In response to the need for studies that focus on learning and writing in mathematics, this study examined changes in students' probabilistic thinking and writing during an instructional program that emphasized transactional writing in a problem-solving context. Although correlations between probabilistic thinking and writing levels at the end of the study were not significant, students did make significant gains in both probability reasoning and writing. Analysis of target students' journals revealed that their writing incorporated both writing symbols and mathematical symbols. These symbols were more complementary for those students whose writing increased to the higher levels during instruction. Moreover, this growth appeared to be promoted by the teacher herself, who systematically sought verbal explanations of solutions and written interpretations of diagrams and numerical patterns.

Rhetorical studies on experimental research articles in science have focused predominantly on introductions and discussions. The contextual nature of Results sections—the empirical heart of a scientific article—remains largely unexplored, however. What is known about the content of these sections comes from prescriptive style guides, which define Results as purely expository, leaving the argumentation to other sections of the article. This study examines one eminent biochemist's publications over time and a sampling of current articles authored by other biochemists. Six rhetorical moves were identified: (a) justifications for methodological selections, (b) interpretations of experimental results, (c) evaluative comments on experimental data, (d) statements citing agreement with preestablished studies, (e) statements disclosing experimental discrepancies, and (f) statements admitting interpretive perplexities. This investigation demonstrates that biochemists explicitly argue for the validity of their experimental data by employing certain rhetorical moves. Moreover, the findings challenge the traditional lore that Results sections engage in only simple, factual reporting.

These studies investigated the degree to which prompts and topic types affect the writing performance of college freshmen. The students (N = 3,452) taking the 1989 and 1990 Manoa Writing Placement Examination (MWPE) were required to write in response to two types of topics (for a total of 6,904 essays): one in response to a reading passage and another in response to a question based on personal experience. Ten such prompt sets were used in this study. Study 1 indicated that the MWPE testing procedures were reasonably reliable and consistent across semesters but that student responses to individual prompts and prompt sets were significantly different from each other. Study 2 showed that if two topic types and a large number of prompts are involved, the differences that arise in the performance on prompts or topic types can be minimized by examining the students' mean scores and changing the pairings so that the prompt sets are more equitable in subsequent administrations.

This study examined the effects of computer network technologies on teacher-student and student-student interactions in a writing course emphasizing multiple drafts and collaboration. Two sections used traditional modes of communication (face-to-face, paper, and phone); two other sections, in addition to using traditional modes, used electronic modes (electronic mail, bulletin boards, and so on). Patterns of social interaction were measured at two times: 6 weeks into the semester and at the end of the semester. Results indicate that teachers in the networked sections interacted more with their students than did teachers in the regular sections. In addition, it was found that teachers communicated more electronically with less able students than with more able students and that less able students communicated more electronically with other students.

This study uses de Beaugrande's (1980) concept analysis system to analyze a group of children's written narratives. In addition to ascertaining the potential of this system as a means of assessing coherence, the purpose of this study was to describe how 20 third graders employed narrative concepts at the local and global levels. An analysis of a maximum of nine writing samples from each child produced in response to a weekly request to write a story revealed that (1) most children were able to establish coherence consistently at a local level, (2) children varied in their establishment of coherence across samples, (3) writing reflected degrees of coherence on a continuum from less to more coherent samples, and (4) a minority of children wrote narratives that were consistently coherent at the global level. The study also supported the value of the concept analysis system as one means of assessing coherence in written narratives.

This article discusses one student's persistence in misunderstanding her teacher's written comments on her papers, even when these comments are accompanied by other response channels that serve, in part, to clarify the written comments. It presents the idea that student and teacher each bring to the written response episode a set of information, skills, and values that may or may not be shared between them, and it is the interplay of these three elements that feeds the student's reading and processing of teacher written comments and that leads to misunderstandings. This happened even for a high-achieving student in an otherwise successful classroom. An in-depth look at one student and the classroom context in which she learns to write, focusing on her grappling with her teacher's written comments, reveals the complexity of the teaching-learning process in the high school writing class.

This study examines the relationship between two measures of individual differences in social cognition and the quality of eleventh grade students' persuasive writing. Subjects completed Crockett's Role Category Questionnaire, and wrote a persuasive letter in response to the problem, “Smoking and the School Nurse.” Letters were submitted to judges for impressionistic and attributional ratings. A content-analytic measure was applied to these 40 papers to yield a measure of the number and quality of persuasive strategies employed. Finally, the same papers were submitted to a second panel, who rated them for overall persuasiveness and appropriateness of tone. Results indicated a significant relationship between interpersonal cognitive complexity and abstractness and quality of writing, persuasiveness, appropriateness of tone, and level of persuasive strategy employed.

A group of graduate students in English and language education were given a series of instructor-designed and self-designed reading and writing tasks. They wrote formal papers in response to these tasks and kept retrospective journals describing their reading and writing strategies. The study looks at the nature of introspective accounts and the usefulness of such accounts in studies of the composing process. Several writing tasks are described and analyzed, and three brief case studies are presented. The study concludes that retrospective journal accounts are a rich source of information because they permit consideration of the complex context within which composing occurs.

At least seven types of summaries have emerged in common usage, especially during the past 250 years. They may be classified as either sequential summaries that retain the original order in which information was presented or synthesizing summaries that alter this sequence to achieve specific objectives. Each type of summary developed in response to challenges facing professions, government, business, and ordinary citizens-all of whom have sought to absorb increasing quantities of information being generated in a society that is becoming more complex. This taxonomy offers a definition and brief history for each of the seven techniques, describes the growth of corporations or other organizations that can be considered leading practitioners, and comments on the potential continuing role for each type of summary. The article also focuses on several contemporary issues that will affect future research, classroom writing instruction, and information management in modern computerized offices.
