‘Let your data tell a story:’ climate change experts and students navigating disciplinary argumentation in the classroom

ABSTRACT

Science education trends promote student engagement in authentic knowledge in practice to tackle personally consequential problems. This study explored how partnering scientists and students on a social media platform supported students’ development of disciplinary practice knowledge through practice-based learning with experts during two pilot enactments of a project-based curriculum focusing on the ecological impacts of climate change. Through the online platform, scientists provided feedback on students' infographics, visual argumentation artifacts that use data to communicate about climate change science. We conceptualize the infographics and professional data sets as boundary objects that supported authentic argumentation practices across classroom and professional contexts, but found that student generated data was not robust enough to cross these boundaries. Analysis of the structure and content of the scientists’ feedback revealed that when critiquing argumentation, scientists initiated engagement in multiple scientific practices, supporting a holistic rather than discrete model of practice-based learning. While traditional classroom inquiry has emphasized student experimentation, we found that engagement with existing professional data sets provided students with a platform for developing expertise in systemic scientific practices during argument construction. We further found that many students increased the complexity and improved the visual presentation of their arguments after feedback.     

Re-negotiating the discourse of lower track high school students

The purpose of this study was to examine how lower track science students would understand shifts in standard classroom discourse patterns. The researcher videotaped his daily efforts to renegotiate the lower track classroom environment to become more representative of a scientific community. This paper is an analysis of the implicit obstacles inherent in shifting class discussions to classroom arguments examining tentative hypotheses. Students have inserted struggles for social status into classroom arguments about scientific ideas making it difficult to separate in a group discussion when the evidence convinced a student or whether the social politics of the class had persuaded her. As a result of changing classroom rules for participation, engagement, and collaborative inquiry, students' abilities to argue scientifically were changed. Despite these shifts students continued to insert their own interpretations of argumentation, social norms, and strategies for active re-negotiation of the teacher's agenda for the construction of scientific classroom discourse.     

Design and Reflection Help Students Develop Scientific Abilities: Learning in Introductory Physics Laboratories

Design activities, when embedded in an inquiry cycle and appropriately scaffolded and supplemented with reflection, can promote the development of the habits of mind (scientific abilities) that are an important part of scientific practice. Through the Investigative Science Learning Environment (ISLE), students construct physics knowledge by engaging in inquiry cycles that replicate the approach used by physicists to construct knowledge. A significant portion of student learning occurs in ISLE instructional labs where students design their own experiments. The labs provide an environment for cognitive apprenticeship enhanced by formative assessment. As a result, students develop interpretive knowing that helps them approach new problems as scientists. This article describes a classroom study in which the students in the ISLE design lab performed equally well on traditional exams as ISLE students who did not engage in design activities. However, the design group significantly outperformed the non-design group while working on novel experimental tasks (in physics and biology), demonstrating the application of scientific abilities to an inquiry task in a novel content domain. This research shows that a learning environment that integrates cognitive apprenticeship and formative assessment in a series of conceptual design tasks provides a rich context for helping students build scientific habits of mind.     

Developing an Initial Learning Progression for the Use of Evidence in Decision-Making Contexts

This paper outlines an initial learning progression for the use of evidence to support scientific arguments in the context of decision-making. Use of evidence is a central feature of knowledge evaluation and, therefore, of argumentation. The proposal is based on the literature on argumentation and use of evidence in decision-making contexts. The objective is to develop a construct map describing a trajectory of evidence use in a decision-making context. The levels in the initial learning progression are characterised by students’ performance in practice. The framework is applied to a multiple-case study in 10th grade (66 students), structured around a marine resource management task. Data included audio and video recordings, as well as students’ written artefacts. Five levels of complexity in student performance are described; on the lowest level, students are able to identify and extract information in response to a problem and recognise general features in a set of data; on the uppermost level, they are able to articulate arguments by synthesising evidence from multiple sources and evaluate options based on evidence and scientific content. The framework also shows potential for recognising students’ difficulties in identifying and integrating data and evidence in their justifications and in drawing from domain knowledge to interpret evidence. Implications for educational practice are discussed.     

Missed Opportunities for Science Learning: Unacknowledged Unscientific Arguments in Asynchronous Online and Face-to-Face Discussions

We explored the scientific argumentation that occurs among university biology students during an argumentation task implemented in two environments: face-to-face in a classroom and online in an asynchronous discussion. We observed 10 student groups, each composed of three students. Our analysis focused on how students respond to their peers’ unscientific arguments, which we define as assertions, hypotheses, propositions, or explanations that are inaccurate or incomplete from a scientific perspective. Unscientific arguments provide opportunities for productive dissent, scientific argumentation, and conceptual development of scientifically desirable conceptions. We found that students did not respond to the majority of unscientific arguments in both environments. Challenges to unscientific arguments were expressed as a question or through explanation, although the latter was more common online than face-to-face. Students demonstrated significantly more epistemic distancing in the face-to-face environment than the online environment. We discuss the differences in discourse observed in both environments and teaching implications. We also provide direction for future research seeking to address the challenges of engaging students in productive scientific argumentation in both face-to-face and online environments.     

