An in-service program on the use of the hand-held calculator for mathematics teachers in grades five through eight

TL;DRAbstract

The study was motivated by the lack of a formal in-service program for Newfoundland teachers on the use of the hand-held calculator in mathematics. -- The purpose of the study was to evaluate the effectiveness of an in-service model developed by the investigator, on the use of the hand-held calculator for mathematics teachers in grades five through eight. -- The sample consisted of 30 mathematics teachers in grades five through eight employed by the Port aux Basques Integrated School Board. The model was evaluated in terms of its effectiveness in changing the teachers’ attitudes toward the use of calculators in mathematics instruction, and in increasing the teachers’ understanding of the basic arithmetic operations on a calculator. -- To test the program’s effectiveness two null hypotheses were set up: -- 1. There is no significant change in teachers’ attitudes toward calculators as a result of the in-service program. -- 2. There is no significant change in calculator knowledge as a re
