Investigating the Intertwinement of Knowledge,Value, and Experience of Upper Secondary Students’ Argumentation Concerning Socioscientific Issues

This study aims to explore students’ argumentation and decision-making relating to an authentic socioscientific issue (SSI)—the problem of environmental toxins in fish from the Baltic Sea. A multi-disciplinary instructional module, designed in order to develop students’ skills to argue about complex SSI, was successfully tested. Seven science majors in the final year of their upper secondary studies participated in this study. Their argumentation and decision-making processes were followed closely, and data were collected during multiple stages of the instructional module: group discussions were audio recorded, the participants wrote reports on their decision making, and postexercise interviews were conducted with individual students. The analysis focused on the skill of evaluation demonstrated by the students during the exercise and the relationships between the knowledge, values, and experiences that they used in their argumentation. Even though all of the students had access to the same information and agreed on the factual aspects of the issue, they came to different decisions. All of the students took counter-arguments and the limitations of their claims into account and were able to extend their claims where appropriate. However, their decisions differed depending on their background knowledge, values, and experiences (i.e., their intellectual baggage). The implication to SSI teaching and learning is discussed.     

Elementary Students’ Scientific Epistemological Beliefs in Relation to Socio-Economic Status and Gender

This study investigated students’ scientific epistemological beliefs in relation to socio-economic status (SES) and gender. Data were obtained from 1,152 eight grade Turkish elementary school students using Scientific Epistemological Beliefs instrument. Canonical correlation analysis indicated that students with a working mother and educated parents as well as greater number of books at home together with a separate study room are more likely to have tentative views and less likely to have fixed views about science compared to students with unemployed mother, uneducated parents, less books at home, and no separate study room. Generally, results revealed while family SES correlated positively with tentative views, it was negatively associated with fixed views, implying that students from high SES family were more likely to believe that knowledge is uncertain and not handed down by authority compared to students from low SES family. This study, however, failed to indicate any relationship between father work-status, buying daily newspaper and epistemological beliefs. In addition, Multivariate Analysis of Variance indicated that boys more likely to have tentative beliefs compared to girls.

High School Students’ Informal Reasoning Regarding a Socio‐scientific Issue,with Relation to Scientific Epistemological Beliefs and Cognitive Structures

This study investigated the relationship among 68 high school students’ scientific epistemological beliefs (SEBs), cognitive structures regarding nuclear power usage, and their informal reasoning regarding this issue. Moreover, the ability of students’ SEBs as well as their cognitive structures for predicting their informal reasoning regarding this issue was also examined. The participants’ SEBs were assessed with a quantitative instrument; their cognitive structures were assessed through tape‐recorded interviews and were further analyzed with the ‘flow map method’; their reasoning regarding nuclear power usage was assessed with an open‐ended questionnaire; and, then, their responses were analyzed both qualitatively and quantitatively. It was revealed that students’ beliefs about the justification of scientific knowledge (an aspect of the beliefs on the nature of knowing science) were significantly correlated with their reasoning quality; the extent and the richness of students’ cognitive structures as well as their usage of the information processing mode, ‘comparing,’ were positively correlated with their reasoning quality. A series of regression analyses further confirmed that students’ use of the information processing mode, ‘comparing,’ was the most significant factor for predicting reasoning quality, while their beliefs regarding the justification of scientific knowledge was the other important predictor.     

The Relationship of Science Knowledge,Attitude and Decision Making on Socio-scientific Issues: The Case Study of Students’ Debates on a Nuclear Power Plant in Korea

The purpose of this study was to investigate the relationship of students’ understanding of science knowledge, attitude and decision making on socio-scientific issues (SSI), especially on the issues of nuclear energy in Korea. SSI-focused instructions were developed to encourage students to understand and reflect on knowledge, attitude and decision making on nuclear energy in the current society. Eighty-nine students attended the instruction and participated in pre and post questionnaires to understand their understandings of nuclear energy. In this study, science knowledge was categorized into content and contextual knowledge, attitude consisted of images, safety, risk, potential, benefits and future roles, and decision making section included preference and alternative about lifetime extension of nuclear power plant. The results of questionnaires were analyzed by correlation, cross-tabulation and regression. As a result, while students’ understandings of science knowledge were significantly improved throughout the instruction, they maintained similar attitude and decision making on the issue. Regarding the relationship of the three domains, attitude showed some degree of connection to decision making whereas science knowledge did not show a significant relationship to decision making. This finding challenges SSI teaching in content-based science curriculum and classroom. Reflection and implications on the way of teaching SSI in the classroom were discussed further in this paper.     

Patterns in Students’ Argumentation Confronted with a Risk‐focused Socio‐scientific Issue

This paper reports a qualitative study on students’ informal reasoning on a controversial socio‐scientific issue. Twenty‐two students from four science classes in Norway were interviewed about the local construction of new power lines and the possible increased risk of childhood leukaemia. The focus in the study is on what arguments the students employ when asked about their decision‐making and the interplay between knowledge and personal values. Five different types of main arguments are identified: the relative risk argument, the precautionary argument, the uncertainty argument, the small risk argument, and the pros and cons argument. These arguments are presented through case studies, and crucial information and values are identified for each argument. The students made use of a range of both scientific and non‐scientific knowledge. The findings are discussed in relation to possible consequences for teaching models aimed at increasing students’ ability to make thoughtful decisions on socio‐scientific issues.     