Sociocognitive roles in science group discourse

The purpose of this study was to examine students' roles during a long-term collaborative task that required them to master complex sets of cognitive, regulatory and social skills needed for building knowledge largely from their own and their peers' ideas and observations. Samples of discourse were collected from 24 8th grade students in eight groups within four classrooms throughout a 12-week unit on constructing and testing mental models of the nature of matter. Eight prominent sociocognitive roles that served socio-emotional, conceptual and metacognitive functions are described. The roles are related to individual students' perspectives on learning, and to the levels of reasoning each group achieved. The results can be used to raise students' and teachers' awareness of the personal resources, interactive processes and norms that can support or derail knowledge construction in collaborative groups.     

The effect of integrated course and faculty development: Experiences of a university chemistry department in the Philippines

It is widely recognized that lectures continue to dominate college chemistry instruction, especially in developing countries, and that lectures limit student intellectual engagement. To address this concern, a General Chemistry course in a Philippine university was reconstructed to implement an instructional cycle consisting of three phases: a plenary or mini‐lecture, seatwork activity, and a summary or closure. An expert instructor coached the instructors to improve their teaching. Two instructors were involved in pilot implementation and 13 instructors in a large‐scale implementation. This article describes the instructors’ adoption of the instructional cycle using qualitative and quantitative methods that involved multiple data sources. The instructional cycle and intensive coaching enabled most instructors to change their practices, shift their focus from teaching to learning, and enhance their knowledge of student learning difficulties. Nine instructors were able to significantly change their teaching and apply meaningful student seatwork in their lessons. These nine instructors used student seatwork and activities 30–70% of the time, whereas previously 90% of the time involved lectures. Videotape records showed that more than 70% of the students were continuously on task. Four instructors had considerable difficulties in applying the new approach but also had difficulties with conventional lectures. The project constituted the start of a departmental reorientation with a focus on effectiveness of teaching and learning. Subsequently the faculty and course development model developed in this study was used to revise other courses. The theory of Rogan and Grayson proved useful in describing the change processes.     

Understanding the world today: the roles of knowledge and knowing in higher education

ABSTRACT

This article argues that knowledge is not a passive product of learning that can be possessed, but rather that it represents an active engagement with ideas, arguments and the world in which they reside. This engagement requires a state of ‘knowing’ – a complex, integrative, reciprocal process that unites the knower with the to-be-known. Exploring the notion of knowledge, this paper considers the roles of truth and belief in knowledge production, the relationship between knowledge and the disciplines, and knowledge as a social and cultural product. These ideas are contextualized in higher education practice with an example of a course designed to help science and engineering students develop criticality and a sense of ‘knowing’ about the world. The students are challenged to consider what it requires to turn facts and information into knowledge, and to unite their knowing with their own personal experiences and ideas about the world.     

Research Implications for Difficult to Teach Students

The relationship of academic learning time to student achievement has been demonstrated, but primarily with mainstream students. Brophy presents arguments that generalize these findings to special populations. Although it appears that academic learning time and active engagement may have similar effects on achievement for all students, the ability of teachers to successfully implement these instructional strategies for students with special needs within current administrative arrangements is questioned. The manner in which teachers allocate their resources and the problems created by attempting to teach large groups of students with heterogeneous needs is discussed.     

The relationships between social participatory roles and cognitive engagement levels in online discussions

Understanding the relationship between social interaction patterns and cognitive engagement levels has critical implications on collaborative learning theory, pedagogy, and technology. This study used a multi-method approach to examine the relationship between students' social participatory roles and cognitive engagement levels within asynchronous online discussions. Results showed that students' social participatory role was a critical indicator of cognitive engagement level. Socially active students made more cognitive contributions to knowledge inquiry and knowledge construction. But there were exceptions: after taking leadership roles (i.e., discussion designers and facilitators), some students moved from peripheral participation to active participation. Second, there was a progressive development process: individual students' deep-level knowledge inquiry could trigger peer interaction, which could further advance group knowledge construction. Third, students had a tendency to keeping social-cognitive engagement patterns throughout discussions. Based on the result, this study proposed implications for collaborative learning theory, pedagogy support, and tool development.     

Students' engagement in a science classroom: Does knowledge diversity matter?

Knowledge diversity describes group members' differences in terms of prior knowledge in a domain. The purpose of the study was to investigate whether knowledge diversity would impact students' engagement in small-group learning in a science classroom. A total of 45 seventh-grade students were recruited to participate in the study in which two experimental conditions were compared: low-prior-knowledge groups (all low-prior-knowledge students) versus mixed knowledge groups (low-prior-knowledge students with one knowledgeable student). Participates were randomly assigned into six low-prior-knowledge groups (24 individuals in total) and five mixed knowledge groups (21 individuals in total). Engagement, as well as group performance, was measured. The results of a series of independent-samples t test demonstrated that the mixed knowledge groups had significantly higher behavioral, emotional, and social engagement and better group performance than did the low-prior-knowledge groups. This implies that even having one knowledgeable student could enhance students' engagement in a science classroom.     

