Small-group, text-based discussions are a prominent and effective instructional practice, but the literature on the effects of different group composition methods (i.e., homogeneous vs. heterogeneous ability grouping) has been inconclusive with few direct comparisons of the two grouping methods. A yearlong classroom-based intervention was conducted to examine the ways in which group composition influenced students’ discourse and comprehension. Fourth- and fifth-grade students (N = 62) were randomly assigned to either a homogeneous or heterogeneous ability small-group discussion. All students engaged in Quality Talk, a theoretically- and empirically-supported intervention using small-group discussion to promote high-level comprehension. Multilevel modeling revealed that, on average, students displayed positive, statistically and practically significant gains in both basic and high-level comprehension performance over the course of Quality Talk. Further, our findings indicated heterogeneous ability grouping was more beneficial than homogeneous ability grouping for high-level comprehension, on average, with low-ability students struggling more in homogeneous grouping. With respect to student discourse, additional quantitative and qualitative analyses revealed group composition differences in terms of the frequency, duration, and quality of student questions and responses, as well as the types of discourse low-ability students enacted in homogeneous groups. This study expands upon the extant literature and informs future research and practice on group composition methods. 相似文献

The article reports a study in which 31 volunteered Finnish undergraduate students practiced argumentation by electronic mail (e-mail). Generally argumentation refers to grounding of stated claims. The study seeks to clarify the feasibility of e-mail study environment for practicing argumentation and compares a tutor-led seminar mode and self-directed student discussion mode, using e-mail as the study tool in both modes. The data consisted of the students' 441 e-mail messages. The content analysis of the data focused on the level and development of argumentation and counterargumentation in the messages. The results indicated that the messages' level of argumentation improved during the experiment and was higher in those messages that included counterargumentation targeted against others' standpoints. In addition, the students engaged in the student-led mode of e-mail study presented more and higher-level counterargumentation compared to the students engaged in the tutor-led mode. The results suggested that e-mail is a feasible study tool in practicing academic argumentation and that, given that this is an important aim in higher education, students' self-direction and debating should be encouraged. 相似文献

As colleges continue to expand online offerings, student participation within courses should be assessed to ensure that teachers can best implement effective, responsible lesson plans. This study examined discourse in an online classroom in order to gauge student participation by observing student-to-student and student-to-instructor exchanges within the discussion board. Classroom discourse was analyzed using Stahl’s computer supported collaborative learning methodology. Data was collected to assess development of classroom dialogue through group collaboration, and to determine whether participants were interpreting previous posts and contributing to the development of the discussion topic. This study shows that students within the online classroom were able to construct deeper meanings in classroom dialogues through thoughtful and personal contributions, thereby reaching new understandings through collaborative discussion. This study contends that through insightful planning and guided responses, instructors can manage online classroom discussions to better direct student communications in order to improve collaborative learning and knowledge construction. 相似文献

Often, mathematics teachers do not incorporate whole-class discourse of students’ various ideas and solution methods into their teaching practice. Particularly complex is the in-the-moment decision-making that is necessary to build on students’ thinking and develop their collective construction of mathematics. This study explores the decision-making patterns of five experienced Dutch mathematics teachers during their novice attempts at orchestrating whole-class discourse concerning students’ various solution methods. Our goal has been to unpack the complexity of their in-the-moment decision-making during whole-class discourse through lesson observations and stimulated recall interviews. We investigated teacher decision-making adopting a model that combines two perspectives, namely (1) we explored student-teacher interaction with regard to building on student thinking and (2) we explored how the teachers based decisions during such interaction upon their own personal conceptions and interpretation of student thinking. During these novice attempts at orchestrating whole-class discourse, the teachers created many situations for students to articulate their thinking. We found that at certain instances, teachers’ in-the-moment decision-making resulted in opportunities to build on student thinking that were not completely seized. During such instances, the teachers’ decision-making was shaped by the teachers’ own conceptions of the relevant mathematics and by teacher conceptions that centered around student understanding and mathematical goals. Our findings suggest that teachers might be supported in their novice attempts at whole-class discourse by explicit discussion of the mathematics and of their conceptions with regard to student understanding and mathematical goals.

