This study investigated the impact on chemistry learning of the degree to which students embedded or integrated multiple modes of representation in end of unit writing-to-learn activities. A multi-case study approach utilizing quasi-experimental methodology involving intact high school chemistry classes taught by two different teachers was employed. Approximately half of the classes for each teacher were designated treatment classes and students in these classes participated in specific classroom activities designed to encourage the use of strategies to embed multiple modes within text in student writing. Control classes did not participate in these activities. All classes with the same teacher participated in identical end of unit writing tasks followed by identical end of unit assessments. Writing tasks and end of unit assessments were teacher designed and were therefore unique to each setting. Data from each teacher was initially analyzed independently to explore characteristics of student writing and student performance on end of unit assessments. This was followed by cross case analysis. Analysis of quantitative data indicated that for the first teacher (n = 70 students), treatment classes significantly outperformed control classes on two different measures of writing characteristics during a first unit of study, two measures of writing for the second unit, and three categories of end of unit instruction for the second unit. For the second teacher (n = 95), treatment classes outperformed control classes on two writing characteristics and three end of unit assessment categories during the only unit of study assessed. In addition, at both sites, significant positive correlations were found between all writing characteristic measurements and end of unit assessment performance. These results not only support the use of multimodal writing-to-learn tasks as a pedagogical tool to improve chemistry learning, but specifically suggest benefit when multiple modes are effectively linked within these tasks. 相似文献

This study investigates the effect of the science writing heuristic (SWH) approach on the quality of prospective science teachers’ (PSTs) argumentative writing and their understanding of the components of argumentation in the SWH approach and their own learning. Ten SWH approach activities were implemented during the semester. The study was carried out with 31 PSTs. A case study design was used. Data included the SWH approach’s grading rubric and semistructured interviews. While the ANOVA and Bonferroni tests were used to analyze the SWH approach’s grading rubric, content analysis was used to analyze the semistructured interviews conducted with 12 PSTs. The ANOVA results showed a statistical difference among the writing performance of the PSTs (F = 14.493, p < 0.01). The findings gathered from the interviews revealed that the quality of the argumentative writing and research skills of the PSTs increased over time. The PSTs made explicit associations among their beginning questions, data and observations, and claims and evidence, and they made distinctions between their data, observations, and evidence. Multiple representations played an important role in providing evidence to support claims. Moreover, the process of negotiation helped PSTs learn more effectively, and they believed that the argument-based inquiry lab was beneficial to their learning and their future vocational careers as teachers. 相似文献

Our objective was to investigate the impact of the Science Writing Heuristic (SWH) on undergraduates’ ability to express logical conclusions and include appropriate evidence in formal writing assignments. Students in three laboratory sections were randomly allocated to the SWH treatment (n?=?51 students) with another three sections serving as a control (n?=?47 students). All sections received an identical formal writing assignment to report results of laboratory activities. Four blinded raters used a 6-point rating scheme to evaluate the quality of students’ writing performance. Raters’ independent scoring agreement was evaluated using Cronbach's α. Paper scores were compared using a t-test, then papers were combined into low-scoring (3.5 of 6 points) or high-scoring (>3.5 of 6 points) sets and SWH and control cohorts were compared using Pearson's chi-square test. Papers from the SWH cohort were significantly (P?=?0.02) more likely to receive a high score than those from the control cohort. Overall scores of SWH cohort papers tended to be higher (P?=?0.07) than those from the control cohort. Gains in student conceptual understanding elicited by the SWH approach improved student ability to express logical conclusions about their data and include appropriate evidence to support those conclusions in formal research reports. Extending the writing tasks of the SWH to formal writing assignments can improve the ability of undergraduates to argue effectively for their research findings. 相似文献

This study investigated the effect of the Science Writing Heuristic (SWH) approach on grade 9 students’ understanding of chemical change and mixture concepts. Four intact classes taught by two chemistry teachers from a Turkish public high school were selected for the study; one class was assigned as the treatment group, and the other class was assigned as the comparison group. Students in the treatment group were instructed by the SWH approach, while those in the comparison group were instructed with traditionally designed chemistry instruction. Tests measuring students’ conceptual understanding in the units of chemical change and mixture were administered as pre- and posttest for both groups. At the end of the instruction, semistructured interviews were conducted with 13 students from the treatment group and eight students from the comparison group. ANCOVA results revealed that the SWH approach was superior to the traditional approach on students’ understanding of chemical change and mixture concepts. Interview results indicated that students in the treatment group demonstrated better scientific understanding of chemical change and mixture concepts compared to those in the comparison group. 相似文献

