Scientific concept development in Solomon Island students: a comparative analysis

Abstract

This paper summarises the results of an investigation of Solomon Islands secondary school students’ interpretations of three concepts: vision, animals and burning. Internal comparisons among the three areas and external comparisons with findings reported from other societies are made. While some support is given to the idea that children from different cultures may develop similar conceptions, this support is qualified and is shown to be dependent on the type of phenomenon investigated. The degree to which there is immediate personal experience of phenomena may be important, as may the presence or absence of culturally supported explanations. The commonly reported resistance of children's conceptions to school science teaching is also shown not to be universally true. The article ends with a plea for caution in the cross‐cultural extrapolation of research into children's conceptions.     

Secondary school physics teachers' conceptions of scientific evidence: An exploratory case study

This article describes an exploratory case study of secondary school physics teachers' conceptions of scientific evidence. The nature of teachers' conceptions of evidence was derived from an analysis of data collected from 1 preservice and 2 in‐service teachers. Each teacher responded to a series of research prompts in multiple interviews and handwritten tasks. In these research prompts, the teachers thought aloud while designing experiments and critically evaluating student‐collected data as presented in hypothetical classroom scenarios. Spoken and written data were recorded. The data set was coded and analyzed using standard qualitative analysis techniques. Data from this study suggest that, while contemplating the reliability and validity of hypothetical student‐generated scientific evidence, the teachers frequently intertwined conceptions of evidence with subject matter concepts centrally relevant to the hypothetical investigation. Data also indicate that the relationship between subject matter knowledge and conceptions of evidence was more pronounced for some conceptions of evidence than for others. Results suggest that a fuller study is warranted. Suggestions for future research include exploring such relationships in other physics content areas as well as other scientific disciplines. Implications for science teacher education suggest that science and science methods courses should encourage preservice teachers to engage in original scientific research, as well as participate in peer review and critique. © 2003 Wiley Periodicals, Inc.

Variation in Student Reflections on their Conceptions of and Approaches to Learning Biochemistry in a First‐year Health Sciences’ Service Subject

Many factors affect students’ learning approaches, including topic conceptions and prior study. This research, undertaken after a first‐semester compulsory subject, explores students’ conceptions of biochemistry and how they approached their studies. Students (n=151) completed an open‐ended survey analysed phenomenographically. Those with cohesive conceptions were found to be more likely to adopt deeper approaches to study than those with fragmented conceptions, a result unaffected by various demographic parameters. Compared with earlier research, a semester of study increased the percentage of students with a cohesive view, with no concomitant change in learning approaches, suggesting that cohesive conceptions are a necessary but not sufficient criterion for deep learning outcomes. Compared with results for a science major subject, more of the students with cohesive conceptions used surface approaches. This may reflect a regression to safe surface approaches when faced with an unfamiliar topic or high total workload driving a strategic approach to learning. It could also reflect a perception that this material is only a tool for later application. The present findings indicate the crucial importance, when university studies begin, of enabling students to build an overarching conception of the topic’s place in professional practice. This concept building should be applied across the entire curriculum to emphasize application and integration of material (key graduate attributes). Improved conceptions may provide crucial motivation for students to achieve deeper learning, especially in these foundation service subjects. These essential changes to the learning context may also better prepare students for increasing self‐directed/life‐long learning.     

Why Most Children Think Well of Themselves

This research aimed to examine whether and why children hold favorable self‐conceptions (total N = 882 Dutch children, ages 8–12). Surveys (Studies 1–2) showed that children report strongly favorable self‐conceptions. For example, when describing themselves on an open‐ended measure, children mainly provided positive self‐conceptions—about four times more than neutral self‐conceptions, and about 11 times more than negative self‐conceptions. Experiments (Studies 3–4) demonstrated that children report favorable self‐conceptions, in part, to live up to social norms idealizing such self‐conceptions, and to avoid seeing or presenting themselves negatively. These findings advance understanding of the developing self‐concept and its valence: In middle and late childhood, children's self‐conceptions are robustly favorable and influenced by both external (social norms) and internal (self‐motives) forces.     

