Enhancing the Student Experiment Experience: Visible Scientific Inquiry Through a Virtual Chemistry Laboratory

Practical work is often noted as a core reason many students take on science in secondary schools (high schools). However, there are inherent difficulties associated with classroom practical work that militate against scientific inquiry, an approach espoused by many science educators. The use of interactive simulations to facilitate student inquiry has emerged as a complement to practical work. This study presents case studies of four science teachers using a virtual chemistry laboratory (VCL) with their students in an explicitly guided inquiry manner. Research tools included the use of the Inquiry Science Implementation Scale in a ‘talk-aloud’ manner, Reformed Teaching Observation Protocol for video observations, and teacher interviews. The findings suggest key aspects of practical work that hinder teachers in adequately supporting inquiry and highlight where a VCL can overcome many of these difficulties. The findings also indicate considerations in using the VCL in its own right.

Student Learning Through Participation in Inquiry Activities: Two Case Studies in Teacher and Computer Engineering Education

The two case studies reported in this article contribute to a better understanding of how inquiry tasks and activities are employed as resourceful means for learning in higher professional education. An observation-based approach was used to explore characteristics of and challenges in students’ participation in collaborative inquiry activities in two first-year introductory courses in teacher and computer engineering education. The findings highlight that the students’ activities varied with regard to focus and structure and were shaped by the types of inquiry tasks, i.e. case analysis and project-based work, by how the inquiry process was guided and supported and the way the domain-specific knowledge resources and practices were introduced. An exploratory strategy and rather confined use of resources characterised the teacher education students’ inquiry, while collaborative programming, a trial-and-error approach and extensive use of external resources that of the engineering education students’. For the teacher students, the main challenge was to construct meaning of conceptual knowledge and to integrate different forms of knowledge as a lens for analysing practice. The computer engineering students experienced challenges with unpacking the underlying principles and knowledge black-boxed in the widely available resources. The article suggests that future research and curriculum designs should depart from a more refined understanding of inquiry as a learning means, by connecting inquiry activities to the specific knowledge domains, the type of tasks most suited to explore each of this domains and the challenges that may arise for students.     

The Gateway Science Workshop Program: Enhancing Student Performance and Retention in the Sciences Through Peer-Facilitated Discussion

Minority student attrition and underachievement is a long-standing and widespread concern in higher education. It is especially acute in introductory science courses which are prerequisites for students planning to pursue science-related careers. Poor performance in these courses often results in attrition of minorities from the science fields. This is a particular concern at selective universities where minority students enter with excellent academic credentials but receive lower average grades and have lower retention rates than majority students with similar credentials. This paper reports the first year results of a large scale peer-facilitated workshop program designed to increase performance and retention in Biology, Chemistry, and Physics at a selective research university. After adjusting for grade point average or SAT-Math score, workshop participants earned higher final grades than nonparticipants in Biology and Chemistry, but not in Physics. Similar effects on retention were found. While, positive effects of the program were observed in both majority and minority students, effect sizes were generally largest for minority students. Because of practical constraints in Physics, implementation of the program was not optimal, possibly accounting for the differential success of the program across disciplines.

Turning Crisis into Opportunity: Nature of Science and Scientific Inquiry as Illustrated in the Scientific Research on Severe Acute Respiratory Syndrome

Interviews with key scientists who had conducted research on Severe Acute Respiratory Syndrome (SARS), together with analysis of media reports, documentaries and other literature published during and after the SARS epidemic, revealed many interesting aspects of the nature of science (NOS) and scientific inquiry in contemporary scientific research in the rapidly growing field of molecular biology. The story of SARS illustrates vividly some NOS features advocated in the school science curriculum, including the tentative nature of scientific knowledge, theory-laden observation and interpretation, multiplicity of approaches adopted in scientific inquiry, the inter-relationship between science and technology, and the nexus of science, politics, social and cultural practices. The story also provided some insights into a number of NOS features less emphasised in the school curriculum—for example, the need to combine and coordinate expertise in a number of scientific fields, the intense competition between research groups (suspended during the SARS crisis), the significance of affective issues relating to intellectual honesty and the courage to challenge authority, the pressure of funding issues on the conduct of research and the ‘peace of mind’ of researchers, These less emphasised elements provided empirical evidence that NOS knowledge, like scientific knowledge itself, changes over time. They reflected the need for teachers and curriculum planners to revisit and reconsider whether the features of NOS currently included in the school science curriculum are fully reflective of the practice of science in the 21st century. In this paper, we also report on how we made use of extracts from the news reports and documentaries on SARS, together with episodes from the scientists’ interviews, to develop a multimedia instructional package for explicitly teaching the prominent features of NOS and scientific inquiry identified in the SARS research.

