This document consists of extracts from "Numeracy in Papua New Guinea: An Investigation with Particular Reference to the Relationship between Number Skill Teaching and the Use of the Calculator," a doctoral thesis submitted to the Loughborough University of Technology in April 1982. The material is made up of chapters and parts of chapters, including: (1) Introduction and Background to Papua New Guinea; (3) Adult Numeracy With the Calculator in Papua New Guinea; (4) The Use of the Calculator in Full-Time Education in Papua New Guinea; (6) Rationale and Critique; (7) Summary and Conclusions; and (7) Appendix. The original thesis was the result of 4 years of work in Papua New Guinea. It is noted that the Department of Commerce had identified poor number skills as a major factor restricting business development. Calculators were quickly viewed as the route to the only possible solution. A government grant enabled the potential for general adult numeracy to also be studied. Materials were prepared and the reactions of village people to calculator-oriented instruction was tested. It is felt calculators represent a possible means of overcoming the lack of number skills in individuals, nations, and disadvantaged groups anywhere in the world. (MP)