Assessment for learning? Thinking outside the (black) box

This article draws on a survey of 83 teachers, to explore the concepts of ‘assessment for learning’, ‘assessment’ and ‘learning’. ‘Assessment for learning’ is categorized as meaning: monitoring pupils' performance against targets or objectives; using assessment to inform next steps in teaching and learning; teachers giving feedback for improvement; (teachers) learning about children's learning; children taking some control of their own learning and assessment; and turning assessment into a learning event. Conceptions of assessment include assessment‐as‐measurement and assessment‐as‐inquiry. These conceptions are related to two conceptions of learning: learning‐as‐attaining‐objectives and learning‐as‐the‐construction‐of‐knowledge. The conceptions of assessment‐as‐measurement and learning‐as‐attaining‐objectives are dominant in English educational policy today. The article suggests that these conceptions need to be challenged and expanded, since conceptions held by those who have power in education determine what sort of assessment and learning happen in the classroom, and therefore the quality of the student's learning processes and products.     

Exploring alternative conceptions from Newtonian dynamics and simple DC circuits: Links between item difficulty and item confidence

Croatian 1st‐year and 3rd‐year high‐school students (N = 170) completed a conceptual physics test. Students were evaluated with regard to two physics topics: Newtonian dynamics and simple DC circuits. Students answered test items and also indicated their confidence in each answer. Rasch analysis facilitated the calculation of three linear measures: (a) an item‐difficulty measure based upon all responses, (b) an item‐confidence measure based upon correct student answers, and (c) an item‐confidence measure based upon incorrect student answers. Comparisons were made with regard to item difficulty and item confidence. The results suggest that Newtonian dynamics is a topic with stronger students' alternative conceptions than the topic of DC circuits, which is characterized by much lower students' confidence on both correct and incorrect answers. A systematic and significant difference between mean student confidence on Newtonian dynamics and DC circuits items was found in both student groups. Findings suggest some steps for physics instruction in Croatia as well as areas of further research for those in science education interested in additional techniques of exploring alternative conceptions. © 2005 Wiley Periodicals, Inc.

Students’ Conceptions of Ionisation Energy: A Cross‐cultural Study

Previous studies have indicated that A‐level students in the UK and Singapore have difficulty learning the topic of ionisation energy. A two‐tier multiple‐choice instrument developed in Singapore in an earlier study, the Ionisation Energy Diagnostic Instrument, was administered to A‐level students in the UK, advanced placement high school students in the USA, and first‐year university students in China, New Zealand, and Spain to determine whether the students from different countries and educational systems had similar conceptions and difficulties as the students in Singapore with the concepts assessed in the instrument. The results showed that, in general, the students in all six samples had similar alternative conceptions, which were grouped under the categories of octet rule framework, stable fully‐filled and half‐filled subshell conceptions, and conservation of force thinking. The students also resorted to relation‐based thinking when answering items involving the trend of ionisation energies across Period 3. Implications for teaching and further research are discussed.     

What are Finnish Teacher Educators’ Conceptions about the Teaching of Problem Solving in Mathematics?

The aim of this study was to determine Finnish teacher educators’ conceptions about problem solving, the teaching of problem solving and the prerequisites they feel its teaching requires. Teacher educators’ conceptions were collected with two questionnaires within a two‐part seminar on problem solving which was held in 1986 and 1987. Analysis of the resulting percentage tables yielded some information about the teacher educators’ conceptions about the teaching of problem solving. The highest level of consensus was obtained for statements that reflect an open‐minded approach to teaching. The consensus was lowest for the statement which stated that mathematical formalism should be stressed.     

Not all preconceptions are misconceptions: finding ‘anchoring conceptions’ for grounding instruction on students’ intuitions

This study begins the task of mapping out the domain of valid, potentially helpful beliefs of students and raises the possibility of drawing on these intuitions in teaching conceptual material. Some issues are explored surrounding the identification of such intuitions, referred to as anchoring conceptions or anchors. We attempt to: (1) propose some organizing theoretical and observational definitions of the anchor construct; (2) present some initial findings from a diagnostic test designed to uncover anchors for physics instruction; and (3) provoke an initial discussion of the new methodological issues that arise in this domain.