Argumentation, and the production of scientific arguments are critical elements of inquiry that are necessary for helping students become scientifically literate through engaging them in constructing and critiquing ideas. This case study employed a mixed methods research design to examine the development in 5th grade students’ practices of oral and written argumentation from one unit to another over 16 weeks utilizing the science writing heuristic approach. Data sources included five rounds of whole-class discussion focused on group presentations of arguments that occurred over eleven class periods; students’ group writings; interviews with six target students and the teacher; and the researcher’s field notes. The results revealed five salient trends in students’ development of oral and written argumentative practices over time: (1) Students came to use more critique components as they participated in more rounds of whole-class discussion focused on group presentations of arguments; (2) by challenging each other’s arguments, students came to focus on the coherence of the argument and the quality of evidence; (3) students came to use evidence to defend, support, and reject arguments; (4) the quality of students’ writing continuously improved over time; and (5) students connected oral argument skills to written argument skills as they had opportunities to revise their writing after debating and developed awareness of the usefulness of critique from peers. Given the development in oral argumentative practices and the quality of written arguments over time, this study indicates that students’ development of oral and written argumentative practices is positively related to each other. This study suggests that argumentative practices should be framed through both a social and epistemic understanding of argument-utilizing talk and writing as vehicles to create norms of these complex practices. 相似文献

ABSTRACTThis study introduced an instructional pattern that integrated the framework of the International Critical Thinking Reading and Writing Test (ICTRWT), designed by Paul and Elder, into a tertiary English as a Foreign Language (EFL) argumentative writing course. To measure the effects of the instructional pattern, a mixed methods approach was adopted. Two groups of students were involved in the experiment, with the treatment group receiving the instructional intervention and the control group receiving regular instruction in a tertiary argumentative writing course. A critical thinking test and a writing test were used to investigate the effects of the treatment, and questionnaires and interviews were also employed to examine students’ attitudes toward the instructional pattern. The quantitative statistic data reveals that students who received the instructional treatment outperformed the students in the control group in terms of overall critical thinking skills and skills of identifying and evaluating the elements of thoughts. Meanwhile, the treatment group also performed better with regard to overall writing ability, organization and coherence. Additionally, the data gained from the questionnaires and interviews suggest students’ general positive attitudes toward the instructional pattern. 相似文献

The notion of “science for all” suggests that all students—irrespective of achievement and ability—should engage in opportunities to understand the practice and discourse of science. Improving scientific literacy is an intrinsic goal of science education, yet current instructional practices may not effectively support all students, in particular, students with special needs. Argument‐based inquiry approaches, such as the Science Writing Heuristic (SWH), require all students to construct their scientific understandings by engaging in investigations and negotiating their ideas in multiple contexts, such as discussions and writing. Various SWH studies demonstrated that students engaged in appropriating the language, culture, practice, and dispositions of science generally improved their critical thinking and standardized test scores. The implementation of such an approach has several implications for science and special education research and practice, including how learning environments should be established to encourage the inclusion of all students’ ideas, as well as how scaffolded supports can and should be used to support science learning. 相似文献

Science students are increasingly challenged to use technical language related to the topics that they are studying, and therefore, science teachers benefit from knowing which tools are effective to support students in learning to use new terms. This study examined the impact of using one such tool—sentences frames—to teach science vocabulary, as measured through a science-writing task. Using an experimental approach with extant middle school science classes that offered a sample of 75 mainly Latino school students from grades six through eight, the researcher together with participating teachers identified 10 essential terms per science unit. The teachers used vocabulary-focused sentence frames for teaching the terms in one science unit, and a more traditional science text-based approach for teaching vocabulary in another unit. The writing task required at the end of the units consisted of essays in response to science-based prompts that directed students to use as many target science words as possible; matching/cloze format quizzes were also used to measure pretest and posttest receptive vocabulary knowledge. Findings indicated that there were advantages for teaching new science vocabulary via sentence frames as measured by use of the words in writing, but there were no advantages for sentence frames on quizzes measuring receptive vocabulary. Advantages of sentence frames for writing approached but did not reach statistical significance. There was some evidence that current and previous English language learners benefited more than initial English speakers from sentence frames, implying that utilizing sentence frames to teach science vocabulary might offer needed support especially for these subgroups. Limitations of the study included the sample size and the possibility that the strategy utilized in the comparison group might have offered some of the same advantages in producing language with technical vocabulary that the sentence frames unit offered. 相似文献

