Grist to the Mill of Anti-evolutionism: The Failed Strategy of Ruling the Supernatural Out of Science by Philosophical Fiat

According to a widespread philosophical opinion, science is strictly limited to investigating natural causes and putting forth natural explanations. Lacking the tools to evaluate supernatural claims, science must remain studiously neutral on questions of metaphysics. This (self-imposed) stricture, which goes under the name of ??methodological naturalism??, allows science to be divorced from metaphysical naturalism or atheism, which many people tend to associate with it. However, ruling the supernatural out of science by fiat is not only philosophically untenable, it actually provides grist to the mill of anti-evolutionism. The philosophical flaws in this conception of methodological naturalism have been gratefully exploited by advocates of intelligent design creationism to bolster their false accusations of naturalistic bias and dogmatism on the part of modern science. We argue that it promotes a misleading view of the scientific endeavor and is at odds with the foremost arguments for evolution by natural selection. Reconciling science and religion on the basis of such methodological strictures is therefore misguided.     

Can Science Test Supernatural Worldviews?

Several prominent scientists, philosophers, and scientific institutions have argued that science cannot test supernatural worldviews on the grounds that (1) science presupposes a naturalistic worldview (Naturalism) or that (2) claims involving supernatural phenomena are inherently beyond the scope of scientific investigation. The present paper argues that these assumptions are questionable and that indeed science can test supernatural claims. While scientific evidence may ultimately support a naturalistic worldview, science does not presuppose Naturalism as an a priori commitment, and supernatural claims are amenable to scientific evaluation. This conclusion challenges the rationale behind a recent judicial ruling in the United States concerning the teaching of “Intelligent Design” in public schools as an alternative to evolution and the official statements of two major scientific institutions that exert a substantial influence on science educational policies in the United States. Given that science does have implications concerning the probable truth of supernatural worldviews, claims should not be excluded a priori from science education simply because they might be characterized as supernatural, paranormal, or religious. Rather, claims should be excluded from science education when the evidence does not support them, regardless of whether they are designated as ‘natural’ or ‘supernatural’.     

Methodological individualism,educational administration,and leadership

There are two major categories of explanation for organisational performance: structural and individual. With the shift away from systems-theoretic accounts that occurred in the 1980s, structural explanations have been replaced increasingly by the individualism of leadership and leader-centric explanations, especially when it comes to schools. In this paper, we argue that leader-centric accounts involve a commitment to methodological individualism and that there are four serious problems with this view. First, it is logically difficult to describe individual actions without recourse to structures. Second, methodological individualism fosters a centralised mindset inviting the attribution of leadership where none may exist. Third, evidence for distributed cognition compromises leader-centrism. And fourth, administrative tasks themselves are often highly structured. In response to these problems, we urge a more balanced approach to organisational functioning, one that involves both structures and individuals.     

Discourse Generation for Instructional Applications: Identifying and Exploiting Relevant Prior Explanations

To reap the benefits of natural language interaction, tutorial systems must be endowed with the properties that make human natural-language interaction so effective. One striking feature of naturally occurring interactions is that human tutors and students freely refer to the context created by prior explanations. In contrast, computer-generated utterances that do not draw on the previous discourse often seem awkward and unnatural and may even be incoherent. The explanations produced by such systems are frustrating to students because they repeat the same information over and over again. Perhaps more critical is that, by not referring to prior explanations, computer-based tutors are not pointing out similarities between problem-solving situations and therefore may be missing out on opportunities to help students form generalizations. In this article, we discuss several observations from an analysis of human-human tutorial interactions and provide examples of the ways in which tutors and students refer to previous explanations. We describe how we have used a case-based reasoning algorithm to enable a computational system to identify prior explanations that may be relevant to the explanation currently being generated. We then describe two computational systems that can exploit this knowledge about relevant prior explanations in constructing their subsequent explanations.     

