Abstract

The purpose of this study is to develop a practical performance assessment instrument of temperature and heat the material in class X SMA. The sample was taken by using stratified random sampling method. Conceptually construct of performance assessments at temperature and heat the material consists of three dimensions, namely: preparation, implementation and follow-up. Development of point statement on assessment component based on the study experts and panelists. Through study and validation expert panelists chosen 10 points or indicators. Reliability coefficients interater value is quite high above 0.7. Instruments were tested students at SMA in class X, the first stage are 256 students and the second stage are 224 students. Empirically, by testing confirmatory factor analysis is obtained the values of loading factor is abave 0.5 in the first and second trials. From the calculation of the value of Construct Reliability (CR) on the first and second test showed that reliability coefficient value is more than 0.9, and the value of Variance Extracted (VE) is greater than 0.5 which means the level of validity and reliability of a practical performance assessment instruments of temperature and heat materials in class X SMA is high. So it can be concluded that the practicum performance assessment instrument temperature and heat the material has good construct validity and reliability
