Scientific Conceptions (scientific + conception)
Selected AbstractsPutting the Image Back in ImaginationPHILOSOPHY AND PHENOMENOLOGICAL RESEARCH, Issue 1 2001AMY KIND Despite their intuitive appeal and a long philosophical history, imagery-based accounts of the imagination have fallen into disfavor in contemporary discussions. the philosophical pressure to reject such accounts seems to derive from two distinct sources. First, the fact that mental images have proved difficult to accommodate within a scientific conception of mind has led to numerous attempts to explain away their existence, and this in turn has led to attempts to explain the phenomenon of imagining without reference to such ontologically dubious entities as mental images. Second, even those philosophers who accept mental images in their ontology have worried about what seem to be fairly obvious examples of imaginings that occur without imagery. In this paper, I aim to relieve both these points of philosophical pressure and, in the process, develop a new imagery-based account of the imagination: the imagery model. [source] Cognitive perturbation through dynamic modelling: a pedagogical approach to conceptual change in scienceJOURNAL OF COMPUTER ASSISTED LEARNING, Issue 6 2006S. C. Li Abstract While simulations have widely been used to facilitate conceptual change in learning science, results indicate that significant disparity or gap between students' prior conceptions and scientific conceptions still exists. To bridge the gap, we argue that the applications of computer simulation in science education should be broadened to enable students to model their thoughts and to improve and advance their theories progressively. While computer simulations are often used to offer opportunities for students to explore scientific models, they do not give them the space to explore their own conceptions, and thus cannot effectively address the challenge of changing students' alternative conceptions. Findings from our recent empirical study reveal that, firstly, dynamic modelling using the environment WorldMaker 2000 in conjunction with the use of a cognitive perturbation strategy by the teacher was effective in helping students to migrate from their alternative conceptions towards a more scientifically inclined one; secondly, the pathways of conceptual change across groups were idiosyncratic and diverse. Respecting students' ideas seriously and providing cognitive perturbation at appropriate junctures of the inquiry process are found to be conducive to fostering conceptual change. In this paper, we will report on the details of the pedagogical approach adopted by the teacher and portray how students' conceptions change during the entire process of model building. [source] The use of a computer simulation to promote scientific conceptions of moon phasesJOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 3 2008Randy L. Bell Abstract This study described the conceptual understandings of 50 early childhood (Pre-K-3) preservice teachers about standards-based lunar concepts before and after inquiry-based instruction utilizing educational technology. The instructional intervention integrated the planetarium software Starry Night BackyardŌ with instruction on moon phases from Physics by Inquiry by McDermott (1996). Data sources included drawings, interviews, and a lunar shapes card sort. Videotapes of participants' interviews were used along with the drawings and card sorting responses during data analysis. The various data were analyzed via a constant comparative method in order to produce profiles of each participant's pre- and postinstruction conceptual understandings of moon phases. Results indicated that before instruction none of the participants understood the cause of moon phases, and none were able to draw both scientific moon shapes and sequences. After the instruction with technology integration, most participants (82%) held a scientific understanding of the cause of moon phases and were able to draw scientific shapes and sequences (80%). The results of this study demonstrate that a well-designed computer simulation used within a conceptual change model of instruction can be very effective in promoting scientific understandings. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 45: 346,372, 2008 [source] Teaching & Learning Guide for: Can a Darwinian Be a Christian?RELIGION COMPASS (ELECTRONIC), Issue 3 2008Gregory W. Dawes Author's Introduction The article was provoked by recent discussion of the so-called ,conflict thesis': the idea that the Christian faith and the findings of modern science are necessarily at odds. This thesis is generally attributed to John William Draper (1811,1882) and Andrew Dickson White (1832,1918). Recent opposition to their work dates from a 1979 publication by James Moore. Moore argues that the warfare metaphor employed by Draper and White misrepresents the historical reality, by suggesting that the religion and science debates were clashes between distinct groups of people who were sharply polarized and violently antagonistic. Since then, similar criticisms have been made by historians, such as David Livingstone, Ronald Numbers, and David Lindberg. A key question here is: what does the conflict thesis entail? If it holds that Christian thinkers have invariably opposed scientific progress, while the defenders of science have been non-believers, it would be demonstrably false. But there exist more interesting forms of conflict thesis, which are philosophical rather than historical. These suggest that there is some tension between what Christians have traditionally believed and the findings of modern science, particularly Darwin's theory of evolution by natural selection. Even if the two are not, strictly speaking, incompatible, the truth of one may constitute evidence against the truth of the other. Darwin's theory also undercuts traditional arguments from design, and highlights the epistemological divide between religious and scientific conceptions of authority. Online Materials The following sites contain audio and video files, as well as text and images. 