This study utilized discourse-based instruction as an alternative method of instruction that emphasizes the teaching of mathematics by actively engaging students in mathematical discourse practices. A quasi-experimental study was employed to determine the effectiveness of mathematical discourse-based instruction in enhancing eleventh-grade students’ conceptual and procedural understanding of probability and statistics. A researcher-constructed test instrument was used for data collection from the experimental and control groups. The data analysis performed using the Kruskal-Wallis test showed that the experimental group outperformed the control groups in terms of conceptual and procedural knowledge. Furthermore, the results suggest that discourse-based instruction when appropriately designed and implemented can increase students’ understanding of mathematical topics. 相似文献

It is considered important for students to participate in scientific practices to develop a deeper understanding of scientific ideas. Supporting students, however, in knowing and understanding the natural world in connection with generating and evaluating scientific evidence and explanations is not easy. In addition, writing in science can help students to understand such connections as they communicate what they know and how they know it. Although tools such as vee-maps can scaffold students?? efforts to design investigations, we know less about how these tools support students in connecting scientific ideas with the evidence they are generating, how these connections develop over time, or how writing can be used to encourage such connections. In this study, we explored students?? developing ability to reason scientifically by examining the relationship between students?? understanding of scientific phenomena and their understanding of how to generate and evaluate evidence for their ideas in writing. Three high school classes completed three investigations. One class used vee-mapping each time, one used vee-mapping once, and one did not use vee-mapping. Students?? maps and written reports were rated for understanding of relevant science procedural and conceptual ideas. Comparisons between groups and over time indicate a positive relationship between improved procedural and conceptual understanding. Findings also indicate that improved procedural understanding preceded improved conceptual understanding, and thus, multiple experiences were needed for students to connect evidence and explanation for science phenomena. 相似文献

We examine preservice mathematics teachers' conceptions of writing as a tool for learning mathematics before and after participation in and reflection on writing tasks. We describe the use of two targeted activities incorporated into a secondary methods course: writing to learn mathematics (WTLM) and reflection on that writing. Prior to participation in these activities, the preservice teachers expressed reluctance toward the use of writing in mathematics and uncertainty as to how writing could be useful in mathematics, while accepting that some possible benefits might exist for students' procedural learning. Following participation in these activities, the preservice teachers expressed a willingness to accept writing as a useful tool for supporting an expanded view of teaching and learning mathematics. Specifically, the preservice teachers considered writing as a way to build connections between mathematics and other subjects, a means to assess student understanding of mathematics, and a beneficial support for student conceptual learning. 相似文献

This study was focused on elementary school students'processes of scientific understanding within aclassroom environment characterized as a community ofdiscourse. In particular, it explored the role ofwritten discourse both on the plane of knowledgedevelopment and the conceptualization and evaluationof the writing activity itself. The purposes of thestudy were: (a) to see whether students could use writingas a means to express and compare ideas, reason andreflect on them in the process of scientificunderstanding; (b) to see whether writing in the serviceof learning facilitated the understanding of the newtopic through conceptual change; (c) to see whetherwriting affected the conceptualization of the writingactivity itself. Thirty-six fourth graders divided intwo groups, experimental (writing) and control(no-writing), were involved in the implementation ofcurriculum units on plants, whose target concept wasphotosynthesis. The findings show that in theexperimental group the students reached a betterconceptual understanding of the target concept andmore advanced metaconceptual awareness of the changesin their own knowledge structures. Moreover, theconceptualization of the writing activity seemed tochange as well to some extent as writing in aconceptual change process affected the ways learnersviewed some functions of it. 相似文献

Children benefit in many ways from actively engaging in high quality children's literature, and picture books provide a natural
avenue to motivate and encourage students' writing. Shared book experiences in small or large group settings can lead to meaningful
writing discussions and applications. Picture books serve as exemplars of the six qualities of effective writing (ideas, organization,
voice, word choice, sentence fluency, and conventions) and provide a scaffold for students to incorporate these writing attributes
in their original compositions. When primary students' writing is inspired by high-quality picture books and shared with peers,
children benefit academically and socially. 相似文献

