Identifying Science Understanding for Functional Scientific Literacy

Students' questions play an important role in meaningful learning and scientific inquiry. They are a potential resource for both teaching and learning science. Despite the capacity of students' questions for enhancing learning, much of this potential still remains untapped. The purpose of this paper, therefore, is to examine and review the existing research on students' questions and to explore ways of advancing future work into this area. The paper begins by highlighting the importance and role of students' questions from the perspectives of both the learner and the teacher. It then reviews the empirical research on students' questions, with a focus on four areas: (1) the nature and types of these questions; (2) the effects of teaching students questioning skills; (3) the relationship between students' questions and selected variables; and (4) teachers' responses to, and students' perceptions of, students' questions. Following this, some issues and implications of students' questions for classroom instruction are discussed. The paper concludes by suggesting several areas for future research that have significant value for student learning.     

Design principles for support in developing students’ transformative inquiry skills in Web-based learning environments

The aim of this explorative study was to find the factors limiting sixth-grade learners’ outcomes in acquiring skills related to the transformative inquiry learning processes as well as to analyse the interrelations between inquiry skills in order to develop an optimal support system for designing Web-based inquiry learning environments. A Web-based learning environment ‘Young Scientist’ was developed and applied to the domain of integrated science. The skill of identifying the correct research questions appeared to be a prerequisite for formulating research questions. When students understand how to identify the research questions correctly, there is no need for supporting formulation of research questions or hypotheses. We have found that at the stages of analysing data and inferring, students have to be provided with the tools to activate their prior knowledge, assignments help to organize their work into manageable sections, and reflective support or adaptive feedback to relate the results achieved with the process of inquiry. Our findings demonstrate that the effectiveness of inquiry learning can be strongly influenced by regulative support; however, a particular level of initial inquiry knowledge in theoretical context is also needed in order to develop inquiry skills in a situational context.     

Teacher epistemology and scientific inquiry in computerized classroom environments

A 20-week classroom-based study was conducted to investigate the extent to which a computerized learning environment could facilitate students' development of higher-level thinking skills associated with scientific inquiry. In two classes students' interactions with a scientific data base—Birds of Antarctica—were closely monitored, and the mediating roles of the teachers' epistemologies were examined. Interpretive data were generated and analyzed in relation to a constructivist perspective on learning. In the class where the teacher implemented a constructivist-oriented pedagogy, students took advantage of enhanced opportunities to generate creative questions and conduct complex scientific investigations. These higher-level thinking skills were much less evident in the class in which a more transmissionist-oriented pedagogy prevailed. The results of the study suggest that it is not the computer itself that facilitates inquiry learning; the teacher's epistemology is a key mediating influence on students' use of the computer as a tool of scientific inquiry.     

Development of system thinking skills in the context of earth system education

The current study deals with the development of system thinking skills at the junior high school level. The sample population included about 50 eighth‐grade students from two different classes of an urban Israeli junior high school who studied an earth systems‐based curriculum that focused on the hydro cycle. The study addressed the following research questions: (a) Could the students deal with complex systems?; (b) What has influenced the students' ability to deal with system perception?; and (c) What are the relationship among the cognitive components of system thinking? The research combined qualitative and quantitative methods and involved various research tools, which were implemented in order to collect the data concerning the students' knowledge and understanding before, during, and following the learning process. The findings indicated that the development of system thinking in the context of the earth systems consists of several sequential stages arranged in a hierarchical structure. The cognitive skills that are developed in each stage serve as the basis for the development of the next higher‐order thinking skills. The research showed that in spite of the minimal initial system thinking abilities of the students most of them made some meaningful progress in their system thinking skills, and a third of them reached the highest level of system thinking in the context of the hydro cycle. Two main factors were found to be the source of the differential progress of the students: (a) the students' individual cognitive abilities, and (b) their level of involvement in the knowledge integration activities during their inquiry‐based learning both indoors and outdoors. © 2005 Wiley Periodicals, Inc.     

