Teachers and artificial intelligence. The Logo connection

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.     

Developing language and cognition in young children with Logo

A Logo intervention was implemented to improve the language and problem-solving skills of four young mainstreamed children with developmental disabilities. To ensure that the children had a clear concept of Logo, a specially designed scope and sequence curriculum, with instructional aids, was developed. The children were tested in language and cognitive processing and gain scores were analysed after the intervention. While there were no statistically supportable conclusions attesting to the benefit of Logo in language and problem-solving, a qualitative assessment of gains supported the value of the project.     

Logo as a Strategy for Developing Thinking?

Instruction in the Logo programming language proceeds amid increasing concern about its educational value. Proponents claim that Logo-based instruction increases intelligence, whereas critics contend that children learn little about Logo or about anything else during such instruction. Reasoned argument about the pitfalls and prospects of Logo in the classroom requires a common interpretive framework, which is often obscured by the distinct conceptions of intelligence held by proponents and critics. Accordingly, the implications of two different root metaphors of intelligence for the study of Logo-based learning are traced. Development of ideal educational practices and outcomes for Logo learning within each framework follows, with a selected review of research to support some conjectures and refute others. This presentation includes discussion of weak versus strong problem-solving methods, transfer, "powerful ideas," and discovery-based learning. The article concludes with a partition of cognition into cognitive, metacognitive, and epistemic levels, and it relates these to Logo as a strategy for developing thinking.     

Reviving the Turtle: Exploring the Use of Logo with Students with Mild Disabilities

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.     

Linking logo,levels and language in mathematics

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.     

Fragile knowledge of angle in turtle geometry

This paper describes an investigation into how the use of Logo affects children's basic knowledge of angle. It shows that teachers should not assume that unstructured use of Logo with a minimum of teacher intervention will have a beneficial effect on children's knowledge of angle and how it is measured. It appears to be the case that children make erroneous adjustments to their conceptual knowledge of angle in order to accommodate the results of an acquired procedural interaction with the computer.     

Providing a computer based framework for algebraic thinking

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.     

Programming-languages as a conceptual framework for teaching mathematics

Formal mathematical methods remain, for most high school students, mysterious, artificial and not a part of their regular intuitive thinking. The authors develop some themes that could lead to a radically new approach. According to this thesis, the teaching of programming languages as a regular part of academic progress can contribute effectively to reduce formal barriers. This education can also be used to enable pupils to access an accurate understanding of some key mathematical concepts. In the field of heuristic knowledge for technical problem solving, experience of programming is no less valuable: it lends itself to promote a discussion of relations between formal procedures and the comprehension of intuitive problem solving and provides examples for the development of heuristic precepts (formulating a plan, subdividing the complexities, etc.). The knowledge gained in programming can also be used for the discussion of concepts and problems of classical mathematics. Finally, it can also facilitate the expansion of mathematical culture to topics in biological and physical sciences, linguistics, etc. The authors describe a programming language called ‘Logo’ adapted to objectify an enduring framework of mathematical experimentation.     

Teacher Research,Action Research: the Logo Action Research Collaborative

Action research is a form of professional inquiry in which the teacher's role is seen as key to educational improvement. This paper describes methodologies developed by the Logo Action Research Collaborative – a national network linking 100 teachers at nine sites – that facilitate and support collaborative inquiry by teachers into their own teaching practices, in order to understand, improve, develop, and incorporate new forms of student assessment, teaching methods, and curriculum. The project focused on the Logo computer language, a powerful learning environment for problem‐solving and mathematical inquiry. The authors provide background information on action research as an evolving discipline. They identify three phases of a year‐long action research cycle, and describe key strategies developed by the project to support teachers in taking on a research frame of mind, identifying areas of concern, and undertaking and completing action research projects. The paper includes several illustrative examples of action research investigations undertaken by teachers, and demonstrates the benefits to the students and teachers involved. It closes by making a case for the potential contribution of action research to current educational reform initiatives and school restructuring.
