Conceptual Ecology of the Evolution Acceptance among Greek Education Students: Knowledge,religious practices and social influences

In this study, we explored some of the factors related to the acceptance of evolution theory among Greek university students training to be teachers in early childhood education, using conceptual ecology for biological evolution as a theoretical framework. We examined the acceptance of evolution theory and we also looked into the relationship between the acceptance and parents' education level, thinking dispositions and frequency of religious practice as independent variables. Students' moderate acceptance of evolution theory is positively correlated with the frequency of religious practices and thinking dispositions. Our findings indicate that studying a controversial issue such as the acceptance of evolution theory in a multivariate fashion, using conceptual ecology as a theoretical lens to interpret the findings, is informative. They also indicate the differences that exist between societies and how socio-cultural factors such as the nature of religion, as part of the conceptual ecology, influence acceptance of evolution and have an influence on evolution education.     

Intentions and beliefs in students' understanding and acceptance of biological evolution

We examined the intersection of students' understanding and acceptance of evolution and their epistemological beliefs and cognitive dispositions. Based on previous research, we hypothesized there would be a relation between understanding and acceptance. We also hypothesized that students who viewed knowledge as changing and who have a disposition toward open‐minded thinking would be more likely to accept the scientific explanation of human evolution, and that beliefs and dispositions would not be related to acceptance of a topic that is generally perceived as noncontroversial. Ninety‐three undergraduate students enrolled in a nonmajors biology class completed measures of their (a) content knowledge of evolution and photosynthesis and respiration; (b) acceptance of theories of animal evolution, human evolution, and photosynthesis; and (c) epistemological beliefs and cognitive dispositions. Although our findings did reveal a significant relation between knowledge and reported acceptance for photosynthesis, there was no relation between knowledge and acceptance of animal or human evolution. Epistemological beliefs were related to acceptance, but only to the acceptance of human evolution. There was no relation between students' epistemological beliefs and their general acceptance of animal evolution or photosynthesis. Three subscales, Ambiguous Information, Actively Open‐Minded Thinking, and Belief Identification, were significantly correlated with understanding evolutionary theory. We argue these findings underscore the importance of intentional level constructs, such as epistemological beliefs and cognitive dispositions, in the learning of potentially controversial topics. © 2003 Wiley Periodicals, Inc.

Examination of Changes in Prospective Elementary Teachers’ Epistemological Beliefs in Science and Exploration of Factors Meditating That Change

Epistemological beliefs refer to an individual’s thinking and beliefs about the nature of knowledge and knowing. The present study examined two research questions: (1) how do prospective elementary teachers’ epistemological beliefs in science change as a result of instruction specifically designed to improve their epistemological beliefs and (2) what role does the conceptual ecology for epistemological beliefs play in their development? The study was correlational with a sample of 161 prospective elementary teachers (148 female, 13 male). Self-report questionnaires tapping four dimensions of epistemological beliefs (certainty-simplicity, justification, source, attainability of truth) were given to prospective elementary teachers at two time points during an introductory science course. Results indicated that prospective elementary teachers became more sophisticated in their beliefs across all four dimensions of epistemological beliefs. It was found that one component of conceptual ecology for epistemological beliefs, thinking dispositions, was related to the development of epistemological beliefs. Prospective teachers with high thinking dispositions developed more sophisticated beliefs in comparison to prospective teachers with low thinking dispositions.     

How strongly does statistical reasoning influence knowledge and acceptance of evolution?

A large body of research has examined students' conceptions of evolution and their relationships to acceptance of evolution. Proficiency in statistical and probabilistic reasoning has long been considered to be an essential feature of evolutionary reasoning, yet almost no empirical work has explored these putative connections. The RaPro instruments have recently been developed to measure statistical reasoning in the contexts of mathematics (RaProMath) and evolution (RaProEvo). Our study provides additional validation of these instruments using Rasch analysis and quantifies the contribution of statistical reasoning to both understanding and accepting evolution. We recruited a large sample (N = 564) of undergraduate students enrolled in an introductory biology course at a large public research university in the United States. Students completed a suite of published instruments that assessed statistical reasoning, evolutionary understanding, and evolutionary acceptance. Our findings indicate that validity inferences derived from RaPro scores generalized to the new sample, and that proficiency in statistical reasoning explained 28% of the variance in evolutionary knowledge and 19% of the variation in evolutionary acceptance. The inclusion of demographic variables into the model significantly increased the explained variance in acceptance. Notably, the variance in evolution acceptance explained by statistical reasoning was comparable to that of thinking dispositions or evolutionary knowledge reported in the literature. This work provides the first large-scale evidence of the role of statistical reasoning in evolutionary knowledge and acceptance and motivates future work to explore how statistical literacy should be integrated into evolution education efforts.     

