Learning about evolution and rejecting a belief in special creation: Effects of reflective reasoning skill,prior knowledge,prior belief and religious commitment

Students in three sections of a high school biology course were taught a unit on evolution and natural selection. Prior to instruction, students were pretested to determine their (a) reflective reasoning skill, (b) strength of religious commitment, (c) prior declarative knowledge of evolution and natural selection, and (d) beliefs in evolution or special creation and related religiously oriented beliefs. Following instruction the measures of declarative knowledge and beliefs were readministered. The study was designed to test (a) the hypothesis that the acquisition of domain-specific concepts and the modification of nonscientific beliefs largely depends upon reflective reasoning skill, not prior declarative knowledge; and (b) the hypothesis that strength of religious commitment and a belief in special creation hinder the acquisition of scientific beliefs. Although instruction produced no overall shift toward a belief in evolution, as predicted, reflective reasoning skill was significantly related to initial scientific beliefs, and reflective reasoning skill, but not prior declarative knowledge, was significantly related to gains in declarative knowledge. Reflective reasoning skill, however, was not significantly related to changes in beliefs. Also as predicted, strength of religious commitment was negatively correlated with initial belief in evolution and with a change in belief toward evolution. Interrelationships among the study's major variables, as well as educational implications, are discussed.     

Effects of collaborative group composition and inquiry instruction on reasoning gains and achievement in undergraduate biology

This study compared the effectiveness of collaborative group composition and instructional method on reasoning gains and achievement in college biology. Based on initial student reasoning ability (i.e., low, medium, or high), students were assigned to either homogeneous or heterogeneous collaborative groups within either inquiry or didactic instruction. Achievement and reasoning gains were assessed at the end of the semester. Inquiry instruction, as a whole, led to significantly greater gains in reasoning ability and achievement. Inquiry instruction also led to greater confidence and more positive attitudes toward collaboration. Low-reasoning students made significantly greater reasoning gains within inquiry instruction when grouped with other low reasoners than when grouped with either medium or high reasoners. Results are consistent with equilibration theory, supporting the idea that students benefit from the opportunity for self-regulation without the guidance or direction of a more capable peer.     

Variable uses of alternative conceptions: A case study in current electricity

Recent research related to the design of science instruction is often based on conceptual change theory and requires assessments of what knowledge students bring to instruction. The premise of this study was that it is also important to understand when and how students apply their knowledge. Fourteen elementary and middle school teachers in an in-service physics course were asked to solve qualitatively a variety of series and parallel circuit problems and explicate their reasoning. These teachers were found to share a common core of strongly held propositions that formed a coherent, but incorrect and contradictory model of sequential current flow. Yet their predictions about the circuits were highly variable. The variability in predictions resulted from differences and contradictions in additional “protective belts” of propositions, and differences in the ways in which the teachers changed and selectively applied those propositions to different problems. Understanding the variations in not only what teachers knew, but also the differences in when and how they applied their knowledge complicated the task of designing instruction. However, it also made possible the design of more precise instruction in which the teachers were required to recognize, confront, and reconcile specific inconsistencies in their beliefs.     

Young children learning about living things: A case study of conceptual change from ontological and social perspectives

Although research from a developmental/psychological perspective indicates that many children do not have a scientific understanding of living things, even by the age of 10 years, little research has been conducted about how students learn this science topic in the classroom. This exploratory research used a case‐study design and qualitative data‐collection methods to investigate the process of conceptual change from ontological and social perspectives when Year 1 (5‐ and 6‐year‐old) students were learning about living things. Most students were found to think about living things with either stable, nonscientific or stable, scientific framework theories. Transitional phases of understanding also were identified. Patterns of conceptual change observed over the 5‐week period of instruction included theory change and belief revision as well as reversals in beliefs. The predominant pattern of learning, however, was the assimilation of facts and information into the students' preferred framework theory. The social milieu of the classroom context exposed students' scientific and nonscientific beliefs that influenced other individuals in a piecemeal fashion. Children with nonscientific theories of living things were identified as being least able to benefit from socially constructed, scientific knowledge; hence, recommendations are made for teaching that focuses on conceptual change strategies rather than knowledge enrichment. © 2004 Wiley Periodicals, Inc.

