PENGEMBANGAN PERANGKAT PENILAIAN KINERJA PRAKTIKUM FISIKA PADA PESERTA DIDIK SMP UNISMUH MAKASSAR

Abstract

This research is development research that aims to produce a performance assessment instrument of physics laboratory at SMP/MTs grade as well as the rubrics. In particular, the performance assessment instrument result was for assessing the performance of Physics laboratory Activity for Ohm's law experiment, series circuit and a parallel circuit experiment. The judgement results of the expert and practitioners in assessing the suitability between contents, construction, and languages of each items of the instrument showed that the instrument had been developed had met the criteria for validity and reliability. Simulation and test results also showed that the instrument had been legible and clearly incomprehensible by the user so that it could be used to assess the performance of student laboratory activities. The results of effectiveness test showed that; (1) data on the teachers response (peers) on the laboratory performance assessment (test of legibility) was of very good category; (2) the results of the use observation sheet of the instrumen by observer at least completedly done, (3) the data of laboratory Activities student performance score can be described according to the criteria assessed and, (4) the students respons towards the instrument (laboratory manual) was positive. Thus, we can conclude that the performance assessment instrument developed in this study had met the validtiy and reliability criteria and it could be used efficiently by the teacher in junior high of Unismuh Makassar.

Penelitian ini merupakan penelitian pengembangan yang bertujuan untuk menghasilkan instrumen penilaian kinerja praktikum Fisika tingkat SMP/MTs dan rubrik penskorannya. Secara khusus Intrumen penilaian kinerja yang dihasilkan adalah instrument kinerja praktikum Fisika untuk menilai kinerja praktikum  hukum Ohm, rangkaian seri, dan rangkaian parallel. Hasil penilaian pakar/ahli dan praktisi untuk menilai kesesuaian antar materi, konstruksi, dan bahasa pada setiap butir-butir instrumen penilaian menunjukkan bahwa perangkat yang telah dikembangkan telah memenuhi kriteria valid dan reliabel. Hasil simulasi dan uji keterbacaaan menunjukkan bahwa instrumen dapat terbaca dan terpahami dengan jelas oleh pemakai sehingga dapat digunakan untuk menilai kinerja praktikum peserta didik. Hasil uji kefektifan menunjukkan bahwa; (1) data tentang respon guru (teman sejawat) terhadap perangkat penilaian kinerja praktikum (uji keterbacaan) berada pada kategori sangat baik; (2) hasil lembar pengamatan penggunaan perangkat penilaian kinerja praktikum yang diisi oleh pengamat minimal terlaksana semua, (3) data nilai kinerja praktikum peserta didik dapat dideskripsikan sesuai dengan kriteria yang dinilai dan, (4) respon peserta didik terhadap terhadap perangkat pembelajaran (penuntun praktikum) positif. Dengan demikian maka instrumen penilaian kinerja Praktikum Fisika telah memenuhi kriteria valid dan reliabel dan dapat digunakan secara baik efeisien oleh guru di SMP Unismuh Makassar.