Students’ model-based explanations about natural selection and antibiotic resistance through socio-scientific issues-based learning

Antibiotic resistance (ABR) is a significant contemporary socio-scientific issue. To engage in informed reasoning about ABR, students need to understand natural selection. A secondary science unit was designed and implemented, combining an issues-based approach and model-based reasoning, to teach students about natural selection and ABR. This sequential explanatory mixed methods study explored students’ explanations of natural selection. Students created model-based explanations (MBEs) about ABR and verbally explained generalised natural selection during semi-structured interviews. Students’ MBEs significantly increased in natural selection content, and misconceptions about natural selection and ABR significantly decreased after the unit. However, students’ explanations of generalised natural selection differed from ABR explanations. Students struggled to include mutation as the cause of initial variation when explaining generalised natural selection, whereas students included mutation when explaining ABR but often did so after selection pressure. Qualitative analysis indicated students correctly explained ABR or correctly explained generalised natural selection, but none correctly explained both. Students who did understand ABR struggled to apply their understanding to a context other than ABR. This study demonstrates contextual differences in students’ natural selection ideas and provides implications for natural selection instruction. While ABR is a compelling issue to contextualise natural selection instruction, it may be problematic.     

An Exploration of Indigenous Knowledge Related to Physics Concepts Held by Senior Citizens in Chókwé, Mozambique

Indigenous knowledge is at risk of being lost in many parts of the world. It is important to find ways to preserve it for both cultural and practical reasons, since it is often well-suited to addressing local needs using available resources. If indigenous knowledge can be incorporated into school science curricula, it can also provide familiar contexts within which to learn scientific concepts, as well as helping the younger generation to recognise its value. The purpose of this study was to identify indigenous knowledge that could be related to physics concepts, with a view to integrating it into school curricula. Twenty-nine senior citizens from Chókwé, a rural village in Mozambique, volunteered to participate in two sets of in-depth interviews. The first set of interviews was individual and unstructured in order to explore which aspects of indigenous knowledge might be related to physics concepts. The second set was semi-structured and conducted in small groups in order to probe participants’ understanding and application of the identified physics concepts. The results showed that participants had indigenous knowledge that was useful to them in their daily lives and that were applications of thermal physics, static electricity and mechanics concepts. In some cases participants’ explanations were aligned to physics explanations, in some cases they were similar to students’ alternative conceptions identified in the literature, and in other cases they referred to supernatural phenomena.

A conceptual guide to natural history museum visitors' understanding of evolution

Museum visitors are an ideal population for assessing the persistence of the conceptual barriers that make it difficult to grasp Darwinian evolutionary theory. In comparison with other members of the public, they are more likely to be interested in natural history, have higher education levels, and be exposed to the relevant content. If museum visitors do not grasp evolutionary principles, it seems unlikely that other members of the general public would do so. In the current study, 32 systematically selected visitors to three Midwest museums of natural history provided detailed open‐ended explanations of biological change in seven diverse organisms. They were not told that these were evolutionary problems. Responses were coded as: informed naturalistic reasoning, featuring some understanding of key evolutionary concepts, novice naturalistic reasoning, featuring intuitive explanations that are also present in childhood, and creationist reasoning, featuring supernatural explanations. All visitors were mixed reasoners, using one or more of these patterns in different permutations across the seven organisms: 72% used a combination of informed naturalistic reasoning and novice naturalistic reasoning, while a further 28% added creationist reasoning to this mix. Correlational analyses indicated that for many visitors these reasoning patterns were coherent rather than fragmented. The theoretical model presented in this article contributes to an analysis of the developmental and cultural factors associated with these patterns. This could help educators working in diverse educational settings understand how to move visitors and students toward more informed reasoning patterns. © 2009 Wiley Periodicals, Inc.

