The data were collected by means of questionnaires answered by forty-one mathayom suksa four physics teachers and four hundred and twenty-six students studying physics in mathayom suksa four in 1981. The analysis of the data indicated that the teachers and students thought that the suitability and quality of the physics laboratory instruments were fair. The problems in using them were that they were easily damaged, too small or too large and some of them had problem of friction. Furthermore the comparison of the opinions on the suitability and the quality of the physics laboratory instruments between teachers and students, male and female students, that there no signification differences at .05 level except the opinions on the Ticker timer that there were significant difference at .01, .05 and .05 respectively.