1. http://www.meta-library.net/history/intro-frame.html This is a useful overview of the historical debate by Ronald Numbers, with links to other sites. Most presenters follow Moore in opposing the conflict thesis, narrowly defined, but neglect the conflicts that my article highlights. 2. http://www.pbs.org/wgbh/nova/id/program.html Here one can view an excellent, 2-h PBS television documentary on the Dover, Pennsylvania trial in December 2005 regarding the teaching of ,intelligent design' (ID) in public schools. 3. http://www.butler.edu/clergyproject/rel_evol_sun.htm This is a letter signed by more than 11,000 clergy, arguing that there is no conflict between religion and science, and encouraging (among other things) the liturgical celebration of evolution by natural selection. 4. http://www.discovery.org/csc/ At the other end of the theological spectrum, this is the website of the Discovery Institute, devoted to opposing Darwinism and promoting ,intelligent design' (ID). Controversially, it presents ID as a scientific theory, rather than a religious doctrine. 5. http://www.asa3.org/ Somewhere between the Clergy Letter Project and the Discovery Institute lies the American Scientific Affiliation (ASA). The ASA ,does not take a position when there is honest disagreement between Christians', so it embraces a variety of perspectives. Sample Syllabus The following could form the basis for a graduate seminar on religion and science, focusing on the Darwinian controversies. One could, for instance, devote two classes to each of these topics. 1. The Draper-White Thesis I recommend reading extracts from the two writers thought to be responsible for the conflict thesis, to establish what each actually said. John William Draper, The History of the Conflict between Religion and Science, International Scientific Series 13 (London: Henry S. King & Co., 1875), chap. 8. Andrew Dickson White, A History of the Warfare of Science with Theology in Christendom (1896; New York, NY: Dover Publications, 1960), vol. 1, chap. 1. 2. Criticism of the Draper-White Thesis Either of the following readings from historians critical of Draper and White's work would be a useful starting point for discussion. James R. Moore, The Post-Darwinian Controversies: A Study of the Protestant Struggle to Come to Terms with Darwin in Great Britain and America, 1870,1900 (Cambridge: Cambridge University Press, 1979), chap. 1. David N. Livingstone, ,Re-placing Darwinism and Christianity', in David C. Lindberg and Ronald L. Numbers (eds.), When Science and Christianity Meet, pp. 183,202 (Chicago, IL: University of Chicago Press, 2003). 3. The Incompatibility Thesis Many authors attempt to show that Darwinism and Christianity and compatible. But it would be useful to examine Pope John Paul II's statement on this topic, along with some responses by biologists and philosophers. John Paul II, ,The Pope's Message on Evolution and Four Commentaries', The Quarterly Review of Biology, 72:4 (1997): 375,406. 4. The Evidential Thesis Students might enjoy reading and discussing the following article by a leading evolutionary biologist. George C. Williams, ,Mother Nature Is a Wicked Old Witch', in Matthew H. Nitecki and Doris V. Nitecki (eds.), Evolutionary Ethics, 217,31 (Albany, NY: State University of New York Press, 1993). 5. The Replacement Thesis This is an important but often neglected book. Students would benefit from reading at least the first chapter. Neal C. Gillespie, Charles Darwin and the Problem of Creation (Chicago, IL: University of Chicago Press, 1979), chap. 1. 6. The Faith and Reason Thesis The following article by a well-known historian and philosopher of science touches on some of the key issues. Ernan McMullin, ,Evolution and Special Creation', Zygon 28:3 (1993): 299,335. Focus Questions 1There exist many Christian thinkers who accept Darwin's theory of evolution by natural selection. Does that mean there is no conflict between Darwinism and Christianity? 2Taken at face value, Genesis 1,3 tells the story of the origins of the world and of human beings. What aspects of that story would you consider essential to the Christian faith? 3If we have an entirely natural explanation of the origins of complex living organisms, do we still have reasons to believe in a creator God? 4If God could have created complex living beings by a simple command, why would he choose a lengthy and wasteful process such as natural selection? 5Could a Christian regard the existence of God in the same way as a scientific hypothesis, that is to say, to be accepted only in so far as it is supported by the evidence? Seminar Activity I would suggest a debate, in which students sympathetic to the creationist position are asked to defend Darwin's theory, while students sympathetic to evolution are asked to argue against it. [source] Effectiveness of problem-based learning on academic performance in geneticsBIOCHEMISTRY AND MOLECULAR BIOLOGY EDUCATION, Issue 6 2007Gülsüm Araz Abstract This study aimed at comparing the effectiveness of problem-based learning (PBL)1 and traditional lecture-based instruction on elementary school students' academic achievement and performance skills in a science unit on genetics while controlling for their reasoning ability. For the specified purpose, twoinstructional methods were randomly assigned to intact classes of two different teachers. Each teacher had both PBL classes and traditional classes. Although students in PBL classes (n = 126) worked on ill-structured problems cooperatively with the guidance of the teacher, students in traditional classes (n = 91) received instruction based on teacher's explanations, discussions, and textbooks. Genetics Achievement Test was developed by researchers to measure the academic achievement and performance skills. Multivariate Analysis of Covariance results showed that the PBL students had higher academic achievement and performance skills scores (M = 11.44 and M = 2.67, respectively) when compared with those in traditional classes (M = 10.91 and M = 2.20, respectively). This indicated that the PBL students tend to better acquire scientific conceptions related to genetics and integrate and organize the knowledge. Moreover, it was found that the reasoning ability explained a significant portion of variance in the scores of academic achievement and performance skills. [source] | |||||||||||||
