A proof is a connected sequence of assertions that includes a set of accepted statements, forms of reasoning and modes of representing arguments. Assuming reasoning to be central to proving and aiming to develop knowledge about how teacher actions may promote students’ mathematical reasoning, we conduct design research where whole-class mathematical discussions triggered by exploratory tasks play a key role. We take mathematical reasoning as making justified inferences and we consider generalizing and justifying central reasoning processes. Regarding teacher actions, we consider inviting, informing/suggesting, supporting/guiding and challenging actions can be identified in whole-class discussions. This paper presents design principles for an intervention geared to tackle such reasoning processes and focuses on a whole-class discussion on a grade 7 lesson about linear equations and functions. Data analysis concerns teacher actions in relation to design principles and to the sought mathematical reasoning processes. The conclusions highlight teacher actions that lead students to generalize and justify. Generalizations may arise from a central challenging action or from several guiding actions. Regarding justifications, a main challenging action seems to be essential, while follow-up guiding actions may promote a further development of this reasoning process. Thus, this paper provides a set of design principles and a characterization of teacher actions which enhance students’ mathematical reasoning processes such as generalization and justification.  相似文献

Background: In research on design-based learning (DBL), inadequate attention is paid to the role the teacher plays in supervising students in gathering and applying knowledge to design artifacts, systems, and innovative solutions in higher education.

Purpose: In this study, we examine whether teacher actions we previously identified in the DBL literature as important in facilitating learning processes and student supervision are present in current DBL engineering practices.

Sample: The sample (N=16) consisted of teachers and supervisors in two engineering study programs at a university of technology: mechanical and electrical engineering. We selected randomly teachers from freshman and second-year bachelor DBL projects responsible for student supervision and assessment.

Design and method: Interviews with teachers, and interviews and observations of supervisors were used to examine how supervision and facilitation actions are applied according to the DBL framework.

Results: Major findings indicate that formulating questions is the most common practice seen in facilitating learning in open-ended engineering design environments. Furthermore, other DBL actions we expected to see based upon the literature were seldom observed in the coaching practices within these two programs.

Conclusions: Professionalization of teachers in supervising students need to include methods to scaffold learning by supporting students in reflecting and in providing formative feedback.  相似文献

Research and design activities are often employed in STEM (Science, Technology, Engineering & Mathematics) education. This study aims to examine students’ attitudes towards doing research and design activities in secondary school, among two groups of students: (1) students that take the quite recently introduced Dutch subject O&O (research & design), in which students perform authentic research and design projects related to STEM disciplines; and (2) students that do not take O&O. The subject O&O is only taught at a limited number of certified, so called ‘Technasium’, schools. A questionnaire, developed by the authors, was completed by 1625 students from Grades 8 and 11. Unlike previous studies on student attitudes, which usually use abstract concepts like ‘science’ or ‘technology’, the questionnaire used in this study contains active verbs to characterise research and design activities. The results showed that, in general, students who took the subject O&O had more positive attitudes towards doing research and design activities than regular students. Both student groups appeared to find doing design activities more enjoyable than doing research activities. The results of this study provide useful information for teachers as well as teacher educators about the existing attitudes of students, for example their preference for design projects over research projects.  相似文献

A problem identified in the literature around task design is the persistence of a gap between teacher intention and student activity. We show how principles designed around the making of distinctions and having an explicit language of mathematical thinking can eliminate the “gap” by guiding teacher planning, teacher actions in the classroom and student activity in the classroom. We show how our task design principles have developed during the time of our collaboration, over a period of 20 years, across several research projects. We argue for the importance, in task design, of an explicit theory of change and an explicit image of mathematical thinking, where the theory of change is applicable to researchers, teachers and students.  相似文献

