This study is concerned with possible differences in interaction patterns between teachers and certain groups of students: high and low achievers, and boys and girls. Detailed and comprehensive records of all verbal teacher-student interactions, both public and private, were obtained through videotaping a grade 6 class in three different settings: mathematics, language and science. While there was much consistency in the way the teacher monitored in this study interacted with the different groups, some important differences occurred in the quality and quantity of his interactions with students perceived as best and weakest, and with boys and girls in mathematics classes. 相似文献

There are considerable differences among mathematics teachers with regard to the quatlity of their way of developing mathematical knowledge in the classroom. Such differences are analysed. To develop mathematical meaning requires both a consistent presentation of the mathematical symbols and of the referential meaning of these symbols with respect to the given task. On the basis of this conception we assume that the quality of teaching will differ according to how teachers cope with the relation between these two sides of meaning. From a sample of 26 teachers, an expert teacher and a non-expert teacher were selected by means of classroom observation with scales of instructional quality variables. For each of these two teachers, two lessons introducing probability (sixth grade) are analysed. For this purpose, teacher and student contributions are coded. For the expert teacher, graphic visualizations of the development of mathematical concepts across time show soft transitions between the different aspects of mathematical meaning. These transitions are made possible by a consistent explication of the relation between formal symbols and the given mathematical task. In the case of the other teacher, explication of the relationship between the object side and the symbol side of mathematical meaning is much rarer, and there are sudden switches from one aspect of meaning to another. Further differences concern the handling of student contributions.We gratefully acknowledge the help of Wolfgang Barz, Regina Dietrich and Claudia Krüger with recording, transcribing or coding lessons.

Two studies on monitoring and assisting students at risk are presented against a contemporary perspective in higher education: that of monitoring and developing the quality of student learning. A basis for risk categorisation at an individual level is outlined, and the effects of an intervention aimed at students at risk are evaluated in two contrasting settings. At risk in the present study represents, in conceptual terms, a relatively extreme set of learning behaviours.The first study approximates an ideal set of circumstances in which an individual-level intervention for students conceptually at risk is described. The second study reflects the uncompromising reality of a large first-year service course, in which a reduced form of the same intervention was pragmatically attempted. In both interventions the emphasis was on assisting students to engage manifestations of their own self-reported, contextualised study behaviour. This was the starting point of a developmental and reflective programme in which students were not taught study skills, but were rather assisted to develop deeper contextual perceptions, metalearning awareness, and internal locus.The targeted students in these studies, and the basic nature of the intervention employed, differ considerably from those used in other intervention studies. The first study produced positive results, while the second study did not. An overall conclusion is that, while interventions of the type described can assist students to develop their learning potential, they can only do so in carefully managed circumstances that are sensitive to individual students' learning problems and the discipline-specific context in which these occur. 相似文献

This article presents examples that illustrate how teachers use childrens literature in the teaching of mathematics. The examples are related to four curriculum ideologies that have influenced mathematics education in the USA for the last 75 years. It discusses why it is relevant to help teachers understand the ideological positions that influence their use of childrens literature during mathematics instruction, summarizes the four ideological positions, and presents results of a study of how teachers ideological positions relate to their use of childrens literature in the teaching of mathematics. The study examines two research questionsCan an instructional tool be developed that will highlight for teachers the different ways in which they and others use childrens literature to teach mathematics? and Can that instructional tool stimulate teacher discussion and reflection about their own beliefs and the ideological nature of the instructional environment in which they learned (as students) and teach (as teachers)? Study results indicate that both questions can be answered in the affirmative. 相似文献

Recent developments in higher education are likely to lead to increased evaluation of teaching and courses and, in particular, increased use of student evaluation of teaching and courses by questionnaire. Most studies of the validity of such evaluations have been conducted in terms of the relationship between traditional measures of how much students learn and their ratings of teaching and courses. But there have been few if any studies of the relationship between students' rating of teaching and the quality of student learning, or in how the students approached their learning.For the evaluation of teaching and courses by questionnaire to be valid we would expect that (1) those students reporting that they adopted deeper approaches to study would rate the teaching and the course more highly than those adopting more surface strategies and, more importantly, (2) those teachers and courses which received higher mean ratings would also have, on average, students adopting deeper strategies.In the paper we report the results for eleven courses in two institutions. The results, in general, support the validity of student ratings, and suggest that courses and teaching in which students have adopted deeper strategies to learning also have higher student ratings.An earlier version of this paper was presented at the 1989 Annual Conference of the Higher Education Research and Development Society of Australia. 相似文献