论《耳食录》志怪幻想的创新特征

纵观志怪小说发展的历程,有一条由物到人、不断人格化的轨迹,《耳食录》中则出现了与此方向相反的拟物化模式。以往的志怪幻想大都具有外向性特征,《耳食录》则表现出内向性特征。这些变化在志怪幻想自身的嬗变过程中具有创新价值,它触及和影响了志怪幻想的基本模式和框架,体现了志怪想像在某一方向上的转折。正因为如此,我们不能把《耳食录》当作一般的志怪仿作看待。     

Understanding randomness and its impact on student learning: lessons learned from building the Biology Concept Inventory (BCI)

While researching student assumptions for the development of the Biology Concept Inventory (BCI; http://bioliteracy.net), we found that a wide class of student difficulties in molecular and evolutionary biology appears to be based on deep-seated, and often unaddressed, misconceptions about random processes. Data were based on more than 500 open-ended (primarily) college student responses, submitted online and analyzed through our Ed's Tools system, together with 28 thematic and think-aloud interviews with students, and the responses of students in introductory and advanced courses to questions on the BCI. Students believe that random processes are inefficient, whereas biological systems are very efficient. They are therefore quick to propose their own rational explanations for various processes, from diffusion to evolution. These rational explanations almost always make recourse to a driver, e.g., natural selection in evolution or concentration gradients in molecular biology, with the process taking place only when the driver is present, and ceasing when the driver is absent. For example, most students believe that diffusion only takes place when there is a concentration gradient, and that the mutational processes that change organisms occur only in response to natural selection pressures. An understanding that random processes take place all the time and can give rise to complex and often counterintuitive behaviors is almost totally absent. Even students who have had advanced or college physics, and can discuss diffusion correctly in that context, cannot make the transfer to biological processes, and passing through multiple conventional biology courses appears to have little effect on their underlying beliefs.     

Young children’s impressionable use of teleology: the influence of question wording and questioned topic on teleological explanations for natural phenomena

There is a significant body of research on children’s preconceptions concerning scientific concepts and the impact this has upon their science education. One active issue concerns the extent to which young children’s explanations for the existence of natural kinds rely on a teleological rationale: for example, rain is for watering the grass, or tigers’ stripes are for camouflage. It has been argued that this teleological tendency hampers children’s ability to learn about causality in the natural world. This paper investigates two factors (question wording and topic) which it is argued have led to a misestimation of children’s teleological tendencies within the area natural phenomena: i.e. those that are time-constrained, natural events or process such as snow, clouds or night. Sixty-six (5–8 years old) children took part in a repeated-measures experiment, answering both open and leading questions across 10 topics of natural phenomena. The findings indicate that children’s teleological reasoning may have been overestimated as open-question forms significantly reduced their tendency to answer teleologically. Moreover, the concept of teleology is more nuanced than often suggested. Consequently, young children may be more able to learn about causal explanations for the existence of natural phenomena than the literature implies.

Children’s Ability to Learn Evolutionary Explanations for Biological Adaptation

Research Findings: Evolution by natural selection is often relegated to the high school curriculum on the assumption that younger students cannot grasp its complexity. We sought to test that assumption by teaching children ages 4–12 (n = 96) a selection-based explanation for biological adaptation and comparing their success to that of adults (n = 30). Participants provided explanations before and after a 10-min, analogy-based tutorial illustrating the principles of variation, differential survival, differential reproduction, inheritance, and population change. Although younger children (ages 4–6) showed minimal evidence of learning these principles, older children (ages 7–12) showed robust evidence of doing so, learning them at rates equivalent to adults. Participants of all ages, however, provided nonevolutionary explanations for biological adaptations (i.e., explanations referencing need, growth, and creation) nearly as often at posttest as they did at pretest. Practice or Policy: These results suggest that older elementary school-age children can be taught evolutionary concepts but that learning such concepts does not lead to the automatic replacement of nonevolutionary views of biological adaptation, which must be addressed separately.     

