Feeling of certainty: Uncovering a missing link between knowledge and acceptance of evolution

We propose a new model of the factors influencing acceptance of evolutionary theory that highlights a novel variable unexplored in previous studies: the feeling of certainty (FOC). The model is grounded in an emerging understanding of brain function that acknowledges the contributions of intuitive cognitions in making decisions, such as whether or not to accept a particular theoretical explanation of events. Specifically, we examine the relationships among religious identity, level of education, level of knowledge, FOC, and level of evolutionary acceptance to test whether our proposed model accurately predicts hypothesized pathways. We employ widely used measures—the CINS, MATE, and ORI—in addition to new variables in multiple regression and path analyses in order to test the interrelationships among FOC and acceptance of evolutionary theory. We explore these relationships using a sample of 124 pre‐service biology teachers found to display comparable knowledge and belief levels as reported in previous studies on this topic. All of our hypothesis tests corroborated the idea that FOC plays a moderating role in relationships among evolutionary knowledge and beliefs. Educational research into acceptance of evolutionary theory will likely benefit from increased attention to non‐conscious intuitive cognitions that give rise to feeling of knowing or certainty. © 2011 Wiley Periodicals, Inc.

Exploring the factors related to acceptance of evolutionary theory among Turkish preservice biology teachers: Toward a more informative conceptual ecology for biological evolution

In this study, using multiple regression analysis, we aimed to explore the factors related to acceptance of evolutionary theory among preservice Turkish biology teachers using conceptual ecology for biological evolution as a theoretical lens. We aimed to determine the extent to which we can account for the variance in acceptance of evolutionary theory by using understanding of evolutionary theory, epistemological beliefs, thinking dispositions, and parents' educational level as independent variables. Preservice biology teachers' thinking dispositions, their understanding of evolutionary theory, and their parents' educational level are positively correlated with acceptance of evolutionary theory. We did not find any significant positive correlation between epistemological beliefs and acceptance of evolution because of low reliability coefficients of subscales of the epistemological beliefs instrument. Together they explained 10.5% of the variance. These results suggest that studying the relationship between acceptance of evolutionary theory and other related factors in a multivariate context is more informative than examining the relationship between acceptance of evolutionary theory and other factors in isolation. Our findings indicate that studying a controversial issue such as acceptance of evolutionary theory in a multivariate fashion, using conceptual ecology as a theoretical lens to interpret the findings, is informative. Our results suggest the inclusion of thinking dispositions in conceptual ecology for biological evolution. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 45: 420–443, 2008

接纳冲突:当代教师面对师生冲突

人类社会发展经历过三种冲突观:传统冲突观、人际关系冲突观和相互作用冲突观。人们对待冲突的态度也经历了因惧怕而回避冲突、接纳冲突、自觉利用冲突的正面功能三个阶段。冲突是民主社会的特征之一,冲突具有不可忽视的正面功能,接纳冲突是当代教师应具有的冲突观。在接纳冲突的基础上,教师可以利用冲突处理策略妥善解决师生冲突。     

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.     

道家生态哲学思想评析

以老庄为代表的道家思想，最闪光处是其丰富而深刻的生态哲学思想。老子提出顺应自然、天人和谐，庄子主张万物平等、物物循环。他们回答了生态哲学的基本问题，即：人与生态环境是什么关系以及如何处理好这一关系。正确认识和评价道家生态哲学思想，对于我们反思当代由西方机械自然观与人类中心论指导下创造的工业文明所引发的生态失衡、环境恶化，重新审视人类生存方式、发展模式、思维方式和价值观念，寻求人口、资源、环境和经济、社会协调持续发展，具有重要的现实意义。     

Elementary students' views of explanation,argumentation, and evidence,and their abilities to construct arguments over the school year

Science includes more than just concepts and facts, but also encompasses scientific ways of thinking and reasoning. Students' cultural and linguistic backgrounds influence the knowledge they bring to the classroom, which impacts their degree of comfort with scientific practices. Consequently, the goal of this study was to investigate 5th grade students' views of explanation, argument, and evidence across three contexts—what scientists do, what happens in science classrooms, and what happens in everyday life. The study also focused on how students' abilities to engage in one practice, argumentation, changed over the school year. Multiple data sources were analyzed: pre‐ and post‐student interviews, videotapes of classroom instruction, and student writing. The results from the beginning of the school year suggest that students' views of explanation, argument, and evidence, varied across the three contexts with students most likely to respond “I don't know” when talking about their science classroom. Students had resources to draw from both in their everyday knowledge and knowledge of scientists, but were unclear how to use those resources in their science classroom. Students' understandings of explanation, argument, and evidence for scientists and for science class changed over the course of the school year, while their everyday meanings remained more constant. This suggests that instruction can support students in developing stronger understanding of these scientific practices, while still maintaining distinct understandings for their everyday lives. Finally, the students wrote stronger scientific arguments by the end of the school year in terms of the structure of an argument, though the accuracy, appropriateness, and sufficiency of the arguments varied depending on the specific learning or assessment task. This indicates that elementary students are able to write scientific arguments, yet they need support to apply this practice to new and more complex contexts and content areas. © 2011 Wiley Periodicals, Inc.