We studied a group of fourth grade students identified by their classroom teachers as having above average ability in mathematics who were participating in pull-out enrichment sessions. We sought to test, using observational and microgenetic methods, hypotheses regarding students' measurement strategies that have been generated post hoc by other research teams. These above-average mathematics students did not show initial difficulties with turn commands previously reported in mixed populations. They created strategies to accurately determine the correct direction of turn and to estimate the amount of turn. They did follow a similar developmental order as students in previous work: They synthesized and integrated two schemes, turn as body movement and turn as number. Analyses extending this work revealed a process of psychological curtailment in which students gradually replace full rotations of their bodies with smaller rotations of an arm, hand, or finger.This revised version was published online in September 2005 with corrections to the Cover Date. 相似文献

This paper problematises confidence as a frequently used explanation for performance in the mathematics classroom. I report on an interview-based study of how some English Advanced level (16+) students who have chosen to study mathematics, and their teachers, speak about confidence with respect to the learning of mathematics. I outline what constitutes confident learners for these teachers and, differently, for their students and what the students feel teachers could do to improve the students confident state. I discuss the implications of this for the education of prospective teachers of mathematics. 相似文献

Results of a HyperCard method for assessing the performance of expert and novice high school chemistry students solving stoichiometric chemistry problems (balancing chemical equations) have been reported. The assessment involved the use of a HyperCard instrument (Hyperequation) developed on a Macintosh platform to administer a set of five chemistry problems, register student responses, and collect data related to student performance. The chemistry problems have been previously tested and validated in traditional (pen-paper) assessment settings by other researchers. MANOVA results indicate a significant difference between the performance of expert and novice students solving the five stoichiometric chemistry problems using the Hyperequation. The study shows promise in that a HyperCard assessment method could differentiate between the performance of experts and novices in problem solving. The implication is that HyperCard might be a suitable technology for developing performance assessment methods not only in chemistry but also in other science disciplines. 相似文献

Methods developed by Newman and Casey for analyzing errors made by children attempting verbal arithmetic problems are described, with particular emphasis being given to Newman's hierarchy of error causes. Data obtained by Newman, Casey, and Clements are presented. These show that a large proportion of errors made by children in grades 5–7 in Victoria on verbal arithmetic problems are in the Newman categories Comprehension, Transformation, Process Skills, and Carelessness. 相似文献

This paper focuses on the use of multimedia-based predict–observe–explain (POE) tasks to facilitate small group learning conversations. Although the tasks were given to pairs of students as a diagnostic tool to elicit their pre-instructional physics conceptions, they also provided a peer learning opportunity for students. The study adopted a social constructivist perspective to analyse and interpret the students conversations, focussing on students articulation and justification of their own science conceptions, clarification of and critical reflection on their partners views, and negotiation of new, shared meanings. Two senior science classes participated in this interpretive study. Data sources were mainly qualitative and included audio and video recordings of students small group discussions at the computer, interviews with selected students and their teachers, classroom observations, and student surveys. Findings indicate that the computer-based POE tasks supported students peer learning conversations, particularly during the prediction, reasoning and observation stages of the POE strategy. The increased level of student control of the POE tasks, combined with the multimedia nature of the program, initiated quality peer discussions. The findings have implications for authentic, technology-mediated learning in science. 相似文献

In this study we examined differences between online distance education and traditional classroom learning for an introductory undergraduate statistics course. Two outcome dimensions were measured: students final grades and student satisfaction with the course. Using independent samples t-tests, results indicated that there was no significant difference in grades between the online and traditional classroom contexts. However, students enrolled in the online course were significantly less satisfied with the course than the traditional classroom students on several dimensions. This finding is inconsistent with the no significant difference phenomenon, described in Russells (1999) annotated bibliography, which supports minimal outcome differences between online courses and face-to-face courses.Jessica J.

Participation, Knowledge and Beliefs: A Community Perspective on Mathematics Learning 总被引：1，自引：0，他引：1

In this paper I illustrate the use of a particular situated method of interpretation in my analysis of the data from 3-year case studies of two schools. The constraints and affordances provided by different environments are shown to be key analytical tools in understanding the ways in which students develop and make use of knowledge. Various classroom incidents are analysed, demonstrating that the particular constraints and affordances of formalised mathematics classrooms, to which students become attuned, contribute to the development of learning identities that are peculiar to the school mathematics classroom and of limited use to students in the real world. An understanding of the mathematics classroom as a particular community of practice is central to this analysis.This revised version was published online in September 2005 with corrections to the Cover Date. 相似文献