Current initiatives in science education in Korea have emphasized science literacy as the most important purpose of science
education; that is, science education needs to focus on helping each student to become a scientifically literate person who
is able to make reasoned decisions. In attempting to address this focus concern about science literacy, the researchers of
this study attempted to implement the Science Writing Heuristic (SWH) approach and examined both the SWH and the control groups
using the modified Reformed Teaching Observation Protocol (RTOP). Students’ performance on a Summary Writing Test (SWT) was
also examined. Participant students of this study were eighth grade students in three middle schools located in the second
biggest city in Korea. Each of the three teachers from three schools taught both the SWH and the control classes. The results
of this study showed significant differences between the SWH and the control groups on the SWT. There was a difference in
the total RTOP scores between the SWH and the control groups. Differences among schools imply that higher level of teachers’
implementation of the SWH approach would appear to result in better student achievement. 相似文献

The argumentative essay has endured as a popular form of university assessment, yet students still struggle to meet key intended learning outcomes, such as those associated with critical thinking. This paper presents the results of a study that examines the instruction provided by Australian essay writing guides to support students’ development of a questioning, critical viewpoint. Thirty publically available guides were chosen from a range of university types, and sourced from central student learning units and humanities disciplines. Findings of this documentary analysis show that some guides provide too little context for essay writing as an academic practice, and conceptualise definitional, instructional and procedural aspects of the task in ways that may not align with intended outcomes. The conclusion indicates a need for further research about the teaching of argumentative essay writing. 相似文献

This study examines how students’ opportunities to engage in argumentative activity are shaped by the teacher, the class, and the mathematical topic. It compares the argumentative activity between two classes taught by the same teacher using the same textbook and across two beginning algebra topics—investigating algebraic expressions and equivalence of algebraic expressions. The study comprises two case studies in which each teacher taught two 7th grade classes. Analysis of classroom videotapes revealed that the opportunities to engage in argumentative activity with the topic investigating algebraic expressions were similar in each teacher's two classes. By contrast, substantial differences were found between one teacher's classes with regard to the opportunities to engage in argumentative activity with the topic equivalence of algebraic expressions. The discussion highlights how the interplay between the characteristics of the mathematical topic, the characteristics of the class, and the characteristics of the teacher contributed to the shaping of students’ opportunities to engage in argumentative activity. 相似文献

This paper discusses the use of non-verbal representations in a modelling-based science teaching context, in which argumentative and explanatory situations occur. More specifically, we analyse how the students and teacher use representations in their discourse in modelling activities, and we discuss the relationships between the functions of these representations and the demands of the explanatory and argumentative situations that exist in that classroom. The data were collected by video recording all the classes in which a teaching sequence about intermolecular interactions was used—a topic which the students had not previously studied. In the activities, the students had to create, express, test, and discuss models in order to understand the difference between intermolecular and interatomic interactions, as well as their influences on the properties of substances. Initially, we selected excerpts of the recorded classes in which a non-verbal representation was used. Then, we used criteria to identify the argumentative and explanatory situations (previously defined), and we created categories for the functions of the representations that were used in order to analyse all the identified situations. The analysis supports conclusions indicating the relevance of the use of non-verbal representations in the construction, use, and defence of explanations. As the defence of explanations was the main context in which argumentative situations occurred in this study, our conclusions also indicate the contribution that representations make towards changing the status of the students' explanations. 相似文献

The authors analyze the efficacy of a cooperative method associated with self-regulated strategy development (SRSD) for argumentative writing compared with a SRSD single approach. Seven teachers and 230 ninth-grade students from three middle schools participated in the present study in which teachers were part of a practice-based professional development program. Schools were assigned either to the experimental group or to the comparison group. Over a three-month period, all students were taught SRSD strategies. After this period, students from the experimental group participated in a cooperative setting, whereas the comparison group followed the SRSD only. The results indicated that students in the experimental group made statistically significant greater gains in structural argumentative elements and in the quality of writing texts immediately after the intervention and one month later. Thus, the study provides evidence for the benefits of adding a cooperative setting to SRSD in implementing argumentative writing skills. 相似文献