Progressive inquiry in a computer‐supported biology class

The problem addressed in the study was whether 10‐ and 11‐year‐old children, collaborating within a computer‐supported classroom, could engage in progressive inquiry that exhibits an essential principal feature of mature scientific inquiry: namely, engagement in increasingly deep levels of explanation. Technical infrastructure for the study was provided by the Computer‐Supported Intentional Learning Environment (CSILE). The study was carried out by qualitatively analyzing written notes logged by 28 Grade 5/6 students to CSILE's database. Results of the study indicated that with teacher guidance, students were able to produce meaningful intuitive explanations about biological phenomena, guide this process by pursuing their own research questions, and engage in constructive peer interaction that helped them go beyond their intuitive explanations and toward theoretical scientific explanations. Expert evaluations by three widely recognized philosophers of science confirmed the progressive nature of students' inquiry. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 1072–1088, 2003     

Leveraging new media skills in a peer feedback tool

Today's youth thrive in informal participatory communities where they not only consume but also act as contributors or producers. Through active participation they develop new media skills encompassing cultural competencies and social skills. In a participatory culture of learning, students' active contributions to their learning are stressed and peer feedback is considered an important component. In this paper we consider how to leverage aspects of these skills and the environments in which they are developed in the design of a peer feedback tool for students engaged in collaborative inquiry learning. The tool needs to be lightweight, and “playful” and draw on these participatory skills in order to entice and motivate students to give and receive feedback.     

Personal inquiry learning trajectories in geography: technological support across contexts

Student engagement in the design and implementation of inquiries is an effective way for them to learn about the inquiry process and the domain being studied. However, inquiry learning in geography can be challenging for teachers and students due to the complexity of scientific inquiry and the diversity of pupils' and teachers' knowledge and abilities. To address this, the Personal Inquiry project has designed a tool kit that includes nQuire, a Web-based tool to support students through the inquiry process. Here, we identify when, across five lessons comprising an inquiry into microclimates, nQuire was used by a teacher and a case study group of her 12 to 13-year-old students, and the ways in which they adopted nQuire as a tool to facilitate the creation of a coherent and cumulative inquiry learning experience over time. We found that students' use of nQuire supported them in capturing and representing their evolving understanding of inquiry, in defining and supporting their progression through the process of inquiry and in resourcing their cognitive engagement in data interpretation and representation. nQuire supported the students in accumulating and integrating new understandings across contexts and over time. In this way, nQuire successfully resourced and supported the students' learning journeys or trajectories. We conclude that nQuire can be an effective tool for supporting teachers' and students' understanding of the nature of inquiry and how to design and implement inquiries of their own.     

Proofs produced by secondary school students learning geometry in a dynamic computer environment

As a key objective, secondary school mathematics teachers seek to improve the proof skills of students. In this paper we present an analytic framework to describe and analyze students' answers to proof problems. We employ this framework to investigate ways in which dynamic geometry software can be used to improve students' understanding of the nature of mathematical proof and to improve their proof skills. We present the results of two case studies where secondary school students worked with Cabri-Géeomèetre to solve geometry problems structured in a teaching unit. The teaching unit had theaims of: i) Teaching geometric concepts and properties, and ii) helping students to improve their conception of the nature of mathematical proof and to improve their proof skills. By applying the framework defined here, we analyze students' answers to proof problems, observe the types of justifications produced, and verify the usefulness of learning in dynamicgeometry computer environments to improve students' proof skills.     

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.     

Identifying patterns of students' performance on simulated inquiry tasks using PISA 2015 log-file data

Previous research has demonstrated the potential of examining log-file data from computer-based assessments to understand student interactions with complex inquiry tasks. Rather than solely providing information about what has been achieved or the accuracy of student responses (product data), students' log files offer additional insights into how the responses were produced (process data). In this study, we examined students' log files to detect patterns of students' interactions with computer-based assessment and to determine whether unique characteristics of these interactions emerge as distinct profiles of inquiry performance. Knowledge about the characteristics of these profiles can shed light on why some students are more successful at solving simulated inquiry tasks than others and how to support student understanding of scientific inquiry through computer-based environments. We analyzed the Norwegian PISA 2015 log-file data, science performance as well as background questionnaire (N = 1,222 students) by focusing on two inquiry tasks, which required scientific reasoning skills: coordinating the effects of multiple variables and coordinating theory and evidence. Using a mixture modeling approach, we identified three distinct profiles of students' inquiry performance: strategic, emergent, and disengaged. These profiles revealed different characteristics of students' exploration behavior, inquiry strategy, time-on-task, and item accuracy. Further analyses showed that students' assignment to these profiles varied according to their demographic characteristics (gender, socio-economic status, and language at home), attitudes (enjoyment in science, self-efficacy, and test anxiety), and science achievement. Although students' profiles on the two inquiry tasks were significantly related, we also found some variations in the proportion of students' transitions between profiles. Our study contributes to understanding how students interact with complex simulated inquiry tasks and showcases how log-file data from PISA 2015 can aid this understanding.     

