Abstract

This study was aimed at constructing an authentic assessment model which can'be used to assess junior high school students' competencies in science (physics). Specifically, it was to construct: (a) a set of competencies and indicators, which could be measuled,thrgyOh integrative and authentic assessment, (b) a description of an authentic assessmdnt model to ass6ss the students' competencies in Physics, (c) a description of students' and teachers' responses to the authentic assessment model to be developed, and {d) informatiol ol !!? effectiveness of the authentic assessment model, to be developed, about the students' achievement, interest, attitude, and learning styles of Physics. This research was a Research and Development (R and D) research, and was conducted in two phases: (1) the phase of development ani validation of the model, and (2) the testing of the effectiveness and applicability of the model. ln the first phase, the researcher used a developmental research model, whereas in the second phase, he used a quasi-experimental pretest post-test control group non-random design. The'subjects for the try out of the authentic assessment model were Physics teachers and ihe students of state junior high schools (SMPN) in Bandar Lampung. The schools chosen were SMPN 1, SMPN 12, and SMPN 18. They were all located in Bandar Lampung. One class was selected from each of the three schools. The schools selected for the try out of the effectiveness and applicability of the authentic assessment model were SMPN 14 and SMPN 22 Bandar Lampung. Two classes were selected from each of the two schools, one class as an experimental group and the other as a control group. The result is in the form of an authentic assessment modelwhich has been developed to assess the students'competencies in science (physics). The competencies assessed by the model cover the assessment of conceptual understanding, conceptualization, application, methodology, and affective, and holistic scores shown by students' chart of competencies. The instruments of the research are the students' sheet assessment (SSA), and observation sheets (OS), whose validity and reliability have been tested. The validity and reliability of the instruments for the authentic assessment model are shown by the results of the try out. The results indicated that there are no significant differences among the raters in assessing the appropriateness of the components of the SSA and OS. The inter raters' s@res also show the appropriateness among indicators and assignments of SSA and OS in assessing the arrangement of the SSA. Furthermore, the results of the try out of the effectiveness and applicability of the authentic assessment model showed that the implementation of this model is effective in increasing the students' attitudes towards Physics, the students' learning interest in Physics, the students' learning styles, and the students' conceptual understanding of Physics. The change of the students' attitudes toward Physics, their interest in learning Physics, their learning styles, and their conceptual understanding of physics is more significant than that using the conventional assessment model.