The results of the diagnostic test indicate that a number of group anchors exist. In addition, some unexpected non‐anchors were identified. Furthermore, evidence was found indicating that some anchoring examples may be ‘brittle’, i.e., evidence that the anchor could not be extended analogically to help a student make sense of a target situation.

Finally, it is suggested that further research is needed to construct a theory of anchoring conceptions that would, for example, specify what characteristics would indicate that an anchoring conception can provide the basis for conceptual change via analogical extension.     

Teacher Effectiveness Research: towards describing user‐friendly classroom instruction

In this article we examine the teacher's role as a mediator of knowledge and cognitive learning in the classroom. We cite findings from the research areas of teacher effectiveness, teacher expertise, and curriculum knowledge. These data strongly support user‐friendly explicit methods of classroom teaching. We also discuss issues raised in conjunction with alternative conceptions of the teaching process. Finally, we note the importance of incorporating teacher effectiveness research findings into teacher education programmes, and of identifying the various misconceptions that have been used to criticise this body of information.     

Students' Conceptions of Research. 2: An exploration of contrasting patterns of variation

This study explores variation in postgraduate students' and supervisors' conceptions of research. Based on earlier work, a Conceptions of Research Inventory (CoRI) was trialled on a mixed sample of postgraduate students and supervisors (n = 251). Exploratory factor analyses of resultant data yields a five‐dimensional empirical model, the composition of which is consistent with earlier work by the present authors. Four of these five dimensions distinguish between (variation in) conceptions of research such as “truth”, “problem‐solving”, “re‐search”, and “an insightful process”. The fifth dimension captures variation in terms of what are interpreted as “misconceptions”. The discrete conceptual dimensions suggested within the factor model are further explored via k‐means cluster analyses in terms of partitioning of the dataset, as limited by sample sizes, according to postgraduate status and supervisor designation. These analyses provide further insights into variation, across the various clusters in each case, as expressed in the profiles of cluster mean scores. Such differences as are evidenced highlight contrasting patterns of variation between, for example, experienced and novice researchers. There is also evidence of dissonance in some of the cluster solutions and it is further demonstrated via analysis of variance that dissonant cluster membership is associated with a generally lower level of self‐estimated performance. The implications of these findings are finally considered in relation to postgraduate training and supervision.     

The influence of core teaching conceptions on teachers' use of inquiry teaching practices

This article investigates three teachers' conceptions and use of inquiry‐based instructional strategies throughout a professional development program. The professional development program consisted of a 2‐week summer inquiry institute and research experience in university scientists' laboratories, as well as three academic year workshops. Insights gained from an in‐depth study of these three secondary teachers resulted in a model of teacher conceptions that can be used to direct future inquiry professional development. Teachers' conceptions of inquiry teaching were established through intensive case–study research that incorporated extensive classroom observations and interviews. Through their participation in the professional development experience, the teachers gained a deeper understanding of how to implement inquiry practices in their classrooms. The teachers gained confidence and practice with inquiry methods through developing and presenting their institute‐developed inquiry lessons, through observing other teachers' lessons, and participating as students in the workshop inquiry activities. Data analysis revealed that a set of four core conceptions guided the teachers' use of inquiry‐based practices in their classrooms. The teachers' conceptions of science, their students, effective teaching practices, and the purpose of education influenced the type and amount of inquiry instruction performed in the high school classrooms. The research findings suggest that to be successful inquiry professional development must not only teach inquiry knowledge, but it must also assess and address teachers' core teaching conceptions. © 2007 Wiley Periodicals, Inc.

Discerning Pedagogical Quality in Preschool

A well‐developed and researched conceptual framework exists for identifying undergraduate students' conceptions of learning. In addition, research has been reported on teachers' conceptions of teaching as they relate to their conceptions of learning. The research reported in this paper takes the existing framework into a new area, postgraduate supervisors' conceptions of “research”. It is hypothesized that the development of a conceptual framework that identifies postgraduate students' conceptions of “research”, and how these articulate with the conceptions of research held by their research supervisors, will enable support mechanisms to be developed and used to assist students early in their candidature. In addition, supervisory practice will benefit from being aware of, and sensitive to, the variety and potential effect of these conceptions. While it is recognized that there are strong cultural influences on conceptions of research, this project has focused initially on the conceptions of research generally adopted by Western academic institutions. However, the students involved in the study were not necessarily of a Western educational background. This paper outlines the results of research undertaken to date in identifying supervisors' conceptions. In addition, it discusses supervisors' views on: the purpose of research and what characterizes “good” research and good researchers. Various strategies reported by supervisors to assist their students to develop more comprehensive and sophisticated conceptions of research are also discussed.     

