While mechanistic explanation and, to a lesser extent, nomological explanation are well-explored topics in the philosophy of biology, topological explanation is not. Nor is the role of diagrams in topological explanations. These explanations do not appeal to the operation of mechanisms or laws, and extant accounts of the role of diagrams in biological science explain neither why scientists might prefer diagrammatic representations of topological information to sentential equivalents nor how such representations might facilitate important processes of explanatory reasoning unavailable to (...) scientists who restrict themselves to sentential representations. Accordingly, relying upon a case study about immune system vulnerability to attacks on CD4+ T-cells, I argue that diagrams group together information in a way that avoids repetition in representing topological structure, facilitate identification of specific topological properties of those structures, and make available to controlled processing explanatorily salient counterfactual information about topological structures, all in ways that sentential counterparts of diagrams do not.

V nasledujúcom príspevku sa snažíme zdôvodniť vyčlenenie troch typov procesov v pozorovanom vesmíre - procesov slabo, stredne a silne usmernených, a to na základe rôznej miery autonómnosti ich štruktúrnych prvkov a rôznej miery či intenzity zákonov, ktorými sú usmerňované alebo riadené. Individuálne a konkrétne procesy sú tak v podstate totožné s individuálnymi a konkrétnymi systémami, cez ktoré, v ktorých a prostredníctvom ktorých sa úplne realizujú, disponujúc tak vždy a všade vlastným substanciálnym obsahom. Na tomto základe potom vyčleňujeme slabo usmernené procesy (...) v neživej prírode s málo vyčlenenými alebo autonómnymi štruktúrnymi prvkami, stredne usmernené procesy živej prírody s oveľa väčšími, vyčlenenejšími a autonómnejšími štruktúrnymi prvkami vo forme živých buniek a postupne rastúcich a zdokonaľujúcich sa organizmov a tried organizmov a nakoniec silne usmernené procesy tzv. sociálnej prírody alebo ľudskej spoločnosti, pozostávajúcej z ľudí ako svojich základných alebo štruktúrnych prvkov a tiež z nimi generovaného technického a/lebo civilizačného "obalu", ktoré sú podobne ako živé procesy a systémy usmerňované a riadené čoraz väčším počtom pre nich špecifických vedeckých zákonov, princípov alebo "pravidiel".

This inaugural handbook documents the distinctive research field that utilizes history and philosophy in investigation of theoretical, curricular and pedagogical issues in the teaching of science and mathematics. It is contributed to by 130 researchers from 30 countries; it provides a logically structured, fully referenced guide to the ways in which science and mathematics education is, informed by the history and philosophy of these disciplines, as well as by the philosophy of education more generally. The first handbook to cover the (...) field, it lays down a much-needed marker of progress to date and provides a platform for informed and coherent future analysis and research of the subject. -/- The publication comes at a time of heightened worldwide concern over the standard of science and mathematics education, attended by fierce debate over how best to reform curricula and enliven student engagement in the subjects There is a growing recognition among educators and policy makers that the learning of science must dovetail with learning about science; this handbook is uniquely positioned as a locus for the discussion. -/- The handbook features sections on pedagogical, theoretical, national, and biographical research, setting the literature of each tradition in its historical context. Each chapter engages in an assessment of the strengths and weakness of the research addressed, and suggests potentially fruitful avenues of future research. A key element of the handbook’s broader analytical framework is its identification and examination of unnoticed philosophical assumptions in science and mathematics research. It reminds readers at a crucial juncture that there has been a long and rich tradition of historical and philosophical engagements with science and mathematics teaching, and that lessons can be learnt from these engagements for the resolution of current theoretical, curricular and pedagogical questions that face teachers and administrators.

This chapter utilises scholarship in philosophy of biology and philosophy of chemistry to produce meaningful implications for biology and chemistry education. The primary purpose for studying philosophical literature is to identify different perspectives on the nature of laws and explanations within these disciplines. The goal is not to resolve ongoing debates about the nature of laws and explanations but to consider their multiple forms and purposes in ways that promote deep and practical understanding of biological and chemical knowledge in educational (...) contexts. Most studies on the nature of science in science education tend to focus on general features of scientific knowledge and underemphasise disciplinary nuances. The authors aim to contribute to science education research by focusing on the characterisations of laws and explanations in biology and chemistry in the philosophical literature and illustrating how the typical coverage of biology and chemistry textbooks does not problematise meta-perspectives on the nature of laws and explanations. The chapter concludes with suggestions for making science teaching, learning and curriculum more inclusive of the epistemological dimensions of biology and chemistry. (shrink)