Current Themes and Future Directions in Epistemological Research: A Commentary

This article summarizes and comments upon recent research on epistemological beliefs (i.e., beliefs about knowledge and knowing). I identify four emergent themes, outline directions for future research, and draw links between current theory and educational practice. The four themes pertain to the number relationship among, development, and measurement of epistemological beliefs. I address conceptual and methodological issues in future research. I also identify four educational implications: understanding teachers' beliefs, understanding students' beliefs, promoting critical thinking, and attempting to change teachers' and students' beliefs.     

Role of anomalous data and epistemological beliefs in middle school students’ theory change about two controversial topics

The question of theory change is crucial in knowledge construction, particularly in the process of conceptual change. This study was designed to investigate two factors that, in addition to initial theory preference, may play a crucial role in the process of theory change, that is, students’ interpretation of anomalous data on two controversial topics (the dinosaur extinction and the construction of the Giza pyramids in Egypt) and their epistemological beliefs about the nature of knowledge. Canonical correlation analyses suggested for both topics an association, stronger for the dinosaur extinction topic, between (a) acceptance of anomalous data (rated both as valid and inconsistent with the held theory), initial theory preference, epistemological belief in Certain Knowledge and (b) theory change. Data obtained from structure coefficients in canonical correlation analyses indicate that acceptance of anomalous data significantly contributed the most to theory change whereas the epistemological belief contributed the least. Finally, educational implications are drawn.     

College students' perceptions of the theory of evolution

Although a well‐corroborated scientific theory, the theory of evolution has continued to cause dilemmas for some individuals who have not easily been able to accommodate the concepts of this theory within their “cognitive culture.” The reason lies in the overlap of some ideas that the theory advocates with other social, epistemological, and religious beliefs. This study describes how 11 college biology students who completed a course on the theory of evolution perceive the relationship among their epistemological beliefs about science, their beliefs about religion, and their perception of nature and causality and their position regarding the theory of evolution. It also compares the different positions of the students to that of the course instructor. Questionnaires and semistructured interviews were used to collect data. Qualitative methods were used to analyze the data and identify the various positions of the students and course instructor. The students' positions ranged from complete acceptance to complete rejection of the theory of evolution. The results suggest that students' personal beliefs should not be dismissed or underestimated when teaching the theory of evolution. © 2008 Wiley Periodicals, Inc.

Personal epistemology and relational pedagogy in early childhood teacher education programs

Over the last decade, research related to personal epistemological beliefs has offered insight into how to promote effective teaching and learning across educational settings. Personal epistemological beliefs reflect an individual's views about what knowledge is, how knowledge is gained, and the degree of certainty with which knowledge can be held. However, there has been no research that specifically investigates the relationship between such epistemological beliefs and early childhood practice. This paper draws together current research findings on epistemological beliefs and tertiary learning to provide a conceptual framework which can be used in early childhood teacher education programs to provide a basis for investigating early childhood teachers' understanding about their own learning and how they use this knowledge in their practice.     

Diversity of Students' Beliefs about Biological Evolution

The purpose of this study was to determine the beliefs about biological evolution held by college freshman students in one Catholic university in the Philippines. After 4 weeks of constructivist-inspired instruction, interviews and journal entries revealed that the students have diverse beliefs about the theory of evolution. They posited rejection, acceptance or doubt about the evolutionary theory based on their scientific and theological beliefs, perceptions about the evidence of evolution and misconceptions about evolutionary theory, in particular, human evolution. Based on the results, it is discerned that there indeed is a clear interaction between science and religion in the teaching and learning of science. The authors also conclude that students' current worldviews, in the form of attitudes and beliefs, affect how they understand concepts.     

Prediction of School Enrolment of Children with Intellectual Disabilities in Kenya: The role of parents' expectations,beliefs, and education

The purpose of this study was to develop a logistic regression model for the prediction of school enrolment of Kenyan children with intellectual disabilities. The initial set of predictors included three demographic variables (child's gender, child's level of intellectual disability, and parents' level of education) and six factors of parents' expectations and beliefs about future outcomes and education of children with intellectual disabilities. Previous research implicated some of these concepts in school enrolment of children with disabilities in African countries without providing a particular prediction model. The hypothesised factor structure of the instrument developed in this study was tested by using a confirmatory maximum likelihood factor analysis. A stepwise logistic regression was conducted with the initial model including all nine predictors of school enrolment of children with intellectual disabilities in Kenya. Significant predictors in the final logistic regression model were (a) parents' expectations about social acceptance of the child, (b) parents' bias against educating children with intellectual disabilities, (c) parents' beliefs about a segregated school option, (d) parents' beliefs about the appropriateness of the child's school education, and (e) parents' level of education.     