Reconceptualizing the School Administrator's Role: Socialization at Mid‐Career

School reform strategies involving restructuring require that administrators redefine their roles. Most of the research in this area has emphasized new rather than veteran administrators. However, if these reform strategies are to be implemented, school administrators at mid‐career stages will need to change their conceptions of the role.

This article identifies and examines literature concerning the major issues of socialization to a role conception, including definitions, sources, and socialization mechanisms for changing conceptions of the role. The article also presents a research agenda based on this theoretical examination that delineates research questions, relevant variables, and possible findings regarding changing role conceptions. The research agenda focuses on two major strategies of educational reform: shared decision making and schools of choice.     

Student teachers' learning about subject matter and pedagogy in education for sustainable development

This article reports on an investigation of student teachers’ learning about education for sustainable development (ESD). Phenomenographic data were collected using open proformas and interviews from student geography teachers taking the University of Oxford Post‐Graduate Certificate in Education (PGCE) in 2003–2004. The data analysis focuses on what the cohort of student teachers perceived as their learning about ESD and the sources that contribute to it. Extracts from the data illustrate their conceptions of subject matter, regarding the relevance of sustainable development for school students, its complex and contested meanings, and the challenges it presents for learning and learners. Data on conceptions of pedagogy illustrate their depth of learning about the relationship between ESD subject matter and approaches and strategies in teaching and learning, and features of pedagogy that illustrate interactive teaching strategies. Various school and university‐based sources were identified by the student teachers as leading to specific aspects of learning about ESD, although many of the accounts illustrate a combination of sources. Implications of the findings for teacher education and research in ESD are also discussed.     

Socio‐scientific controversies and students' conceptions about scientists

This article discusses the results of a mainly qualitative study into possible impacts of recent controversial socio‐scientific issues on a group of Portuguese secondary school students regarding their conceptions about scientists. The 86 participants: (1) answered a questionnaire with open‐ended questions; and (2) wrote a science fiction story involving a group of scientists working on a particular situation of her/his choice. Next, semi‐structured interviews were carried out to clarify and discuss the ideas embodied in the stories and mentioned in the questionnaire. All data underwent a process of content analysis. The socio‐scientific controversies recently discussed, and the way science and scientists are depicted in the media, seem to have produced some impact on students' conceptions about scientists. Based on the results obtained, some remarks and educational implications are discussed.

Strategies reported used by instructors to address student alternate conceptions in chemical equilibrium

This study explores general‐chemistry instructors' awareness of and ability to identify and address common student learning obstacles in chemical equilibrium. Reported instructor strategies directed at remediating student alternate conceptions were investigated and compared with successful, literature‐based conceptual change methods. Fifty‐two volunteer general chemistry instructors from 50 U.S. colleges and universities completed an interactive web‐based instrument consisting of open‐ended questions, a rating scale, classroom scenarios, and a demographic form. Survey respondents who provided responses or described remediation strategies requiring further clarification were identified (n = 6); these respondents amplified their views in separate, researcher‐led semistructured phone interviews. All 52 responding chemistry instructors reported and identified common student areas of difficulty in chemical equilibrium. They reported employing a variety of strategies to address and attempt to remediate students' alternate conceptions; however, these self‐reported strategies rarely included all four necessary conditions specified by Posner, Strike, Hewson, and Gertzog (Science Education, 66, 211–217, 1982) to stimulate conceptual change. Instructor‐identified student alternate conceptions were congruent with literature‐reported alternate conceptions of chemical equilibrium, thus providing validation support for these compilations. Implications for teaching and further research are also highlighted. © 2005 Wiley Periodicals, Inc. J Res Sci Teach 42: 1112–1134, 2005
