The purpose of this study was to examine the effects of a year-long professional development program in classroom discussion designed to improve students' argumentation skills in language arts classes. Twenty-six fifth-grade teachers and their 471 students at two research sites participated: 14 teachers in the experimental condition, who received the professional development, and 12 teachers in the comparison condition. Results showed that the professional development led to statistically significant improvements in the quality of teachers' facilitation and student argumentation during discussions, and in students' performance on individual argumentative reading and writing tasks following the discussions, at the end of the year. Findings suggest that the professional development for teachers resulted in strengthened student abilities to connect positions with relevant reasons and evidence, and that argumentation skills acquired in the discussions may have transferred to students’ individual argumentation, at least for reading outcomes. 相似文献

Argument writing is challenging for elementary students. Previous experimental research has focused on scaffolding rhetorical goals, leaving content goals relatively unexplored. In a randomized experiment, 73 students in grades 5, 6, and 7 wrote persuasive texts about difficult-to-classify vertebrates. Each student received one of three sets of writing prompts: a persuasive goal only (control); a persuasive goal + rhetorical-subgoal prompts; or a persuasive goal + content-subgoal prompts. Rhetorical subgoals increased text quality, variety of rhetorical moves, number of complex propositions, and classification knowledge. Content subgoals increased the number of simple propositions in text. A path analysis indicated that content-subgoal prompts and rhetorical-subgoal prompts elicited different paths to writing and learning. 相似文献

We report on a study of the effect of meta-level awareness on the use of evidence in discourse. The participants were 66 pre-service teachers who were engaged in a dialogic activity. Meta-level awareness regarding the use of evidence in discourse was heightened by having same-side peers collaborating in arguing on the computer against successive pairs of peers on the opposing side of an issue on the topic of Climate Change and by engaging in explicit reflective activities on the use of evidence. Participants showed significant advances both in their skill of producing evidence-based arguments and counterarguments and regarding the accuracy of the evidence used. Advances were also observed at the meta-level, reflecting at least implicit understanding that using evidence is an important goal of argumentation. Another group of pre-service teachers, who studied about the role of evidence in science in the context of regular curriculum and served as a control condition, did not exhibit comparable advances in the use of evidence in argumentation. Educational implications are discussed. 相似文献

South African student teachers were studied to see how they coped with requirements to teach science using argumentation. Lesson observations, plans, reflective logs, post-teaching interviews and assessment of pupils’ argumentation were used to compare student teachers’ preparedness and interactions with pupils. Two clusters of students were identified representing high preparedness and low interaction. A high degree of preparedness alone did not guarantee high levels of argumentation. Schools’ educational situations were independent of success in teaching argumentation. The outcomes and implications for further development of teaching critical thinking are discussed. 相似文献

The ability to build arguments is a crucial skill and a central educational goal in all school subjects including science as it enables students to formulate reasoned opinions and thus to cope with the increasing complexity of knowledge. In the present cross-sectional study, we examined the domain-specificity of argumentative writing in science by comparing it with a rather general type of argumentation as promoted in first-language education and with formal reasoning to gain insight into different forms of argumentation on theoretical and empirical levels. Using a paper-and-pencil test, we analyzed written argumentations and the reasoning abilities of 3,274 Grade-10 students in German secondary schools. Correlation and multiple regression analyses as well as a qualitative analysis of students' answers to a subset of tasks in the domains of science and first-language education were conducted. Results showed moderate relations between argumentation in science, argumentation in first-language education, and reasoning. Half of the variance in argumentation in science was explained by individual differences in argumentation in first-language education and reasoning. Furthermore, the examination of written arguments revealed differences, for example, in students' weighing of pros and cons. We assume that the familiarity of the underlying scientific information may play an essential role in the argumentation process and posit that it needs to be investigated in more detail. Overall, the study indicates that investigating the argumentational abilities of learners in first-language education and reasoning abilities can help to shed light on the domain-specificity of argumentation in science. 相似文献

This study investigates the effects of argument stance on knowledge inquiry skills. Sixty-two participants were assigned to three argument stance conditions (proponent, opponent, or control) to receive scaffolded argumentation practice on two science issues in random order. After the argumentation treatment, participants were asked to write down their own opinions regarding the claim. Their responses were analysed according to argument structure, argument content, methods of refutation, and number of new propositions. Results revealed that taking a proponent's stance increased the use of evidence in argumentation, while taking an opponent's stance enhanced both the use of evidence and alternative-based refutations to the claim, number of falsifications, and number of new propositions. This implies that arguing from an opponent's stance may increase the search for multiple causes behind observed phenomena and the need for evidence, thereby alleviating the confirmation bias in thinking. 相似文献

Summaries English Before constructing a new curriculum for any level in integrated‐science education, it is very important to establish a basic philosophy of science teaching which reflects a symbiotic relationship between education and the socio‐economic development in a particular country of the world. The curriculum structure of integrated‐science education should broaden the basis of curricular decision and should be designated to follow the expectations of the society in providing professional intellectual training so that education can make a significant contribution to the socio‐economic growth of the country. This basic assumption which established a link between cultural and socio‐economic growth, involves a diversification of the cultural trends of science education which must become appropriate to the economic and historical context of each country in a fast changing world of work. Therefore, by critically removing outside influences in the transmission of scientific knowledge, there should be less uniformity in the context and methods of teaching, and considerable restructuring of education for each country should occur. Thus, considering the historical and geographical differences, a new order in international division of labour would come into being. In such a hypothesis, a research‐oriented integrated curriculum in science education can play a central role (certainly a better one than in the traditional, discipline‐oriented scheme of science teaching) in obtaining an adequate interaction between scientific education and social problems; this is required for modern cultural and economic development of the world. 相似文献