Getting to Darwin: Obstacles to Accepting Evolution by Natural Selection

Darwin’s theory of evolution by natural selection is central to modern biology, but is resisted by many people. This paper discusses the major psychological obstacles to accepting Darwin’s theory. Cognitive obstacles to adopting evolution by natural selection include conceptual difficulties, methodological issues, and coherence problems that derive from the intuitiveness of alternative theories. The main emotional obstacles to accepting evolution are its apparent conflict with valued beliefs about God, souls, and morality. We draw on the philosophy of science and on a psychological theory of cognitive and emotional belief revision to make suggestions about what can be done to improve acceptance of Darwinian ideas.     

Evolutionary biology today

“For a biologist”, wrote Sir Peter Medawar, “the alternative to thinking in evolutionary terms is not to think at all”. Yet, at the end of an education in biology in most Indian universities, this is not quite the view of evolutionary biology that one is left with. Evolution is presented summarily, almost as a footnote, rather than as a vital branch of biology providing the conceptual foundation for our modern views about the living world. In this issue ofResonance, we remember Stephen Jay Gould, who wrote extensively and eloquently about evolution for a general audience. It seems fitting, then, to also briefly discuss why evolutionary biology is important, not only conceptually but also in terms of practical applications. In this first part of a series of articles on modern evolutionary biology, we examine why the idea of evolution is so important in our intellectual history, and also take a look at the domain of evolutionary biology as a discipline. Amitabh Joshi studies and teaches evolutionary genetics and population ecology at the Jawaharlal Nehru Centre for Advanced Scientific Research, Bangalore. His current research interests are in life-history, evolution, the evolutionary genetics of biological clocks, the evolution of ecological specialization dynamics. He also enjoys music (especially traditional qawali in Braj, Farsi, Punjabi and Urdu), history, philosophy, and reading and writing poetry in Urdu, Hindi and English.     

Evolution in the Caribbean Classroom: A critical analysis of the role of biology teachers and science standards in shaping evolution instruction in Belize

A survey of the literature on evolution instruction provides evidence that teachers’ personal views and understandings can shape instructional approaches and content delivered in science classrooms regardless of established science standards. This study is the first to quantify evolutionary worldviews of in-service teachers in the Caribbean, specifically in Belize, an English-speaking nation with a high school system guided by a regional biology syllabus and strict standardized tests. Using the Measure of Acceptance of the Theory of Evolution (MATE) instrument and knowledge test, we investigated (1) the current level of acceptance and understanding of evolution as given by 97% of high school biology teachers in Belize; (2) the factors associated with acceptance and understanding of evolutionary theory. With an average MATE score of 64.4 and a mean knowledge score of 47.9%, Belizean teachers were classified as having both ‘Low Acceptance’ and ‘Low Understanding’ of evolutionary theory. A positive correlation was found between teacher acceptance and understanding of evolution. A review of the Caribbean Secondary Examination Certificate biology syllabus suggests that evolution plays a minimal role in the high school biology classroom. We believe that Belize presents a unique opening for future training on evolution instruction since 57% of the biology teachers self-proclaim to be unprepared to teach evolution. The results of this study have implications for policy, practice and research with teachers’ acceptance, understanding and confidence in teaching evolution serving as important predictors for instructional approaches used in the biology classroom.     

Finding the optimal scaffoldings for learners’ epistemological beliefs during ill-structured problem solving

This study investigates how scaffolding type and learners’ epistemological beliefs influence ill-structured problem solving. The independent variables in this study include the type of scaffolding (task-supported, self-monitoring) and the student's epistemological belief level (more advanced, less advanced). The dependent variables include three components of problem-solving skill (problem representation, solution development, monitoring and evaluation). The two-way multivariate analysis of variance results reveal that students in the self-monitoring scaffolding group earned higher scores on problem representation and solution development than those in the task-supported scaffolding group. Students with more advanced epistemological beliefs also earned higher scores on solution development and monitoring and evaluation than did those with less advanced epistemological beliefs. In addition, a significant interaction was found between scaffolding type and epistemological belief level. These findings suggest that students can benefit from self-monitoring scaffolding in web-based problem solving and that different types of scaffolding should be provided according to the student's epistemological belief level.     