Affordances and constraints of computers in science education

Throughout the 1970s and 1980s, computers in science teaching were seen as a panacea for many problems plaguing the domain. While considerable research has been done to determine cognitive achievements of students who interact with computers during their science learning, more basic questions have not yet been addressed. This study was designed to investigate how computers and a modeling software contributed to students' interactions and learning in a physics course. The interpretations focused on the microworld as a tool that supported but also limited students' sense-making activities. First, the computer microworld contributed in significant ways to the maintenance and coordination of students' physics conversations. Second, the computer environment (a) was sometimes “unready to hand” so that students spent more time learning the software rather than physics, and (b) limited the interactions within groups. It was concluded that while computer environments have some potential as learning tools, they also limit interactions in significant ways, rendering them less than ideal for everyday classroom use. With the use of software … students can be provided with the necessary tools and experiences to practice the investigative skills used by scientists and mathematicians… [Students] can pursue specific topics of their own interest and deal with this information in sufficient depth to construe personal meaning to various concepts. (Barman, 1993, p. viii) In educational applications, user interface design has received little attention, despite the fact that the interface is particularly important for educational software… This concern goes much deeper than the nebulous concept most often represented by the buzz phrase, ‘user friendliness.’ (Jackson, Edwards, & Berger, 1993b, p. 414) © 1996 John Wiley & Sons, Inc.     

A framework for scaffolding students' assessment of the credibility of evidence

Assessing the credibility of evidence in complex, socio‐scientific problems is of paramount importance. However, there is little discussion in the science education literature on this topic and on how students can be supported in developing such skills. In this article, we describe an instructional design framework, which we call the Credibility Assessment Framework, to scaffold high school students' collaborative construction of evidence‐based decisions and their assessment of the credibility of evidence. The framework was employed for the design of a web‐based reflective inquiry environment on a socio‐scientific issue, and was enacted with 11th grade students. The article describes the components of the Credibility Assessment Framework and provides the details and results of an empirical study illustrating this framework in practice. The results are presented in the form of a case study of how 11th grade students investigated and evaluated scientific data relating to the cultivation of genetically modified plants. Multiple kinds of data were collected, including pre‐ and post‐tests of students' conceptual understanding and their skills in assessing the credibility of evidence, and videotapes of students' collaborative inquiry sessions. The analysis of the pre‐ and post‐tests on students' conceptual understanding of Biotechnology and their skills in assessing the credibility of evidence revealed statistically significant learning gains. Students' work in task‐related artifacts and the analysis of two groups' videotaped discussions showed that students became sensitive to credibility criteria, questioned the sources of data and correctly identified sources of low, moderate, and high credibility. Implications for designers and educators regarding the application of this framework are discussed. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 48: 711–744, 2011     

Developing understanding through confronting varying views: The case of solving qualitative physics problems

This study explored high school students' collaborative efforts in solving qualitative physics problems. It aims to investigate whether and how confronting students with varying views help to improve their problem solving skills and develop better understanding of the underlying physics concepts. The varying views were provided to 18 Year 12 students by requiring them (a) to work in dyads on three problems during which they had to consider and confront each other's ideas; and (b) to consider, in a feedback session, multiple solutions to each problem, comparing the solutions with their own and reflecting on their mistakes. The study adopts Marton's emerging theory of awareness as its theoretical underpinning- that the varying views would bring to students' focal awareness and enable them to discern the different critical aspects of the problem situations and this would help them to develop conceptual understanding. The results show that confronting students with varying views have positive effects on students' learning, thus lending support to the theory of awareness.     

Question‐posing capability as an alternative evaluation method: Analysis of an environmental case study

An effective strategy for improving problem‐solving ability is fostering students' question‐posing capabilities through the use of real‐world problems. This article describes research on scientific question‐posing capabilities among 10th‐grade students who were studying air quality in a cooperative way, using the jigsaw method. Case studies and analyses of daily problems and dilemmas were integrated within the module the Quality of Air around Us, which was designed and developed specially for this research. The students were required to pose questions and cope with real‐life problems while practicing a variety of learning activities, such as reading press or scientific articles, analyzing tables and graphs, and creating posters and advertisements that related to the problem. The students' question‐posing skills were evaluated by using pre‐ and postcase study questionnaires. We found the number, orientation, and complexity of questions students posed to be three indices of question‐posing capability. Following study of the Quality of Air around Us module, a significant increase was observed in the factors of number and complexity of questions students posed. The difference between students at high and low academic levels in the extent of increase in both number and complexity of posed questions was significant. As for orientation, the percentage of solution‐ and opinion‐oriented questions increased in the posttest, and fewer questions dealt with the problem and related hazards. This indicates an increase in students' awareness of the need for and feasibility of seeking practical solutions to a given problem, as well as considerable improvement of their ability to analyze a related case study. On the basis of these findings, we recommend incorporating analysis of question‐posing capability as an alternative evaluation method. To this end, fostering of question posing into the case study–based teaching/learning approach is the preferred strategy, in particular when environmental aspects are involved. © 1999 John Wiley & Sons, Inc.

