. The imperial College was founded in 1837 as a model institution to be emulated by public and private secondary schools in the provinces. The paper presents observations and data on science education at the national level and a description of science teaching in the College during the XIX century. Attention is given to the curriculum, the textbooks adopted in the science courses, and the relationship between secondary science education and the entrance examinations to the medical, law and engineering faculties. Este …


Peirce's "Diagrammatic Reasoning" As A Solution Of The Learning Paradox, Michael H.G. Hoffmann Jan 2003

Peirce's "Diagrammatic Reasoning" As A Solution Of The Learning Paradox, Michael H.G. Hoffmann

Michael H.G. Hoffmann

How can we reach “new” levels of knowledge if “new” means that there is something “evolved” that cannot be generated simply by deduction or by induction from what has been given before. The paper’s first goal is to show that two paradigmatic attempts at solving this so-called “learning paradox,” Plato’s apriorism and Aristotle’s inductivism, form two horns of a dilemma: While the inductivist cannot justify any representation of data without assuming a priori given hypotheses, the apriorist cannot justify why a certain application of given ideas is correct without being caught in an infinite regress. The second goal is to …

Problems With Peirce's Concept Of Abduction, Michael H.G. Hoffmann Jan 1999

Problems With Peirce's Concept Of Abduction, Michael H.G. Hoffmann

Michael H.G. Hoffmann

Abductive reasoning takes place in forming "hypotheses" in order to explain "facts." Thus, the concept of abduction promises an understanding of creativity in science and learning. It raises, however, also a lot of problems. Some of them will be discussed in this paper: After analyzing the difference between induction and abduction (1), I shall discuss Peirce's claim that there is a "logic" of abduction (2). The thesis is that this claim can be understood, if we make a clear distinction between inferential elements and perceptive elements of abductive reasoning. For Peirce, the creative act of forming explanatory hypotheses and the …