Teaching the Nature of Science in Physics Courses: The Contribution of Classroom Historical Inquiries

Physics and chemistry programs at the secondary school level in France recommend introducing components of the history of science (HS). Emphasis is placed on a ‘cultural’ dimension, which is poorly defined but essentially refers to elements of epistemological nature. Moreover, the few examples of activities based on HS suggested by the programs and science textbooks are means to learn scientific content and convey a reductive and false image of the nature of science (NoS). Our main issue is to examine the possibility to communicate a more authentic image of NoS with HS. We begin by demonstrating how our historical and epistemological analysis led us to distinguish different learning goals about NoS. We then show how these goals can generate classroom activities involving collective inquiry based on the implementation of documents. These documents may or may not be paired with experiments. Finally, we discuss the tensions that our choices created with science curricula and among teachers.     

Teaching the Nature of Science through Inquiry to Prospective Elementary Teachers: A Tale of Two Researchers

The teacher as researcher, Colburn, and the researcher, Bianchini, investigated Colburn's use of inquiry to teach the nature of science to prospective elementary teachers; we attempted to identify those aspects of the nature of science addressed through inquiry instruction and the varied contexts in which such insights arose. We began by videotaping small group inquiries and whole class deliberations during three units of Colburn's inquiry‐oriented general science course. We then conducted separate qualitative analyses of the resulting 20 h of videotaped data. Colburn, the teacher and informant, adopted an emic perspective and employed examples of explicit and implicit deliberations and demonstrations of the nature of science to construct his case. Bianchini also used an emic perspective, but examined only what teacher and students explicitly identified as examples of and insights into the nature of science. Taken together, our analyses highlight the difficulties in presenting a cogent and comprehensive picture of the nature of science to students, the teacher's pivotal role in initiating discussions of what science is and how scientists work, and the strengths and limitations of using classroom‐based research to investigate nature of science instruction. © 2000 John Wiley & Sons, Inc.

Examining Student Engagement with Science Through a Bourdieusian Notion of Field

Student engagement with science is a long-standing, central interest within science education research. In this article, we examine student engagement with science using a Bourdiusian lens, placing a particular emphasis on the notion of field. Over the course of one academic year, we collected data in an inner London secondary science classroom through lesson observations, interviews and discussion groups with students, and interviews with the teacher. We argue that applying Bourdieusian theory can help better understand differential patterns of student engagement by directing attention to the alignment between students’ habitus and capital, and the field. Student behaviours that did not meet the requirements of the wider field were not recognised and valued as constituting engagement. Even when the ‘rules of the game’ of the science classroom were understood by the students, the tensions they experienced within the field made engaging with science impossible and undesirable. We discuss how a greater focus on the field can be useful for planning future interventions aimed at making science education more equitable.

Drawing Nature of Science in Pre-service Science Teacher Education: Epistemic Insight Through Visual Representations

Developing pre-service science teachers’ epistemic insight remains a challenge, despite decades of research in related bodies of work such as the nature of science (NOS) in science education. While there may be numerous aspects to this problem, one critical element is that the NOS is a meta-concept that demands higher-order cognitive skills. One possible strategy to facilitate pre-service teachers’ understanding of epistemic aspects of science is visualisation. Visual representations of objects and processes can be tools for developing and monitoring understanding. Although the NOS and visualisation literatures have been studied extensively, the intersection of these bodies of literatures has been minimal. Incorporating visual tools on the NOS in teacher education is likely to facilitate teachers’ learning, eventually impacting their students’ learning of the NOS. The objective of this paper is to illustrate how the visual tools of scientific knowledge and practices aspects of the NOS can be integrated in science teacher education in order to develop pre-service teachers’ epistemic insight. The paper presents an empirical study that incorporated visual tools about the NOS in primary science teacher education. Data on 14 pre-service teachers’ are presented along with in-depth case studies of 3 pre-service teachers illustrating the influence of the teacher education intervention. The qualitative analysis of visual representations before and after the intervention as well as verbal data suggests that there was improvement in pre-service teachers’ perceptions of the NOS. Implications for future research on visualisation of the NOS are discussed.     

