We Teach As We Are Taught: Exploring The Potential For Emotional Climate To Enhance Elementary Science Preservice Teacher Education, Stacy Olitsky Jan 2013

We Teach As We Are Taught: Exploring The Potential For Emotional Climate To Enhance Elementary Science Preservice Teacher Education, Stacy Olitsky

Stacy Olitsky

Bellocchi, Ritchie, Tobin, Sandhu and Sandhu’s (2013) study highlights the crucial role that emotions play in learning at the university level in a preservice secondary science teacher education class. They examine the classroom structures that tended to lead to both a positive valence and a high level of intensity of the emotional climate (EC). This article explores the implications of their study for better understanding how to foster a positive classroom emotional climate for elementary level preservice teachers, given the specifics of elementary school environments. Drawing on theories of interactional solidarity. I explore the implications of EC for increasing pre-service …


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 …


Understanding Engagement In Science Education: The Psychological And The Social, Stacy Olitsky, Catherine Milne Jan 2012

Understanding Engagement In Science Education: The Psychological And The Social, Stacy Olitsky, Catherine Milne

Stacy Olitsky

Traditionally, engagement as a feature of student action has been the purview of psychologists seeking to identify the individual variables that come together to constitute student engagement. Recognition of the complexity of the concept has led to multidimensional models that include behavioral, emotional, and cognitive engagement. Data for these studies typically are culled from surveys of individual students. However, such approaches have two limitations – there is no place for examining collective engagement and the role of classroom interactions for engendering engagement is not sufficiently emphasized. In this chapter, we explore sociological approaches that can offer the possibility for developing …


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.


Coherence, Contradiction And The Development Of School Science Identities, Stacy Olitsky, Linda Loman, Jessica Gardner, Markita Billups Jan 2010

Coherence, Contradiction And The Development Of School Science Identities, Stacy Olitsky, Linda Loman, Jessica Gardner, Markita Billups

Stacy Olitsky

This ethnographic study took place in a diverse eighth grade science classroom in an urban magnet school where students demonstrate significant variation in classroom achievement and participation. In this paper, we use an activity-theoretical framework to examine classroom events in order to identify and work toward reducing contradictions that can interfere with students developing positive school science identities. We discuss several contradictions for students in this classroom, including the conflicts between social and academic goals and the inconsistencies between science and math classes. We found that in situations where students could build and use social capital through learning science, they …


“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 …

Facilitating Identity Formation, Group Membership, And Learning In Science Classrooms: What Can Be Learned From Out Of Field Teaching In An Urban School, Stacy Olitsky Jan 2007

Facilitating Identity Formation, Group Membership, And Learning In Science Classrooms: What Can Be Learned From Out Of Field Teaching In An Urban School, Stacy Olitsky

Stacy Olitsky

This paper explores both the obstacles and the possibilities for students developing identities associated with science by engaging in solidarity-building classroom interactions. Data come from ethnographic research conducted in a diverse eighth-grade urban magnet school classroom in which the teacher taught out of field for part of the year. Contrary to expectations, more students participated and reported enjoying science when the teacher was out of field. Analysis of classroom interactions indicated that while in field, the teacher primarily engaged in “front stage” performances that hid her struggles with the material and accentuated students’ views of science as an elite status …


Promoting Student Engagement In Science: Interaction Rituals And The Pursuit Of A Community Of Practice, Stacy Olitsky Jan 2007

Promoting Student Engagement In Science: Interaction Rituals And The Pursuit Of A Community Of Practice, Stacy Olitsky

Stacy Olitsky

This study explores the relationship between interaction rituals, student engagement with science, and learning environments modeled on communities of practice based on an ethnographic study of an eighth grade urban magnet school classroom. It compares three interactional events in order to examine the classroom conditions and teacher practices that can foster successful interaction rituals (IRs), which are characterized by high levels of emotional energy, feelings of group membership, and sustained interest in the subject. Classroom conditions surrounding the emergence of successful IRs included mutual focus, familiar symbols and activity structures, the permissibility of some side-talk, and opportunities for physical and …


Identity, Interaction Ritual, And Students' Strategic Use Of Science Language, Stacy Olitsky Jan 2007

Identity, Interaction Ritual, And Students' Strategic Use Of Science Language, Stacy Olitsky

Stacy Olitsky

An important part of learning science is formulating ideas, debating explanations, and talking about science with others. Yet students may still avoid “talking science” in class even if they are familiar with the content knowledge. Drawing on data from an ethnographic study of an eighth-grade urban science classroom, I argue that students’ expressions of knowledge in science class can be considered a strategic move, or a choice, aimed at supporting identity claims and increasing the likelihood of engaging in successful interaction rituals characterized by entrainment and solidarity. The results of this study suggest that a student’s knowledge of the subject …


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 …


Corpus Data And The Teaching And Learning Of Science In English In Malaysian Primary And Secondary Schools, Arshad Abd Samad Jan 2005

Corpus Data And The Teaching And Learning Of Science In English In Malaysian Primary And Secondary Schools, Arshad Abd Samad

Arshad Abd Samad

The post independence Malaysian school system has gone through several curricular revisions not only in terms of content and subject matter but also in the medium of instruction used. In 1980, the national language, Malay, was adopted as the medium of instruction in schools in place of the English language. After more than twenty years of instruction in the national language, the medium of instruction for Science based subjects at the first year of primary and secondary schools in Malaysia has recently reverted to the English language. This has largely been due to increasing concern over perceived falling standards of …


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 …


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 …


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 …

Latino Performance In Rural Public Schools: Grades 3,6,12, Refugio Rochin, Steve Hampton, Javier Ekboir Jan 1995

Latino Performance In Rural Public Schools: Grades 3,6,12, Refugio Rochin, Steve Hampton, Javier Ekboir

Refugio I. Rochin

Using multiple regression analysis, we compare non-Latino vs Latino test scores in rural school districts (grades 3,6,12) to determine the "effects" of Latino concentration, English proficiency, socio-economic status and school funding. We find relatively better test results for Latinos as Latino concentration increases. We provide theoretical hypothesis for more study.