The Effects of Different On-line Searching Activities on High School Students’ Cognitive Structures and Informal Reasoning Regarding a Socio-scientific Issue

Learners’ ability in dealing with socio-scientific issues has been highlighted in contemporary science education. This study explored the effects of different on-line searching activities on high school students’ cognitive structure outcomes and informal reasoning outcomes. By using a quasi-experimental research approach, thirty-three students were assigned to a “guided searching task group”, while thirty-five students were assigned to an “unguided searching task group”. The treatments of this study were two different on-line searching activities. All the participants were asked to search relevant information regarding nuclear power usage on the Internet during the period of two classes (100 min). However, the students in the un-guided searching task group were asked to search freely, while those in the guided searching task group were provided with a searching guideline. The participants’ cognitive structures outcomes as well as their informal reasoning outcomes regarding nuclear power usage were assessed before and after the conduct of on-line searching tasks. The results of ANCOVA revealed that the students in the guided on-line searching task group significantly outperformed their counterparts in the extent (p < 0.01) and the richness of their cognitive structures (p < 0.01). Also, they significantly outperformed their counterparts in the usage of the two information processing strategies, “comparing” (p < 0.05) and “inferring or explaining” (p < 0.05). Moreover, it was also found that the students in the guided on-line searching task group only outperformed their counterparts in their supportive argument construction (p < 0.05). In other words, the guided searching tasks did help the students obtain better cognitive structure outcomes; however, the increments on their cognitive structure outcomes may only help them to propose more supportive arguments, but their rebuttal construction (an important indicator for their reasoning quality) was not particularly improved.

Predicting Day-to-Day Changes in Students’ School-Related Affect From Daily Academic Experiences and Social Interactions

This study examined the role that everyday academic successes and failures—and the interactions with family members and peers that follow these events—play in predicting day-to-day changes in children's emotional responses to school. Middle school students (N = 101; mean age = 11.62 years) completed daily assessments of their academic experiences, performance disclosures, perceptions of emotional support, and school-related affect. Data were analyzed using hierarchical linear modeling. Results indicated that students’ daily academic experiences and social interactions varied by both sex and interaction partner, and that students’ daily academic experiences and social interactions were predictive of day-to-day changes in both positive and anxious affect. The implications of these findings for students’ interpersonal relationships and school adjustment are discussed.     

‘It’s Her Body’. When Students’ Argumentation Shows Displacement of Content in a Science Classroom

This paper approaches learning as a response instead of the acquisition of something previously expected. More specifically, it describes a process of argumentation on socioscientific issues in a classroom situation in school science amongst 15-year-old students in Sweden. The analysis of an argumentation on abortion in a science classroom highlights how science content becomes relevant to students?? experiences, but also how the students?? unique voices shift focus and cause displacement of the science content. The analysis demonstrates some of the tensions and possible conflicts that may lead to the exclusion of different voices. This paper argues that focusing the research or education on questions that argumentation brings to light creates interesting educational opportunities to identify and incorporate the students?? experiences in the classroom. The results indicate, however, that students?? spontaneous acts lead to some difficulties in finding a point of contact with the rational discourse of science education.     

Determinism and Underdetermination in Genetics: Implications for Students’ Engagement in Argumentation and Epistemic Practices

In the last two decades science studies and science education research have shifted from an interest in products (of science or of learning), to an interest in processes and practices. The focus of this paper is on students’ engagement in epistemic practices (Kelly in Teaching scientific inquiry: Recommendations for research and implementation. Sense Publishers, Rotterdam, pp 99–117, 2008), or on their practical epistemologies (Wickman in Sci Educ 88(3):325–344, 2004). In order to support these practices in genetics classrooms we need to take into account domain-specific features of the epistemology of genetics, in particular issues about determinism and underdetermination. I suggest that certain difficulties may be related to the specific nature of causality in genetics, and in particular to the correspondence between a given set of factors and a range of potential effects, rather than a single one. The paper seeks to bring together recent developments in the epistemology of biology and of genetics, on the one hand, with science education approaches about epistemic practices, on the other. The implications of these perspectives for current challenges in learning genetics are examined, focusing on students’ engagement in epistemic practices, as argumentation, understood as using evidence to evaluate knowledge claims. Engaging in argumentation in genetics classrooms is intertwined with practices such as using genetics models to build explanations, or framing genetics issues in their social context. These challenges are illustrated with studies making part of our research program in the USC.     

Graduate Social Work Students’ Experiences with Group Work in the Field and the Classroom

For decades, group work scholars have described a discrepancy between student preparation for group work practice and opportunities to work with groups in the field practicum and professional practice. Educators in related disciplines such as counseling and psychology have expressed similar concerns. This article reports findings of a study of MSW students in a program that includes a practice methods specialization in group work. The purpose was to determine the prevalence of group assignments among all students regardless of their method specialization. A majority of all respondents reported substantial opportunities to practice group work and receive appropriate supervision. Opportunities for majors in group work were significantly greater than for their non-group work counterparts. However, a majority of all students did not feel classes prepared them for group practice. Findings suggest social work must renew its commitment to preparing all students for this practice modality.     