Knowledge building and vocabulary growth over two years, Grades 3 and 4

Productive knowledge work and high-level literacy are essential for engagement in a Knowledge society. In the research reported in this article, students were engaged in sustained collaborative knowledge building in science and social studies. The vocabulary growth of 22 students over Grades 3 and 4 was traced, based on their entries to Knowledge Forum—a knowledge building environment used as an integral part of classroom work. It is the communal space where knowledge work–ideas, reference material, results of experiments, and so forth–is entered and continually improved. Analysis of lexical frequency profiles indicated significant growth in productive written vocabulary, including academic words. In a Grade 4 inquiry, students incorporated almost all the domain-specific terms at and below their current grade level, and most of those expected for upper grade levels (5–8) based on the curriculum guidelines. Domain-specific and academic words were correlated with depth of understanding. High correlations between student engagement in knowledge building and vocabulary growth suggest that productive vocabulary can be developed through sustained knowledge building in subject areas.     

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

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

Instructional improvement and student engagement in post-secondary engineering courses: the complexity underlying small effect sizes

The current study leveraged a professional development programme for engineering faculty at a large research university to examine the impact of instructional improvement on student engagement. Professors who participated in the professional development were observed three times and rated using an existing observation protocol. Students in courses with instructors who participated and did not participate in the professional development were surveyed about their classroom engagement. The responses were used to conduct quasi-experimental comparisons. Results indicated that students in courses with professors who participated in the professional development self-reported 3% more behavioural and 2% more cognitive engagement than students with professors who did not participate. Within professional development group, follow-up comparisons showed that students in courses with the highest rated instructors self-reported 7% more cognitive engagement than students with lower ranked professors. Thematic coding of the qualitative data suggests that the highest rated instructors may have achieved these gains through the use of three domain general instructional strategies: activating prior knowledge, facilitating classroom interaction and promoting reflection. Findings are contextualised within extant literature reporting similar effect sizes, and implications for future engagement research from a classroom systems perspective are discussed.     

Ethics or Morals: Understanding Students’ Values Related to Genetic Tests on Humans

To make meaning of scientific knowledge in such a way that concepts and values of the life-world are not threatened is difficult for students and laymen. Ethics and morals pertaining to the use of genetic tests for hereditary diseases have been investigated and discussed by educators, anthropologists, medical doctors and philosophers giving, at least in part, diverging results. This study investigates how students explain and understand their argumentation about dilemmas concerning gene testing for the purpose to reduce hereditary diseases. Thirteen students were interviewed about their views on this issue. Qualitative analysis was done primarily by relating students’ argumentation to their movements between ethics and morals as opposing poles. Students used either objective or subjective knowledge but had difficulties to integrate them. They tried to negotiate ethic arguments using utilitarian motives and medical knowledge with sympathy or irrational and personal arguments. They discussed the embryo’s moral status to decide if it was replaceable in a social group or not. The educational implications of the students’ use of knowledge in personal arguments are discussed.     

Social engagement in a diversifying campus: a phenomenological exploration

With more non-local (Mainland China and overseas) students admitted into the universities of Hong Kong, the student population on campus is becoming much more diversified. This study was a phenomenological inquiry into the social engagement experiences of local and non-local Chinese students in their first year at a university in Hong Kong. Qualitative data was obtained from 10 focus groups. The findings suggested that the majority of the students in the study were active in social engagement and most achieved a sense of belonging to the university or its sub-communities. The culture in student communities played an important role in students' social engagement. It pushed students to become intensively involved in out-of-class activities and challenged them to reflect on the direction in which they would carry this historical legacy forward in the diversifying campus.     

Integrating Critical Approaches to Technology and Service-Learning Projects

Discussions of service learning emphasize opportunities for students to gain real world experience through work in community contexts. Less attention, however, has been given to the role of technology in these projects. Incorporating critical reflection on the rhetorical and social dimensions of technology throughout students' collaborations with clients can help to situate their practices within larger public contexts. This sort of reflection can encourage student engagement on a variety of levels: professional, rhetorical, intellectual, personal, and civic.     

Peer mentoring among doctoral students of science and engineering in Taiwan

This study describes the peer mentoring experience from doctoral student mentors?? point of view. Twelve science and engineering doctoral students participated in this phenomenology study. The findings suggest doctoral peer mentors served instrumental, psychosocial, buffering, and liaison roles; they passed on their social, professional, and academic knowledge to their mentees and tried to assist them in adapting to the culture of the lab and academia. The study identified a variety of factors that influenced their attitudes and behaviors as peer mentors and concluded this system would be beneficial to the learning and development of both individual students and lab teams. The aims of this study were threefold: first, to identify the importance and necessity of peer mentoring systems as part of the experience of working in labs in graduate school; second, to ascertain which interactions and factors in the peer mentoring relationship benefitted both peer mentors and peer mentees; and third, to explore what might constitute best practices in the peer mentoring relationship.