Prosody refers to features of speech such as intonation, volume and pace. In this paper, we examine teacher–student dialogue in an English lesson at a secondary school in England, using Conversation Analysis notation to mark features of prosody. We also make connections with Goffman's theoretical concept of footing. We show that, within an episode of teacher-led plenary discourse, prosody may be used to signal shifts in footing between different kinds of pedagogic activity. We identify: (i) teacher-led IRF (Initiation–Response–Feedback) discussion; (ii) the teacher's modelling of exploratory talk; (iii) a shift to instruction-giving. If teachers are able to model the enquiring tone of exploratory talk, they may in turn encourage more thoughtful contributions from students. 相似文献

The current study examined the effects of different types of instructor comments on student engagement in an online discussion. In particular, this study examined three comment types: (1) praise-oriented comments, agreeing with students’ initial messages and recapping their ideas, (2) elaboration-encouraging comments, requesting elaboration on the initial messages, and (3) perspective-widening comments, suggesting different or thought-provoking opinions responding to the initial messages. Seventeen graduate students enrolled in an online course were recruited. A content analysis was employed to evaluate the levels of knowledge construction. Interactivity was measured by the number of posts and idea units. The findings revealed that perspective-widening comments facilitated students’ evaluation on the peer postings and brought up diverse perspectives, contributing to knowledge construction. While elaboration-encouraging comments led to high interactivity among students, praise-oriented comments had no significant effect on the frequency of interactivity. 相似文献

Electronic discussion tools can have several advantages over classroom discussion to support productive learning conversations in science. This paper describes how an electronic collaborative discussion tool called the Multimedia Forum Kiosk (MFK) enabled equitable learning opportunities in scientific discourse: generating explanations, revising ideas of others, and asking questions. Studies compared gender differences in participation between class discussion and MFK discussion, as well as examined three different formats for electronic discussion: anonymous, attributed, and attributed with authority participation. Results indicate that in all discussions, 78% of the students contributed in electronic discussion compared to only 15.3% participation in class discussion. Females participated more than males in electronic discussion, and less than males in classroom discussion. Girls report feeling less stifled when participating in an electronic medium where anonymity is an option. All electronic discussions were characterized by high levels of scientific conceptual content, elaborations, and question-asking. Students generated a repertoire of models for phenomena, asked content-focusing questions, and provided causal explanations using MFK. Implications for future research and design of electronic discussion tools are discussed. 相似文献

This study examined teacher–student discourse from a sociocultural perspective in order to ascertain the nature of effective instruction for school-age students with learning disabilities. This discussion examines one teacher's resource room instruction that was part of a larger study of teacher–student discourse. The results suggested two considerations: (1) the importance of teacher self-reflection and the implications for effective teaching and learning, and (2) differential discourse patterns across academic domains. Wood's notion of contingent teaching (1991) provided a guideline for coding teacher–student discourse. The results suggest that feedback combined with cognitive structuring contribute to effective teaching and learning. 相似文献

In asynchronous threaded discussions, messages posted near the end of the week provide less time for students to critically examine and respond to ideas presented in the messages than messages posted early in the week. This study examined how the day in which messages are posted (early, midweek and weekend) in computer-supported collaborative argumentation affect the number of responses elicited by arguments and challenges, and how its effects differ across the four types of exchanges (argument–challenge, challenge–counterchallenge, challenge–explain, challenge–evidence) that serve as indicators of critical discourse. This study found that the day of posting had a significant effect on the number of responses elicited per message, with the greatest to smallest effect on argument–challenge, challenge–counterchallenge, challenge–explain and challenge–evidence exchanges respectively. These findings highlight some of the limitations of asynchronous discussions, and suggest alternative ways to implement and design discussion environments to promote higher levels of critical discourse. 相似文献

It is often assumed in education that we have left the deficit model behind, but this paper suggests that policies and programs continue to position Indigenous students within a discourse of progress and enlightenment. Through this discourse, they are positioned between an image of what they once were as disadvantaged and what they are supposed to become in the process of studying at school and university. This paper examines some of the messages that are secretly transmitted both inside and outside the classroom when Indigenous students are constituted in discourse as behind or below and having to catch‐up to the non‐Indigenous students. It suggests other ways in which teachers could address the production of cross‐cultural relations through classroom discourses to avoid positioning Indigenous people in a deficit relation to non‐Indigenous people. 相似文献

Engaging students in class is paramount if they are to gain a deep understanding of class content. Student engagement is manifested by attention to the various components of instruction. However, there is little research at the tertiary level focusing on what aspects of instruction are related to changes in student attention during class. To address this gap, we collected multiple streams of data that provide a measure of student attention during instruction. We had students in an organic chemistry course who wear hats with a camera mounted on the brim, to provide a record of student gaze (i.e. looking at the board, notes, and friends). We also had students who use electronic pens that allowed us to record what information students transferred into their notes (pencasts). Based on our initial results, we believe the data provided by the point-of-view cameras and electronic pens hold great promise for using these technologies as viable research tools in educational settings to address various research questions. 相似文献

This study examined the effects of pre‐structuring discussion threads on group performance in computer‐supported collaborative argumentation where students labeled their messages as arguments, challenges, supporting evidence, and explanations on a threaded discussion board. In the pre‐structured group students were required to post supporting and opposing arguments to designated and separate discussion threads. In the control group no discussion threads were designated for posting supporting and opposing arguments. The mean number of challenges elicited per argument was 64% greater with pre‐structured threads (ES = +.47). No significant differences were found in the mean number of counter‐challenges, supporting evidence, and explanations posted in reply to challenges. The findings suggest that prestructured discussion threads can increase the frequency of argument→challenge exchanges needed to initiate critical discourse. 相似文献

