Developing Character and Values for Global Citizens: Analysis of pre-service science teachers’ moral reasoning on socioscientific issues

Character and values are the essential driving forces that serve as general guides or points of reference for individuals to support decision-making and to act responsibly about global socioscientific issues (SSIs). Based on this assumption, we investigated to what extent pre-service science teachers (PSTs) of South Korea possess character and values as global citizens; these values include ecological worldview, socioscientific accountability, and social and moral compassion. Eighteen PSTs participated in the SSI programs focusing on developing character and values through dialogical and reflective processes. SSIs were centered on the use of nuclear power generation, climate change, and embryonic stem cell research. The results indicated that PSTs showed three key elements of character and values, but failed to apply consistent moral principles on the issues and demonstrated limited global perspectives. While they tended to approach the issues with emotion and sympathy, they nonetheless failed to perceive themselves as major moral agents who are able to actively resolve large-scale societal issues. This study also suggests that the SSI programs can facilitate socioscientific reasoning to include abilities such as recognition of the complexity of SSIs, examine issues from multiple perspectives, and exhibit skepticism about information.     

A Look into Students’ Retention of Acquired Nature of Science Understandings

Having the learning and retention of science content and skills as a goal of scientific literacy, it is significant to study the issue of retention as it relates to teaching and learning about nature of science (NOS). Then, the purpose of this study was to investigate the development of NOS understandings of students, and the retention of these understandings four months after being acquired through explicit reflective instruction in relation to two contexts. Participants were 24 tenth-grade students at a private high school in a city in the Middle East. Explicit NOS instruction was addressed within a six-week unit about genetic engineering. Three NOS aspects were integrated and dispersed across the unit. A questionnaire, together with semi-structured interviews, was administered as pre-, post-, and delayed post-test to assess the retention of participants’ NOS understandings. The questionnaire had two open-ended scenarios addressing controversial socioscientific issues about genetically modified food and water fluoridation. Results showed that most students improved their naïve understandings of NOS in relation to the two contexts following the six-week unit with the explicit NOS instruction. However, these newly acquired NOS understandings were not retained by all students four months after instruction. Many of the students reverted back to their earlier naïve understandings. Conclusions about the factors facilitating the process of retention as the orientation to meaningful learning and the prolonged exposure to the domain were discussed in relation to practical implications in the classroom.     

Perceptions and Practices: Biology graduate teaching assistants’ framing of a controversial socioscientific issue

Graduate teaching assistants (GTAs) are gaining increasing responsibility for the instruction of undergraduate science students, yet little is known about their beliefs about science pedagogy or subsequent classroom practices. This study looked at six GTAs who were primary instructors in an introductory biology laboratory course. Teaching assistants taught a lesson about the potential social, health, and environmental impacts of genetically modified crops. Through classroom observations and in‐depth interviews, the researchers examined how instructors chose to frame their lessons and what GTAs perceived as important for students to know about this particular socioscientific issue (SSI). Results showed a disconnect between the relatively mature conceptualizations of effective SSI instruction that emerged during interviews and classroom practice.     

Students’ Ontological Security and Agency in Science Education—An Example from Reasoning about the Use of Gene Technology

This paper reports on a study of how students' reasoning about socioscientific issues is framed by three dynamics: societal structures, agency and how trust and security issues are handled. Examples from gene technology were used as the forum for interviews with 13 Swedish high-school students (year 11, age 17–18). A grid based on modalities from the societal structures described by Giddens was used to structure the analysis. The results illustrate how the participating students used both modalities for ‘Legitimation’ and ‘Domination’ to justify positions that accept or reject new technology. The analysis also showed how norms and knowledge can be used to justify opposing positions in relation to building trust in science and technology, or in democratic decisions expected to favour personal norms. Here, students accepted or rejected the authority of experts based on perceptions of the knowledge base that the authority was seen to be anchored in. Difficulty in discerning between material risks (reduced safety) and immaterial risks (loss of norms) was also found. These outcomes are used to draw attention to the educational challenges associated with students' using knowledge claims (Domination) to support norms (Legitimation) and how this is related to the development of a sense of agency in terms of sharing norms with experts or with laymen.     