History of Science as an Instructional Context: Student Learning in Genetics and Nature of Science

This study (1) explores the effectiveness of the contextualized history of science on student learning of nature of science (NOS) and genetics content knowledge (GCK), especially interrelationships among various genetics concepts, in high school biology classrooms; (2) provides an exemplar for teachers on how to utilize history of science in genetics instruction; and (3) suggests a modified concept mapping assessment tool for both NOS and GCK. A quasi-experimental control group research design was utilized with pretests, posttests, and delayed posttests, combining qualitative data and quantitative data. The experimental group was taught with historical curricular lessons, while the control group was taught with non-historical curricular lessons. The results indicated that students in the experimental group developed better understanding in targeted aspects of NOS immediately after the intervention and retained their learning 2 months after the intervention. Both groups developed similar genetics knowledge in the posttest, and revealed a slight decay in their understanding in the delayed posttest.     

Electrifying Engagement in Middle School Science Class: Improving Student Interest Through E-textiles

Most interventions with “maker” technologies take place outside of school or out of core area classrooms. However, intervening in schools holds potential for reaching much larger numbers of students and the opportunity to shift instructional dynamics in classrooms. This paper shares one such intervention where electronic textiles (sewable circuits) were introduced into eighth grade science classes with the intent of exploring possible gains in student learning and motivation, particularly for underrepresented minorities. Using a quasi-experimental design, four classes engaged in a traditional circuitry unit while the other four classes undertook a new e-textile unit. Overall, students in both groups demonstrated significant learning gains on standard test items without significant differences between conditions. Significant differences appeared between groups’ attitudes toward science after the units in ways that show increasing interest in science by students in the e-textile unit. In particular, they reported positive identity shifts pertaining to their perceptions of the beliefs of their friends, family, and teacher. Findings and prior research suggest that student-created e-textile designs provide opportunities for connections outside of the classroom with friends and family and may shift students’ perceptions of their teacher’s beliefs about them more positively.     

Nature of Science,Scientific Inquiry,and Socio-Scientific Issues Arising from Genetics: A Pathway to Developing a Scientifically Literate Citizenry

The primary focus of this article is to illustrate how teachers can use contemporary socio-scientific issues to teach students about nature of scientific knowledge as well as address the science subject matter embedded in the issues. The article provides an initial discussion about the various aspects of nature of scientific knowledge that are addressed. It is important to remember that the aspects of nature of scientific knowledge are not considered to be a comprehensive list, but rather a set of important ideas for adolescent students to learn about scientific knowledge. These ideas have been advocated as important for secondary students by numerous reform documents internationally. Then, several examples are used to illustrate how genetically based socio-scientific issues can be used by teachers to improve students’ understandings of the discussed aspects of nature of scientific knowledge.

Do Singapore Science Students Possess Positive Attitudes Toward Science and Scientific Inquiry? – Implications of an Exploratory Study

There is a growing interest in attitude research in recent years since the development of positive attitudes toward science and scientific inquiry has been widely accepted as an important aim of science education. Review of the research on students' science-related attitudes shows that not many studies have been carried out in Singapore. Of the few studies related to this area, quite different variables have been examined in the search for substantial influences in students' science-related attitudes.     

The Nature of Science and Scientific Knowledge: Implications for a Preservice Elementary Methods Course

This article describes teaching considerations related to the nature of science and scientific knowledge in an elementary science methods course. The decisions that were made, the rationale upon which these decisions were based, and the challenges evident are presented. Instructional strategies used during the course for the purpose of developing preservice teachers' understandings of the nature of science and scientific knowledge are described. The results of using these strategies, in regard to the impact on students' learning and their views on teaching the nature of science to elementary grade students are then discussed. The article concludes with a discussion on the implications for teaching the nature of science and scientific knowledge in the context of preservice elementary teacher education.
