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

Interactive digital video provides students with control of computer visualization techniques and allows them to collect, analyze, and model two-dimensional motion data. Activities that use these techniques were developed for students to investigate the concept of frames of reference in various real-life situations. This investigation examines the effect on student learning and attitudes of using these materials in an introductory college physics course. The study measured students' computer attitudes and found improvement in students' feelings of comfort in using computers after completion of the activities. We found students' prior computer experience did not influence their perceptions of the activities. The majority of participants perceived discussion and the computer visualization techniques as being very effective in helping them learn, Students' understanding of the physics concepts were assessed and the participants' scores were compared with nonparticipants' scores. Although analysis of variance statistical procedures revealed no significant differences between the two groups, the results of this study indicate that sophisticated instructional video software can be perceived as easy to use and effective by students who are novices and experts in using computers. Thus, interactive digital video tools and activities have the potential to provide physics teachers with the latest technology to bring the active process of learning physics to their classroom. © 1997 John Wiley & Sons, Inc.

The work of Bishop and Anderson (1990) plays a major role in educators' understanding of evolution education. Their findings remind us that the majority of university students do not understand the process of evolution but that conceptual change instruction can be moderately effective in promoting the construction of a scientific understanding. The present article details two studies that represent an effort to focus on and define the limits of the Bishop and Anderson (1990) study. Study A describes a close replication of the work of Bishop and Anderson (1990) using the same conceptual-change teaching module to teach a unit on evolution to students enrolled in a biology course for nonmajors. Study B, a case of comparison, used the same evaluation instrument used in Bishop and Anderson (1990) and Study A, but high school students were the participants and the instruction was based on the inquiry approach to science. Like Bishop and Anderson (1990), Study A showed that the amount of prior instruction and students' beliefs in evolution were not found to be large factors in students' use of scientific conceptions. Unlike the original study, the students in Study A showed only a meager increase in their use of scientific conceptions for evolution. In Study B, students in the experimental group showed significant increases in their use of scientific conceptions. These findings suggest a need to investigate more closely the teachers' theories of learning, their reliance on instructional conversations, and the amount of time devoted to the topic of evolution as we study conceptual change in this area. 相似文献

Threshold concepts are transformative, integrative, and provocative; understanding these difficult concepts allows students to be capable of solving advanced problems. This investigation and evaluation of a metacognitive curricular approach explore variation in students' and teachers' discernment of structural complexity of concepts and its potential for enhancing students' learning and conceptual understanding of threshold concepts. Three trials of a metacognitive assessment activity administered to two cohorts of a civil engineering course (n?=?276 and n?=?264) were investigated. Students were presented with several answers (varying in structural complexity) to a question about a threshold concept and asked to mark each response. Quantitative analyses compared students' and teachers' marking schemes within and across trials, and qualitative analyses explored students' written reflections following the activity. Students' justifications for their marking schemes, their reflections on the activity's usefulness, and the convergence of students' and teachers' marking schemes suggest that the activity supported deep forms of student learning. 相似文献

Speech pathology students readily identify the importance of a sound understanding of anatomical structures central to their intended profession. In contrast, they often do not recognize the relevance of a broader understanding of structure and function. This study aimed to explore students' perceptions of the relevance of anatomy to speech pathology. The effect of two learning activities on students' perceptions was also evaluated. First, a written assignment required students to illustrate the relevance of anatomy to speech pathology by using an example selected from one of the four alternative structures. The second approach was the introduction of brief “scenarios” with directed questions into the practical class. The effects of these activities were assessed via two surveys designed to evaluate students' perceptions of the relevance of anatomy before and during the course experience. A focus group was conducted to clarify and extend discussion of issues arising from the survey data. The results showed that the students perceived some course material as irrelevant to speech pathology. The importance of relevance to the students' “state” motivation was well supported by the data. Although the students believed that the learning activities helped their understanding of the relevance of anatomy, some structures were considered less relevant at the end of the course. It is likely that the perceived amount of content and surface approach to learning may have prevented students from “thinking outside the box” regarding which anatomical structures are relevant to the profession.

