This study explored the effects of arguing to learn in a socioscientific context on the fundamental and derived components of reading, writing, and science understanding as integral parts of science literacy. We adopted mixed-methods in which the 1-group pretest–posttest design with supplemental interviews and questionnaires. The pretest evaluated the dependent variables (reading and writing scores), the treatment was arguing to learn about the global climate change issue, the posttest evaluated the dependent variables, and follow-up questionnaires and interviews informed the quantitative results. An intact grade six class (N = 28) at an urban elementary school located in central Taiwan was the participants. Analyses of the pretest–posttest gain scores and correlations between these outcomes revealed significant (p < 0.05) improvements in writing and associations among reading, writing, and arguing to learn. Interpretation of the qualitative data (interview and questionnaire responses) supported that argumentation as an instructional treatment focused on fundamental literacy could play a positive role in facilitating students’ enhanced science understanding (derived literacy). 相似文献

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. 相似文献

This paper describes a qualitative study that investigated the nature of the participation structures and how the participation structures were organized by four science teachers when they constructed and communicated science content in their classrooms with computer technology. Participation structures focus on the activity structures and processes in social settings like classrooms thereby providing glimpses into the complex dynamics of teacher–students interactions, configurations, and conventions during collective meaning making and knowledge creation. Data included observations, interviews, and focus group interviews. Analysis revealed that the dominant participation structure evident within participants’ instruction with computer technology was (Teacher) initiation–(Student and Teacher) response sequences–(Teacher) evaluate participation structure. Three key events characterized the how participants organized this participation structure in their classrooms: setting the stage for interactive instruction, the joint activity, and maintaining accountability. Implications include the following: (1) teacher educators need to tap into the knowledge base that underscores science teachers’ learning to teach philosophies when computer technology is used in instruction. (2) Teacher educators need to emphasize the essential idea that learning and cognition is not situated within the computer technology but within the pedagogical practices, specifically the participation structures. (3) The pedagogical practices developed with the integration or with the use of computer technology underscored by the teachers’ own knowledge of classroom contexts and curriculum needs to be the focus for how students learn science content with computer technology instead of just focusing on how computer technology solely supports students learning of science content. 相似文献

As part of a teacher training project, 16 future chemistry teachers participated in a dramatisation activity (a mock trial of the Fritz Haber case), in which they discussed a controversy concerning an event from the history of science: the awarding of the Nobel Prize in Chemistry to Fritz Haber in 1918. Preparations for the role-play activity, the dramatisation of the mock trial, and the subsequent discussions were video-recorded. We also collected the written material produced by the pre-service teachers and the reflective journals they produced during their involvement with the activity. This article discusses the contributions of such an experience to future teachers’ knowledge on aspects related to both nature of science and argumentation, as well as to their views on their future actions related to authentic teaching of and about science. The results show that such contributions were meaningful. 相似文献

In 1991, David Macaulay was awarded the Randolph Caldecott Medal for his picturebook, Black and White (1990). He believed the Caldecott committee’s choice communicated many messages to readers of all ages: “that it is essential to see, not merely to look; that words and pictures can support each other; that it isn’t necessary to think in a straight line to make sense; and finally that risk can be rewarded” (p. 419). This article focuses on how Macaulay uses play to engage readers—to arouse their curiosity, to make them think, and to incite them to ‘see things’ in Black and White. Excerpts from Grade 5 students’ written responses illustrate some of their responses to and interpretations of various kinds of narrative and illustrative play in Black and White. 相似文献

A study is presented that explores how students’ knowledge structures, as related to the scientific method, compare at different student ages. A word association test comprised of ten total stimulus words, among them experiment, science fair, and hypothesis, is used to probe the students’ knowledge structures. Students from grades four, five, and eight, as well as first-year college students were tested to reveal their knowledge structures relating to the scientific method. Younger students were found to have a naïve view of the science process with little understanding of how science relates to the real world. However, students’ conceptions about the scientific process appear to be malleable, with science fairs a potentially strong influencer. The strength of associations between words is observed to change from grade to grade, with younger students placing science fair near the center of their knowledge structure regarding the scientific method, whereas older students conceptualize the scientific method around experiment. 相似文献