Development of the Beliefs about Primary Education Scale: Distinguishing a developmental and transmissive dimension

In this article the development and validation of the Beliefs about Primary Education Scale (BPES) are described. The BPES is an 18-item scale for assessing primary school teachers’ beliefs toward the nature of good education, subdivided in a transmissive dimension (TD) and a developmental dimension (DD). Both dimensions assess beliefs toward the general orientation and objectives of education, the nature of the educational content, and desirable ways of knowledge acquisition. An explorative study (n=352$n=352$) revealed a two-factor structure. Both dimensions were uncorrelated, which leads to the suggestion that teachers hold layered belief systems. In a following study (n=381), construct validity of the BPES was confirmed. The BPES’ DD and TD were shown to correlate significantly with constructivist and traditional teaching beliefs.     

Assessment & Evaluation in Higher Education Using the margin of error statistic to examine the effects of aggregating student evaluations of teaching

We proposed an extended form of the Govindarajulu and Barnett margin of error (MOE) equation and used it with an analysis of variance experimental design to examine the effects of aggregating student evaluations of teaching (SET) ratings on the MOE statistic. The interpretative validity of SET ratings can be questioned when the number of students enrolled in a course is low or when the response rate is low. A possible method of improving interpretative validity is to aggregate SET ratings data from two or more courses taught by the same instructor. Based on non-parametric comparisons of the generated MOE, we found that aggregating course evaluation data from two courses reduced the MOE in most cases. However, significant improvement was only achieved when combining course evaluation data for the same instructor for the same course. Significance did not hold when combining data from different courses. We discuss the implications of our findings and provide recommendations for practice.     

Test‐based accountability: Potential benefits and pitfalls of science assessment with student diversity

Recent test‐based accountability policy in the U.S. has involved annually assessing all students in core subjects and holding schools accountable for adequate progress of all students by implementing sanctions when adequate progress is not met. Despite its potential benefits, basing educational policy on assessments developed for a student population of White, middle‐ and upper‐class, and native speakers of English opens the door for numerous pitfalls when the assessments are applied to minority populations including students of color, low SES, and learning English as a new language. There exists a paradox; while minority students are a primary intended beneficiary of the test‐based accountability policy, the assessments used in the policy have been shown to have many shortcomings when applied to these students. This article weighs the benefits and pitfalls that test‐based accountability brings for minority students. Resolutions to the pitfalls are discussed, and areas for future research are recommended. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 47: 6–24, 2010     

The Classroom Systems Observation Scale: Development of an instrument to assess classrooms using a systems perspective

This study describes the development of the Classroom Systems Observation Scale (CSOS) (Fish & Dane, 1992) and reports initial reliability and validity data. The CSOS assesses preschool through sixth grade classroom functioning from a systems perspective using a theoretical framework based on the Circumplex Model of Marital and Family Systems (Olson, Russell & Sprenkle, 1989). The CSOS is theoretically derived, has acceptable interobserver agreement, fair to moderate stability, and is comprised of factors consistent with conceptual components. The design of the CSOS represents a theoretical shift by changing the focus of observation from the individual child to the classroom system. The CSOS can be used in research and holds promise for clinical applications.     

Student evaluation of instruction in higher education: exploring issues of validity and reliability

Many personnel committees at colleges and universities in the USA use student evaluation of faculty instruction to make decisions regarding tenure, promotion, merit pay or faculty professional development. This study examines the construct validity and internal consistency reliability of the student evaluation of instruction (SEI) used at a large mid‐western university in the USA for both administrative and instructional purposes. The sample consisted of 73,500 completed SEIs for undergraduate students who self‐reported as freshman, sophomore, junior or senior. Confirmatory factor analysis via structural equation modelling was used to explore the construct validity of the SEI instrument. The internal consistency of students' ratings was reported to provide reliability evidence. The results of this study showed that the model fits the data for the sample. The significance of this study as well as areas for further research are discussed.     

西方哲学的逻辑发端及其致思本体的历史演变

The Relationships Among Scientific Epistemic Beliefs,Conceptions of Learning Science,and Motivation of Learning Science: A study of Taiwan high school students

This study explores the relationships among Taiwanese high school students’ scientific epistemic beliefs (SEBs), conceptions of learning science (COLS), and motivation of learning science. The questionnaire responses from 470 high school students in Taiwan were gathered for analysis to explain these relationships. The structural equation modeling technique was utilized to reveal that the students’ absolutist SEBs led to reproduced COLS (i.e. learning science as memorizing, preparing for tests, calculating, and practicing) while sophisticated SEBs were related to constructive COLS (i.e. learning science as increase of knowledge, applying, and attaining understanding). The students’ reproduced COLS were also negatively associated with surface motive of learning science, whereas the constructive COLS were positively correlated with students’ deep motive of learning science. Finally, this study found that students who viewed scientific knowledge as uncertain (advanced epistemic belief) tended to possess a surface motive of learning science. This finding implies that the implementation of standardized tests diminishes Taiwanese high school students’ curiosity and interest in engaging deeply in science learning.