Educational technology supports meaningful learning and enables the presentation of spatial and dynamic images, which portray relationships among complex concepts. The Technology-Enabled Active Learning (TEAL) Project at the Massachusetts Institute of Technology (MIT) involves media-rich software for simulation and visualization in freshman physics carried out in a specially redesigned classroom to facilitate group interaction. These technology-based learning materials are especially useful in electromagnetism to help students conceptualize phenomena and processes. This study analyzes the effects of the unique learning environment of the TEAL project on students' cognitive and affective outcomes. The assessment of the project included examining students' conceptual understanding before and after studying electromagnetism in a media-rich environment. We also investigated the effect of this environment on students' preferences regarding the various teaching methods. As part of the project, we developed pre- and posttests consisting of conceptual questions from standardized tests, as well as questions designed to assess the effect of visualizations and experiments. The research population consisted of 811 undergraduate students. It consisted of a small- and a large-scale experimental groups and a control group. TEAL students improved their conceptual understanding of the subject matter to a significantly higher extent than their control group peers. A majority of the students in the small-scale experiment noted that they would recommend the TEAL course to fellow students, indicating the benefits of interactivity, visualization, and hands-on experiments, which the technology helped enable. In the large-scale implementation students expressed both positive and negative attitudes in the course survey. 相似文献

In recent years, a number of curriculum reform projects have championed the notion of having students do science in ways that move beyond hands‐on work with authentic materials and methods, or developing a conceptual grasp of current theories. These reformers have argued that students should come to an understanding of science through doing the discipline and taking a high degree of agency over investigations from start to finish. This stance has occasionally been mocked by its critics as an attempt to create “little scientists”—a mission, it is implied, that is either romantic or without purpose. Here, we make the strong case for a practice‐based scientific literacy, arguing through three related empirical studies that taking the notion of “little scientists” seriously might be more productive in achieving current standards for scientific literacy than continuing to refine ideas and techniques based on the coverage of conceptual content. Study 1 is a classroom case study that illustrates how project‐based instruction can be carried out when teachers develop guidance and support strategies to bootstrap students' participation in forms of inquiry they are still in the process of mastering. Study 2 shows how sustained on‐line work with volunteer scientists appears to influence students' success in formulating credible scientific arguments in written project reports following an authentic genre. Study 3, using data from three suburban high school classes, suggests that involving students in the formulation of research questions and data analysis strategies results in better spontaneous use of empirical data collection and analysis strategies on a transfer task. The study also suggests that failing to involve students in the formulation of research can result in a loss of agency. The implications of these findings for future research and practice are discussed. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 234–266, 2004 相似文献

The authors examined the implementation of written reflections in a Grade 4 mathematics classroom over the course of 8 weeks. Students in this case study engaged in a workshop modeled after Calkin's Writers' Workshop and within this workshop the use of writing as a reflective tool in mathematics was introduced. The authors explore how students used writing to evaluate their learning and how the teacher used the students' written reflections as a formative assessment for instructional purposes. Students' written reflections were coded and these codes were used to conduct an inductive thematic analysis. Analysis of written reflections via constant-comparison analysis was used for further differentiation. The findings show students' ability to accurately self-evaluate their problem-solving skills and highlighted students' confidence level with certain mathematical concepts. Teachers were able to use students' reflections as a place to begin conferring with a student for further clarification. The written reflections aided in instructional decisions and increased individual instruction when needed. The authors include implications for teacher practice and areas for future research. 相似文献