Integrative assessment of Evolutionary theory acceptance and knowledge levels of Biology undergraduate students from a Brazilian university

The integrative role that Evolutionary theory plays within Biology is recognised by most scientific authors, as well as in governmental education policies, including Brazilian policies. However, teaching and learning evolution seems problematic in many countries, and Brazil is among those. Many factors may affect teachers’ and students’ perceptions towards evolution, and studies can help to reveal those factors. We used a conceptual questionnaire, the Measure of Acceptance of the Theory of Evolution (MATE) instrument, and a Knowledge test to assess (1) the level of acceptance and understanding of 23 undergraduate Biology students nearing the end of their course, (2) other factors that could affect these levels, including course structure, and (3) the most difficult topics regarding evolutionary biology. The results of this study showed that the students, on average, had a ‘Very High Acceptance’ (89.91) and a ‘Very Low Knowledge’ (59.42%) of Evolutionary theory, and also indicated a moderate positive correlation between the two (r?=?0.66, p?=?.001). The most difficult topics were related to the definition of evolution and dating techniques. We believe that the present study provides evidence for policymakers to reformulate current school and university curricula in order to improve the teachers’ acceptance and understanding of evolution and other biological concepts, consequently, helping students reduce their misconceptions related to evolutionary biology.     

Approaching and avoiding arguments: The role of epistemological beliefs, need for cognition, and extraverted personality traits

Because argumentation may promote deeper processing of content, this study examined factors affecting students’ dispositions to engage in argument, specifically epistemological beliefs, need for cognition, and extraversion (assertiveness and warmth). An instrument developed by [Infante and Rancer, 1982] was used to measure dispositions to approach or avoid arguments. Subjects were 238 undergraduates who completed surveys of the relevant constructs. Contrary to expectation that epistemological beliefs would predict the approach component by affecting the perceived usefulness of argumentation, regression analysis indicated that epistemological beliefs instead predicted the avoidance component (as did a desire to maintain warm relationships). Need for cognition predicted the approach component, whereas assertiveness predicted both. The need to better understand why some students avoid arguments is discussed.     

Practicing Critical Thinking in an Educational Psychology Classroom: Reflections from a Cultural-Historical Perspective

Present standards include creative and critical thinking among dispositions essential for the teaching profession. While teaching introductory courses in educational psychology, I have noticed that even though students can easily describe critical thinking in the abstract, they rarely and reluctantly engage in thinking critically about their own educational experiences. Emphasis on assessment of critical thinking dispositions and skills requires students to demonstrate “the right way to think.” This emphasis, I argue, decreases students' inclination to practice critical inquiry and to feel this experience as intrinsically rewarding. Exploration of socio-cultural contexts of my own and my students' upbringing helps understand how such contexts condition the critical thinking practice. I offer the cultural-historical theory of Lev Vygotsky as an alternative frame of reference that will help students practice critical thinking in an educational psychology classroom.     

Effects of an Educational Experience Incorporating an Inventory of Factors Potentially Influencing Student Acceptance of Biological Evolution

This investigation provides an extensive review of scientific, religious, and otherwise non-scientific factors that may influence student acceptance of biological evolution. We also measure the extent to which students' levels of acceptance changed following an educational experience designed to address an inclusive inventory of factors identified as potentially affecting student acceptance of evolution (n = 81, pre-test/post-test) n = 37, one-year longitudinal). Acceptance of evolution was measured using the Measure of Acceptance of the Theory of Evolution (MATE) instrument among participants enrolled in a secondary-level academic programme during the summer prior to their final year of high school and as they transitioned to the post-secondary level. Student acceptance of evolution was measured to be significantly higher than initial levels both immediately following and over one year after the educational experience. Results reported herein carry implications for future quantitative and qualitative research as well as for cross-disciplinary instruction plans related to evolutionary science and non-scientific factors which may influence student understanding of evolution.     

Scientific views and religious beliefs of college students: The case of biological evolution

The purpose of this study was to explore how some university biology majors in Beirut, Lebanon, accommodate the theory of biological evolution with their existing religious beliefs. Sixty-two students enrolled in a required senior biology seminar responded to open-ended questions that addressed (a) their understanding of the theory of evolution, (b) their perception of conflict between this theory and religion, and (c) whether the theory of evolution clashed with their own beliefs about the world. Based on their responses, 15 students were selected for an in-depth exploration of their written responses. Students' answers clustered under 1 of 4 main positions: for evolution, against evolution, compromise, and neutral. The authors suggest that teaching students about the nature of scientific facts, theories, and evidence is more likely to enhance understanding of evolutionary theory if students are given the opportunity to discuss their values and beliefs in relation to scientific knowledge. © 1997 John Wiley & Sons, Inc.
