Students’ difficulties in scientific argumentation have been widely reported in the literature. Researchers argue that these difficulties result mainly from students’ lack of understanding of the g...

Few studies, if any, have systematically investigated the connection or relationship between geography curriculum and scientific literacy. With this realization, in this article, we examined the po...

Recognising critical reasoning and problem-solving as one of the key skills for twenty-first century citizenship, various types of problem contexts have been practiced in science classrooms to enhance students’ understandings and use of evidence-based thinking and justification. Good problems need to allow students to adapt and evaluate the effectiveness of their knowledge, reasoning and problem-solving strategies. When students are engaged in complex and open-ended problem tasks, it is assumed their reasoning and problem-solving paths become complex with creativity and evidence in order to justify their conclusion and solutions. This study investigated the levels of reasoning evident in student discourse when engaging in different types of problem-solving tasks and the role of teacher interactions on students’ reasoning. Fifteen students and a classroom teacher in a Grade 5–6 classroom participated in this study. Through case analyses, the study findings suggest that (a) there was no clear co-rel...

Research shows that various stereotypes about science and science learning, such as science being filled with hard and dry content, laboratory experiments, and male-dominated work environments, hav...

Research on young children's reasoning show the complex relationships of knowledge, theories, and evidence in their decision-making and problem solving. Most of the research on children's reasoning skills has been done in individualized and formal research settings, not collective classroom environments where children often engage in learning and reasoning together to solve classroom problems. This study posits children's reasoning as a collective social activity that can occur in science classrooms. The study examined how children process their reasoning within the context of Grade 2/3 science classrooms and how the process of collectivity emerges from classroom interactions and dialogue between children as they attempt to solve their classroom problems. The study findings suggest that children's reasoning involves active evaluation of theories and evidence through collective problem solving, with consensus being developed through dialogical reasoning.

Argumentation as a form of introducing children to science has received increasing attention over the past decade. Argumentation tends to be studied and theorized through the lens of individual speakers, who contribute to a conversation by means of opposing statements. M.M. Bakhtin and L.S. Vygotsky independently proposed a very different approach by suggesting that dialogical relations inherently and irreducibly embody argumentation. From this position, dialogical relations allow children to individualize argumentation. In this study, we show how the dialogical framework provides a very different, collective perspective on children’s argumentation in problem-solving processes in elementary science classrooms.

Previous studies have shown that there is what has been called a ‘gap’ between environmental knowledge and a willingness to act in a pro-environmental manner. For the individual, this gap is probably the result of the huge complexity of factors that affect behaviour. The way in which this ‘gap’ is sometimes identified in the literature, however, is also partly a function of the fact that much of the research in this area has compared environmental attitudes in general with a willingness to take actions that are specific. In the present study, we have circumvented this latter issue by exploring links between a declared willingness to undertake specific actions and the level of belief in the efficacy of those particular actions in reducing global warming. Here we report findings on actions concerning personal transport. Because the questionnaire was designed to provide quantitative measures, novel indices could be constructed that indicate, for example, the extent to which persuading people that an action i...

This study explored and documented students' responses to opportunities for collective knowledge building and collaboration in a problem-solving process within complex environmental challenges and pressing issues with various dimensions of knowledge and skills. Middle-school students (n = 16; age 14) and high-school students (n = 16; age 17) from two Singapore public institutions participated in an environmental science field study to experience knowledge integration and a decision-making process. Students worked on six research topics to understand the characteristics of an organic farm and plan for building an ecological village. Students collected and analysed data from the field and shared their findings. Their field work and discussions were video-recorded, and their reflective notes and final reports were collected for data coding and interpretation. The results revealed that throughout the study, students experienced the needs and development of integrated knowledge, encountered the challenges of k...

