Development of an Attitude Measure Oriented to Biotechnology for the Pre-Service Science Teachers

Abstract

The aim of this study was to develop valid and reliable measures for the attitudes of pre-service sciences teachers towards biotechnology. The sample used in this study consisted of 384 science
students. This study was conducted at four stages including determining the measure controls, expert opinion evaluations, pre-trials, and validity-reliability. The obtained data were analyzed by SPSS 13.00 and results were evaluated by factor analysis. The final measure developed according to these stages includes a total of 40 items where 14 of them were negative and 26 were positive. It was found that the measure fits to the sample group with 0.000 level, the KMO (Kasier-Meyer-Olkin) value was 0.827, and the Barlett test value was 4186.420. The Cronbach Alpha reliability constant of the
measure was calculated as 0.75. The findings showed that the validity and reliability of the measure were acceptable.
