Description
Summary:Abstract. This research aimed to develop a valid and reliable cognitive test device for measuring the professional competence of the future teachers in the fishing vessel nautical science with a proper procedure. The method used in this study was research and development method with the following procedures: identification of measurement purposes, the development of test specifications, item writing, item review of the test (validity test), trial test 1, items analysis 1, reliability test, trial test 2, items analysis 2 , and the construction of the final test device. At the beginning of the development of test specifications and test item writing, there were 65 test items being developed and as the development going, the number of test items was decreasing. After being tested by 3 experts in the fishing vessel nautical science, the items have been reduced to 60 test items which then were being constructed to be the 1st trial test device. Following this, the 1st items analysis was carried out in accordance to classical test theory which consists the level of difficulties, item discrimination, and effectiveness of distractors. From this analysis the number of items has been reduced to 29 test items which were constructed to be 2nd trial test device. Reliability test was conducted for the 1st trial test using the internal consistency approach by calculating the reliability of Kuder Richardson (KR20). The result showed that the reliability coefficient is 0.71 which indicated that the 1st trial test was a reliable test. The 2nd trial test was conducted and followed by the 2nd items analysis which left 19 test items to be constructed as a final form test devices. Keywords : test development, competency measurement, fishing vessel nautical science Abstrak. Penelitian ini dilakukan dengan tujuan untuk mengembangkan sebuah perangkat tes kognitif yang valid dan reliabel untuk pengukuran kompetensi profesional calon-calon guru SMK Keahlian NKPI melalui prosedur yang benar. Metode penelitian yang digunakan dalam penelitian ini adalah riset dan pengembangan. Prosedur yang dilalui dalam penelitan ini yaitu : identifikasi tujuan pengukuran, pengembangan spesifikasi tes, penulisan butir soal, penelaahan butir tes (uji validitas), uji coba tes 1, analisa butir tes 1, uji reliabilitas, uji coba tes 2, analisa butir tes 2, dan perakitan bentuk akhir tes. Pada awal pembuatan spesifikasi tes dan penulisan butir, jumlah butir yang dikembangkan berjumlah 65 butir tes. Seiring proses pengembangan tes dilakukan, jumlah butir tes mengalami degradasi (penurunan). Setelah melalui tahap telaah butir (uji validitas) yang dilakukan oleh 3 orang ahli di bidang NKPI, butir tes mengalami pengurangan 5 butir tes sehingga tersisa 60 butir tes untuk dirakit menjadi perangkat tes uji coba 1. Setelah uji coba 1 dilakukan dilanjutkan dengan analisis butir 1 yang dilakukan sesuai teori ujian klasik yang terdiri dari tingkat kesukaran, daya diskriminasi butir, dan efektivitas distraktor. Dari analisis tersebut, jumlah butir soal pun mengalami pengurangan hingga tersisa 29 butir tes untuk dirakit menjadi perangkat tes uji coba 2. Dari hasil uji coba 1 pun dilakukan uji reliabilitas menggunakan pendekatan konsistensi internal (internal consistency) yaitu dengan perhitungan reliabilitas Kuder Richardson (KR20). Diperoleh nilai koefisien reliabilitas sebesar 0,71 yang menunjukkan bahwa perangkat tes tergolong reliabel. Uji coba 2 dilakukan dan diteruskan dengan analisa butir 2, kembali lagi butir soal mengalami pengurangan hingga tersisa 19 butir tes untuk dirakit menjadi perangkat tes bentuk akhir.