Socioscientific issues in science education: labels, reasoning, and transfer

This paper provides a critical analysis of some of the issues raised in Simonneaux and Simonneaux’s analysis of socioscientific reasoning among a group of university level students negotiating three socioscientific issues. I first discuss the labels used to reference approaches in science education that prioritize socially relevant issues and the science related to these issues. I draw distinctions between approaches labeled science-technology-society (STS), the socioscientific issues framework, and les questions socialement vives (socially acute questions), which Simonneaux and Simonneaux introduce. Next, I discuss ways in which Simonneaux and Simonneaux’s use socioscientific reasoning as an analytic construct varies with respect to its initial conceptualization. The primary distinctions include linguistic inconsistencies and the conceptual differences these language choices confer, expansion of the construct to subsume a broader range of practices, and issues related to unit of analysis (i.e., applying socioscientific reasoning as an analytic resource for assessing individual practice vs. group patterns). Finally, the issue of transfer of socioscientific reasoning is addressed. When considering the extent to which and how students leverage experiences and practice relative to the exploration of one socioscientific issue to inform their negotiation of another, I suggest that researchers and practitioners consider the distinction between the content of arguments advanced and underlying reasoning patterns. The tension between embedding science in meaningful, specific contexts and promoting forms of scientific literacy applicable to diverse, socially-relevant issues emerges as an important point of emphasis for educators interested in the socioscientific issues (or socially acute questions) movement.

Multi‐level Assessment of Scientific Content Knowledge Gains Associated with Socioscientific Issues‐based Instruction

This study explored the impact of using a socioscientific issue (SSI) based curriculum on developing science content knowledge. Using a multi‐level assessment design, student content knowledge gains were measured before and after implementation of a three‐week unit on global warming (a prominent SSI) that explored both the relevant science content and the controversy surrounding global warming. Measures of student content knowledge were made using a standards‐aligned content knowledge exam (distal assessment) and a curriculum‐aligned exam (proximal assessment). Data were collected from 108 students enrolled from two schools. Quantitative analysis of the distal assessment indicated that student post‐test scores were statistically significantly different than their pre‐test scores (F = 15.31, p<0.001). Qualitative analyses of student responses from the proximal assessment indicated that students, on average, expressed more accurate, more detailed, and more sophisticated understandings of global warming, the greenhouse effect, and the controversy and challenges associated with these issues following the three‐week unit. Combined results from the proximal and distal assessments explored in this study offer important evidence in supporting the efficacy of using SSI as contexts for science education. In addition to a discussion of the components of an SSI‐based curriculum, this study provides support for the use of SSI as a context for learning science content.     

Re-designing Science Pedagogy: Reversing the Flight from Science

This article takes as its starting point the ongoing downturn in student interest in, and engagement with, the enabling sciences. We make a case that embedding of creative pedagogies in science education has significant potential to arrest the flight from modern science. Five propositions are explored in order to argue the case: that young people are more engaged by active tasks than with a passive consumption approach to transfer of core knowledge; that it is boredom, not rigour, that disengages them––the difference is between static and dynamic sources of knowledge; that creativity is not the antithesis of scientific rigour but the core business of scientific thinking; that we now have new understandings of creative pedagogies that make teaching strategies visible and effective; and, that these strategies can build academic, digital and social capacity simultaneously and this is the new core business of the science educator. We conclude by flagging implications for leading such pedagogical change in science faculties.     

Teaching socioscientific issues: classroom culture and students’ performances

The “Treasures in the Sea: Use and Abuse” unit that deals with authentic socioscientific issues related to the Mediterranean was developed as part of a national effort to increase scientific literacy. The unit aimed to enhance active participation of the learners and encourage higher order thinking in class by applying teaching methods that reduce the unfamiliarity felt by students. This was expected through an explicit use of a variety of teaching and assessment-for-learning methods, suitable for Science for All students. Our main goal was to examine the culture of Science for All classes in which the unit was enacted. In order to address the main learning objectives, we monitored students’ performances in tasks that required the higher order thinking skills of argumentation and value judgment, which are central constituents of decision-making processes. We show that while socioscientific issues were discussed in whole class and small group sessions, and students’ argumentation improved, there is still a long way to go in applying a thinking culture in non-science major classes. We suggest that science teachers should shift from traditional content-based and value-free approach, to a sociocultural approach that views science as a community practice and the students as active participants in decision-making processes.     

Western Australian High School Students’ Understandings about the Socioscientific Issue of Climate Change

Climate change is one of the most significant science issues facing humanity; yet, teaching students about climate change is challenging: not only is it multidisciplinary, but also it is contentious and debated in political, social and media forums. Students need to be equipped with an understanding of climate change science to be able to participate in this discourse. The purpose of this study was to examine Western Australian high school students’ understanding of climate change and the greenhouse effect, in order to identify their alternative conceptions about climate change science and provide a baseline for more effective teaching. A questionnaire designed to elicit students’ understanding and alternative conceptions was completed by 438 Year 10 students (14–15 years old). A further 20 students were interviewed. Results showed that students know different features of both climate change and the greenhouse effect, however not necessarily all of them and the relationships between. Five categories of alternative conceptions were identified. The categories were (1) the greenhouse effect and the ozone layer; (2) types of greenhouse gases; (3) types of radiation; (4) weather and climate and (5) air pollution. These findings provide science educators a basis upon which to develop strategies and curriculum resources to improve their students’ understanding and decision-making skills about the socioscientific issue, climate change.
