@article{2016,title={VALIDITY AND RELAIBILITY OF SCIENCE PROCESS SKILLS SCALE FOR 60-72 MONTHS OLD CHILDREN},abstractNode={The purpose of this study is to develop science process skills scale for 60-72 months old children. For scale development study, 53 items generated by the researcher were investigated by 3 teachers and 4 academicians and then the items were evaluated by utilizing Lawshe's technique. The scale was applied to 265 children aged 60-72 months who attend kindergartens in Istanbul city, districts of Kadıkoy, Besiktas, Atasehir and Umraniye in 2012-2013 school year. For construct validity, the factor structure of the scale was examined and by using varimax rotation technique, an analysis was conducted to decide whether the data was suitable for factor analysis. KMO and Barlett’s tests were used for this reason and the test result was found as .80. For the analysis regarding reliability of the scale, first Kuder Richardson coefficient was calculated. For the test-retest reliability of the scale, the scale was applied to 45 students for 3 weeks apart and the correlation between the scores was calculated. According to this, it was found that value of the scale was .90 at the first factor, .86 at the second factor, .82 at the third factor, .75 for the fourth factor and .84 for entire scale. It was also found that test-retest reliability was .96 at the first factor, .87 at the second factor, .64 at the third factor, .78 for the fourth factor and .89 for entire scale.},author={Banu ÖZKAN-Alev ÖNDER},year={2016},journal={The Journal of International Educational Sciences}}