This article focuses on the need to include ethnographic-based approaches in the writing assessments of culturally and linguistically diverse populations. The inclusion of such approaches can help teachers gain a deeper understanding of the complexities of learning for all students and realize how students' social and cultural lives mingle with the assessment process and with their academic learning. In Part 1 of the article, I describe an investigation of the assessment of students' informative essays using a single-method, holistic approach. English teachers rated essays written by eight ethnically diverse fifth- and sixth-grade students using an array of rhetorical and linguistic measures - including overall quality, coherence, sentence-level mechanics, and use of an organizational structure. Findings indicate that, within this paradigm of assessment, culturally and linguistically diverse students may be penalized for preferring rhetorical patterns that differ from the mainstream academic patterns rewarded in schools. In Part 2, I describe an investigation of the assessment of the same eight students' informal informative essays using a multifaceted approach, including ethnographic techniques and micro- and macrolevel text analyses. Findings suggest that the multifaceted approach provided a more accurate picture of the students' expository language resources. In the final section, I demonstrate how the ethnographic-based techniques provide illustrative evaluation data useful for forging a fit among the language resources and functions of writing for culturally and linguistically diverse students and their assessment and instructional needs. 相似文献

Students often hold strong attitudes regarding topics they encounter during their studies, and many instructors feel that these attitudes can have strong effects on students' performance. We characterized students' attitudes toward evolution and investigated the influence of students' attitudes (pre‐course and post‐course) regarding evolution on their performance in an evolution course, measured as their final grade. We found our students to hold positive attitudes toward evolution; these attitudes became more positive following the course. The most significant change in attitude occurred in the group of students initially undecided toward evolution. We also found that attitudes prior to the course had little influence on later achievement; however, at the end of the course, students' attitudes were positively related to final grades, although the effect was small. We argue that pedagogical techniques directly addressing students' attitudes help reduce the influence of attitudes (especially prior attitudes) on achievement. © 2005 Wiley Periodicals, Inc.

The use of computer conferencing by higher education institutions offering distance education courses has expanded rapidly since 1987. Despite a parallel growth in the academic scholarship, few studies examined students' experience of learning in an on‐line course. Using unstructured interviews and observations at adultstudents' homes or worksites, thestudy investigated adult student perspectives of distance study by computer conferencing. It found theseadults actively engaged in social relationships outside their distance studies which sustain their educational pursuits. The students provided insights into aspects of the on‐line environment: asynchronicity, interactivity, textual communications, and collaboration. Their learning orientation suggested the value they placed on conference activities. They incidentally transferred or invented learning strategies to deal with the different dynamics of this instructional environment. The computer conference brought together widely dissimilar students and encouraged them to ‘talk’ with one another, while unaware of each others' physical attributes. On‐line relationships served meaningful purposes, but rarely continued beyond the course. Based on these findings, the study presents an Adult Distance Study Through Computer Conferencing Model to guide understanding of the student experience with this medium. 相似文献

Only a few studies have focused on how teachers deal with mistakes in actual classroom settings. Teachers' error management behavior was analyzed based on data obtained from direct (Study 1) and videotaped systematic observation (Study 2), and students' self-reports. In Study 3 associations between students' and teachers' attitudes towards mistakes and their impact on students' domain specific emotions were investigated. Together, the presented studies contribute to the understanding of the interplay between teachers' everyday instructional routines surrounding mistakes and students' beliefs about (learning from) errors. The findings also emphasize the relevance of how students perceive their teachers' attitudes towards mistakes. 相似文献

Abstract. The author examined the effectiveness of training in symbolic logic for improving students' deductive reasoning. A total of 116 undergraduate students (approximately equal numbers of men and women) enrolled in 1st-year university philosophy courses in symbolic logic participated in 2 studies. In both studies, students completed booklets of categorical and conditional syllogisms at the beginning of the course and again at the end of the course. In Study 2, students also specified their reasoning strategies. Results indicated that students' strategies changed with training (students increased their use of mental models and mental rules with categorical and conditional syllogisms, respectively), but their reasoning performance improved only moderately. The educational implications of these results are explored. 相似文献