Effects of traditional and discovery instructional approaches on learning outcomes for learners of different intellectual development: A study of chemistry students in Zambia

This study examined the differential effectiveness of traditional and discovery methods of instruction for the teaching of science concepts, understandings about science, and scientific attitudes, to learners at the concrete and formal level of cognitive development. The dependent variables were achievement, understanding science, and scientific attitude; assessed through the use of the ACS Achievement Test (high school chemistry, Form 1979), the Test on Understanding Science (Form W), and the Test on Scientific Attitude, respectively. Mode of instruction and cognitive development were the independent variables. Subjects were 120 Form IV (11th grade) males enrolled in chemistry classes in Lusaka, Zambia. Sixty of these were concrete reasoners (mean age = 18.23) randomly selected from one of the two schools. The remaining 60 subjects were formal reasoners (mean age 18.06) randomly selected from a second boys' school. Each of these two groups was randomly split into two subgroups with 30 subjects. Traditional and discovery approaches were randomly assigned to the two subgroups of concrete reasoners and to the two subgroups of formal reasoners. Prior to instruction, the subjects were pretested using the ACS Achievement Test, the Test on Understanding Science, and the Test on Scientific Attitude. Subjects received instruction covering eight chemistry topics during approximately 10 weeks. Posttests followed using the same standard tests. Two-way analysis of covariance, with pretest scores serving as covariates was used and 0.05 level of significant was accepted. Tukey WSD technique was used as a follow-up test where applicable. It was found that (1) for the formal reasoners, the discovery group earned significantly higher understanding science scores than the traditional group. For the concrete reasoners mode of instruction did not make a difference; (2) overall, formal reasoners earned significantly higher achievement scores than concrete reasoners; (3) in general, subjects taught by the discovery approach earned significantly higher scientific attitude scores than those taught by the traditional approach. The traditional group outperformed the discovery group in achievement scores. It was concluded that the traditional approach might be an efficient instructional mode for the teaching of scientific facts and principles to high school students, while the discovery approach seemed to be more suitable for teaching scientific attitudes and for promoting understanding about science and scientists among formal operational learners.     

Teachers’ Beliefs That Matter in Secondary Mathematics Classrooms

This paper reports the findings of a study that sought to identify particular centrally held beliefs of secondary mathematics teachers that underpinned the establishment of classroom environments that were consistent with the principles of constructivism. The nine crucial beliefs identified were held by one or other of two teachers and emerged from teacher and student surveys, interviews with the teachers and classroom observations. As is the case with all beliefs, these beliefs were contextually bound but since the contexts in which they applied were broader than particular classrooms it is argued that they may be generalisable to other contexts and even predictive of teachers likely to create similar classroom environments.     

Scientists' views of science,models of writing,and science writing practices

Written and oral communications and the processes of writing and reading are highly valued within the scientific community; scientists who communicate well are successful in gaining recognition and support from members of their own communities, the research funding agencies, and the wider society. Yet how do scientists achieve this proficiency? Are expert scientists equally expert writers in and of science? Do scientists' perceptions of the nature of science influence their writing strategies and processes, and their beliefs about the role of writing in knowledge construction? This study used a questionnaire and semistructured interviews to document these perceptions, strategies, processes, and beliefs in a nonrandom sample of Canadian university scientists and engineers. The results indicate that the scientists subscribed to a contemporary evaluativist view of science, used common writing strategies, held similar beliefs about scientific writing and nonscientific writing, and agreed that writing generates insights and clarifies ambiguity in science. The engineers held a different view of technology than the common views of science or technology as simply applied science. These findings were slightly different than those found for American scientists from a large land‐grant university. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 338–369, 2004     

The role of instructional variables in conceptual change in high school physics topics

