This paper examines the extent to which Logo-experienced children are able to mobilise their Logo-based knowledge to construct meaning for elementary algebraic concepts. It reports the results of an exploratory study which was part of a longitudinal investigation of the mathematical environment created through Logo programming. The study aimed at gauging the influence of children's Logo learning in facilitating their conceptualisation of algebraic variable, and their ability to formalise in a non-computational context.  相似文献

This paper presents a case study investigating the knowledge constructed by two 12 year-old children working with a geometrical Logo microworld allowing the Logo turtle to measure distances, and turns relative to previously constructed points on the plane. A qualitative analysis of data consisting of everything that the children said, typed and wrote on paper during the 15 hours of the research, provided evidence of the children's developing use of concepts belonging to Plane Geometry. The measuring of angular and length quantities, enabled them to conjecture, reflect on and manipulate triangle properties and relations traditionally associated with Euclidean Geometry. Their developing awareness of the existence of geometrical relations in their work, encouraged an increase in their readiness to use and reflect on them. The paper concludes that the generation of learning environments such as the above may well enhance the opportunity for children to form inductive geometrical understandings.  相似文献

When learning to program in Logo, many young children experience difficulties using the right and left turn commands. This paper looks at the spatial concepts required for the understanding and manipulation of these commands. We begin by providing an overview of research on children's Logo learning and point to specific problems children have with right and left commands and to related characteristics of standard Logo systems that seem to contribute to these problems. To shed further light on the source of these problems, the psychological-cognitive literature on the development of spatial concepts concerned with the use of frames of reference and obliques is reviewed. It is argued that in order for children to handle meaningful programming projects they need to master a set of prerequisite skills. These skills, involving the development of elaborated and explicated spatial concepts, include a distinction between right and left, the intentional reference to the Turtle as a frame of reference, the assignment of appropriate axes and the application of units of measurement for determining distance and angles. We conclude by suggesting that children need to be exposed to Logo programs designed to facilitate the development of spatial concepts which would enable the successful progression to more complex Turtle Geometry programming tasks.  相似文献

This article describes a three-phase program for training special education teachers to teach Logo and artificial intelligence. Logo is derived from the LISP computer language and is relatively simple to learn and use, and it is argued that these factors make it an ideal tool for classroom experimentation in basic artificial intelligence concepts. The program trains teachers to develop simple demonstrations of artificial intelligence using Logo. The material that the teachers learn to teach is suitable as an advanced level topic for intermediate- through secondary-level students enrolled in computer competency or similar courses. The material emphasizes problem-solving and thinking skills using a nonverbal expressive medium (Logo), thus it is deemed especially appropriate for hearing-impaired children. It is also sufficiently challenging for academically talented children, whether hearing or deaf. Although the notion of teachers as programmers is controversial, Logo is relatively easy to learn, has direct implications for education, and has been found to be an excellent tool for empowerment-for both teachers and children.  相似文献

In his book Mindstorms (1980) Papert discusses Turtle Geometry as ego-syntonic or fitting the ways of thinking of the child as a geometric knowledge builder. The van Hiele theory (Wirzup, 1976) looks at geometric knowledge building as occuring through a necessary sequence of levels. Thus if Turtle Geometry is ego-syntonic it would seem that one could apply these van Hiele levels to better describe and understand this form of geometry. It is the first purpose of this paper to provide such an analysis.Using Logo to do Turtle Geometry requires that a child (or learner at any level) do geometry through the deliberate use of language. Thus one ought also to be able to relate theoretically levels of language use to Turtle Geometry. It is a second purpose of this paper to relate a language use framework suggested by the work of Frye (1982) to the language activities of Turtle Geometry.  相似文献

This paper describes and presents the findings of a study which aimed to trace the development of pupils' use and understanding of algebraic ideas within a Logo programming context relating this to their use and understanding of similar ideas within a non-computational context. The research consisted predominantly of a three year longitudinal case study of four pairs of pupils (aged 11–14) programming in Logo during their normal school mathematics lessons. The data included video recordings of all the case study pulils' Logo sessions, and individually presented Logo and algebra structured interviews. The overall conclusion of this research is that Logo experience does enhance pupils' understanding of algebraic ideas, but the links which pupils make between Logo and algebra depend very much on the nature and extent of their Logo experience.  相似文献

The study compares the levels of response to angle/rotation problems presented on screen with a Logo microworld with the levels of response to similar problems presented on paper. Pairs of children aged from 9 to 11 who had little or no experience of Logo completed the problems in about 40 minutes. Pairs of children completed the problems over a period of eight weeks. The responses, classified using the SOLO taxonomy (Structure of Observed Learning Outcomes), suggested that the effect of the immediate feedback of the screen turtle heading was to inhibit moves to a higher level of response compared to those levels of response reached when responding to paper tests.  相似文献