A new primary science syllabus with strong inquiry focus has been implemented in Singapore since 2008. In this study, we attempted to understand how teachers experience the emphasis of inquiry-based curriculum under the current educational conditions that is routined and highly teacher fronted. We invited 50 pre-service and 41 in-service teachers to participate in survey questionnaires and narratives, reflective writings, and group discussions related to science inquiry which formed our data corpus. Data analysis in the form of thematic coding was carried out using NVivo8, with over 80% inter-rater coding agreement level. Three key aspects of teachers’ perceptions of science inquiry were revealed: (1) teachers’ responsibilities as facilitators, (2) privileging content knowledge rather than process skills, and (3) pressure of assessment systems in current educational contexts. These understandings bring out conflicts of inquiry teaching between teacher- and student-centredness, content and process, and cur...

With science and technology playing profound roles in mediating human relationships with the environment, a key question concerns which expectations and views of science and technology have emerged and prevail in visions of the social and environmental development of contemporary societies. This study engages this question through examining children’s views of science and technology in South Korea. Eighty‐six sixth graders from Seoul, a highly urbanized city, were invited to share their views. A drawing and writing activity and an open‐ended questionnaire were administered for data collection. The study found that the children’s views are grounded in optimistic and positive expectations and visions of science and technology even as some of the children show awareness and concern about environmental destruction. They may also offer contradictory views toward social development and environmental destruction. The paper discusses these findings in light of the complex meanings of development in modern Korean ...

Mobile advertising has become a new form of marketingcommunications in recent years as mobile phones became ubiquitous in many countries. While the consumer aspect of mobile advertising has attracted much attention, few studies have touched on the business aspect of this new advertising medium. The present paper explores the status and trends of mobile advertising through in-depth personalinterviews with the advertising practitioners in one of the leading mobileeconomies in the world, South Korea. Specifically, it addresses the current practices of mobile advertising, the business structure of mobile advertising market, and how mobile advertising is evaluated by practitioners.

To alleviate teachers’ reluctance toward practical work, there has been much discussion on teachers’ pedagogical content knowledge, teaching materials, and failsafe strategies for practical work. Despite these efforts, practical work is still regarded as a challenging task for many elementary science teachers. To understand the complexity of teachers’ conflicts in practical work, this study examines teachers’ ideas about teaching and learning that influence teachers’ decision‐making and action on teaching practical work. More important than knowing technical–rational aspects of practical work is to understand the internal contradictions that teachers have to resolve within themselves regarding their capabilities and beliefs about science teaching and practical work. Using stories and experiences of 38 third‐year university students in a science method course in Korea, we seek to understand the conflicts and negotiations that they experience as they make decisions regarding practical work throughout their ...

Pedagogical theories often posit the source of conceptual development in the literacy of an individual child or teacher and therefore suggest instructional strategies or instructional models based on (frequently unquestioned) presuppositions about the learning process. These theories give little attention to the real conditions that make the (real-time) communication of an idea possible in the first place. In this study, we extend the Vygotskian approach to literacy and word-meaning to give the body a central role in conceptual development. We exemplify the claims that: (a) the body constitutes the mediating hub that translates, in an ongoing manner, the experience of the world (objects) and the word in communication; and (b) the body constitutes the mediating hub that generates a new meaning unit of the word. We conclude that a body-centered framework helps understand the labour that increases the embodied resources for translating the sound-word-meaning.

In the goal of science teacher education, the role of reflection to cultivate the teacher as a transformative practitioner has been largely recognised. Reflective thinking is crucial for teachers to be mindfully and knowledgeably situated in teaching and transforming their actions. This study looks into the dilemmas of teaching practical work in elementary science classes and the roles of reflective thinking. Five preservice teachers, one inservice teacher, and one science teacher educator participated in the process of collaborative reflection (reflective writing on dilemma cases, sharing, and discussing) of teaching practical work during the preservice teachers’ practicum. All participants wrote and shared two cases of his/her own dilemmas after teaching or observing lessons with science experiments. Preservice teachers also participated in a survey questionnaire and interviews to share their perspectives of practical work and the process of reflection. Looking into their reflection and discussion on th...
