Researchers and policy-makers have recognized the importance of including and promoting socioscientific argumentation in science education worldwide. The Swedish curriculum focuses more than ever on socioscientific issues (SSI) as well. However, teaching socioscientific argumentation is not an easy task for science teachers and one of the more distinguished difficulties is the assessment of students’ performance. In this study, we investigate and compare how science and Swedish language teachers, participating in an SSI-driven project, assessed students’ written argumentation about global warming. Swedish language teachers have a long history of teaching and assessing argumentation and therefore it was of interest to identify possible gaps between the two groups of teachers’ assessment practices. The results showed that the science teachers focused on students’ content knowledge within their subjects, whereas the Swedish language teachers included students’ abilities to select and use content knowledge from reliable reference resources, the structure of the argumentation and the form of language used. Since the Swedish language teachers’ assessment correlated more with previous research about quality in socioscientific argumentation, we suggest that a closer co-operation between the two groups could be beneficial in terms of enhancing the quality of assessment. Moreover, SSI teaching and learning as well as assessment of socioscientific argumentation ought to be included in teacher training programs for both pre- and in-service science teachers.  相似文献

ABSTRACT

The purpose of the investigation was to investigate the consistency of NOS views among high school students across different scientific and socio-scientific contexts. A total of 261 high school students from eight different schools in Lebanon participated in the investigation. The schools were selected based on different geographical areas in Lebanon and the principals’ consent to participate in the study. The investigation used a qualitative design to compare the responses of students across different contexts/topics. All the participants completed a five-item open-ended questionnaire, which includes five topics addressing scientific and socio-scientific contexts. The items of the questionnaire addressed the empirical, tentative, and subjective aspects of NOS. Quantitative and qualitative analyses were conducted to answer the research questions. Results showed that participants’ views of the emphasised NOS aspects were mostly inconsistent. Plus, there was variance in participants’ views of NOS between scientific and socio-scientific issues. Discussion of the results related to differential developmental progression, contextual factors, social constructivist perspective, different domains of knowledge, and students’ individual differences.  相似文献

Research exploring the possible link between quality of argumentation and content knowledge is not straightforward. Some studies suggest a positive relationship (e.g. Dawson & Schibeci in J Biol Educ 38(1):7–12, 2003) while others do not (e.g. Zohar & Nemet in J Res Sci Teach 39:35–62, 2002). This study examined the possible relationship between pre-service science teachers’ (PSTs) lines of argument regarding genetic cloning issues and their knowledge of the related content. In the research, pre-service teachers were divided into groups according to the results of a conceptual understanding test on genetic cloning, and were categorized as high, middle and low achievers. After introducing three socio-scientific scenarios (relating to genetic cloning) with the intention of prompting lines of argumentation, the PSTs then participated in semi-structured interviews with the research team. It was revealed that there is not a significant relationship between the quality of socio-scientific argumentation among PSTs and their knowledge of content in the domain of cloning. Explanations for these results are discussed in light of the related literature and with reference to the interviews.  相似文献

This paper argues the possible simultaneous development and transfer of students' argumentation skills from one socio-scientific issue to another in a Confucian classroom. In Malaysia, the Chinese vernacular schools follow a strict Confucian philosophy in the teaching and learning process. The teacher talks and the students listen. This case study explored the transfer of argumentation skills across two socio-scientific issues in such a Form 2 (8th grade) classroom. An instructional support to complement the syllabus was utilised. The teaching approach in the instructional support was more constructivist in nature and designed to introduce argumentation skills which is uncommon in a Confucian classroom. The two socio-scientific issues were genetically modified foods and deforestation. This paper presents a part of the bigger case study that was conducted. Data collected from written arguments were analysed using an analytical framework built upon Toulmin's ideas. The whole class analysis indicated progression in students' argumentation skills in their ability to give more valid grounds and rebuttals during the transfer. The individual analysis suggests progression in the majority of students' performance, while several students demonstrated non-progression when they faced a different socio-scientific issue.  相似文献

This study examines how student practice of scientific argumentation using socioscientific bioethics issues affects both teacher expectations of students’ general performance and student confidence in their own work. When teachers use bioethical issues in the classroom students can gain not only biology content knowledge but also important decision-making skills. Learning bioethics through scientific argumentation gives students opportunities to express their ideas, formulate educated opinions and value others’ viewpoints. Research has shown that science teachers’ expectations of student success and knowledge directly influence student achievement and confidence levels. Our study analyzes pre-course and post-course surveys completed by students enrolled in a university level bioethics course (n = 111) and by faculty in the College of Biology and Agriculture faculty (n = 34) based on their perceptions of student confidence. Additionally, student data were collected from classroom observations and interviews. Data analysis showed a disconnect between faculty and students perceptions of confidence for both knowledge and the use of science argumentation. Student reports of their confidence levels regarding various bioethical issues were higher than faculty reports. A further disconnect showed up between students’ preferred learning styles and the general faculty’s common teaching methods; students learned more by practicing scientific argumentation than listening to traditional lectures. Students who completed a bioethics course that included practice in scientific argumentation, significantly increased their confidence levels. This study suggests that professors’ expectations and teaching styles influence student confidence levels in both knowledge and scientific argumentation.  相似文献