This study was conducted to determine the effect of three variables on conceptual change in physics. Ninth and 10th-grade students who, despite instruction, still held nonscientific intuitive ideas about the motion of objects participated in viewing a demonstration, engaged in student-to-student discussion, and/or read a refutational text about Newton's laws of motion. Students (N = 310) were randomly assigned within classes to eight groups representing combinations of the three activities and participated in pretesting, instruction, and posttesting. Posttest results revealed that reading the refutational text helped students change their intuitive ideas to scientific ones, while seeing a demonstration affected how students interacted with group and text on some measures. Discussing ideas in a group did not lead to significant learning of scientific notions but, rather, caused students to be less influenced by either the demonstration or the text.     

Multiple learning communities: students,teachers, instructional designers,and researchers

Fostering a Community of Learners (FCL) exemplifies a class of pedagogical approaches aimed at having students become reasoners and sense‐makers in various content domains. While the pedagogical practices among these approaches vary to some degree, they tend to overlap in philosophy and general pedagogical style. Hence issues confronted by those attempting to implement FCL will be confronted by those hoping to implement similar activities. The three‐level commentary in this paper begins with specific reactions to the preceding papers, which focused on attempts to implement FCL in different content areas. It continues with a discussion of what counts in FCL: for example, is it a set of participant structures such as jigsawing, or a set of underlying principles? It concludes with a discussion of systemic issues that will be faced by any pedagogical approach focusing on having students engage in reasoning and sense‐making in the classroom.     

Using reasoning ability as the basis for assigning laboratory partners in nonmajors biology

Students in a large one-semester nonmajors college biology course were classified into one of three groups (intuitive—I, transitional—T, reflective—R) based upon a pretest of scientific reasoning ability. Laboratory teams of two students each then were formed, such that all possible combinations of reasoning abilities were represented (i.e., I-I, I-T, I-R, T-T, T-R, R-R). Students worked with their assigned partners during each of the course's 14 laboratory sessions. Gains in reasoning ability, laboratory achievement, and course achievement, as well as changes in students' opinions of their motivation, enjoyment of the laboratory, and their own and their partner's reasoning abilities were assessed at the end of the semester. Significant pre- to posttest gains in reasoning ability by the intuitive and transitional students were found, but these gains were not significantly related to the laboratory partner's reasoning ability. Also, course achievement was not significantly related to the laboratory partner's reasoning ability. Students were perceptive of others' reasoning ability; the more able reasoners were generally viewed as being more motivated, having better ideas, and being better at doing science. Additional results also indicated that course enjoyment and motivation was significantly decreased for the transitional students when they were paired with intuitive students. Apparently, for students in transition (i.e., not at an equilibrium state with regard to reasoning level), it is frustrating to work with a less able reasoner. However, some evidence was found to suggest that reflective students may benefit from working with a less able partner.     

The Effect of Inference Training on Skilled and Less Skilled Comprehenders

This paper assess the impact of introducing inference training to skilled and less skilled comprehenders. Children aged between 6 years 6 months and 9 years 11 months, classified as skilled or less skilled comprehenders, were instructed on how to make inferences from and generate questions about a text over a period of six sessions. Comparison groups of skilled and less skilled comprehenders were trained in standard comprehension strategies. The less skilled group showed a significantly greater improvement than the skilled group, regardless of the training given, but inference training was significantly more effective than standard comprehension strategies in the less skilled group. Seven out of ten less skilled readers who were inference trained increased their performance sufficiently to become classified as skilled comprehenders, whilst four out of ten less skilled comprehenders taught standard comprehension strategies improved to the same level. It is concluded that the value of explicitly teaching children inferential skills is that the enjoyment of the task of reading is enhanced and is therefore more likely to be undertaken readily, even by pupils who may have initially found reading difficult.     

