PENGEMBANGAN PERANGKAT E-PORTOFOLIO ASSESSMENT LAPORAN PRAKTIKUM POKOK BAHASAN OPTIKA GEOMETRI DI MA

Abstract

The development research of e-portfolio assessment instrument was intended to afford its report of the report of practice in this research for geometrical optic that fulfills logic validity, empiric validity, and reliability. Data used in this research was the result of logic validity of e-portfolio assessment, the result of empiric validity from quesionaire of teachers who teach physics lesson at X class of MAN 2 Jember, and the result of reliability from Student Worksheet ( LKS) and the report of practice of XC, XE, and XI classes in MAN 2 Jember. The result of this research showed that assessment of logic validity was 4, the result of empiric validity was average scores from three teachers responses that showed 50,33, and the result of its reliability was obtained from doing Test of Homegeneity of Variances where showed that three variables of that groups were same with ( P-Value = 0,125). Based on the Sig. value showed the result P ( P-Value) = 0,992. As the explanation of the result above, the real level was = 0,05 it mean that Ho was accepted, so it can be concluded that there was not meningful vary of value average of those classes. That case showed that the report practice e-portfolio assessment instrument had valid and reliable.
