<![CDATA[This research aim to develop the attempt peripheral conception the effective giration for the study of middle physics at school and university. Research approach used by research and development method (R&D). Product from this research is consisted of by two component, namely rotation table and operation guidance. Effectivity of peripheral experiment developed in this research is evaluated from two aspect, namely validity and practicality. Indicator for the examination of validity is contains validity, empirical validity and construct validity. For practicality test, the component of evaluations is empirical practicality and student opinion in a test-drive limited by entangling student of SMA.Technique analyse the data used in this research is descriptive analysis. Pursuant to gathering result and analyse the data, obtained by picture that attempt peripheral developed in this research own the very high effectiveness to nine of attempt items and high effectiveness to three attempt items. Thereby, attempt peripheral developed in this research can be expressed competent to be used in high school and university, especially to nine attempt item identified.]]>