Knowledge Integration and Displaced Volume

This study contrasted spontaneous and reflective knowledge integration instruction delivered using a computer learning environment to enhance understanding of displaced volume. Both forms of instruction provided animated experiments and required students to predict outcomes, observe results, and explain their ideas. In addition, the reflective instruction diagnosed specific inconsistencies in student reasoning and encouraged students to reflect on these dilemmas as well as to construct general principles. We distinguished the impact of instruction on students who believed scientific phenomena are governed by principles (cohesive beliefs) versus students who believed that science is a collection of unrelated facts (dissociated beliefs). Students typically held multiple models of displacement, using different explanations depending on the form of assessment. For example, we found that 17% of these middle school students made accurate predictions about displacement experiments prior to instruction and 25% could construct an accurate general principle. However, only 12% consistently used the same explanation across assessments. After instruction, students were more accurate and more consistent: over 50% accurately predicted experimental outcomes, 79% gave an accurate general principle, and about 40% gave consistent responses. We found no advantages for enhanced animations over straightforward animated experiments. The reflective integration instruction led to more substantial long-term changes in student understanding than did spontaneous integration instruction. Furthermore, on a delayed posttest we found that students with cohesive beliefs not only sustained their understanding of displaced volume, but, when exposed to reflective integration instruction, actually continued to construct more predictive views following instruction. In contrast, students with dissociated beliefs made no long-term progress independent of the form of instruction.     

Scientific reasoning during adolescence: The influence of instruction in science knowledge and reasoning strategies

The mechanism linking instruction in scientific topics and instruction in logical reasoning strategies is not well understood. This study assesses the role of science topic instruction combined with logical reasoning strategy instruction in teaching adolescent students about blood pressure problems. Logical reasoning instruction for this study emphasizes the controlling-variables strategy. Science topic instruction emphasizes variables affecting blood pressure. Subjects receiving logical reasoning instruction link their knowledge of blood pressure variables to their knowledge of controlling variables more effectively than those receiving science topic instruction alone—their specific responses show how they attempt to integrate their understanding.     

The Impact of a Technology Coordinator's Belief System upon Using Technology to Create a Community's History

As it has been shown that teachers of social studies content are less likely than teachers of other content areas to utilize technology in their classroom, this study focuses on one instructional technology coordinators’ beliefs towards technology, instruction, and students and how these beliefs impacted how technology was utilized during a technology-enriched community history project with a group of fourth-grade students. It was determined that the instructional technology coordinators’ beliefs included the following: (a) technology should serve as a tool and should be seamlessly integrated into the curriculum; (b) the teacher should construct meaningful experiences that allow students to become engaged in the learning process; however, before guiding student discovery, the teacher needs to explicitly teach basic technological skills; (c) and all students are able to learn and are capable of engaging in independent problem solving and critical thinking at some level. Her beliefs manifested themselves daily, particularly in the way that she approached instruction and integrated technology seamlessly into the curriculum. Through this study, it was found that the technology coordinator's beliefs toward technology, instruction, and her students directly impacted how technology was used in her classroom.     

On engaging with others: A Wittgensteinian approach to (some) problems with deeply held beliefs

Abstract

My starting point for this paper is a problem in critical thinking pedagogy—the difficult of bringing students to a point where they are able, and motivated, critically to evaluate their own deeply held beliefs. I first interrogate the very idea of a deeply held belief, drawing upon Wittgenstein’s idea of a framework belief—a belief that forms part of a ‘scaffolding’ for our thoughts—or of a belief that functions as a hinge around which other beliefs pivot. I then examine the role of deeply held beliefs, thus conceived, in our ways of being in the world, exploring the extent to which engagement with others whose deeply held beliefs differ from ours may be possible through imaginative ‘travel’. Finally, I reflect upon the extent to which these imaginative moments also offer up opportunities for critical reflection upon our own deeply held beliefs and, thus, the possibility of changing or adapting those beliefs.     

Preservice Science Teachers' Beliefs About Teaching and Learning: The Influence of K-12 Field Experiences

Teaching is a complex task shaped by many external and internal influences, including the beliefs held by individual teachers. This study sought an understanding of the impact of field experiences on the beliefs developed by preservice science teachers. The participants were students in an undergraduate science education methods course that involved observation and teaching experiences in K-12 classrooms. The data used in this qualitative study included drawings representing beliefs and in-depth interviews with selected participants. The findings indicate that beliefs focused on two key dualities: learning through experience and transmission and student-centered and teacher-centered instruction. The findings also suggest that field experiences both reinforce and challenge the beliefs held by preservice science teachers.     