The authors suggest that the gap between common evaluation practice in teacher preparation and the consensus reform goal of high levels of student learning for all students is an impediment to reinventing teacher preparation, professional development, and the professionalization of teaching. In the context of Oregons six-year-old educational transition to a standards-based design for schools and schooling, prospective teachers in Oregon have, since 1989, been required to design, develop, and implement teacher work samples as credible evidence of their effectiveness in fostering student learning as a condition for recommendation for an initial teaching license. This article describes teacher work sample methodology and evidence for its reliability and validity in evaluating the performance of prospective teachers. In short, this article describes a methodology that responds to one critical part of the National Commission on Teaching and Americas Futures challenge to reinvent teacher education and improve student learning. 相似文献

We examined the beliefs about science teaching and learning held by elementary preservice teachers in a science methods course, comparing students who had experienced an inquiry-based physics course with those who had not. Students who had taken the physics course prior to the methods semester were better equipped to recognize and learn from inquiry and better able to apply an inquiry approach to their lesson planning. Students who were concurrently enrolled in the physics course began to revise their incoming beliefs about what it means for students to be active learners in science. The students with no experience in the inquiry-based physics course maintained their limited view that science teaching should be fun, with the teacher as teller and fun-maker. 相似文献

Many universities, recognizing the student as the main consumer of college instruction, have begun to seek his views regarding the quality of teaching. In this study the Israeli student's concept of a good teacher has been investigated. A sample of second year university students were asked to select the three most important characteristics of a good teacher from a list of fifteen.It was shown that students attached primary importance to method of instruction. Of secondary importance was the teacher's ability to spark intellectual growth. Research talents, personality, and academic status were of relatively little concern. Social science, life science, law and medical students all concurred in emphasizing the importance of the teacher's ability to communicate ideas, whereas humanities students stressed his ability to stimulate thinking.It appears that undergraduate students rate teachers by their ability to transmit knowledge rather than according to the university's criteria of research and publication.The concepts good teacher and effective instruction are used interchangeably in this article, although they are not identical. 相似文献

Previous research has indicated that there is a strong relationship between the approaches to studying adopted by individual students and their qualitative perceptions of the context in which learning takes place. This study identified students who were considered to be academically at risk and involved them in an intervention programme whose aim was to produce a qualitative change in perceptions of certain key elements of the learning context.The intervention programme consisted of five forty-five minute sessions in which the focus was on three elements of the learning context, namely, the teacher/student relationship, perceptions of textbooks and notes, and the nature and role of tests and examinations.Subsequent interviews indicated that most of the participating students had experienced a qualitative improvement in their perceptions of these contextual elements and that they perceived an attendant improvement in the quality of their learning. Quantitative analysis of the relative class positions before and after the intervention suggests that these changes were accompanied by improved performance. The implications of these findings for teaching practice in higher education are discussed. 相似文献

This report describes a study which explores, from the out-of-school student viewpoint, why students are not studying chemistry anymore. In a 2-day stay at a research institution three groups of graduating high school students from different schools, together with their chemistry teacher, were confronted hands-on with molecular modeling in industry and in university. Each of these volunteer students had agreed to write an essay on School Chemistry Vs. Chemistry in Research. These essays were evaluated together by the students, the teacher, and the researcher in a meeting at their school. The opinion of the students show that school chemistry does not convey today's chemistry in research and in industry. At the computer screen the students demonstrated their skill in performing molecular modeling experiments. Moreover, at the computer screen, chemistry was fun and easier to understand. Now we begin to see the solution: our students are also our teachers. 相似文献

This study explores the existence of structural gender differences in the learning behaviour of first-year students on entry to university, based on responses to an extended form of the Approaches to Studying Inventory. The focus is on underlying dimensions of variation, that distinguish between the manner in which male and female students recalled and reported on their most recent experience of studying Science in their final secondary school year. Such differences as emerge are only partially interperatble in terms of classic deep or strategic structures. It is argued that gender-sensitive sources of variation, as manifested, are worth of further investigation and are of potential strategic value to university departments insofar as they are able to locate difficulties that students bring with them early in their undergraduate studies. 相似文献

Instructional systems differ in the amount of structure they impose on the educational environment in which learning activities take place, e.g., mastery learning implies highly structured learning, whereas problem-based learning (PBL) claims its effectiveness just because of its freedom in learning. Yet there seems to be a lot of structure in the educational system in which PBL is embedded. In this study dimensions of structure were explored in a curriculum based on PBL. Factor analysis on student judgments unfolded three forms of structure concerning different aspects of the educational environment: content, organization, and social setting.When looking for interactions between structure and student characteristics, e.g., in research on the effectiveness of PBL, it could be important to take this distinction in structure dimensions into account. In general, ATI-research suggests interaction effects for structure. The study that is presented here explored interactions between study orientation and students' appreciation of the three structure dimensions, revealing a rather consistent pattern of differences in appreciation tendencies influenced by the orientation of the student: meaning, dependence, minimalistic, or strategic. 相似文献