AbstractThe purpose of this study is to examine how fifth grade students were impacted by the infusion of multiple writing tasks in mathematics. In this study, writing tasks provided opportunities for students to communicate prior knowledge, share ideas to construct and justify arguments, for reflection, and assessment. In this deductive qualitative study, students’ work samples were analyzed. Findings indicated that students grew in their understanding of mathematics and ability to self-reflect and self-evaluate through multiple opportunities to write for a variety of purposes. The opportunities for constructing mathematical understanding with activities that included writing and discourse also fostered learning between peers. The findings suggest a variety of opportunities to write and engage in mathematics discourse encouraged reflection, evaluation, and learning. Implications for future research include the need to examine the impact of these activities on students’ mathematics understanding as measured by assessments or an analysis of student work samples. 相似文献

This study, conducted in an inner-city middle school, followed the conceptual changes shown in 25 students' writing over a 12-week science unit. Conceptual changes for 6 target students are reported. Student understanding was assessed regarding the nature of matter and physical change by paper-and-pencil pretest and posttest. The 6 target students were interviewed about the goal concepts before and after instruction. Students' writing during lesson activities provided qualitative data about their understandings of the goal concepts across the science unit. The researcher constructed concept maps from students' written statements and compared the maps across time to assess changes in the schema of core concepts, complexity, and organization as a result of instruction. Target students' changes were studied in detail to determine patterns of conceptual change. After patterns were located in target students' maps, the remaining 19 students' maps were analyzed for similar patterns. The ideas that students identified in their writing showed changes in central concepts, complexity, and organization as the lessons progressed. When instructional events were analyzed in relation to students' demonstrated ideas, understanding of the goal conceptions appeared in students' writing more often when students had opportunities to explain their new ideas orally and in writing. 相似文献

The research interest underpinning this paper concerns the type of mathematical knowledge engineering students may acquire during their specialised education in terms of the conceptual and procedural dimensions of doing and using mathematics. This study draws on interviews with 25 qualified engineers from South Africa and Sweden regarding their views on the role of mathematics in engineering education, with special focus on the conceptual and procedural aspects of mathematical knowledge. A thematic analysis of the interview data led to the identification of two main themes. According to the conceptual view a predominantly conceptual approach is needed and valued more than procedural skills, while the balanced view emphasises a balance of conceptual understanding and procedural fluency as well as links between them. It is suggested that the mathematical education of engineers would need to be more conceptually oriented to prepare for the demands at the workplace. 相似文献

Writing to learn is a pedagogical approach grounded in the belief that the reasoning required to write about a topic or concept will help students gain understanding. However, research indicates that the impact writing has on student learning depends on context. Using a mixed-method, quasi-experimental, repeated measures design, we examined how embedding writing-to-learn pedagogy in a required college course impacted students’ learning as well as their perceptions of writing to learn. Our quantitative analysis revealed that writing to learn did not have a differential effect on student achievement of course goals. However, qualitative analysis revealed evidence indicating students valued writing to learn as a way to make sense of course content by reasoning through their ideas and responses to class experiences. From the instructor's perspective, writing to learn also helped build rapport with students. Our results indicated that in our context, writing to learn pedagogy had benefits and limitations. We offer practical implications and pedagogical suggestions based on our experiences and findings. 相似文献

This article discusses revisions to personal narrative writing made by Year 7 students (aged 11–12) in a UK secondary school. The concept of strategic revision was used as a basis for analysing drafts and revised texts in order to investigate strategies and techniques deployed by students in the process of revision and how these related to expectations student writers had of their readers. These analyses suggest that, given a reasonably supportive instructional environment, some Year 7 students can revise their own written texts strategically, and that in doing so they may recruit, and perhaps acquire, a range of writing skills and associated procedural knowledge. They also suggest that in the process of revising their texts, some student writers may have altered their expectations of their readers' understanding, ability to interpret and willingness to empathise. Implications for researching writing processes and for the writing curriculum are suggested, including the use of students' revisions to tap into the complex sets of procedural knowledge which seem to underlie aspects of writing and writing development. 相似文献

This study researched the use of writing-to-learn strategies within a high-school (Year 11) chemistry classroom. The writing
task itself asked the students to write a business letter to a younger audience of middle-school (Year 7) students. A mixed-method
design was used for the study, incorporating pre/post- testing with semi-structured interviews. The evidence supports that
the treatment students performed statistically significantly better on a conceptual question compared to the control group.
Additionally, the treatment students felt that writing to a younger audience prompted them to use different language than
they would have if, for example, writing to their teacher. Further, the treatment students described that the writing task
promoted their understanding of and their confidence in their knowledge of the stoichiometry concepts addressed in class. 相似文献