High School Students’ Informal Reasoning on a Socio‐scientific Issue: Qualitative and quantitative analyses

Recently, the significance of learners’ informal reasoning on socio‐scientific issues has received increasing attention among science educators. To gain deeper insights into this important issue, an integrated analytic framework was developed in this study. With this framework, 71 Grade 10 students’ informal reasoning about nuclear energy usage was explored qualitatively and quantitatively. It was found that the students in this study tended to process reasoning from multiple perspectives, and most of them were prone to make evidence‐based decisions. However, less than 40% of the participants were able to construct rebuttals against counter‐arguments. It was also revealed that students’ abundant usage of supportive arguments did not guarantee for their counter‐argument construction as well as rebuttal construction, but their usage of counter‐arguments might act as precursors to their construction of rebuttals. In addition, learners’ usage of multiple reasoning modes might help them propose more arguments and, in particular, generate more counter‐arguments, which may act as precursors to their rebuttal construction. This study also showed evidence that students’ scientific knowledge that might be mainly acquired from school science instruction could be viewed as important foundation for better informal reasoning and decision‐making on socio‐scientific issues.     

Students’ communication, argumentation and knowledge in a citizens’ conference on global warming

An empirical study on 12th-grade students?? engagement on a global warming debate as a citizens?? conference is reported. Within the design-based research methodology, an interdisciplinary teaching sequence integrating an initiation to non-violent communication was developed. Students?? debates were analyzed according to three dimensions: communication, argumentation, and knowledge. Students regulated their oral contributions to the debate by identifying judgments in their discussions. Rhetorical processes developed by students were mainly related to the identity of debate protagonists with interest attributions, authority, and positions. Students?? arguments also relied on empirical data. The students?? knowledge focused on energy choices, economic, political, and science development issues. Implications for socioscientific issues integration in class are discussed.     

Teachers’ Experience of Working with Socio-scientific Issues: A Large Scale and in Depth Study

The research is an investigation of teachers’ experience of working with socio-scientific issues (SSI). A large group of teachers (55) chose one of six cases with the characteristics of SSI and were free to organize the work as they found appropriate. The research focuses on how teachers chose content, organized their work and experienced the students’ interest and learning. The teachers answered a questionnaire after working with the cases and seven of them were interviewed to provide in-depth understanding of issues raised in the questionnaire. The teachers found the SSI to be current topics with interesting content and relevant tasks and they felt confident about the work. They were quite content with the students’ learning of scientific facts, how to apply scientific knowledge and to search for information. However, they found that the students did not easily formulate questions, critically examine arguments or use media to obtain information about the task. The interviewed teachers did not find this work new, but they organized it as ‘a special event’. They understood SSI work as ‘free’ work and group work was frequent, but only a few of the teachers developed explicit strategies for teaching SSI. They had different ideas about learning but they all talked about knowledge as a set of facts to be taken in by the students. They all included elements of SSI but mostly to introduce the regular science content. However the teachers started to reflect upon the potential of using SSI to cover more goals in the curriculum.     

The Relation between Students’ Epistemological Understanding of Computer Models and their Cognitive Processing on a Modelling Task

While many researchers in science education have argued that students’ epistemological understanding of models and of modelling processes would influence their cognitive processing on a modelling task, there has been little direct evidence for such an effect. Therefore, this study aimed to investigate the relation between students’ epistemological understanding of models and modelling and their cognitive processing (i.e., deep versus surface processing) on a modelling task. Twenty‐six students, working in dyads, were observed while working on a computer‐based modelling task in the domain of physics. Students’ epistemological understanding was assessed on four dimensions (i.e., nature of models, purposes of models, process of modelling, and evaluation of models). Students’ cognitive processes were assessed based on their verbal protocols, using a coding scheme to classify their types of reasoning. The outcomes confirmed the expected positive correlation between students’ level of epistemological understanding and their deep processing (r = 0.40, p = .04), and the negative correlation between level of epistemological understanding and surface processing (r = ?0.51, p = .008). From these results, we emphasise the necessity of considering epistemological understanding in research as well as in educational practice.     

Indigenous Elementary Students’ Science Instruction in Taiwan: Indigenous Knowledge and Western Science

This preliminary ethnographic investigation focused on how Indigenous traditional wisdom can be incorporated into school science and what students learned as a result. Participants included community elders and knowledge keepers, as well as 4th grade (10-year-old) students, all of Amis ancestry, an Indigenous tribe in Taiwan. The students?? non-Indigenous teacher played a central role in developing a science module ??Measuring Time?? that combined Amis knowledge and Western science knowledge. The study identified two cultural worldview perspectives on time; for example, the place-based cyclical time held by the Amis, and the universal rectilinear time presupposed by scientists. Students?? pre-instructional fragmented concepts from both knowledge systems became more informed and refined through their engagement in ??Measuring Time??. Students?? increased interest and pride in their Amis culture were noted.