As reading and writing are both language processes, one can assume relationships between them, but the exact nature of these relationships has not yet been determined. While a large body of research has addressed reading comprehension and written production independently, very little investigation has examined the possible relationships between these two psycholinguistic processes, particularly from a discourse and cognitive perspective. Argumentative texts were analyzed in the present investigation on reading–writing connections. Four tests were designed and tested on 439 eighth graders. The tests assessed psycholinguistic variables that account for the microstructural, macrostructural and superstructural levels of comprehension/production processing. Correlation results showed significant coefficients between reading and writing of argumentative texts in all the psycholinguistic levels analyzed. These results suggest that the processes involved in both activities share some common knowledge-based strategies. 相似文献

This research aimed to determine the extent to which twelfth-grade chemistry textbooks and workbooks included argumentation-driven inquiry skills in their activities. For this purpose, all activities found in the twelfth grade chemistry textbooks and workbooks were analyzed using an analysis rubric. Results indicate that the inclusion of the argumentation-driven inquiry skills in the analyzed chemistry activities generally fell within argumentation-driven inquiry levels one and two. This type of inclusion favors teacher-centered learning and teaching rather than student-centered learning and teaching. Therefore, the authors recommend that these textbooks and workbooks be revised to ensure that the argumentation-driven inquiry skills that are included are directed toward student-centered learning and teaching as required by levels four and three. 相似文献

Scientific writing is related to the practice of communicating scientific knowledge. This study treats scientific writing as a social practice, taking as its premise the notion that participating in related activities such as reading, peer evaluation, and discussion would positively affect the competence of students’ scientific writing, by developing their epistemic cognition regarding scientific knowledge communication and legitimation. An empirical study was conducted with twenty-two Chinese undergraduate students to test this premise. These students were majoring in chemistry and undertook a researcher-designed intervention course (Advanced Organic Chemistry Experiment), which embodied the integrated strategy of reading, peer evaluation, and discussion on scientific writing. Based on data pertaining to those students’ performance in terms of the normativity, objectivity, and logicality of scientific writing drawn from a previous study by the current author (Deng, Kelly, & Xiao, 2019. The development of Chinese undergraduate students’ competence of scientific writing in the context of advanced organic chemistry experiment course. Chemistry Education Research and Practice, 20, 270–287), alongside data drawn from students’ written texts in reading reflections and on-line discourse related to peer evaluation and discussion, this study claimed that the tasks of reading, peer evaluation, and discussion were seen gradually to lead to the development of Chinese undergraduate students’ greater competence in scientific writing regarding the synthetic experiments of organic chemistry. 相似文献

In scientific arguments, claims must have meaning that extends beyond the immediate circumstances of an investigation. That is, claims must be generalised in some way. Therefore, teachers facilitating classroom argumentation must be prepared to support students’ efforts to construct or criticise generalised claims. However, widely used argumentation support tools, for instance, the claim-evidence-reasoning (CER) framework, tend not to address generalisation. Accordingly, teachers using these kinds of tools may not be prepared to help their students negotiate issues of generalisation in arguments. We investigated this possibility in a study of professional development activities of 18 middle school teachers using CER. We compared the teachers’ approach to generalisation when using a published version of CER to their approach when using an alternate form of CER that increased support for generalisation. In several different sessions, the teachers: (1) responded to survey questions when using CER, (2) critiqued student arguments, (3) used both CER and alternate CER to construct arguments, and (4) discussed the experience of using CER and alternate CER. When using the standard CER, the teachers did not explicitly attend to generalisation in student arguments or in their own arguments. With alternate CER, the teachers generalised their own arguments, and they acknowledged the need for generalisation in student arguments. We concluded that teachers using frameworks for supporting scientific argumentation could benefit from more explicit support for generalisation than CER provides. More broadly, we concluded that generalisation deserves increased attention as a pedagogical challenge within classroom scientific argumentation. 相似文献

This paper constitutes an attempt to explore trends, issues and challenges that emerge when three different cohorts of pre-service teachers debate contemporary issues in science education at the University of Botswana. Apart from the author's experience of teaching the course, the impetus for this study also comes from a growing interest in the contemporary literature in the need for teachers who, in the context of globalization and knowledge economy, are ‘self-reforming’ through continually addressing the key issues of their profession. Unfortunately, the current situation is such that this burden of interrogation falls heaviest on teachers, despite their lack of skills in undertaking the task. 相似文献

This study investigated the effects of a science and society intervention on elementary school students’ argumentation skills and their attitudes toward science. One hundred and eleven fifth grade students volunteered as an experimental group to join a 12-week intervention; another 107 sixth grade students volunteered to be the comparison group. All participants completed the Student Questionnaire at the beginning and end of this study. Observation and interview results were used to triangulate and consolidate the quantitative findings. The data showed that after the intervention, the quality of the experimental group students’ arguments and their attitudes toward science were significantly higher than their comparison group counterparts. In addition, the experimental group boys made significantly greater progress in the quality of their argumentation from the pretest to posttest than the girls; and low achievers made the most significant progress in their attitudes toward science and quality of argumentation. Interviews and observations indicated that their understandings of explanation and argumentation changed over the intervention. This indicated that a science and society intervention can enhance both the ability of students to develop strong arguments and their attitudes toward science. 相似文献