Chemistry teaching objectives in Italian secondary schools

Responses to a written beliefs test for 178 eighth grade students and interviews with a subset of the students are analysed to investigate students' beliefs about the tentativeness of scientific knowledge and about the autonomy and strategies appropriate for science learning. These three dimensions of beliefs are salient because they align with the image of science teaching promoted by current reform movements. Analyses focus on change in beliefs and relationships among dimensions of beliefs and between those beliefs and students' understandings of science concepts. Results show that students' beliefs do not change much during the one-semester course. Students who view scientific knowledge as tentative also try to understand science. Autonomous students do not hold the most productive learning strategies, though students with low autonomy develop significantly less coherent understandings of science concepts. Instructional implications focus on potential roles of teachers and technology in promoting productive beliefs about scientific knowledge and science learning. Implications for individualized instruction follow classroom-level implications.     

Mathematical myths: Teacher candidates' beliefs and the implications for teacher educators

Abstract

For more than 2 decades, professional, state, and federal agencies have adopted educational standards aimed at improving mathematics instruction. One way of measuring the success of these adopted standards is to examine their impact on the mathematics attitudes and beliefs of students who received their education during this reform period. How teachers approach and implement these mathematics standards is heavily influenced by what they believe about mathematics content and pedagogy. For those who seek to improve mathematics education, examining beliefs regarding mathematics and the factors that influence those beliefs is imperative. In this paper we explore the persistence of teacher candidates' beliefs in myths despite changing educational standards. The beliefs of 76 current elementary teacher candidates were compared to beliefs of 131 elementary teacher candidates from 1990. The results confirm the pervasiveness and persistence of math myths among female elementary teacher candidates.     

The explanation of practice: Why Chinese students copy assignments

Empirical research on copying and cheating in high school and university has typically employed quantitative survey methods. While these methods tell us about the conditions under which it is more and less likely to occur, they tell us less about the reasoning that leads students to copy the work of others. An alternative problem-based methodology (PBM) is presented which treats copying as a student'ssolution to the problem of how to complete an assignment, and investigates it by inquiry into the problem-solving processes that give rise to it. The methodology is employed in a study of copying among a small sample of Chinese university students. Intensive probing of their reasoning revealed the beliefs, motives and contextual conditions that led them to copy. Copying was a habitual strategy of both strong and weak students and was motivated by a wish to obtain the desired grade in the most efficient manner possible. The findings are discussed in terms of explanatory adequacy and implications for intervention.     

Changes in Belief Orientations of Preservice Teachers and Their Relation to Inquiry Activities

Research in science education suggests that teachers?? beliefs are linked to the use of inquiry-based instruction; teachers holding a constructivist belief are more likely to engage in student-centered activities in the classroom. However, there is currently little research on the ways in which teachers?? beliefs change over time, and in particular, the relationship between instructional activities in teacher education programs and their impact on teachers?? beliefs. We examined shifts in secondary preservice teachers?? belief orientations as they progressed through a science methods course. We found that overall many of the preservice teachers progressed in their orientation beliefs from a teacher-centered orientation to more student-centered orientation. We characterized four trajectories of change or clusters that describe how preservice teachers?? beliefs changed over the course of the semester (15?weeks). We also describe the different ways in which preservice teachers reacted to specific instructional activities, and how those activities influenced their belief orientation. In particular, we found that preservice teachers in a cluster that exhibited a particular trajectory (progression or regression toward/away from student-centered belief orientation) reacted differently to some activities compared to preservice teachers in some other clusters. We discuss these shifts as reflecting changes in priorities of beliefs within belief systems. We argue that teacher educators need to think carefully about the interplay of these beliefs when designing activities so that they can respond (i.e., to a reversal in beliefs) during the course rather than waiting until the end.