This paper explores how students invoked different conceptions of ‘nature’ in eight socio-scientific group discussions about human gene therapy. The paper illustrates and discusses how the students articulated nature and to what extent they elicited science factual content in the process. While the students in this study invoked nature at key places in a variety of dialectical contexts in the discussions, these invocations were often uncritical appeals and rarely involved science factual content. Even when an argument from nature was challenged, the author of that argument would often shift the sense of nature rather than elaborate upon the argumentation. It is argued that if students were properly introduced to the evaluative character of the term ‘nature’ it would not just be conducive to the quality of their argumentation, but also invite them to foreground science factual content at key places in their discussion.  相似文献

Whereas there are some studies presenting the effects of argumentation on science knowledge development, there is still a need for research discovering the interrelationship between knowledge and argumentation. The purpose of this research was to investigate a possible relationship between students?? engagement in argumentation and their conceptual knowledge. A case study design was carried out for this research. The participants of the study were tenth graders studying in an urban all-girls school. There were 5 argumentations promoted in different contexts which were embedded through the dynamics chapter, for a 10-week period. Some of the conclusions drawn from the study are as follows: First, students?? quantity and quality of arguments improve through time as they get more involved with argumentation. Second, students?? knowledge does not improve instantly when they are involved with argumentation activities, that is, knowledge development in an argumentation process takes time. Third, students?? prior knowledge affects their participation in argumentation. Last, there are some patterns that indicate the relationship between argumentation and knowledge. However, students?? arguments and their knowledge do not develop at the same time.  相似文献

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.  相似文献

Scientific argumentation is an important learning objective in science education. It is also an effective instructional approach to constructivist science learning. The implementation of argumentation in school settings requires science teachers, who are pivotal agents of transforming classroom practices, to develop sophisticated knowledge of argumentation. However, there is a lack of understanding about science teachers’ knowledge of argumentation, especially the dialogic meaning of argumentation. In this case study, we closely examine a high school physics teacher’s argumentation-related pedagogic content knowledge (PCK) in the context of dialogic argumentation. We synthesize the teacher’s performed PCK from his argumentation practices and narrated PCK from his reflection on the argumentation practices, from which we summarize his PCK of argumentation from the perspectives of orientation, instructional strategies, students, curriculum, and assessment. Finally, we describe the teacher’s perception and adaption of argumentation in his class. We also identity the barriers to argumentation implementation in this particular case and suggest solutions to overcome these barriers.  相似文献

This study examines the relationship between students’ demographic background and their experiences with writing at school, the alignment between state and National Assessment of Educational Progress (NAEP) direct writing assessments, and students’ NAEP writing performance. The study utilizes primary data collection via content analysis of writing assessment prompts and rubrics and secondary analysis with NAEP data through hierarchical linear modeling. Results indicate students from states with writing tests more similar to the NAEP do not perform significantly better than students from states with writing tests less similar to the NAEP. Rather, student demographic characteristics, including gender, ethnicity, SES, disability status, and English learner status significantly predict NAEP writing performance, as do factors related to frequency of writing across subject areas, frequency of writing for varied purposes, frequency of writing process use, and computer use in writing. The implications of the findings for writing instruction are discussed.  相似文献

This study reports on science student perceptions of their skills (scientific knowledge, oral communication, scientific writing, quantitative skills, teamwork and ethical thinking) as they approach graduation. The focus is on which teaching activities and assessment tasks over the whole programme of study students thought utilised each of the six nominated skills. In this quantitative study involving two Australian research-intensive universities, the teaching activities identified by students as developing the broadest number of skills were laboratory classes and tutorials. Lectures were only effective for developing scientific knowledge and, to a limited extent, ethical thinking. Assessment tasks that students perceived to utilise the broadest range of skills were assignments and oral presentations. The findings of this study document the students’ perspective about their gains in skill sets, and the teaching activities and assessment tasks that require them to use and thus develop these skills. The findings provide an opportunity to evaluate the constructive alignment of skills development, teaching activities and assessment tasks from a student’s perspective. Further research is required to actually measure the skills that students gain over their whole programme of study.  相似文献

Socio-scientific issues in class have been proposed in an effort to democratise science in society. A micro-ethnographic approach has been used to explore how students elaborate arguments on a socio-scientific controversy in the context of small group discussions. Several processes of group argumentation have been identified. Students’ arguments were elaborated from scientific data, common ideas and epistemological and strategic considerations. Students’ social interactions influenced the patterns of argumentation elaborated within the group discussions. Implications of this study for the teaching of socio-scientific issues in class are discussed.  相似文献