The self-fulfilling prophecy model of Brophy and Good was applied to the area of teacher judgement in order to disclose the processes of how teacher judgement of student achievement influences students’ future academic outcomes. It was assumed that achievement and achievement motivation might be affected through the mediating processes of student-perceived positive and negative teacher treatment, which represents students’ perceptions of teachers’ actions towards them. A sample of 294 Chinese fifth-grade students and their eleven English language teachers were tracked over one school year. Structural equation modelling showed that after controlling for prior achievement and achievement motivation, teacher judgement was directly related to students’ future achievement, expectancy for success and level of aspiration. These relations were partially mediated by perceived negative teacher treatment. Teacher judgement was related to students’ academic self-concept and pride in English learning, and fully mediated by both perceived positive and negative teacher treatment. The study supported the model of Brophy and Good and identified the specific processes of how teacher judgements can become self-fulfilled. Positive and negative teacher treatment had different mediating effects. Compared with positive teacher treatment, perceived negative treatment was related to student academic outcomes more extensively.  相似文献

The basic unit of school based mathematics teaching is the lesson. This article is a contribution to understanding teacher actions that facilitate successful lessons, defined as those that engage all students, especially those who may sometimes feel alienated from mathematics and schooling, in productive and successful mathematical thinking and learning. An underlying assumption is that lessons can seek to build a sense in the students that their experience has elements in common with the rest of the class and that this can be done through attention to particular aspects of the mathematical and socio-mathematical goals. We examine three teacher actions that address the mathematical goals: using open-ended tasks, preparing prompts to support students experiencing difficulty, and posing extension tasks to students who finish the set tasks quickly; as well as actions that address the socio-mathematical goals by making classroom processes explicit. To illustrate and elaborate these actions, we describe a particular lesson taught to a heterogeneous upper primary (age 11–12) class.  相似文献

Inclusion of deaf children in regular classrooms is often described as unsuccessful. The present article shows how communicative and metacommunicative strategies used in teacher(s)-deaf students(s) interactions may facilitate inclusion. A fourth-grade classroom was investigated where a coteaching approach--a master teacher working with a teacher trained in Brazilian Sign Language (BSL)--was used. The class, 7 deaf and 19 hearing students, was selected because of the teacher dyad's effectiveness with these students. The teachers' interactive styles and strategies are highlighted, along with communicative and metacommunicative processes that occurred between them and the deaf students. The authors show that meanings are co-constructed not only through words or BSL but through nonverbal actions. Relational metacommunicative strategies make integration more effective and learning easier and more pleasant; therefore, dialogue with deaf children entails more than the mere use of words, either vocally or with signs.  相似文献

This article describes how preservice teachers accomplish and write up action research projects as part of their teacher preparation at one university in the United States. The paper is divided into four major sections. In the first section, the instructor describes how teacher research is introduced to teacher education students and how they are guided through the processes of conceptualizing, doing, and writing up their projects. The next two sections are the stories of two 1st-year teachers who describe and reflect on what they learned from completing action research projects under the direction of the instructor. The concluding section offers generalizations that synthesize lessons learned by the authors.  相似文献

Case studies of the teacher labor market in the United States reveal that “first wave” teacher reforms of the 1980s will have little positive impact on the career choices of teachers and former teachers as well on the talented college students whom policymakers wish to attract to teaching. While “second wave” reforms offer much promise in solving present teacher quality problems, these reforms may go for naught if policymakers ignore the anachronistic teacher selection processes presently used by public schools. New policies not only must address the motivations and actions of labor market decisionmakers, but also must address the underlying tension between the first and second waves of teacher reform.  相似文献

Science/Technology/Society (STS) as a reform effort has been active in Iowa for three decades. A program called Iowa Chautauqua has evolved over the four decades to promote K-12 STS teaching in Iowa’s 300 school districts. This is a study of how teachers have become Teacher Leaders of the reforms and lead other teachers who enroll as new teachers and schools each New Year. All were involved with Action Research projects each year while also assisting graduate student teams who serve as research associates. In this study, students were asked to identify specific teacher actions that were designed to make student learning more successful. The study examines general student views of teacher actions as well as specific examples of how students interact with the teacher and how the teachers encourage greater student/student involvement. The results show success with STS and how it defines science and affective actions of teachers in classrooms. Student views of Teacher Leaders, new Chautauqua teachers, and Control Teachers with no STS or Chautauqua experiences provide ways of recognizing successes of current reform efforts.  相似文献