The task of writing arguments requires a linguistic and cognitive sophistication that eludes many adults, but students in the US are expected to produce texts that articulate and support a claim—simple written arguments—starting in the fourth grade. Students from language-minority homes likewise must learn to produce such writing, despite their relatively limited experience with the English language, reflected in the availability of smaller mental lexicons and more restricted syntactic constructions. Yet some features of bilingual children’s cognition, such as precocious development of theory of mind and strong metalinguistic awareness, might support the crafting of arguments in writing, where the explicit consideration of multiple points of view can serve to strengthen one’s case for a claim. In this study we examine the incidence of social perspective-taking acts in the argumentative essays of language-minority and English-only students in Grades 4–6 and find that language-minority students match or surpass the English-only students on two critical measures of perspective taking (perspective acknowledgment and perspective articulation). We also explore possible links between students’ use of perspective taking in their argumentative essays and a validated formal measure of the same skill, uncovering different relationships between them in the two language groups. Links to previously attested bilingual advantages and to the development of argumentation are discussed. 相似文献

Writing is a task that entails high cognitive and linguistic efforts, especially when producing academic texts. Academic language might be one of the factors influencing the quality of written texts, given that prior research has shown its impact on reading comprehension. The purpose of this study is to examine the contribution of Spanish Core Academic Language Skills (S-CALS) and academic vocabulary to the quality of written argumentation and explanation. For this study, 126 Chilean 8th grade students produced an argumentative text and an explanatory text about the same topic. In addition, their academic vocabulary was assessed with the S-AVoc-T test and their CALS with the S-CALS-I test. Results show that both CALS and academic vocabulary are significantly and positively correlated with both writing tasks. Even though these instruments make different contributions to the predictive models in each discursive genre, a Principal Component Analysis revealed that the model that best explains writing quality are those which combine both language variables, namely Spanish Core Academic Language and Vocabulary Skills (S-CALVS). In argumentation, the S-CALVS model explains 29% of the variance, after controlling by gender. In contrast, in explanation, S-CALVS explains 35% of the variance. It is concluded that it is relevant to develop situated writing in each discursive genre and, upon that basis, to work with both CALS and academic vocabulary, because they have a specific impact on academic texts writing. 相似文献

The purpose of this study was to investigate the various roles that early elementary teachers adopt when questioning, to scaffold dialogic interaction and students’ cognitive responses for argumentative practices over time. Teacher questioning is a pivotal contributing factor that shapes the role teachers play in promoting dialogic interaction in argumentative practice and that different roles serve different functions for promoting students’ conceptual understanding. The multiple-case study was designed as a follow-up study after a 4-year professional development program that emphasized an argument-based inquiry approach. Data sources included 30 lessons focusing on whole class discussion from three early elementary teachers’ classes. Data were analyzed through two approaches: (1) constant comparative method and (2) enumerative approach. This study conceptualized four critical roles of teacher questioning—dispenser, moderator, coach, and participant—in light of the ownership of ideas and activities. The findings revealed two salient changes in teachers’ use of questions and the relationships between teachers’ question-asking and students’ cognitive responses: (1) teachers increasingly used multiple roles in establishing argumentative discourse as they persistently implemented an argument-based inquiry approach, and (2) as teachers used multiple roles in establishing patterns of questioning and framing classroom interactions, higher levels of student cognitive responses were promoted. This study suggests that an essential component of teacher professional development should include the study of the various roles that teachers can play when questioning for establishing dialogic interaction in argumentation and that this development should consist of ongoing training with systematic support. 相似文献

The attributes of a commercial microcomputer software package were evaluated as a supplement to traditional instruction in general chemistry classes in a suburban public high school. During a unit of study of writing and naming formulas and balancing chemical equations, the experimental group received reinforcement via microcomputer while the control group used parallel worksheet exercises over a period of three weeks for concept reinforcement. Analysis of achievement scores indicated significantly higher scores among the students in the control group. In order to ascertain any possible differential effects favoring either method for students at varying cognitive development levels, the study investigated the relationship between treatment (CAI versus worksheet) and development stage; no significant interactions were discovered. 相似文献