This article introduces the framing discussion, an informal discussion of a mathematical problem that takes place at the beginning of a lesson or unit. The purpose of the framing discussion is to assess student knowledge, motivate student interest, and to serve as a basis for guiding students to more formal mathematical knowledge. The article discusses the design criteria and the discourse moves necessary to execute an effective framing discussion. 相似文献

Towards a Framework of Socio-Linguistic Analysis of Science Textbooks: The Greek Case 总被引：1，自引：0，他引：1

This study aims at presenting a grid for analysing the way the language employed in Greek school science textbooks tends to
project pedagogic messages. These messages are analysed for the different school science subjects (i.e., Physics, Chemistry,
Biology) and educational levels (i.e., primary and lower secondary level). The analysis is made using the dimensions of content
specialisation (classification) and social-pedagogic relationships (framing) promoted by the language of the school science
textbooks as well as the elaboration and abstraction of the corresponding linguistic code (formality), thus combining pedagogical
and socio-linguistic perspectives. Classification and formality are used to identify the ways science textbooks tend to position
students in relation to the interior of the corresponding specialised body of knowledge (i.e., in terms of content and code)
while framing is used to identify the ways science textbooks tend to position students as learning subjects within the school
science discourse. The results show that the kind of pedagogic messages projected by the textbooks depends mainly on the educational
level and not particularly on the specific discipline. As the educational level rises a gradual move towards more specialised
forms of scientific knowledge (mainly in terms of code) with a parallel increase in the students' autonomy in accessing the
textbook material is noticed. The implications concern the way both students and teachers approach science textbooks as well
as the roles they can undertake by internalising the textbooks' pedagogic messages and also the way science textbooks are
authored. 相似文献

While a great deal of research has studied the messages students contribute to electronic discussion forums, productive participation in online learning conversations requires more than just making posts. One important pre-condition for productive interactivity and knowledge construction is engagement with the posts contributed by others. In this study, these actions (how learners interact with the existing discussion; which posts they attend to, when, and how) are conceptualized as “online listening behaviors” and are studied in the context of a large undergraduate business course taught in a blended format. Clickstream data was collected for 96 participants from 3 week-long online discussions to solve organizational behavior challenges in groups of 10–13. Listening behaviors accounted for almost three-quarters of the time learners spent in the discussions, and cluster analysis identified three distinct patterns of behavior: (1) Superficial Listeners, Intermittent Talkers; (2) Concentrated Listeners, Integrated Talkers; and (3) Broad Listeners, Reflective Talkers. The clusters differed in the depth, breadth, temporal contiguity, and reflectivity of their listening as well as in their patterns of speaking. An illustrative case study of how the listening behaviors were enacted by one student from each cluster over time was used to deepen the characterization and interpretation of each cluster. The results indicate that online listening is a complex phenomenon and a substantial component of students’ participation in online discussions. Findings are compared to the previous work on student learning approaches and implications for practice and future research are discussed. 相似文献

There is a growing interest in using classroom response systems or clickers in science classrooms at both the university and K-12 levels. Typically, when instructors use this technology, students are asked to answer and discuss clicker questions with their peers. The existing literature on using clickers at the K-12 level has largely focused on the efficacy of clicker implementation, with few studies investigating collaboration and discourse among students. To expand on this work, we investigated the question: Does clicker use promote productive peer discussion among middle school science students? Specifically, we collected data from middle school students in a physical science course. Students were asked to answer a clicker question individually, discuss the question with their peers, answer the same question again, and then subsequently answer a new matched-pair question individually. We audio recorded the peer conversations to characterize the nature of the student discourse. To analyze these conversations, we used a grounded analysis approach and drew on literature about collaborative knowledge co-construction. The analysis of the conversations revealed that middle school students talked about science content and collaboratively discussed ideas. Furthermore, the majority of conversations, both ones that positively and negatively impacted student performance, contained evidence of collaborative knowledge co-construction. 相似文献

Structured argumentation support environments have been built and used in scientific discourse in the literature. However, to the best our knowledge, there is no research work in the literature examining whether student’s knowledge has grown during learning activities with asynchronous argumentation. In this work, an intelligent computer-supported collaborative argumentation-based learning platform that detects whether the learners address the expected discussion issues is proposed. After each learner presents an argument, a term weighting method is adopted to derive input parameters of a one-class support vector machines classifier which determines if the learners’ arguments are related to the discussion topics. Notably, a peer review mechanism is established to improve the quality of the classifier. Besides, a feedback module is used to issue feedback messages to the learners if the learners have gone off on a tangent. The experimental results revealed that the students were benefited by the proposed learning-assistance platform. 相似文献