We all know that they do it, but what do students laugh about when learning science together? Although research has shown that students do use humor when they learn science, the role of humor in science education has received little attention. In this study, undergraduate students’ laughter during collaborative work in physics has been investigated. In order to do this, a framework inspired by conversation analysis has been used. Empirical data was drawn from two video-recorded sessions in which first-year engineering students solved physics problems together. The analysis revealed that the students’ use of humor was almost exclusively related to physics. Five themes identified summarize the role of humor in the group discussions: Something is obvious, Something is difficult, Something said might be wrong, Something is absurd, and Something said is not within informal norms.This study shows that humor may contribute not only to a good working atmosphere and thereby to the students’ learning but also how humor interrelates with both disciplinary culture of physics and its epistemology. The students do not only create and re-create humor that facilitates their social interactions, but through humor they constitute local norms of science and engage with the disciplinary discourse. 相似文献

The aim of this study was to examine the potential impact of the representational characteristics of models and students’ educational levels on students’ views of scientific models and modeling (VSMM). An online multimedia questionnaire was designed to address three major aspects of VSMM, namely the nature of models, the nature of modeling, and the purpose of models. The three scales of representational characteristics included modality, dimensionality, and dynamics. A total of 102 eighth graders and 87 eleventh graders were surveyed. Both quantitative data and written responses were analyzed. The influence of the representational characteristics seemed to be more salient on the nature of models and the purpose of models. Some interactions between the educational levels and the representational characteristics showed that the high school students were more likely to recognize textual representations and pictorial representations as models, while also being more likely to appreciate the differences between 2D and 3D models. However, some other differences between educational levels did not necessarily suggest that the high school students attained more sophisticated VSMM. For instance, in considering what information should be included in a model, students’ attention to particular affordances of the representation can lead to a more naive view of modeling. Implications for developing future questionnaires and for teaching modeling are suggested in this study. 相似文献

Most middle and high school students struggle with reading and writing in science. This may be because science teachers are reluctant to teach literacy in science class. New standards now require a shift in the way science teachers develop students’ literacy in science. This survey study examined the extent to which science teachers report implementing science literacy practices from the Common Core Literacy in Science and Technical Subjects and the Next Generation Science Standards with their students. A survey detailing these practices was emailed to all secondary science teachers (N = 2519) in one northeastern state and 14% of them (n = 343) responded. Practices that aligned more closely with disciplinary literacy skills and strategies were implemented more often when compared to the practices aligned with intermediate literacy skills and strategies. Since the development and intermediate skills are important to support students’ literacy progression from foundational to disciplinary, secondary science teachers may not be providing enough support for their students to be competently literate in science, in a fundamental literacy sense. This, in turn, impacts students’ ability to use fundamental literacy skills toward knowledge-building in science, achieving a derived sense of science literacy. 相似文献

This paper gives the rationale and a draft outline for a framework for education to teach epistemic insight into schools in England. The motivation to research and propose a strategy to teach and assess epistemic insight followed research that investigated how students and teachers in primary and secondary schools respond to big questions about the nature of reality and human personhood. The research revealed that there are pressures in schools that dampen students’ expressed curiosity in these types of questions and limit their developing epistemic insight into how science, religion and the wider humanities relate. These findings prompted the construction of a framework for education for students aged 5–16 designed to encourage students’ expressed interest in big questions and develop their understanding of the ways that science interacts with other ways of knowing. The centrepiece of the framework is a sequence of learning objectives for epistemic insight, organised into three categories. The categories are, firstly, the nature of science in real world contexts and multidisciplinary arenas; secondly, ways of knowing and how they interact; and thirdly, the relationships between science and religion. Our current version of the Framework is constructed to respond to the way that teaching is organised in England. The key principles and many of the activities could be adopted and tailored to work in many other countries. 相似文献

Visual representations play a critical role in enhancing science, technology, engineering, and mathematics (STEM) learning. Educational psychology research shows that adding visual representations to text can enhance students’ learning of content knowledge, compared to text-only. But should students learn with a single type of visual representation or with multiple different types of visual representations? This article addresses this question from the perspective of the representation dilemma, namely that students often learn content they do not yet understand from representations they do not yet understand. To benefit from visual representations, students therefore need representational competencies, that is, knowledge about how visual representations depict information about the content. This article reviews literature on representational competencies involved in students’ learning of content knowledge. Building on this review, this article analyzes how the number of visual representations affects the role these representational competencies play during students’ learning of content knowledge. To this end, the article compares two common scenarios: text plus a single type of visual representations (T+SV) and text plus multiple types of visual representations (T+MV). The comparison yields seven hypotheses that describe under which conditions T+MV scenarios are more effective than T+SV scenarios. Finally, the article reviews empirical evidence for each hypothesis and discusses open questions about the representation dilemma. 相似文献