This study investigated the effects of students’ prior science knowledge and online learning approaches (social and individual) on their learning with regard to three topics: science concepts, inquiry, and argumentation. Two science teachers and 118 students from 4 eighth-grade science classes were invited to participate in this research. Students in each class were divided into three groups according to their level of prior science knowledge; they then took either our social- or individual-based online science learning program. The results show that students in the social online argumentation group performed better in argumentation and online argumentation learning. Qualitative analysis indicated that the students’ social interactions benefited the co-construction of sound arguments and the accurate understanding of science concepts. In constructing arguments, students in the individual online argumentation group were limited to knowledge recall and self-reflection. High prior-knowledge students significantly outperformed low prior-knowledge students in all three aspects of science learning. However, the difference in inquiry and argumentation performance between low and high prior-knowledge students decreased with the progression of online learning topics.  相似文献

Argumentation is fundamental to science education, both as a prominent feature of scientific reasoning and as an effective mode of learning—a perspective reflected in contemporary frameworks and standards. The successful implementation of argumentation in school science, however, requires a paradigm shift in science assessment from the measurement of knowledge and understanding to the measurement of performance and knowledge in use. Performance tasks requiring argumentation must capture the many ways students can construct and evaluate arguments in science, yet such tasks are both expensive and resource-intensive to score. In this study we explore how machine learning text classification techniques can be applied to develop efficient, valid, and accurate constructed-response measures of students' competency with written scientific argumentation that are aligned with a validated argumentation learning progression. Data come from 933 middle school students in the San Francisco Bay Area and are based on three sets of argumentation items in three different science contexts. The findings demonstrate that we have been able to develop computer scoring models that can achieve substantial to almost perfect agreement between human-assigned and computer-predicted scores. Model performance was slightly weaker for harder items targeting higher levels of the learning progression, largely due to the linguistic complexity of these responses and the sparsity of higher-level responses in the training data set. Comparing the efficacy of different scoring approaches revealed that breaking down students' arguments into multiple components (e.g., the presence of an accurate claim or providing sufficient evidence), developing computer models for each component, and combining scores from these analytic components into a holistic score produced better results than holistic scoring approaches. However, this analytical approach was found to be differentially biased when scoring responses from English learners (EL) students as compared to responses from non-EL students on some items. Differences in the severity between human and computer scores for EL between these approaches are explored, and potential sources of bias in automated scoring are discussed.  相似文献

Abstract

Assessment rubrics intend to make criteria explicit to students. However, an understanding of assessment criteria requires tacit knowledge about which students may not be aware. The lack of such knowledge is notable in undergraduate health science students taking a compulsory course in the social sciences. This study performed a content analysis of how 1st year health sciences students interpret a SOLO assessment rubric for a sociology ‘reflection piece’ essay. The findings suggest that empiricism, standardisation and lack of tacit knowledge limit students’ ways of reasoning about the rubric. These limitations manifest in a methodical difference between students’ expectations and lecturers’ intentions of using a rubric. This difference is illustrated by the students’ need for procedural knowledge and the lecturer’s expectation of conceptual knowledge. These differences have implications for teaching, learning and assessment in health sciences undergraduate education. The findings also justify a dialogical approach to assessments through facilitating students’ epistemological development.  相似文献

The issue of mathematics underachievement among students has been an increasing international concern over the last few decades. Research suggests that academic success can be achieved by focusing on both the individual and social aspects of learning. Within the area of mathematics education, the development of metacognitive skills and the incorporation of discourse in classroom instruction has resulted in students having deeper conceptual understandings of the content and increased mathematical achievement. However, studies in this field tend to focus on the effects of these practices separately, making research that seeks to harness the potential of both quite rare. This paper reports on a study that was aimed at addressing this gap in the literature by examining the effects of writing and argumentation on achievement. Two hundred and eleven students and five teachers participated in this multimethod study that investigated the effects of three treatment conditions on mathematical achievement. These conditions were writing alone, argumentation alone, and writing and argumentation combined. Analysis of covariance revealed significant differences between the groups, and tests of the contrasts showed that students who engaged in both argumentation and writing had greater knowledge gains than students who engaged in argumentation alone or neither activity.  相似文献

In this article, we use multimodality to examine how bilingual students interact with an area task from the National Assessment of Educational Progress in task-based interviews. Using vignettes, we demonstrate how some of these students manipulate the concrete materials, and use gestures, as a primary form of structuring their explanations and making mathematical meaning. We use our results as a basis to challenge the possible deficit perspective of bilingual students’ mathematical knowledge in current assessment practices. Choosing tasks that afford multiple modes of engagement and recognizing multimodal explanations in assessment practices has the potential to move us towards a better understanding of what bilingual students know and can do mathematically.  相似文献