Computer-Supported Collaborative Learning (CSCL) can be a powerful tool in creating learning communities in which students have a chance to construct knowledge collaboratively and to develop explanations of the subject to be studied. It is obvious, however, that collaborative inquiry is a cognitively-challenging task for an individual student. More evidence on the nature and quality of students' actions and strategic processes in CSCL is needed to make these models more applicable in different domains of classroom learning. The aim of this study was to analyse students' strategic actions in Computer-Supported Collaborative Learning. Eighteen secondary school students, ages 13–14 years, participated in CSCL inquiries in their literature class. The networked technology environment used was CSILE. The students had three inquiry-based CSCL projects, each lasting for six weeks. The data-collection procedures used were questionnaires, students' written computer notes and repeated process-oriented interviews. The results show the dominance of a superficial approach toward inquiry. This is evidenced by the students' fact-oriented computer notes and their self-reported, surface-level strategic actions. However, the results show a growing amount of collaborative discussion in the networked database. Collaborative networked discussions manifest an increase in deeper-level cognitive strategies and progressive student inquiries. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

High demand for suitably qualified, high-quality science teachers is undermined by elevated teacher burnout/attrition rates within the early years of teaching. Effective emotion management can alleviate feelings of burnout and is also linked theoretically to sustaining positive social bonds. Scant attention has been directed at the importance of emotion management and social bonds in science education research. This study presents a methodology for studying emotion management and social bonds, delivering novel outcomes that elucidate how these two phenomena are interrelated. Video recordings of classroom interactions and reflective accounts in an early-career science teacher's ninth grade class were analyzed through a combination of ethnomethodology and interpretive techniques. Situated actions that constitute emotion management at the classroom level impacted the status of bonds between the teacher and one of his students, ultimately leading to a breakdown in their relationship. Results of the study detail how social actions of numerous students and the teacher led to the co-construction of emotion management and how this impacted social bonds. Theoretical and practical insights about the co-constructed nature of emotion management and social bonds present novel perspectives that can help to avoid pathologizing the actions of individual students and teachers for sustaining positive social bonds. Implications for science teaching and teacher education are offered. Study outcomes extend previous perspectives on emotion management in science education, which treat emotion management as an individual cognitive phenomenon.  相似文献

Research and design activities are important focus points in international policies for secondary Science, Technology, Engineering and Mathematics (STEM) education. It is up to school teachers to implement and supervise these activities in the STEM classroom. However, not much is known about the attitudes teachers hold towards supervising research projects or design projects. In this study, a questionnaire to measure teacher attitudes towards supervising research activities and design activities in secondary school was completed by 130 Dutch teachers who taught the relatively new Dutch STEM subjects O&O (research and design) and NLT (nature, life, and technology). These integrated STEM subjects are project and context based and are taught in a limited number of schools. Important differences between these integrated STEM subjects are their student and teacher populations: NLT is taught in grades 10–12 by teachers with a qualification in a science subject, while O&O is taught in grades 7–12 and can be given by any teacher in secondary school. The results showed that on average, both O&O and NLT teachers had high self-efficacy scores on supervising research and design projects even when they had received no special education in doing so. Furthermore, the teachers in general viewed supervising research projects as a more relevant activity than supervising design. Since research and design activities are becoming more important in (inter)national curriculum standards, STEM teacher education and subsequent professional development should not only familiarize teachers with supervising research projects, but with design projects as well.

Student‐led design projects undertaken within healthcare settings raise considerable ethical challenges, primarily resulting from collaboration with service users. This article emerged out of the experiences of design from a New Zealand university undertaking real world projects in acute health care contexts. A human‐centred approach to design is underpinned by a requirement for students to immerse themselves in the user context to optimise design outcomes. Several issues exist in relation to the management of the ethical complexities arising from these projects. Multiple formal ethical review processes were triggered when students’ projects were defined as research. These processes were perceived as onerous and disproportionate to the scale of the projects, and students were ill equipped to identify ethical issues and engage with formal review processes. This resulted in either abandoned projects or the use of compromised methods. A review of codes of practice and design industry approaches identifies a gap in guidance for both students and qualified designers. Some designers describe their projects as service improvement, and not subject to formal ethical review. This article argues for embedding consideration of ethics in all design projects to enhance the process, to be true to the underpinning philosophy of human centred design and to produce ethically aware graduates. To achieve this, a multi‐pronged pedagogical approach which encompasses both hypothetical, class‐based and real‐world learning experiences is described, with the ultimate goal of normalising the consideration and development of ethical standards for students and best practice across the industry.  相似文献