Employing achievement goal theory (Ames Journal of Educational psychology, 84(3), 261–271, 1992), we explored science teachers’ instruction and its relation to students’ motivation for science learning and school culture. Based on the TARGETS framework (Patrick et al. The Elementary School Journal, 102(1), 35–58, 2001) and using data from 95 teachers, we developed a self-report survey assessing science teachers’ usage of practices that emphasize mastery goals. We then used this survey and hierarchical linear modeling (HLM) analyses to study the relations between 35 science teachers’ mastery goals in each of the TARGETS dimensions, the decline in their grade-level 5–8 students’ (N = 1.356) classroom and continuing motivation for science learning, and their schools’ mastery goal structure. The findings suggest that adolescents’ declining motivation for science learning results in part from a decreasing emphasis on mastery goals by schools and science teachers. Practices that relate to the nature of tasks and to student autonomy emerged as most strongly associated with adolescents’ motivation and its decline with age. 相似文献

In recent years, research on higher education has increasingly examined the realities of internationalisation, with a particular focus on international students’ experiences and internationalisation at home programs. These studies have explored the friendships of international students, including their relationships with both locals and internationals from other countries. However, local students’ perspectives and experiences of friendship are largely absent from this literature. The few accounts examining local students’ lives explicitly focus on improving their cross-cultural knowledge and engagement, or on rare cases of local–international student friendships. The overriding assumption in this literature is that the understandings and social practises of local students are major barriers to their relationships with internationals. This paper addresses this gap by exploring local students’ perspectives on the absence of friendships with their international peers. We utilise findings from a research project on internationalisation at home, involving interviews and focus groups with local and international students and staff at an Australian university. Focusing on locals’ discussions of potential friendships with internationals, we propose that these missing friendships are an important area of study. We find that these friendships are missing for several interrelated reasons: local–international friendships are considered unnecessary and are therefore unimagined by locals, who tend to assume that similarity and affinity naturally lead to friendships, and the structures and spaces that might facilitate friendships are absent. Ultimately, uncovering why these friendships are missing sheds fuller light on how relationships might be facilitated, potentially informing and improving universities’ internationalisation initiatives. 相似文献

The expert blind spot (EBS) hypothesis implies that even some experts with a high content knowledge might have problems in science communication because they are using the structure of the content rather than their addressee’s prerequisites as an orientation. But is that also true for students? Explaining science to peers is a crucial part of cooperative learning methods such as the “jigsaw method”. Our study examined the relationship between science communication competence (SCC) and content knowledge (CK) of 10th-grade students (N = 213). Using latent class analysis, we identified two types of students with a different relationship between CK and SCC. Using path analysis, we found that the first type of 109 students primarily used their science CK as the “resource” for addressee-oriented science communication and both their SCC and their CK were correlated with each other. For the second type of 104 students (who used other resources), their CK even had a small negative effect on their SCC. Using t tests, we found that those students primarily using their CK as the resource for communication performed significantly worse in the communication test than did those students who used other resources. Using the EBS hypothesis, we suggest that students’ CK might have ambiguous effects in communication if the content structure—rather than their addressee’s prior knowledge—is used as the primary orientation for communication. We suggest that an effective use of cooperative learning techniques in classroom requires a special prior training for their science communication skills. 相似文献

This research aimed at identifying student profiles of perceptions by means of a clustering method using a validated questionnaire. These profiles describe students’ attraction to science and technology (S&T) studies and careers as a variable driven by school S&T self-concept and interest in school S&T. In addition to three rather predictable student profiles (confident enthusiast, average ambitious, and pessimistic dropout), the fourth fairly well-populated profile called confident indifferent was produced. Our second and third research questions allowed us to describe each profile in terms of the instructional methods to which their population was exposed (including the degree to which they were actively involved) and the instructional methods to which they would like more exposure. An analysis of the evolution of the profiles’ population over time is also presented. The results suggest that pedagogical variety and active involvement in the decision to pursue S&T are important. The perception of the utility and importance of S&T both in and out of school may also play an important role in these decisions. Minor pedagogical preferences were also found in certain age groups. 相似文献

The purpose of this research is to investigate pre-university science Collège d’enseignement général et professionnel (CEGEP) students’ behavioral intentions towards using online learning technologies. Heretofore, CEGEP students’ use of technology has received scant attention, yet online learning technologies are found to play an increasingly important role in CEGEP classrooms today. The present study seeks to address this by examining CEGEP students’ use of online learning technologies. Our main research question was: What factors affect CEGEP students’ intentions to use online learning technologies? A total of 213 CEGEP students were surveyed, the resulting data was analyzed using the technology acceptance model (TAM; Davis MIS Quarterly, 13(3), 319, 1989). The findings of this research provide guidance for future implementations of online learning technologies in the CEGEP education system. 相似文献