This self-study describes the development and use in a preservice literacy course of the first author's narrative of her own schooling. The introduction to that narrative is included in this paper. The full text of the narrative also describes the impact of school readiness, resource placement, transience, poverty, and teachers' responses and expectations on my school experiences and my sense of self. Methods of data collection included students' anonymous responses to the narrative, in-class discussion, students' final course papers, my research journal, field notes, and retrospective re-analysis. The perspective of a colleague who is serving as a critical friend on my journey is incorporated in the paper as dialogical insets interrogating my practices and interpretations. Writing, analyzing, and using the narrative in my teaching served to clarify my understanding of how my childhood and schooling shape my current work. Sharing it with students was built on the belief that doing so would encourage their development of understanding for students who have histories and backgrounds unlike their own. 相似文献

The instructional influence upon students' conceptions and problem-solving ability of presenting pictures at the molecular level when introducing chemistry concepts and solving chemistry problems was investigated. Before instruction, the Group Assessment of Logical Thinking (GALT) was administered and its score was used as a covariate. For the treatment group, 31 pictorial materials were used during 21 hours of Korean academic high school chemistry classes. For the control group, traditional instruction was used. Six classroom observations (1 hour each in duration) for each group were made. After instruction, the Chemistry Conceptions Test, and the Chemistry Problem-Solving Test (CPST) consisting of 10 pairs of pictorial and algorithmic problems, were administered. Korean students' success on pictorial questions from the CPST was higher than that reported in the literature for college students; however, Korean students did very poorly on algorithmic questions. The GALT score was significantly correlated with students' conceptions and problem-solving ability. Analysis of covariance results indicated that instruction with pictorial materials at the molecular level helped students construct more scientifically correct conceptions than traditional instruction. However, use of the pictorial materials had no facilitating effect on problem-solving ability. © 1997 John Wiley & Sons, Inc. J Res Sci Teach 34: 199–217, 1997. 相似文献

In this study, we developed online critiquing activities using an open-source computer learning environment. We investigated how well the activities scaffolded students to critique molecular models of chemical reactions made by scientists, peers, and a fictitious peer, and whether the activities enhanced the students' understanding of science models and chemical reactions. The activities were implemented in an eighth-grade class with 28 students in a public junior high school in southern Taiwan. The study employed mixed research methods. Data collected included pre- and post-instructional assessments, post-instructional interviews, and students' electronic written responses and oral discussions during the critiquing activities. The results indicated that these activities guided the students to produce overall quality critiques. Also, the students developed a more sophisticated understanding of chemical reactions and scientific models as a result of the intervention. Design considerations for effective model critiquing activities are discussed based on observational results, including the use of peer-generated artefacts for critiquing to promote motivation and collaboration, coupled with critiques of scientific models to enhance students' epistemological understanding of model purpose and communication. 相似文献

Classrooms are complex environments in which curriculum, students, and teachers interact. In recent years a number of studies have investigated the effect of teachers' epistemologies on the classroom environment, yet little is known about students' epistemologies and how these interact with those of teachers. The purpose of this study was to document students' epistemologies and their concurrent views about knowing and learning. Using a written essay, short-answer responses to statements, a preferred classroom environment inventory, and interviews, students' views on scientific knowledge and their own knowing and learning were collected from 42 students in three sections of an introductory physics course. Our rather broad, qualitative inquiry provides a dynamic view of students' understanding of knowing and learning in high school physics. Our analyses reveal a spectrum of epistemological commitments commensurable with positions from objectivism to relativism, most of them with experientialist coloring. Even within individuals, these commitments could be at once commensurable and incommensurable with the same epistemological position. We also find rather significant inter- and intra-individual differences with respect to the consequences of a specific epistemological stance to learning, the learning strategies employed, and the learning environment preferred. Students' views on knowing and learning in physics are presented in the form of an emergent theory. The findings are discussed in terms of their application to classroom environments. 相似文献