In this paper, which is based on research from the EU-funded project Improving Progress through Formative Assessment in Science and Mathematics Education, we explore how iPads are used within formative assessment processes by six mathematics teachers and their classes in two secondary comprehensive schools in the Midlands of England. A design research approach is first used to develop and trial six lessons in which iPads are used in different ways within formative assessment processes. Through lesson observations, video analysis and teacher interviews we then examine how iPad technology contributes to these processes, the functions it performs and the distribution of activity between the main actors (teacher, technology and student). An analytic approach is developed which captures the interactions in visual representations, showing how the technology is often used as a form of communication but also performs more active functions which affect the role taken by the teacher in formative processes. The study offers insight into ways in which iPad technology contributes to effective student learning through formative assessment and introduces an analytic approach that may be useful for further studies.  相似文献

ABSTRACT

While assessment for learning (AfL) has been widely used in college English classrooms in China where teachers usually teach large classes, how AfL is implemented in the large-class higher education (HE) context is relatively underexplored. To address this gap, this study explores some of the challenges presented by large classes and the teachers’ coping strategies through case studies of three university English teachers’ AfL practices. Challenges are identified surrounding how the teachers dealt with (a) inadequate attention to individual students, (b) reduced opportunities for individualised feedback, (c) overwhelming marking responsibilities, and (d) involving students in assessment, with strategies of putting students in groups, matching names with faces, conducting teacher-student conferences, utilising technology to facilitate feedback processes, enabling peer feedback, and transforming students from assessees to assessors. Findings are framed around useful forms of AfL in large classes and the feasibility of AfL in terms of compromises between teacher agency and their temporal and contextual conditions. The paper concludes with implications for teacher assessment training, teacher education and policy-making.  相似文献

This paper reports on an investigation into the first time implementation of a technology education unit of work by a beginning primary school teacher. The researchers monitored the teacher's implementation of the unit across a 6 week period using an interpretivist research approach. A variety of data sources were drawn upon including teacher and student interviews, video and audio recordings of small group and whole-class interactions, and student-developed artefacts. Providing appropriate learning activities to assist students to develop understanding about patterns and shapes incorporated into buildings and other structures to enhance strength and stability was a challenge faced by the beginning teacher. However, she drew support from a teaching resource, which provided guidance and structure for the teaching of technology concepts and processes related to strength and stability of structures and materials. The resource helped her to develop learning activities that were appropriate to the topic and to the needs of the students in her class. Implications of the study relate to the needs of teachers grappling with teaching design and technology for the first time and the support that they can gain from predetermined planning and teaching models and well-developed teaching resources.  相似文献

Technological devices are widely used in various forms and for various purposes with educational systems. Teachers are required to not only use technology with the utmost efficiency, but to also act as role models for students in terms of appropriate use of technology. However, many teacher candidates are not aware of the educational use of technology classroom; hence, technology must be especially integrated into undergraduate teacher training programs through courses and field experience. Various methods, techniques, tools, and equipment are utilized in order to improve the efficiency of teaching and learning processes in the classroom, of which digital storytelling is one of them. The use of digital stories in education is beneficial both for teachers and students. For this reason, this research investigates the use of digital stories in mathematics education as well as the opinions and experiences of mathematics teacher candidates about creating, using, and evaluating digital stories. Data of the study were collected via semistructured interviews, transcribed, and content analyzed. The results of the study showed that prospective math teachers preferred GoAnimate program to create digital stories due to its ease of use, design, and the characters and visuals it suggests. Furthermore, the prospective teachers were found to aspire to use digital stories in their future careers.  相似文献