Village Elders’ and Secondary School Students’ Explanations of Natural Phenomena in Papua New Guinea

This research investigated the sources of explanations and understanding of natural phenomena in terms of the students’ cultural and school science experiences. The first phase involved interviews with eight village elders that probed their explanations and understanding of natural phenomena. The second phase involved the design, development and administration of two questionnaires on natural phenomena to 179 students in a rural boarding high school in Papua New Guinea (PNG). Most village elders gave explanations of many of the phenomena in terms of spirits, spells, magic, religion, and personal experiences. Most school-aged students choose scientific explanations of natural phenomena in terms of what they had learned in school or from personal experiences. However, many choose explanations of the same phenomena about spirits, spells and magic that came from the village, family or home. The study revealed that students’ ideas about natural phenomena are strongly governed and controlled by their school science knowledge in the school setting. It is likely that their own traditional knowledge cannot be identified in a school setting but that questionnaires in the students’ local language be given to students in their villages (as opposed to school). In addition, so as not to diminish the value of this traditional knowledge, science education programs are needed that are able to consider and harmonise traditional knowledge with school science.

Generating multiple solutions for a problem: A comparison of the responses of U.S. and Japanese students

A task involving simple mathematics, yet complex in its call for the generation of multiple solution methods, was administered to about 150 U.S. students, most of whom were in fourth grade. Written responses were examined for correctness, evidence of strategy use and mode of explanation. Results for the U.S. sample were also compared to those obtained from about 200 Japanese fourth-grade students. Students in both countries (a) produced multiple solutions and explanations of their solutions, (b) exhibited almost identical patterns and frequency of strategy use across response occasions, and (c) used the same kinds of explanations, with a majority of the responses involving solution explanations that combined both visual and verbal/symbolic features. Nevertheless, Japanese students tended to produce explanations involving more sophisticated mathematical ideas (multiplication rather than addition) and formalisms (mathematical expressions rather than verbal explanations) than did U.S. students.     

论儒教伦理的缺陷及其与儒教天道观的关系

通过对儒教对天的崇拜的剖析，证明这个“天”是一种有抽象的绝对普遍性的自然实体，这种崇拜建立起一种普遍的道德意识，不是能为在血缘家族关系之外的社会领域建立超自然超血缘的普遍伦理，而是只能勉强建立一种不纯粹的父系血缘等级伦理，故春秋时汉民族的理智觉醒必然使其丧失真理性，战国后中国两千年的历史轮回缘由即在于此。     

Assessing the creativity of scientific explanations in elementary science: an insider–outsider view of intuitive assessment in the hypothesis space

Assessing creativity is commonly believed to be difficult but there is evidence that an intuitive, holistic assessment is easy and reliable. Given that children can engage in creative activity and teachers are expected to foster it, some assessment of it could aid planning and optimise support. Assessing creativity intuitively and holistically could be a useful, quick way of assessing to inform teaching. A teacher of young children, however, is essentially an outsider in the child’s world and often also in the world of science. Judging a child’s creativity in this way from a child’s point of view may not always be easy or reliable. Here, pre‐service elementary teachers in the UK assessed explanations of simple science events. Their holistic assessments of creativity did not agree to any great extent. Agreement improved when they assessed some of the attributes of creativity but was still less than expected. Nevertheless, these novices’ assessments as a whole showed there was some ability to discriminate usefully between explanations, albeit with considerable variation from teacher to teacher. Some implications for teacher training are described.     

Students’ intuitive explanations of the causes of homologies and adaptations

This paper reports data from a study aiming to explore secondary students’ preconceptions and explanations about evolutionary processes. Students may exhibit both alternative and scientifically acceptable conceptions and bring different ones into play in response to different problem contexts. Hence, the examination of their explanations before instruction within different problem contexts is expected to highlight the concepts that instruction should put more emphasis on. To achieve this, an open-ended questionnaire in conjunction with semi-structured interviews was used to allow students to express their own views on issues related to evolution. Students’ explanations highlighted their lack of knowledge of important evolutionary concepts such as common descent and natural selection. In addition, many students explained the origin of traits as the result of evolution through need via purposeful change or as carefully designed adaptations. Rather than evolutionary, final causes formed the basis for the majority of students’ explanations. In many cases students provided different explanations for the same process to tasks with different content. It seems that the structure and the content of the task may have an effect on the explanations that students provide. Implications for evolution education are discussed and a minimal explanatory framework for evolution is suggested.