Physics students' epistemologies and views about knowing and learning

Classrooms are complex environments in which curriculum, students, and teachers interact. In recent years a number of studies have investigated the effect of teachers' epistemologies on the classroom environment, yet little is known about students' epistemologies and how these interact with those of teachers. The purpose of this study was to document students' epistemologies and their concurrent views about knowing and learning. Using a written essay, short-answer responses to statements, a preferred classroom environment inventory, and interviews, students' views on scientific knowledge and their own knowing and learning were collected from 42 students in three sections of an introductory physics course. Our rather broad, qualitative inquiry provides a dynamic view of students' understanding of knowing and learning in high school physics. Our analyses reveal a spectrum of epistemological commitments commensurable with positions from objectivism to relativism, most of them with experientialist coloring. Even within individuals, these commitments could be at once commensurable and incommensurable with the same epistemological position. We also find rather significant inter- and intra-individual differences with respect to the consequences of a specific epistemological stance to learning, the learning strategies employed, and the learning environment preferred. Students' views on knowing and learning in physics are presented in the form of an emergent theory. The findings are discussed in terms of their application to classroom environments.     

Changes in Students' Use of Lifelong Learning Skills During a Problem‐based Learning Project

ABSTRACT In a climate of continual change and innovation, lifelong learning is a critical professional development objective which has a direct impact on organizations' effectiveness and ability to compete and innovate. To help learners continually upgrade their skills and knowledge so they can effectively address emerging organizational and professional needs and opportunities, educators must prepare learners for their professions using teaching methodologies that develop learners' capacity for and disposition toward lifelong learning. Problem‐based learning (PBL) is one such method. PBL uses professional problems of practice as a starting point, stimulus, and focus for student activity, and one of PBL's stated educational outcomes is students' use of lifelong learning skills. This study examined the changes in students' use of lifelong learning skills while participating in a PBL project. Twenty‐six undergraduate university computer science students completed a 15‐week C++ programming course. Using guided reflective journal responses as process data, students were observed to increase their application of lifelong learning skills during their PBL experience. Design and research recommendations are shared.     

Affordances of ICT in science learning: implications for an integrated pedagogy

This paper presents an analysis of how affordances of ICT‐rich environments identified from a recent review of the research literature can support students in learning science in schools within a proposed framework for pedagogical practice in science education. Furthermore other pedagogical and curriculum innovations in science education (promoting cognitive change, formative assessment and lifelong learning) are examined to see how they may be supported and enhanced by affordances of ICT‐rich environments. The affordances that I have identified support learning through four main effects: promoting cognitive acceleration; enabling a wider range of experience so that students can relate science to their own and other real‐world experiences; increasing students' self‐management; and facilitating data collection and presentation. ICT‐rich environments already provide a range of affordances that have been shown to enable learning of science but integrating these affordances with other pedagogical innovations provides even greater potential for enhancement of students' learning.     

Chemical understanding and graphing skills in an honors case‐based computerized chemistry laboratory environment: The value of bidirectional visual and textual representations

The case‐based computerized laboratory (CCL) is a chemistry learning environment that integrates computerized experiments with emphasis on scientific inquiry and comprehension of case studies. The research objective was to investigate chemical understanding and graphing skills of high school honors students via bidirectional visual and textual representations in the CCL learning environment. The research population of our 3‐year study consisted of 857 chemistry 12th grade honors students from a variety of high schools in Israel. Pre‐ and postcase‐based questionnaires were used to assess students' graphing and chemical understanding–retention skills. We found that students in the CCL learning environment significantly improved their graphing skills and chemical understanding–retention in the post‐ with respect to the prequestionnaires. Comparing the experimental students to their non‐CCL control peers has shown that CCL students had an advantage in graphing skills. The CCL contribution was most noticeable for experimental students of relatively low academic level who benefit the most from the combination of visual and textual representations. Our findings emphasize the educational value of combining the case‐based method with computerized laboratories for enhancing students' chemistry understanding and graphing skills, and for developing their ability to bidirectionally transfer between textual and visual representations. © 2008 Wiley Periodicals, Inc.
