The Study of Developing an the 7th Class ”Solar System and Beyond" Unit Achievement Test and the Astronomy Attitude Scale

The aim of this study is to develop an attitude scale towards astronomy at middle school level and an achievement test that appropriate the educational program aims for the "Solar System and Beyond" unit. The validity and reliability study of the attitude scale for astronomy was applied with 380 middle school students. The reliability and validity study of the achievement test for the Solar System and Beyond unit was applied with 266 middle school students. The achievement test developed as a result of reliability and validity study consists of 36 multiple choice items. The reliability coefficient of the achievement test developed for the 7th grade ’Solar System and Beyond” unit was calculated as .94. While attitude scale was developed, structure validity and reliability studies were done. The scale was three-dimensional and consisted of 14 items. The Cronbach Alpha internal consistency coefficient for the reliability of the scale was .91. As a result of the findings, an achievement test for 7th grade "Solar System and Beyond" unit and an attitude scale for astronomy at middle school level were developed