This article argues, in the context of national concern about standards in writing, for a reconceptualisation of the teaching of writing that acknowledges both the significance of the writer's voice and the need to teach about how written texts create meaning. The teaching of writing requires the dual activities of creating and crafting: young writers need opportunities to express their ideas and support in developing understanding of how best to shape those ideas. 相似文献

Recent research suggests that the examination of students' work may lead to changes in teaching practice that are more effective in terms of students' mathematical learning. However, the link between the examination of students' work and the teachers' actions in the classroom is largely unexamined, particularly at the secondary level. In this paper, I present the results of a study in which teachers had extensive opportunities to examine the development of students' conceptual models of exponential growth in the context of their own classrooms. I describe two related aspects of the practice of one teacher: (a) how she listened to students' alternative solution strategies and (b) how she responded to these strategies in her practice. The results of the analysis suggest that as the teacher listened to her students, she developed a sophisticated schema for understanding the diversity of student thinking. The actions of the teacher supported extensive student engagement with the task and led the students to revise and refine their own mathematical thinking. This latter action reflects a significant shift in classroom practice from the role of the teacher as evaluator of student ideas to the role of students as self-evaluators of their emerging ideas. 相似文献

The theoretical background and different methods ofconcept mapping for use in teaching and in research on learning processes are discussed. Two mathematical projects, one on fractions and one on geometry, are presented in more detail. In the first one special characteristics of concept maps were elaborated. In the second one concept mapping allowed students' individual understanding to be monitored over time and provided information about students' conceptual understanding that would not have been obtained using other methods. Regarding the students' individual concept maps in more detail there were some additional findings: (i) The characteristics of the maps change remarkably from fourth grade to sixth grade; (ii) There is some evidence that prior knowledge related to some mathematical topics plays a very important role in students' learning behaviour and in their achievement; (iii) Concept maps provide information about how individual students relate concepts to form organised conceptual frameworks; (iv) Long-term difficulties with specific concepts are able to be traced. These findings are discussed with regard to results of other studies as well as to their implications for the teaching of mathematics in the classroom. 相似文献

长期的个性箝制，窒息了学生的母语感悟和文学才情。学生从作文的虚伪滑向做人的虚伪．从“统一说话”滑向“双重人格”。作文教学要从本质上厘清“人”与“文”的关系，使“人”融入“文”，“文”又高扬着“人”；要培养学生的悟性、灵性和人格，真正建构以人为本，“人”、“文”合壁的作文机制。 相似文献

One important feature of vocational education is to provide students with solid conceptual knowledge along with substantial practical experience, acquired in school and workplace contexts, respectively. However, the research provided evidence that students do not spontaneously articulate the knowledge acquired in different contexts, and that specific instructional activities have to be designed and introduced. The present study deals with this type of activity conducted in a vocational school for health and social care assistants, which involved the use of collaborative writing about workplace critical incidents. The goal was to identify the patterns of interactions, and specifically the type of peer-feedback that engage students in productive collaboration. Qualitative analyses show that the writing productions could be categorized in four collaboration patterns differing in the level in which students would elaborate on their peers’ experience and profit from the peers’ suggestions in order to improve their understanding. On this basis, we propose a series of recommendations for implementing effective and instructionally relevant collaborative writing activities in vocational education. 相似文献

数学理解包括三种基本形态,即:记忆性理解、解释性理解和探究性理解,这三种数学理解分别对应着“记得、晓得和明得”三种不同的状态。三种数学理解对数学学习都是有价值的,但仅有记忆性和解释性理解是不够的,探究性理解才是数学教学的最终目标。实践中,不少水平不高的教师常常只能让学生达到记忆性理解,有一定水平的教师能让学生达到解释性理解,真正让学生达到探究性理解的教师并不是很多。教师要不失时机地促进学生数学理解层级的迭代升级,促使学生最终达到探究性理解,吴文俊院士数学学习的经验对把握数学理解的三种基本形态有借鉴和启迪意义。在课堂教学中引导学生从事生动活泼的数学探索性活动常常是一个相当艰难的过程,对教师的数学探究素质提出了较高的要求,教师应努力引导学生去探求数学知识的意义和发现的过程,促使学生数学探究性理解方式的养成。 相似文献