Primary teachers as readers   总被引:1,自引:0,他引:1  
In the context of the continued pressure and politicisation of the teaching of reading in England, the United Kingdom Literacy Association (UKLA) sought to ascertain patterns in primary teachers' reading, both personally and professionally. The project, undertaken in 11 Local Authorities in England, explored 1200 primary teachers' personal reading habits and preferences, investigated their knowledge of children's literature, and documented their reported use of texts in the classroom through a questionnaire. In addition, it sought to establish the extent of the teachers' involvement with and use of local area/school library services. This paper reports on the findings with reference to the teachers' personal reading, the frequency of this reading and the sources they use to select their reading material. It also considers the teachers' favourite childhood texts and the books they identified as highly significant to them, as well as their perceptions of the importance of literature. Connections are made to the data gathered about their knowledge of children's literature, and how primary teachers decide which literature to work with in the classroom.  相似文献

In this case study, a group of nine 4th grade children were introduced to the Logo programming language during three 90-minute sessions over a four-week period. They attended a private university-based laboratory school serving students with various learning disabilities. This project demonstrated that a classic version of Logo captured the students’ interest. It was a viable source of interactive challenge and problem-solving experience that provided students with a great deal of pride, intrinsic reward, enjoyment, and sense of ownership of learning. The process of overcoming obstacles while programming with Logo may be especially beneficial for students with mild disabilities.  相似文献

Logo Experience:     
《学校用计算机》2013,30(2):57-64
This Study investigated whether or not generalized learning experiences with Logo would yield enhanced understanding of relative position and direction for fifth and sixth graders. It was assumed that manipulating the Logo turtle would benefit students in these important geography skills. After one school year of Logo instruction the treatment group outperformed the control group on three of four measures of relative position and direction skills, one of which was statistically different.  相似文献

Recognition of the important role television plays in children's lives has led during the 1970s to the beginnings of an effort to modify television's impact on children by teaching them how to manage their viewing behavior, how to understand the medium, and how to evaluate its content (so-called, “critical television viewing skills”). The objectives pursued by critical viewing curricula are discussed, and it is argued that critical viewing is strongly related to critical thinking. A review of studies of the effects achieved by television curricula indicates that television curricula can be effective in increasing children's knowledge of the medium and in altering children's perceptions of television content. However, there is little evidence that curricula can modify television's effects on children's attitudes and behaviors, and curricular effects on children's viewing behavior at home have yet to be demonstrated. The research conducted is evaluated, and suggestions are made for future work in this area.  相似文献

This study evaluated a school-based child sexual abuse prevention program which consisted of separate 2-hour workshops for children, parents, and teachers. Questionnaires concerning the children's knowledge about sexual abuse prevention and level of emotional distress were developed and administered to 88 children, ages 5-12, and 60 parents before and after the program. In addition, 12 teachers completed questionnaires about the children's level of emotional distress within 2 weeks after the program. Comparison of the children's knowledge before and after the program showed significant increases in knowledge about strategies for coping with potential abuse situations. Also individual children's responses were compared with their parents' responses. After the program the parents had a more accurate appraisal of their children's knowledge, and in addition, there was a significant increase in how much parents reported that they had talked with their children about sexual abuse. In terms of possible adverse emotional effects of the program, neither teachers nor parents noticed signs of increased emotional distress. In addition, the children reported that the program made them feel safer and better able to protect themselves. The findings support the value of providing sexual abuse prevention programs to children.  相似文献

This article describes an investigative pilot study that was carried out with six children (mean age 6 years and 8 months) who worked in one of three gender pairs (girl/girl, boy/boy and boy/girl) to solve tasks with the floor and screen versions of the Logo turtle. The study revealed that when young children work collaboratively in Logo tasks, there may be initial differences in performance, based on gender, whereby the performance of the girls is less economic in terms of the number of moves made and the time taken to task completion, and more accurate in relation to the number of errors made and their ability to reproduce specific items. It is suggested that the extent and nature of the differences will vary according to the task format and with experience in the domain. The study provides qualitative information about the strategies and interactions of young children in a novel problem‐solving context. As such, the study has important practical implications for the organisation of learning opportunities related to the use of computers in early childhood environments, since it highlights the need to describe performance in the context of the task used and over a reasonable period of time.  相似文献

In this article, we provide an overview of the emerging area of research concerning individual differences in children's memory, suggestibility, and false event reports. We begin with a discussion of recent research on children's false event memories. We then review research and theory concerning sources of individual differences in children's memory and suggestibility, including both cognitive (e.g., understanding of dual representations, source monitoring, imaginativeness, and event knowledge), and social-personality (e.g., attachment styles and temperament, parent-child communication, and sequelae of maltreatment) influences, and we highlight implications of these sources for children's false event reports. Finally, we examine how individual-difference factors proposed to mediate adults' false memories relate to those that may mediate children's false memories.  相似文献
